電壓擊穿試驗儀-擊穿電壓儀使電介質擊穿的電壓。電介質在足夠強的電場作用下將失去其介電性能成為導體,稱為電介質擊穿,所對應的電壓稱為擊穿電壓。
電介質擊穿時的電場強度叫擊穿場強。不同電介質在相同溫度下,其擊穿場強不同。當電容器介質和兩極板的距離d一定后,由U1-U2=Ed知,擊穿場強決定了擊穿電壓。擊穿場強通常又稱為電介質的介電強度。
提高電容器的耐壓能力起關鍵作用的是電介質的介電強度。附表為各種電介質的相對介電常量εr和介電強度。電介質εr擊穿場強,×106/(V·m-1)

Operation procedure of voltage breakdown tester:
1. Preparation before test: 1) open the main power switch on the right side of the test machine and preheat for 15 minutes. 2) turn on the computer and enter the Windows system. Double click the instrument software shortcut icon, open the test login screen, enter the login password, you can enter the test interface.
2 、 AC and DC test switch 1) this instrument high voltage output is AC voltage. The way to obtain DC is to connect the high voltage silicon stack into the original circuit, so that the test circuit is a pulsating DC voltage. The implementation process, has been in a high voltage silicon stack transformer insulation tower, usually with a short rod, short circuit high-voltage silicon stack. When the DC test is needed, the short circuit rod is removed so that the high voltage silicon stack is connected to the test circuit, and the voltage of the circuit is a pulsating DC voltage.
2) front panel DC AC select button. The status of the button cannot change the voltage characteristic of the device output. Press this button, the device is only to connect the DC alarm circuit. Instructs the user when you open the door of the box, you need to discharge the ball evenly under high pressure. Turn off the pole so that the end of the pole is in contact with the high-pressure ball. It is recommended that each user discharge copper balls in contact with high pressure equal pressure ball for more than five seconds.
3) the AC / DC voltage switching of the test mainly depends on whether the short rod in the high voltage insulated tower is taken out. When the short circuit rod is taken out, the voltage on the ball is a direct current voltage, and when the short circuit rod is inserted, the voltage on the high voltage equalizing ball is an alternating voltage. Take out the short pole and insert it. See the diagram on the left.
4) in the DC test, the computer should also choose the DC state, otherwise the result of measurement is incorrect. In brief, the AC voltage is twice as much as the DC voltage.
Voltage breakdown test instrument is a high voltage output device. Installation, movement and use should pay special attention to the safety of people and equipment. Please note the following:
1 equipment must be connected to 16A single-phase 220V AC socket.
2 one of the two grounding terminals of the equipment must be connected to the ground wire of the distribution box through a dedicated earth wire.
3 before use, one of the two grounding terminals must be connected with the discharge rod.
4 in the test, if the observation current is maintained at 20-30mA for a long time, the test should be stopped immediay so as not to overload the fire tube.
5 a test finished, be sure to unplug the residual charge and then put off the high voltage output end of the bar.
6, in case of emergency, should immediay press "emergency stop" button, power failure.
7 do not use for a long time, disconnect all power lines.
8, handling can not tilt too large angle, so as not to transformer oil flow.
In 9 samples, make sure you've let the electric discharge rod, and the power is disconnected.
10 test process, in case of fire, be sure to break the power supply, and then extinguish the fire.
