Electricity testing auxiliary device and system applied to 10/20kV overhead line

Abstract

The invention discloses an electricity testing auxiliary device and system applied to a 10 / 20kV overhead line. The electricity testing auxiliary device comprises an electricity testing pen installation cylinder, an insulation rod installation cylinder and a positioning buckle; the diameter of each of the electricity testing pen installation cylinder and the insulation rod installation cylinder isgradually increased from one end part to the other end part; the outer side wall of the electricity testing pen installation cylinder is connected with the outer side wall of the insulation rod installation cylinder; a first electricity testing pen inserting hole, a second electricity testing pen inserting hole and a third electricity testing pen inserting hole which are connected in sequence areformed in the electricity testing pen installation cylinder; an insulation rod inserting hole is formed in the insulation rod installation cylinder; the diameter of the insulation rod inserting hole is gradually increased from one end to the other end; the positioning buckle is arranged on a side wall of the electricity testing pen installation cylinder; the positioning buckle is arranged close toone end, which is relatively small in diameter, of the insulation rod inserting hole; and the positioning buckle partially covers the insulation rod inserting hole. The electricity testing auxiliarydevice is used cooperatively with a 10 / 20kV electricity testing pen and a 110 / 220kV insulation rod, and is relatively good in operation convenience and relatively high in safety.

Description

technical field [0001] The invention relates to the technical field of electrical inspection assistance, in particular to an electrical inspection auxiliary device and system applied to 10 / 20 kV overhead lines.

[0002] The distribution network operation often needs to be tested on the 10kV / 20k pole tower. Generally, the total length of the 10 / 20kV electroscope pen is about 1.2 meters. Measuring live state of overhead line conductors

In order to meet the needs of the electric test operation under the tower, it is usually necessary to bundle the 110 / 220kV insulating rod and the 10 / 20kV test pen together for measurement, such as Figure 5 As shown, this method is neither safe nor compliant, and there are many security risks in such a bundling

On the one hand, the binding is done manually, and it is difficult to ensure the firmness

On the other hand, the binding method usually uses sticky tape for binding. In this way, after use, the sticky glue remains on the 110 / 220kV insulating rod, making the surface of the 110 / 220kV insulating rod dirty. The sticky glue has a certain conductivity, which will cause Reduce the insulation effect; and after use, the 10 / 20kV electric test pen holder also remains viscous colloid, which makes the surface dirty and reduces the insulation strength. It directly threatens the personal safety of the electric test personnel during the non-pole and tower electric test, making the safety poor

In addition, the existing bundling method is relatively complicated and the operation convenience is poor
