使用前应检查连接电缆不应有断路和短路现象，倍压筒不应有凝露现象。然后将倍压筒与控制箱用七芯电缆连接好，倍压筒和控制箱必须保持足够距离。用不小于2.5mm²的铜线将被试品、倍压筒和控制箱三者可靠接地，倍压筒高压输出端经微安表与被试品连接好。接通电源开关，将仪器预热5分钟，然后设定好所需电流、电压的值，将升压电位器沿反时针方向旋转回到零位，，高压灯亮时再沿顺时针方向慢慢调节升压电位器，同时注视电流表、电压表数值，直到达到所需电流、电压值时为止。如需要输出当前电压的0.75倍值时，只要按下0.75U按键，输出便自动下降到当前电压的0.75倍值，不必调节升压电位器。<br /><br /> （注1），到设定时间后仪器便自动切断输出并报警。如要终止试验，可按绿灯键或关掉电源来关闭输出。<br /><br /> （注2）：当发生器带负载时，75%按键按下后，应按下复位键后方能使75%键弹起。否则会损坏设备。<br /><br /> 四、直流高压发生器操作步骤<br /><br /> ●控制箱上的显示灯、开关、旋钮等已标清楚，看此操作说明时请参照控制箱的面板上元器件名称使用。<br /><br /> ●倍压筒底盘侧面有（四）五芯插座为联接控制箱电缆之插座，底盘侧面有铜接线柱为接地端子作连接地线用。<br /><br /> ●附带的高压屏蔽电流表为数显微安表，表顶端上的插孔为连接被试品的线插孔，同时也作为电源开关，不用时请拔掉插头，就自动关闭电源?；坏绯厥鼻虢蟾切拢缓煤笄虢蟾切?。<br /><br /> 4.1使用前准备<br /><br /> 4.1.1试验器在使用前应检查其完好性，联接电缆不应有断路和短路，设备无破裂等损坏。<br /><br />

对小电容试品如氧化锌避雷器、磁吹避雷器等先升至所需电压(电流)的95%，再缓慢仔细升至所需的电压(电流)。然后从数显表上读出电压(电流)值。如需对氧化锌避雷器进行0.75UDC-1mA测量时，先升至UDC-1mA电压值，然后按下黄色按钮，此时电压即降至原来的75%，并在一分钟内保持此状态。此时可读取微安数。测量完毕后，调压电位器逆时针回到零，按下绿色按钮。需再次升压时按红色按钮即可。<br /><br /> 4.3.3试验完毕，将调压电位器逆时针回到零，按下绿色按钮，关闭电源开关。<br /><br /> 4.4几种测量方法<br /><br /> 4.4.1一般测量时，当接好线后，先把联接试品的线悬空，升到试验电压后读取空试时的电晕和杂散电流I’，然后接上试品升到试验电压读取总电流I1。<br /><br /> 试品泄漏电流：I0=I1–I’<br /><br /> 4.4.2当需要精密测量被试品泄漏电流时，则应在高压侧串入GL型高压微安表(见图5a)。</span></span></span><p> </p><span style="font-family: 微软雅黑;"><span style="font-size: 16px;"><p><span style="color: rgb(0, 0, 0);"><img alt="直流高压发生器厂家"
