Product Detail

Product Introduction

The 32-Step Voltage Regulator is a fully automated, maintenance-free voltage regulator for distribution lines. This voltage regulator is designed to improve the voltage quality of the 10 kV to 35 kV distribution network, ensure that the line voltage meets the requirements, and continuously monitor the load-side voltage via a microprocessor and automatically change the voltage level to control the line voltage within the target range.

Core features

  • 32-Level Precision Regulation: Enables on-load automatic voltage adjustment with high accuracy, each step fine-tuning voltage by 0.625% for a ±10% total range.
  • Arc-Free Tap Design: Unique voltage regulating tap structure eliminates arcing during operation, extending service life to nearly 1 million cycles.
  • Fully Sealed & Maintenance-Free: IP-rated fully sealed design ensures superior weather resistance, requiring zero maintenance for reliable outdoor/indoor use.
  • Flexible Operation & Integration: Allows on/off switching of voltage regulation as needed; directly integrates with SCADA systems for seamless power distribution automation.
  • Energy-Efficient Single-Phase Design: Reduces core loss and no-load loss significantly, optimizing energy efficiency for low-carbon operations.
  • Enhanced Grid Performance: Minimizes line losses, stabilizes voltage fluctuations, and prolongs the service life of connected electrical equipment.

What aspects need attention during the installation of dry-type transformers?
What aspects need attention during the installation of dry-type transformers?
1 Pre - installation PreparationAs a front - line installer, I know very well that the preparation work before installing a dry - type transformer must be thorough. First, I will carefully review the design drawings and technical documents, and check one by one the technical parameters such as the model specification, rated capacity, and voltage level of the transformer to ensure they are in full compliance with the design requirements. Then, I will conduct an unpacking inspection of the transfo

What are the causes of dry-type transformers burning out during operation?
What are the causes of dry-type transformers burning out during operation?
1 Fault PhenomenonI am engaged in front - line fault maintenance work, and recently encountered problems with dry - type transformers. Dry - type transformers have a simple structure, are convenient for transportation, and easy for maintenance. They are widely used in power distribution places with relatively high environmental protection requirements. Because of their good fire - resistance, they can be installed in load - center areas to reduce voltage loss and power loss.The property manageme

Method for Automatic Isolation of Customer Equipment Faults by Load Switches in Distribution Networks
1 OverviewDistribution network safety has long been under - addressed, with its automation lagging substation automation . Using 10 kV intervals of existing substations to set line section points meets future grid needs . Configuration of distribution switches, section switches, and protection must match substation outgoing - line protection for reliability.

A Novel Detection Method for Stuck Faults in Load Switches
In recent years, as distribution automation advances, load switches see wider use in distribution lines. Yet, mechanical - failure - induced accidents are on the rise, burdening line operation and maintenance.Poor mechanical performance is the main cause of switch faults. Many scholars study large - scale switchgear operation, using methods like coil current detection, vibration signal analysis, switch travel testing, ultrasonic flaw detection, and infrared thermometry. Motor - current - based s
