Science and Technology Project \"12kV Intelligent Integrated Permanent Magnet Vacuum Broker Research \" successfully passed the acceptance review.
On November 5, 2019, New Concept Electrical Co., Ltd. participated in the Shenzhen Power Supply Bureau Organized \"12KV Intelligent Integrated Permanent Magnet Vacuum Broker Research \" Project \ Technical Project Acceptance Review Association \".
This project has studied a medium-voltage circuit breaker that meets electromagnetic compatibility requirements, and has developed a set switch body, isolation switch, circuit breaker, circuit breaker, circuit breaker, circuit breaker, circuit breaker, circuit breaker, open circuit. A new 12kV intelligent integrated permanent magnet vacuum circuit breaker, two sets of protection and measurement of two sets of protection and measurement, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers, circuit breakers. Apparatus, alternate power supply, etc. have functions such as power generation, breaking and measurement, control, protection, communication. Realizing the non-station plug-and-play operation and test mode of the protection measuring device, realizing remote monitoring and online information sharing of protection measurement device under wireless transmission. The project results passed the third-party test, and the Songgang Branch of Baoan Power Supply Bureau in Shenzhen is in recent 2 months, and the operation is good.
Project results innovation:
- First, cancel the secondary loop, completely eliminate secondary loop defects and hidden dangers.
- Second, two sets of protection and measuring devices are mainly prepared, using seamless switching operations, ensuring that protection and measuring devices do not lose protection during N-1 damage or defects.
- Third, realize the replacement or maintenance protection and measurement device by plugging without power failure.
To protect the results, the new concept electrical and limited company and the project partner Shenzhen Power Supply Bureau Co., Ltd. and apply for 5 invention patents and 6 practical new patents. The number of patents far exceeds 3 utility model patents in planning. index.
The evaluation team expert consists of the National Grid Corporation and Southern Power Grid 1 and Level 2. The assessment team experts agreed that the overall research results of the project reached the expected goals, and the project results will lead the development trend of distribution network circuit breakers.
