28 1K and 288K are two different temperature grades of the stationary rotor. Static combustion plate is a key component used in explosion-proof equipment, which is used to control and limit the temperature inside electrical equipment to prevent explosion caused by sparks.

The differences are as follows:

1. Temperature grade: 28 1K and 288K respectively represent two different temperature grades. 28 1K means that the maximum allowable surface temperature of the static combustion plate is 28 1 c, and 288K means that the maximum allowable surface temperature is 288 c. Therefore, their temperature grades are different.

2. Scope of application: Due to different temperature grades, 28 1K and 288K static combustion blades are suitable for different application scenarios. The specific application scenarios need to be determined according to the actual needs and environmental conditions.

3. Safety performance: Due to different temperature grades, the static combustion blades of 28 1K and 288K have different safety performance. A lower temperature class means a lower maximum allowable surface temperature, thus providing higher safety performance.

It should be noted that the selection of the appropriate temperature grade of the stationary rotor should be determined according to the specific application requirements and environmental conditions to ensure the safe operation of the equipment. It is recommended to consult professionals or refer to relevant standards and specifications when selecting and using static combustion tablets.
