Distributed optical fiber communication method for wireless temperature measurement system of high-voltage power transmission line

Abstract

The invention discloses a distributed optical fiber communication method for a wireless temperature measurement system of a high-voltage power transmission line, which belongs to the field of electric power. The distributed optical fiber communication method for the wireless temperature measurement system of the high-voltage power transmission line is based on the wireless temperature measurement system of the high-voltage power transmission line. The method specifically comprises the following steps that 1, a semiconductor laser generates a narrow-pulse-width optical pulse signal, the narrow-pulse-width optical pulse signal enters an optical fiber, and generated Raman scattering light is coupled to a transmitting module through an optical wavelength division multiplexing device; 2, data acquisition and demodulation are conducted on a voltage value acquired by the temperature sensor through a DSP high-speed processing chip; and 3, the data is sent to the optical fiber through the transmitting module, is received by the receiving module, and is stored in a background database. Temperature measurement of the high-voltage line switching position of the high-voltage iron tower in a long-distance and remote area can be realized, and long-distance transmission of measured data is realized.

Description

technical field [0001] The invention belongs to the field of electric power, and in particular relates to a distributed optical fiber communication method for a wireless temperature measurement system of a high-voltage transmission line. Background technique [0002] The temperature of the joint caused by resistance, overload and other factors is too high, which makes the insulation at the joint deteriorate or burn out. Sudden failure causes fire, which brings serious unsafe hidden dangers to the industrial production site, and even leads to forced shutdown. In addition, the broken line at the jumper of the transmission line generally does not have a grounding point, so it will be difficult to locate the fault, which further prolongs the power outage time, resulting in a serious accident that cannot resume production in a short time, resulting in major economic losses and social impact. It can be seen that the jumper connector of the transmission line is a weak link in the ...
