電蒸汽鍋爐通過接地線把漏電流導入大地

電蒸汽鍋爐通過接地線把漏電流導入大地

1、安全性:①漏電保護:當鍋爐發生漏電時,通過漏電斷路器及時切斷電源,確保人身安全。

②缺水保護:當鍋爐缺水時及時切斷加熱管控制電路,防止加熱管發生干燒損壞,同時控制器發出缺水#指示。

從如果出現樢??場認可。通過接地線把漏電流導展制約等③接地保護:當鍋爐外殼帶電時,通過接地線把漏電流導入大地,從而確保人身安全。

通常保護接地線應與大地之間作良好的金屬聯接,常用深埋在地下的角鐵、接地電阻不得大于4Ω。能增強活性。

2、方便性:①電源引入電控箱后,一鍵操作,鍋爐便進入(或脫離)全自動運行狀態。

②鍋爐內水量減少,控制系統自動通過補水泵把水從水箱補充到鍋爐內。電加熱蒸汽鍋爐ISA等具有更多的特點。

3、合理性:為合理有效的使用電能,特別將加熱功率分為數段,并由控制器自動循環投入(切斷)用戶根據實際需要確定好加熱功率后,只需合上相應漏電斷路器(或按下相應的投切開關)即可。通過

后臺加熱管的分段循環投切,降低了鍋爐在運行中對電網的沖擊。

4、電加熱蒸汽鍋爐入大地可靠性:鍋爐本體使用氬弧焊打底,手工焊蓋。
