The solid insulating ring main unit disclosed by the invention is safer and more reliable in operational process, relatively low in manufacturing and maintenance cost, harmless for the environment and human bodies, recyclable and reusable, easy to carry and low in cost, and the integral weight is reduced.
Description
Technical field
The present invention relates to a kind of switch cubicle, relate to a kind of solid insulation switch cabinet specifically.
Background technology
Pole housing in existing insulation ring main unit adopts epoxide resin material usually, and epoxide resin material is fragility, and its insulation property are suffered to damage rear irrecoverable, and not only the use of impact insulation ring main unit, also may damage human body; In addition, what adopt in process of production is that product after epoxy resin cure is as raw material, production process can add diluent, curing agent and promoter, therefore most epoxy coating is solvent based coating, containing a large amount of volatilizable organic compounds (VOC), epoxide resin material is made all to cause severe contamination and harm to environment and human body in production and use procedure, and epoxy resin cost is high, the pole housing be made up of epoxy resin reclaims difficulty when useful life terminates.
Summary of the invention
The object of this invention is to provide a kind of solid insulation ring main unit, its running safety and reliability, manufacture and maintenance cost is lower, to environment and body harmless, recyclable recycling, overall weight alleviates easily carrying and cost is low.
To achieve these goals, technical solution of the present invention is: a kind of solid insulation ring main unit, comprise housing and be arranged at the pole body in housing, pole body comprises pole upper shell, pole lower house, and described pole upper shell, pole lower house fibreglass strengthen nylon resin and make.
Solid insulation ring main unit of the present invention, wherein, described pole body also comprises inlet wire conductor, vacuum interrupter, outlet conductor, described pole upper shell, pole lower house fibreglass strengthen nylon resin cast and form, and described inlet wire conductor, vacuum interrupter, outlet conductor setting-in are cast in together in described pole upper shell casting process.
Solid insulation ring main unit of the present invention, wherein, described pole upper shell, pole lower house outermost are all coated with screen.
Solid insulation ring main unit of the present invention, wherein, described screen is semiconductor layer.
Solid insulation ring main unit of the present invention, wherein, described pole body also comprise be flexible coupling, circuit breaker tie rod, fixed contact, described in one end of being flexible coupling be connected fastening by bolt with described fixed contact, described in the other end that is flexible coupling be connected with described vacuum interrupter by described circuit breaker tie rod.
After adopting such scheme, compared with prior art due to the pole upper shell of solid insulation ring main unit of the present invention, pole lower house fibreglass strengthens nylon resin and makes, glass fibre reinforced nylon resin mechanical property, dimensional stability, thermal endurance, ageing-resistant performance is all stronger, endurance life is 2.5 times of traditional material, pole body is made to have had conduction concurrently, heat radiation, insulation, the multiple functions such as support and connection, in addition, because glass fibre reinforced nylon resin electric insulation is good, the volume resistance of nylon is very high, breakdown voltage resistant height, in dry environments, power frequency insulating material can be made, even if in high temperature environments still there is good electrical insulating property, make whole solid insulation ring main unit running safety and reliability, also have, glass fibre reinforced nylon resin mechanical strength is high, good toughness, there is the resistance to impact of higher tension, compression strength and excellence, there is again lower melt viscosity, can flow fast, be easy to mold filling, mold filling after coagulation point is high, energy fast shaping, therefore molding cycle is short, production efficiency is improved, moreover glass fibre reinforced nylon resin has self-extinguishment, nontoxic, odorless, good weatherability, be inertia to bioerosion, have good antibacterial, Antimould power, and with after can all reclaim and recycle, to environment without any harm, meet the requirement that green network is built, glass fibre reinforced nylon resin density is little, lightweight, cost is low, makes whole solid insulation ring main unit weight saving, cost reduction.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of solid insulation ring main unit of the present invention;
Fig. 2 is the outside drawing of pole body in solid insulation ring main unit of the present invention;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Embodiment
As shown in Figure 1, 2, solid insulation ring main unit of the present invention comprises housing 11 and is arranged at bus-bar room 21 in housing 11, pole body 22, cable vault 24, mechanism chamber 25, control room 26, housing 11 is provided with cabinet door, pole body 22 comprises pole upper shell 221, pole lower house 222, and pole upper shell 221, pole lower house 222 fibreglass strengthen nylon resin and make.
As shown in Figure 3, pole body 22 also comprises inlet wire conductor 223, vacuum interrupter 224, outlet conductor (not shown), be flexible coupling 225, circuit breaker tie rod 226, isolation main shaft 227, outlet bus 228 and outlet casing tube 229, pole upper shell 221, pole lower house 222 fibreglass strengthens nylon resin cast and forms, by inlet wire conductor 223 in pole upper shell 221 casting process, vacuum interrupter 224, outlet conductor setting-in is cast in together, and pole upper shell 221, pole lower house 222 outermost is coated with the screen that semiconductor layer is made, be flexible coupling 225, circuit breaker tie rod 226 is arranged in the cavity of pole upper shell 221, and be flexible coupling 225 one end be connected fastening by bolt with fixed contact 220, be flexible coupling 225 the other end be connected with vacuum interrupter 224 by circuit breaker tie rod 226.Form because pole upper shell 221, pole lower house 222 to be poured into a mould by Standard Module by glass fibre reinforced nylon resin, be therefore easy to the satisfied morpheme requirement such as vertical, parallel, whole pole body installed more simple and convenient.Together with in casting process, pole upper shell 221 is cast in inlet wire conductor, vacuum interrupter, outlet conductor setting-in, pole body is made to become as a whole, simple, the detachable part of structure is few, reliability is high, surface insulation is become volume insulation simultaneously, substantially increases dielectric strength.
During solid insulation ring main unit work of the present invention, electric current passes through inlet wire conductor flow through vacuum interrupter by bus-bar room, by to be flexible coupling and fixed contact, isolation blade, outlet bus and outlet casing tube enter cable vault and flow in outlet cable, wherein the circuit breaker of vacuum interrupter, circuit breaker tie rod and mechanism's composition rises and cut-offs the arc extinguishing function of current.Pole upper and lower casing plays a part support, insulation, shielding external interference.The isolating switch of isolation main shaft, interrupter composition plays a part safe fracture and provides visual fracture.
