Circuit breaker equipment for instantaneous overload conditions

Abstract

The invention discloses circuit breaker equipment for an instantaneous overload state. The circuit breaker equipment comprises a circuit breaker shell and a protection device, four corners of the surface of the bottom end of the circuit breaker shell are in sliding connection with rolling wheels through universal shafts; an accommodating box is fixedly mounted on the upper side surface of the front end of the circuit breaker shell; a groove is chiseled in the surface of the upper side of the accommodating box; a treatment box is fixedly mounted on the right side of the lower end of the accommodating box; the middle surface of the upper end of the circuit breaker shell is fixedly connected with a display screen. The surface of the right end of the display screen is fixedly connected with asoft catheter; and the display screen is electrically connected with an alarm lamp on the left side through a wire, a standby power box is fixedly installed at the lower end of the left side in the protection device, a static contact is fixedly connected to the surface of the right end of the standby power box, a movable contact is fixedly installed at the right end of the static contact, and themovable contact is slidably connected with a sliding block groove through a sliding block. The circuit breaker equipment for the instantaneous overload state is reasonable and simple in structural design, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of circuit breaker equipment, in particular to a circuit breaker equipment used in an instantaneous overload state. Background technique [0002] A circuit breaker is a switching 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 according to their scope of use. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. It can automatically cut off the circuit when there is a fault, and its function is equivalent to the combination of a fuse switch and an overheating and underheating relay. [0003] In the technical solution provided by the patent document CN203707616U, the circuit breaker is raised by the suppor...
