Problems solved by technology

However, the functions and applications of insulation testing equipment currently on the market are not suitable for the insulation testing requirements of ignition coils
First, the test voltage cannot reach the high voltage of 30KV, which cannot simulate the actual working condition of the ignition coil; second, only one part of the insulation performance can be tested at a time, and the operation is cumbersome and inefficient

Abstract

The invention relates to an automobile ignition coil insulation performance test board and a using method. The automobile ignition coil insulation performance test board comprises a timer, a signal generator, a cable, a steel ball groove, a steel ball, a sensor, and an oscilloscope. A steel ball is arranged in the steel ball groove, the signal generator is electrically connected with the timer; the timer is connected with one end of the cable; the other end of the cable is used for stripping a cable sheath to be connected with a to-be-measured ignition coil, the outgoing line of the sensor isfixed on the outer shell of the steel ball groove, and is electrically connected with the steel ball groove shell to be grounded through the sensor, and the signal output end of the sensor is connected with the oscilloscope. The steel ball serves as a test medium, when the 30 KV high voltage is generated in the ignition coil, the steel ball generates a discharge phenomenon, and the insulation performance of the ignition coil is tested through the discharge pulse, the ignition coil insulation instrument has the beneficial effects that the problem that the overall insulation performance of the ignition coil is tested is effectively solved, the performance is stable and reliable, the test is accurate, the operation is simple and convenient, and the test efficiency and level are improved.

Description

technical field [0001] The invention relates to a gasoline engine ignition coil, in particular to an automobile ignition coil insulation performance testing platform and a use method. Background technique [0002] The ignition coil is an important component of the gasoline engine ignition system, and its insulation performance is directly related to the operating conditions of the vehicle. When the ignition coil is working, an ignition voltage of about 30KV will be generated inside, and the ignition voltage will be transmitted to the spark plug to ignite the fuel mixture in the engine cylinder to make the car run normally. We must ensure that the ignition voltage will not be released on other parts of the ignition coil, so it is necessary to test the overall insulation performance of the ignition coil. However, the functions and applications of insulation testing equipment currently on the market are not suitable for the insulation testing requirements of ignition coils. F...
