电压击穿试验仪-击穿电压仪使电介质击穿的电压。电介质在足够强的电场作用下将失去其介电性能成为导体,称为电介质击穿,所对应的电压称为击穿电压。
电介质击穿时的电场强度叫击穿场强。不同电介质在相同温度下,其击穿场强不同。当电容器介质和两极板的距离d一定后,由U1-U2=Ed知,击穿场强决定了击穿电压。击穿场强通常又称为电介质的介电强度。
提高电容器的耐压能力起关键作用的是电介质的介电强度。附表为各种电介质的相对介电常量εr和介电强度。电介质εr击穿场强,×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.
