Description

TECHNICAL FIELD

[0002] The transformer boosts the power generated by the generator, and then inputs the power transmission line through the control equipment such as circuit breaker, and then supplies the power to the power consumption equipment. The power transmission line is divided into overhead power transmission line and cable line. The overhead power transmission line is prone to failure due to lightning, snow and other reasons during use, and is also prone to damage and corrosion due to long-term use, resulting in burning of the power transmission line under high current and high voltage, and interruption of power supply.

However, the existing fault detection equipment is usually installed on the tower by means of a snare, so that the fault detection equipment cannot adapt to the change of the outer diameter of the tower. Since the fault detection equipment has a certain weight, the stability of the fault detection equipment during use is poor by the above installation method. When the fault detection equipment is affected by natural factors (such as wind, conductor dancing and other interference) and human factors (such as broken wood and construction equipment), the detection performance of the fault detection equipment is affected.
