Abstract

A moving contact component and an electromagnetic isolation driving intelligent switch using the moving contact component. The moving contact component is used to realize the opening or closing of the moving contact of a switch or a circuit breaker. The moving contact component comprises a moving iron core (4), two permanent magnet steels (5) and an opening or closing coil (10). The moving iron core is arranged between the two permanent magnet steels. The moving iron core is fixed on a moving contact (2). The middle part of each permanent magnet steel is provided with a through-hole. The moving contact is sleeved in the through-holes. The opening or closing coil is installed on an outer wall of an insulating cavity (7).

Description

Technical field [0001] The invention relates to a power equipment technology, in particular to a moving contact assembly and an electromagnetic isolation drive intelligent switch using the moving contact assembly. Background technique [0002] The function of the switch is to cut off and turn on the circuit, and cut off the faulty circuit. The vacuum switch is named after its arc extinguishing medium and the insulating medium of the contact gap after the arc extinguishing are high vacuum. It has the advantages of small size, light weight, suitable for frequent operation, and no need for overhaul of the arc extinguishing chamber. Chinese applications are more popular. Vacuum circuit breakers mainly include three parts: vacuum interrupter (vacuum bubble), electromagnetic or spring operating mechanism, support and its transmission system. [0003] The vacuum switch has many mechanical parameters, such as closing speed, opening speed, contact stroke, contact closing bounce time, cont...
