II. Core Technology Principles and Structural Design

1. Principles of Intelligent Control

High-voltage squirrel-cage motor starter cabinetHigh-Performance Programmable Logic Controller (PLC) 或Microprocessor SystemCore Control UnitthroughTemperature Characteristics of Liquid Resistors或Thyristor Phase-Shift ControlPrinciple: Achieving precise control over the motor start-up process 。

Liquid Resistance Starting PrincipleBy utilizing an electrolyte with negative temperature characteristics as the resistive medium, the temperature of the resistive element gradually increases during motor startup while its resistance value progressively decreases. This causes the terminal voltage to rise incrementally, leading to a gradual increase in starting torque. This achieves smooth motor startup while reducing the starting current.
Principle of Solid-State Soft Start: Employing multiple thyristors in series and parallel configurationsBy controlling the variation of the trigger angle, the conduction level of the thyristor is adjusted, thereby precisely regulating the input voltage to the motor and achieving a smooth starting effect.

2. Precision Structural Design and Safety Features

Modular Component DesignIncludes components such as resistors, high-voltage soft-start control cabinets, isolation cabinets, switching cabinets, and star-point control cabinets, supplied as a complete set for convenient installation and maintenance.
Multi-layered protection mechanismProvides comprehensive protection for the motor against overload, phase failure, and short circuits, ensuring a safe and reliable starting process.
