Insulation grade division of vortex fan
source:Industry News release time:2021-07-13 Article author:Rosit Popular:Air band saw
In electrical equipment such as generators, insulating materials are the weakest link. Insulating materials are particularly susceptible to accelerated aging and damage due to high temperatures. Different insulating materials have different heat resistance, and electrical equipment using different insulating materials has different ability to withstand high temperatures. Therefore, general electrical equipment stipulates the maximum temperature of its work.
Nassid vortex fan, motor and pump body are all produced by ourselves, using class F insulated motor. The following is the relationship between the levels.
The insulation grade of the motor refers to the heat resistance grade of the insulating material used, divided into A, E, B, F, and H grades. The allowable temperature rise refers to the limit of the increase in the temperature of the motor compared to the ambient temperature.
Insulation temperature class A class E class B class F class H class
Maximum allowable temperature (℃) 105 120 130 155 180
Winding temperature rise limit (K) 60 75 80 100 125
Performance reference temperature (℃) 80 95 100 120 145
According to the ability of different insulating materials to withstand high temperatures, seven allowable maximum temperatures are specified for them, which are arranged according to the temperature: Y, A, E, B, F, H, and C. Their allowable operating temperatures are respectively: 90, 105, 120, 130, 155, 180 and above 180°C. Therefore, Class B insulation indicates that the insulation heat resistance temperature used by the generator is 130°C. When the generator is working, the user should ensure that the insulating material of the generator does not exceed this temperature in order to ensure the normal operation of the generator.
