An emergency opening device for electric equipment

Abstract

The embodiment of the invention discloses an emergency opening device for electric equipment, which includes a side-opening electrical control cabinet installed with a circuit breaker, and a flat-shaped fixing frame is installed on the inner side of the door of the electrical control cabinet. The upper rotation is connected with a swing arm, and one end of the swing arm is provided with a trigger device that slides down to press the switch handle of the circuit breaker. One end of the rod is connected with a rotating and telescopic mechanism that controls the up and down movement of the trigger device through positive and negative rotation, and a knob that is movably engaged with the splicing conductive rod and extended to the outside of the cabinet door is installed inside the said flat-shaped fixing frame. By installing a matching knob on the inner side of the cabinet door to make a structure that cooperates with the pull-down action of the switch handle of the air circuit breaker, when the equipment needs to stop in an emergency, there is no need to open the electric cabinet for operation, only need to twist the knob installed on the cabinet door to achieve The purpose of pulling the brakes.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of emergency opening devices, in particular to an emergency opening device for electric equipment. Background technique [0002] The circuit breaker is a kind of electrical appliance with a large amount of use and a wide range. It is an emergency opening device that can break the current under abnormal circuit conditions. Among them, the air circuit breaker is a low-voltage circuit breaker that is widely used in circuit breakers. It is a very important electrical appliance in the low-voltage power distribution network and electric drive system, and the general air circuit breaker is opened by pulling down the switch handle to a certain distance, and the air circuit breaker can be automatically opened, which has high practicability. [0003] In the prior art, for example, an emergency opening device whose notification number is CN106252146A is characterized in that, by pressing a button ...
