Low-voltage draw-out switchgear is suitable for power generation and power supply systems with three-phase AC frequency of 50Hz, rated working voltage of 400V(690V) and rated current of 4000A or less, and is used for power, power distribution, motor centralized control and capacitance compensation. Widely used in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other places, this product conforms to IEC60439-1, GB7251.1, JB/T 9661 and other standards. The cabinet adopts a new manufacturing process, and each functional unit adopts modular design, so that the unit combination is flexible and convenient, which can replace the GCS scheme and function on the market at present
? 結構說明 STRUCTURE DESCRIPTION
?新手搖式推進機構應用于單元抽屜，分手操和電操兩大類。為多圈省力推進方式，實現輕松、靈活、平穩推進與移出抽屜，三工位具有機械定位、顯示，并帶有“咔噠”的位置聲音提示功能，推進 630A 的三、四方案抽屜輕松靈活；合閘聯鎖具有再扣復位功能，推進機構原理與聯鎖機構技術優良。其中電操專用的聯鎖機構，能夠保障切斷開關才能移動抽屜，有效防止誤操作，實現搖手柄進入機構（可操作狀態）電操機構無法取電，只有拔出搖手柄，電操機構方可取電，使空開電動合閘，具有很高的操作安全性；
?新手拉式推進聯鎖機構應用于單元抽屜，具有三位置鎖定、顯示、合閘聯鎖位置輔助電源功能，開關再扣復位功能；
?新小型手拉式推進機構應用于 1/2、1/4 抽屜單元，具有三位置鎖定、顯示、合閘聯鎖位置輔助電源功能，開關再扣復位功能；
?抽屜新推進聯鎖機構具有分離、試驗、連接位置機械顯示，電氣接點與位置同步。
? The new hand-operated propulsion mechanism is applied to unit drawers, break-up operation and electric operation. It is a multi-circle laborsaving propulsion mode, which realizes easy, flexible and stable propulsion and removal of drawers. Three-station tool It has mechanical positioning and display, and has a "click" position sound prompt function, which makes it easy and flexible to promote the three-pole and four-pole drawers of 630A; Closing interlock has the function of re-locking and resetting, and the principle of propulsion mechanism and the technology of interlocking mechanism are advanced. Among them, the special interlocking mechanism for electric operation can ensure that the drawer can be moved only
by cutting off the switch, effectively preventing misoperation, and realizing that the electric operation mechanism can not take electricity when the rocking handle enters the mechanism (operational state), and only when the rocking handle is pulled out, the electric operation mechanism can take electricity, which makes the empty opening and electric closing have high operation safety;
? The new hand-pulled propulsion interlocking mechanism is applied to the unit drawer, which has the functions of three-position locking, display, closing interlocking position auxiliary power supply, and switch re-button reset function;
? The new small hand-pulled propulsion mechanism is applied to 1/2 and 1/4 drawer units, and has the functions of three-position locking, display, closing interlock position auxiliary power supply, and switch re-buckling reset function;
? The new push interlocking mechanism of drawer has mechanical display of separation, test and connection position, and the electrical contacts are synchronized with the position
