Abstract
The invention relates to a sliding isolation device for on-off switches of high-voltage switch apparatuses, wherein the high-voltage switch apparatuses refer to vacuum circuit breakers and vacuum load switches. The sliding isolation device is matched with the vacuum circuit breakers or the vacuum load switches for use to increase a safe electric distance between a main bus bar and charged conductors and uncharged conductors at a line outgoing side; and as the distance between a moving contact and a fixed contact in a vacuum bulb is smaller, short-circuit accidents may happen if the air leakage of the vacuum bubble results in the reduction of electric insulation, the accidents can be avoided if the sliding isolation device is arranged at the front side of the vacuum bubble. The sliding isolation device has the advantages of safety, reliability, small volume and good effect either in an electric conducive state or isolation state.
Description
Affiliated technical field
Type of the present invention relates to the used slip spacer assembly of a kind of high voltage switchgear on-off circuit, and high voltage switchgear refers to vacuum circuit-breaker, vacuum load switch.
Background technology
High voltage switchgear is generally used for switching on and off the power transmission and distribution loop under zero load, normal duty or the short-circuit condition, and the power on/off of high voltage switchgear is mainly leaned on the vacuum bubbles moving contact and realized effective connection of fixed contact.
Under modern technologies, because of the spacing between moving contact in the vacuum bubbles and the fixed contact less, as descending because of vacuum bubbles gas leakage causes electric insulation, may cause short circuit accident to take place, so vacuum bubbles generally cooperates isolating switch to use in the high voltage switchgear, purpose is to increase isolation fracture, generally selects GN30, GN22 type isolating switch for use, but the isolating switch volume that cooperates can be very big, causes the switch cubicle equipment volume can be very big.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, volume is less, contact area is big, electric conductivity is reliable, install simple, be applicable to vacuum circuit-breaker or vacuum load switch and be used, increase is the charged and outlet side electrical safety distance between not charged because of main bus bar, the possibility of avoiding accident to take place.Reduce the worry that the user uses.
Technical scheme of the present invention is achieved in that and makes by sliding contact up or down slip in the slip separate cavities and to realize synchronous conducting and disconnection with the main line switch.
The invention has the beneficial effects as follows:
A kind of slip spacer assembly of the present invention provide a kind of simple in structure, volume is less, contact area is big, electric conductivity is reliable, and simple spacer assembly is installed.
