Description
Technical field
This utility model relates to controller switching equipment technical field, is specifically related to a kind of bushing for transformer.
Background technology
Transformator be the principle utilizing electromagnetic induction to change the device of alternating voltage, main member is primary coil, secondary
Level coil and iron core (magnetic core).Major function includes that (magnetic saturation becomes for voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing
Depressor) etc..Can be divided into by purposes: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry type become
Depressor, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc..
Bushing shell for transformer is the primary insulation device outside transformer tank, and the lead-out wire of Transformer Winding has to pass through insulation sleeve
Pipe, makes to insulate between lead-out wire and between lead-out wire and transformer case, plays the effect of fixing lead-out wire, therefore transformator simultaneously
Sleeve pipe has important function during the use of transformator.
At present, in use, there are some defects, such as in the bushing shell for transformer on market: casing joint is overheated, seepage
Oil, medium or oil dielectric loss exceed standard and bottom shielding of bushing loose contact etc., it addition, bushing shell for transformer is due to long-time exposed use, easily
There is laying dust, cause leakage of current, threaten personal safety, and, operational risk is installed greatly, skidproof effect is poor, to operator
Requiring height, can not operate at the vile weather such as wind, rain, installation difficulty is big.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the drawbacks described above that prior art exists, it is provided that a kind of exhausted
Edge effect is good, is difficult to laying dust, the bushing for transformer easily installed.
This utility model solves its technical problem and be employed technical scheme comprise that, a kind of bushing for transformer, including absolutely
Edge porcelain body and seal plug, described seal plug is located at the top of insulating ceramic, and the bottom of described insulating ceramic is provided with base, institute
The internal diameter stating base is suitable with the external diameter of insulating ceramic, and the periphery of base is provided with groove, the lower shape of described insulating ceramic
For cylinder, the shaped upper part of insulating ceramic is round platform, and the shaft section of round platform is isosceles trapezoid, and the base angle of isosceles trapezoid is 16-
30 °, the bottom of insulating ceramic is cased with plural number block ceramics, and the middle part of insulating ceramic is provided with wiring hole.
Further, the bottom of described insulating ceramic is cased with 6 pieces of ceramics, and the arrangement mode of described ceramics is equidistantly arrangement.
Further, described seal plug is provided with external screw thread, and the top of described insulating ceramic is provided with female thread, seal plug
External screw thread is suitable with the top female thread of insulating ceramic.
Further, the arrangement mode of described groove is equidistantly arrangement.
Further, the internal diameter of described base and the external diameter of insulating ceramic are identical.
Compared with prior art, this utility model simple in construction, designs ingenious；Insulation effect is good, and sealing property carries significantly
Height, makes the dependability of transformator and stability improve, extends the life-span of transformator, reduces fault rate, less safeguards
Workload, seal plug is located at the top of insulating ceramic, and the internal diameter of base is suitable with the external diameter of insulating ceramic；Can effectively prevent
Laying dust, it is to avoid cause leakage of current, safety improves, and the shaped upper part of insulating ceramic is round platform, and the shaft section of round platform is isosceles
Trapezoidal, the base angle of isosceles trapezoid is 16-30 °；Easy to use, good antiskid effect, reduce workman's difficulty when mounted, base
Periphery be provided with groove.
