Further, for realizing releasing the sulfur hexafluoride gas within cover body, this on-load switch also includes vent valve, draws from cover body interior and cover body is built integral.
Further, driving axle through drive link one end central authorities, the fixed connecting end of drive link and driving axle is to the hinged end of drive link Yu curved rod, and the size of drive link is gradually reduced, the drive link transmission better effects if of this structure.
Further, in order to realize observing the structure in portion in seal closure body, airtight cover body is provided with at least one observation window, and viewing glass sheet seals and is located on observation window.
Further, the one end stretched out outside cover body for protection on-load switch and whole power system, A contact and/or B contact is connected to fuse.
Further, one end that A contact and B contact stretch out outside cover body is enclosed with insulating barrier, protects personal safety, improves safety.
Further, for simplifying contact knife structure, this utility model contact knife has bar shaped gap with in the middle part of one end that A contact or grounding contact are connected.
Further, A contact and B contact are oppositely arranged, are turned on by contact knife.
Further, grounding contact is located at B contact side, and B contact and grounding contact are turned on by contact knife.
The beneficial effects of the utility model are: on-load switch of the present utility model is capable of fast arc extinction, between various piece, concordance is good, have simple in construction, easy to operate, insulating properties strong, good reliability, safety advantages of higher, and cost of manufacture is relatively low, and economic worth is higher.

Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model carried out detailed explanation and explanation.
As shown in Figure 1, this utility model provides a kind of on-load switch, and including square airtight cover body 1, this airtight cover body 1 is built by epoxy resin and formed, and in cover body 1, it being filled with the sulfur hexafluoride gas for arc extinguishing, air pressure inside is generally 0.045MPa to 0.06MPa; Draw from cover body 1 interior and build all-in-one-piece A contact 2, B contact 9, grounding contact 7 with cover body 1, drive axle 8 and charge valve 60, " extraction " can be regarded as that these device one end above-mentioned are in the inside of cover body 1, one end is in the outside of cover body 1, cover body 1 is internal is provided with contact knife 3, curved rod 4, drive link 5, contact knife 3, curved rod 4, drive link 5 form drive mechanism of the present utility model, for controlling the switching of this utility model on-load switch.
Specifically, as shown in Figure 1, the hinged B contact 9 in contact knife 3 one end, contact knife 3 can rotate around rotating shaft between the two, contact knife 3 side has been fixed with the fanning strip 30 of interconnection function, certainly, fanning strip 30 can also be integrally machined with contact knife 3 and make, fanning strip 30 hinged curved rod 4 one end, fanning strip 30 is driven by curved rod 4, and then band movable touch knife 3 rotates, the other end hinged drive link 5 one end of curved rod 4, drive link 5 drives curved rod, drive link 5 other end affixed driving axle 8 one end, drive axle 8 vertical with drive link 5, drive link 5 is driven to rotate, drive link 5 drives curved rod 4, curved rod 4 band movable touch knife 3, realize on-load switch to lead to, disconnected, grounding function.Drive axle 8 other end can affixed handle or motor, handle be used for hand control switch opening and closing, relatively simply, motor be used for electric controling switch opening and closing, safety is better; Being inserted with baroceptor 10 on cover body 1, it is internal that baroceptor 10 probe stretches to cover body 1, for detecting the atmospheric pressure value size in cover body 1, it is judged that whether there is the situation of gas leakage or under-inflation, improve safety of the present utility model. This utility model is filled with sulfur hexafluoride gas by charge valve 60 in cover body 1, and in order to realize releasing sulfur hexafluoride gas, this utility model also includes vent valve 61, draws from cover body 1 interior and cover body 1 is built integral. In the connection terminal of the extraction outside cover body, one end that A contact 2 and B contact 9 stretch out outside cover body 1 is enclosed with insulating barrier, it is to avoid staff touches or other dangerous situations by mistake; Inside cover body, for simplifying the structure of contact knife 3, contact knife 3 has bar shaped gap with in the middle part of one end that A contact 2 or grounding contact 7 are connected. In the present embodiment, driving axle 8 through drive link 5 one end central authorities, the fixed connecting end of drive link 5 and driving axle 8 is to the hinged end of drive link 5 with curved rod 4, and the size of drive link 5 is gradually reduced. Observing the duty of each parts in on-load switch in order to convenient, airtight cover body 1 offers at least one observation window, viewing glass sheet seals and is located on cover body 1 observation window. One end that A contact 2 and/or B contact 9 stretch out outside cover body 1 is connected to fuse, and when operating current is bigger, protection on-load switch is not breakdown.
As it is shown in figure 1, on-load switch of the present utility model has three kinds of duties: ground connection, separating brake, combined floodgate. In figure, state is separating brake, and the state represented towards the dotted line of upside is respectively closed a floodgate, and the state represented towards the dotted line in left side is ground connection. In the present embodiment, A contact 2 and B contact 9 are oppositely arranged, being closed a floodgate by contact knife 3 realizes conducting; Grounding contact 7 is located at B contact 9 side, and B contact 9 and grounding contact 7 are by contact knife 3 earth-continuity.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and simple modifications etc. made in this utility model flesh and blood, should be included within protection domain of the present utility model.
