Complaint
The whole system is divided into two parts, the first part: the front-end power supply part; the second part: the measurement control part. For the power range of the motor under test: 110KW; power type: AC three-phase; voltage level: AC 380V/220V, etc., the system adopts industrial computer and digital signal processing unit, which integrates resistance, insulation, withstand voltage, turn-to-turn, no-load and many other measuring equipment. It has the advantages of high speed, high precision, strong stability, and convenient use. It is a comprehensive testing equipment for intelligent motors.
1. Winding DC low resistance measurement (U phase, V phase, W phase)
a) Range 0~2000.00Ω
b) Automatic temperature compensation, the program converts the resistance value according to the set temperature value according to the temperature rise formula (default 20ºC)
c) Test method: four-terminal method
2. Withstand voltage test
a) Test voltage: AC 0~5000V
b) Leakage current: 0~100mA
c) Test time: 1~99S (set arbitrarily in the software)
3. Inter-turn insulation impulse withstand voltage test
a) Test peak voltage: AC 100~5000V (set arbitrarily in the software)
b) Detection and judgment mode: the image and data simultaneously show the difference of the waveform area and the poor waveform area
4. Insulation performance test
a) Test voltage: DC 500V/1000V
b) Test range: 0~500MΩ
c) Test time: 1~99S (set arbitrarily in the software)
5. No-load test (factory-specific items)
a) Test voltage: AC 0-500V
b) Test current: AC 0-40A
c) Test power
