style="text-indent:25px">【浩蘊自動化】什么是電氣隔離開關？隔離開關是沒有滅弧裝置的開關，不能有效的斷開短路電流，只能手動斷開，一般應用于配電柜總開關。隔離開關不能在有負荷的情況下操作，要在斷路器斷開之后，才能斷開隔離開關，隔離開關有明顯的斷開點，以便于電氣設備的維修和檢測，樣式就跟家里**老式的刀閘差不多，老式的刀閘有保險絲，但是隔離開關沒有，只能通過手動通斷，在配電柜上有個上下?lián)u把可以斷開和恢復隔離開關。隔離開關常用于高電壓電氣的開關，是高壓電氣中使用**多的一種開關，比如變電站，電廠等高壓電氣中。杭州32A

(2)在元雷電活動時拉合避雷器。 (3)拉合220KV及以下母線和直接連接在母線上的設備的電容電流，經(jīng)試驗允許的500KV空載母線和拉合3/2接線母線環(huán)流。 (4)在電網(wǎng)元接地故障時，拉合變壓器中性點接地開關。 (5)與斷路器并聯(lián)的旁路隔離開關，當斷路器合好時，可以拉合斷路器的旁路電流。 (6)拉合勵磁電流不超過2A的空載變壓器、電抗器和電容器電流不超過5A 的空載結(jié)路。 (7)對于3/2斷路器接線，某一串斷路器出現(xiàn)分、合閘閉鎖時，可用隔離開關來解環(huán),但要注意其他串著的所有斷路器必須在合閘位置。 (8)雙母線單分段接線方式，當兩個母聯(lián)斷路器和分段斷路器中某斷路器出現(xiàn)分、合閘閉鎖時, 可用隔離開關斷開回路。操作前必須確認三個斷路器在合位，并取下其操作制熔斷器。</p><p style="text-indent:25px">【浩蘊自動化】負荷開關與隔離開關的區(qū)別什么是負荷開關？是具有簡單的滅弧裝置，可以帶負荷分、合電路的控制電器。能通斷一定的負荷電流和過負荷電流，但不能斷開短路電流，必須與高壓熔斷器串聯(lián)使用，借助熔斷器來切除短路電流。負荷開關的作用： 1. 開斷和關合作用。由于它有一定的滅弧能力，因此可用來開斷和關合負荷電流和小干一定倍數(shù)(通常為3-4倍)的過載電流;也可以用來開斷和關合比隔離開關允許容量更大的空載變壓器，更長的空載線路，有時也用來開斷和關合大容量的電容器組。 2. 替代作用。負荷開關與限流熔斷器串聯(lián)組合可以代替斷路器使用。即由負荷開關承擔開斷和關合小于一定倍數(shù)的過載電流，而由限流熔斷器承擔開斷較大的過載電流和短路電流。 3. 負荷開關與限流熔斷器串聯(lián)組合成一體的負荷開關，在國家標準中規(guī)定稱為“負荷開關-熔斷器組合電器”。熔斷器可以裝在負荷開關的電源側(cè)，也可以裝在負荷開關的受電側(cè)。當不需要經(jīng)常掉換熔斷器時，宜采用前一種布置，以便利用負荷開關兼作隔離開關的功能，用它來隔離加在限流熔斷器上的電壓。隔離開關的的圖形和文字符號怎么看?</p><div
