과제
광산 시스템에서 인버터는 “선택 장비”에서 “필수 장비”로 진화했습니다. 그 적용은 전통 상주파(전원 주파수 직결) 구동의 “고에너지 소비, 고마모, 저효율” 문제를 해결할 뿐 아니라 광산 지능화 전환의 핵심 기둥이 되고 있습니다. // 향후 방폭 기술, IoT 기술, 절전 알고리즘의 지속적 발전과 함께 인버터는 광산의 “무인화·지능 관제” 시스템에 깊이 통합되어 “안전·고효율·녹색” 생산 실현에 결정적인 기술 지원을 제공할 것입니다.
솔루션
The main underground ventilator in coal mines is a core auxiliary equipment for ensuring underground air quality and diluting gas concentration, which requires 24-hour continuous operation. Traditional power-frequency drives have pain points such as "high energy consumption for air volume adjustment (air door throttling loss reaches 30%-50%), large starting impact (inrush current is 5-7 times the rated value), and slow gas linkage response". For this scenario, inverter application solution takes "safety and explosion prevention as the premise, on-demand air supply for energy conservation as the core, and intelligent linkage to ensure safety" as its goals, so as to achieve efficient and safe operation of the ventilator. The basic plan is as follows:
inverter selection: Focus on explosion prevention and stability, and select flameproof vector control inverters.
Control logic: Dynamic speed regulation with gas linkage, which is deeply linked with the underground gas monitoring system and PLC control cabinet to build a "gas concentration - air volume" closed-loop control.
Installation and protection: Adapt to the harsh underground environment to avoid causing safety risks.
