Product Overview

The integrated solution for high-voltage frequency conversion control and drive of internal mixer is a solution provided by Shiyi Electric and Jiangsu Aerospace Power for the rubber and plastic industry's internal mixer equipment. By integrating Shiyi Electric's high-voltage frequency conversion technology with Jiangsu Aerospace's high-voltage motor and permanent magnet motor technology, the strong combination not only provides cost-effective and controllable supporting equipment for traditional 270/370 and other commonly used series of internal mixers, Provide strong equipment support and technical support for the development of permanent magnet motors in the rubber and plastic industry.

The CY-GP series intelligent high-voltage variable frequency speed control system adopts power unit series multi-level technology, directly outputting 6KV and 10KV voltages, and is a high high voltage source type frequency converter. The company's design goal is high reliability, easy operation, and high performance, to meet the urgent needs of users for speed regulation, energy-saving, and improved production processes of internal mixer equipment; In order to minimize the construction period of installation and renovation of the high-voltage variable frequency speed regulation system, the system adopts an integrated design concept, including all components and internal wiring such as transformer cabinet, power cabinet, control cabinet, (high-voltage switch cabinet or bypass cabinet optional). Users only need to connect high-voltage input, high-voltage output, low-voltage control power supply, and control signal line.

In order to meet the needs of renovation projects and reduce the investment in new projects, each functional component of the CY-GP 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 encounter accidents during transportation and installation.

The T (B) YCP series high-voltage frequency converter starting (flameproof) three-phase permanent magnet synchronous motor and the TYCX series high-voltage high-efficiency three-phase self starting permanent magnet synchronous motor are two permanent magnet motors designed and developed by Jiangsu Aerospace in the rubber and plastic industry, which have a similar structure and spectrum to traditional asynchronous motors and can directly replace traditional high-voltage asynchronous motors.
