Safe-operation intelligent interlocking device for high-voltage cabinet

Abstract

The invention discloses a safe-operation intelligent interlocking device for a high-voltage cabinet, and the device comprises a cabinet body disposed above the horizontal ground, the side wall of the upper end of the cabinet body is in shaft connection with a first operation shaft which is used for controlling a circuit breaker, and the outer side of the first operation shaft is in key connection with a first gear; the system further comprises; the second operating shaft is in shaft connection with the side wall of the cabinet body and is used for controlling an isolating switch and a grounding switch, and the outer side of the second operating shaft is in key connection with a second gear; the second crank arm is fixedly mounted on the outer side of the second operating shaft; and the positioning rod is movably arranged in the side wall of the cabinet body and is used for positioning the second operation shaft so as to avoid misoperation in the maintenance process. According to the intelligent interlocking device for the high-voltage cabinet capable of being safely operated, effective interlocking can be carried out on multiple pieces of electric control equipment, it is ensured that a worker can carry out standard operation, the safety in the follow-up maintenance process is effectively improved, and accidents caused by misoperation in the maintenance process can be prevented.

Description

technical field [0001] The invention relates to the technical field of high-voltage cabinets, in particular to a safe-operable intelligent interlocking device for high-voltage cabinets. Background technique [0002] High-voltage switchgear refers to electrical products used for power generation, transmission, distribution, or protection in power systems. It contains a large number of electrical control equipment, such as circuit breakers, isolating switches, and grounding switches. During the use of high-voltage cabinets, it is necessary to The interlocking device is used to realize the interlocking of various equipment inside the cabinet, so as to avoid electric accidents caused by misoperation, but there are still some shortcomings in the existing intelligent interlocking devices for high-voltage cabinets. [0003] For example, a high-voltage switchgear with a publication number of CN108155039A has a five-proof mechanical locking and interlocking device, which can prevent ...
