The utility model has advantages of the simple structure, the three-phase automatic balance, the free carbon brush friction, etc.
Description
The utility model relates to a kind of high-power electric voltage stabilizer, is meant a kind of high-power no wear-compensating formula electric power voltage stabilizer especially.
At present, what we often saw is servo-type compensation high-power electric voltage stabilizer, and it exists many defectives, as: the high-power brush wear of servo-type needs seriously to safeguard that the mechanical fault of motor is many that pressure regulation speed is slow, complicated in mechanical structure etc.
In order to overcome the defective that above-mentioned voltage stabilizer exists, the utility model provides a kind of high-power no wear-compensating formula electric power voltage stabilizer, and it is simple in structure, non-carbonate wearing and tearing, and pressure regulation speed is fast.
For achieving the above object, the solution that the utility model is taked is: a kind of high-power no wear-compensating formula electric power voltage stabilizer, comprise the sampling transformer, mutual inductor, compensator transformer, relay, transistor, major loop and major loop relay, contactor, it is characterized in that compensator transformer respectively has a cover auxiliary body, corresponding auxiliary body is made of corresponding two relays, the secondary coil of compensator transformer is that compensating coil is series at major loop, the moving contact of one relay termination of the primary coil of compensator transformer, the moving contact of another relay termination, the primary coil and the relay of compensator transformer have been formed phase-adjusting circuit.
Because the utility model has been concentrated many groups winding combined compensation mode, and adopted the sampling transformer, adopt the compensation high-power electric voltage stabilizer of composition physical construction such as servomotor to compare with traditional SBW series, have advantages such as simple in structure, rapid dynamic response speed, three-phase self-poise, non-carbonate wearing and tearing, no mechanical fault.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
