Fig. 2 represents spark coil testing property circuit of the prior art.
Embodiment
Be elaborated below in conjunction with the preferred implementation of accompanying drawing to spark coil testing apparatus of the present utility model.
Fig. 1 shows the circuit structure of spark coil testing apparatus of the present utility model.As shown in the figure, be connected with spark coil to be tested in the circuit.This spark coil comprises primary air 2a, iron core and secondary winding 2b.The structure of spark coil is known, so in this detailed.
The spark coil testing apparatus comprises primary circuit and secondary loop.Be provided with power supply 1 in primary circuit, the minus earth of power supply 1, the positive pole of power supply 1 are connected to the end of primary air 2a, and the other end of primary air 2a is connected to ignition switch.In the present embodiment, ignition switch is made of with the waveform generator 4 that is connected on this IGBT3 IGBT (igbt) 3, the grounded-emitter connection of IGBT, 4 couples of IGBT of waveform generator send EST (Electronic Spark Timing) signal, the conducting of control IGBT3 and ending and is controlled outage, the energising of primary circuit thus.But be not limited to this, under the situation that adopts other any form ignition switch, can use technology of the present utility model.
In the secondary loop, the end ground connection of secondary winding 2b, a be connected in parallel end of first branch road and second branch road of the other end, the other end ground connection of first branch road and second branch road.Wherein, be provided with two igniting polar 5a, 5b in first branch road, separate spacing between these two igniting polar 5a, 5b, and this spacing can be regulated.And then, in first branch road, be connected in series auxiliary resistance 6 with above-mentioned two igniting polar 5a, 5b.In second branch road, divider resistance 7 and shunt resistor 8 are being connected in series.
Auxiliary resistance 6 is used for measuring the igniting number of times of igniting polar 5a, 5b, that is, when lighting a fire between igniting polar 5a, the 5b, effect has voltage on auxiliary resistance 6, by writing down the number of times that occurs voltage on this auxiliary resistance 6, just can learn the igniting number of times between igniting polar 5a, the 5b.Like this, when reaching the required igniting number of times of forced aging, just can stop igniting.As an example, the parameter of auxiliary resistance 6 is 10 Ω, 25W.
The resistance of divider resistance 7 is much larger than the resistance of shunt resistor 8, and for example, the resistance of divider resistance 7 is 15000 Ω, and the resistance of shunt resistor 8 is 300 Ω.This be because, total voltage in the secondary loop (voltages at the second branch road two ends) is very high, and by the very high divider resistance of resistance 7 is set, voltage is applied on the divider resistance 7 greatly, thereby the voltage on the circuit between divider resistance 7 and the shunt resistor 8 is reduced to a smaller value.Like this, in the time need testing, test probe 9 can be connected between divider resistance 7 and the shunt resistor 8 and test the voltage in the secondary loop.
Spacing between two igniting polar 5a, the 5b in first branch road can be regulated.In the time will carrying out the forced aging of spark coil, spacing is designed to the first spacing A, and under the distance, coil can be lighted a fire during this time, be that the high pressure that produces on the secondary winding should be able to puncture air, and the electric current of primary air and the voltage on the secondary winding want to satisfy the requirement of respective point fire coil.By carrying out the igniting of set number of times, can make the spark coil forced aging.
Behind forced aging during the performance of test point fire coil, spacing between two igniting polar 5a, the 5b is made as the second spacing B, this second spacing B is greater than the first spacing A, distance down during this time, coil can not be lighted a fire, be that the high pressure that produces on the secondary winding is not enough to puncture air, but secondary voltage need satisfy the requirement of respective point fire coil.When the spacing between two igniting polar 5a, the 5b is made as the second spacing B, revises corresponding spark coil simultaneously automatically and drive parameter, the performance of coming the test point fire coil.For example, test probe 9 can be connected between power supply 1 and the primary air 2a, come the detection of primary current in loop, also test probe 9 can be connected between divider resistance 7 and the shunt resistor 8, detect the voltage in the secondary loop.By test probe 9 being connected to display unit such as oscillograph, the value or the waveform of detected curtage etc. shown, and compare with reference value or waveform, come the quality of test point fire coil performance.
More than the preferred implementation of spark coil testing apparatus of the present utility model is illustrated, but be to be noted that only unrestricted technological scheme described in the utility model of above example in order to explanation the utility model.It will be understood by those skilled in the art that distortion and improvement that all do not break away from spirit and scope of the present utility model, it all should be encompassed in the scope of the present utility model.
For example, in the above-described embodiment, in first branch road, be provided with auxiliary resistance 6, and utilize this auxiliary resistance 6 to write down the number of times of igniting, when reaching set number of times, think the forced aging of having finished spark coil, but this auxiliary resistance 6 is not essential, a scheduled time also can be set, when beginning from igniting, just think and finished forced aging through this scheduled time.
And the resistance of above-mentioned each resistance is an example, and concrete numerical value can be set according to the parameter of spark coil to be tested.
