High-voltage line disconnecting switch

Abstract

The invention relates to the electricity field, and specifically relates to a high-voltage line disconnecting switch. The high-voltage line disconnecting switch comprises a base, two pillar insulators, a left binding post, a right binding post, an upper contact, contact seats and telescopic connection devices; the two pillar insulators are respectively disposed on the left and right sides of the top of the base, the left binding post is disposed on the left-side pillar insulator, the right binding post is disposed on the right-side pillar insulator, the top ends of the pillar insulators are provided with the contact seats, the upper contact is disposed above the contact seats, the upper contact and the contact seats are connected through the two telescopic connection devices, each telescopic connection device comprises an outer telescoping sleeve, inner telescoping rods, spring hooks, a spring and rotation fixing members, and the number of the inner telescoping rods is four. Opening operation and closing operation are easy, the telescopic connection devices of the high-voltage line disconnecting switch are convenient to rotate and telescope, and convenience is provided for assistance of opening and closing between the contact seats and the upper contact; and the springs are prevented from being corroded and destroyed, device endurance is increased, and the high-voltage line disconnecting switch has high practicality.

Description

technical field [0001] The invention relates to the field of electricity, and in particular relates to a high-voltage line isolating switch. Background technique [0002] At present, the high-voltage isolating switch commonly used in power system distribution lines is very easy to rust due to being corroded by rain and snow outdoors for a long time, which makes it very inconvenient to operate the switch part when opening and closing. For example, the commonly used HGW9-12 series of outdoor high-voltage disconnectors are equipped with fixed hooks and self-locking devices. They are operated with insulating hook rods and are corroded by natural factors such as rain and snow for a long time. The rotating shaft of the moving contact is easy to rust, which makes the moving contact easy to cause the situation that the closing and closing are not in place and the opening cannot be separated during the closing and opening operations, which has a negative impact on the operation work ...
