Three-phase asynchronous motors should be stored in a dry, ventilated warehouse. The appropriate temperature in the warehouse should be maintained at5℃～35℃Within the range, the relative humidity is not higher than65%Harmful gases, steam and smoke and dust should be prevented from invading.

       Second, strictly prevent insects, rats and other bites of organic insulation materials.

       Every six months, the motor in long-term storage should be inspected once, and the insulation resistance should be measured once, if there is a significant reduction in dry treatment.

       4. Management requirements for the standby server

       1.Do maintenance work such as anti-freezing, anti-condensation, heat preservation, anti-corrosion, lubrication, turning, electrical insulation testing, cleaning, etc., to ensure backupThree-phase asynchronous motorIn good condition, guaranteed to be ready for operation. Keep a record of the problems and make a handover.

       Check the good condition of the spare motor regularly, and the high humidity storage point (that is, the relative humidity is greater than65%Above) should be checked once every month; Low-humidity storage points are inspected every six months, and dry storage points are inspected once a year. Check contents:

       aInsulation resistance measurement: rated voltage＜1000V,The insulation resistance is not less than normal temperature0.5Megohm; Rated voltage>1000VThe insulation resistance at room temperature is not less than per thousand volts1Megohm;

       bMeasurement of absorption ratio of motor insulation resistance: the absorption ratio is not less than1.3;

       cManual turning check: check the lubrication of the bearing and whether there are friction problems.

       2.Periodic turning system of spare motor

       According to the actual situation, the spare motor turning cycle is classified and formulated. For the spare motor with interlock self-starting, the turning operation must be carried out under the premise of ensuring production and personal safety, and each time shall not be less than one and a half cycles. The exposed part of the equipment should be rotated(Such as shaft head, coupling, etc)Clear turning marks are marked and correspond to the turning cycle. Motor turning records should be established.
