Characteristic
Metal-cald and partition completely, efectively pre-
vent faults spreading.
IP4X The low voltage section is completely separated
from the high voltage sections.
Enclosure protection degree is IP4X, protect against
electric shock and ingress of solid foreign bodies.
Simple but effective interlocking prevents
maloperation.
Space is provided for multiple cable connections.
Installation and maintenance is convenient.
Withdrawble part of the same design are mutually
interchangeable, an exchange of VCB is very
simple.

Construction
The basic structure of the switchgear panel comprises
the panle itself and withdrawable part.
The panel is constructed by bolting together.Enclosure
and internal partition are of anticorrosive steel sheets.
The panel consists of four separate compartments, that is
truck compartment, busbar compartment, cable
compartment, low-voltage maintenance type, double-face
maintenance type. Withdrawable part can be classified

KYN28-12系列金屬鎧裝移開式開關(guān)設(shè)備是一種常見的高壓開關(guān)柜產(chǎn)品，由瑞士施耐德（Schneider）公司推出并被廣泛應(yīng)用于35kV及以下電力系統(tǒng)中。它采用高質(zhì)量的金屬鎧裝結(jié)構(gòu)設(shè)計(jì)，具有良好的防護(hù)性能和抗電磁干擾能力，確保操作人員的人身安全以及電網(wǎng)設(shè)備的正常運(yùn)行。 該系列產(chǎn)品的主要特點(diǎn)包括： 1. **金屬鎧裝外殼**：全封閉、金屬屏蔽，具備優(yōu)良的防塵、防潮、防腐蝕性能，提高了開關(guān)柜在惡劣環(huán)境下的使用穩(wěn)定性。 2. **移開式設(shè)計(jì)**：開關(guān)柜可通過將母線室與斷路器室分離開來實(shí)現(xiàn)獨(dú)立的操作，便于檢修維護(hù)和擴(kuò)建工作，同時也方便了設(shè)備的運(yùn)輸和安裝。 3. **集成化功能**：配置有高壓斷路器、負(fù)荷開關(guān)、隔離開關(guān)、接地開關(guān)等核心元件，以及相關(guān)的保護(hù)裝置如過電流保護(hù)、零序保護(hù)、短路速斷保護(hù)等，滿足多種電力系統(tǒng)需求。 4. **安全性高**：采用了五防聯(lián)鎖機(jī)制，有效防止誤操作帶來的安全隱患，保證了人身安全和電網(wǎng)設(shè)備的安全運(yùn)行。 總之，KYN28-12系列金屬鎧裝移開式開關(guān)設(shè)備憑借其技術(shù)先進(jìn)、可靠性高、操作簡便等特點(diǎn)，在高壓電力系統(tǒng)中得到了廣泛應(yīng)用，并成為國內(nèi)外主流高壓開關(guān)柜產(chǎn)品之一。
