Description
Technical field
The utility model relates to the indoor AC high voltage vacuum breaker in a kind of electrical power distribution system, and is special relevant with the operating mechanism of 10kV and following electric pressure high-pressure vacuum breaker.
Background technology
The traditional indoor AC high voltage vacuum breaker operating mechanism of electrical power distribution system is a mechanical driving mechanism, mainly partly is made up of connecting rod, snap close and energy supply system etc.This mechanical driving mechanism link is many, the cumulative movement tolerance is big, response slowly, the response time is generally wanted a few tens of milliseconds, and poor controllability, efficient are low.In addition, dispersiveness operate time of these operating mechanisms is also bigger, and for AC controling signal even greater than 10ms, even adopt dc operation, the dispersiveness of operate time is also at Millisecond.Therefore, operating mechanism can only be realized the action request of circuit breaker, but course of action is uncontrollable, can not realize real-time regulated and control to operating process.So the moving contact kinetic characteristic of the primary cut-out under the traditional control method is difficult to reach the requirement of 10kV and following electric pressure handcart-type indoor high-voltage vacuum circuit breaker.
In recent years, the further investigation of permanent magnet mechanism and exploitation, and obtained the theory and practice achievement; Make its above problem be able to perfect solution.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is little, makes the indoor high-voltage vacuum circuit breaker operating mechanism that circuit breaker is reliable, mechanical endurance is long.
The technical solution of the utility model is, a kind of indoor high-voltage vacuum circuit breaker operating mechanism, comprise insulated tension pole and main shaft, it is characterized in that, also include linear electric motors and servo-control system, the moving contact of circuit breaker links to each other with a connecting lever of main shaft by insulated tension pole, and another connecting lever of main shaft links to each other with the secondary iron core of linear electric motors, and linear electric motors are controlled by servo-control system.
The utility model indoor high-voltage vacuum circuit breaker operating mechanism is the linear servo-actuator operating mechanism, linear servo-actuator can frequent starting, stop, brake, reverse, have good capability of fast response, Dead Time is little, mechanical friction is little, magnetic property and electric property equilibrium, particularly linear servo-actuator has the control performance of high reliability, high stability, high-speed, high accuracy and high quick little feeding, is more suitable for the SERVO CONTROL of high speed starting and stopping and position.This operating mechanism has been broken through the principle and the thinking of operating mechanism in the past, straight-line mechanism has replaced a whole set of complicated mechanical driving mechanism of former primary cut-out, only goes directly to drive the operating axis lead agency motion of circuit breaker with an electronically controlled linear servo-actuator.
The utility model indoor high-voltage vacuum circuit breaker operating mechanism is simple in structure, and volume is little, can realize the Based Intelligent Control of cut-offfing and closing the process of closing of circuit breaker, has improved circuit breaker reliability of operation and mechanical endurance.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model indoor high-voltage vacuum circuit breaker operating mechanism.
Fig. 2 is the structural representation of the utility model indoor high-voltage vacuum circuit breaker operating mechanism linear electric motors embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, permanent magnet 2, armature coil 3, elementary iron core 4, secondary iron core 5, nonmagnetic substance 6, insulated tension pole 7, linear electric motors 8, main shaft 9, servo-control system
Linear electric motors shown in Figure 2 mainly are made up of permanent magnet 1, armature coil 2, elementary iron core 3, secondary iron core 4 and nonmagnetic substance 5.Elementary iron core 3 has silicon steel plate stacking to form, and be furnished with winding in the groove, embedded opposite polarity permanent magnet 1 on the secondary iron core 4 successively, permanent magnet 1 constitutes the magnetic pole of motor, isolated between the adjacent two-stage with non-magnet material 5, armature coil 2 is arranged apart from the mode of wave winding by direct current machine is whole in groove, armature coil 2 feeds electric current, electric current is subjected to Ampere force in the magnetic field that permanent magnet 1 produces effect promotes secondary iron core 4 motions, armature coil 2 under the different magnetic poles feeds the opposite electric current of directions, makes the thrust maximum that synchronization produced.Can control the size of motor power output by the size that changes electric current in the armature coil 2.Sense of current is moved motor in the opposite direction in the armature coil 2 by changing.Because circuit breaker is short-term operation, each operating time is very short, and motor can the high overload operation, so design of electrical motor is very little, reduces to operate the volume of season greatly, and its control is also flexible.
The utility model indoor high-voltage vacuum circuit breaker operating mechanism as shown in Figure 1, comprise insulated tension pole 6 and main shaft 8, also include linear electric motors 7 and servo-control system 9, the moving contact of circuit breaker links to each other with a connecting lever of main shaft 8 by insulated tension pole 6, another connecting lever of main shaft 8 links to each other with the secondary iron core 4 of linear electric motors 7, and linear electric motors 7 are by servo-control system 9 controls.
The main shaft 8 of circuit breaker drives the moving contact of breaker action, realizes the combined floodgate and the separating brake of circuit breaker with this.This linear servo-actuator operating mechanism volume is little, in light weight, has only a moving component, simple in structure, reliability height, efficient height, power consumption is low, response speed is fast, can guarantee that the circuit breaker that provides basic drives function, more can realize the intellectuality of breaker operator, for circuit breaker provides more advanced application platform new technology.
