Abstract

The invention provides a test line wiring tool with voltage monitoring and auxiliary storage functions. The test line wiring tool comprises an double-layer insulation mounting box, a hinge shaft vertically arranged in the middle of the double-layer insulation mounting box, a left insulation clamp body and a right insulation clamp body which are connected by the hinge shaft and arranged under the double-layer insulation mounting box, a voltage monitoring device fixedly arranged on the upper layer of the double-layer insulation mounting box, and an auxiliary storage device matched with the voltage monitoring device. The voltage monitoring device comprises a contact pin fixedly arranged on the upper layer of the double-layer insulation mounting box and located at the front end of the hinge shaft, a test wire interface fixedly connected with the tail end of the contact pin, a voltage induction indicating lamp fixedly connected with the middle of the contact pin, and a grounding wire connected with the voltage induction indicating lamp in series through a resistor. The auxiliary storage device comprises an insulated hose strap arranged at the tail end of the left insulation clamp body.The test line wiring tool has the characteristics of being capable of improving the working efficiency and guaranteeing the safety of the operation.

Description

technical field [0001] The invention specifically relates to a power operation and maintenance tool, in particular to a test line wiring tool with voltage monitoring and auxiliary storage functions. Background technique [0002] In order to ensure the safety of the grid and equipment and improve the reliability of the grid power supply, the equipment in the substation needs to be checked regularly. Relay protection devices and safety automatic devices are no exception. In addition, during the daily maintenance or overhaul of the secondary system, the devices also need to be calibrated. This requires us to use the test line to add the simulated fault voltage and current to the device through the terminal block. This is very common in the secondary maintenance work of substations. [0003] At this stage, for newer substations, AC terminal blocks are often used for the terminal blocks of the voltage and current loops, and the terminal blocks are equipped with test line jacks,...
