景泰(tai)電(dian)氣在高低(di)壓成套配(pei)電(dian)中，各種機柜各有利弊。比如(ru)珠峰電(dian)氣的(de)(de)ZFRM6-12全封(feng)閉全絕緣充氣柜，憑借其高性價比的(de)(de)市場(chang)定(ding)(ding)位，迅速成為充氣柜中的(de)(de)一匹黑馬，并在相對較短的(de)(de)時間內(nei)贏得了眾多客戶的(de)(de)認(ren)可。所(suo)以今天，我們主(zhu)要(yao)談談低(di)壓開關柜中常見的(de)(de)柜型GGD、GCK、GCS和MNS開關柜的(de)(de)區別： 外觀上，GGD是固(gu)定(ding)(ding)柜，而GCK、GCS、MNS是抽(chou)屜(ti)，后三者的(de)(de)推進機構不同。

尤其是(shi)從(cong)ABB公(gong)司進口的(de)MNS。GCS通過模(mo)仿MNS的(de)水(shui)平總(zong)線和(he)進出線進行優化。 2.從(cong)實(shi)(shi)際(ji)使(shi)用(yong)(yong)來看，箱式變壓器普遍采用(yong)(yong)GGD，而(er)在(zai)配電(dian)室，大(da)多以GCK、GCS、MNS的(de)抽(chou)(chou)屜柜為主(zhu)，主(zhu)要(yao)是(shi)因為抽(chou)(chou)屜柜占(zhan)用(yong)(yong)空間較小，后期維護使(shi)用(yong)(yong)時操作(zuo)更安全(quan)(quan)、簡(jian)單； 3.在(zai)使(shi)用(yong)(yong)成本方(fang)面(mian)，GGD的(de)成本總(zong)體(ti)上要(yao)比同規格的(de)抽(chou)(chou)屜柜低很多。 在(zai)實(shi)(shi)際(ji)生產過程中，三種抽(chou)(chou)屜的(de)區別不(bu)大(da)，主(zhu)要(yao)是(shi)GGD和(he)GGD的(de)區別。簡(jian)單來說，GGD更實(shi)(shi)惠，抽(chou)(chou)屜更安全(quan)(quan)。選擇哪種機(ji)柜類型，這個要(yao)根據實(shi)(shi)際(ji)情況來選擇。
