8000kvA/13.2 INDUCTION VOLTAGE REGULATOR

Technical characteristics

Ø regulator can smooth ,stepless and  continuous adjusting and output voltage

Ø Transmission motor adopts three-phase ac asynchronous motor

Ø Regulator wave-shape distortion ratio:

² When input voltage of regulator are rated value and its wave shape are sine wave, and when regulator no - loading output voltage be between 5% to 25% range, its wave shape distortion rate will be less than 10%;

² When this voltage will be more than 25%,its wave shape distortion rate will be less than 5%.

Ø Output voltage asymmetry degree: When voltage regulator three-phase input voltage symmetry and under rated conditions, the maximum asymmetry degree of three-phase no-load output voltage of should be less than 1%

Ø   Overload ratio: (gradually loading increase )

Ø Power frequency withstand voltage of winding to grounding : 24KV/1min

Ø Temperature rising: under the rated loading, based on workshop temperature, the winding temperature rising will be 65K,, the oil surface temperature rising will be 55K.

Ø Regulating time: 70S

Ø Provided with temperature indicating controller, moisture absorber.

Ø The up and down limit switch will be provided for limit position of up and down.(one is normally open and the other one is normally close).

Ø Transformer oil: 25# transformer oil.( the oil will be prepared by customer).

Ø The core of regulator will be B50A470 No trend of cold rolled silicon steel sheet made in Shanghai Boosteel.

Ø The wire will be Winding epoxy impregnating copper flat wire of one layer of self adhesive double glass-fiber covered polyester film. The insulation material of wire is polypropylene film.

Ø The equipment colour: gray.

Ø factory inspection: Dc resistance test, insulation resistance test, power frequency withstand voltage test, the coil interturn test (winding to winding) , no load test (measurement no-load loss, no-load current, output voltage range, phase sequence), short circuit test (measuring impedance voltage, short circuit loss). 

Ø In addition to the above technical characteristics, and the others are accord with the China machinery industry standard JB/T8749.1 and JB/T10093.
