Embodiment Construction
[0010] Magnetic operating mechanism of the present invention such as figure 1 and figure 2 As shown, the magnetic operating mechanism includes vertically arranged pillars and upper and lower cover plates 1 fixed at both ends of the pillars. Grooves are respectively provided below the upper cover plate and above the lower cover plate, and grooves are respectively provided in the grooves. Plate-shaped permanent magnet 2, the upper plate-shaped permanent magnet embedded in the upper cover plate and the lower plate-shaped permanent magnet embedded in the lower cover plate are arranged at opposite poles, that is, the same poles are opposed to form a magnetic field gap that repels each other, and the vertically arranged The outermost pillars on the left and right sides of the pillar are respectively provided with slide rails 5, and the upper and lower cover plates are provided with moving iron cores 4 that slide up and down and are transferred to the pillar slide rails. The upper ...

The invention relates to a magnetic operating mechanism, comprising vertically arranged struts and upper and lower cover plates fixed at the two ends of the struts, wherein an upper plate-shaped permanent magnet is embedded on the lower part of the upper cover plate; a lower plate-shaped permanent magnet is embedded above the lower cover plate; the same poles of the two plate-shaped permanent magnets are opposite; movable cores which are assembled on the struts through sliding up and down are arranged in the gap between the upper and lower cover plates; the movable cores are provided with magnet coils and a vertical power output shaft; and the power output shaft runs through the upper cover plate and the upper plate-shaped permanent magnet. The mechanism has the following beneficial effects that the mechanism has simple structure; the output shaft is not limited by movers and can provide high output instantly; the mechanism has less parts, so the mechanical failure probability is greatly reduced, thus avoiding the circuit breaker operating failure caused by the operating mechanism; and at the same time, the mechanism has the advantages of excellent shock and low temperature resistance, and is simple and reliable, is stable to operate and realizes real maintenance-free operation.
Description
technical field [0001] The invention relates to an operating mechanism of a high-voltage circuit breaker, in particular to an electromagnetic operating mechanism of a high-voltage circuit breaker below 10kV and a contactor. Background technique [0002] At present, the operating mechanisms used in high-voltage circuit breakers and contactors are usually hydraulic mechanisms, pneumatic mechanisms, and spring mechanisms. These operating mechanisms have complex structures and many parts. There are more and more problems, of which more than 60% are failures of the operating mechanism, mainly oil leakage of the hydraulic mechanism, air leakage of the pneumatic mechanism and tripping failure of the spring mechanism, which reduces the reliability of the circuit breaker. Therefore, the magnetic operating mechanism has gradually attracted people's attention because of its simple structure and low failure rate. However, the existing magnetic operating mechanism controls a mover conne...
