Description
Technical field
This utility model relates to wall bushing, specifically, is the wall bushing that a kind of dirt exclusion capabilities is strong.
Background technology
Wall bushing is the important coupling part between transformator 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.
Utility model content
The purpose of this utility model is 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.
This utility model 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 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.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) this utility model 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) this utility model 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) this utility model 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.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1:
As shown in Figure 1, Figure 2, Figure 4 shows, in the present embodiment, the wall bushing that a kind of dirt exclusion capabilities is strong, including sleeve pipe 2, ring flange 3 and the conductor 1 of insulation, ring flange 3 is fixing to be fastened in the middle part of sleeve pipe 2, and conductor 1 is arranged in sleeve pipe 2, sleeve pipe 2 is provided with several full skirts 21, sleeve pipe 2 two ends are sealed and installed with dust-proof end cap 5, and conductor 1 is through dust-proof end cap 5, and the diameter of dust-proof end cap 5 is more than the diameter of full skirt 21.
In the present embodiment, the two ends of described conductor 1 are provided with connecting plate 7, facilitate conductor 1 to be connected on circuit with this.
In the present embodiment, described sleeve pipe 2 is threaded connection with dust-proof end cap 5, and its bonding strength is high, and dust-proof end cap 5 can be changed, and is also beneficial to change or take out conductor 1, and dust-proof end cap 5 for insulated end cover and can be tightly connected with conductor 1.
In the present embodiment; described dust-proof end cap 5 is built with sealing ring 6; sealing ring 6 is connected with the end seal of sleeve pipe 2; simultaneously; sealing ring has certain elasticity and can be compressed, and when sleeve pipe 2 is pre-buried on body of wall, screws dust cover 5 and is allowed to compresses seal 6; improve sealing and make dust cover 5 contact with body of wall, in being possible to prevent big granule or insecticide to enter into the gap between dust cover 5 and body of wall, sealing ring being caused damage.
As it is shown on figure 3, in the present embodiment, described ring flange 3 is provided with several fin 4, leaves gap 8 between fin 4, the magnetic field range being conducive to reducing its vicinity with this, and the caloric value produced because of eddy-current loss can be reduced.
In the present embodiment, the ring flange that described ring flange 3 is made for manganese low magnetic steel, by using manganese low magnetic steel to make ring flange, it is possible to reduce the magnetic field intensity of its vicinity, also the caloric value produced because of eddy-current loss is beneficially reduced, in order to improve the working environment passed through.
