500-5030

500-5030引風(fēng)機功率大，在工頻供電的情況下，需要龐大的降壓啟動裝置。為此主回路需要配備大功率接觸器、電抗器等降壓啟動裝置，這樣會增加主回路中的電氣設(shè)備數(shù)量。在頻繁啟動和制動的情況下，設(shè)備故障率會增加，維修量會增加，甚至?xí)仁瑰仩t停機處理故障，無法正常供汽，影響用戶的正常生產(chǎn)，不僅造成巨大的經(jīng)濟損失，還會影響供熱單位的聲譽。

在頻繁啟動和制動的情況下，產(chǎn)生的啟動浪涌電流會對電網(wǎng)和風(fēng)機系統(tǒng)產(chǎn)生的影響，直接影響電網(wǎng)的供電質(zhì)量和風(fēng)機系統(tǒng)的運行。
