      防爆空調廠家淺談防爆電器

      2016-10-18 10:22:13
      我國現使用的隔爆型防爆電器,隔爆腔有機械閉鎖裝置,不切斷電源,就不能打開。但在接線腔內就沒有機械閉鎖裝置,只有一個提示牌,在帶電條件下也能夠開啟接線腔。正因為隔爆型防爆電器存在著這一缺陷,才使得個別作業人員有違章或誤操作帶電開啟接線腔的可能。對此國家煤礦安全監察局領導非常重視,多次提及此問題,能否采取一定技術措施,保證工作人員無法帶電作業。大力推廣隔爆型分級閉鎖專利技術提高我國整體防爆安全水平。 
        我國防爆電器行業前幾年總體經濟增速雖比年有所放緩,但各項經濟指標仍保持較快增長,經濟發展和取得的經濟效益也是近幾年中較好的。其中,礦用防爆電器伴隨煤炭工業的發展進入了平穩、快速的發展時期。在行業快速發展的同時,主要存在幾個方面的問題:產品銷售流通領域較為混亂,部分小型企業產品質量問題突出,低價傾銷現象普遍,擾亂了正常的市場秩序,同時給用戶的安全生產埋下了隱患,不利于企業發展和行業的技術進步防爆電器行業集中度過低,生產企業過多,而且大多數生產企業規模過小,企業管理水平低產品技術含量不高,技術水平偏低,產品更新速度慢。
           電氣安全產品的不完善性和局限性:防爆電器傳統的安全措施是采用防爆外殼、本質安全電路及各種保護裝置。多年來的運行實踐表明,這些安全措施對防止電火引燃,引爆、保障人身女安全起到了重要作用。在對我國隔爆型真空電磁起動器進行調研分析的基礎上,針對現有隔爆開關接線腔本身存在的未實現電氣機械閉鎖問題和我國管理使用水平,研制成功了新型隔爆型分級閉鎖真空磁力起動器,并取得了國家專利該系列隔爆型分級閉鎖真空磁力起動器,實現了開啟接線腔蓋斷電,分級閉鎖,從技術上防止了由于違章及誤操作打開真空電磁起動器接線腔蓋后的帶電作業和上一級的誤送電;該系列隔爆型分級閉鎖真空磁力起動器具有結構簡單的特點。
