GCK低壓開關柜

發布單位:四川電器    發布日期: 2017-06-03


產品概述


GCK低壓抽出式開關柜廣泛應用于發電廠,變電所,廠礦企業和高層建筑的動力配電中心PC和電動機控制中心MCC,作為交流50-60Hz,額定工作電壓為660V及以下,額定電流為4000A及以下的發、供電系統中配電、電動機集中控制,無功補償使用的低壓成套配電裝置。


產品特點


■ GCK型低壓抽屜式開關柜的柜架主材采用展型鋼材,利用角板定位,螺栓連接的無焊接結構,零部件的成型尺寸、開孔尺寸及設備間隔實行模數化。柜體分成母線室、功能單元室、電纜室三個相互隔離的區間,能有效防止事故擴散和便于帶電維修。
■ GCK型低壓抽屜式開關柜的功能單元,隨著抽屜的移出,使單元器件完全與導電的垂直母線脫離,可安全地進行電器設備的更換和維修。功能單元的主電路插頭、輔助電路插頭具有插接牢靠、受力均勻、插拔平衡的特點,保證可靠連接。單元隔室采用金屬板隔開,隔室中的活門,隨著抽屜的拉出能自動封閉,保證了人體不能觸及帶電的垂直母線,確保了安全。
■ GCK型低壓抽屜式開關柜的水平母線安裝在柜體頂部,為三相五線制或三相四線制,規格按計算負荷選擇或由用戶指定,垂直母線采用無鹵無毒、阻燃的工程塑料外殼封閉。


使用環境要求


1、周圍空氣溫度不高于+40℃,不低于-5℃,24h內的平均溫度不得高于+35℃,超過時,需根據實際情況降容運行;
2、戶內使用:使用地點的海拔不得超過2000m
3、周圍空氣相對溫度為+40℃時不超過50%,在較低溫度時允許有較大的相對溫度,如+20℃時為90%,應考慮到由于溫度的變化可能會偶然產生凝露的影響;
4、裝置安裝時與垂直面的斜度不超過5℃,且整組柜列相對平整(符合GBJ232-82標準);
5、裝置應安裝在無劇烈震動和沖擊以及不足以使電器元件受到不應有腐蝕的場所;
6、用戶有特殊要求可以與制造廠:四川電器集團股份有限公司協商解決
