GB/T 28556-2012
ActiveFlameproof and intrinsically safe controller with frequency converter for coalmine ventilation fan
煤矿通风机用隔爆兼本质安全型变频调速控制器
Application Summary AI generated
This standard specifies technical requirements, test methods, and safety parameters for flameproof and intrinsically safe controllers with frequency converters used in coal mine ventilation fans. It is applied in underground coal mining environments to ensure the controller can operate safely in explosive gas atmospheres while regulating fan speed for ventilation efficiency. The standard governs product design, manufacturing, and quality inspection for equipment used in hazardous mining locations.
