Armored movable alternating-current metal switch equipment

Abstract

The invention discloses armored movable alternating-current metal switch equipment, relates to the related field of switch cabinet equipment, and aims to pull out a circuit breaker handcart from a handcart chamber when the circuit breaker handcart is operated, increase the operation space, improve the efficiency, monitor the use environment and give an alarm in time when the use exceeds the limit.Convenience is brought to workers to take measures. A cover plate is arranged above a switch equipment cabinet shell, a partition plate is arranged in the switch equipment cabinet shell, a bus chamber, an instrument chamber, a handcart chamber and a cable chamber are arranged between the switch equipment cabinet shell and the partition plate, and an instrument door, a handcart door and a cable door are arranged on one side of the instrument chamber, one side of the handcart chamber and one side of the cable chamber respectively. The other side of the bus chamber and the other side of the cable chamber are respectively provided with an overhaul cabinet door, one side of the instrument door, one side of the handcart door, one side of the cable door and one side of each overhaul cabinet doorare respectively provided with a locking bolt, and the locking bolts are in threaded connection with the switch equipment cabinet shell.

Description

technical field [0001] The invention belongs to the technical field of switchgear, in particular to an armored removable AC metal switchgear. Background technique [0002] Armored removable AC metal switchgear is suitable for three-phase AC 50Hz, 40.5kV single busbar and single busbar segmental power system, mainly used in power transformation and distribution systems of power plants, substations, industrial and mining enterprises, and high-rise buildings. It is used to receive and distribute electric energy, and to control, protect and monitor the circuit. It can be equipped with microcomputer intelligent protection to realize telemetry, remote control, remote signaling and unattended. And has a perfect "five defenses" function. The layout of components is reasonable, the scheme is complete, and the scalability is strong. It is an ideal new power distribution device. [0003] With the continuous improvement of electricity demand, the difficulty of using traditional switch...

AI Technical Summary

Problems solved by technology

[0003] With the continuous improvement of electricity demand, the difficulty of using traditional switchgear for snow distribution management is greatly increased, and it cannot meet the diversified power distribution needs. The adaptability of the existing armored removable AC metal switchgear is strong. , can meet a variety of different needs, greatly improve the power distribution demand, and greatly improve the safety performance of power consumption

[0004] The internal structure of the armored removable AC metal switchgear is complex, and the internal electrical components are relatively sensitive. When the staff operates the handcart of the circuit breaker, due to the narrow operating space inside the handcart room, the operation becomes more difficult. , and the switchgear cabinet has high requirements on temperature and humidity during use, the actual environment is easy to exceed the standard during use, and failure to take timely measures will result in poor use of the switchgear cabinet
