Description

A kind of multi-functional sealing assembly with upper ground connection
Technical field
The utility model belongs to high pressure sealing insulation assembly field, particularly a kind of multi-functional sealing assembly with upper ground connection.
Background technology
At present, the ring main unit used on urban distribution network is SF basically 6the gas-insulated ring network cabinet, there are the shortcomings such as Leakage Gas, blast, contaminated environment, poor reliability, high, difficult in maintenance, the intelligent degree of failure rate 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 a kind of novel ring main unit, carry out certainly the problems referred to above.
The utility model content
The purpose of this utility model is to provide a kind of multi-functional sealing assembly with upper ground connection, has isolating switch, vacuum extinction switch and vacuum earthed switch, can meet 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 sealing assembly with upper ground connection, it is characterized in that: comprise the epoxy resins insulation part, be provided with vacuum extinction switch, isolating switch and vacuum earthed switch in the epoxy resins insulation part.
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 for controlling the first insulated tension pole of break-make between arc-suppressing switch moving contact and arc-suppressing switch fixed contact, and the outer end of arc-suppressing switch fixed contact is connected with for connecting the electric conductor of external high pressure cable.
The vacuum earthed switch comprises grounding contact, moving contact of grounding switch and the static contact of grounding switch for ground connection, grounding contact is electrically connected to static contact of grounding switch, and the outer end of moving contact of grounding switch is connected with for controlling the second insulated tension pole of break-make between moving contact of grounding switch and static contact of grounding switch.
Isolating switch comprises static contact isolation switch, isolating switch moving contact, isolation switch and the isolation pull bar be 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, the middle part of isolation switch is connected with for controlling the isolation pull bar of break-make between isolation switch and static contact isolation switch.
Be electrically connected between arc-suppressing switch moving contact and isolating switch moving contact, be electrically connected between arc-suppressing switch moving contact and moving contact of grounding switch.
During work, static contact isolation switch of the present utility model is connected with the high voltage switchgear main bus bar, the lower electric conductor of vacuum extinction switch is connected to the external high pressure cable, and the ground switch earthing contact connects the earth.
When earthed switch, in open position, isolating switch is in closing position, and the vacuum extinction switch is when closing position, and the main bus bar of high voltage switchgear and lower electric conductor conducting, can deliver to the external high pressure cable by the high-tension electricity of the main bus bar of high voltage switchgear.
When earthed switch, in closing position, the vacuum extinction switch is in open position, and isolating switch is when open position, and external cable and the earth conducting, can, by the external high pressure cable grounding, be grounded function.
When earthed switch, in open position, isolating switch, when open position, no matter the vacuum extinction switch, in where, disconnects between the main bus bar of external high pressure cable and high voltage switchgear, is realized isolation features.
The utility model can be by vacuum extinction switch, isolating switch, vacuum earthed switch the different conditions combination of combined floodgate/separating brake (conducting/disconnection), can complete isolation, ground connection and conducting function, meet the difference in functionality demand of switchgear.
The accompanying drawing explanation
The structure principle chart that Fig. 1 is the first embodiment.
