The stable operation of transmission lines is the basis for guaranteeing power supply, and "three-span" lines are the top priority for grid security. The so-called "three across", that is, across the railroad, highway and important transmission corridor lines. Due to the complexity and specificity of the environment in which the "three-span" lines are located, once a failure occurs, not only will affect the stability of power supply, but also may pose a serious threat to transportation and public safety. Therefore, to do a good job of "three across" line inspection work is critical, through line inspection timely detection of equipment whether there is damage, corrosion, loose and temperature abnormalities and other hidden dangers, to ensure that the line operation is foolproof.

Challenges in the operation and maintenance of "three-span" transmission lines

1, the environment is complex: "three across" line is located in a complex environment, across the region often involves railroads, highways, rivers and other scenes, frequent changes in the surrounding environment, triggering potential safety hazards. For example, the expansion of railroads and highways, construction vehicles mistakenly entered, tree growth, ice, wind, etc. may pose a threat to line safety.

2, emergency response and disposal of difficult: "three across" line failure, may trigger a chain reaction, resulting in widespread power outages, traffic accidents and other serious consequences, the emergency response and disposal capabilities put forward higher requirements.

3, operation and maintenance difficulties: due to the special location of the "three across" line, the operation and maintenance personnel are difficult to access, inspection and maintenance work is difficult, high cost.

Response: Three-span video online monitoring device for transmission lines

Program overview

Traditional video surveillance devices cannot better solve the above difficult problems due to the lack of intelligent identification and early warning of hidden dangers on site. While Transmission Line " Three across" video online monitoring device DX-WPS100-SP9, based on wireless communication technology, through the high-definition PTZ camera real-time monitoring of transmission lines and their surrounding environment status, while having a front-end AI hidden danger recognition function, recognition of hidden danger immediately back to the alarm, to prevent the line from being damaged by external forces, theft and other accidents, to ensure the safe and stable operation of the power grid.

Functional Advantages

1, high-definition video surveillance: the use of dome camera equipped with high-precision PTZ, can be horizontal 0 ° ~ 355 °, vertical -15 ° ~ 90 ° rotation, support for 18 times the optical zoom, real-time capture the line body and changes in the surrounding environment.

2、Support the front-end 24-hour continuous video recording function, video using cyclic coverage (i.e., after the storage space is full, automatically cover the early video files), the storage capacity can meet the requirements of more than 5 days of historical video, and support remote retrieval and access.

3, Intelligent analysis and identification: AI self-learning algorithm is used, which can automatically analyze the collected video data and identify potential safety hazards, such as construction machinery, trees over height, foreign objects hanging wires, and hill fires.

4、Wireless communication: support 4G/5G/WIFI/OPGW fiber optic and other network transmission methods to ensure stable data transmission.

5、Support dynamic adjustment of the resolution and frame rate, and according to the network situation to realize dynamic adjustment and back.

6, low power consumption design: solar power supply, combined with efficient power management system, can be in the environment without utility power long-term stable operation.

Transmission line "three across the The successful application of video online monitoring devicehas fully proved its important role in guaranteeing the safe operation of power grids. In the face of growing power demand and complex operating environment, we call on more power companies to actively introduce such advanced equipment to guard the power artery in real time and enhance the intelligent operation and maintenance level of the power grid. At the same time, we will also strengthen the research and development of related technologies to provide stronger technical support for the sustainable development of the power industry.
