Description
Technical field
The utility model 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.
Utility model content
The technical problems to be solved in the utility model is that the also cabinet bus of prior art is difficult to have insulation simultaneously, the defect of simple installation advantage, and a kind of also cabinet bus that has good insulation effect and be convenient to install is provided.
The utility model is to solve 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.
Positive progressive effect of the present utility model is: make also cabinet bus have better insulation effect, and be convenient to install.

Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment
The utility model 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 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 embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these changes and modification all fall into protection range of the present utility model.
