電站測溫專用熱電偶

 隨著我國電力工業的不斷發展,急需各種適用于電站測溫專用熱電偶和熱電阻,以替代進口產品。本廠為了迎頭趕上國際先金水平,同時也為guojia節約外匯,先后從國外引進了專業制造技術和設備,并在原有產品基礎上,廣泛聽取設計院和電站用戶的意見,同時參考了美國的EBASCO規范,對產品進行重新設計,增加了新的品種,使整個配套系列的品種,規格完全符合國產或引進的30萬、60萬千瓦發電機組以及國內其它機組的配套需要,并以優異的質量來滿足市場。S7d壓力變(bian)送(song)(song)(song)器_差壓變(bian)送(song)(song)(song)器_液位(wei)變(bian)送(song)(song)(song)器_溫度(du)變(bian)送(song)(song)(song)器

注:“t”為感溫元件實測溫度,對于鉑電阻和銅電阻則為感溫元件實測溫度的覺對值。
 
公稱壓力:
一般是指在常溫下,保護管所能承受的靜態外壓而不破裂,試驗壓力一般采用公稱壓力的1.5倍。實際上,允許工作壓力不僅與保護管材料、直徑、壁厚有關,而且還與其結構形式、安裝方法、置入深度以及被測介質的流速、種類有關。
 
電站測溫專用熱電偶的絕緣電阻:
    常溫絕緣電阻的試驗電壓為直流500V。測量常溫絕緣電阻的大氣條件為:溫度15~35℃,相對濕度45%,大氣壓力86~106Kpa。
對于長度超過1米的熱電偶,它的常溫絕緣電阻值與其長度的乘積不小于100兆歐·米,
即:Rr·L≥100MΩm  L>1m
式中:Rr-熱電偶的常溫絕緣電阻值,MΩ;
L-熱電偶的長度,m。
對于長度等于或不足1米的熱電偶,它的常溫絕緣電阻值應不小于100 MΩ。
 
熱電阻絕緣電阻:
    常溫絕緣電阻的試驗電壓可取直流10~100V任意值,環境溫度應在15~35℃范圍內,相對濕度應不大于80%,常溫絕緣電阻值應不小于100 MΩ
