Problems solved by technology

The air gap in the initial stage of the existing relay operating mechanism is relatively large, and the output force is small in the initial stage, so it is difficult to complete the relay drive under the large stroke. Large gap reluctance is not conducive to high-speed start-up, and the response time is slow. The existing relay operating mechanism lacks an operating mechanism with short excitation time, fast response speed, and long stroke to meet the needs of sensitive loads.
In addition, the miniaturization of the operating mechanism has become the general trend. The uneven distribution of the magnetic induction intensity inside the existing electromagnetic mechanism causes a serious waste of space resources, which is not conducive to the miniaturization of electronic equipment and the whole machine
[0003] Millisecond-level power outages in data centers in the IT industry will cause data congestion and cause large economic losses. Therefore, high-reliability power supply structures are often required in power distribution systems, so sensitive loads require dual power supply structures.

Abstract

The invention discloses a dual-power-supply switching relay operating mechanism, a switching topological structure and method. The operating mechanism comprises a yoke, a coil, a static iron core, a movable iron core and two groups of permanent magnet pairs, and the static iron core and the two permanent magnets form an inner magnetic pole group, the coil and the movable iron core are sleeved on the inner magnetic pole group, the two permanent magnets and the yoke are arranged outside the coil and the movable iron core, the coil and the movable iron core can move between the inner magnetic pole group and the other two permanent magnets, and an air gap is not changed during movement. Due to the fact that the air gaps of the magnetic poles are not changed in the movement process of the coil and the movable iron core, the excitation time of the mechanism can be effectively shortened, the rapid movement of the relay is accelerated, and the relay operating mechanism can adapt to the long-stroke scene.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a relay operating mechanism for dual power supply switching, a switching topological structure and a method. Background technique [0002] A relay is an electronic control device, a driving device that controls a large current with a small current. The air gap in the initial stage of the existing relay operating mechanism is relatively large, and the output force is small in the initial stage, so it is difficult to complete the relay drive under the large stroke. Large gap reluctance is not conducive to high-speed start-up, and the response time is slow. The existing relay operating mechanism lacks an operating mechanism with short excitation time, fast response speed, and long stroke to meet the needs of sensitive loads. In addition, the miniaturization of the operating mechanism has become the trend of the times. The uneven distribution of the magnetic induction intensity insid...
