Description

technical field [0001] The invention relates to a test bench and a test method, in particular to a test bench and a test method for a high-voltage sheath of an ignition system of an automobile engine. Background technique [0002] The high-voltage sheath of the ignition system of the automobile engine is a key rubber component of the ignition system on the automobile engine, which can protect the high voltage generated instantaneously when the engine is ignited. The ignition system is to change the low-voltage electricity of the power supply into high-voltage electricity, and then send electric sparks into the cylinders to ignite the combustible mixture in a timely manner according to the working sequence of each cylinder of the engine. When the high-pressure sheath works in the cylinder, it needs to withstand harsh working conditions such as high temperature, high pressure, and oil and gas erosion. According to the relevant requirements of the standard GB / T1695-2005 and AS...

AI Technical Summary

Problems solved by technology

According to the relevant requirements of the standard GB / T1695-2005 and ASTMD149-09 (2013), the voltage breakdown strength of the high-voltage sheath of the vehicle engine ignition system of vulcanized rubber should be ≥ 20KV / mm, and the high-voltage sheath of the vehicle engine ignition system requires The withstand voltage is above 32KV; the existing relevant standards only stipulate the test methods of test blocks such as vulcanized rubber, and there is no test device and test method for the high-voltage resistance characteristics of the high-voltage sheath of the ignition system of the automobile engine
