Embodiment
Elaborate with reference to Fig. 1, Fig. 2 to the present invention.
Embodiment one：
As shown in Figure 1, a kind of electromagnetic drive solid insulation switch cabinet being often grounded, including a hollow insulating boot 1, setting
Static contact 4, grounding contact 8, vacuum bubbles 11 in the insulating boot, for turning on the vacuum bubbles 11 and the grounding contact
8 connection sheet 2 and the moving contact 5 for being adapted to conducting with the static contact 4 and the connection sheet 2 at the same time, the moving contact
5 are located at static contact 4 and the top of connection sheet 2, and the lower section of moving contact 5 is provided with for driving moving contact 5 and static contact 4 and connecting
The electromagnetic actuator device a3 of contact between contact pin 2, the grounding contact 8 are located at the top of connection sheet 2, are gone back in the insulating boot 1
Equipped with electromagnetic actuator device b10, contiguous block 9 is provided between the connection sheet 2 and grounding contact 8, the contiguous block 9 is with connecting
Contact between contact pin 2 and grounding contact 8 is driven by electromagnetic actuator device b10, is filled in electromagnetic actuator device a3 and electromagnetic drive
Put when b10 is not powered on the contiguous block 9 and connection sheet 2 and grounding contact 8 and meanwhile contact, the moving contact 5 is with static contact 4 and even
Contact pin 2 does not contact, and the stroke of the electromagnetic actuator device a3 is more than the stroke of electromagnetic actuator device b10.
In the present embodiment, by being realized in electromagnetic actuator device a3 and electromagnetic actuator device b10 to moving contact 5 and contiguous block
9 driving, so that the switching for controlling combined floodgate, opening a sluice gate, being grounded three kinds of states, specifically, in electromagnetic actuator device a3 and electromagnetism
When driving device b10 is not powered on, since contiguous block 9 and connection sheet 2 and grounding contact 8 contact at the same time, moving contact 5 and static contact 4
Do not contacted with connection sheet 2, whole solid insulation switch is in ground state at this time；Since the stroke of electromagnetic actuator device a3 is more than
The stroke of electromagnetic actuator device b10, when electromagnetic actuator device a3 and electromagnetic actuator device b10 access electric currents are smaller, moving contact 5
Sloping portion distance, contiguous block 9 are moved to the left partial distance, cause contiguous block 9 not contacted with connection sheet 2 and grounding contact 8,
