RENLE/Reynolds intelligent high-voltage inverter governor RNHV series

Introduction: RNHV series intelligent high-voltage frequency conversion speed regulation system adopts power unit series connection technology, directly outputs 6KV, 10KV voltage, and is a high-high voltage source type inverter. The company takes high reliability, easy operation and high performance as the design goal to meet the urgent needs of users for speed regulation and energy saving of fans and pumps, and improvement of production technology; In order to shorten the construction period of the installation and transformation of the high-voltage variable frequency speed control system to the greatest extent, the system adopts the concept of integrated design, including transformer cabinet, power cabinet, control cabinet, (high-voltage switchgear or bypass cabinet optional) and other components and internal connections, users only need to connect high-voltage input, high-voltage output, low-voltage control power supply and control signal line. In the advanced production and management environment, the whole system has been tested as a whole before leaving the factory to ensure the quality and performance of each piece of equipment.

In order to meet the needs of the renovation project and reduce the investment of the new project, each functional component of the RNHV series high-voltage variable frequency speed regulation system can be installed step by step, ensuring that the high-voltage variable frequency speed regulation system will not have accidents during transportation and installation, convenient front and rear maintenance methods, flexible and diverse heat dissipation methods, high-performance important imported components, and advanced production technology greatly reduce the requirements of the high-voltage variable frequency speed regulation system on the site environment.
