A sealing ring is used for sealing between the first insulating layer and the second insulating layer. The cabinet combining bus has advantages of good insulating effect and convenient mounting.
Description
Technical field
The present invention relates to a kind of wire, particularly a kind of and cabinet bus.
Background technology
Minitype high voltage ring main unit cabinet bus belong to the important electric component of a circuit, bear the task of collecting, carrying and distributing electric energy in transformer and distribution station.Due to and cabinet bus be in operation, there is very large electric current to pass through, when short circuit, bearing very large heating and dynamo-electric effect, therefore, must reasonably select bus material, cross sectional shape, cross-sectional area and connected mode to meet the technical requirement of electric equipment safety and economic operation.
What the also cabinet bus of most all adopted is copper bar, and these copper bars are are only just directly installed and used through simple processing and surface treatment.Copper bar is made bus construction convenience, ampacity is large, conductivity is better, processing cost is lower.But copper bar is exposed in air, in long-term use procedure, because of the thermal effect of electric current, copper bar temperature raises, and accelerates copper bar surface oxidation, and the copper bar resistance after oxidation increases, and electric current thermal losses on copper bar is further increased, and causes circuit power consumption to increase.Especially in the place that has chemical corrosion, be oxidized more rapidly, destroy the conductivity of bus, have influence on the orderly function of transformer and distribution station.
Although Ye You company has designed a kind of bus at the casting insulated material of copper pipe outer surface, but the shortcoming of this bus is that inconvenience is installed, in the time that also cabinet is installed, to adopt from the copper pipe of bus inside and penetrate reinforcing bar and the next fastening mode fixed support bus of two ends nut, and the length of reinforcing bar is normally limited, in the time running into a fairly large number of switch cubicle needs cabinet, this bus is just difficult to use.
Summary of the invention
The technical problem to be solved in the present invention is, in prior art and cabinet bus insulation weak effect, inconvenient defect is installed, provide a kind of there is good insulation effect and be convenient to install and cabinet bus.The present invention solves above-mentioned technical problem by following technical proposals:
A kind of also cabinet bus, comprises sub-line parts, bus parts, and its feature is: described sub-line parts comprise solid copper bar, are set in the first insulating barrier outside described solid copper bar, and one end of described solid copper bar has the screwed hole mating with high-voltage board end of incoming cables; Described bus parts comprise a copper pipe, are set in the second insulating barrier outside described copper pipe, and one end of described copper pipe has the screw mounting hole mating with high-voltage board end of incoming cables, the nested at least one spring touch finger of inwall of the other end of described copper pipe; Between described the first insulating barrier and described the second insulating barrier, seal with sealing ring.Owing to having adopted described spring touch finger, even if make the out-of-flatness of high-voltage board installed surface, and cabinet bus also can be in the scope of 5 millimeters automatic capturing, contact is good.
Preferably, the material of described solid copper bar, described copper pipe is red copper.This make and the electric conductivity of cabinet bus better.
Preferably, described the first insulating barrier, described the second insulating barrier are epoxy resin layer.
Preferably, the thickness of described epoxy resin layer is 9mm.
Preferably, described screwed hole is M10 screwed hole.Electric power and operating state when M10 screw thread has met full capacity drop-out current are completely stressed at full capacity.
Preferably, the quantity of described spring touch finger is two.Make described sub-line parts and described bus parts there is better conductivity.
Preferably, the electroplate of described spring touch finger.Make described sub-line parts and described bus parts there is better conductivity.
Preferably, on described spring touch finger, scribble conductive paste.Make described sub-line parts and described bus parts there is better conductivity.
Raw materials used all commercially available the obtaining of the present invention.
Positive progressive effect of the present invention is: a kind of also cabinet bus that has good insulation effect and be convenient to install is provided.

Embodiment
Mode below by embodiment further illustrates the present invention, but does not therefore limit the present invention among described scope of embodiments.The experimental technique of unreceipted actual conditions in the following example, according to conventional method and condition, or selects according to catalogue.
Embodiment
The invention provides a kind of and cabinet bus.Also cabinet bus is assembled by sub-line parts 1, bus parts 2.Copper pipe 21 in solid copper bar 11, bus parts 2 in sub-line parts 1 can be formed by circular red copper materials processing.Compare copper bar or other cross sectional shape electric conductors, circle can obtain larger conductive area, and saves installing space.When assembling, there is screwed hole 13(one end of sub-line parts 1 such as M10 screwed hole), one end of bus parts 2 has the screw mounting hole 23 can be fastening with two high-voltage boards respectively, guarantees electric conductor good contact.When and when cabinet, sub-line parts 1 insert in bus parts 2, contact conducting with the spring touch finger 24 in bus parts 2.In order to obtain better conductive effect, can use two spring touch fingers 24, can be silver-plated on spring touch finger 24, also can smear conductive paste.Owing to having adopted spring touch finger 24, when the out-of-flatness of high-voltage board installed surface, and cabinet bus has self-rectification function, automatic capturing within the scope of 5mm, and contact is good.This mode is easy for installation, saves material, conducts electricity very well, and loop resistance is little, and moving hot property is stable.Between sub-line parts 1 and bus parts 2, seal with sealing ring 3, play the effect of insulation.The surface of solid copper bar 11 becomes the first insulating barrier 12 by the good poured with epoxy resin of insulation property, and the surface of copper pipe 21 becomes the second insulating barrier 22 by poured with epoxy resin.The compressive resistance of epoxy resin is at 18kV/mm, as and the epoxy resin minimal thickness of cabinet bus be about 9mm, met the insulating requirements of ring main unit completely.Compare the air insulation that safe distance is greater than 125mm, adopt the just miniaturization more of epoxy resin solid dead ring net cabinet, compact conformation, bulking value reduces greatly, and production and processing is transported easier for installationly, has also saved the construction cost of transmission & distribution electric substations simultaneously.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these execution modes, but these changes and modification all fall into protection scope of the present invention.
