LY - CWA 01 Wireless Temperature Measurement Centralized Display Monitoring System
1. Equipment
In the power system, there are a lot of transmission processes from power plants to power transmission and transformation equipment and to end-user electrical appliances.
The variable temperature needs to be detected. High-voltage equipment connection parts such as busbar connection points, various switches, circuit breakers, main transformer bushing clamps,
High-voltage cable joints are prone to poor contact and contact due to climate changes, material aging, rust, looseness, etc.
The resistance increases. When a large current passes through, it is easy to burn out the equipment, and in serious cases, it may even cause a fire or explosion.
In view of the current status of high-voltage equipment temperature monitoring, our company has launched a high-voltage electrical contact temperature online monitoring system to solve
The conventional temperature monitoring methods have the problems of heavy workload, inaccurate measurement, and untimely measurement.
The online temperature monitoring system consists of a server backend and wireless temperature measurement equipment. Users can use the backend software to understand the wireless temperature measurement
The temperature data reported by the equipment is used to analyze the operating status of the high-voltage equipment.
Wireless temperature measurement equipment can be installed at the connection part of high-voltage equipment to dynamically track the operating status of temperature rise fault points in real time.
Tracking monitoring can not only prevent and eliminate such accidents, but also provide safe and reliable analysis and scientific adjustment of power systems.
Provide important basis for decision making .
