Abstract

The invention provides a remote control opening device of a cabinet type circuit breaker. The device is used for controlling opening of an opening coil in a circuit breaker cabinet and comprises a rack and a locking device which extends out of the rack and is fixedly connected to the circuit breaker cabinet. The rack is further provided with a switch connection device which is close to or far awayfrom the opening coil and makes the opening coil be disconnected, and a control box used for driving the switch connection device to act by a remote control module. After the rack is connected with the circuit breaker cabinet in a limiting mode, the control box is operated to enable the switch connection device to be close to the opening coil, an opening coil iron core is pressed to be disconnected, then the switch connection device is controlled to be away from the opening coil, and a locking device is detached to move the rack away. A disconnection device is arranged to perform disconnection control on the opening coil, an operator does not need to contact the opening coil, and after the disconnection device is connected with the circuit breaker cabinet, the opening coil can be controlled to be disconnected through the switch connection device so that a manual operation risk is reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a remote control opening device for a cabinet type circuit breaker. Background technique [0002] A circuit breaker refers to 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. [0003] 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. [0004] Circuit breakers are divided into cabinet-type circuit breakers and column-type circuit breakers. Cabinet-typ...
