Description
Technical field
The utility model relates to a kind of outdoor high-voltage isolating switch.
Background technology
Isolating switch is that a kind of equipment that will overhaul or circuit and power supply separate with an obvious cut-off point, to guarantee the switch of maintainer and device security.General, isolating switch comprises the turnover line terminal block that is connected with lead, main contact, clavate insulation column, ground connection plug-in strip contact, ground connection plug-in strip and in order to guarantee two clavate insulation columns while backward rotation gangbar when deciliter action.When the needs separating brake, operating mechanism drives gangbar through the operator vertical links and makes two clavate insulation column backward rotation, makes the main contact disjunction, and the cutter vertical links drives ground connection plug-in strip and ground connection plug-in strip contact closure through ground by operating mechanism again.Because the both sides of isolating switch all might be connected with the bus section and the bus equipment of tool power supply, therefore need ground connection plug-in strip system all be set at the turnover line terminal block end of isolating switch.Existing isolating switch, deciliter action drive mechanism more complicated of two ground connection plug-in strip systems and operator, and move unreliablely, make the safety of products performance reduce greatly.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and a kind of simple in structure, reliable outdoor high-voltage isolating switch is provided.
For realizing above-mentioned purpose, the utility model adopts a kind of like this outdoor high-voltage isolating switch, comprises that three-phase has the single-pole isolator of same structure; Described single-pole isolator comprises left junction block and the right junction block that is installed on respectively on the two insulated pillars; Be fixed on the left plug-in strip on the described left junction block, be fixed on the right plug-in strip on the described right junction block, and base; Drive the operator vertical links by operating mechanism; Make described two insulated pillars backward rotation simultaneously through connecting lever, gangbar, described single-pole isolator also comprises two ground connection plug-in strip systems, and described pair of ground connection plug-in strip system comprises left ground connection plug-in strip contact and left ground connection plug-in strip; And right ground connection plug-in strip contact and right ground connection plug-in strip; Drive two ground cutter vertical links by operating mechanism, the cutter interphase connecting rod draws respectively with right ground cutter interphase connecting rod through ground, a left side, makes described left ground connection plug-in strip do a deciliter action with corresponding described left ground connection plug-in strip contact of going up mutually and right ground connection plug-in strip contact respectively with described right ground connection plug-in strip.
Especially, ground, described left side cutter interphase connecting rod is connected with the two ends of two ground connection gangbar respectively with described right ground cutter interphase connecting rod.
Compared with present technology; The beneficial effect of the utility model is embodied in: under the effect of ground, left side cutter interphase connecting rod and right ground cutter interphase connecting rod; Left plug-in strip on the three-phase single-pole isolator or right plug-in strip are closed with corresponding left plug-in strip grounding contact of going up mutually or right plug-in strip grounding contact respectively, disjunction; The drive mechanism of this product is fairly simple, and is reliable.Simultaneously, two ground connection gangbar can guarantee that ground, left side cutter interphase connecting rod and right ground cutter interphase connecting rod link simultaneously, and after isolating switch broke off, two grounding systems put into operation simultaneously, adopted the physical mechanism interlocking, made two grounding systems safer.
