According to the multi-functional solid seal assembly, different state combinations of switching on or switching off of the vacuum arc extinguishing switch, the isolating switch and the vacuum grounding switch can be utilized to achieve isolation, grounding and conduction functions and meet different functional requirements of switchgear.
Description
Technical field
The invention belongs to height and press solidly envelope insulation assembly field, particularly a kind of multi-functional solid sealing assembly.
Background technology
At present, employed ring main unit is SF basically on the urban distribution network
6The gas-insulated ring main unit, there are shortcomings such as gas leakage, blast, contaminated environment, poor reliability, failure rate height, difficult in maintenance, intelligent degree be low in this ring main unit, having limited it further develops, for development and the environmental requirement that adapts to intelligent grid, people urgently wish to have a kind of novel ring main unit, come certainly the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of multifunction combined solid sealing assembly, have isolating switch, vacuum extinction switch and vacuum earthed switch, can satisfy isolation, vacuum circuit-breaker and grounding function requirement simultaneously.
The technical scheme that realizes the technical scheme of above-mentioned purpose is: a kind of multi-functional solid sealing assembly is characterized in that: comprise epoxy resins insulation spare, be provided with vacuum extinction switch, isolating switch and vacuum earthed switch in described epoxy resins insulation spare; The vacuum extinction switch comprises vacuum interrupter, at indoor arc-suppressing switch moving contact and the arc-suppressing switch fixed contact of being provided with of vacuum extinction, the outer end of arc-suppressing switch moving contact is connected with first insulated tension pole for break-make between control arc-suppressing switch moving contact and the arc-suppressing switch fixed contact, and the outer end of arc-suppressing switch fixed contact is connected with for the electric conductor that connects the external high pressure cable; The vacuum earthed switch comprises grounding contact, earthed switch moving contact and earthed switch fixed contact, and the outer end of earthed switch moving contact is connected with second insulated tension pole for break-make between control earthed switch moving contact and the earthed switch fixed contact; Described isolating switch comprises static contact isolation switch, isolating switch moving contact, isolation switch and the isolation pull bar that is connected with the high voltage switchgear main bus bar, one end of isolation switch is connected with the isolating switch moving contact, but the other end of isolation switch is connected with the static contact isolation switch break-make, and the middle part of isolation switch is connected with the isolation pull bar for break-make between control isolation switch and the static contact isolation switch; Be electrically connected between described arc-suppressing switch moving contact and the isolating switch moving contact, be electrically connected between the arc-suppressing switch moving contact of the arc-suppressing switch fixed contact of vacuum extinction switch and the earthed switch fixed contact of earthed switch or vacuum extinction switch and the earthed switch moving contact of earthed switch, described grounding contact is connected not on the earthed switch moving contact or earthed switch moving contact that are electrically connected with the vacuum extinction switch.
During work, static contact isolation switch of the present invention is connected with the high voltage switchgear main bus bar, the following electric conductor of vacuum extinction switch is connected to the external high pressure cable, and the earthed switch grounding contact connects the earth.
When earthed switch is in the separating brake position, isolating switch is in closing position, and when the vacuum extinction switch was in closing position, the main bus bar of high voltage switchgear and following electric conductor conducting can be delivered to the external high pressure cable with the high-tension electricity of the main bus bar of high voltage switchgear.
When earthed switch is in closing position, the vacuum extinction switch is in the separating brake position, and when isolating switch was in the separating brake position, external cable and the earth conducting can be grounded function with the external high pressure cable grounding.
When earthed switch is in the separating brake position, when isolating switch is in the separating brake position, no matter where the vacuum extinction switch is in, disconnect between the main bus bar of external high pressure cable and high voltage switchgear, realize isolation features.
The present invention can be by vacuum extinction switch, isolating switch, vacuum earthed switch the different conditions combination of combined floodgate/separating brake (conducting/disconnection), can finish isolation, ground connection and conducting function, satisfy the difference in functionality demand of switchgear.
