Introduction to electric box

The electrical box is mainly used to provide operating power for vacuum circuit breakers and other high-voltage switches. The electrical box adopts the input voltage of 220V or 380V through the silicon controlled voltage regulation and rectification, and the output DC has the characteristics of output DC voltage with multiple adjustable current or AC voltage, and the function of single opening and single closing operation.

Effect

The electric box is the control center that commands all kinds of components in the power supply line to distribute the electric energy reasonably. It is the control link that receives the upper power supply reliably and feeds out the load electric energy correctly. It is also the key to obtain the satisfaction of the user for the power supply quality. To improve the operation reliability of power electrical box is the goal of creating high quality project.

In general, the electrical box is composed of switchgear, measuring instruments, protection appliances and auxiliary equipment assembled in closed or semi closed metal cabinet or on screen according to the electrical wiring requirements. In normal operation, the circuit can be turned on or off by means of manual or automatic switch. In case of fault or abnormal operation, cut off the circuit or give an alarm with the help of the protection appliance. With the help of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can be adjusted to prompt or send signals for deviation from normal working conditions.

The purpose of the electric box is to distribute the electric energy reasonably and to facilitate the opening and closing operation of the circuit. It has a high level of safety protection, and can intuitively display the on state of the circuit.

Characteristic

The electric box has the characteristics of small volume, simple installation, special technical performance, fixed location, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, less land occupation and environmental protection effect.
