高壓(ya)開(kai)關(guan)(guan)柜是指用(yong)于電(dian)(dian)(dian)力系統(tong)發電(dian)(dian)(dian)、輸電(dian)(dian)(dian)、配電(dian)(dian)(dian)、電(dian)(dian)(dian)能(neng)轉換(huan)和(he)消耗(hao)中(zhong)起通斷、控制或保護等作用(yong)。高壓(ya)開(kai)關(guan)(guan)柜按作電(dian)(dian)(dian)壓(ya)等級(ji)在3.6kV~550kV的電(dian)(dian)(dian)器產品，高壓(ya)隔離開(kai)關(guan)(guan)與接(jie)地開(kai)關(guan)(guan)、高壓(ya)負荷開(kai)關(guan)(guan)、高壓(ya)自動(dong)重合與分段(duan)器，高壓(ya)操作機構(gou)、高壓(ya)防爆(bao)配電(dian)(dian)(dian)裝(zhuang)置和(he)高壓(ya)開(kai)關(guan)(guan)柜等幾大類。

開關柜(ju)具有(you)架(jia)空進(jin)出線(xian)(xian)、電(dian)纜進(jin)出線(xian)(xian)、母線(xian)(xian)聯(lian)絡等(deng)功能(neng)。主(zhu)要適用于發電(dian)廠、變電(dian)站(zhan)、石油(you)化工(gong)(gong)、冶金軋(ya)鋼、輕工(gong)(gong)紡織、廠礦企業和(he)住宅小區、高(gao)層建(jian)筑(zhu)等(deng)各(ge)種不同場所(suo)。

開關(guan)柜應(ying)滿足“交(jiao)流(liu)金屬封(feng)閉開關(guan)設備標準(zhun)”的有關(guan)要求，由(you)柜體和斷(duan)路(lu)器二大部分組成，柜體由(you)殼體、電器元件(包括絕(jue)緣件)、各(ge)種(zhong)機(ji)構、二次端子及連線等組成。

1、冷軋(ya)鋼板或(huo)角鋼(用于焊接(jie)柜);

2、敷(fu)鋁鋅(xin)鋼(gang)板(ban)或鍍鋅(xin)鋼(gang)板(ban)(用于組(zu)裝柜).

3、不銹鋼板(不導磁(ci)性(xing)).

4、鋁板((不導磁性).

5、柜體的功能單元：

6、主(zhu)母(mu)線(xian)室(shi)(一(yi)般主(zhu)母(mu)線(xian)布置按“品(pin)”字(zi)形或(huo)“1”字(zi)形兩種結構

7、斷路(lu)器室(shi)

8、電纜室
