Abstract

The invention discloses an indoor high-voltage isolating switch interlocking device, which comprises an operating handle, a sliding shaft, an opening / closing indication board, an output shaft, a compressed spring and a positioning actuating mechanism, wherein the sliding shaft is arranged in the output shaft, one end of the sliding shaft is pressed against the bottom of a tail hole of the operating handle, the tail hole is provided with a lock core, and the other end of the sliding shaft is pressed against one end of the compressed spring; one end of a positioning cross pin penetrates through the output shaft and then is fixed in the middle of the sliding shaft; the positioning actuating mechanism comprises a positioning plate, a fixing plate, a voice prompt and switch on / off block outside the fixing plate, which are arranged in parallel; the positioning plate and the fixing plate are horizontally connected to form a positioning frame through a plurality of fasteners; the other end of the positioning cross pin is embedded on the positioning plate; and the other end of the output shaft penetrates through the positioning actuating mechanism and is fixedly connected with one end of the switch on / off block. The indoor high-voltage isolating switch interlocking device is compact, safe and reliable in structure, and simple and convenient to operate; and moreover, an error on / off accident of uncompleted interlocking of the isolating switch is avoided, and safety control is provided for operators and switchgear cubicles for loop network.

Description

technical field [0001] The invention relates to a safety operation device for an indoor high-voltage switchgear, in particular to a safety interlock device for the operation of an indoor high-voltage isolating switch, and belongs to the technical field of high-voltage electrical auxiliary equipment. Background technique [0002] The ring network power supply has the advantages of good flexibility and high reliability. It can avoid large-scale power outages caused by failures of cables, transformers and low-voltage equipment during single-network power supply, and can ensure continuous power supply to users to the greatest extent. Power supply requirements. The terminal equipment of ring network power supply mainly includes SF 6 Ring network switchgear and vacuum ring network switchgear, the high-voltage isolating switch supporting these two types of equipment mainly includes SF 6 Gas-filled switch disconnectors, connecting rod two-pole transmission disconnectors and ordin...
