1、產(chǎn)品概述
ZW32-24型自動(dòng)重合器其額定zui大連續(xù)電流為630A，對(duì)稱開斷額定值為16KA。是電站或柱上安裝的戶外開關(guān)設(shè)備。主要用于額定電壓12KV、24KV和40.5KV,三相交流50HZ輸配電系統(tǒng)中額定電流的開合以及三相三次重合閘，過負(fù)荷保護(hù)，三段式過流保護(hù)，三段式零序電流保護(hù)，失壓保護(hù)，同時(shí)具有故障錄波，小電流接地選線功能。其中三段式過流保護(hù)通過方式字可選擇經(jīng)低壓閉鎖或經(jīng)方向閉鎖。重合閘有檢無(wú)壓和檢同期功能。產(chǎn)品設(shè)有RS232及LONWORKS通訊接口可與監(jiān)控系統(tǒng)連接，便于實(shí)現(xiàn)四遙及遠(yuǎn)方通訊，定時(shí)全面的自檢系統(tǒng)大大提高了配電系統(tǒng)的可靠性。
The rated Max. continuous current of ZW32-□Z type automatic re-closer is 630A,symmetrical breaking rated value is 16KA.It’s a kind of power station or pillar install outdoor switchgear. It is main used for makingbreaking rated current in transmissiondistribution power system of three-phase A.C,50HZ,rated voltage 12KV,24kv40.5kv,and three phase thrice re-closing, over load protection, three
Phase zero sequence current protection ,lose voltage protection. At the same time,
It has function of record fault wave, little current earthing optional line. Its
three phase over current protection pass mode can chose through low voltage lock or through direction. Re-closing can check no voltagecheck the corresponding period. The product has RS232LONWORKS communication adapter, can connect with inspection system, so to realize distant communication, the timing self check system greatly increase reliability of power distribution system.
