Abstract

A power transmission cable gallop detection device comprises a vibration sensor and a data acquirer connected with the vibration sensor, wherein the data acquirer is further connected with a GSM module, the output end of the vibration sensor is connected with the input end of the data acquire, and the output end of the data acquire is connected with the input end of the GSM module. The power transmission cable gallop detection device further comprises an alarm server used for receiving and processing information sent by the GSM module. According to the device, power transmission cable gallop is detected through the vibration sensor, the detection device is simple, convenient to use and high in operation reliability, the principle is mature, severe accidents such as severe gallop, cable breakage and outage occurring on a power transmission cable can be found out in time and handled, and great loss is avoided.

Description

technical field [0001] The invention belongs to the field of electronic communication, and relates to a detection device for galloping of a power transmission cable. Background technique [0002] Since the 1950s, with the development of the power system and the extensive construction of ultra-high voltage lines, galloping accidents have become increasingly frequent and their intensity has increased significantly, which has become one of the most important factors threatening line safety. China is one of the countries where galloping occurs most frequently. According to available statistics, since 1957, there have been about 70 galloping occurrences in our country, involving almost every voltage such as 10, 35, 44, 66, 110, 220, 500kV, etc. grade power lines. Especially in recent years, under the influence of disastrous meteorological conditions, serious galloping accidents have occurred in my country almost every year. The most serious one was the snow disaster in the south...
