Características y aplicaciones del producto
Mining flameproof and intrinsically safe multi‑circuit vacuum electromagnetic starters are suitable for use in underground coal mines with explosive risk, where methane gas mixtures may be present. Depending on actual requirements, the starter can be used to start, stop, and control various equipment on the coal mining face, including shearers, scraper conveyors, stage loaders, crushers, emulsion pump stations, belt conveyors, and others. It supports single‑machine two‑speed operation, two‑machine two‑speed operation, and sequence control, and can control up to fourteen circuits with different loads. At the same time, it provides comprehensive protection for all controlled load circuits, including overload, short‑circuit, phase loss, overvoltage/undervoltage, backup protection, and earth leakage lockout. When networked, it can be integrated into mine monitoring and control systems to achieve automated control of power supply equipment.
Product Features
The mining flameproof and intrinsically safe multi‑circuit vacuum electromagnetic starter is equipped with an imported PLC module and a protection device. The protector features an advanced microprocessor, high‑precision data processing, and state‑of‑the‑art protection algorithms, offering advantages such as high protection accuracy and fast response. The protector provides multiple protection functions including earth leakage lockout, overload, short‑circuit, three‑phase imbalance (including phase loss), undervoltage, and overvoltage. It integrates protection, control, setting, self‑diagnosis, and communication capabilities. Key advantages are as follows:
-
Adopts a vacuum isolating switch with built‑in circuit breaker functionality;
-
Features an integrated modular design, making replacement and maintenance exceptionally simple;
-
Equipped with a large‑screen color display, providing clear and rich visual information;
-
User‑friendly and intuitive operating system interface, easy for on‑site operation;
-
Flexible control modes: single‑unit control, multi‑unit sequence control, and multi‑unit high/low speed control can be freely selected;
-
Comprehensive protection functions, simple parameter setting, and a pop‑up fault memory screen.
