Description
Technical Field
The utility model relates to a effluent treatment plant, concretely relates to buffer of outdoor circuit breaker.
Background
The circuit breaker can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply circuit, the motor and the like, and automatically cutting off a circuit when faults such as serious overload, short circuit, undervoltage and the like occur, and the function of the circuit breaker is equivalent to the combination of a fuse type switch, an over-under-heat relay and the like. Furthermore, no parts need to be changed after breaking the fault current. In modern society, the power supply can not be separated in the fields of industry, agriculture, transportation, national defense, cultural and educational sanitation, finance, commerce, tourism service, people's life and the like. Distribution of electricity is an extremely important link in the generation, transmission and use of electricity. The distribution system comprises a transformer and various high-low voltage electrical equipment, and the low-voltage circuit breaker is an electrical appliance with a large using amount. The existing breaker buffer structure mostly adopts a rubber cushion for buffering, has large bounce during brake opening and is not easy to adjust.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model adopts the following technical scheme:
the utility model provides a buffer of outdoor circuit breaker, includes the casing, be provided with the separating brake transmission main shaft in the casing, the separating brake transmission main shaft is articulated with the one end of contact spring arm, the other end and the casing of contact spring arm are articulated, be provided with the shift fork on the separating brake transmission main shaft, the articulated turning arm that is provided with and corresponds with the shift fork on the contact spring arm, be provided with the adjustable height's that corresponds with the turning arm oil buffer on the casing.
The welding has the buffer mounting panel on the casing, the vertical installation of oil buffer just is fixed with buffer mounting panel threaded connection, the outer wall of oil buffer is provided with the external screw thread that corresponds with the buffer mounting panel, height that can be fine as required adjustment buffer, and then better regulation buffering intensity.
The inflection point of connecting lever is articulated with contact spring lever, the one end of connecting lever can strike the piston rod upper end of oil buffer, and the connecting lever striking oil buffer's piston rod pushes down the piston, and on the reaction force of oil buffer passed the connecting lever simultaneously, and then passed on the shifting fork, and then played the cushioning effect.
The shell is provided with a rubber gasket corresponding to the contact spring rod, so that a buffering effect is further achieved, and the damage to the contact spring rod is reduced.
The shifting fork is of a pin-type structure with two closed ends corresponding to the opening transmission main shaft, can be better matched with the crank arm for use, and further has a good buffering effect.
Compared with the prior art, the utility model, have following advantage: the utility model discloses simple structure adopts the oil buffer to cushion, has solved the big problem of rubber pad jump degree, and what the buffer adopted is vertical installation moreover, at circuit breaker operating condition, can not have the risk of oil leak, and threaded connection's oil buffer can also adjust the intensity of buffering through the height of adjusting the oil buffer, and the result of use is better.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is an installation diagram of the oil damper of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention.
Example (b): as shown in fig. 1-2, this embodiment provides a buffer of outdoor circuit breaker, including casing 1, be provided with separating brake transmission main shaft 2 in the casing 1, separating brake transmission main shaft 2 is articulated with contact spring lever 3's one end, contact spring lever 3's the other end is articulated with casing 1, be provided with shift fork 4 on separating brake transmission main shaft 2, articulated being provided with the turning arm 5 that corresponds with shift fork 4 on the contact spring lever 3, be provided with the adjustable height's that corresponds with turning arm 5 buffer 6 on the casing 1. The welding has buffer mounting panel 101 on casing 1, the vertical installation of oil buffer 6 just is fixed with buffer mounting panel 101 threaded connection, the outer wall of oil buffer 6 is provided with the external screw thread that corresponds with buffer mounting panel 101, the height of the regulation buffer that can be fine as required, and then better regulation buffering intensity. The inflection point of the crank arm 5 is hinged with the contact spring rod 3, one end of the crank arm 5 can strike the upper end of a piston rod of the oil buffer 6, the crank arm strikes the piston rod of the oil buffer, the piston is pressed downwards, and meanwhile, the reaction force of the oil buffer is transmitted to the crank arm, so that the crank arm is transmitted to the shifting fork, and the buffering effect is achieved. The shell 1 is provided with a rubber gasket 7 corresponding to the contact spring rod 3, so that a buffering effect is further achieved, and the damage to the contact spring rod 3 is reduced. The shifting fork 4 is a pin-shaped structure with two closed ends corresponding to the opening transmission main shaft 2, can be better matched with a crank arm for use, and further has a good buffering effect, and the oil buffer 6 selects the existing model products according to actual needs.
When concrete you use, the separating brake transmission main shaft moves right, drive the shift fork right, stir the connecting lever motion afterwards, striking oil buffer, play the effect of separating brake buffering, this embodiment simple structure adopts oil buffer to cushion, the problem that the rubber pad degree of jumping is big has been solved, what the buffer adopted in addition is vertical installation, at circuit breaker operating condition, there is not the risk of oil leak, threaded connection's oil buffer can also adjust the intensity of buffering through the height of adjusting oil buffer, the result of use is better.
The present invention is illustrated by way of example and not by way of limitation. It will be apparent to those skilled in the art that other variations and modifications of the present invention can be made in light of the above teachings, and it is not necessary or necessary to exhaustively enumerate all embodiments herein, and it is intended that all such obvious variations and modifications are within the scope of the present invention.
