Grid ice disaster refers to the power system failure caused by ice on transmission lines due to low temperature rain, snow and freezing weather. This phenomenon usually occurs in winter, especially the temperature at about zero degrees and accompanied by precipitation period, sleet, freezing rain or drizzle is the conductor over ice "partner", this kind of precipitation form in the fall to the conductor, because of the lower temperature, it is easy to freeze in a short time, the formation of serious ice conditions. In China, the power grid ice disaster is mainly concentrated in Hunan, Guangxi, Guizhou, Sichuan, Chongqing, Yunnan, Hubei, Anhui, Jiangxi, Zhejiang, Fujian and other provinces, these areas because of the topography and climatic conditions are particularly susceptible to the impact of the ice disaster, especially in the mountainous, hilly areas and rivers and lakes near the overhead power lines, power towers.



Ice storms affect the grid in many ways, including but not limited to:

I. Damage to the physical structure

1,Thick ice could crush transmission line support structures such as transmission towers and line poles, causing equipment to collapse or break.

2. Snow and ice adhering to the surface of the equipment increases the weight and deforms or shifts the equipment, further aggravating the risk of physical damage.

3, insulation degradation: Ice cover will lead to electrical insulation of power equipment insulators, cables and other components of the electrical insulation performance decline, increasing the risk of electric shock and short circuit.


II. Impaired electrical performance

1, power supply interruption: after the transmission line is covered with ice, the line impedance increases, power transmission is blocked, which may lead to power supply interruption in severe cases. This has a serious impact on people's lives and industrial production.

2. Ice-induced short-circuit failures are also one of the major causes of power supply interruptions, and often the load on the grid may rise sharply as a result of increased demand from users for heating and other purposes.


III. Reduced operational performance

1. Low-temperature environments may lead to a decline in the performance of power equipment, affecting its normal operation, and the maintenance and repair of power equipment becomes exceptionally difficult during ice storms due to icy roads and transportation disruptions. This further exacerbates the problem of degradation of the operational performance of the power grid.

 

Aiming at the current situation of lack of historical meteorological observation records of transmission lines and insufficient monitoring accuracy,brings you a series of series of meteorological observation records of transmission lines. ">has brought a series of online monitoring equipment for power grid ice cover, including transmission line equivalent ice cover online monitoring device, visualization mobile ice cover monitoring device, microwave ice cover monitoring device, ice cover elf monitoring device, which The "Ice Wizard Monitoring Device" is favored by the market for its small size, easy installation (hanging on the conductor), fast data transmission, high precision, timely warning and other functions.

Ice Cover Wizard Monitoring UnitThe DX-WPS100-JL integrates multiple functional features into one. After the image monitoring unit captures the photos of wires and channels, it sends these pictures as well as the front-end sensory information back to the server side via 4G/5G/WIFI and other communication methods. In this way, users can view the ice-covering thickness data and on-site ice-covering image video via cell phone or computer anytime and anywhere. At the same time, combined with the meteorological parameters provided by the micro-meteorological monitoring unit and the angle data measured by the inclination detection unit, as well as the wire current temperature monitoring module, the system can automatically analyze the current ice-covering situation and future trends. Once abnormal conditions are detected, the system will immediately send warning messages to users and relevant personnel in the power sector to help them take timely measures against potential risks.
