Abstract

The invention relates to a high-voltage electroscope clamping hook. The clamping hook comprises a first hook arm, a second hook arm and an arc-shaped connecting piece; the upper end of the first hookarm is connected with one end of the arc-shaped connecting piece, and the other end of the arc-shaped connecting piece is connected with the second hook arm, so that the clamping hook is U-shaped; thefront face of the first hook arm and the front face of the second hook arm are oppositely arranged, and a guide groove is formed in the back face of the first hook arm in the vertical direction; anda connecting ring is arranged at the lower end of the first hook arm and communicated with the guide groove. An electroscope conductive head is fixed by arranging the connecting ring, and the contactarea of the clamping hook and the electroscope conductive head is increased by arranging the guide groove, so it is guaranteed that the electroscope result is more accurate and reliable.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a clip hook for a high voltage electroscope. Background technique [0002] In the operation and maintenance of power transmission and distribution lines, it is often necessary to change the line from the running state to the maintenance state. In order to ensure the safety of the operators, it is necessary to conduct an electrical inspection before adding the grounding wire. At present, the acousto-optic electroscope used in the power industry has the advantages of simple structure and convenient operation. However, in the actual operation process, the operator uses the current electrical inspection equipment to confirm that there is no voltage after the electrical inspection, and then connects the ground wire. There is obviously a certain time interval in this operation process, and the seamless connection cannot be truly achieved. The line may be electrified due to reverse power ...
