Description
The utility model relates to a kind of bushing.
Existing bushing mainly contains following several structural type: 1, porcelain bushing shell structure (as shown in Figure 1 and Figure 2), guide rod (pipe) 1 and inside and outside insulator 2,3 are rigid body, guide rod (pipe) 1 outside is a capacitor core 4, capacitor core 4 all presses screen 7 and paper oil insulation layer 8 to form by the aluminium foil that alternately is wrapped on the guide rod (pipe) 1, between the inside and outside insulator 2,3 of equipment or body of wall is mounting flange dish 5, filling fluid insulation oil 6 between capacitor core 4 and porcelain tube 2.Its shortcoming is that weight is big, and insulator is easy to damage, leakage of oil easily, and inflammable and explosive, antifouling property is relatively poor.2, for solving " soft " formula plastic sleeve structure (as shown in Figure 3) that above-mentioned shortcoming designs, it is that the cable core of twisted polyethylene cable is led core 9 as metal, the isolation layer of cable is made solid insulating layer 10, all press screen 11 and teflon insulation layer 12 alternately to twine with aluminium foil vertically in isolation layer 10 outsides and make equalizing press layer, outermost surface adopts the multiphase polymer Radiation Crosslinking Heat to make oversheath 13.It is in light weight, and operation maintenance is easy, can solve problems such as the leakage of oil of porcelain bushing shell, inflammable and explosive and antifouling property, but can only pack cable core by hand, unsuitable mass production; Because integral body is soft structure, during installation, two ends need support insulator to support, and soft oversheath 8, subject to damage simultaneously.3, for addressing the above problem, " firmly " formula plastic sleeve structure (as shown in Figure 4) has appearred again, it still adopts rigidity guide rod (pipe) 14 and capacitor core 15 structural types in the porcelain bushing shell, but change the paper oil insulation layer in the capacitor core 14 into teflon insulation layer 16, and removed fluid insulation oil, directly fix the oversheath made from the multiphase polymer Radiation Crosslinking Heat 17 in capacitor core 14 outsides in " soft " formula plastic sleeve structure, flange plate 18 directly is stuck on the oversheath 17.This kind structure has strengthened leading the skeleton function of core by rigidity guide rod (pipe), the support insulator that has saved two ends supports, make install and use very convenient, but still there is following problem in it, 1. guide rod (pipe) should bear high voltage as core body and bear mechanical force (this mechanical force is delivered to flange plate 18 by oversheath 17) again simultaneously, and insulation is easy to damage.2. the easily vulnerable problem of soft oversheath does not solve well.
It is little that the purpose of this utility model provides a kind of volume, in light weight, and operation maintenance is easy, and fire prevention, dry type explosion-proof, that antifouling property is good do not have innage gland pipe.
To achieve these goals, the utility model is taked following design: a kind of dry type does not have innage gland pipe, it comprises guide rod (pipe), by all pressing screen and isolation layer alternately to twine the capacitor core of forming, oversheath, be arranged on the packing between described capacitor core and the oversheath, be arranged on the flange plate at described oversheath middle part, be arranged on the measurement terminal on the described flange plate, and be arranged on the high-field electrode at described capacitor core and oversheath two ends, it is characterized in that: described oversheath is made up of with the silicone rubber external insulation layer that is fixed in described high-intensity resin tube outside the high-intensity resin pipe of rigidity, and the packing between described capacitor core and the described oversheath is a macromolecular material.
Described guide rod (pipe) can lead to outside the described high-field electrode at two ends, and described high-field electrode is fixed on the described guide rod (pipe).
Described guide rod (pipe) also can lead to indoor end outside the described high-field electrode of this end, and the two is fixed, and the outdoor end of guide rod (pipe) is contracted in the described high-field electrode of this end, on this high-field electrode, fix a pigtail splice, and be flexible coupling by one and be communicated with described guide rod (pipe).
The material of described high-intensity resin pipe can adopt epoxy resin.
Described macromolecular material as packing can be the silicone rubber that pours into and be solidificated between described oversheath and the capacitor core.
The material of described measurement terminal is plastics.
The utility model is owing to take above design, it has the following advantages: 1, the utility model since between oversheath and capacitor core perfusion and cure silicone rubber or fill other insulating polymeric material as packing, therefore, compare with porcelain bushing shell, thoroughly solved leakage of oil and, made operation maintenance very easy by the problem such as inflammable and explosive that leakage of oil causes; Compare with " firmly " formula plastic bushing with " soft " formula plastic bushing, insulation and anti ageing property are greatly improved, and in mechanical force in the process that flange plate transmits, bear mechanical force jointly by the guide rod (pipe) of rigidity and the oversheath of rigidity, perhaps only bear mechanical force, greatly reduced the stressed of capacitor core by oversheath.2, the utility model is owing to removed insulator, the double layer construction oversheath that has adopted high-intensity resins such as epoxy resin and silicone rubber insulation layer to form by rigidity, compare the rigid construction that has both kept oversheath with porcelain bushing shell, make volume-diminished again, weight lightens, and has solved the problem that insulator is easy to damage simultaneously; Compare with " soft " formula plastic bushing, the whole two ends of rigidity are supported without support insulator; Compare with " firmly " formula plastic bushing, the problem that insulator is born than great machinery power has obtained effective solution.3, because external insulation layer of the present utility model adopts the mode of the high-intensity resin tube outside that is fixed in rigidity, and because it adopts silicone rubber material, comparing antifouling property with porcelain bushing shell is greatly improved, compare with " firmly " formula plastic bushing with " soft " formula plastic bushing, solved the easily vulnerable problem of soft oversheath well.It is little, in light weight that the utility model had both had in the conventional art volume, dry type does not have oil, and operation maintenance is easy, and is fire-proof and explosion-proof, features such as antifouling anti ageing property is good, it is good to have integral rigidity again, and capacitor core is not subjected to mechanical force, and two ends need not be supported, advantages such as oversheath is not fragile, it can be used as high-voltage wall bushing, also can be used as in the high pressure equipment such as bushing shell for transformer, circuit breaker sleeve pipe, and can be widely used in the various occasions that need bushing.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
