Abstract
The utility model discloses a vacuum circuit breaker with permanent magnetic actuator, which is characterized in that: a universal joint (12) is fixed at the lower end of a mechanical output rod (13); the lower end of the universal joint (12) is connected with a closing regulating lever (11) through a pin shaft; the switching of the breaker can be finished through the cooperation between the closing regulating lever (11) and the big shaft (7) of the breaker. The breaker has the advantages of avoiding transverse force of the mechanical output rod, prolonging the service life of the mechanism and improving the efficiency of the mechanism during closing and separating brake process.
Description
Technical field
The utility model relates to a kind of electric power vacuum circuit-breaker, and is special relevant with a kind of permanent magnetic actuator vacuum circuit breaker.
Background technology
Its operating mechanism of conventional high-tension vacuum circuit-breaker mainly adopts spring mechanism, and parts are many, complex structure, thereby the source of trouble is many, and long-term frequent operation, the failure rate height, dependability is poor, and maintenance workload is big.Mainly few, the reliable in action of motion parts, combined floodgate characteristic cooperate than advantage such as traditional operating mechanism is better and receive much attention the permanent magnetic actuator vacuum circuit breaker of Chu Xianing with vacuum circuit-breaker with it in recent years.But, present permanent magnetic actuator vacuum circuit breaker only leans against in the transmission of power opens slotted hole on the connecting lever, in the divide-shut brake process, the connecting lever hole directly contacts with the pin of mechanism's take-off lever, frictional force is big, efficient is not high, and causes the damage of mechanism easily, has brought more problem for simultaneously the control section of permanent magnet mechanism yet.
The utility model content
The purpose of this utility model is to provide a kind of mechanism take-off lever laterally not stress the permanent magnetic actuator vacuum circuit breaker that efficient is higher.
The technical solution adopted in the utility model is: the mechanism take-off lever lower end at the vacuum circuit-breaker permanent magnet mechanism is fixed with a universal joint, the lower end of universal joint is connected on the combined floodgate connecting lever by bearing pin, and the combined floodgate connecting lever cooperates the on/off switch operation of finishing circuit breaker with the macro-axis of circuit breaker.
The permanent magnetic actuator vacuum circuit breaker that the utility model provides, mechanism's take-off lever, universal joint and combined floodgate connecting lever are formed mechanism's output.In the divide-shut brake process, can realize not allowing mechanism's take-off lever lateral stressed by universal joint, promptly the center of the center in connecting lever hole and mechanism's take-off lever is not on same straight line, be not easy to cause the damage of mechanism, the reliability height of entire mechanism, failure rate is low, can frequent operation.
Description of drawings
Fig. 1 is the structural representation of existing permanent magnetic actuator vacuum circuit breaker;
Fig. 2 is the structural representation of an embodiment of the utility model permanent magnetic actuator vacuum circuit breaker when closing position;
Fig. 3 is the structural representation when the separating brake position embodiment illustrated in fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, the combined floodgate connecting lever of insulating sleeve 2, insulated tension pole 3, big connecting lever 4, bearing pin 5, link plate 6, tripping spring 7, macro-axis 8, connecting lever 9, connecting plate 10, framework 11, combined floodgate connecting lever 12, universal joint 13, mechanism's take-off lever 14, permanent magnet mechanism 15, vacuum interrupter 16, belt length circular hole
As Fig. 2, shown in Figure 3, the utility model permanent magnetic actuator vacuum circuit breaker, vacuum interrupter 15 are fixed on the insulating sleeve 1, are fixed in the bottom of framework 10 by screw thread.Insulated tension pole 2 is positioned at the lower end of vacuum interrupter 15 and uses nut fastening.The left end of big connecting lever 3 is connected with the lower end of insulated tension pole 2, and big connecting lever 3 bodies place in the framework 10, and its middle part is provided with a circular hole.Bearing pin 4 places this circular hole and hinged with framework 10, and big connecting lever 3 can rotate around bearing pin 4.One end of connecting plate 9 is hinged with the right-hand member of big connecting lever 3, and the connecting lever 8 on the other end of connecting plate 9 and the macro-axis 7 is hinged.Be connected with a universal joint 12 in mechanism's take-off lever 13 lower ends by screwed hole, the lower end of universal joint 12 is connected on the combined floodgate connecting lever 11 by bearing pin, and combined floodgate connecting lever 11 cooperates the on/off switch operation of finishing circuit breaker with the macro-axis 7 of circuit breaker.
When circuit breaker need close a floodgate, the coil of permanent magnet mechanism 14 is charged, driving mechanism take-off lever 13 moves downward, and drives universal joint 12, combined floodgate connecting lever 11, and the rotation of combined floodgate connecting lever 11 can be ordered about macro-axis 7 and clockwise rotate, the connecting lever 8 that the rotation of macro-axis 7 simultaneously can drive each phase rotates, connecting lever 8 is pushed down connecting plate 9 downwards, forces big connecting lever 3 right-hand members to move downward, and spring 6 is stretched, big connecting lever 3 left ends move upward, and make the dynamic/static contact closure of vacuum interrupter 15 finish the operation of combined floodgate.In the combined floodgate complete process,, can not occur the lateral stressed phenomenon of mechanism's take-off lever again, thereby prolong the useful life of mechanism, improve the efficient of mechanism owing to used universal joint.
