With the development of society, the power system has higher and higher requirements for transmission and distribution equipment. Intelligent power equipment has attracted people's attention, and its reliability and stability have attracted attention from the industry. Network transformation, the regulator industry encountered rare opportunities, but also brought opportunities for the development and progress of electromagnetic regulator components.
For a long time, temperature control systems such as electromagnetic voltage regulators have used Pt-100 platinum thermal resistance for sampling. Some people have also studied the use of some new sensors, such as integrated temperature sensors, to meet different sampling requirements. Cost-effective, so it is still the first choice for sensors.
With the advent of 110KV high-voltage dry-type voltage regulators, platinum resistors have been unable to fully meet the requirements. If the traditional Pt-100 platinum resistance is still used for contact temperature measurement, the high-voltage winding side of the voltage regulator will damage the platinum resistance and the input circuit of the temperature control system due to the strong induced electromotive force, and burn the temperature controller chip, resulting in high-end Tripping can also cause regulator accidents in severe cases. Therefore, it is necessary to use advanced non-contact sensors and infrared temperature sensors to replace Pt-100 platinum resistance. With the appearance of various new electromagnetic pressure regulators, there will be many forms of sensors in the temperature control system.
New electromagnetic regulators are constantly emerging, and the application field is also expanding. People have put forward more and higher requirements for the centralized monitoring of the operating status of dry regulators. The installed dry voltage regulators have problems such as various distribution types, large distance differences between them, unattended operation, and multiple monitoring systems. Networking, intelligence, integration, and standardization of communications are contemporary development trends. For different applications, the temperature control system should also improve the communication structure and try to be as diverse as possible and use standard communication methods.
