Embodiment Construction

[0050] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0051] The specific embodiment of the circuit breaker room interlocking device of the present invention: as figure 1 As shown, the switch cabinet includes a cabinet body 1, a cabinet door 2 and a circuit breaker room interlocking device. In this embodiment, unless otherwise specified, the cabinet door refers to the door of the circuit breaker room, and the cabinet door is located at the front side of the circuit breaker room. The circuit breaker room interlocking device includes a circuit breaker grounding switch interlocking device 3 . Such as figure 2 As shown, the grounding switch interlocking device 3 of the circuit breaker includes a grounding interlocking piece 31 that realizes the interlocking of the circuit breaker and the grounding switch. The locking piece 31 realizes the opening and closing of the grounding switch by moving left and right....

Abstract

The invention relates to the field of switch equipment, in particular to a circuit breaker chamber interlocking device. An interlocking mechanism of the circuit breaker chamber interlocking device comprises an interlocking rod, wherein a limitation piece sleeves the interlocking rod, a locking position and an unlocking position are arranged on a movable range of the limitation piece, the interlocking mechanism also comprises a cabinet door interlocking piece, the cabinet door interlocking piece is matched with the interlocking rod and leftwards and rightwards moves with the interlocking rod when a cabinet door is closed, so that the cabinet door is maintained locked when a grounding switch is broken, and the locking of the cabinet door can be eliminated when a circuit breaker is arranged at an experiment position. In the circuit breaker chamber interlocking device, interlocking of the cabinet door and the circuit breaker is achieved by the interlocking rod entering in and out of the interlocking piece of the circuit breaker and the cabinet door interlocking piece arranged on the interlocking rod, an original interlocking structure of the circuit breaker is not changed, and the problem of complexity of an existing circuit breaker chamber interlocking device structure of the switch cabinet is solved.

Description

technical field [0001] The invention relates to the field of switchgear, in particular to an interlocking device for a circuit breaker room. Background technique [0002] According to the five-proof requirements for medium voltage switchgear to prevent accidental entry into live compartments, during operation of 35kV medium voltage switchgear, it is necessary to control the interlocking control of the removable parts of the cabinet and the live compartment. There is a risk of straying into live compartments in the following operations: racking the circuit breaker when the switch cabinet door is not closed, opening the circuit breaker compartment door when the circuit breaker of the switch cabinet is in the working position. [0003] In the high-voltage switchgear in the current industry, an interlocking device is usually set to realize the interlocking between the grounding switch and the circuit breaker. The switch interlock mechanism includes a handcart propulsion mechani...
