power Electrical electric temperature sensors Used for power monitoring

What are the types of temperature sensors in the power system

1. Electrical sensor components
The traditional temperature monitoring method used in the power system is achieved by using temperature sensitive components, such as thermistors. At this time, corresponding processing circuits need to be used to process the signal. Its characteristics are low reliability, poor measurement accuracy, and the need for more wires. Subsequently, digital temperature sensors emerged, improving the accuracy and intelligence of the monitoring system. In hydropower stations, this scheme has been well applied. Overall, using electrical sensors for temperature monitoring belongs to contact monitoring, which means that the sensors used have direct contact with the equipment to be monitored, converting temperature signals into electrical signals, The main advantage of using electrical sensors for temperature monitoring in power systems is their mature technology, which is displayed on on-site instruments. اما, the biggest drawback is that the resulting signal exists in the form of an electrical signal in the system. اما, the power system creates a high voltage and strong magnetic field environment, which can have a significant interference effect on the electrical signal, easily causing distortion of the resulting signal, rendering the monitoring ineffective and unstable

2. Infrared temperature monitoring system
In infrared temperature monitoring systems, there are generally non-contact infrared سنسورهای دما, data buses, and computers. These sensors can monitor the temperature of high-voltage and high current carriers, and can operate stably in strong electric field environments. Compared with traditional electrical sensors, their working mode belongs to non-contact measurement. The main drawback is that the installation of infrared temperature sensors is difficult, and real-time online monitoring cannot be achieved in unmanned substations

3. سنسور دمای فیبر نوری فلورسنت

The main advantages of سنسورهای دمای فیبر نوری are that they are less affected by humid environments, have high resistance to electromagnetic interference and good insulation, are not easily corroded, غیره. They are made of non-metallic structures and are made of chemically inert rare earth materials. Fluorescent probes can be used safely in almost any environment, and have characteristics such as no EMI interference, اندازه کوچک, high temperature measurement accuracy, fast response time, and stable performance. The probe has good flexibility, resistance to bending, and can be directly bonded to the ideal test area. It is resistant to high temperature, pollution flashover, and creep, and will not affect the insulation and voltage resistance performance of the switchgear equipment itself.
