98 Overload protection_ overload device

Category: Overload protection
Product Introduction:Overload protection
Order Hotline:0769-83811196
    Overload protection by sensing temperature and current to protect the compressor. Overload is basically composed of a normally closed contact and bimetallic element. Overload protection is assembled outside of the compressor, and direct contact with the compressor housing and compressor windings connected in series. If the compressor does not start for some reason, the overload stall current will cause rapid heat the bimetal element bent, cause rapid jump, cut off the current flowing through the compressor to protect the compressor. Similarly, if the compressor motor winding temperature compressor cause abnormal heat is too high, the protector will heat and jump, so as to protect the compressor. As long as the cause of the malfunction does not exclude, in the case of compressor overload, again and again with the action of the bimetal element and open stop.
    Use ohmmeter for testing
    1. If the overload protection device is disconnected, then let it cool to room temperature (closed) continue to measure.
    2. Although capable of continuous observation of work overload, however, to confirm that the parts are there hard work according to specifications.
    3. If you are not sure whether there is a problem overload, replace parts of the same
