Abstract

The invention discloses a dismantling structure of a line fault indicator for electric equipment, which comprises an insulating rod and a fault indicator mounting plate. The insulating rod is fixedly connected with a U-shaped rod, and the U-shaped rod is symmetrically rotatably connected with a sleeve shaft. , one side of the U-shaped bar is fixedly installed with a micro motor, the output end of the micro motor is fixedly connected with an output shaft, a transmission mechanism is provided between the output shaft and the sleeve shaft, and a A rectangular telescopic rod, the end of the rectangular telescopic rod far away from the sleeve shaft is fixedly connected with a magnetic block. The present invention drives the first sprocket to rotate quickly through a micro motor, so that the rectangular telescopic rod drives the magnetic block to perform rapid rotation, and the magnetic block and the magnetic head are engaged to drive the slide bar and the first limit bar to move between each other. Reverse rotation, the thread head starts to disengage from the thread groove until it is completely disengaged, completing the quick disassembly work, saving time and effort.

Description

technical field [0001] The invention relates to the technical field of line fault indicators, in particular to a dismantling structure and a dismantling method of a line fault indicator for electric equipment. Background technique [0002] Fault indicator refers to a device installed on power lines (overhead lines, cables and busbars) to indicate fault current. Most fault indicators can only identify and indicate short-circuit faults by detecting the characteristics of short-circuit current. Electromagnetic induction equipment that reflects a short-circuit current passing through and a fault sign (red card) appears. Install this fault indicator along the distribution line. Once the line fails and the short-circuit current flows, the fault indicator will act, and the red card of the fault sign will appear. Then patrol along the line, the fault indicators from the power supply side to the fault point all show red cards, and the fault indicators after the fault point do not sh...
