High Voltage Electric Motor voltage above 1000V. Commonly used is 6300V and 10000V. The motor power is proportional to the product of voltage and current, so the low-voltage motor power increases to a certain extent (eg, 300KW / 380V). The current is limited by the allowable capacity of the wire, or the cost is too high. Need to improve the voltage to achieve high-power output.
High Voltage Electric Motor Advantages are: power, bear the impact of strong; current is small.
1, High Voltage Electric Motor is generally designed at an altitude of not more than 1000m, ambient air temperature does not exceed 40 ℃ place to run.
2, High Voltage Electric Motor within ± 5% of the additional voltage changes, the rate can be continuous operation. If the voltage fluctuates by more than ± 5%, the load should be limited according to the manufacturer's specifications or test results.
3, the operation of the High Voltage Electric Motor temperature should be in accordance with the provisions of the manufacturer, the lack of this phase of information.
4, for short-term fixed High Voltage Electric Motor, the temperature limit of its various parts of the value specified in Table 1-2 to increase the value of 10K.
5, the sliding bearing allowable temperature of 80 ℃ (oil temperature is not higher than 65 ℃). Rolling bearing allowable temperature of 95 ℃ (ambient temperature does not exceed 40 ℃).
6, such as High Voltage Electric Motor running the maximum ambient temperature between 40 ℃ to 60 ℃, the temperature limit specified in the table should be less than the ambient temperature of more than 40 ℃ value.
7, such as High Voltage Electric Motor running ambient temperature between 0 ℃ to 40 ℃, the temperature limit is generally not increased. After obtaining an agreement with the manufacturer, it is allowed to increase (40-t) K, but up to 30K.
8, from the outdoor total to the cooling air of the motor, in order to avoid damp, after the shutdown, you must promptly stop the supply of cooling air.
9, check the spark under the spark is normal, collecting ring (or steering) whether there is burns and wear.
10, check the motor running in the abnormal noise and vibration, whether the stator and rotor friction.
