Summary: | Taking an intrinsic safety circuit of passive rescue telephone as an example, the paper analyzed test process of safe spark test of the circuit under different electrical principle equivalent diagrams of intrinsic safety test, and indicated that spark apparatus should be connected into test points which maybe produce the highest spark energy in the tested circuit, which can ensure intrinsic safety circuit has enough safety factor after passing spark test. |
