产品特点与应用
Purpose The mining flameproof and intrinsically safe vacuum electromagnetic starter is suitable for use in underground coal mines with explosive risk, where methane gas mixtures may be present. The starter is used in AC 50Hz power supply systems with voltages up to 1140V and rated currents up to 400A, to control the starting, stopping, and reversing (during shutdown) of three‑phase AC asynchronous motors driving mining machinery and equipment. It enables control functions such as local control, remote control, and automatic drainage, while providing protection for the motors and supply circuits. When networked, it can be integrated into mine monitoring and control systems to achieve automated control of power supply equipment.
Product Features
-
Adopts a quick‑opening door structure and a drawer‑type frame chassis, offering a compact design that facilitates easy inspection and maintenance.
-
The starter's protective device incorporates an advanced microprocessor, providing high protection accuracy and fast response. The modular structure simplifies operation and maintenance.
-
Equipped with a 128×64 LCD display and a menu‑driven human‑machine interface, the starter offers intuitive and convenient operation. It can display real‑time parameters such as system voltage, three‑phase current, and equipment status, as well as fault type, fault parameters, and fault occurrence time.
-
All protection parameters can be adjusted via the menu. The starter features multiple protection functions including overload, short‑circuit, earth leakage lockout, undervoltage, phase loss, three‑phase imbalance, and overvoltage absorption. It offers a wide application range and high protection accuracy.
-
Equipped with fault memory and query functions. All protection parameters after each adjustment are stored in memory and automatically retrieved upon next power‑on or system reset. The protector also stores fault information, including the specific time of fault occurrence, for later query.
-
The menu operation keys on the protector allow convenient access to functions such as protection setting modification, protection testing, information query, and operating mode selection.
-
Equipped with an intrinsically safe RS‑485 communication interface for easy remote monitoring and control.
-
The intrinsically safe maintenance‑free version has all control and acquisition circuit interfaces within the controller designed as intrinsically safe.
-
The intrinsically safe keyboard allows convenient access to functions such as setting modification, protection testing, information query, and operating mode selection.
-
The starter features an intrinsically safe remote control function, which reliably prevents false starts caused by short‑circuiting due to cut remote control cables.
