Abstract
The utility model discloses a high-voltage heavy-current wire connection device for a mine. The high-voltage heavy-current wire connection device comprises a connector base, a wire connection bolt and a wire pressing device. The high-voltage heavy-current wire connection device is characterized in that the wire pressing device comprises a wire pressing block, a U-shaped plate, a gasket and a nut, wherein the gasket and the nut are suited on the periphery of the U-shaped plate, and the wire pressing block is fixedly connected with the U-shaped plate, so that the wire pressing device is formed as a whole; the complexity of sequential installation is avoided during wire connection, the cable pressing and connection can be firmer and more reliable, and electric discharge is not easy to happen.
Description
Technical field:
The utility model relates to the termination of power transmission cable, voltage 10KV especially, the big electric current termination of the following mining high-voltage of electric current 800A.
Background technology:
Along with the raising of coal mining automaticity, output increases, and electric energy use capacity increases.In order to satisfy energy-saving and cost-reducing requirement, the down-hole electric pressure improves constantly, and in carrying electric process, the application of high-voltage great-current product more and more widely.Wiring in the past adopts T shape piece, bolt, nut to add the distributing line ball mode of wiring packing ring more, and line ball was both inconvenient, also more loaded down with trivial details, and poor electric conductivity, was difficult for heat radiation, easily discharge.
The purpose of this utility model is to provide a kind of cable crimping the not only convenient but also firm big electric current termination of mining high-voltage.
The purpose of this utility model realizes by following design: the big electric current termination of a kind of mining high-voltage, constitute by junction block, connection bolt and cord grip three parts, it is characterized in that described cord grip is made up of line ball piece, U template, packing ring and nut, packing ring and nut sleeve are in U template periphery, line ball piece and U template are affixed, make cord grip integrated as a whole.
The two ends outward flanging that further scheme of the present utility model is described U template blocks nut.
Design of the present utility model has taken into full account easy-to-connect and requirement of explosion proof, is adapted to particular surroundings under the coal mine more, and electric clearance and creepage distance meet the relevant national standard requirement fully; When wiring, both avoided pursuing the loaded down with trivial details of part installation, made again that the cable crimping was more solid and reliable, be difficult for discharge.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of cord grip.
As depicted in figs. 1 and 2, the utility model provides a kind of voltage that is used for to 10KV, the mining product termination that electric current 800A is following, and this device is made of joint porcelain 1, connection bolt 2 and cord grip 3 three parts.Joint porcelain 1 is fired into one by pedestal and circular arc pillar, and its surface scribbles one deck purple enamel uniformly, and insulation property are good.Connection bolt 2 is processed by the copper rod of certain specification, and the upper end of connection bolt 2 has the U type groove of certain altitude, to make things convenient for the reliable connection of cable.Connection bolt fixes on the joint porcelain with the cement gel cementation.Cord grip design after the improvement has taken into full account easy-to-connect and requirement of explosion proof, be adapted to particular surroundings under the coal mine more, in conjunction with shown in Figure 3, cord grip 3 is by line ball piece 4, U template 5, packing ring 6 and nut 7 four parts are formed, packing ring 6 and nut 7 are enclosed within U template 5 peripheries, the two ends outward flanging of U template 5 blocks nut 7, line ball piece 4 and U template 5 bottoms are riveted together, thereby make four to constitute inseparable integral body, line ball piece 4 and U template 5 all adopt copper structure, except playing the line ball effect, have strengthened electric conductivity simultaneously, be easier to heat radiation, reduced contact electricity sun.
