Abstract
The utility model discloses a novel transformer wire outgoing casing pipe structure, comprising a porcelain body and a porcelain cover fixedly connected with the porcelain body, and further comprises electroconductive rods arranged on the porcelain cover in a through manner, wherein one end of each electroconductive rod, extending out of the porcelain cover, is provided with a terminal block, a combination part between the porcelain body and the porcelain cover is further provided with a fixing flange in a sleeving manner, and gaps between the fixing flange and the porcelain body and between the fixing flange and the porcelain cover are filled with colloids; a rainproof cover covers the end of each electroconductive rod, extending out of the porcelain cover, and is connected with the fixing flange; and an outer seal ring is arranged on a contact part between each electroconductive rod and the upper surface of the porcelain cover, an annular step face is arranged on a contact part between each electroconductive rod and the lower surface of the porcelain cover, and an inner seal ring is arranged between the annular step face and the lower surface of the porcelain cover. By adoption of the abovementioned structure, a plurality of electroconductive rods can be arranged on one porcelain cover, and meanwhile, by means of a sealing structure in skillful design, the airtightness is stronger and safety and reliability are achieved.
Description
Technical field
The utility model relates to a kind of novel transformer lead collar tubular construction.
Background technology
At present, the transformer outlet sleeve pipe of using on the market mostly can only be fit to install a conducting rod; The conductive tabs of different potential then can only be installed remaining in addition according to demand and sleeve pipe occurred if desired, and the benefit of this mode is safe and reliable; Under the few situation of required current potential number of taps, be easy to fitting operation, but this mounting means needs the current potential tap quantity to be installed for a long time if run into; Then just cause the fuel tank volume of transformer to increase, cost is significantly gone up, and is not easy to install; Reliability also can descend, and influences outward appearance, and has potential safety hazard; Also have in addition in transformer, to add the load switch voltage regulating mode, but this mode cost is relatively too high, and can't uses big Current Regulation.
The utility model content
The utility model provides a kind of novel transformer lead collar tubular construction, and a project organization sleeve pipe is cleverly installed many conducting rods structure and sealing and rain cover structure, makes the problem of existence in the market to solve.
The utility model is to realize like this; A kind of novel transformer lead collar tubular construction comprises porcelain body, and with the porcelain of porcelain body Joint lid; Also comprise connecting and be arranged at the conducting rod that porcelain covers; The end that conducting rod stretches out the porcelain lid is provided with binding post, the also sheathed mounting flange in joint portion of porcelain body and porcelain lid, and the gap between mounting flange and porcelain body, the porcelain lid is filled with colloid; Said conducting rod stretches out porcelain lid end shield and is provided with rain cover, and said rain cover is connected with mounting flange; Said conducting rod and porcelain cover upper surface contact site are provided with exterior seal ring, near the exterior seal ring place clamp nut are installed on the conducting rod, and clamp nut is locked downwards, and exterior seal ring is pressed in conducting rod and porcelain cover upper surface contact site; Said conducting rod and porcelain lid lower surface contact site are provided with an annular table terrace, are provided with inner seal ring between said annular table terrace and the porcelain lid lower surface.
The colloid that fill in gap between said mounting flange and porcelain body, the porcelain lid is an epoxide-resin glue.
Said conducting rod is more than two or two, and the conducting rod that wherein connects porcelain lid mid portion is provided with hood; The current potential of said conducting rod can be the difference setting.
Preferably, said rain cover is processed for the epoxy glass fiber material.
Said porcelain body is provided with mounting flange, in order to connect transformer.
10～40.5kV scope inner oil filling type transformer outlet porcelain bushing with the outlet porcelain bushing of adorning two above different potentials conducting rods in the sleeve pipe all in protection range; Everyly insulator is partly resolved into porcelain lid help that with porcelain body last porcelain is covered two-sided processing and solve sealing problem, again gummed be assembled into integral body all in protection range.
The invention has the beneficial effects as follows:
1, many current potentials conducting rod and binding post, tap reduce volume;
2, the rain cover structure effectively prevents to leak, leak electricity;
3, can be generalized on other transformers and use, relate in particular to 10-40.5KV oil-filled transformer.
