摘要
Abstract
The cable fault indicator in the 10kV cable distribution network cannot collect cable - running current and fault current. The use of hard - wired forms such as the optical fiber to transmit on - site signals increases construction and maintenance work. The running ambient temperature is seldom collected on the site. And the cable fault indicator cannot work nomially. In view of the above situations,this paper introduces a method to design a remote fault indicator with the functions of telemetry and remote signaling,which depends on the current transfomier to take power and the super capacitor to store power. The fault indicator obtains energy from the 10kV cable,and with batteries as the backup power,detects the phase current and temperature indication fault in real time. This design has some practical values in that it contains several advantages such as little on - site construction and maintenance work,long service life,and great potentials to improve the portability of the equipment and to reduce the cost and energy consumption.关键词
