Description
Technical field
The present invention relates to a kind of power equipment, the automatic three-phase synchronous drop-out fuse of one that especially outdoor transformer is used.
Background technology
Domestic existing outdoor type transformer is all single-phase operation with fuse, hanging upper contact head annular distance with another gram of rod of insulation is swinging indefinite in the situation that, lower contact ears are hung into undersetting, and three-phase operates respectively, separately completes like this, not only difficult, time-consuming, effort but also dangerous.
With high technology content, expensive technological means or equipment, all unrealistic with fuse for the outdoor type transformer that amount is large, wide.
The patent No. of being invented by the applicant is that 200620098873.1 " three-phase linkage drop-out fuse " and second generation product patent number are 200720083838.7 " three-phase linkage drop-out fuse ", invent plug-type three-phase linkage drop-out fuse that energy three-phase ganged closes a floodgate simultaneously, improve operating efficiency, reduce labor intensity, save time, convenient, safety, extensively promote the use on outdoor type transformer.But close a floodgate because pushing pressure type on being, fusible link contact is reliable not, easy burn-out, be not durable.Concentrate on studies and invented " semi-automatic synchronized drop-out fuse " that the patent No. is 201020174695.2 through me, on changing, pushing pressure type closes a floodgate as above pushing away the semi-automatic synchronized drop-out fuse of automatic closing, make structure simpler, work faster, fusible link contact firmly, more durable in use.But in use find that the patent No. is 201020174695.2 " semi-automatic synchronized drop-out fuse ", in the time that fusible link blows, the fusible link at its two has also just all been scrapped, and saves not, waste is large; Its fusible link is to buy in addition simultaneously, and in the time that fusible link blows, its user is difficult to again buy fusible link for the moment, affects normal electricity consumption; On push away automatic closing structure because of rod member many, feed motion not easily, quick.The applicant is for the problem of above existence, 201110342804.6 " a kind of Semi-automatic three-phase synchronous drop-out fuses " are invented again, improve in this invention dynamic and static structure of contact terminal, improved useful life of fusible link, made the contact of fusible link only have original 1/4; Make on fuse with fusible link for subsequent use; The structure that makes to push away automatic closing is simpler, compact, closes a floodgate more easily, quick.
Through 8 years concentrate on studies and 4 amendments, 201110342804.6 " a kind of Semi-automatic three-phase synchronous drop-out fuses " that use now, it realizes one, and fusing, three-phase synchronous fall mutually, the function of once above push away, three-phase synchronous closing a floodgate is extremely successful, but overall structure is also disliked inadequate optimization, for further succinct, optimization overall structure, make upper and lower dynamic and static contact more stable, on push away feed motion more easily, quick, stable, the applicant has done again material alteration, has made " a kind of three-phase synchronous drop-out fuse automatically ".
According to retrieval, domestic not yet have a patent application identical with the present invention.
Summary of the invention
For described above, the invention provides the second generation upgrading products of 201110342804.6 " a kind of Semi-automatic three-phase synchronous drop-out fuses "---" a kind of three-phase synchronous drop-out fuse automatically ".The present invention's " a kind of three-phase synchronous drop-out fuse automatically " has made significant improvement, has made upper and lower dynamic and static contact more stable upper and lower dynamic and static structure of contact terminal, and more optimized structure, makes fusible link durable in use; In raising, push away the integrated horizontal of three-phase automatic closing structure, the action that three-phase synchronous is closed a floodgate is more stable, light, quick; Make overall structure more succinct, optimize, realize one mutually fusing, three-phase synchronous fall, the automatic three-phase synchronous drop-out fuse of one once above push away, three-phase synchronous closing a floodgate.
