Single Phase High-power Voltage Regulator

Yibaling single phase high-power voltage regulator is essentially a power valve that can precisely adjust the alternating current voltage. It can smoothly and continuously adjust the incoming voltage to any value you need within the allowable power range of the equipment. You can rest assured to choose Yibaling as your manufacturer and supplier of this product.
For those industrial and research fields that require both high power and extremely high voltage control accuracy, the product becomes a very useful assistant.
Among them, the self-coupled type has a simple structure and low cost, but there is brush wear; while the non-contact type, although more expensive, has the advantages of rapid regulation and maintenance-free, and is more suitable for automation control requirements.
The core feature lies in being able to bear loads of tens to hundreds of kilowatts, achieving precise voltage regulation, and having built-in multiple protections such as overcurrent and overheating.
Our product is widely used in scenarios such as soft start of large equipment, temperature control of electric furnaces, lighting adjustment, product aging testing, and new energy equipment experiments, becoming an important equipment for achieving safe, stable, and controllable power supply in modern power systems.

Product Picture

Product Structure

The voltage regulation core of the Yibaling single phase high-power voltage regulator relies on a set of precise and robust electromechanical coordination system. The basic principle is to continuously and steplessly change the effective turns ratio between the primary and secondary sides by precisely altering the contact position of the special brush on the finely ground conductive surface of the cylindrical winding, thereby achieving smooth regulation of the output voltage.
The key lies in the design and implementation of the transmission mechanism: The system is powered by a dedicated low-speed, high-torque asynchronous motor as the driving source. Its output undergoes a first-stage reduction and self-locking through a high-strength alloy worm gear pair, ensuring smooth transmission, precise positioning, and reliable locking at any position, preventing runout due to vibration.
The compact structure of the entire transmission chain and the high torque amplification ratio ensure that even under high-power and high-current conditions, the brush and the winding surface can maintain a constant and suitable pressure, thereby achieving low contact resistance, low sparks, and long-life reliable voltage regulation. This system is the physical foundation for the manual or automatic precise voltage regulation of the single-phase high-power voltage regulator to be realized and operate stably.

Operating Conditions

When using a Yibaling single phase high-power voltage regulator, special attention must be paid to the operating environment. It must be installed in an indoor area that is well-ventilated, clean and dry.
The installation should be stable, and sufficient space should be left around to allow the heat to dissipate. When connecting the power supply, the input voltage and frequency must be exactly the same as those marked on the equipment's nameplate, and the connected load must not exceed the maximum capacity specified by the device.
During operation, the environment must not experience significant vibrations. The voltage regulator should be kept away from corrosive gases, conductive dust, open flames, high-temperature equipment, and flammable materials.
The operators should preferably have relevant professional knowledge. They should also pay close attention to whether the output voltage, current, and heat dissipation of the equipment are normal.
At regular intervals, it is necessary to clean the dust, check if the wiring is loose, and if it is an old type of voltage regulator with carbon brushes, also check the wear condition of the carbon brushes.
Only when all these details are properly handled can the single phase high-power voltage regulator operate stably and reliably, and precisely help you adjust the voltage.

Custom Process

1. Key parameter locking

Determine the basic parameters that the customer needs: rated capacity (KVA, sufficient margin should be reserved for the impact current, it is usually recommended to increase by 30%-50%); input voltage range, output voltage range and accuracy (such as 0-430V adjustable, with an accuracy of ±1%).
Performance requirements: response speed (for rapid fluctuating loads), voltage regulation method (manual, automatic servo motor drive, contactless electronic voltage regulation), efficiency requirements.
Structural and material requirements: shell material (steel plate, stainless steel), cooling method (self-cooling, forced air cooling), special processes (such as anti-corrosion paint treatment, shock-resistant design).

2. Output documents

Both parties jointly sign the Customized Technical Agreement for Single-Phase High-Power Voltage Regulator, which serves as the legal and technical basis. The agreement should include all the quantitative indicators, material specifications and acceptance standards.

3. Design scheme

Core design selection: Determine whether to adopt the column-type voltage regulation or circular-type voltage regulation structure; select brush material (such as silver-graphite alloy) and surface treatment process of winding conductive ring (such as silver plating, thick tin plating).
Transmission and drive design: If it is automatic voltage regulation, the selection and matching of servo motor and worm gear reduction mechanism need to be designed to ensure the smooth regulation and precise positioning of the single-phase high-power voltage regulator.

4. Production

Put the designed technical scheme into production.
