Abstract

The invention provides a current induction device. The current induction device comprises a current clamp and a current clamp wrench which is arranged on the side wall of the current clamp and controls opening and closing of the current clamp, wherein one side of the current clamp is connected with a hollow insulating rod; a power supply, an electric push rod and a control module for controlling the electric push rod to stretch out and draw back are arranged in the insulating rod; a push rod of the electric push rod is connected with the current clamp wrench by means of a traction piece; and the power supply is electrically connected with the electric push rod by means of the control module. The current induction device achieve the effect of directly installing the current clamp at a corresponding test position on the ground, does not require any high-altitude operation in the whole test process, has no connecting cable, and realizes the purpose of zero-risk safety measurement.

Description

technical field [0001] The invention relates to the field of current induction testing, and more particularly, to a current induction device. Background technique [0002] In order to reduce reactive power loss, the power system usually adopts the method of parallel compensation capacitor bank to improve the power factor. In order to meet the requirements of automatic tracking and real-time compensation of the power system, the reactive power compensation device must frequently switch and cut reactive power compensation capacitors. group, and the switching and switching operations of the capacitor group will generate current and overvoltage shocks, causing capacitor damage. In order to ensure the normal operation of the equipment, capacitors need to be tested regularly, and it is very important to find capacitor defects early and avoid fault expansion. The installation height of the capacitors of the capacitor bank is generally high, some as high as 4 to 5 meters. The test ...
