Problems solved by technology

There are three commonly used methods. One is to use a ladder to hang the secondary current line, which is likely to cause maintenance personnel to fall from a high altitude when going up and down the ladder; but to use high-voltage insulating rods to hang the secondary current line, which may easily cause the high-voltage insulating rod to fall to the high-voltage live lines on both sides. , causing personal electric shock accidents; the third is to use the lift car to connect the lead wires of the current transformer, which is high in cost and low in efficiency

Description

technical field [0001] The invention relates to the technical field of high-altitude work safety appliances for electrical equipment, in particular to a current transformer working lead wire suspension device. Background technique [0002] In the field of high-voltage substation maintenance, especially during the maintenance of current transformers, the existing current transformers are installed outdoors. In order to test the polarity and volt-ampere characteristics of the current transformers, it is necessary to hang secondary line. There are three commonly used methods. One is to use a ladder to hang the secondary current line, which is likely to cause maintenance personnel to fall from a high altitude when going up and down the ladder; but to use a high-voltage insulating rod to hang the current secondary line, which may easily cause the high-voltage insulating rod to fall to the high-voltage live line on both sides. , causing personal electric shock accidents; the thir...
