24кВ Однофазный опорный 32-ступенчатый автоматический регулятор напряжения

The RVR-1 voltage regulator achieves automatic on-load voltage regulation by adjusting the transformer ratio through the on-load tap changer. The intelligent controller RVR samples, analyzes, judges, and processes the voltage on the line, then sends signals to drive the on-load tap changer to adjust the voltage.

The RVR-1 voltage regulator is equipped with self-protection lockout functions, including line fault, overload, overcurrent, and undervoltage protection. The RVR-1 voltage regulator also features a unique on-load tap changer design that prevents arcing during voltage regulation, ensuring a service life of up to two million operations. The RVR-1 voltage regulator features a fully sealed design, with a high level of protection and excellent weather resistance, allowing for long-term maintenancefree operation. 

Advantages of the product 

• High precision: Within the set voltage regulator range, it automatically adjusts the voltage in 32 loaded steps.

• Long service life: The unique voltage-tapping switch design prevents arcing during voltage adjustment, ensuring a mechanical operational lifespan of 1 million cycles.

• Low maintenance: Fully sealed design with high protection rating, excellent weather resistance, allowing for long-term maintenance-free operation, with a design life of 20 years.

• Low loss: The single-phase design can minimize iron losses and reduce no-load losses, with total losses being less than 0.1%.

• Strong overload capability: Designed with a rated capacity for a 55°C temperature rise, it can handle an overload of 12% at a 65°C temperature rise.
