Product Description

Products Application

Icing of power transmission lines in my country is very common. Icing and snow accumulation on power transmission lines can lead to a sharp decline in their mechanical and electrical performance, causing major power accidents such as conductor dancing, tower tilting or even collapse, line breaking, and insulator flashover, which seriously affect the safe operation of the power system. Traditional monitoring methods such as manual line inspection and ice observation stations are inefficient, time-consuming and labor-intensive, and the safety factor of operation and maintenance personnel is low. Existing icing monitoring methods based on tension and images often require untying the insulator string, which is complex to construct and poses safety risks. In addition, existing icing monitoring systems are all powered by solar energy. During icing, the monitoring system is often underpowered and cannot work properly. The more serious problem is that since the camera is in intermittent power-on working mode, the camera lens is prone to icing and cannot capture the icing situation on site.

 

Product Description

In response to the above situation, our company independently developed a remote line ice watcher. The device is directly installed on the transmission line conductor. The power supply system adopts high-efficiency AC induction power supply technology, and the power supply reliability is high. The camera lens adopts polymer organic film heating technology. The CPU can perform heating and anti-freezing operations according to the ambient temperature and humidity on site to ensure that the lens is not covered with ice. Built-in AI module, with on-site edge computing capabilities. The ice thickness can be calculated through ice image information, which is convenient for users to fully and efficiently grasp the line ice status. The device has a built-in 4G module, which can send monitoring images, videos, sensors and status information and other data to the central station through 4G transmission. It has two working modes: timed shooting and recall shooting. When the relevant collected information data exceeds the set threshold, the platform will automatically push ice status warning information to users through mobile WeChat and Web. In addition, the device can be equipped with a wireless broadband module, which can use a chained MESH network through multiple elves to realize node and routing transmission functions. It is very suitable for ice monitoring in remote iced areas without operator 4G network.

 

Our Advantages

 

Traditional ice monitoring system	Remote line ice watcher
Installed on a pole tower, powered by solar energy, unreliable in winter, requires maintenance basically once a year	Installed on the conductor, powered by inductive coupling, high reliability, maintenance-free
Basically, ordinary spherical cameras are used. The semicircular shield is easy to freeze, and it is impossible to capture the scene at the critical moment.	Inductive energy extraction, sufficient energy, continuous heating and de-icing, lens anti-freezing
The camera is installed on the tower. Although the camera has an optical zoom of more than 20X and a long shooting distance, it is difficult to see the ice condition on the ground wire after fogging during the ice-covering period.	Close-range shooting, less impact from fogging, built-in camera fog penetration algorithm, clearer images, and night shooting function
It is necessary to remove the insulator string fittings and replace them with tension sensors to calculate the equivalent ice thickness through the ice model.	There is no need to untie the insulator string hardware, the construction plan is simple, and the actual conductor ice thickness is calculated through image analysis algorithm
