Abstract

The invention discloses a vacuum circuit breaker for a switch cabinet, and relates to the technical field of power distribution equipment. The vacuum circuit breaker comprises a protection box and a circuit breaker body, wherein a dustproof frame is movably arranged in the protection box, the circuit breaker body is located in a space formed by the protection box and the dustproof frame, a fixingbox is fixedly arranged on the surface of the protection box, and an abutting frame abutting against the dustproof frame is movably connected to the interior of the protection box. By arranging an operation block to rotate, the operation block can drive an upper movable shaft to rotate, so that the upper movable shaft can drive two positioning rods to rotate clockwise at the same time through a transmission belt, the front end of a dustproof frame can be ejected out of a protection box by an abutting frame, a worker can conveniently take down the dustproof frame and clean and replace the dustproof net, the effect of convenient cleaning and replacement is achieved, and the situation that circulation between air in the protection box and outside air is affected due to the fact that the dustproof net is blocked by dust is avoided.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a vacuum circuit breaker for a switch cabinet. Background technique [0002] With the continuous development of the national economy, the grid structure and load characteristics are becoming more and more complex. In order to protect equipment and personal safety, higher requirements are put forward for the safety and reliability of power supply. The most common circuit safety device is a circuit breaker, which is a It is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload and short circuit. [0003] In the prior art, vacuum circuit breakers are generally located outdoors. In order to prevent solid particles in the outside air from entering the circuit breaker and slowly accumulating to cause a short circuit, dust-proof nets are installed on the outside of the...
