Ice monitoring equipment: precise warning, resisting ice and snow disasters

1、 Product Introduction

The icing of transmission lines and the various ice disasters caused by it seriously endanger the safe operation of China's power system. Ice disasters in China have the characteristics of long duration, high frequency of occurrence, and large coverage area; Severe icing in micro meteorological areas can cause a decline in the electrical and mechanical performance of power transmission and transformation equipment. Severe icing can lead to overload, uneven icing, tension difference caused by different periods of de icing, flashover of insulator strings due to icing, and dancing of iced conductors. These are the main causes of icing accidents.

2、 Working principle

The microwave icing monitoring device for transmission lines does not require power outage installation. The equipment adopts unique microwave detection technology and combines temperature analysis to achieve real-time monitoring of icing conditions on various types of towers, insulators, transmission lines, etc. The system sensor adopts microwave detection technology to monitor the icing information in the sensitive area of the sensor based on the difference in feedback signals of different substances such as ice, water, and air from microwave signals. The icing thickness is calculated according to the strength of the signal and the distribution information of icing in the sensitive area of the sensor. The icing alarm value can be set according to different icing thickness information to facilitate the start-up of the de icing system. The host samples, filters, amplifies, and AD converts the icing signal in real time, and then converts it through our proprietary algorithm to obtain the icing rate and thickness values. When the thickness of the ice cover reaches the pre-set threshold, an ice warning signal is issued, and then transmitted to the background through wireless networks such as 4G. Real time assessment of the hazards of icing to ensure safe operation of the line.
