三、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。
