DISCONNECTOR FOR ARRESTER GROUNDING FOR EXTRA-HIGH VOLTAGE SUBSTATION

摘要

The present invention relates to a disconnector for arrester grounding for an extra-high voltage substation. The disconnector for arrester grounding for an extra-high voltage substation comprises: a grounding terminal formed on an upper side of an arrester (including an insulator-type arrester) installed on a support; a ground line connecting hole formed at a lower portion of the grounding terminal to be able to move vertically; a frame having a vertical through hole and an axial hole, in which the ground line connecting hole is attached to a lateral side of the support; a lifting bar having a guide protrusion inserted into the through hole to be guided and having a gear unit formed on one side thereof; a connection terminal unit coupled to an upper portion of the lifting bar and having a grounding insertion groove; a grounding line connected to the connection terminal unit to ground to the earth through the lifting bar; and a lifting bar operating unit which is rotatably coupled to the frame to vertically move the lifting bar. According to the effect of the present invention, an operator can connect to or disconnect from the ground wire to the grounding terminal of the arrester only by operating the lifting bar upward/downward while the operator stands up on the ground without approaching the arrester directly, thereby enabling to securely, quickly, and conveniently connect the ground wire.;COPYRIGHT KIPO 2017
