Problems solved by technology

Once tripped, affected by the pollution of insulators, it will be very difficult to close the transmission line, or even cause permanent faults, which will seriously affect the quality of power supply. It can be seen that trips caused by wildfires are more destructive than trips caused by lightning strikes.

Abstract

The invention relates to a power transmission line forest fire monitoring system based on a satellite receiving system, which comprises a satellite receiving antenna (1), a low noise amplifier (2), a data signal feeder line (3), a data input card (4), a first computer (5), a second computer (6) and a third computer (7) sequentially connected in series. The system has the advantages that various kinds of remote sensing satellite information broadcast by national satellites and meteorological satellites, the type and the quantity of received satellite information can be freely selected according to requirements, and the cost performance is high; the degree of automation is high, the requirement of timeliness can be guaranteed, and real-time early warning can be realized; system hardware is not influenced by satellite change and can be upgraded freely; and high-accuracy time reference can be provided for satellite tracking and data input, and the system stability is very reliable.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a mountain fire monitoring system for transmission lines based on a satellite receiving system. Background technique [0002] Mountain fire disasters occur frequently, and transmission lines often cross fire-prone areas. Once a mountain fire occurs, the air discharge caused by it will cause the transmission line to trip. Once tripped, due to the pollution of insulators, it will be very difficult to close the transmission line, or even cause permanent faults, seriously affecting the quality of power supply. It can be seen that trips caused by wildfires are more destructive than trips caused by lightning strikes. With the rapid development of the national economy, the demand for electricity in various industries is also increasing, and the requirements for the quality of power supply are also getting higher and higher. Therefore, the safety and stability ...
