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 compression 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 by flange on ontology, 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 judge input respective direction, phase to the coil in magnetic force operating mechanism 2 according to the instruction received
The electric current of size, magazine 11 is answered to be moved according to the Ampere force that it is subject to, 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
Compression 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, makes three-station isolating grounding switch be maintained 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 is complete at this time discharges, under Ampere force caused by the electric current being passed through is insufficient to allow magazine 11 to continue
It moves to compress lower compression 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 more 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 is opposite to flow direction.
