Problems solved by technology
[0003] However, when the existing pressure induction tube is affected by factors such as the external interference current received by the pipeline, the insulation and grounding of the pipeline, etc., the discharge of the pressure induction tube will be caused, sparks will be generated, and the discharge and ablation of the pressure induction tube will occur, thereby affecting the safety of the pipeline. Therefore, there is an urgent need for an experimental device for monitoring the discharge ablation of the impulse tube, which is used for the relevant experimental research on the mechanism and influencing factors of the discharge ablation of the impulse tube, in order to obtain the impact of the discharge ablation of the impulse tube. The reduction measures provide theoretical basis and experimental data, and then eliminate safety hazards according to the reduction measures to ensure the safe operation of the pipeline

The embodiment of the invention discloses an experiment apparatus simulating pressure-leading pipe discharge ablation. The experiment apparatus comprises an experiment system assembly, a test system assembly and a power supply system assembly. The experiment system assembly comprises an experiment device body, a first pressure leading pipe, a second pressure leading pipe, a first fixing device, a second fixing device, a first insulating support, a second insulation support, a guide rail, a first metal plate and a second metal plate. The test system assembly is used for measuring discharge ablation parameters of the first pressure leading pipe and second leading pipe under a preset gap. The power supply system assembly is used for supplying the experiment system assembly and the test system assembly with power. According to the experiment apparatus provided by the embodiment of the invention, related researches of a first pressure leading pipe discharge ablation effect mechanism and influence factors so as to provide theoretical basis and experiment data for decreasing measures for pressure-leading pipe discharge ablation, thereby ensuring safe operation of pipelines through elimination of safety hidden troubles by means of the decreasing measures.
Description
technical field [0001] The invention relates to the technical field of pressure induction discharge, in particular to an experimental device for simulating discharge ablation of a pressure induction tube. Background technique [0002] The gas-liquid linkage valve, valve head and pressure induction pipe are used in the existing oil and gas transmission pipeline. An insulating ferrule is installed on the valve body to isolate the control part from the valve body. [0003] However, when the existing pressure induction tube is affected by factors such as the external interference current received by the pipeline, the insulation and grounding of the pipeline, etc., the discharge of the pressure induction tube will be caused, sparks will be generated, and the discharge and ablation of the pressure induction tube will occur, thereby affecting the safety of the pipeline. Therefore, there is an urgent need for an experimental device for monitoring the discharge ablation of the impul...
