Electric power automation switch cabinet

Abstract

The invention discloses an electric power automatic switch cabinet, and particularly relates to the field of switch cabinets, the electric power automatic switch cabinet comprises a cabinet body, a switch cabinet element assembly and a first surge protector, a lithium battery is fixedly installed at the bottom of an inner cavity of the cabinet body, and the input end of the lithium battery is electrically connected with the output end of the first surge protector; the output end of the lithium battery is electrically connected with a fusing control piece; the fusing control piece comprises a box body, a fusing metal block is fixedly installed on one side of an inner cavity of the box body, and a bolt base is fixedly installed at the other end of the fusing metal block. When the first surge protector is in a non-resistance or low-resistance state due to long-term use and breakdown damage, the driving motor is started, so that the second magnet rotates to be in a state shown in an attached drawing of the specification, and the magnetic induction lines of the magnetic pole pieces of the second magnet and the first magnet attract the magnetic sleeve head; therefore, the second surge protector replaces the first surge protector to form a new surge protection state, the whole maintenance difficulty is reduced, and the timeliness is high.

Description

technical field [0001] The present invention relates to the technical field of switch cabinets, and more particularly, to an electric power automation switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, surge protectors, etc., and some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. Low cycle load shedding for major equipment.

AI Technical Summary

Problems solved by technology

[0003] When a peak current or voltage suddenly occurs in the electrical circuit or communication line due to external interference, the combined fuse surge protector can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit. Effectively avoid unnecessary economic losses, but the existing fuse combination surge protectors still have some disadvantages in actual use, such as fuses are fixed inside or outside the surge protector, when the fuse plays a role and blows After that, the current surge protector cannot be used again, and will be discarded together with the surge protector, which causes a huge waste of resources, and at the same time, the fuse in the existing surge protector is easy to cause Electric sparks, which will cause the partial structure of the surge protector to melt or even catch fire, which is less safe

[0004] And once the surge protector is damaged, the entire switchgear system will lose current interference protection. The existing monitoring equipment cannot monitor the surge protector in real time because it cannot be connected to the surge protector. The self-protection monitoring equipment lacks timeliness, and once damaged, it will be irreparable
