The stress detection device is arranged on the periphery of the long oil and gas transmission pipeline and is in an electrified state for a long time.
When the oil and gas pipeline leaks once, inflammable and explosive objects in the pipeline can be distributed in the space around the leakage part, so that the environment where the stress detection device is located is changed into inflammable and explosive environment, namely the environment which needs explosion prevention, the existing stress detection circuit is used for a long time under the condition that voltage fluctuation is large, the voltage can be higher than or lower than the rated voltage of components, the components are burnt, the surrounding environment is easy to ignite or detonate, and potential safety hazards exist.
