Technical Field
[0001] This utility model relates to the technical field of distributed fault monitoring devices, specifically a weather-resistant distributed fault monitoring device for transmission lines. Background Technology
[0002] With the continuous expansion of the power system and the increasing complexity of the power grid structure, rapid and accurate fault location has become the key to ensuring power supply reliability. As a new type of monitoring technology, distributed fault location devices provide an efficient solution for power operation and maintenance through multi-point collaborative sensing and intelligent analysis. Distributed devices can complete the initial location within 10 seconds after a fault occurs, greatly shortening the power outage time.
[0003] However, traditional distributed fault monitoring devices have the following drawbacks:
[0004] Traditional distributed fault monitoring devices are placed close to the power transmission line for monitoring. When power is transmitted through the power transmission line, the temperature rises. The monitoring device operates under high temperature conditions for a long time, and the sensitivity of the sensor gradually decreases, affecting the accuracy of the monitoring device. Utility Model Content
[0005] The purpose of this invention is to provide a weather-resistant distributed fault monitoring device for transmission lines, in order to solve the problem mentioned in the background art that traditional distributed fault monitoring devices are placed close to the transmission line for monitoring. When power is transmitted in the transmission line, the temperature rises, and the monitoring device operates under high temperature conditions for a long time, which gradually reduces the sensitivity of the sensor and affects the accuracy of the monitoring device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a weather-resistant distributed fault monitoring device for transmission lines, comprising a first monitoring shell, a second monitoring shell hinged to one end of the first monitoring shell, monitoring slots formed in the middle of one side of the first monitoring shell and the middle of one side of the second monitoring shell, length rods fixedly installed at the bottom of the inner walls of the two monitoring slots, length blocks slidably connected to the middle of the two length rods, a monitoring component fixedly installed between the two length blocks, a cooling component fixedly connected to the surface of the first monitoring shell and the surface of the second monitoring shell, each cooling component comprising a cooling housing and a micro battery, perforated cooling plates fixedly installed on both sides of the inner wall of the cooling housing, and the interior of the cooling housing fixedly connected to one side of the micro battery.
