Two, dielectric chamber is exposed on cabinet, there is condensation problem, thus easily causes insulation fault;
Three, current, on market, dielectric chamber all adopts epoxy resin to make, and cannot degrade, not environmentally;
Four, the bus between cabinet with cabinet is connected the mode adopting and eject, then connects with isolated bus, and cost is higher.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of solid insulation ring main unit of safe and reliable, energy-conserving and environment-protective.
The utility model solves the technical scheme that its technical problem adopts: a kind of solid insulation ring main unit, has upper wardrobe body, lower cabinet body and for connecting both cable ends; Described upper wardrobe body is containment housing, and upper wardrobe body inside is provided with switch element, and right side central is provided with tri-station isolating switch mechanism, and lower right side is provided with on-load switch mechanism; Described switch element comprises end cap, ground connection tool rest and dielectric chamber, vacuum bubbles, copper conductor, pitman, isolation knife, isolation tool rest and insulated tension pole is provided with in described dielectric chamber, described copper conductor is connected on end cap, described tri-station isolating switch mechanism is connected with connecting lever, the other end of described connecting lever is connected with connecting rod, and the other end of described connecting rod is hinged on the middle part of isolation knife; The left end of described isolation knife is hinged on isolation tool rest, and right-hand member is movably connected on the other end of ground connection tool rest or copper conductor; The left end of described insulated tension pole is connected with the right-hand member of vacuum bubbles, and right-hand member is connected with on-load switch mechanism; The left end of described vacuum bubbles is connected with the top of pitman; The bottom of described pitman is connected with the top of cable end.
Dielectric chamber described in technique scheme is made up of callable thermoplastic insulation material.
Bus described in technique scheme between upper wardrobe body and lower cabinet body connects the mode adopting side to connect.
The beneficial effects of the utility model are: this solid insulation ring main unit has following good effect:
One, by adopting the mode of upper isolation, the ground connection being carried loop by vacuum bubbles closes, and safe and reliable, ground connection making capability improves greatly;
Two, main conductive circuit and insulating part are sealed in containment housing, be dry pure air, avoid the generation of condensation problem, switchgear fail safe is improved greatly in containment housing; In addition, by totally-enclosed design, make the small volume of ring main unit, completely cut off steam, greasy dirt and dust, also further increase its insulation property; Meanwhile, because main conductive circuit is sealed in containment housing, main conductive circuit can realize non-maintaining, greatly reduces equipment operation maintenance cost;
Three, dielectric chamber adopts recyclable thermoplastic insulation material to make, and wall thickness is thinner, and can degrade, environment protecting is remarkable;
