When the vehicle is determined to be started continuously under special conditions after the vehicle is powered off, the relay can be controlled to be closed through the anti-explosion manual reset switch 11, so that the vehicle is powered on.
The main potential ignition sources of the power cut-off instrument are a DC/DC power supply 2, a first intrinsic safety direct-current power supply 3, a second intrinsic safety direct-current power supply 4, an intrinsic safety type machine core 5, a relay driving board 6, a first relay 7, a second relay 8, a third relay 9, a fourth relay 10 and a binding post 12.

DC/DC power supply 2, first ann DC power supply 3, second ann DC power supply 4, relay drive plate 6, first relay 7, second relay 8, third relay 9, parts such as fourth relay 10 possess the explosion-proof protection of encapsulation type, prevented the danger of burning on fire and explosion from the source, even under the condition that the protection of encapsulation became invalid under extreme condition, because the guard action of flame proof shell 1, can not cause extreme harm to external environment yet. The arrangement of the binding post 12 meets the safety-increasing type explosion-proof protection standard, and even if the safety-increasing type explosion-proof protection measures fail under extreme conditions, the explosion-proof shell 1 does not cause extreme harm to the external environment due to the protection effect.
