Optical Fiber Distribution Box Knowledge Introduction

Most of the words "Optical Fiber Distribution Box外部リンク" may sound strange, but those who come into contact with it will not be so strange. So today, China Fiber Optic Splice Closure Manufacturers外部リンク will introduce the basic knowledge of optical fiber distribution boxes in detail for everyone.

Distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box), and is the final equipment of distribution system. Distribution cabinet is the general designation of motor control center. The power distribution cabinet is used in occasions with relatively scattered loads and fewer circuits. The motor control center is used for occasions with concentrated load and more loops. They distribute the electric energy from a circuit of the upper distribution equipment to nearby loads. This class of equipment shall provide protection, monitoring and control of load.

(1) Class I power distribution equipment is collectively referred to as power distribution center. They are centrally installed in the substation of the enterprise and distribute electric energy to the subordinate distribution equipment in different locations. This class of equipment only depends on step-down transformer, so the electrical parameter requirements are higher and the output circuit capacity is larger.

(2) Secondary power distribution equipment is the general designation of power distribution cabinet and motor control center. The power distribution cabinet is used when the load is scattered and the circuit is less. The motor control center is used for occasions with concentrated load and more loops. They distribute the electric energy from a circuit of the upper distribution equipment to nearby loads. This class of equipment shall provide protection, monitoring and control of load.

(3) The final power distribution equipment is always called lighting power fiber distribution box. They are far away from the power supply center and are scattered small-capacity power distribution equipment.

What are its installation requirements? The installation requirements of distribution boards (boxes) are: the distribution boards (boxes) shall be made of non-combustible materials; Open power distribution boards can be installed in production sites and offices with low risk of electric shock. Enclosed cabinets shall be installed in processing workshops, casting, forging, heat treatment, boiler rooms, woodworking rooms and other places with high electric shock risk or poor working environment. Closed or explosion-proof electrical facilities must be installed in hazardous workplaces with conductive dust or flammable and explosive gases. All electrical components, instruments, switches and circuits of the distribution board (box) shall be arranged neatly, installed firmly and operated conveniently. Floor mounted plate (box) bottom surface should be 5 ~ 10 mm higher than the ground; The height of the center of the operating handle is generally 1.2~1.5m;; There are no obstacles within the range of 0.8~1.2m in front of the plate (box); The connection of protection wires is reliable. Outside the board (box), there shall be no naked charged body exposed. Electrical components that must be installed on the outer surface of the board (box) or the distribution board must have reliable screen protection.

How to choose a household Optical Fiber Distribution Box外部リンク is introduced to you by the following China Fiber Optic Splice Closure Manufacturers外部リンク.
Water and electricity installation has always been a key point in house decoration, which directly affects your daily life in the future. Optical fiber distribution box is home
The good installation of the main control switch and optical fiber distribution box of the medium circuit is helpful to better control the circuit in the home. Therefore, we need to pay special attention to the decoration process. Let's learn a little about the installation of optical fiber distribution box.

Today, let's introduce how to choose and buy a household optical fiber distribution box. What should we pay attention to?

1. The number of poles is divided into three types: 1P, 1P+N and 2P. The difference between these three pole numbers is: 1P circuit breaker can only control the on-off of the live wire and provide protection for the live wire; The 2P circuit breaker can simultaneously control the on-off of the zero-wire and provide protection for the zero-wire at the same time. The 1P+N circuit breaker is between the two-it can only control the on-off of the live wire, but at the same time provide protection for the zero line and live wire. Therefore, only looking at the function, we also know that 2P circuit breaker is the best, followed by 1P+N.

2, function selection fiber distribution box air switch comes with two kinds of protection function, overload protection and short circuit protection. In addition to this, additional protection functions need to be added through additional installation accessories.

3. The number of optical fiber distribution box loops (switches) with the most ideal number of loops should be 1+x+y+z-1 refers to the main switch; X refers to the number of rooms and is used to control the common sockets in each room. Y refers to the number of high-power electrical appliances and is used to control each high-power electrical appliance (all electrical appliances requiring open circuit breaker or 16A three hole socket belong to high-power electrical appliances); Z refers to the number of lighting circuits (2~3 circuits are usually used for lamps and lanterns, and 1 circuit is generally used). This picture is provided by the registered user "knowledge king" with feedback of copyright statement.

4, brand selection quality is good, there is a guarantee of optical fiber distribution box, security performance is more guaranteed. Large brands often have guaranteed product quality, good after-sales service and low failure rate. Therefore, we should try our best to choose brand products and avoid choosing optical fiber distribution boxes from small manufacturers when the economy allows, so as not to cause economic property losses.

4. Practicality The practicability of optical fiber distribution box is very important. If the volume of optical fiber distribution box is too large and the price of optical fiber distribution box is too high, resources will be wasted. In order to make the optical fiber distribution box practical, we must start with the number of loops and poles in the optical fiber distribution box.

Precautions For Use Of Optical Fiber Distribution Box

Optical fiber distribution box is a kind of thing that can reasonably distribute electric energy and facilitate the opening and closing operation of circuits. It has high safety protection level and can directly show the conduction status of circuits. It is widely used in power generation and distribution stations. Next, let's follow Optical Fiber Distribution Box外部リンク to learn about it.
1. When installing the optical fiber distribution box, try to install it in a ventilated place, so it can form air convection to dissipate heat from the optical fiber distribution box.
2. In addition to insisting on ventilation, the appliance of the box body should be used as far as possible to avoid direct sunlight at noon. The ground should be made of non-sand and gravel.
3. When using in high temperature season, the equipment shall be prevented from running for a long time and the heat released by the equipment in the optical fiber distribution box shall be reduced as much as possible.
4. The box body of the China Fiber Optic Splice Closure Manufacturers外部リンク can be sprayed with a coating with heat insulation function on schedule to reduce heat radiation, thus contributing to the heat dissipation of the box body and achieving more and more ideal effects.

Products Introduced By China Fiber Optic Splice Closure Manufacturers

Optical fiber distribution box is a connection equipment used in optical cable connection in the communication industry. During installation, it is open air and cannot be prevented from being damaged. Therefore, its maintenance must be done well. Only by doing a good job of maintenance can the occurrence of faults be successfully reduced. Next,China Fiber Optic Splice Closure Manufacturers外部リンク will give you a specific introduction on how to do a good job in this aspect of maintenance.

Due to the outdoor setting, the optical fiber distribution box will lead to water ingress, insolation and slow aging. It is conceivable that this will directly affect its service life. Moreover, the waterproof performance of this product is very poor, and the impact is due to the weather. Once the optical fiber distribution box enters the water, it will cause short circuit, which is easy to cause large-scale power failure. Every time after the rain, most of the optical fiber distribution boxes will be burnt out, which will greatly increase the maintenance workload of the device. The reason why this product is easy to enter water is that the space in the box is small. The power supply inlet of 35 square millimeter cable is fixed with plastic expansion pipe, thus there is no room for waterproof bending, resulting in rainwater flowing to the live terminal along the cable. As the gap of the terminal is small, the insulation measures are not in place, and it is easy to short circuit after entering water. In addition to this product's own design defects, there are radiating holes and wiring holes around it, which become water inlet holes when it rains.

In addition, maintenance personnel should also inspect and maintain the low-voltage Optical Fiber Distribution Box外部リンク in use as scheduled, re-crimp the wires in the box in time, re-process the insulation strength, replace the damaged wires or wires with insufficient insulation and serious aging in time, and install optical cable splice boxes when necessary to prevent excessive wiring.

Plastic Injection Parts Manufacturers How To Choose

What to consider when choosing a manufacturer of Plastic Injection Parts外部リンク? The products of plastic injection parts are used in many fields of life. There are many manufacturers engaged in plastic injection parts in the market. Which one of the many injection parts processing factories will you choose? This problem is of concern to many customers, so it is more important to know the factors that need to be considered when choosing the manufacturer of plastic injection parts.

Factors to be Considered in Correctly Selecting Manufacturers of Plastic Injection Parts
1. Injection molding equipment
In the process of selecting the manufacturer of plastic injection parts, one of the considerations is the equipment used by the manufacturer, because the quality of injection molding equipment affects the quality of injection molding products. The price quoted by the plastic injection parts factory with better injection equipment may be a little higher, because the injection equipment purchased by the injection manufacturer is expensive and needs to be taken into account as the injection cost. Of course, the factory can make a batch of samples first. After carefully observing the advantages and disadvantages of the products, we should consider the choice.
2. Delivery Time
When choosing a plastic injection part factory, we should also observe its delivery time. Everyone hopes that they can get their own goods as much as possible. If the production capacity of the injection part factory is limited and cannot deliver on schedule, a series of subsequent troubles will result. Therefore, we should choose a plastic injection part factory that can complete the requirements of plastic injection parts within the specified time period. Therefore, the timing of delivery is an important factor to consider when choosing a plastic injection parts factory.
3. After-sales problems
In the process of determining the manufacturer of plastic injection parts, we should also pay attention to the problems after delivery. This is because the transportation and after-sales of plastic injection parts can be relatively perfect, which saves a lot of trouble, especially when some injection parts need to be reworked, it is good that the manufacturer can come up with a practical and feasible scheme quickly.
Therefore, the manufacturer of injection molded parts should first consider the injection molding equipment purchased by the manufacturer, the delivery time, after-sales transportation, etc. It is more important that the manufacturer of plastic injection Stamping Parts外部リンク can provide a complete set of solutions from proofing production to after-sales transportation.
