Description
Technical field
This utility model relates to the bus connection member technical field of switchgear, particularly relates to a kind of bus set through walls
Pipe.
Background technology
Along with the high speed development of electric power, switchgear assembly is progressively towards high voltage, miniaturization, and switchgear is one
Planting combined electric appliance, collection chopper, on-load switch, disconnecting switch, bus and corresponding measurement, control are installed on a rectangle
In metal safe.Safety in production and the reliability service of electrical network are all played an important role by the quality of switch cubicle performance, along with answering electricity consumption
, easily there is insulation fault, bus set through walls in the rising of pressure grade and the miniaturization of volume at switch cabinet bus wall bushing
Electric Field Distribution at pipe is uneven, and the insulant of existing bus wall bushing is susceptible to local ageing, causes insulating capacity
Decline, time serious, cause bus and switch cabinet body generation electric discharge phenomena, affect system worked well, the peace of harm staff
Entirely.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is to improve prior art, it is provided that
A kind of bus wall bushing, solves bus wall bushing poor insulativity traditional in current technology, and service life is short, is susceptible to
Electric discharge phenomena, the problem of safety in utilization difference.
For solving above technical problem, the technical solution of the utility model is:
A kind of bus wall bushing, including insulating cylinder, it is characterised in that offer bus via in described insulating cylinder, female
In line via, device conductive core forms sleeve structure, and bus via is rectangular opening, and conductive core is and bus via same shape
Cross section, the cross section entirety of insulating cylinder is rectangular, and the periphery of insulating cylinder is also provided with adpting flange.Mother described in the utility model
Line wall bushing simple in construction, designs the structure of insulating cylinder according to the structure of conductive core, and the radiating condition of rectangular conductive core is relatively
Good, there is certain mechanical strength, it is simple to fixing and connect, the insulating cylinder of rectangle is meeting the Electric Field Distribution of rectangular conductive core
In the case of, volume can be effectively reduced, reduce the material made needed for insulating cylinder, reduce cost of manufacture.
Further, described bus via is the rectangular opening that corner carries out fillet process, at the corner angle of rectangular conductive core
The electric field pole at place is uneven, and the excessive Discharge Phenomena of electric field intensity causes insulating cylinder aging too fast, has a strong impact on insulating properties,
Therefore conductive core is set to corner angle and carries out the rectangle of fillet process by this utility model, bus via is set to fillet square simultaneously
Shape hole, effectively reduces the electric field intensity of corner, less than the critical field strength of air breakdown, improves safety in utilization, extends insulation
The service life of cylinder.Aging and electric discharge phenomena the basic reason of bus wall bushing minor insulation is not the insulation energy of insulant
Power is not enough, but the electric-field intensity distribution of conductive core edges and corners is the most uneven causes the air gap discharge, uses fillet process, subtracts
The possibility of apiculus electric discharge.
Further, the cross section of described insulating cylinder is the rectangle that corner carries out fillet process, suitably reduces insulating cylinder
Wall thickness insulating properties will not be impacted, moreover it is possible to reduce cost.
Further, axially disposed some shirt rims on the outer wall of described insulating cylinder, shirt rim is around insulating cylinder
Chimb, increase creep age distance, improve insulating properties.
Further, described adpting flange is rectangular, it is simple to install location.
Further, described insulating cylinder and adpting flange are by epoxy resin one moulding by casting, and make efficiency is high, structure
Intensity is high, and stability in use is good.
Compared with prior art, this utility model advantage is:
Bus wall bushing simple in construction described in the utility model, effectively reduces the Electric Field Distribution of conductive core edges and corners not
Uniformity, it is to avoid electric field intensity is excessive causes the air gap electric discharge to make the local quick aging of bus wall bushing, extends
In service life, ensure effective insulating properties, save insulant, reduce cost, improve safety in utilization, it is ensured that the normal work of system
Make, the life security of safeguard work personnel.
Accompanying drawing explanation
Fig. 1 is axial cross-sectional views of the present utility model；
Fig. 2 is end face structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Disclosed in this utility model embodiment, a kind of bus wall bushing, effectively reduces the non-uniform electric of bus
Property, it is to avoid the excessive insulant local quick aging causing bus wall bushing of electric field intensity, it is effectively improved line wall bushing
The insulating properties of insulant, increase the service life, improve safety in utilization, it is to avoid electric discharge phenomena, safeguard work people occur
The life security of member.
As depicted in figs. 1 and 2, a kind of bus wall bushing, including insulating cylinder 1, in described insulating cylinder 1, offer bus mistake
Hole 2, in bus via 2, device conductive core forms sleeve structure, and bus via 2 carries out the rectangular opening of fillet process for corner, leads
Battery core is and the cross section of bus via 2 same shape, uses fillet to process, reduces the possibility of point discharge, be prevented effectively from electric discharge
Phenomenon causes insulating cylinder 1 local ageing, ensures that bus wall bushing has the insulating properties of long stable effect, insulating cylinder 1 transversal
Face is the rectangle that corner carries out fillet process, and insulating properties will not be impacted by the wall thickness suitably reducing insulating cylinder 1, it is possible to reduce
Making the material usage of insulating cylinder 1, thus reduce the cost of bus wall bushing, the periphery of insulating cylinder 1 is also provided with connection method
Blue 3, adpting flange 3 is rectangular, and insulating cylinder 1 and adpting flange 3, by epoxy resin one moulding by casting, manufacture efficiency high, structure
Intensity is high, and service life is long, and axially disposed some shirt rims 4 on the outer wall of insulating cylinder 1, shirt rim 4 be cincture insulating cylinder 1
Chimb, increases creep age distance, improves insulating properties.
Below it is only preferred implementation of the present utility model, it is noted that above-mentioned preferred implementation should not regard
For to restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For
