Abstract
The utility model discloses a novel connecting structure of a transformer oil tank and a tank cover. Bolt holes are formed in the outer circle of the edge of the oil tank, the oil tank and the tank cover are connected by bolts and nuts through the bolt holes, 1-2 seal process grooves are formed in the inner circle tank edges of the bolt holes, and seal rubber strips are arranged in channels of the seal process grooves. The novel connecting structure is simple in structure and convenient to machine and design, the seal process grooves are adopted for sealing, so that seal performance is greatly improved, oil in a transformer is prevented from leaking, meanwhile, air, water, dust and the like are prevented from entering the oil tank, the aging rate of the transformer oil is slowed down, and the operation cycle of the transformer is increased.
Description
Technical field
The utility model relates to a kind of oil-filled transformer, is specifically related to the syndeton of a kind of oil tank of transformer and case lid.
Background technology
Oil-filled transformer is unshakable in one's determination and winding is immersed in the transformer in iknsulating liquid.Fuel tank by upper tank along being tightly connected with case lid, during connection, case along with case lid sealing surface on place diaphragm seal, utilize screw bolt and nut to realize sealing.This syndeton, after diaphragm seal is aging, can cause oil impregnate and air, moisture, dust etc. to enter fuel tank, causes oil quality deterioration, affects the efficient long-term safety operation of transformer.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of Novel oil tank of transformer and case lid syndeton that improves sealing property, reduces leakage of oil probability.
For achieving the above object, the technical solution adopted in the utility model is:
Novel oil tank of transformer and case lid syndeton, the outer ring on the case edge of fuel tank is provided with bolt hole, screw bolt and nut connects fuel tank and case lid by bolt hole, and the inner ring case of bolt hole, along being provided with 1 ~ 2 sealing technology groove, is provided with sealing joint strip in the conduit of sealing technology groove.
Above-mentioned Novel oil tank of transformer and case lid syndeton, the degree of depth of described sealing technology groove is 6 ~ 12mm, the thickness of described sealing joint strip is 4/3 times of sealing technology groove depth.
The beneficial effects of the utility model: the utility model is simple in structure, be convenient to fabrication design, adopt after the sealing of sealing technology groove, greatly promoted sealing property, prevented the oil seepage of transformer inside out, also avoided air, moisture, dust etc. to enter fuel tank, slowed down the aging speed of transformer oil, increased the cycle of operation of transformer simultaneously.
Accompanying drawing explanation
Fig. 1 is the vertical view of the utility model fuel tank.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the front view after the utility model fuel tank is connected with case lid.
Embodiment
As shown in Fig. 1 ~ Fig. 3, Novel oil tank of transformer and case lid syndeton, the case of fuel tank 5 is provided with bolt hole 1 along 4 outer ring, screw bolt and nut connects fuel tank and case lid 3 by bolt hole 1, the inner ring of bolt hole 1 is provided with two circle sealing technology grooves 2 along fuel tank edge, in the conduit of sealing technology groove 2, be provided with sealing joint strip, the thickness of sealing joint strip is 4/3 times of the degree of depth of sealing technology groove.Case is processed by planer-type milling machine along 4 sealing technology groove 2, and simple in structure being convenient to processed.
