Regulation of motor starting times and interval time

A. Under normal circumstances, the squirrel cage motor is allowed to start twice in the cold state, and the interval of each time shall not be less than 5 minutes. In the hot state, it is allowed to start once;Whether in cold or hot state, the motor should find out the reason after starting failure to determine whether to start the next time.
B. In case of accident (to avoid shutdown, limit load or cause harm to the main equipment), the motor can be started twice continuously regardless of the number of cold and hot states;For motors below 40KW, the starting times are not limited.
C. Under normal circumstances, the starting times of the DC motor should not be too frequent, and the starting interval time should not be less than 10 minutes when the low oil pressure test is conducted.
D. In the event of an accident, the starting number and time interval of the DC motor are not restricted.
E. When the motor (including DC motor) is in motion balance test, the starting time interval is:
(1). Motor below 200KW (all 380V motor, 220V DC motor), the time interval is 0.5 hours.
(2) 200-500KW motor, the time interval is 1 hour.
Includes: condensate pump, congealing pump, front pump, shore pump, furnace circulating pump, #3 belt conveyor, #6 belt conveyor.
(3). For motors above 500KW, the time interval is 2 hours.
Includes: electric pump, coal crusher, coal mill, air blower, primary fan, suction fan, circulating pump, heat network circulating pump.
