High-Voltage Solid-State Soft Starter
Product Overview
The high-voltage solid-state soft starter (hereinafter referred to as the soft starter) is a high-voltage motor soft starter designed with the latest concepts. It is mainly used for the control and protection of start and stop of squirrel-cage asynchronous and synchronous motors. The device is composed of multiple thyristors connected in series and parallel to meet different current and voltage requirements.
Application Fields
The product is widely used in industries with a rated voltage of 3000-10000V, including electric power, building materials, chemical engineering, metallurgy and steel, papermaking and so on. It can be well matched with various electromechanical equipment such as water pumps, fans, compressors, crushers, mixers and belt conveyors, serving as ideal starting and protection equipment for high-voltage motors.
Technical Features
Maintenance-free: Thyristors are non-contact electronic components. Unlike other types of products that require frequent maintenance of liquids and parts, they convert mechanical service life into the service life of electronic components, and can run continuously for years without shutdown maintenance.
Simple installation and operation: Only power cables and motor cables need to be connected during installation to put it into operation. Before high-voltage operation, low voltage can be used to conduct electrical tests on the whole system.
Backup function: A vacuum contactor capable of directly starting the motor is installed inside the device. In case of faults, the vacuum contactor can be used to start the motor directly to ensure continuous production.
The main circuit components are high-voltage thyristors, equipped with voltage sharing protection and overvoltage protection systems. An electromagnetic interlock device is installed to prevent personnel from entering the high-voltage device when it is electrified.
Adopts advanced optical fiber transmission technology to realize isolation between trigger detection of high-voltage thyristors and the low-voltage control circuit. A 32-bit ARM core microcontroller is adopted for central control, featuring real-time, efficient, intuitive control, high reliability and good stability.
Chinese/English LCD/touch screen display system with humanized operation interface.
Equipped with RS-485 communication interface, it can communicate with upper computers or centralized control centers.
All circuit boards have passed strict aging tests.
