电压击穿试验仪操作步骤：

1、试验前的准备：1）打开试验机右侧的总电源开关,预热15分钟。2）打开计算机进入Windows系统。双击本仪器软件的快捷图标打开试验登录界面输入登录密码即可进入试验界面。

2、交直流试验的切换1）本仪器高压输出为交流电压。直流的获得方式为在原回路中串入高压硅堆，使测试回路为脉动的直流电压。实现的过程为，硅堆已经在高压变压器的高压绝缘塔中，平时用一个短路杆把高压硅堆短接。需要直流试验时，取出短路杆，使高压硅堆接入测试电路中，这时回路的电压为脉动的直流电压。

2）前面板直流交流选择按钮。该按钮的状态不能改变设备输出的电压性质。按下该按钮，设备仅仅是把直流报警电路接入。指示用户，当打开箱门时，您需要对高压均压球放电。转动放电杆，使放电杆的端部铜球接触高压均压球。建议用户每次放电铜球接触高压均压球时间大于五秒。

3）试验的交直流电压切换，主要取决于高压绝缘塔中的短路杆是否取出。当取出短路杆时，高压均压球上的电压为直流电压，插入短路杆时，高压均压球上的电压为交流电压。短路杆的取出、插入参看左侧的示意图。

4）在直流试验时，计算机也要选择直流状态，否则测的结果是不正确的。简单的说，交流电压与直流电压有倍的关系。

电压击穿试验仪是高压输出设备，安装搬动使用应特别注意人身与设备的安全。请注意以下事项：

1 设备务必接16A单相220V交流电插座。

2 设备两个接地端子之一务必通过地线导线接配电箱的地线。

3使用前，设备两个接地端子之一务必接放电棒。

4 试验中，观察检测电流如果长时间维持在20-30mA,应立即停止试验，以免负载过大烧毁保险管。

5 一次试验完毕，务必先断掉电源，再用放电棒放掉高压输出端的剩余电荷。

6 如遇紧急情况，应立即按压“急停”按钮断电。

7 长时间不用，断开所有电源线。

8 搬运时不能倾斜角过大，以免变压器油流出。

9 换试样前，确保已经用放电棒放过电，且电源处于断开状态。

10 测试过程如遇试样着火，务必先断电源，后灭火。

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.
