Description

Moving contact assembly of isolating switch Technical Field The application relates to the field of isolating switches, in particular to a moving contact assembly of an isolating switch. Background An isolating switch is an electrical device, which is mainly used for isolating a circuit in an electrical system to ensure the safety of equipment and personnel. The movable contact is a movable contact part in the isolating switch, and the movable contact is driven by the operating mechanism to contact or separate from the fixed contact, so that the on-off of a circuit is realized. The existing isolating switch mainly comprises a shell, a rotating shaft, a fixed seat, a moving contact and a fixed contact. The fixed contact is fixedly arranged on the shell, the moving contact is arranged on the fixed seat, and the rotating shaft penetrates through the fixed seat and is connected with the shell. Through rotating the rotating shaft, the fixed seat and the moving contact can be driven to rotate, and then the switching-on and switching-off operation between the moving contact and the fixed contact is realized, so that the on-off control of a circuit is completed. In the prior art, the moving contact and the rotating shaft are connected through the fixing seat, and the moving contact is arranged on the fixing seat, so that when a certain moving contact is damaged, the moving contact is inconvenient to replace quickly, and the installation and replacement efficiency of the moving contact can be affected.
