TNS Fully Automatic AC Voltage Stabilizer

The Yibaling TNS series of fully automatic AC voltage regulators is a high-performance three-phase power protection device specifically designed for industrial and critical facilities. It employs advanced modular windings and intelligent phase-by-phase regulation technology. It can monitor and automatically correct fluctuations, imbalance, and under-voltage/over-voltage issues in three-phase voltages in real time, and output continuous and stable pure power.

Product Applications

In practical applications, the TNS fully automatic AC voltage stabilizer plays the role of the guardian of the industrial heart.

1. Precision Processing Workshop

When a large CNC punch press starts up and causes a sudden drop in grid voltage, the TNS series voltage stabilizer can quickly compensate within tens of milliseconds, ensuring that the servo motors of the adjacent five-axis machining center do not shake, thereby avoiding the scrapping of tens of thousands of precision parts due to size deviations.

2. Power Distribution Room of a Commercial Complex

Due to the uneven power consumption periods of each floor's shops, the three-phase load is severely unbalanced. Traditional voltage regulators may be overwhelmed, while the intelligent phase-by-phase regulation function of this product can independently and precisely stabilize each phase voltage, fundamentally eliminating the problems of neutral line overload heating and flickering caused by voltage imbalance, and ensuring the smooth operation of the air conditioning, lighting, and elevator systems of the entire shopping mall.

3. Sewage Treatment Plants in Remote Areas

In these places, the voltage at the end of the long-distance power supply line often hovers around 300V at a low level. The wide-range voltage regulation capability of the TNS fully automatic AC voltage regulator can steadily raise it to the standard 380V, ensuring that key power equipment such as blowers and lift pumps receive sufficient torque, and avoiding equipment start-stop failures and reduction in sewage treatment efficiency due to insufficient power.

Product Information

Core Material

The core material system of the Yibaling TNS fully automatic AC voltage stabilizer forms the physical basis for achieving industrial-level stable power supply. It is built around three main goals: efficient voltage regulation, intelligent control, and robust protection.
A reliable TNS voltage stabilizer is essentially a system engineering integration of high-grade silicon steel, high-conductivity copper materials, wear-resistant composite materials, semiconductor devices, and protective materials.
The core lies in using cold-rolled silicon steel sheets with high magnetic permeability and low loss as the core, combined with high-purity electrolytic copper enameled windings, to construct an efficient and low thermal loss magnetic-electric conversion main body.
The key voltage regulation action relies on the precise sliding of special metal graphite composite carbon brushes on the windings. This material has excellent conductivity, self-lubrication, and wear resistance properties.
Higher-end models use thyristors or IGBT power semiconductor modules to achieve contactless, millisecond-level, spark-free switching, with extremely long service life.
The product's brain consists of industrial-grade microprocessors (MCU) and precise voltage/current transformers, responsible for real-time precise sampling and rapid decision-making.
In terms of safety and structure, the internal high-current channels use low-impedance tin-plated copper bars, the chassis is made of high-quality cold-rolled steel plates after rust-proof treatment, and integrated metal oxide varistor (MOV) and other components form an anti-surge protection circuit.

The Customization of TNS Fully Automatic AC Voltage Stabilizer

1. Key parameters and technology confirmation

Core performance indicators:

Stabilization accuracy: Clearly specify whether it is ±1% or ±0.5%, as this directly affects the accuracy level (such as 0.2 class) of the internal sampling circuit (such as 16-bit or higher precision ADC chip) and the voltage transformer (PT).
Response time: Clearly specify whether it is the full response time (from voltage fluctuation to recovery within the accuracy range) or the step response time. For scenarios such as press machines and spot welding machines, it is necessary to confirm the requirement for instantaneous voltage sag compensation speed, which determines whether to adopt a contactless (thyristor) switching or a high-speed servo motor solution.

Initial framing of key materials and processes:

Based on efficiency requirements, clearly specify the upper limit of the silicon steel sheet grade, for example: "Must use Nippon Steel 27ZH100 or a domestic grade 30QG120 or above of oriented silicon steel sheet".
Based on overload capacity and lifespan requirements, clearly specify the type of voltage regulation component: "In scenarios requiring frequent adjustment and maintenance-free, specify the use of an Infineon or equivalent brand bidirectional thyristor (thyristor) module; in high impact load scenarios, specify the use of silver graphite composite carbon brushes and special wear-resistant windings with servo motor solution".
Based on the environment, clearly specify the protection and anti-corrosion process: "For outdoor coastal environments, the box body uses 304 stainless steel material, or the carbon steel box body uses the 'epoxy zinc-rich primer + epoxy iron oxide intermediate paint + polyurethane topcoat' heavy anti-corrosion coating system, with a dry film total thickness of ≥ 250 μm."

2. Scheme design

Electromagnetic and structural deepening design:

Electromagnetic calculation document: Provide detailed calculations, including iron core magnetic flux density value (such as ≤ 1.65T), electric flux density value, short-circuit impedance calculation, loss distribution (no-load loss, load loss, additional loss) etc.

Key design outputs:

Compensation transformer design drawing: Clearly specify its capacity, voltage ratio, winding form (such as foil winding or wire winding), insulation grade (such as H class 180°C).
Voltage regulator/power module selection calculation: If using contactless type, provide the voltage/current safety margin calculation (usually voltage ≥ 2.5 times, current ≥ 2 times) and heat dissipation calculation.
Control logic diagram: Clearly specify the hardware circuit for independent three-phase sampling, control algorithm (such as fuzzy PID), protection logic (such as overcurrent inverse time characteristic curve).

3. Purchase of raw materials and production start

Core material procurement and warehousing inspection:

Silicon steel sheet: Verify the supplier's quality certificate and sample for iron loss value (P1.7/50) and magnetic induction strength (B800).
Electromagnetic wire/copper foil: Verify the conductor's DC resistance rate, insulation layer thickness and withstand voltage value.
Power semiconductor module: Verify the original factory report and conduct static parameter tests (such as trigger voltage, current).
Insulation material: Verify the heat resistance grade certification and thickness uniformity.

Key processes and special process control:

Iron core stacking: Use stepped stacking tooling, control the stacking coefficient (> 0.96), and measure the no-load current and initial loss value after completion.
Winding winding and insulation treatment: Use constant tension winding machine, and conduct inter-winding pulse withstand voltage test (such as 3.5kV, 0.1s) after completion. For impregnation process, record the "preheating-vacuum-immersion-curing" entire temperature-pressure curve process.
Contactless power unit assembly: Apply the specified type of thermal conductive silicone grease on the heat sink, use a torque wrench with a fixed torque to tighten the installation bolts, ensure consistent contact thermal resistance.
