Description

A plug-in live display holder for high-voltage switch cabinets in substations

Technical field

The invention relates to the field of electric power equipment, specifically a plug-in live display holder for a high-voltage switch cabinet in a substation.

Background technique

The high-voltage switch cabinet is a kind of electrical equipment. The external lines of the high-voltage switch cabinet first enter the main control switch in the cabinet, and then enter the sub-control switch. Each branch circuit is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc. Some also have high-voltage chamber and low-voltage chamber switch cabinets and high-voltage busbars, such as power plants, etc. Some also have low-cycle circuits to protect the main equipment. Load-reduction high-voltage switchgear is usually equipped with a live indicator, mainly to check whether the line side is live and prevent workers from entering the live interval by mistake; the grounding knife gate and the locking function of the switch cabinet rear cabinet door are realized through internal nodes, and the live indicator Installation requires the use of a powered monitor stand.

Most of the existing live display stands are installed inside the high-voltage switch cabinet through bolts. This connection method makes the installation and disassembly of the live display stand troublesome and time-consuming, and it is not convenient to use. Moreover, the live display stand is set inside the high-voltage switch cabinet. When the live display needs to be replaced and installed, the cabinet door must be opened, the live display must be removed from the inside of the cabinet door, and the faulty live display must be replaced. However, if the cabinet door is opened without a power outage, a large number of secondary batteries will be distributed inside the cabinet door. Loop wiring, dense lines and numerous equipments have resulted in a small range of activities for the staff and limited vision. It is easy to accidentally touch other lines and equipment in the switch cabinet, which poses a considerable safety hazard and is also harmful to the staff. There is little mental pressure, so the current installation and maintenance work of traditional live displays has considerable safety hazards and work efficiency is not high.
