Micro meteorological online monitoring system for transmission lines

The micro meteorological intelligent monitoring system for transmission lines collects and compresses parameters such as environmental temperature, humidity, wind speed, wind direction, rainfall, and atmospheric pressure through online monitoring. The data is transmitted to the monitoring center through communication methods such as GSM/GPRS/CDMA, and the analysis and query system comprehensively analyzes the data. All data is displayed to users through various reports, statistical charts, curves, etc. When abnormal situations occur, sound and light alarms are used, and the alarm information is sent to relevant personnel's mobile phones via SMS.

Product Features

The system mainly consists of three parts: monitoring unit, communication base station, and analysis and query system. The monitoring unit is installed on the transmission tower to monitor parameters such as environmental temperature, humidity, wind speed, wind direction, rainfall, and atmospheric pressure. The communication base station is installed in the monitoring center and is responsible for receiving data from various monitoring points and issuing commands from the center. The analysis and query system is installed in the monitoring center computer, responsible for storing, analyzing, and querying various data information. Through this system, timely access to meteorological data in the micro meteorological area of the line can be obtained, and response measures can be formulated in emergency situations; It can also accumulate a large amount of meteorological data for a long time to provide a basis for the planning and design of the line and the implementation of state maintenance.

Online Monitoring System for Tilt of Transmission Line Towers

Transmission lines are basically overhead lines. Since the lines are erected in the air and need to bear the effects of mechanical forces such as dead weight, wind, rainstorm, ice and snow, and the erosion of harmful gases such as wind and sand, the operating conditions are very bad. When transmission lines pass through unfavorable geological areas such as desert zones, high salt soil areas, goaf areas, and mountainous landslide areas, under the influence of natural environment and external conditions, tower foundations are prone to sliding, tilting, cracking, and other phenomena, which can cause tower deformation, tilting, and even collapse and breakage. The tilt of the tower causes uneven stress on the tower's grounding wire, resulting in changes in the tower's stress and insufficient electrical safety distance, which affects the normal operation of the line. The collapse of the tower and disconnection will cause the power supply line to be paralyzed, seriously affecting people's production and life, and causing huge losses.

Product Features

The system mainly includes two parts: tower online monitoring device and backend comprehensive analysis software. The system measures and reports various state variables of the tower, and transmits the data to the backend comprehensive analysis software system through 3G/GPRS/CDMA and other methods for analysis and decision-making, accurately reflecting the current various states of the tower. This enables system managers to grasp the actual operation situation, help them make decisions and safety assessments, and is of great significance in preventing tower accidents.

Online monitoring system for ground distance of overhead optical cable

With the gradual deepening of the construction of supporting smart grids, power communication optical cable lines not only serve as the supporting foundation of smart grids, but also the intelligent operation level of optical cable lines themselves is a component of smart grids. Communication towers located in areas with high pedestrian activity and natural disasters are highly susceptible to external damage. They are often scratched by passing vehicles due to insufficient distance between the optical cable and the ground, which can even cause serious traffic accidents and affect the safe operation of the power grid.

Grounding Resistance (Current) Online Monitoring System

In the design of overhead transmission lines, lightning protection design is an important factor that must be considered. With the development of the power system, accidents caused by lightning strikes on transmission lines are increasing. According to data, lightning strikes account for about 40% to 70% of the total tripping times of high-voltage transmission lines in China. Especially in areas with strong lightning activity, high soil resistivity, and complex terrain, the accident rate caused by lightning strikes on transmission lines is higher, resulting in huge economic losses. The purpose of grounding the overhead transmission line tower is to guide the impulse current or lightning current through the natural grounding and artificial horizontal grounding body of the tower foundation into the ground in the event of lightning strikes, in order to protect the safety of the equipment.

Product Principle

The grounding resistance (current) online monitoring system adopts the excitation method to collect the grounding resistance (current) values through GPRS communication network or wired, and sends the grounding resistance monitoring results at regular intervals to achieve remote multi-point online monitoring. The monitoring software can display the measured grounding resistance value in real time, and the automatically recorded and stored data can generate reports for easy storage, historical data query, printing, analysis, etc.
