S-500电力电缆故障测距仪适合于电力电缆的高阻、闪络、断线、低阻等类型故障的测距。采用国际先进的电子测试技术和单片机技术，结合了低压脉冲反射和脉冲电流两种测试方式， 低压脉冲反射法用于电缆的低阻和断线故障测距，以及测量各种电缆的长度或波速度。脉冲电流法分为冲击高压闪络法和直流高压闪络法两种测试方法，分别用于电缆的高阻和闪络型故障测距。 主要特点 ● 智能化程度高。能够自动判断故障点是否放电，自动计算故障距离。 ● 采用电流传感器测量流过地线的脉冲电流信号，与传统的闪测仪利用电阻电容分压器测量脉冲电压信号的方法相比，接线简单、方便；而且把仪器与高压回路从电气上隔离，安全性好。 ● 采用中文菜单技术，易于掌握和使用。 ● 可以保存20个测试波形，关机后不丢失，替代打印机功能。使用时钟标志，便于翻看波形档案。 ● 采用具有背光功能的大屏幕液晶。可以通过按键调整液晶的显示亮度。 ● 采用可充电镍氢电池，自动充电管理。 技术指标 ● 测试距离：10km ● 测试： 测试距离小于1Km时，测试误差不大于±1m 测试距离大于1Km时，测试误差不大于0.5% ● 测试盲区：小于10m ● 充电时间约5小时 ● 连续工作时间大于10小时 ● 功耗：2W ● 使用环境温度：-10°C -- +40°C ● 体积：235×190×110，重量：2Kg S-500Power Cable Fault Locator A precise power cable fault locator, which is suitable for high-impedance, flashover, broken line, and low resistance, it adopts international advanced electronic testing technologies and SCM technology, and combines with a low-pressure pulse reflex and pulse current testing methods. Features: With high degree of intelligence, it can automatically determine whether the failure point discharge or not and automatically calculate the fault distance. Compared with the traditional flash measurement instrument, which use resistance and capacitance divider measuring pulse voltage signal, the current sensor with simple and convenient wiring, and good security with isolation of high-pressure equipment and the electrical circuit. English menu, easy to master and use. It can preserve 20 testing waves permanently, no loss after the shutdown, is a replacement of printer. With a clock logo, you can read waveform file easily. Using a large LCD screen with backlight. Adjusting LCD display brightness through pressing keys. Rechargeable nickel-metal hydride batteries, automatic charging management.
