HIGH-VOLTAGE DEVICE FOR REGISTRATION OF DAMAGE PLACES OF INSULATING MATERIALS OF POWER CABLE LINES BY REMOTE METHOD OF DIRECT CONNECTION TO THE CABLE LINE

摘要

The utility model relates to power engineering, mainly to electrical devices, and can be used for remote detection of the place (zone) of insulation failure with high transient resistance at the place of damage to power cable lines according to the parameters of the wave process. EFFECT: increased efficiency of the process of a remote method for determining damaged sections of insulation of power cable lines with high transfer resistance at the point of damage without additional connecting high-voltage devices between the cable line and the device for determining the location of the damage. Essence: a portable high-voltage device for registering places of damage to insulating materials of power cable lines consists of a high-voltage signal matching unit and an electromagnetic wave calculation unit. The high-voltage signal conditioning unit includes a high-voltage blocking capacitor (at rectified voltage), a voltage divider, and high-voltage matching resistors of the cable line cores. The unit for calculating the electromagnetic wave includes an analog-to-digital converter, a microprocessor device, a reflectogram visualization unit, and a power supply unit. 2 ill.
