Abstract
The utility model discloses a breaker oil buffering device. The breaker oil buffering device comprises a piston and an oil buffering cap. The breaker oil buffering device is characterized in that: a through hole penetrates an upper end of the piston; the oil buffer cap is provided with a mounting hole matched with the through hole; and the mounting hole is fixedly connected with the through hole through a connection component. The breaker oil buffering device is advantageous in simple structure, novelty, rationality and convenient operation, capability of reliably solving the problem of oil leakage of an oil buffer as well as the problem in connection installation of the oil buffer cap and the piston, ensured switch-off characteristic of a circuit breaker, and greatly improved performance and service life of a product.
Description
Technical field
The utility model relates to high-tension distribution equipment, is specifically related to a kind of oil buffer device of breaker.
Background technology
The oil bumper cap is connected with elastic spring with piston in the circuit breaker at present, and the piston junction is provided with draw-in groove, and during the oil bumper assembling, when piston passed end cap, the draw-in groove on the piston easily cut up the sealing ring in the end cap, can not reliably prevent leakage of oil during use; And oil bumper cap and piston junction elastic spring be when installing, and when needing elastic spring shunk with specific purpose tool it pushed in the shrinkage pool of cap, is not easy to control, and affects the breaker open operation characteristic.
The utility model content
The technical problems to be solved in the utility model provides a kind of oil buffer device of breaker, simple in structure, thinking is new reasonable, easy to operate, solved the problem of oil bumper oil leakage phenomenon and oil bumper cap and piston connection reliably, guarantee the opening characteristic of circuit breaker, improved greatly properties of product and useful life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of oil buffer device of breaker comprises piston and oil bumper cap, runs through being provided with through hole on the described piston, and described oil bumper cap is provided with the installing hole that is complementary with through hole, and described installing hole is fixedly connected with by link with through hole.
Preferably, described link is spring pivot.
Preferably, described through hole is circular hole.
Preferably, described piston passes end cap and the oil bumper cap interconnects.
Preferably, the junction of described piston and end cap is provided with sealing ring.
By technique scheme, the beneficial effects of the utility model are:
By the mode that draw-in groove on the piston is removed, destroy the phenomenon of sealing ring in the time of can solving assembling fully; Change piston into spring pivot with the connected mode of oil bumper cap and be connected, be more convenient for producing and install.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Described with reference to Fig. 1-Fig. 3, a kind of oil buffer device of breaker comprises piston 1 and oil bumper cap 2, and described piston 1 upper end is run through and is provided with through hole 3, described oil bumper cap 2 is provided with the installing hole 4 that is complementary with through hole 3, and described installing hole 4 and through hole 3 are fixedly connected with by link.
Preferably, described link is spring pivot 6.
Preferably, described through hole 3 is circular hole.
Preferably, described piston 1 passes end cap 7 and interconnects with oil bumper cap 2.
Preferably, described piston 1 is provided with sealing ring 5 with the junction of end cap 7.
Operation principle of the present utility model:
The utility model efficient solution has guaranteed the opening characteristic of circuit breaker except the problem of oil bumper cap 2 with piston 1 connection, has improved greatly properties of product and useful life.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
