If testing capacitor is three termination capacitors, three terminals of capacitor distinguish terminal X, terminal Y, terminal Z；It presses
It is measured according to following steps:
Step 1: capacitor is placed on specified location, measuring head 7 is controlled using single-acting spring reset cylinder 5 and is declined,
So that the dynamic connector 72 of terminal X insertion first neutralizes the contact of the first copper sheet 722, the dynamic connector 74 of terminal Y insertion second neutralizes the second bronze medal
Piece 742 contacts, and terminal Z is inserted into the dynamic connector 76 of third and contacts with third copper sheet 762；First capacitor table 21 is first opened, can be measured
The capacitance of X-Y；First capacitor table 21 is closed, the second capacitance meter 22 is opened, the capacitance of X-Z can be measured；It is then shut off the second capacitor
Table 22 opens the first pressure tester 31, can measure the withstand voltage value of X-Y；The first pressure tester 31 is turned off, opens second
Pressure tester 32 can measure the withstand voltage value of X-Z, be then shut off the second pressure tester 32.
Step 2: only needing to rotate to the left or to the right if constituting equilateral triangle between terminal X, terminal Y, terminal Z
60 degree of capacitor, so that the dynamic connector 72 of terminal Y insertion first neutralizes the contact of the first copper sheet 722, terminal Z is inserted into the second dynamic connector 74
The contact of the second copper sheet 742 is neutralized, the dynamic connector 72 of terminal X insertion first neutralizes the contact of the first copper sheet 722, is again turned on first capacitor
Table 21, measured value M, if M value is all different with the capacitance of X-Y in step 1 or the capacitance of X-Z, M value is the capacitor
Y-Z capacitance in device；It is then shut off first capacitor table 21, the first pressure tester 31 is opened, the withstand voltage value of Y-Z can be measured.
If M value is identical with the capacitance of X-Y in step 1, at this point, closing first first capacitor table 21, it is then then turned on second
Capacitance meter 22, measured value N, if N value and the capacitance of X-Z in step 1 are unequal, N value is Y-Z capacitance.If N value
It is equal with the capacitance of X-Z in step 1, then illustrated capacitor during rotation, due to maloperation make terminal X, terminal Y, end
There is mistake in the line that the first dynamic connector 72, the second dynamic connector 74, third in sub- Z and measuring head 7 move connector 76, then must be again
Step 2 is repeated, the connection of three terminals and measuring head 7 of careful sensing capacitor guarantees that terminal Y insertion first is dynamic and connects
First 72 neutralize the contact of the first copper sheet 722, and terminal Z the second dynamic connector 74 of insertion neutralizes the contact of the second copper sheet 742, terminal X insertion the
One dynamic connector 72 neutralizes the contact of the first copper sheet 722, repeats step 2, can measure the Y-Z capacitance in the capacitor.Similarly,
The withstand voltage value of the Y-Z in the capacitor can be measured.
Wherein, if terminal X, terminal Y, constitute between terminal Z is not that equilateral triangle or replacement are different types of
Come when measuring, the type of capacitor is different, the spacing and arrangement mode between three terminals of capacitor can then occur capacitor
Variation, and the first dynamic connector 72, the second dynamic connector 74, third are moved connector 76 and can be moved along the direction that annular groove 711 limits, it can
Connector 76 is moved by the first dynamic connector 72 of rotation, the second dynamic connector 74, third, enables the measuring head 7 smoothly and capacitor
Terminal holding circuit it is unobstructed；Insulating substrate 71 serves not only as carrier, but also it is dynamic to be able to maintain the first dynamic connector 72, second
Connector 74, third are moved mutually indepedent between connector 76；The conducting wire for connecting each electric equipment can be pacified by the first mounting hole 712, second
It fills and completes to be electrically connected between hole 724, third mounting hole 744, the 4th mounting hole 764 and different electric equipments；First sliding block 723
Top and annular groove 711 slot bottom between keep enough gaps, then can guarantee the first dynamic connector 72 rotation when flexibility；
Similarly, enough gaps are kept between the top of the second sliding block 743 and the slot bottom of annular groove 711, then can guarantee the second dynamic connector
Flexibility when 74 rotation；Enough gaps are kept between the top of third sliding block 763 and the slot bottom of annular groove 711, then can be protected
Demonstrate,prove flexibility when third moves the rotation of connector 76.
When testing capacitor is both ends sub-capacitor, it is only necessary to it rotates the second dynamic connector 74 or third moves connector 76, it will
First dynamic connector 72 and the second dynamic connector 74 are maintained at same diameter or the first dynamic connector 72 and third is moved connector 76 and is maintained at
Same diameter.Measuring process is exemplified below: capacitor being placed on specified location, utilizes single-acting spring reset cylinder 5
It controls measuring head 7 to decline, so that two terminals of capacitor are inserted into respectively in the first dynamic connector 72 and the second dynamic connector 74, first open
First capacitor table 21 is opened, capacitance can be measured；First capacitor table 21 is closed, the first pressure tester 31 is opened, resistance to electricity can be measured
Pressure value.
The capacitor measuring device is not only simple to operate, and can also be used in all types of both ends sub-capacitors
