Switch cabinet system based on wireless energy harvesting operating mechanism

Abstract

The invention relates to a wireless energy-taking operating mechanism-based switch cabinet system. The wireless energy-taking operating mechanism-based switch cabinet system comprises a wireless energy-taking isolating switch, a wireless energy-taking circuit breaker and a wireless energy-taking quick grounding switch which are arranged in the switch cabinet and are connected sequentially, wherein the wireless energy-taking isolating switch is also connected to an inlet wire of the switch cabinet; the wireless energy-taking circuit breaker is also connected to an outlet wire of the switch cabinet; the wireless energy-taking quick grounding switch is also connected with a grounding wire. The wireless energy-taking operating mechanism-based switch cabinet system also comprises a wireless electric energy emitting device which is arranged outside the switch cabinet and is used for controlling the wireless energy-taking isolating switch, the wireless energy-taking circuit breaker and the wireless energy-taking quick grounding switch. The wireless energy-taking operating mechanism-based switch cabinet system can realize electrical isolation of an external wireless power supply part and electric appliances in the switch cabinet, so that the inspection operation of the switch cabinet is simplified, the possibility and the hazardous degree of electric shock are reduced, accidents, such as electric shock and the like, are avoided well, and the switch cabinet system is more convenient and safer to operate.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, and in particular relates to a switch cabinet system based on a wireless energy-taking operating mechanism. Background technique [0002] The switchgear is the key equipment widely used in the field of power distribution at present. The quality of the switchgear is directly related to the power supply safety and power supply quality of the power distribution system. At present, the main operation mode of the switchgear system is manual operation. Factors such as the professional quality, safety awareness of the operators, and the insulation performance of the switchgear will affect the safety and reliability of the operation. The all-electric operation of the switchgear is an important prerequisite for the programmed operation of the substation in the future. At present, the all-electric operation of the switchgear is mainly driven by the motor, but the motor is prone to stalling an...

AI Technical Summary

Problems solved by technology

The traditional isolating switch relies on the motor operating mechanism or manual operation to realize the opening and closing operation, the operation control process is cumbersome and the stability is poor

Circuit breakers widely exist in high and low voltage power lines, which can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Traditional circuit breakers Generally, spring or electromagnetic mechanisms are used. There are permanent magnet mechanisms in the medium-voltage field. The engineering application is relatively mature, but there is also the problem of excessive movement dispersion.
