Live maintenance tool for outdoor isolating switch

Abstract

The invention discloses a live maintenance tool for an outdoor isolating switch. The live maintenance tool comprises a clamping tank frame, a driving mechanism, a driving element, a deformation pipe and an insulating rod, the clamping tank frame is in a U shape and used for installing a loosening agent liquid gas tank, an opening is formed in the top end of the clamping tank frame, the bottom pre-tightening device is arranged at the bottom end of the clamping tank frame, the driving mechanism is arranged on one side of the clamping tank frame and comprises a control device and a driving device, the driving device is installed above the control device and electrically connected with the control device, and the driving element is fixedly installed above the clamping tank frame. The driving device presses the loosening agent liquid gas tank nozzle through a driving element, the deformation pipe is arranged on the side, away from the clamping tank frame, of the driving mechanism, the bottom end of the deformation pipe is detachably and fixedly connected with the insulating rod, and a control button is arranged at the bottom end of the insulating rod and wirelessly connected with the control device. According to the invention, live maintenance of the transmission part of the disconnecting switch is realized, the power failure time and frequency are reduced, workers directly operate on the ground, and the high-altitude operation difficulty and safety risk are reduced.

Description

technical field [0001] The invention belongs to the field of power system maintenance, and in particular relates to a live maintenance tool for an outdoor isolating switch. Background technique [0002] The normal operation of the isolating switchgear in the substation depends largely on the contact resistance of the isolating switch contacts. The operation of the equipment is affected by the surrounding environment. After a period of time, the conductive surface of the isolating switch contact is corroded, and an oxide layer is formed on the surface, which increases the resistance of the contact. The contact is burnt out and needs to be replaced with a new isolating switch. [0003] In order to prevent the isolating switch from burning out, the equipment is usually powered off, and the isolating switch is maintained by manual maintenance to reduce the resistance. However, in actual work, it is very difficult to cut off the power of the equipment, and it is impossible to c...
