How To Avoid Hazards When Using High And Low Voltage Distribution Cabinets?

How to avoid hazards when using high and low voltage distribution cabinets?

High and low voltage distribution cabinets are relatively dangerous in many electrical facilities. Today, Taian Tengda Electrical Equipment will introduce how to avoid the dangers of using high and low voltage distribution cabinets.

High and low voltage distribution cabinets, as the name suggests, are distribution equipment used for power distribution, control, measurement, and connection of cables in the power supply system. Generally, high-voltage switchgear is used in power supply bureaus and distribution stations, and then led out from the low-voltage side of the transformer. The low-voltage distribution cabinet is then connected to various power distribution boards, control boxes, and switch boxes, where some switches, circuit breakers, fuses, buttons, indicator lights, instruments During the protection period of wires and other components, the distribution equipment that meets the design requirements is integrated. High and low voltage distribution cabinets are highly dangerous in many electrical facilities. Here, we introduce several preventive measures for high and low voltage distribution cabinets!

The preventive measures for high and low voltage distribution cabinets are divided into several aspects:

1. After the vacuum circuit breaker car inside the high-voltage distribution cabinet is closed at the experimental position, the car circuit breaker cannot enter the designated position. It is necessary to prevent the circuit breaker from closing under load.

When the grounding switch in the high-voltage distribution cabinet is in the closed position, the car circuit breaker cannot be closed. It is necessary to prevent the grounding wire from closing.

3. When the vacuum circuit breaker in the high-voltage distribution cabinet is closed, the mechanical connection on the grounding switch at the back door of the panel and cabinet is locked with the cabinet door to prevent accidental entry into the live compartment.

4. The vacuum circuit breaker inside the high-voltage distribution cabinet cannot exit the position of the car circuit breaker during working and closing operation, to prevent the loaded knife switch from being pulled.

5. The vacuum circuit breaker inside the high-voltage distribution cabinet is closed during operation, and the grounding switch cannot be put into operation. Prevent live hanging of grounding wires.

The area around the high and low voltage distribution cabinets should also be well protected, and people should not enter casually, causing danger. At the same time, maintenance personnel should always pay attention to their own operations and ensure their own safety
