Description
Technical field
The present invention relates to wall bushing, specifically, be the wall bushing that a kind of dirt exclusion capabilities is strong.
Background technology
Wall bushing is the important coupling part between transformer and distribution line, connects main transformer low-pressure side lead-out wire and switch gear room.When electric current flows through main busbar, a magnetic field can be excited on the wall bushing plate being fixed on body of wall, and produce eddy-current loss.Eddy-current loss can increase along with bus operating current and be increased dramatically, and makes wall bushing plate generate heat.During summer peak meeting, this is particularly problematic, has a strong impact on current-carrying capacity and the service behaviour of electrical equipment, normal work, the safe operation of whole piece circuit and the reliable power supply of wall bushing body of bus, even jeopardizes personal safety.
Wall bushing under the conditions of prior art does not has line up to arrange dust guard, causes dust, aqueous vapor easily to be piled up at the mouth of pipe so that mouth of pipe environment becomes moist through, and produces potential threat.
Summary of the invention
It is an object of the invention to provide a kind of sleeve pipe that contributes to lower the temperature, improve the wall bushing that the dirt exclusion capabilities of sleeve pipe working environment is strong.
The present invention is achieved through the following technical solutions: the wall bushing that a kind of dirt exclusion capabilities is strong, sleeve pipe, ring flange and conductor including insulation, ring flange is fixing to be fastened in the middle part of sleeve pipe, conductor is arranged in sleeve pipe, sleeve pipe is provided with several full skirts, sleeve pipe two ends are sealed and installed with dust-proof end cap, and conductor passes dust-proof end cap, and the diameter of dust-proof end cap is more than the diameter of full skirt.
The two ends of described conductor are provided with connecting plate.
Described sleeve pipe is threaded connection with dust-proof end cap, and dust-proof end cap is insulated end cover.
Described dust-proof end cap is connected with the end part seal of sleeve pipe built with sealing ring, sealing ring.
Described ring flange is provided with several fin, leaves gap between fin.
Described ring flange is the ring flange that manganese low magnetic steel is made.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention is prevented from dust, aqueous vapor etc. and enters in sleeve pipe by arranging dust-proof end cap thus cause potential danger, improves the working environment of sleeve pipe, is conducive to extending its service life, and avoids producing creepage phenomenon；
(2) present invention is by arranging fin, it is possible to increasing heat radiation area, the efficiency of raising heat transfer, is conducive to improving the heat dispersion of sleeve pipe, improves the working environment of sleeve pipe, it is to avoid the current-carrying capacity of bus is affected, is conducive to extending the service life of sleeve pipe；
(3) present invention is by leaving gap between fins, be conducive to reducing the magnetic field range of its vicinity, the caloric value produced because of eddy-current loss can be reduced with this, and by using manganese low magnetic steel to make ring flange, the magnetic field intensity of its vicinity can be reduced, also the caloric value produced because of eddy-current loss is beneficially reduced, in order to improve the working environment passed through.
