The invention discloses an intelligent failure monitoring device for power transmission and transformation. The device includes a current transformer, an insulation support rod, a zero-sequence current monitoring module and a background service management monitoring server. The lower end of the current transformer is provided with the insulation support rod. A zero-sequence current monitoring module is connected with a failure monitoring and processing module electrically through a signal cable. The failure monitoring and processing module is connected with a wireless GPRS module electricallythrough a communication cable. An annular housing is arranged on the outer side of the current transformer. The annular housing is therein provided with epoxy resin and an annular silicon steel iron core is mounted in the annular housing. The outer surface of the annular silicon steel iron core is coiled with an induction coil. According to the invention, the current transformer is a precision current transformer mounted on a cable grounding wire and thus outputting current signals sensed on the grounding wire via a second ary terminal, so that signal loss during transmission is prevented andsignal accuracy is ensured.
Description
technical field [0001] The invention relates to the technical field of intelligent fault monitoring, in particular to an intelligent fault monitoring device for power transmission and transformation. Background technique [0002] Power transmission and transformation is the crucial material basis for improving the reliability of power supply, and the last barrier to improve the disaster prevention and resilience capabilities of the power grid and ensure uninterrupted power supply for end users. Due to the complex structure of power transmission and distribution lines, numerous branches, and the complex and changeable environment where overhead lines pass, it is easy to be affected by the external environment or human factors and cause line faults. Due to the wide coverage of power transmission and transformation and the limitation of automation level, it is difficult to meet the increasing demand for power transmission and transformation operation and maintenance.
