Description

Technical Field

[0001] The invention belongs to the technical field of trolley type circuit breakers, and in particular relates to an emergency opening and closing remote control device for a trolley type circuit breaker. Background Art

[0002] Some of the existing trolley-type circuit breaker emergency opening and closing devices are built into high-voltage switch cabinets, with relatively complex structures. Each switch cabinet needs to be equipped with them, which is costly and cannot be operated remotely. When the switch equipment malfunctions, it will cause harm to on-site workers and even threaten their lives. There are also some emergency opening and closing devices that can operate circuit breakers remotely. Although the distance between the workers and the equipment is increased, the control device cannot control the force and speed of the opening and closing of the electric actuator. Excessive force will cause damage to the opening and closing buttons; too fast a return speed will cause unsuccessful opening and closing; in addition, the control device and the electric actuator are connected by soft wires, which restricts the direction and space of remote operation. Manual remote monitoring is required during operation, and the safety hazards to on-site workers cannot be eliminated; therefore, it is very necessary to provide a trolley-type circuit breaker emergency opening and closing remote control device with accurate positioning, remote operation, flexible use, safety and reliability.
