Problems solved by technology
The existing power fault indicator overhead line branch device has a single function. Although there is an indication when the line fails, it is difficult to judge the type of fault; when a fault occurs, manual identification is still required, which is time-consuming and laborious
The overhead line current signal acquisition device is powered by a small solar panel, and the power supply is insufficient, and the solar panel cannot supply power normally in rainy or smoggy weather
The CT (current transformer) magnetic circuit of the overhead line current signal acquisition device only relies on the weak magnetic metal bracket with a very thin diameter to fix the signal. The magnetic field is weak and the acquisition accuracy is very poor.

The invention relates to a line fault detection device, in particular to a high-performance power fault indicator overhead line branching device. The high-performance power fault indicator overhead line branching device comprises an upper shell, a lower shell, an outer spring, an inner spring, a first screw, a second screw, a support, an antenna and two semicircular magnet coils, wherein the outer spring is fixed to the first screw, the force of the outer spring acts on the upper shell and the lower shell, and thus the upper shell and the lower shell are made to be tightly attached together; the support is fixed to the lower shell through screws, the inner spring is fixed to the support through the second screw, the antenna is arranged on the bottom of a cavity of the lower shell, and the two semicircular magnet coils are symmetrically mounted in a cavity of the upper shell and the cavity of the lower shell. According to the high-performance power fault indicator overhead line branching device, the tight pressing effect of the inner spring and the tight pressing effect of the outer spring are utilized, and mounting is more convenient; the antenna has a wireless communication function and can remotely transmit signals to working personnel.
Description
technical field [0001] The invention relates to the technical field of line fault detection devices, in particular to an overhead line branch device for a high-performance power fault indicator. Background technique [0002] Overhead high-voltage lines are often affected by grounding or short-circuit faults, which cause power outages and interruptions on the lines, seriously affecting normal power transmission and grid safety. Therefore, when a fault occurs on the line, it is necessary to quickly determine the fault point to eliminate the fault. The existing power fault indicator overhead line branch device has a single function. Although there is an indication when the line fails, it is difficult to judge the type of fault; when a fault occurs, manual identification is still required, which is time-consuming and laborious. The overhead line current signal acquisition device is powered by a small solar panel, and the power supply is insufficient, and the solar panel cannot ...
