working principle
The stable transformer integrated machine consists of a three-phase compensation transformer TB, a three-phase voltage regulating transformer TUV voltage detection unit, servo motor control and transmission mechanism, contactor operation circuit, protection circuit, etc.
The primary winding of the voltage regulating transformer TUV is connected in a Y-shape to the output terminal of the voltage regulator, and the secondary winding is connected to the primary winding of the compensating transformer TB, which is connected in series in the main circuit.
The principle is that when the input voltage UAI of phase A increases by Δ UAI, the compensation voltage UAC also changes accordingly by Δ UAC, and UAC=- UAI, keeping the output voltage UA0 of phase A unchanged. Similarly, the same applies to phases B and C.
The voltage stabilization process of the integrated voltage regulator is as follows: based on the change of output voltage, the voltage detection unit samples, detects and outputs a signal to control the servo motor SM to rotate. Through the reduction mechanism and driven by the chain, the brush group on the voltage regulating transformer TUV slides (or rolls) to adjust the secondary voltage of the voltage regulating transformer, so as to change the polarity and magnitude of the compensation voltage, and achieve automatic stabilization of the output voltage within the allowable range of the voltage stabilization setting accuracy, thus achieving the purpose of automatic voltage stabilization.
1: Pre sales service process:
According to the actual situation, engineers will be dispatched to conduct a comprehensive investigation of the user's site when necessary. Based on a comprehensive understanding of the usage requirements, targeted communication plans, transportation plans, commissioning plans, engineering supervision plans, product maintenance plans will be formulated according to the actual situation
Quality feedback plan. These plans will be implemented after written confirmation from the user.
2: Testing phase process:
Dispatch engineering and technical personnel to the site for commissioning, and conduct a 24-hour trial run with load after commissioning. After the equipment runs smoothly, both parties shall sign and confirm before the engineering and technical personnel can evacuate the site. During this period, professional engineers will provide comprehensive supervision.
3: After sales service process and matters:
Establish a dedicated customer profile for the product, and provide a one-year warranty and lifetime maintenance for the products sold.
Received a service call with a response time of 2 hours, which means a service plan will be developed within 2 hours and implemented after approval by the user.
During the warranty period, parts that malfunction due to no device defects or manufacturing process issues will be replaced free of charge. For faults caused by improper customer operation, component costs and transportation and accommodation expenses will be charged as appropriate. Any replacement of components or other accessories that occur after the warranty period will only incur cost, transportation, and labor expenses.
