Switch further include with magnetic force operating mechanism 2 by cable 3 be connected control magnetic force operating mechanism act mechanics controller 5 and to
Mechanics controller assigns separating brake, isolation is closed a floodgate and the host controller 6 of contact of earth order, mechanics controller 5 and upper control
Device 6 is respectively positioned in mechanism case 4.
As shown in Fig. 2, magnetic force operating mechanism 2 includes institutional framework 7, it has been sequentially arranged in left-right direction in institutional framework 7
Left permanent magnet 9, intermediate permanent magnet 8 and right permanent magnet 10, wherein form the first magnetic between left permanent magnet 9 and intermediate permanent magnet 8
Field gap, forms the second gapped magnetic field, between the first gapped magnetic field and the second magnetic field between intermediate permanent magnet 8 and right permanent magnet 10
The parallel magnetic field of gap it is contrary.It is set with magazine 11 on intermediate permanent magnet 8, is wound with electromagnetism on magazine 11
Coil, in the present embodiment, magazine 11 is square configuration, and the electromagnetic coil being wrapped on magazine includes being located at the first magnetic
Coil first part in gap and the coil second part in the second gapped magnetic field, wherein coil first part and
The extending direction of coil second part corresponds to the magnetic direction perpendicular to the first gapped magnetic field and the second gapped magnetic field.Work as coil
After energization, magazine 11 can be realized movement upward or downward.
It is set on magazine 11 there are four the connecting rod 15 vertically extended, the upper end of connecting rod 15 is by institutional framework 7
Middle guiding is pierced by, and is equipped with mechanism output rod 16 in the upper end of connecting rod 15, mechanism output rod 16 is rack structure, passes through rack-and-pinion
Transmission mechanism drives the transmission shaft of ontology to be rotated, and then drives the moved end movement completion isolation of ontology to close a floodgate, separating brake
It is operated with contact of earth.
Compression spring 12 is housed in the outer cover of connecting rod 15, compression spring 12 is flexibly supported in magazine 11 and institutional framework 7
Between.It is equipped with pressure spring positioning column 14 in the lower end of magazine 11, lower pressure spring 13 is set on pressure spring positioning column 14, in mechanism frame
Frame 7 is equipped with pressure spring positioning column corresponding with the pressure spring positioning column of magazine, and one end of lower pressure spring 13 can be set in pressure spring
On positioning column, the lower resilient support of pressure spring 13 is between 11 lower end of magazine and institutional framework 7.
Magazine 11 can be suspended by the two-way function of compression spring 12 and lower pressure spring 13 and be maintained at fixed position,
Magazine can be made to be maintained at intermediate position by the force value of change pressure spring.When magazine 11 is in an intermediate position, three
Station isolation grounding switch is in the position of separating brake, and being passed through electric current to coil can make magazine move up three stations of realization
The isolation closing operation of isolation earthing switch, being passed through reverse current to coil can make magazine move down three stations of realization
The contact of earth of isolation earthing switch operates.In the present invention, by between the top and bottom and institutional framework of magazine
Resilient support has pressure spring, and making the tool of magazine 11, there are three exact operating positions, convenient for the control to 11 stroke of magazine
System.
In the present invention, magnetic force operating mechanism is fixed on ontology by flange, and magnetic force operating mechanism passes through cable and mechanism
Controller is connected, and host controller and mechanics controller are placed in jointly in mechanism case 4.
The course of work of three-station isolating grounding switch is as follows: under original state, magazine 11 is in an intermediate position, and three
Station isolation grounding switch is in the position of separating brake.When isolation is closed a floodgate, host controller 6 assigns isolation reclosing command to mechanism control
Device 5 processed, mechanics controller 5 should input respective direction, phase to the coil in magnetic force operating mechanism 2 according to the instruction judgement received
The electric current of size is answered, magazine 11 is moved according to the Ampere force that it is subject to, and the direction of motion is consistent with Impact direction, stress
Direction can judge that move distance depends on size of current, and the Ampere force of the bigger generation of electric current is bigger, in compression according to left hand rule
Pressure spring 12, when magazine 11 is moved upwards up to limes superiors position, three-station isolating grounding switch is in isolation "on" position, line
Circle, which remains powered on state, is maintained at three-station isolating grounding switch under isolation "on" position.
When separating brake, host controller is assigned separating brake and is instructed to mechanics controller, and mechanics controller is sentenced according to the instruction received
It is disconnected to input respective direction, electric current of corresponding size to the coil in magnetic force operating mechanism, current direction when separating brake with every
Current direction when clutch lock is opposite.Magazine 11 is moved downward to flat under the action of compression spring 12 and the Ampere force being subject to
Weighing apparatus position, compression spring 12 discharges completely at this time, under Ampere force caused by the electric current being passed through is insufficient to allow magazine 11 to continue
It moves to compress lower pressure spring 13 and stretch compression spring 12, magazine 11 is maintained at equilbrium position.
When contact of earth, same direction current when be passed through into coil greater than separating brake makes magazine 11 in the work of Ampere force
Spring 13, which is pushed, with lower compression is grounded closing operation, when magazine 11 is moved down into limit inferior position, the isolation of three stations
Earthing switch is in contact of earth state, and coil, which remains powered on state, makes three-station isolating grounding switch be maintained at contact of earth shape
Under state.State when becoming separating brake from contact of earth and the above-mentioned state electricity that is similar, but being passed through be isolated and closed a floodgate when becoming separating brake
It flows contrary.
Host controller involved in the present invention includes man-machine interactive system, integral type video-stream processor, host controller
With mechanics controller by fiber optic communication, host controller can assign instruction to mechanics controller, also can be read, receiving mechanism control
The status information and feedback information of device processed complete the monitoring to magnetic force operating mechanism real-time status, and these data are passed through
IEC61850 communications protocol is uploaded to network system backstage or is stored in for reference in host controller.
In the present embodiment, electromagnetic coil is in interposition when magazine is in an intermediate position, and moved end is in separating brake at this time
Position；Magazine is moved upward to electromagnetic coil when moved end is in isolation closing position and is in the first limit position；Magazine is downward
It is moved to electromagnetic coil when moved end is in contact of earth position and is in the second limit position.
The specific embodiment two of three-station isolating grounding switch of the present invention, with above-described embodiment the difference is that, electricity
The corresponding relationship of each position of each position and moved end of magnetic coil is different, and the isolation as the interposition of electromagnetic coil corresponds to moved end is closed
Lock position, the first limit position of electromagnetic coil correspond to the sub-gate position of moved end, and the second limit position of electromagnetic coil corresponds to the ground connection of moved end
Closing position.
