Embodiment 1

[0023] The occluder of Embodiment 1 accommodates a ceramic column of the ceramic column knife switch in the accommodation space through the housing 10, so that the housing 10 is wrapped around the outer side of the ceramic column, and the housing 10 can be fixed by setting the locking rod 20 On the porcelain pillar, the housing 10 is prevented from detaching from the porcelain pillar. Through the package of the shell 10, the ceramic column is isolated from the outside world, effectively preventing the operator from accidentally touching the ceramic column during live operation, so that the work of repairing the ceramic column knife switch can be carried out live, avoiding Losses caused by power outage repairs.

[0024] The housing 10 includes a first side wall and a second side wall oppositely disposed, and a connecting wall connected between the first side wall and the second side wall. The section of the accommodation space surrounded by the first side wall, the second side...

Abstract

The invention provides a shielding piece of a knob insulator disconnecting link. The shielding piece comprises a shell and a locking rod, wherein a containing space used for containing a knob insulator of the knob insulator disconnecting link is formed in the shell, and the containing space is provided with an opening; the locking rod is rotatably arranged on the shell, and the locking rod has a locking position and an unlocking position which are used for enabling the knob insulator to be located in the containing space. By the adoption of the shielding piece of the knob insulator disconnecting link, the danger that operators accidentally touch the knob insulator in the process of hot-line work is effectively prevented through the shell arranged on the knob insulator in a covering mode, therefore, the work of repairing the knob insulator disconnecting link can be carried out in a hot-line work mode, and the loss caused by power outage repair is avoided.

Description

technical field [0001] The invention relates to the field of electric safety, in particular to a shield for a porcelain pillar knife switch. Background technique [0002] In the prior art, when the load side line card of the disconnector ceramic column knife switch on the 10KV power distribution line processing column breaks or the lead wire falls off, the safety distance is not enough due to the small distance between the two ceramic columns , It will cause potential safety hazards to operators during live operation. Therefore, when repairing the load side line card or lead wire falling off, it is necessary to perform power outage treatment on the distribution line. Contents of the invention [0003] The present invention aims to provide a shielding member for a porcelain pillar knife switch, so as to solve the problem of potential safety hazards in the prior art when the porcelain pillar knife switch is operated live. [0004] In order to achieve the above object, the p...
