Description
Technical Field
The invention relates to the technical field of high-speed switches, in particular to the technical field of electromagnetic repulsion mechanisms built by angle steel.
Background
The principle of high speed switching is to utilize eddy current fields to rapidly convert capacitive energy into kinetic energy of moving parts. In order to ensure the rapid action of the repulsion mechanism, the electromagnetic repulsion reaches the magnitude of tens of kN already when the capacitor discharges for hundreds of microseconds. When the technology is applied to an alternating current switch, as the alternating current breaker is three-phase, transient force possibly exists in the motion process, and the transient force can bring serious influence on the stability of the mechanism. Specifically, the motion part is mostly a whole transmission part formed by connecting transmission rods of three repulsion mechanisms, and 3 repulsion coils discharge to generate 3 electromagnetic repulsion forces to act on the whole transmission part. The three-phase repulsion mechanism cannot be concentrated for the following reasons, so that the epoxy plate and the epoxy sleeve which play a supporting role have great hidden danger to the action characteristic of the mechanism due to poor stability. 1. The three-phase repulsion mechanism cannot be made to be too small and exquisite due to the electrical distance, and the transmission part is often very large. 2. The size of the electromagnetic repulsion force is influenced by the actual resistance, the initial gap and the like of the coil, and the three-phase repulsion force cannot be completely consistent. 3. Due to factors such as volume and assembly, three-phase mechanisms are generally not made completely symmetrical.
The angle steel is a material with good stability and low cost, and a mechanism formed by welding the angle steel has very good stability. The angle steel welded frame is formed at one time, the steel structure is characterized by saving a lot of troubles in assembly, and compared with a plastic shell type circuit breaker, the angle steel welded frame is lower in cost and equal to a plastic shell in reliability.
