Abstract

The invention is applicable to the technical field of circuit breakers, and provides a circuit breaker installation protection structure, comprising a protective box with an open front, a containing box with an open top is fixedly connected to the bottom of the protective box, and an inner cavity of the protective box is The upper part is detachably provided with a circuit breaker body, and both sides of the circuit breaker body are fixedly connected with clips. The installation and protection structure of the circuit breaker is fixed by the clamping slot to the limit of the clamping strip, and the circuit breaker body is placed in the inner cavity of the protective box, and then the opening of the front of the protective box is closed by manually rotating the closed box door, and the circuit breaker body is installed. Protection, after closing, manually rotate the rotating lever by turning the handle, and drive the rack plate to rise through the rotation of the gear roller, so that the rack plate is inserted into the interior of the bayonet, and the strip is fixed in the interior of the slot to break the circuit. The device body is installed and fixed in the inner cavity of the protective box, the operation is simple and fast, and the time consumption is short.

Description

technical field [0001] The invention belongs to the technical field of circuit breakers, and in particular relates to an installation protection structure of a circuit breaker. Background technique [0002] A circuit breaker refers to a switch device that 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. Circuit breakers are divided into High-voltage circuit breakers and low-voltage circuit breakers, the distinction between high and low voltage is relatively vague, generally referred to as high-voltage electrical appliances above 3kV. [0003] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power supply lines and motors. When they have serious overload or short-circuit and under-voltage faults, they can automatically cut off the circuit. Its function is equivalent to a fuse switch. In combination w...
