Description
technical field:
the utility model relates to a kind of high voltage drop-out type fuse cutout.
background technology:
the fusion tube of existing fuse switch exist the moisture absorption, yielding, cut-off that capacity is little, the life-span is short, be not suitable with temperature and sharply change and the shortcoming such as certainly to burst, bring very large potential safety hazard to the line maintenance of operator.
utility model content:
the purpose of this utility model is to provide a kind of high voltage drop-out type fuse cutout.
above-mentioned object is realized by following technical scheme:
a kind of high voltage drop-out type fuse cutout, its composition comprises: ceramic insulator, described ceramic insulator respectively with upper bracket, undersetting connects, described upper bracket and undersetting are separately installed with parallel groove binding post, described upper bracket is connected with fusion tube, described undersetting is connected with described fusion tube, described fusion tube skin is phenolic aldehyde paper tube or expoxy glass stringing, cellulosic expulsion tube is lined with in described fusion tube, in described fusion tube, copper fuse is installed, described fusion tube upper end is provided with membrane pipe cap, described fusion tube two ends are provided with moving contact, described upper bracket and undersetting are separately installed with the fixed contact be connected with moving contact, fixed contact on described undersetting is to provide the silver of dual flow guide to contact under silver, fixed contact on described upper bracket is the upper contact head being provided high contact by stainless steel spring, described fusion tube has water-fast, ultraviolet resistant, described undersetting is gudgeon cover, described ceramic insulator is connected by silver-plated cast copper gudgeon with described gudgeon cover.
described high voltage drop-out type fuse cutout, the middle part of described ceramic insulator is provided with mounting plate, and described mounting plate and support are connected by screw, and described support is connected by long bolt with backboard, described pipe cap electroplating surfaces with tin, described fusion tube is provided with operation ring.
beneficial effect:
1. the utility model is arranged on 10kV distribution line branch line, power failure range can be reduced, because it has an obvious cut-off point of high voltage drop-out type fuse cutout, possesses the function of isolating switch, create a safety work environment to maintenance section circuit and equipment, add the coefficient of safety of maintainer.When being arranged on distribution transformer, can as the main protection of distribution transformer.
2. the operation principle of this high voltage drop-out type fuse cutout is as follows, when normally running, fusion tube forms make position by after fuse tensioning, when system jam, and fuse quick-break during fault current, and form electric arc, expulsion tube is scorching hot by electric arc, decomposites a large amount of gas, makes to form very high pressure in pipe, and forming vertical blowing along pipeline, electric arc is extinguished by elongating rapidly.After fuse failure, bottom moving contact lose tension force and under turn over, locking machinery, release fusion tube, fusion tube falls, formed significantly cut-off position.When needs pulling load, moving contact is pulled open with insulating bar, now main dynamic and static moving contact still contacts, continuation insulating bar pulls contact, and auxiliary contact is also separated, between auxiliary contact, produce electric arc, electric arc is elongated going out in cover slit, arc-extinguish chamber produces gas simultaneously, when current over-zero, by arc extinction.
3. the skin of the utility model fusion tube adopts phenolic aldehyde paper tube or expoxy glass stringing, liner has cellulosic expulsion tube, thus fusion tube have nonhygroscopic, indeformable, cut-off that capacity is large, the advantage such as uvioresistant, life-span are long.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
