Description

High voltage insulation hanging rod for DC high voltage test of line arrester

technical field

The utility model relates to the field of high-voltage line testing, in particular to a high-voltage insulation hanging rod used for direct-current high-voltage testing of line lightning arresters.

Background technique

At present, when conducting electrical tests on power equipment, it often involves connecting wires to them, such as transformer bushing or winding dielectric loss tests, lightning arrester DC leakage current tests, etc. And the existing tying line mode generally adopts the mode of manual climbing and articulated by hand, but in the field test, it often causes operational obstacles because of high equipment and reasons such as climbing danger. For example, the bushing of a 66kV and above transformer has a large inclination to the vertical direction, and the length of the bushing body is too long. It is clearly stipulated that it is strictly forbidden to hang low and use high. If the tester climbs the bushing wiring, if he is a little careless, he will fall due to the breakage of the bushing porcelain bottle or step on the air, causing personal and equipment damage.
