YA811 epoxy fast drying impregnated insulating paint transfo

 In general, the insulation resistance of the motor is measured in megger, and the insulation resistance between each two-phase winding and each phase winding and case is measured to determine whether the insulation performance of the motor is good or bad.

  When the insulation resistance is measured using a megger, the motor at 500 volts or less is normally measured with a 500 volt megger, and the motor at 500-1000 volts is measured with a 1000 volt megger. Motors with voltages above 1000 volts are measured with a 2500 volt megger.

  Motor in the thermal state (75 ≧) conditions, the general small and medium-sized low-voltage motor insulation resistance should not be less than 0.5 megohm, high-voltage motor per kilovolt operating voltage winding rotor winding insulation resistance, the minimum shall not be less than 0.5 megohm ; Motor secondary circuit insulation resistance should not be less than 1 megohm.

  Motor insulation resistance measurement steps are as follows:

1、Product composition and characteristics

YA811 paint is composed of epoxy resin, curing agent, thinner and other components of the two-component impregnated insulating paint. Composition ratio of 1: 1, heat-resistant grade B (130). YA811 paint with good impregnation, curing temperature is low, fast drying, film tough, bright, excellent insulation properties, moisture and other characteristics.

 

2、use

It is suitable for fast drying or continuous immersion of small motor coil and electrical coil, such as air conditioner motor, fan motor, water pump motor, power tool motor (stator), small transformer, etc., suitable for closed small motor.

 

3、Process parameters

Pre-bake tide: 80 ~ 110 ≧ bake for 1 hour。
Impregnation: The workpiece is cooled to below 60 ° C, immersed in the paint tank for 2 to 15 minutes until there is no bubble。
Drop paint: room temperature drop paint 30 to 60 minutes.
∠Curing conditions: the workpiece into the cold oven, the oven gently heated to the curing temperature, according to the table time insulation, drying up.

 

4、Precautions

Insulating paint for flammable and explosive materials, should pay attention to safety before use. Dip paint the workpiece baking, the oven to stay out of the exhaust channel, in the process of warming oven door can open a seam, insulation can not be locked. Try to use no open flame heating source.

 

5、Special Note

The company strictly in accordance with the relevant product standards to control product quality. Due to the diversity of application conditions and variability and many other factors, it does not rule out the need for user self-test study, the law does not guarantee that some of the performance of a particular product for a specific use, and retain the data to modify the power.

 

6、Technical Parameters

  Disconnect the 6 ends of the motor terminal box.

  Megou flattened, not wiring first, shake the megger. Should be pointed to the "∞", then the table "I" (line) and "e" (ground) of the two terminals with a cable clip clip short, slowly shake the handle, the needle should point to "0" At the office.

  Measure the resistance between the three-phase windings of the motor. The test clamps are connected to either end of any two-phase windings, respectively, and the table is stabilized by reading the meter clock at a speed of 120 revolutions per minute.

  In the same way, the insulation resistance of each phase is measured in turn. However, it should be noted that the table labeled "e" or "ground" of the terminal, should be connected to the chassis without insulation.
