Abstract
The utility model relates to a transmission device of an intermediate and high voltage breaker of a piece of power transmission and transformation equipment. The transmission device comprises a transmission frame (2), a transmission shaft (6), an inner crank arm (8) and an outer crank arm (3), etc. wherein, one end of the inner crank arm (8) is articulated with a vertical pull rod of a high voltage breaker and the other end thereof is arranged at one end of the transmission shaft (6); the transmission shaft (6) is arranged on the transmission frame (2) which is fixed to a support plate (1) of the high voltage breaker; the middle part of the outer crank arm (3) is arranged at the other end of the transmission shaft (6); the two ends of the outer crank arm (3) are articulated with a level pull rod of the high voltage breaker. A B-phase operation mechanism when being operated can drive the inner crank arm (8) and the inner crank arm (8) can drive the outer crank arm (3) through the transmission shaft (6) and further the level pull rod is driven to realize a three-phase linkage. The transmission device is characterized by simple structure, high transmission efficiency, more reasonable structure and less cost of the breaker, etc.
Description
Technical field
The utility model is a kind of transmission device that is used for power transmission and transforming equipment mesohigh circuit breaker.
Background technology
At present, the translation seal formula primary cut-out kind of drive adopts power transmission shaft and connecting lever to weld together mostly, be fixed in inboard, crossbeam both sides, and branch, combined floodgate buffer board are welded on the crossbeam, the shortcoming of this drive mechanism is a complex structure, requires operating work big, and transmission efficiency is low, and require crossbeam welding technique level height, in a disguised form increase cost.
Summary of the invention
The purpose of this utility model is that it is simple in structure, transmission efficiency is high for primary cut-out provides a kind of transmission device, and can make the overall structure of circuit breaker more reasonable, has reduced the cost of circuit breaker simultaneously.
In order to achieve the above object, the technical scheme taked of the utility model is: include gear frame, power transmission shaft, interior connecting lever, outer connecting lever etc.One end of interior connecting lever is connected with the vertical pull bar hinge joint of primary cut-out, the other end of interior connecting lever is installed on the end of power transmission shaft and with power transmission shaft and rotates, power transmission shaft by Bearing Installation on gear frame, and can transmission, gear frame is fixed on the supporting plate of primary cut-out, the middle part of outer connecting lever is installed on the other end of power transmission shaft, and can be with the power transmission shaft transmission, the two ends of outer connecting lever link with the girt of primary cut-out and are connected.
Because primary cut-out is by three single-phase combining, when the utility model is used for two ends single-phase, outer connecting lever has only an end to be connected with the girt hinge joint, can save " arm " of the other end like this, just an end of outer connecting lever is connected with power transmission shaft, the hinge joint of the other end and girt is connected.
Operating mechanism when operation B phase, the operating mechanism of B phase passes through its vertical pull bar and drives interior connecting lever, and interior connecting lever drives outer connecting lever by power transmission shaft, the outer connecting lever in the transmission device of outer connecting lever drive girt drive A, C phase, connecting lever in outer connecting lever drives by power transmission shaft realizes that three link.Therefore the utlity model has simple in structure, transmission efficiency is high, and can make the overall structure of circuit breaker more reasonable, has reduced the characteristics such as cost of circuit breaker simultaneously.
Description of drawings
Accompanying drawing is the utility model schematic diagram.
Embodiment
Accompanying drawing is an embodiment of the present utility model, includes gear frame 2, power transmission shaft 6, interior connecting lever 8, outer connecting lever 3 etc.One end of interior connecting lever 8 is connected with the vertical pull bar hinge joint of primary cut-out, the other end of interior connecting lever 8 is installed on the end of power transmission shaft 6 and with power transmission shaft 6 and rotates, power transmission shaft 6 by Bearing Installation on gear frame 2, and can transmission, gear frame 2 is fixed on the supporting plate 1 of primary cut-out, the middle part of outer connecting lever 3 is installed on the other end of power transmission shaft 6, and can be with power transmission shaft 6 transmissions, the two ends of outer connecting lever 3 link with the girt of primary cut-out and are connected.
When the utility model is used for primary cut-out two ends single-phase, because outer connecting lever 3 has only an end to be connected with the girt hinge joint, can save " arm " of the other end like this, an end of just outer connecting lever 3 is connected with power transmission shaft 6, the other end is connected with the girt hinge joint.
Operating mechanism when operation B phase, connecting lever 8 in the operating mechanism of B phase drives by its vertical pull bar, interior connecting lever 8 drives outer connecting lever 3 by power transmission shaft 6, outer connecting lever 3 in the transmission device of outer connecting lever 3 drive girts drive A, C phase, connecting lever 8 in the outer connecting lever 3 of A, C phase drives by power transmission shaft 6 realizes that three link.Therefore the utlity model has simple in structure, transmission efficiency is high, and can make the overall structure of circuit breaker more reasonable, has reduced the characteristics such as cost of circuit breaker simultaneously.
