Description

High speed long-life electromagnetic mechanism
Technical field:
The present invention relates to electromagnetic mechanism technical field, be specifically related to a kind of high speed long-life electromagnetic mechanism.
Background technology:
Existing electromagnetic mechanism is all utilize coil electricity that upper and lower iron core is closed, in order to remain closed, solenoid is in the energized state always, not only reduce the useful life of solenoid like this, the temperature of solenoid remains on higher level always, cause solenoid aging speed to be exceedingly fast, have a strong impact on adhesive dynamics and the closing speed of electromagnet.Therefore contactor electromagnet coil burnout situation is also more common.
Have again be exactly iron core in closing course, overcome the resistance of back-moving spring, so just cause the reduction of iron core closing speed, when in use, contactor is generally in closed state long-term, causes damping spring, under tripping spring is in energy storage state for a long time.By the physical characteristic of spring, can show that contactor is after operation a period of time, time of its opening velocity upper and prevent closed spring performance on worse and worse.So, often there will be contactor point/close load time contact burnt/burn.The coil blackout when discharging, automatically reset by back-moving spring, opening speed reduces greatly, also very easily produces contact arc discharge phenomenon, makes the life-span of upper and lower contact also greatly reduce like this.
Also have a kind of energy-saving electrical magnetic mechanism to be generally that magnetic keeps, this kind of electromagnetic mechanism is coil energization, keeps attracting state by permanent magnet, the coil blackout when hold mode, and runs in low-power consumption electricity consumption situation.In attracting process, the resistance of back-moving spring to be overcome equally, reduce the closing speed of iron core, make contact easily produce phenomenon of arc discharge equally in closing course, the life-span of upper and lower contact is also reduced greatly.
Summary of the invention:
