Description
Technical field
The utility model relates to distribution line power equipment technical field.
Background technology
The high voltage isolator generally used in electric power system power distribution circuit at present, owing to being subject to sleet corrosion for a long time out of doors, is very easy to get rusty, and operates very inconvenient when causing its switch sections at separating brake and close a floodgate.The HGW9-12 series outdoor high-voltage isolating switch such as generally used, himself be provided with fixing drag hook and self-locking device, adopt insulation to hook clubs to do, be subject to the corrosion of the natural causes such as sleet for a long time, the easy corrosion of rotation axis of its moving contact and fixed contact and moving contact, its moving contact is easily caused when combined floodgate and sub-switching operation, and point rear conjunction is not in place, the rear inseparable situation of conjunction, brings adverse effect, have a strong impact on power supply safety to operation element.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-tension line spring assist isolating switch, and under the power-assisted effect of spring, make moving contact separating brake rapid, combined floodgate puts in place; Improve operating efficiency, improve the reliability of isolating switch, ensure power supply safety.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of high-tension line spring assist isolating switch, comprise base, post insulator, first binding post, second binding post, moving contact and fixed contact, two post insulators are vertically fixed on base, one end of first binding post and the second binding post is fixed on post insulator top, moving contact is fixed on the first binding post by the movable contact block hinged with moving contact one end, fixed contact is fixed on the second binding post, spring is added between the first binding post and moving contact, one end of spring is fixed on the first binding post, the other end is fixed on moving contact.
Further technical scheme, described spring is extension spring.
Further technical scheme, the quantity of described spring is 2, lays respectively at the both sides of moving contact.
The beneficial effect adopting technique scheme to produce is: between the first moving contact and binding post, be provided with spring, when carrying out sub-switching operation, spring applies tensile force to moving contact, makes separating brake rapid, ensures that moving contact can not close by mistake; When carrying out closing operation, spring applies downward pulling force to moving contact, and combined floodgate is put in place, ensure disconnecting link can not miss separating brake, and avoid due between movable contact block and moving contact due to corrosion close a floodgate and separating brake time bad operation.The utility model improves operating efficiency, greatly improves the reliability of isolating switch, has ensured the fail safe of power supply simultaneously.

In the accompanying drawings: 1, base, 2, post insulator, the 3, first binding post, 4, moving contact, 5, fixed contact, 6, spring, the 7, second binding post, 8, movable contact block, 9, spring strut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, high-tension line spring assist isolating switch, comprises base 1, post insulator 2, binding post, moving contact 4, fixed contact 5 and spring 6.Two post insulators 2 are vertically fixed on base 1.Binding post comprises the first binding post 3 and the second binding post 7, two binding posts are rectangle, and its one end is separately fixed at the top of post insulator 2, and it is respectively equipped with circular hole.Moving contact 4 one end is hinged with movable contact block 8, and movable contact block 8 is vertically fixed on the first binding post 3.Fixed contact 5 is vertically fixed on the second binding post 7, and movable contact block 8 is identical with the height of fixed contact 5.During combined floodgate, by the other end clamping of moving contact 4 on fixed contact 5.On-off mode between moving contact 4 and fixed contact 5 is disconnecting link formula, and namely moving contact 4 rotates relative to movable contact block 8.The blade both sides correspondence position of moving contact 4 is fixed with spring strut 9 respectively, and spring 6 is extension spring, and one end of two extension springs is hooked on the circular hole of binding post, and the other end is hooked on the spring strut 9 of moving contact 4.
When carrying out sub-switching operation, operating personnel operates moving contact 4 and is separated from fixed contact 5, and moving contact 4 rotates relative to movable contact block 8, and spring 6 can apply to moving contact 4 one is pointed to the first binding post 3 active force from spring strut 9.When moving contact 4 turns to certain angle, this active force can produce a component upwards, makes moving contact 4 from quick separating fixed contact 5.Ensure that moving contact 4 can not false switching, and avoid due between movable contact block 8 and moving contact 4 due to corrosion bad operation when separating brake.
When carrying out closing operation, operating personnel operates moving contact 4 and closes to fixed contact 5, moving contact 4 rotates relative to movable contact block 8, when moving contact 4 turns to certain angle, above-mentioned active force can produce a downward component, when making moving contact 4 clamping on fixed contact 5, put in place fast, and close a floodgate firmly.Ensure moving contact 4 can not miss separating brake, and avoid due between movable contact block 8 and moving contact 4 due to corrosion bad operation when closing a floodgate.
