Description
Technical field
The invention belongs to the high voltage electric equipment field, relate in particular to and a kind ofly direct current can be accessed the isolating switch that ultra-high-tension power transmission line carries out ice-melt.
Background technology
Along with developing rapidly of economy, the also sharply increase of demand to electric power needs a large amount of high pressure or ultra high voltage to transmit route and satisfies electricity needs.But when meeting with in the winter time the weather such as sleet, have icing in delivery guidewire, icing has larger weight, can cause mechanical failure to the wire in the power transmission line, various gold utensil and steel tower etc.; Greatly reduce the useful life of transmission line; Can cause the phenomenon of broken string, collapse of iron tower when serious, cause the power failure of large face and cause larger security incident.In existing power technology, often adopt the direct current de-icing technology to carry out deicing, its principle is Ice-glazed transmission line to be applied DC power supply make the circuit heating reach purpose except icing.In practice, generally after having a power failure, high-tension line by isolating switch DC power supply is linked in the ac high-voltage conveying circuit.The isolating switch that existing ice-melt is used generally all is the horizontally openable formula, horizontally openable formula isolating switch one end links to each other with dc wire, the other end is connected ultra-high-tension power transmission line, but this isolating switch overall dimension is larger, structure is comparatively complicated, floor space is large, needs larger fabricating yard, and installation cost is higher.
Summary of the invention
Purpose of the present invention is the shortcoming that overcomes prior art, and a kind of simple and reasonable, ice-melt isolating switch that floor space is little is provided.
For solving the problems of the technologies described above, concrete technical scheme of the present invention is as follows:
A kind of ice-melt isolating switch is characterized in that: comprise three single-stage isolated switches that are linear arrangement, described each single-stage isolated switch is by the bottom successively shore supports of correspondence;
Described single-stage isolated switch comprises conductive seat, upper supporting column insulator and fixed contact; Described fixed contact is connected on the high-voltage connection terminal of described upper supporting column insulator top;
Establish conductive arm on the described conductive seat, by moving contact and the fixed contact contact separation on the driving of the link gear in the described conductive seat conductive arm; The direct current binding post that is connected with described conductive arm is arranged on the described conductive seat;
Link gear in one three-phase ganged bar and each conductive seat is connected;
Also comprise a motor operation mechanism, link by insulated tension pole and single-stage isolated switch, be connected with the three-phase ganged pull bar by transmission crank arm again, breaking-closing operating motion when carrying out three-phase isolation switch.
Further, described conductive seat below also is provided with the porcelain vase base, is supported by bottom shore.
Further, described three single-stage isolated switches are equidistant layout.
Further, described motor operation mechanism installs transition bracket by mechanism and hangs on intermediate studdle.
