Some people say that if the cold in the north is a physical attack, the cold in the south is magic damage. Indeed, under the same temperature, the humidity and cold make people shiver. Not only that, but also the outdoor equipment is affected. In particular, the overhead transmission lines, iron towers, towers and other outdoor equipment of the power grid. Every year, Yunnan and Guizhou, northern Guangdong and Guangxi, and eastern China often suffer from multiple rounds of cold air attacks, continuous low temperature, snow and freezing weather, resulting in local power lines icing, or even tower tilt Serious power grid accidents such as wire breakage and large area power failure.

My deep memory is about the huge ice and snow disaster around the New Year in 2008. Almost 20 provinces across the country were affected by the ice and snow disaster, among which the power grid was severely damaged, causing widespread blackouts and power rationing. Therefore, we can see that the low temperature, freezing rain, ice and snow weather is a major obstacle to the safe operation of the power grid.

It is the requirement of modern smart grid to fully master the actual situation of grid icing by relying on high-tech. Dingxin Smart Technology DX-WPS100-FB transmission line icing online monitoring device can monitor power line towers, conductors, porcelain bottles and other power equipment in real time, help the power sector to achieve online observation of grid icing, and fully master the actual situation of grid icing.

The device is composed of front-end camera, micro meteorological sensor, pull tilt sensor, solar panel, communication terminal and back-end monitoring platform. The column tension sensor is installed between the insulator string and the beam, which can monitor the line tension. At the same time, the front-end high-definition camera of the equipment can observe the line environment in real time, monitor the formation process of icing, and remind the operation and maintenance personnel by SMS, alarm prompt, mobile phone app reminder, etc.

The operation and maintenance personnel can take necessary emergency preparedness measures for the iced lines according to the on-site environmental image video and meteorological numerical forecast sent back by the transmission line icing online monitoring device, combined with the line tower terrain information.
