A high-voltage ring network cabinet with an internal protection device

Abstract

The invention discloses a high-voltage ring network cabinet with an internal protection device, comprising a cabinet body, a top cover is movably installed on the top of the cabinet body, a fire extinguisher box is installed on the top of the top cover, and smoke is installed on the bottom of the top cover A detector, and both sides of the bottom of the top cover are connected with discharge pipes. The smoke detector at the bottom of the top cover can detect the smoke and send out an alarm signal to notify the staff and the background control system. The background control system opens the solenoid valve inside the discharge pipe, and the fire extinguishing material inside the fire extinguisher box enters from the discharge pipe to the conveying pipe. The inside of the cabinet is then sprayed to the inside of the cabinet through the conveying pipe, and the fire extinguishing material can deal with the internal fire in time, which can avoid the spread of the fire and reduce the loss. When dealing with a fire, the staff can start the electric telescopic column to extend upward, lift the top cover off the cabinet, and the upper part of the cabinet is connected to the outside world. The staff can spray fire-extinguishing materials into the cabinet from the upper part to further extinguish the fire , to improve the efficiency of fire extinguishing.

Description

technical field [0001] The invention relates to a high-voltage ring network cabinet, in particular to a high-voltage ring network cabinet with an internal protection device, and belongs to the application field of high-voltage ring network cabinets. Background technique [0002] The high-voltage ring network cabinet is to improve the reliability of power supply, so that users can obtain power from two directions, and usually connect the power supply network into a ring. This power supply method is referred to as the ring network power supply. In the AC 10KV power distribution system such as ports and high-rise buildings, due to the small load capacity, the high-voltage circuit is usually controlled by a load switch or a vacuum contactor, and is equipped with a high-voltage fuse for protection. [0003] However, the existing high-voltage ring network cabinets still have certain deficiencies in use. The existing high-voltage ring main unit has a simple structure, low safety ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-voltage ring network cabinet with an internal protection device, which can solve the problem that the existing high-voltage ring network cabinet has simple structure, low safety performance during use, insufficient internal protection device, and fire in the internal circuit during use. not processed in a timely manner

The electrical accessories cannot be disassembled and installed separately, and the installation and replacement need to be disassembled as a whole, which is time-consuming and laborious, and the work efficiency is low

When disassembling, the internal circuits need to be disassembled and installed again, which is troublesome, and the various circuits cannot be quickly installed and disassembled, which is a technical problem with relatively large limitations.
