Abstract
The invention discloses a bus connection device, which comprises epoxy resin bodies, a rubber body and a fitting, wherein the fitting is composed of a copper bar and contact springs; the top part of each epoxy resin body is provided with a through hole; through adopting the through hole with the specification of phi 39 to be matched with the copper bar with the specification of phi 46 and the contact spring for use, defects that a small contact area and small effective current passing ability existing in side extension connection can be effectively solved. Due to the rubber body, the anti-tracking ability of an outdoor product can be effectively improved, the hydrophobicity is improved, design of a semiconductive layer is increased, a role of effectively shielding an electric field is played, and the safe operation level of the cable network is improved. Due to the contact springs, the structure is simplified, the mounting is convenient, multiple contact points are provided, the conductive performance is good, the electric field is uniformly distributed, the contact deformation range is large, the contact pressure is constant, the wear is small, and the use cycle is long.
Description
Technical field
The present invention relates to a kind of connection equipment of insulated switch cabinet, more particularly to a kind of bus connecting device.
Background technology
At present existing bus connection scheme is divided into sideways expansion with top extension two schemes.
Sideways expansion connection scheme is exactly to install bus-bar insulator, the bus insulation of the first cabinet in side in the side of two adjacent cabinets
Bus tie is installed on son, then makes another cabinet body move and draw close fastening, complete the bus connection of cabinet and cabinet；Top is expanded
Exhibition connection scheme is exactly that extension sleeve pipe is first installed at the top of cabinet, then is drawn close after fastening to the cupboard for wanting simultaneously cabinet, and at top elder generation is inserted in
Prefabricated bus, and fasten successively.
Sideways expansion scheme median generatrix insulator conductor is adoptedOrOrRed copper bar；What bus tie was adopted
It is to be bundled the conductor for being formed by spring by multi-disc (most 12) copper contact blade, holds the copper conductor in bus-bar insulator tightly
Conduction is contacted with bus-bar insulator conducting rod by 12 conductiving points on gold utensil, the shortcoming of this structure is exactly that contact area is little, is had
Effect overcurrent capability is less than 630A.
Top expansion scheme is adopted because of conductorRed copper bar, effective overcurrent can reach 1250A.But gas-insulated switch
During cabinet long-play, because of gas tank gas leakage, box house SF6 or N2 gas density reduces, and just occurs main bus-bar to gas
Case metal wallboard discharges, punctures so as to cause the generation of security incident.
The content of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of contact area is big, the bus of overcurrent capability can be effectively improved
Attachment means.
To achieve these goals, one aspect of the present invention is：
A kind of bus connecting device, it is characterised in that including epoxy resin body, rubber body and gold utensil, the gold utensil is located at rubber
In vivo, the epoxy resin body is two to glue sheet, and is respectively fitted over the two ends of rubber body, and the gold utensil is by red copper bar and fingertip
Spring is constituted, and the fingertip spring is set in the two ends of red copper bar, and the side of the epoxy resin body is provided with full skirt, the full skirt
With this body by integral forming of epoxy resin, the top of the epoxy resin body is provided with through hole, conducting rod, institute is provided with the through hole
State conducting rod to be enclosed within one end of gold utensil, the conducting rod is embedded in rubber body, the epoxy resin body is provided with least one
Individual copper insert.
Used as the preferred of above-mentioned technical proposal, the rubber body outside is provided with semi-conductive layer.
As the preferred of above-mentioned technical proposal, the middle part outside connection ground wire of the rubber body.
Used as the preferred of above-mentioned technical proposal, the red copper bar specification is
Used as the preferred of above-mentioned technical proposal, the specification of the through hole is
From above-mentioned technical proposal as can be seen that the present invention by adopt specification forThrough hole withRed copper bar and fingertip spring
Use cooperatively, effectively solve contacting surface present in sideways expansion connection and accumulate little, the little shortcoming of effective overcurrent capability.Rubber body
The tracking-resistant for effectively improving outdoor products plays trace ability, improves its hydrophobicity, and rubber body increased the design of semi-conductive layer and rise
The effect of effective shielding electric field is arrived, so as to improve the safety operation level of cable system.Simplify structure using fingertip spring,
Easy for installation, contact point is more, conduct electricity very well, Electric Field Distribution is uniform, juxtaposition metamorphose scope is larger and pressure that is contacting is constant, mill
The advantages of damaging little, usage cycles are long.
