Description

Technical field:

Its main function is to provide DC power to protection devices, operating mechanisms in electric high-voltage cabinets, circuit breaker switches, hydraulic gate operators, electrical and automation equipment, etc. It plays a very important role and has a great impact on the operation of the unit. Therefore, it is necessary to monitor the operating status of the DC panel at all times.

[0003] According to the maintenance regulations of the automated dispatching system, staff members need to inspect the site once a day.
