　　6. High quality surface protection cabinets undergo strict degreasing, rust removal, and phosphating treatment on their surfaces, followed by two layers of primer spraying and surface coating using electrostatic powder coating technology. The anti-corrosion level of the cabinet is indoor medium anti-corrosion type: F1. The cabinet surface is sprayed with small wrinkle plastic powder to meet the visual requirements of the power industry for non reflective and non dazzling screen cabinet surfaces. Its plastic powder does not contain hazardous chemicals, lead, or other heavy metals, and has the advantages of being non-toxic, odorless, pollution-free, and having strong adhesion. The coating has a soft and harmonious appearance, with excellent quality.

　　7、机柜的标准化、模块化设计

　　7. Standardization and modular design of cabinets

　　目前公司对标准化、模块化系数的初步要求是不小于70%，不过还应该根据产品客户化要求的不同而有所区别。为达到较高的标准化、模块化系数，应遵循以下一些通用准则：柜体外观标准化，公司维谛EG110色（小皱纹灰白色）；柜体尺寸标准化，有800宽X600深X2260高（mm），600宽X600深X2260高（mm）两种标准；机柜各单元模块化,可将柜体分解成平行小装配单元，尽量采用积木式结构，以利于提高生产率、降低工艺复杂程度。(一般可分解为交流单元、监控单元、模块单元、直流馈出单元、维护单元、防护单元等)。

　　At present, the company's preliminary requirement for standardization and modularization coefficient is not less than 70%, but it should also be differentiated according to the different customer requirements of the product. To achieve a high degree of standardization and modularity, the following general principles should be followed: standardization of cabinet appearance, the company recommends Weidi EG110 color (small wrinkles gray white); The cabinet size is standardized, with two standards: 800 wide X600 deep X2260 high (mm) and 600 wide X600 deep X2260 high (mm); Each unit of the cabinet is modularized, and the cabinet can be decomposed into parallel small assembly units, using a modular structure as much as possible to improve productivity and reduce process complexity. (Generally can be decomposed into AC unit, monitoring unit, module unit, DC feed out unit, maintenance unit, protection unit, etc.).

　　为方便设备运行过程的维护和检修，对装有器件的机柜面板采用开启灵活的内门形式，柜体内配有照明和单相交流220V电源插座。

　　For the convenience of maintenance and repair during the operation of the equipment, the cabinet panel equipped with components adopts a flexible inner door form, and the cabinet is equipped with lighting and single-phase AC 220V power sockets.

　　许多零部件的寿命较短，有的容易发生故障，在整个产品的寿命周期内需要多次更换，如保险装置，防雷装置、风扇、电源、光器件等，为更换损坏零部件而拆卸的零部件数量不超过2个（其中一个可能是盖板、门等，另外一个可能是紧固件）;另一方面，有许多零部件在使用过程中需要清洗、检查等例行的维护，如防尘网等。这些零部件的可拆卸性和可维护性符合以下规则：易损、易坏零部件、器件安排在比较明显、容易更换的位置且用户进行维护的零部件要采用易拆卸的装联方式，如卡接、插接(如接插件连接)、螺纹连接等，而避免采用半性连接或性连接方式。

　　Many components have a short lifespan and are prone to failure, requiring multiple replacements throughout the entire product lifecycle, such as safety devices, lightning protection devices, fans, power supplies, optical components, etc. The number of components disassembled to replace damaged parts should not exceed 2 (one of which may be a cover plate, door, etc., and the other may be a fastener); On the other hand, there are many components that require routine maintenance such as cleaning and inspection during use, such as dust nets. The disassembly and maintainability of these components comply with the following rules: vulnerable and easily damaged components, devices arranged in prominent and easily replaceable positions, and components maintained by users should use easily detachable assembly methods, such as card connections, plug connections (such as connector connections), threaded connections, etc., while avoiding semi permanent or permanent connections.

　　9、机柜边框、棱角做光滑处理

　　9. Smooth the cabinet frame and edges

　　机柜的边框、棱角以及任何可触及的地方，不能有毛刺、尖锐棱边等可能对操作者或线缆造成损坏的可能性。在装配时，可能产生机械割刮伤的地方有：整机机柜的内外边框，贴板名条棱边，插框、部件着手的地方，电缆走线的走线槽或走线条以及靠近走线的棱边，电缆进出线的进出线口等。我司柜体结构设计时考虑充分倒圆，或者增加卷边以及使用喷砂等去毛刺措施。出线孔光滑，经充分倒圆或者采用翻边的形式或者套防护套，以保证走线及维护操作。

　　The frame, edges, and any accessible areas of the cabinet must not have burrs, sharp edges, or any other potential damage to the operator or cables. During assembly, there may be mechanical cuts and scratches on the inner and outer frames of the machine cabinet, the edges of the nameplates, the places where the frames and components are handled, the cable trays or lines for cable routing, and the edges near the routing, as well as the cable entry and exit ports.
