Ice monitoring equipment

1.Ice monitoring equipment product introduction

Ice coating of transmission lines and various ice disaster accidents caused by it have seriously endangered the safe operation of my country's power system. Ice disaster accidents in my country have the characteristics of long duration, high frequency and large coverage area; severe ice covering in micro-meteorological areas will cause the electrical and mechanical performance of power transmission and transformation equipment to decrease, and severe ice covering will cause overload and uneven ice covering. De-icing at different times causes tension differences, ice-covered flashover of insulator strings and dance of ice-covered conductors, which are the main causes of ice-covered accidents.

2. Working principle of Ice monitoring equipment

The microwave icing monitoring device for transmission lines does not require power outage installation. The equipment uses unique microwave detection technology combined with temperature analysis to achieve real-time monitoring of icing conditions on various types of poles, towers, insulators, transmission lines, etc.

The system sensor uses microwave detection technology. Based on the difference in feedback signals of different substances such as ice, water, and air, the system monitors the icing information in the sensor's sensitive area, and based on the strength of the signal and the distribution of icing in the sensor's sensitive area. The information is used to calculate the ice thickness. The ice alarm value can be set according to different ice thickness information to facilitate the startup of the deicing system. The host samples, filters, amplifies, and AD converts the ice signal in real time, and then passes it through our professional After algorithm conversion, the icing rate and thickness values ​​are obtained. When the thickness of the ice reaches the preset threshold, an icing alarm signal is sent, which is then transmitted to the background through wireless networks such as 4G. Assess the hazards of icing in real time to ensure safe line operation.
