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.
