                產品簡介

                Brief introduction to the products

                KYN28-24鎧裝移開式交流金屬封閉開關設備(以下簡稱開關設備),適用于戶內三相50/60Hz,額定電壓24KV的單母線及單母線分段電力系統的成套配電裝置。


                主要應用于電廠、中小型發電機發電、工礦企業配電以及電業系統的二次變電所,作為接受和分配電能并對電路實行控制、保護和監測。


                本開關設備具有防止帶負荷推拉斷路器手車、防止誤分合斷路器、防止接地開關處在閉合位置時關合斷路器、防止誤入帶電間隔、防止在帶電時誤合接地開關的“五防”聯鎖功能。KYN28-24開關設備配置性能優良的VS1系列中置式高壓交流真空斷路器或固封式真空斷路器。開關設備二次回路配置先進可靠的控制保護元件,母線采用熱縮絕緣材料或環氧涂覆手段,優化電極形狀,柜體結構緊湊,方案組合靈活方便。


                KYN28-24KV Armored Moving AC Metal-Enclosed Switchgear (hereinafter referred to as switchgear) is a complete set of power distribution device, suitable for single bus and single bus segment power system with indoor three-phase 50/60Hz and rated voltage 24KV.


                It is mainly used for the power plants, small and medium-sized generators for power generation, power distribution of the industrial and mining enterprises and the secondary substation of electric system to receive and distribute electric energy and control, protect and monitor the electric circuits.


                The switchgear has the "Five prevention” interlock functions, namely, preventing from pushing and pulling the handcart of circuit breaker on load, preventing error switching on / off of the circuit breaker, preventing from switching off the circuit breaker when the grounding switch is in the switching-off position, preventing from entering into the live interval by mistake and preventing from switching off the grounding switch by mistake when it is charged. KYN28-24KV switchgear is equipped with VS1 series infix high-voltage AC vacuum circuit breaker or seal type vacuum circuit breaker with excellent performance. The secondary circuit of the switchgear is equipped with the advanced and reliable control and protection components. The bus adopts the method of heat-shrinkable insulating material or epoxy for coating. The electrode shape is optimized, and the cabinet structure is compact. The combination of the programs is flexible and convenient.
