Compared to the prior art, the thermoplastic material solid-sealed polar pole vacuum circuit breaker reduces the product weight, improves the insulating and mechanical performance, and reduces the product size with excellent usability of the solid sealing material and high bonding intensity. In addition, the thermoplastic material solid-sealed polar pole vacuum circuit breaker decreases or eliminates the generation of the air holes and small cracks and improves the product quality.
Description
Technical field
The utility model belongs to breaker technical field, is specifically related to the technology that a kind of thermoplastic material is applied to the pole vacuum circuit-breaker.
Background technology
Pole is that the conductive pieces that vacuum interrupter is relevant with circuit breaker is embedded into simultaneously in the solid insulating material that this class of epoxy resin solidifies easily and forms pole, makes whole circuit breaker
Three-phasePole
GroupBecome as a whole parts.The pole modularized design, simple in structure, detachable part is few, and reliability is high; Have high insulating capacity, it becomes surface insulation into the volume insulation, compares air insulation, has reduced the impact of environment, has greatly improved dielectric strength.Therefore adopt epoxy resin pole vacuum circuit-breaker to be widely applied.
Pole vacuum circuit-breaker manufacturer is more; model is different; but most products all exists poured with epoxy resin technique undesirable qualitatively; pore or fine cracks are arranged; the control defencive function is imperfect; particularly to the problem of the aspects such as transition material, cast temperature, injection pressure control still in constantly improving; exist in the casting cycle shrink inconsistent, adhesion strength is not high, epoxy encapsulation has the problems such as pore and fine cracks, and insulation of electrical installation performance, the safe operation that becomes switchgear house have been caused certain hidden danger.Epoxide resin material is not easy to reclaim in addition, has environmental issue.
The utility model content
For solving the problems of the technologies described above, the utility model aims to provide a kind of thermoplastic material pole vacuum circuit-breaker, the fixed sealing material good manufacturability, and adhesion strength is high, the generation that reduces or stop pore and fine cracks, and have lightweight, volume is little, insulation property and mechanical performance advantages of higher.
For achieving the above object, adopted following technical scheme:
A kind of thermoplastic material pole vacuum circuit-breaker comprises vacuum interrupter and upper and lower leading-out terminal current-carrying element, and vacuum interrupter and upper and lower leading-out terminal current-carrying element seal admittedly with the mould material main body, it is characterized in that solid envelope mould material main body is thermoplastics.Plastic processing is solidified after the cooling, and heating still can reach mobile again, and can again carry out machine-shaping to it, that is to say to have good re-workability and being recycled property.
The comparison of thermoplastic pole and epoxy resin pole: compare with the epoxy resin pole by thermoplastic pole relatively, thermoplastic material can reduce about 35 % of whole pole weight, only insulating material just makes quality reduce more than 1/3rd, by reducing the density 12% of thermoplastic material, dielectric strength improves about 50%, it is about 100% that mechanical rigid improves, and mechanical strength improves 300-400%, thereby reached the purpose of weight saving; In addition, these improve the volume that has also further dwindled product.
The pole chamber is inboard directly to be contacted with the ceramic package surface of vacuum interrupter, so its machinery, heating and insulation property are most important to PT type pole.An interface between thermoplastics and pottery and the metal, the large Wei of its operating temperature range – 30oC~+ 115 oC, because the adhesiveness between thermoplastic material and iron and steel and other metal material is very low, therefore be easy to from mould, take out electrode, and then general assembly pole and test, can guarantee that mechanical stability and fracture elongation bring up to maximum.
During implementation, above-mentioned thermoplastics is Polyamide Engineering Plastic.Polyamide has good combination property, comprise mechanical property, thermal endurance, mar proof, chemical proofing and self lubricity, and coefficient of friction is low, preferably anti-flammability is arranged, be easy to processing, be suitable for short glass fiber and other filler filling enhancing modified, improve performance and enlarge range of application.
During implementation, above-mentioned thermoplastics is the thermoplastics of compound short glass fiber.
Can adopt aborning very high injection pressure, therefore can use short glass fiber at thermoplastics.Adopt the low-pressure injection molding shaping of epoxy resin composite material can not accomplish this point.For various compositions are fully mixed, keep than low viscosity, epoxy resin composite material contains silica flour usually.In thermoplastics, increased the part short glass fiber, consider simultaneously same material matrix structure, therefore allow higher mechanical rigid and larger mechanical strength in machine direction, can convert the thermoplastic pole to from the epoxy resin pole smoothly on technique, therefore the thermoplastic pole still keeps the overall dimension of epoxy resin pole.In addition, all functional sizes equate that all therefore these parts have interchangeability, and pull bar and flexible link also keep same size.
Thermoplastic material pole vacuum circuit-breaker not only possesses the advantage of epoxide resin material pole vacuum circuit-breaker, and can also satisfy more high-quality requirement, has optimized dielectric insulation, protected vacuum interrupter and has realized non-maintaining operation.Consider that from the angle of environment the thermoplastic material pole has had great improvement than epoxy resin pole, both has been beneficial to environmental protection production, the casting flawless is suitable for again recycling.The utility model has not only been considered the production of pole itself, has also considered the production of basic material.Show that by calculating the production of thermoplastic pole has descended about 50% than its in earlier stage CO2 emission of product.
The utility model is compared with the epoxy resin pole, and thermoplastic material can reduce about 35 % of whole pole weight, by reducing the density 12% of thermoplastic material, dielectric strength improves 50% approximately, mechanical rigid improves 100% approximately, and mechanical strength improves 300-400%, thereby has reached the purpose that quality alleviates; In addition, these improve the volume that has also further dwindled product, make the total qualities such as pole circuit breaker quality, insulation property that larger lifting arranged.
Beneficial effect: the utility model has compared with prior art alleviated product weight, has improved insulation property and mechanical performance, dwindled the volume of product, and the fixed sealing material good manufacturability, adhesion strength is high, the generation that reduces or stop pore and fine cracks has improved product quality.
