New Concept Electric Inc.
Electrical & Electronics
The permanent magnet mechanism has few components(about 7% of spring mechanism), simple structure, high reliability, long service life (long mechanical life of up to 100,000 times), maintenance-free, electronic software control, so its prospect is very broad, and the permanent magnet mechanism can be divided into monostable and bi-stable permanent magnet mechanism. Their functions are almost the same, but monostable mechanism has one less magnetic circuit, so that its voloum is 50% less than bi-stable permanent magnetic mechanism. Our company use monostable permanent magnetic mechanism. Based on the number of coil, the permanent magnet mechanism is divided into a double coil permanent magnet mechanism and a single coil permanent magnet mechanism. This kind of permanent magnetic actuator is firstly designed by our company, and instead of spring operation mechanism, it has low failure rate, high open and close speed, and maintenance-free characteristics. It is the best choice for future acutator equipments. Low failure rate and maintenance reduce labour and resource cost for customers and potential risk for maintenance people. High close and open speed make fast protection function possible, avoid step over trip, and improve efficiency of power grid and life quality of citizens. Right now, we are cooperating with Beijin Hezong, Zhongneng, Nanrui and other big companies, and occupy a large market share.
