低壓狀態下的抽屜柜擁有更方便合適的總體架設構造，配合美觀的布局方式，使安裝過程更加簡單便利。在市場上，抽屜式低壓開關柜受熱捧。低壓抽出式開關柜沒有刀開關，縮小了元件安裝的空間，柜內增加了回路數，相同規格的抽屜可以互換使用，減少了停電時間，在低壓成套設備中應用廣泛。各種性能都超過了固定柜。

The drawer cabinet under low voltage condition has a more convenient and suitable overall erection structure, and the beautiful layout makes the installation process more simple and convenient. Drawer-type low-voltage switchgear is popular in the market. The low-voltage draw-out switch cabinet has no knife switch, which reduces the space for component installation, increases the number of loops in the cabinet, and the drawers of the same specification can be interchanged, reducing the power outage time, and is widely used in low-voltage complete equipment. All kinds of performance have exceeded the fixed cabinet.

MNS低壓抽屜柜內部功能和單元結構都存在差異。熱能對于其發揮的配電性能會造成很大影響，MNS低壓抽屜柜表現出的優良抗熱性能展現了其優良的穩定屬性，在特殊情況下，電弧出現意外故障此時便彰顯了預設硬件對于該情況的防護能力，所以，在設計時，預設機構對于性能有著這些影響。

There are differences in internal functions and unit structures of MNS low-voltage drawer cabinets. Thermal energy will have a great impact on its power distribution performance. The excellent heat resistance performance of MNS low-voltage drawer cabinet shows its excellent stability properties. Under special circumstances, the unexpected failure of the arc will show the protection ability of the preset hardware for this situation. Therefore, the preset mechanism has these effects on the performance during design.

開關柜本體需要滿足兩重穩定性，熱穩定性和動穩定性。柜體動熱穩定性能是生產商考慮的問題。在大電流的情況下，一且出現短路，柜體應具備承受短路電流的能力，對柜體的結構強度要求很高，作為低壓柜的設計人員，先應考慮水平主母排的固定方式及位置放置。

The switch cabinet body needs to meet the dual stability, thermal stability and dynamic stability. The dynamic and thermal stability of the cabinet is a problem considered by the manufacturer. In the case of large current, once there is a short circuit, the cabinet body should have the ability to withstand the short circuit current, and the structural strength of the cabinet body is very high. As the designer of the low-voltage cabinet, the fixed mode and position of the horizontal main busbar should be considered first.

如斷路器樁頭與銅母排搭接處(母排采用鍍銀處理)、注意連接部位緊固螺栓的壓力、測導體材料電導率是否滿足要求等等，但其接觸面積由于太小，使得接觸電阻太大發熱而使溫度過高。電弧是一種氣體游離放電現象，也是一種等離子體。

For example, the overlap between the circuit breaker pile head and the copper busbar (the busbar is treated with silver plating), pay attention to the pressure of the fastening bolts at the connection part, and measure whether the conductivity of the conductor material meets the requirements, but the contact area is too small, which makes the contact resistance too large and the temperature too high. Arc is a kind of gas free discharge phenomenon, and also a kind of plasma.

此外抽屜開關設備的溫升，也是考查柜體結構設計的一一個重要指標。柜內的溫升與外殼的安裝形式、外殼的尺寸、是否帶通風槽以及通風槽的大小，內部水平隔板數，元器件的有效損耗及抽屜單元個數等參數有關。抽出式柜的通風設計中功能單元部分的通風很重要。

In addition, the temperature rise of the drawer switchgear is also an important index for examining the structural design of the cabinet. The temperature rise in the cabinet is related to the installation form of the shell, the size of the shell, whether there is a ventilation slot and the size of the ventilation slot, the number of internal horizontal partitions, the effective loss of components and the number of drawer units and other parameters. The ventilation of the functional unit is very important in the ventilation design of the draw-out cabinet.
