Description
Technical field
The utility model relates to a kind of electric railway and is used to logical line modified model isolating switch, is specifically related to a kind of electric railway and is used to logical line usefulness, and the modified model isolating switch that deciliter circuit is used is arranged in the uncharge situation of voltage at circuit.
Background technology
At present, known railway isolating switch is to be made of pillar, current-carrying part and outlet terminal.When being connected with high-voltage conducting wires, need to be equipped with separately device clamp or binding post, increased tie point, and outlet terminal is that ball-type is connected with conducting electricity the contact of plug-in strip, the contact imprecision, contact area is little, thereby resistance is increased, and consumes electric energy, during construction, owing to need to install transitional facility additional, personnel's labour intensity increases, Efficiency Decreasing.General outlet terminal is to be welded by cast copper product or copper coin, and inherent quality is unstable, and equipment goes wrong easily, causes potential safety hazard to rail track, and security performance is not high.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can not only reduce resistance, improves security performance, and logical line modified model isolating switch is used in the electric railway that can reduce workmen's labour intensity.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: logical line modified model isolating switch is used in a kind of electric railway, comprise base, the first composite post insulator, the second composite post insulator, gangbar, first goes out line component, second goes out line component and trigger installation, described the first composite post insulator is installed on one side of described base, described the second composite post insulator is installed on the another side of described base, described the first composite post insulator is connected by gangbar with the second composite post insulator, described first goes out line component is connected with described the first composite post insulator, described second goes out line component is connected with described the second composite post insulator, and described first goes out line component and second goes out line component and be connected by trigger installation.
The beneficial effects of the utility model are: reduce resistance, reduce electric energy loss; Improve the safe operation coefficient of circuit, reduce labour intensity, improve installation effectiveness.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described first goes out line component and second goes out line component and includes copper bar plug-in strip, ball, cable clamp type binding post and spring, described copper bar plug-in strip is connected with described cable clamp type binding post under the pressure-acting of spring, described ball is connected with described copper bar plug-in strip, and described copper bar plug-in strip is connected with described trigger installation.
Adopt the beneficial effect of above-mentioned further scheme to be, the cable clamp type binding post is directly by the shape of red copper row punching forming apparatus wire clamp, make wire clamp and the conduction plug-in strip boss that stamps out, rely on the pressure close contact of spring, the contact-making surface fine finishining of cable clamp type binding post and conduction plug-in strip increases contact area, improve the tightness of contact, and the cable clamp type binding post of whole punching press can be avoided the internal flaw of cast copper or welding, thereby effectively reduces resistance.Through measuring, be reduced to below the 100 μ Ω more than the 200 μ Ω of galvanic circle resistance by original type.The cable clamp type binding post of whole punching press, its stable material quality is reliable, can effectively avoid the shrinkage porosite, pore etc. of cast copper class or welding class outlet terminal to conceal defects, and its strength ratio outlet terminal in the past significantly improves, thereby improves the security performance of equipment.
In addition, the cable clamp type binding post directly contacts with high-voltage conducting wires, reduces tie point, has reduced the use of transitional facility, and is quick and easy for installation, reduces workmen's labour intensity.
