特点
Characteristics
本开关设备的结构用钢板弯制部件焊接经螺栓组装而成,整个柜体由固定的壳体和装有滚轮的可移开部件(手车)两部分组成。并用钢板和绝缘板分隔成手车室、母线室、电缆室和继电仪表室四个部分。外壳防护等级达到IP2X,其电气参数较高、系列性较强、结构合理。
本开关设备具有防止电气误操作功能的闭锁装置,以机械制止性的闭锁为主,设置接地开关辅以与模拟板核对的红、绿翻牌和高压带电显示装置的提示性防范措施,以达到如下“五防”闭锁的要求:a.防止带负荷推进或拉出一次隔离触头; b.防止误入带电间隔; c.防止接地开关处于闭合状态时(接地)关合断路器; d。防止误分误合断路器; e.防止带电合接地开关。
The structure of this switching equipment with curved steel-bolt assembly by welding parts from the entire fixed by the OEM shell and equipped with a wheel of the components can be removed(Handcart) made up of two parts. And steel and insulation board Handcart separated into rooms, bus room, cable meter relay rooms of four parts. Shell level of protection achieved IP2X, the higher its electrical parameters, the series of strong, well-structured.
With the switchgear misoperation to prevent electrical function of locking device to stop the machinery of the closed-based, set up by the earth switch and analog board to check the red, green and high-Flop live show device indicative of the preventivemeasures in order to achieve The following “five anti-” latch-up requirements:a. loading push forward to prevent or pulled out with a contact isolation;b.preventcharged into intervals;c. ground to prevent the switch in a closed state(ground) Thecombined circuit breaker; d.Prevent misuse of sub-co-breaker; e.charged together to prevent the grounding switch.
