Abstract
The utility model relates to an outdoor high-voltage vacuum demarcation load switch which comprises a shell, a current transformer, an operation mechanism, a hoisting device and a single-pole switch, wherein the current transformer is used for sampling the current; the single-pole switch is accommodated in the shell and three phases of the single-pole switch are same in structure; the single-pole switch comprises an isolating-end insulating shaft, an isolating cutter, a moveable contact, a spindle and an arc extinguishing chamber; one end of the isolating cutter is fixedly mounted on the isolating-end insulating shaft and is electrically connected with the moveable contact in a flexible coupling form; the other end of isolating cutter is in contacting connection with an inlet wire pillar; the spindle can drive the moveable contact to be in contacting connection with an outlet wire pillar in the vacuum arc extinguishing chamber; the operation mechanism respectively acts on the isolating-end insulating shaft and the spindle; and the operation mechanism is used for driving the isolating-end insulating shaft and the spindle to respectively drive the isolating cutter and a main contact to move, so as to switch off a faulty line by the demarcation load switch and isolate from the demarcation load switch. The outdoor high-voltage vacuum demarcation load switch has the characteristics of compact structure, small volume, convenience in mounting, strong switching capacity and excellent safety property.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage vacuum demarcation load switch.
Background technology
Demarcation load switch is a kind of responsibility separation of the 10KV of being installed in overhead distribution, can excise automatically and isolate have single phase ground fault, the circuit of phase fault.In the existing demarcation load switch, the release and the isolating switch that excise usefulness as circuit adopt split type mounting structure, make demarcation load switch seem huge and heavy.In addition, the matching mechanism more complicated of auto-cutout and isolation, easy error causes the serious person and device security accident.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provides a kind of auto-cutout mechanism and isolating switch to adopt integrated design, and is simple in structure, the outdoor high-voltage vacuum demarcation load switch of reliable operation.
For realizing above-mentioned purpose; The utility model adopts a kind of like this outdoor high-voltage vacuum demarcation load switch; Current transformer, operating mechanism, the boom hoisting that comprises housing, electric current is sampled and be contained in the single-pole switch that three-phase in the described housing has same structure; The described single-pole switch of three-phase extends three inlet wire post and three outlet column that are with insulating sleeve that are with insulating sleeve to the both sides of described housing respectively; Described single-pole switch comprises isolation end insulation axle, isolation knife, moving contact, main shaft and vacuum interrupter; One end of described isolation knife is fixedly installed in described isolation end insulation axle and goes up and be electrically connected with moving contact through being flexible coupling; The other end of described isolation knife is connected with described inlet wire post contact, and described main shaft can drive described moving contact and in described vacuum interrupter, be connected with described outlet column contact, and described operating mechanism acts on described isolation end insulation axle and described main shaft respectively.
Especially, described current transformer and sealing gasket matching and fixing are installed on the sidewall of described housing inlet wire side.
Especially, described housing both sides are provided with the cable protection frame respectively.
Compared with present technology, the beneficial effect of the utility model is embodied in: drive isolation end insulation axle and main shaft by operating mechanism, drive the motion of isolation knife and main contact respectively, make demarcation load switch excision faulty line, and isolated with it.The utlity model has compact conformation, volume little, be convenient to install, simultaneously, switch deciliter ability is strong, the characteristics that security performance is good.
