Problems solved by technology

However, the ability of the armored optical fiber to sense the vibration signal is weak, so the vibration signal of the armored optical fiber cannot be sent out in time and transmitted to the alarm system, resulting in a high frequency of theft.

Abstract

The invention relates to an excitation device. The excitation device includes an adsorption part arranged on the ditch cover, a transmission wheel arranged in the ditch, a matching part, a first transmission shaft, a second transmission shaft and a sensing part. The absorbing part is arranged on the canal cover, and the absorbing part is set opposite to the driving wheel at intervals, and is arranged eccentrically relative to the driving wheel. The matching part and the center of the drive wheel are misplaced, and the matching part and the absorbing part can generate magnetic force. The second transmission shaft is parallel to the first transmission shaft and arranged at intervals, and is distributed on opposite sides of the transmission wheel. Both the first transmission shaft and the second transmission shaft are configured to abut against the outer circumference of the transmission wheel under the action of an external force noodle. The sensor is connected between the first transmission shaft and the second transmission shaft. The excitation device provided by the invention has good timeliness.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an excitation device. Background technique [0002] With the development of power technology, the power supply network formed by cables is also widely used in urbanization construction, and the normal operation of cables has become a strong guarantee for economic and social development. The cables are generally arranged in the ditch, and the cables are protected by covering the ditch cover above the ditch. However, even so, the theft of cables still occurs from time to time. In order to reduce the frequency of cable theft and ensure the normal operation of cables, various cable safety detection devices have emerged as the times require. [0003] The traditional detection device is to use armored optical fiber to directly lay out along the periphery of the cable. The optical fiber judges the theft behavior through the mechanical vibration transmitted by the soil, and tra...
