Remote monitoring system for power transmission line

Abstract

The invention provides a remote monitoring system for a power transmission line, and the system comprises a current transformer CT1, a rectification circuit REC, a voltage stabilizing circuit, a powercircuit, a detection circuit, a central processing circuit, a storage battery module, an LED drive circuit, a first LED lamp group, and a second LED lamp group. The system also comprises a protectioncircuit which is used for detecting the secondary side open-circuit of the current transformer and carrying out the protection, and a protection execution control end of the protection circuit is connected with the central processing circuit. The system can achieve the accurate detection of the electrification state of the power transmission line, can give a corresponding instruction according tothe electrification state, and can give an alarm timely, thereby effectively improving the confirmation efficiency of an accident point. The system is high in operation and maintenance purposiveness,improves the maintenance efficiency, can reduce the manpower cost, and avoids the safety hidden troubles in the line patrol and maintenance process. Moreover, the system has the self-detection and protection functions, and guarantees the continuous stable operation.

Description

technical field [0001] The invention relates to electric power monitoring equipment, in particular to a remote monitoring system for power transmission lines. Background technique [0002] The transmission line is one of the most important equipment in the power grid. The transmission line is affected by the environment during operation, and it is prone to short circuit, current jump, and circuit breaker. In the prior art, after the above-mentioned faults occur on the transmission line, Generally rely on staff to carry out line inspection, this method is very inefficient, and the labor cost is high, it is inconvenient for mountainous areas, it is difficult to do detailed inspections, and accidents are prone to occur; more importantly, when determining the power transmission After the line failure, if the current status of the transmission line cannot be accurately determined whether it is live during maintenance, it will cause serious safety hazards to the staff, and even ca...
