Product Information 10kV Automatic Line Voltage Regulator

I. Product Introduction

The 10 kV automatic linear voltage regulator is an outdoor intelligent voltage regulation device specifically designed to address key issues in the 10 kV distribution network, such as long-distance power supply, large load fluctuations, low terminal voltage, and uncertain voltage quality. As a key component in distribution network modernization, it is widely used in rural areas, mountainous regions, industrial parks, urban and rural outskirts, remote areas, and other unstable voltage scenarios, playing a significant role in ensuring power supply reliability, improving user experience, and reducing network losses.

The device has an integrated design, mainly consisting of a controltransformer housing, a vacuum switch with load, an intelligent measurement and control controller, an electric drive, a comprehensive protection system, an external sealed cabinet, and auxiliary electrical components. It can be installed and commissioned immediately without additional auxiliary equipment, with a short construction time and high flexibility.

The operating principle is as follows: the intelligent controller collects key parameters in real time, including input voltage, output voltage, load current, and power factor. Using a built-in intelligent algorithm, it automatically sends voltage adjustment commands to activate the load tap-changer. Voltage boosting and buck regulation are performed precisely without power interruptions, ensuring a stable, consistent voltage within the national permissible range (10 kV ±10%). This completely resolves issues such as undervoltage during peak hours, overvoltage during off-peak hours, and frequent voltage fluctuations.

The equipment is specifically optimized for harsh outdoor conditions with a fully sealed and highly protected design. It supports pole-mounted and floor-mounted installations without the need for a dedicated distribution room, significantly saving space and construction costs. It features fully automated operation, unmanned operation, easy maintenance, and a long service life.

It fully complies with GB/T 1094.1-2013, GB/T 1094.2-2013, and relevant power industry standards. It can be directly connected to existing 10 kV distribution lines without extensive reconstruction, while maintaining high compatibility. Compared with traditional voltage regulation equipment, it offers clear advantages in regulation accuracy, response speed, protection effectiveness, and operating and maintenance costs, providing the most cost-effective, straightforward, and efficient solution for voltage stability during distribution network reconstruction.
