DC thermal relay calibrator

DC thermal relay calibratorIn the operation and maintenance of the power system, according to the regulations of the national power industry on the inspection of thermal relays, motor protection, and feeder protection safety automatic devices, motor protectors must undergo full inspection every year after being put into operation, as well as inspection within a certain period of time. Therefore, the inspection of motor protectors is a long-term and heavy task. In order to facilitate the effective and convenient testing of motor protectors, our company has conducted long-term experiments and specialized designs based on the performance characteristics of thermal relays and motor protectors, on the basis of the original thermal relay tester. By adopting power electronic adjustment technology, selecting imported high-power IGBT tubes, and eliminating bulky autotransformers, a new generation of lightweight and portable thermal relay tester has been developed. Compared to traditional devices that use autotransformers, it reduces weight and volume by 45%, truly achieving portability and greatly reducing the workload of on-site workers. This device is mainly used for the calibration of thermal relays, motor protectors, current type motor protectors, and thermocouples. In fact, based on a large number of experiments, the instrument has proven that it can not only test and verify all current type motor protectors, but also effectively inspect and test all overcurrent automatic protection devices. This instrument adopts microcontroller control technology in its design, making it easy and convenient to operate during use. Throughout the entire testing process, the performance is reliable and stable, and the readings are intuitive and fast. The application of high-precision sensors effectively ensures the accuracy of the test data.

DC thermal relay calibratorScope of application:

1. Suitable for testing various types of comprehensive protectors, low-voltage motor protectors, and thermal relays.

2. Test whether the motor protector effectively protects during operation.

3. Suitable for laboratory testing of low-voltage motor protection devices.

4. Suitable for manufacturers of motor protectors to conduct product quality verification, factory testing and debugging.

5. Can set the fixed value for the comprehensive protection device

6. Suitable for research and development, experimentation, and teaching in various universities and research institutions

This testing instrument is a new generation developed by the company based on feedback from users across the country and years of practical experience. It is mainly used for setting and verifying various thermal relays and motor protection devices. Due to its reasonable design, easy operation, and high output power, it is widely used in electrical testing sites of enterprises such as power systems, railways, petrochemicals, metallurgy, and mining.
