Problems solved by technology

However, since the sag of the transmission line is an important indicator of line safety, and this indicator still uses the traditional on-site measurement method, that is, it is necessary to regularly inspect the line and measure the sag height of each transmission line on site, which has an impact on the safety of the regional power grid. It is very important. If the sag is too long, it will cause the transmission line to loosen and eventually lead to the collapse of the transmission tower, which will have a great impact on the power grid.

Embodiment

[0013] Embodiment: A sag height rangefinder 4 is installed on the transmission wire between the A transmission tower and the B transmission tower, which can regularly emit infrared rays to the earth, and a distance sensor is set inside, and a threshold value is set. If the infrared detection distance reaches the set threshold value, the distance sensor (microprocessor) will pass the corresponding distance signal to the wireless signal transmitting device 5 installed on the transmission pole through the small wireless, and the wireless signal transmitting device 5 can pass the SIM card inside to send a short message. In this way, the information of excessive sag is sent to the corresponding operation and maintenance personnel, so as to carry out corresponding defect elimination processing.

Abstract

A transmission line sag monitoring device, which includes a transmission line fixedly installed between A transmission tower and B transmission tower, a sag height rangefinder is installed on the transmission line, and the sag height rangefinder is configured And be connected with a wireless signal transmitting device that receives transmission line sag height signal, and by this wireless signal transmitting device, contact with host computer or mobile terminal with short message mode by the SIM card of setting; Described sag height range finder comprises An infrared emitting module that can regularly emit infrared rays to the ground and an infrared receiving module that receives and reflects back and is received. The infrared receiving module is connected to a microprocessor with a memory, and the microprocessor is connected to the wireless signal Launching device; it has the characteristics of simple and reasonable structure, convenient installation, timely monitoring, safety and reliability, can improve the safe operation of transmission lines, and can reduce the impact on the overall operation of the power grid.

Description

technical field [0001] The invention relates to a power transmission line sag monitoring device, which belongs to the technical field of power transmission line safety monitoring. Background technique [0002] At present, my country's power supply network has tens of millions of kilometers of transmission lines, and most of the transmission lines are distributed in remote mountainous areas. Therefore, it is very difficult for electric workers to inspect and maintain the lines. However, since the sag of the transmission line is an important indicator of line safety, and this indicator still uses the traditional on-site measurement method, that is, it is necessary to regularly inspect the line and measure the sag height of each transmission line on site, which has an impact on the safety of the regional power grid. It is very important. If the sag is too long, it will cause the transmission line to loosen and eventually lead to the collapse of the transmission tower, which wil...
