MNS低压抽屉柜是一个集成式的结合体，其保护功能要从不同的部件上去分析。那么MNS低压抽屉柜外壳的保护功能如何？今天就从外壳方面分析起来。
MNS low-pressure cabinet of drawers is an integrated combination, its safety protection function should be analyzed from different parts. So how about the protection function of the MNS low pressure chest of drawers shell? Today from the shell analysis.
配电柜系统内部：柜体上部为母线室、前部为电器室、后部为电缆进出线室，各室间有钢板或绝缘板作隔离，以保证。
Internal safety of power distribution cabinet system: the upper part of the cabinet is the bus room, the front part is the electrical room, and the back part is the cable inlet and outlet room. There are steel plates or insulation plates between the rooms to ensure safety.
保护人身：MNS低压抽屉柜小室的门与断路器或隔离开关的操作手柄设有机械联锁，只有手柄在分断位置时门才能开启。
Personal safety: The door of the MNS low-voltage cabinet compartment is mechanically interlocked with the operating handle of the circuit breaker or disconnector. The door can only be opened when the handle is in the disconnecting position.
高短路自我保护：水平母线采用柜后平置式排列方式，以增强母线抗电动力的能力，是使主电路具备高短路强度能力的基本措施。
High short circuit self-protection: the horizontal bus adopts the horizontal arrangement after the cabinet, in order to enhance the anti-electric power ability of the bus, which is the basic measure to make the main circuit have the ability of high short circuit strength.
母线自我保护：母线用高强度阻燃型、高绝缘强度的塑料功能板保护，具有抗故障电弧性能，使运行维修可靠。
Busbar self-protection: busbar is protected by high-strength flame-retardant plastic functional board with high insulation strength, which has anti-fault arc performance and makes operation and maintenance safe and reliable
模块的设计保护：采用标准模块设计，分别可组成保护、操作、转换、控制、调节、测定、指示等标准单元，可以根据要求任意组装。
Module design protection: using standard module design, respectively can be composed of protection, operation, conversion, control, adjustment, measurement, indicating and other standard units, can be arbitrarily assembled according to requirements.
柜体内外隔离保护：
MNS低压抽屉柜采用高强度阻燃型工程塑料，有效加强了防护性能；且柜体可按工作环境的不同要求选用相匹配的防护等级。
Cabinet inside and outside isolation protection: MNS low-pressure drawer cabinet adopts high-strength flame-retardant engineering plastic, which effectively strengthens the protection and safety performance; And the cabinet can be selected according to the different requirements of the working environment to match the level of protection.
How does the MNS low pressure chest of drawers protect the casing? The safety protection function is very powerful, of course, we also need to know more about the safety protection function of other components of the cabinet. To learn more, visit www.tongyuhengcheng.com.
