產(chǎn)品概述：

Product Overview：

KYN28-12內(nèi)金屬鎧裝移開(kāi)式開(kāi)關(guān)設(shè)備是三相交流50(60)Hz額定工作電壓12千伏、額定工作電流1250A的戶(hù)內(nèi)成套配電裝置。其母線(xiàn)系統(tǒng)為單母線(xiàn)宜可派生出單母線(xiàn)帶旁路和雙母線(xiàn)結(jié)構(gòu)。具有實(shí)現(xiàn)"五防"閉鎖功能。該柜體既能配用ZN63 (VSI)真空斷路器，也可配用ABB公司的VD4真空斷路器，實(shí)為一種性能優(yōu)良的配電裝置。

KYN28-12 indoor metal armored withdrawable switchgear is the indoor distribution equipment assembly, of which the three-phase AC 50(60) Hz rated working voltage is 12kV and the rated working current is 1250A. Its busbar system adopts single busbar; however, the structure of single busbar with bypass and the structure of dual busbar can also be derived. The switchgear has the "five protection" interlocking function. Since it can be used in combination with ZN63 (VSI) vacuum circuit breaker or VD4 vacuum circuit breaker from ABB Group, it is the power distribution equipment with excellent performance. 

適用范圍：

Scope of Application

主要適用于發(fā)電廠(chǎng)、中小型發(fā)電機(jī)送電、工礦企事業(yè)配電及電力系統(tǒng)的二次變電所受電、饋電及大型高壓電動(dòng)機(jī)啟動(dòng)等，實(shí)行控制保護(hù)、監(jiān)測(cè)之用。

It is mainly used for the power transmission of power plants and medium- and small-sized generators, power distribution of industrial and mining enterprises and institutions, power receiving and feed of secondary substation of power system and start-up of large-sized HV motors, realizing the protection and monitoring functions.
