Locking device for power transmission line detector

Abstract

The invention relates to a locking device for a power transmission line detector. The locking device comprises an upper-part shell and a lower-part shell, wherein the bottom part of the upper-part shell is provided with an upper concave opening, and the top part of the lower-part shell is provided with a lower concave opening; a clamping opening is arranged on the side wall of the front part of the lower-part shell; two opposite side ear plates are arranged on the side wall of the rear part of the lower-part shell; the rear part of the upper-part shell is hinged between the top parts of the two side ear plates by a second hinging shaft; a torsion spring is arranged on the second hinging shaft; a clamping hook is hinged at the front part of an inner cavity of the upper-part shell by a first hinging shaft; the front end of the clamping hook extends out of an opening at the front end of the upper-part shell; a base is arranged at the middle part of the inner cavity of the upper-part shell; a rotary base is hinged on the base; a pushing rod motor is fixed on the rotary base; a rotary connection block is arranged at the front end of a telescopic rod of the pushing rod motor; and the rotary connection block is hinged with the inner end of the clamping hook. The locking device also comprises a control circuit board, a battery and a Hall sensor, wherein the pushing rod motor, the battery and the Hall sensor are respectively and electrically connected with the control circuit board.

Description

technical field [0001] The invention belongs to the technical field of power fault detection, and in particular relates to a locking device for a power transmission line detector. Background technique [0002] As an important infrastructure for the national economy and the people's livelihood, power transmission lines are particularly important to ensure their safe operation. Due to natural factors and human factors, transmission lines usually have various faults, such as open circuit caused by disconnection of transmission line, short circuit of transmission line to ground, short circuit between phase lines, etc. It is very important to find and deal with the above faults in time . The existing fault indicators use the principle of current transformers, take the transmission line as the primary winding, install the annular iron core wound with the secondary winding on the indicator, detect the power supply of the line through the induced potential of the secondary winding,...
