Description
Technical field
The utility model relates to the transmission mechanism in the circuit breaker, is the transmission mechanism between operating mechanism and arc control device.
Background technology
Traditional circuit breaker (vacuum, SF6, wet goods circuit breaker) is the public macro-axis of three-phase, operating mechanism drives macro-axis and rotates, macro-axis drives three pull bar motions by the rotation of weldering three connecting levers (or by spline and equipped connecting lever thereof) thereon, three pull bars drive the moving contact motion of arc control device by the connecting lever that connects separately, and finish breaking-closing operating.Therefore, the transmission mechanism between breaker operation mechanism and the arc control device is to remove actuating three-phase arc control device respectively again by public macro-axis.Because the resistance of motion of three-phase arc control device is big, and act on respectively on the different cross section of macro-axis, macro-axis bends and torsional deflection during combined floodgate, influence the kinetic characteristic of three-phase arc control device moving contacts, caused characterisitic parameters such as divide-shut brake speed, branch wire time, divide-shut brake same period, stroke, the excess of stroke, spring, loop resistance inconsistent and unstable; When adjusting each characterisitic parameter, interference is arranged between the three-phase, be unfavorable for realizing the optimization of characterisitic parameter.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of operating mechanism of circuit breaker and the transmission mechanism between arc control device, cancels public macro-axis, makes the reliable stable of circuit breaker.
The operating mechanism of circuit breaker of the present utility model and the transmission mechanism between arc control device, comprise driving member, driving member one end is connected with operating mechanism, the other end connects with the moving contact of three-phase arc control device, it is characterized in that described driving member comprises axle sleeve, axle sleeve is connected with operating mechanism, has three output shafts on the axle sleeve, connects with the moving contact of three-phase arc control device by three output shafts.
Transmission mechanism of the present utility model has been cancelled original public macro-axis, and the effect by a driving member equivalence macro-axis has overcome the drawback that original public macro-axis brought.Operating mechanism direct manipulation driving member can be direct between the moving contact of driving member and three-phase arc control device or be connected by lever or by connecting plate.Have axis hole on the described axle sleeve, be connected with operating mechanism by the axis hole driving member.
Because the power that produces during breaker closing is very big, easily all parts are produced impulsive force, in order to alleviate this impulsive force, the utility model is taked buffering method: insert vertical shaft in the axle sleeve, vertical shaft and shaft room have slotted hole, add the fixed axis pin in the slotted hole, are added with buffer in the vertical shaft.Slotted hole mode purpose of connecting is can act on the buffer when making axle sleeve along the vertical shaft back and forth movement, reduces strong impact.Described buffer comprises lubricating cup, and the lubricating cup bottom is added with spring, is added with piston in the lubricating cup, and piston is fixedlyed connected with an end of vertical shaft, leaves the gap between lubricating cup and vertical shaft.
Can be connected by connecting plate between the moving contact of the above driving member and three-phase arc control device, promptly three output shafts on the axle sleeve connect connecting plate respectively, and connecting plate is connected with the moving contact of arc control device; Can connect by the lever mode, promptly connecting plate is connected with the moving contact of arc control device by connecting lever again.
The arrangement that should misplace of three output shafts on the driving member, three-phase arc control device or run on one plane or be distributed on the radius circular arc identical or inequality are installed for convenience.
Operating mechanism is still by original mode, promptly can be in the lower end of arc control device, and also can be at the front end of arc control device.
Operating mechanism of the present utility model can be a multiple mode of the prior art, as permanent magnet mechanism, electromagnetic mechanism, spring mechanism, hydraulic mechanism etc.
Advantage of the present utility model:
Transmission mechanism of the present utility model has changed the mode that original three-phase active force is scattered in diverse location, has cancelled public macro-axis, has improved circuit breaker reliability of operation and stability.Characterisitic parameter height one such as divide-shut brake speed, branch wire time, divide-shut brake same period, stroke, the excess of stroke, spring, loop resistance are made peace highly stable; Contact pressure and three-phase arc control device bear that to cut-off the load equal altitudes that parts bore used in arc energy and the three-phase consistent.Be convenient to optimize and debugging: when adjusting each characterisitic parameter, each is independent of each other mutually, does not disturb mutually, helps realizing the optimization of characterisitic parameter.Below with the comparative descriptions of partial parameters superiority of the present utility model:
Press standard-required, the three-phase excess of stroke of circuit breaker is 4 ± 1 millimeters, and from normal performance circuit breaker turning circuit and the function and the circuit breaker electrical endurance that cut-off circuit, the three-phase excess of stroke preferably all is same value.For example all be 4 millimeters or 4.1 millimeters etc.But because the flexural deformation of the public macro-axis of prior art in making process and the influence of torsional deflection can't reach the requirement of this same value at all.It is many in 0.3 millimeter that original circuit breaker A, B, C three-phase excess of stroke value differ, and reaches 1 millimeter when maximum, and the excess of stroke of novel breaker can realize that A, B, C three-phase are in full accord, is same value simultaneously.
Table 1: the excess of stroke is (unit is a millimeter) relatively
Table 2: stroke ratio is (unit is a millimeter)
