An insulation device applied to prevent ground faults in electric power field

Abstract

The invention discloses an insulating device for preventing a grounding fault in an electric power field. The insulating device includes a first insulating rod, a second insulating rod and a third insulating rod. The first insulating rod is provided with a first circular chamber. Four fixed cross bars are equidistantly welded onto the top of the sidewall of the first circular chamber. A motor is fixed to the bottom inner wall of the first circular chamber. A screw rod is welded onto the output shaft of the motor. The second insulating rod is placed inside the first circular chamber. The second insulating rod is provided with a second circular chamber. A first arc rack meshed with the screw rod is arranged on the sidewall of the second circular chamber. The third insulating rod can be easily installed and disassembled inside a mounting tube. The distance between the bottom of the first insulating rod and top of the second insulating rod can be changed, which enables a sensor on the third insulating rod to slide on a transmission line for detection. It is convenient for electrical maintenance personnel to use the insulating device.

Description

technical field [0001] The invention relates to the technical field of power supply and utilization, in particular to an insulation device applied to prevent grounding faults at electric power sites. Background technique [0002] In the 10kV distribution network work site, once a line grounding fault occurs, the staff must ensure that the distance from the grounding point is at least 4 meters indoors and 8 meters outdoors according to safety requirements. Electric shock caused by insufficient distance. Therefore, in the field where the fault is found, it is necessary to use the insulation device for preventing ground fault in the power field to find and locate the fault point. The insulating rods include two insulating rods of the same specification and the insulating rods installed with sensors. Since the installation distance between the two insulating rods of the same The installation distance is adjusted, and it is inconvenient to install the insulating rod with the se...

[0002] In the 10kV distribution network work site, once a line grounding fault occurs, the staff must ensure that the distance from the grounding point is at least 4 meters indoors and 8 meters outdoors according to safety requirements. Electric shock caused by insufficient distance

Therefore, in the field where the fault is found, it is necessary to use the insulation device for preventing ground fault in the power field to find and locate the fault point. The insulating rods include two insulating rods of the same specification and the insulating rods installed with sensors. Since the installation distance between the two insulating rods of the same The installation distance is adjusted, and the insulating rod with the sensor installed is inconvenient to install on the corresponding fixing piece
