Switch cabinet with mis-closing prevention function

Abstract

The invention discloses a switch cabinet with a mis-closing prevention function, which relates to the field of electric power engineering and comprises a cabinet body, a cabinet door is connected to the outer surface of the cabinet body, six insulators are connected to the upper portions of the two sides of the cabinet body respectively, a live detection circuit is installed on one side of the interior of the cabinet body, and a mis-locking lock is installed on the other side of the interior of the cabinet body. A plurality of wiring boards are installed in the cabinet body, ventilation cabinets are connected to the two sides of the cabinet body, and ventilation boards are connected to one sides of the two ventilation cabinets. Through a guide frame, an electromagnet, a sealing plug, a wind shield, a sealing ring, a telescopic rod, a spring and a self-operated pressure regulating valve, airflow is guided through the guide frame and a slope on one side in the ventilation cabinet in daily use, and the influence of a wind resistance reducing structure on the airflow is reduced; and meanwhile, by arranging the wind shield, airflow is prevented from entering the area between the sealing plug and the guide frame to apply pressure to the sealing plug, and the influence of high-temperature and high-pressure gas leakage on surrounding personnel and facilities is effectively avoided.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to a switch cabinet with a function of preventing false closing. 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 sub-circuit is set according to its needs, such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., switch There is a mechanical anti-misoperation device between the switch in the cabinet and the grounding knife, that is, anti-misoperation locking, so as to avoid the impact of the electric closing of the grounding knife on the circuit. [0003] The existing switchgear with the function of preventing accidental closing is due to the fact that there are many internal circuits and power facilities and the space is crowded, resulting in a large amount of shor...

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide a switchgear with anti-mis-close function to solve the technical problem that high-temperature and high-pressure gas leaks through the ventilation plate and threatens surrounding personnel facilities, and the dust-proof net and ventilation plate are easily covered by dust and cause blockage.
