Abstract

The invention provides a telescopic sleeve safety protection device for power wire and cable heads. The device is convenient to disassemble and assemble and small in occupied space; after a terminal is loosened, a movable sleeve automatically pops up, insulated isolation with a metal electrified part and insulation with the outside can be automatically achieved, the time of an insulated isolationprocess is extremely short, and electric shock of workers is prevented. Once the device is installed, the device does not need to be disassembled, and the device is convenient to use, can be used fora long time in an electrified mode, is easy to operate, cannot cause electric shock of workers in the operation process or cause short circuit or grounding of cables, does not need insulation wrappingin the overhaul and maintenance processes of cables, and has high operation and maintenance efficiency. With the device, the problems of electric shock of workers and short circuit or grounding of cable loops easily caused in the disassembly and connection operation of existing electrified cables are avoided, and the efficiency of finding faults of equipment and devices due to open circuit of a secondary loop of the equipment caused by terminal wiring looseness is effectively improved.

Description

technical field [0001] The present application relates to the technical field of wire and cable wiring installation, in particular to a safety protection device for electric wire and cable head telescopic sleeves. Background technique [0002] Power cables are the most important equipment for power transmission and transmission. The most common work in the maintenance and repair of power equipment is to disconnect and connect cables. During the work, there is a risk of electric shock for workers who touch the metal transmission medium of the cables. ; In addition, because the short circuit or grounding of the power cable circuit is likely to cause equipment failure and cause fires due to equipment insulation damage, it is not allowed to cause short circuit or grounding of the AC and DC circuits during the work. [0003] During the repair and maintenance of power cable equipment, the most common treatment method for exposed metal parts is to wrap the exposed cable core with i...
