We often see some construction fiber distribution boxes on many construction sites, which will be enclosed with very eye-catching colored fences. What about the inside of the fiber optic distribution box? What are the installation requirements? Today, let's follow China Fiber China Fiber Optic Splice Closure Manufacturers to learn more about this.

Optical fiber distribution box is a low-voltage distribution device, which is formed by assembling switching equipment, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Optical fiber distribution box is also called distribution cabinet, which is the general designation of motor control center.

The optical fiber distribution box is mainly composed of two parts

One is the complete set of components, namely the Optical Fiber Distribution Box shell and its related accessories.

The second is electrical components and related accessories, namely air switch and its required accessories.

The cabinet consists of the following parts: circuit breaker; Leakage protection switch; Double power automatic transfer switch; Surge protectors; Electricity meter; Ammeter; Voltmeter.

Leakage protection switch: it not only has leakage protection function, but also trips when people touch the live line to ensure personal safety. it is the main function of leakage protector. If the electrical equipment is not well insulated and leaks electricity to the casing, the leakage protector will trip to prevent human body from touching and getting an electric shock. At the same time, it has the functions of current interruption, overload protection and short circuit protection.

Working principle of watt-hour meter: when the watt-hour meter is connected to the circuit, the magnetic flux generated by the voltage coil and the current coil passes through the disk. these magnetic fluxes are in different phases in time and space, and eddy currents are induced on the disk respectively. due to the interaction between magnetic flux and eddy currents, the rotating torque is generated to rotate the disk, and due to the braking effect of magnetic steel, the rotating speed of the disk reaches uniform motion.

Watt-hour meter: It is commonly used by electricians and is an instrument for measuring electric energy, commonly known as watt-hour meter.

Dual-power automatic transfer switch: the dual-power automatic transfer switch is an automatic transfer system of power supply selection and selection. It is suitable for continuous power conversion of any two power sources such as UPS-UPS, UPS- generator, UPS- commercial power, etc.

Surge protector: also known as lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When spike current or voltage is suddenly generated in an electrical circuit or a communication circuit due to external interference, the surge protector can conduct shunt in a very short time, thereby avoiding damage of surge to other equipment in the circuit.

Optical Fiber Distribution Box is the lowest level control and protection facility in the power system, and is the most basic link to ensure the safe operation of the power system.

It has a great chance to contact with workers, but due to its large quantity, wide distribution and low value products, it is often ignored by the power department of the equipment, thus making many optical fiber distribution boxes out of control, causing unsafe factors and increasing the risk of electric shock and electrical fire.

Therefore, we must pay attention to the safe selection and use of optical fiber distribution box.

Second, the choice of optical fiber distribution box protection type optical fiber distribution box protection type should be selected according to the conditions of the workplace.

(a) in the relative humidity is not more than 75%, and no dust, no corrosive gas or vapor, no flammable and explosive substances less dangerous places, the optical fiber distribution box can choose open type.

(2) Protective type shall be used in particularly humid places with relative humidity close to 100% and places with corrosive gas or vapor.

(3) Dust-proof distribution boxes shall be selected for dusty places that can generate a large amount of dust.

(4) Dust-proof type shall be selected for Class H-1 and Class H-2 fire hazard sites with combustible liquid, suspended or accumulated combustible dust or combustible fiber;

In the H-3 fire hazard site with solid combustible substances, the protective type can be selected. (5) Selection of explosive hazardous sites.

Nbstarlite is the choice of China Fiber Optic Splice Closure Manufacturers. We are your safety guarantee.

　　The switchgear, measuring instruments, protective appliances and auxiliary equipment, etc. assembled in a closed or semi-enclosed box or screen width so as to constitute a fiber-optic distribution box, so what are the safety technical requirements of the fiber-optic distribution box, the following to follow the China Fiber Optic Splice Closure Manufacturers to carry out this specific understanding of it.

　　1, all fiber optic distribution box door should be equipped with a lock, shall not be in the fiber optic distribution box and switch box hooked up or plugged in other temporary electrical equipment, switch box is strictly prohibited to place debris.

　　2、Each electrical equipment shall have its own special switch box. Each electrical equipment at the construction site should have its own special switch box, and must meet the requirement of "one machine, one gate and one leak", and it is strictly prohibited to use the same switchgear to directly control two or more electrical equipment (including sockets). There must be a leakage protector in the switch box, the rated leakage action current should not be greater than 30ma, the leakage action time should not be greater than 0.1s.

　　3, the electrical box, switch box should be installed on the right side, firm, not upside down, skewed. Fixed fiber optic distribution box, switch box bottom and ground vertical specific should be greater than 1.3m, less than or equal to 1.5m; mobile distribution box, switch box bottom and ground vertical distance should be greater than or equal to 0.6m, less than or equal to 1.5m.

　　4, into the high-voltage fiber-optic distribution box power line, strictly prohibited with a pin connection; fiber-optic distribution box, switch box box body material, generally use steel plate, can also use insulating board, but should not use wooden materials; the distance between the electrical box should not be too far. The distance between the Optical Fiber Distribution Box and the switch box should not exceed 30m. The horizontal distance between the switch box and the fixed electrical equipment should not exceed 3m.

Generally, the low-voltage forest is formed by assembling switch equipment, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen to form a low-voltage Optical Fiber Distribution Box according to electrical wiring requirements. During normal operation, the circuit can be switched on or off by means of manual or automatic switches.

Optical fiber distribution box has the characteristics of small volume, simple installation, special technical performance, fixed location, unique configuration function, no site limitation, common application, stable and reliable operation, high space utilization rate, small occupied area and environmental protection effect.

Optical fiber distribution box has the characteristics of small volume, simple installation, special technical performance, fixed location, unique configuration function, no site limitation, common application, stable and reliable operation, high space utilization rate, small occupied area and environmental protection effect. It is the control center that directs all kinds of components in the power supply line to distribute power rationally, the control link that reliably receives the upper power supply and feeds out the load power correctly, and the key to obtain whether users are satisfied with the power supply quality. Improving the operational reliability of power fiber distribution box is the goal of the project.
