Product Description
Product Overview
The RNHV series intelligent high-voltage variable frequency speed control device adopts power unit series connection technology, directly outputting 6kV/10kV voltage, and belongs to the high voltage source type frequency converter.
The product is designed with the goal of high reliability, easy operation, and high performance, meeting the needs of users for speed regulation, energy-saving, and improved production processes of fans, pumps, and compressors.The entire system has undergone strict inspection and performance testing before leaving the factory, ensuring the quality and performance of each factory equipment.
In order to meet the needs of renovation projects and reduce investment in new projects, and to minimize the installation and renovation construction cycle of high-voltage variable frequency speed regulation devices, the system adopts an integrated design concept, including all components and internal wiring such as transformer cabinets, power cabinets, control cabinets, high-voltage switchgear (optional bypass cabinets). Users only need to connect high-voltage input and output cables, low-voltage control power supply, and control signal wires.
The RNHV series high-voltage variable frequency speed regulation device has the characteristics of integrated transportation and unilateral maintenance, making on-site installation, maintenance, and debugging convenient and easy to use; The unit DC support capacitor needs metallized film capacitor and built-in mechanical bypass module. Compared with Electrolytic capacitor, it has the characteristics of high reliability, maintenance free and long service life, perfect protection and control functions, making the product more suitable for the environment and meeting the process speed regulation requirements under various working conditions.
