Gush circuit and its method of testing.
Background technology
Ignition coil is mainly used in being provided to spark plug in cylinder spark stroke in petrol engine as auto parts and components
High voltage.It is coupled to form by primary and secondary coil inside ignition coil, can be exported up to 27kV's according to transformer principle
High-tension electricity.
, used as ignition coil inside key components and parts, technique is accurate, by fine copper wire on secondary coil support for secondary coil
Coiling is formed.Fine copper wire technology controlling and process required precision in winding process is high, does not allow to occur cross-slot, the face internal flaw such as tiltedly.
It is difficult to detect the internal flaw of coil by effective detection means because the coiling number of plies is intensive, in daily production.
The content of the invention
The present invention can effectively detect whether secondary coil has inside to overcome the deficiencies in the prior art, design one kind

To achieve the above object, a kind of surge circuit for detecting ignition coil secondary coil defect, including power supply, electricity are designed
Hold, first switch, second switch, secondary coil, it is characterised in that：The output end of the power supply connects one end of first switch,
The other end of first switch is divided into two-way and connects one end of electric capacity and one end of second switch respectively, the second switch it is another
One end of end connection secondary coil, the other end of secondary coil is connected with the input of power supply；The other end of the electric capacity is divided into
Two-way is simultaneously connected with the input of power supply and the other end of secondary coil respectively.
A kind of method of testing of the surge circuit for detecting ignition coil secondary coil defect, it is characterised in that including following step
Suddenly：
Step 1, obtains the standard measuring signal of qualified secondary coil；
Step 2, confirms secondary coil conducting to be measured；
Step 3, the two-way terminal of secondary coil to be measured is put into test circuit；
Step 4, tests the resistance of secondary coil to be measured, if secondary coil to be measured resistance test result normally if perform step
5, on the contrary terminate test；
Step 5, is circulated now, successively to the test that 1.7kV or 2.5kV is input into the terminal all the way of secondary coil to be measured
Voltage pulse, then to the test voltage pulse of same input 1.7kV or 2.5kV in another road terminal of secondary coil；
Step 6, reads the surge test signal of secondary coil to be measured, and compares with standard measuring signal.
The step 5 comprises the following steps：1 turns on first switch, and second switch is disconnected, and now power supply fills to electric capacity
Electricity is to given voltage；2 after electric capacity charges and reaches given voltage, and first switch disconnects, and second switch conducting, electric capacity starts to point
Fiery coil discharge.
Compared with the existing technology, the testing time is short, and accuracy rate is high for the present invention；Secondary coil internal flaw is solved to be difficult to visit
The problem of survey, method of testing is simple, can replace visually inspecting completely, while improve production efficiency.
