Tantangan
Pada sistem tambang, inverter telah berevolusi dari “peralatan opsional” menjadi “peralatan wajib”. Penerapannya tidak hanya menjawab masalah “konsumsi tinggi, keausan tinggi, efisiensi rendah” penggerak frekuensi-jaringan tradisional, tetapi juga menjadi pilar inti transformasi cerdas tambang. // Ke depan, seiring kemajuan teknologi antiledak, IoT, dan algoritme hemat energi, inverter akan terintegrasi mendalam ke sistem “tambangan tanpa awak dan kendali cerdas”, memberikan dukungan teknis krusial bagi produksi tambang yang “aman, efisien, dan hijau”.
Solusi
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.
