This contact box the whole L that is appear, including whole columniform pipe wall and the lumen of being, contact box one end has round opening, and corresponding setting up of outer wall is the contact box stiff end, is provided with the fixed orifices on four angles of its stiff end respectively, contact box one end is the confined cap body, the corresponding copper bar rectangle outlet pipe of connecting. This contact box adopts glass fiber reinforcement and the fire -retardant direct injection moulding of the modified material of thermoplastic resin.
Description
Technical field
The utility model relates to and is applied to voltage in indoor (10-20KV) all kinds of contact box, in particular to fire-retardant, the callable material modified novel contact box prepared by injection mo(u)lding of employing, have the advantages that the electrical properties such as creepage trace are excellent, mechanical strength is high.
Background technology
The continuous propelling that country's intelligent grid is built, the strategy that distribution is first developed makes the demand of city's field alignment pressure primary equipment increase.At present, insulating part is in such devices adopt material based on epoxy resin mostly.There is the difficult problem that cannot be recycled in the epoxy resin of solidification, easily causes environmental pollution, be unfavorable for environmental protection, do not meet the requirement of sustainable development.Meanwhile, in controller switching equipment, the requirement of insulating material fire resistance improves constantly, and will seriously reduce technical advantage and the life cycle of epoxies product.Country also can get more and more to the incentives that the development and application of environment-friendly type switchgear is promoted.
Strengthening the application study to organic combined insulated material and exploitation in the world, to reach the object of energy-conserving and environment-protective.ADD company of the U.S., French ERICO company, ABB AB are many at development environment-friendly thermoplastic composite insulating material, and existing procucts come into operation in electrical network, as the pole etc. of solid insulation ring main unit, nylon material.
The material modified insulating part main material as compound inslation switchgear of PA6, its mechanical property, resistance to wear, corrosion resistance are strong, molding processibility good.Through filling and toughening modifying, its performance strengthens greatly, and electric property and mechanical performance meet the insulating requirements of compound inslation switchgear completely.Simultaneously PA6 insulating material also has following characteristics: raw material weight is light, with short production cycle, the lifetime long (30 years can be reached), little, the recyclable recycling of internal stress after processing; Product producing process adopts Shooting Technique, low production cost.Material itself is nontoxic in addition, does not have penetrating odor, do not affect environment in manufacture link.The recyclable regenerative ratio of product, meets the requirement of national sustainable development, and moderate.
Contact box of the present utility model adopts glass fiber reinforcement and the fire-retardant direct injection mo(u)lding of thermoplastic resin modified material, can be widely used in solid insulation ring main unit, high-voltage switch gear, there are the insulation property of loop-like epoxy resins, and there is the processing feature such as simple, recyclable, fire-retardant.
Utility model content
The utility model provides one to have very good mechanical properties, processing characteristics, insulation property, returnable fire-retardant contact box.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A contact box for the mesohigh electricity cabinet of thermoplastic flame-proof, this contact box entirety is L-shaped, comprises overall cylindrical tube wall and tube chamber; Contact box one end has circular open, corresponding outer wall be set to contact box stiff end, four angles of its stiff end are respectively arranged with fixing hole; Contact box one end is closed cap body, is correspondingly connected to copper bar rectangular outlet pipe.
Further, the tube wall inwall of contact box is provided with inner skirt, is provided with outer skirt in the middle part of tube wall outer wall.
Further, described in contact box, there is copper bar retaining thread hole at the center, top of cap body.
Further, this contact box adopts glass fiber reinforcement and the fire-retardant direct injection mo(u)lding of thermoplastic resin modified material.
Further, glass fiber reinforcement fire-retardant thermoplastic resin modified material contact box is thin wall type, instead of heavy wall type epoxy resin contact box, and contact box has, and intensity is high, good toughness, and collision does not damage.
Further, all fixing holes are brass inserts.
Further, this contact box is applicable to 630 amperes-4000 amperes, electric current, voltage 40.5KV and following.
The beneficial effect of employing the technical solution of the utility model is: use raw material few, the internal stress that material proportion is little, with short production cycle, the lifetime is grown after (can reach 30 years), processing is little, material itself is nontoxic in addition, does not have penetrating odor, do not affect environment in manufacture link.The recyclable regenerative ratio of product, meets the requirement of national sustainable development.
