Abstract

The invention belongs to the technical field of isolating switches, and discloses a device for manually operating an isolating switch. The device comprises a rotating structure, a positioning structure, and a supporting structure. The rotating structure comprises a rotating shaft and a connecting rod, the connecting rod is arranged at one end of the rotating shaft and is used for connecting an isolating switch mechanism box, and the other end of the rotating shaft is connected with a driving mechanism; the positioning structure comprises a fixing sleeve, and the rotating shaft is coaxially arranged in the fixing sleeve; the supporting structure comprises a plurality of supports hinged to the outer wall of the fixing sleeve, and the supports are arranged to be of a telescopic structure. According to the device for manually operating the isolating switch, manual operation is replaced by an electric operation mode, so that the operation efficiency and the operation safety performance aregreatly improved.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to a device for manual operation of isolating switches. Background technique [0002] The isolating switch is an important high-voltage switching device in the power system. Its function is to disconnect the circuit with small load current on the one hand, and reliably isolate the electrical equipment that needs to be repaired from the live part of the power grid, so that the electrical equipment to be repaired and the power supply are clearly separated. In order to ensure the safety of maintenance work; on the other hand, switching operation can be performed to change the operation mode. For example, in the double bus operation mode, the isolation switch can be used to switch equipment or lines from one bus to another. Group bus goes up. [0003] At present, high-voltage disconnectors of 35kV and above are generally equipped with electric operating mechanisms, which are...
