style="text-indent:25px">電流互感器的主要所用是用來將電路中的大的電流轉(zhuǎn)換為小電流，以供測量和繼電保護只之用。大家應(yīng)該知道在發(fā)電、變電、輸電、配電過程中由于用電設(shè)備的不同，電流往往從幾十安到幾萬安都有，而且這些電路還可能伴隨高壓。那么為了能夠?qū)@些線路的電路進行監(jiān)控、測量，上海電流互感器售價多少錢，上海電流互感器售價多少錢，上海電流互感器售價多少錢，同時又要解決高壓、高電流帶來的危險，這時就需要用到電流互感器了。有些人可能見過電工用的鉗形表，這是一種用來測量交流電流的設(shè)備，它那個“鉗”便是穿心式電流互感器。電流互感器只有一個電流比。上海電流互感器售價多少錢</p><div

style="text-indent:25px">電流互感器可用來擴大交流電流表的量程。在使用時，它的原線圈應(yīng)與待測電流的負載線路相串聯(lián)，副邊線圈則與電流表串接成閉合回路。電流互感器的原線圈是用粗導線繞成，其匝數(shù)只有一匝或幾匝，因而它的阻抗極小。原線圈串接在待測電路中時，它兩端的電壓降極小。副線圈的匝數(shù)雖多，但在正常情況下，它的電動勢E2并不高，大約只有幾伏。電流互感器通過負載的電流就等于副邊線圈所測得的電流與變流比Ki之乘積。如果電流表同一只**的電流互感器配套使用，則這安培表的刻度就可按大電流電路中的電流值標出。電流互感器次級電流比較大值，通常設(shè)計為標準值5A。不同的電流的電路所配用的電流互感器是不同的。為了安全起見，電流互感器副線圈的一端和鐵殼必須接地。北京磁通門電流互感器兩相電流差接線方式由兩臺電流互感器和一只電流繼電器組成。</p><div

style="text-indent:25px">電流互感器只能一點接地。對于電流互感器的二次回路來說是保護接地。接地的意義在于避免在多個接地點之間產(chǎn)生地電流，對互感器采集的信息進行干擾。兩點接地會導致二次電流回路被分流，即部分電流會通過其中一點流入大地再通過另一點流回，進而導致所接保護/測量/計量裝置電流采樣不準，極易造成保護不正確動作。這一點不論是在電流互感器的安裝還是運用方面都是需要注意的，工作保證效率的同時也要注意機器和人身的安全。這樣才能使電流互感器工作起來更加快捷穩(wěn)定。</p><p style="text-indent:25px">電流互感器的基本結(jié)構(gòu)主要由一次繞組，二次繞組和鐵芯構(gòu)成，一次，二次和鐵芯之間都有絕緣。簡單的電流互感器，有一個一次繞組一個二次繞組和一個鐵芯。這樣的電流互感器也只有一個電流比。為了提高電流互感器的準確度，一般都對電流互感器的誤差進行補償，這樣除了上述一次，二次繞組和鐵芯之外，有的還另外繞制輔助線圈或者加入輔助鐵芯。10千瓦以上高壓電流互感器，為了使用方便，經(jīng)常把幾個**的互感器鐵芯繞組。這就是電流互感器的基本結(jié)構(gòu)。電流互感器接入式測量：采用二臺電流互感器，接成不完全星形。</p><div
