| ①操作方便。元器件在操作时，不应受到空间的防碍，不应有触及带电体的可 能。 (1) Easy to operate. Components in operation should not be hindered by space, there should be no possibility of touching charged bodies. ②维修容易。能够较方便地更换元器件及维修连线。 (2) Easy maintenance. It can easily replace components and repair wiring. ③各种电气元件和装置的电气间隙、爬电距离应符合4.4 条的规定。保证一、二次线的安装距离。 (3) Electrical clearance and creepage distance of various electrical components and devices shall comply with the provisions of Article 4.4. Guarantee the installation distance of primary and secondary lines. 1) 组装所用紧固件及金属零部件均应有防护层，对螺钉过孔、边缘及表面的毛刺、尖锋应打磨平整后再涂敷导电膏。 1) All fasteners and metal parts used for assembly shall have protective layer. The burrs and sharp edges of screw holes, edges and surfaces shall be polished and smoothed before being coated with conductive paste. 2) 对于螺栓的紧固应选择适当的工具，不得破坏紧固件的防护层，并注意相应的扭距。 2) For bolt fastening, appropriate tools should be selected, the protective layer of fasteners should not be destroyed, and the corresponding torsion should be paid attention to. 3) 主回路上面的元器件，一般电抗器，变压器需要接地，断路器不需要接地，下图中为电抗器接地。 3) Components above the main circuit, general reactor, transformer need to be grounded, circuit breaker does not need to be grounded, the following figure is the reactor grounded. 4) 对于发热元件 (例如管形电阻、散热片等) 的安装应考虑其散热情况，安装距离应符合元件规定。额定功率为75W 及以上的管形电阻器应横装，不得垂直地面竖向安装。 4) For the installation of heating elements (such as tubular resistors, radiators, etc.), the heat dissipation should be considered, and the installation distance should be in accordance with the requirements of the elements. Tube resistors rated at 75W or above shall be installed horizontally and not vertically on the ground. 5) 所有电器元件及附件，均应固定安装在支架或底板上，不得悬吊在电器及连线上。 5) All electrical components and accessories shall be fixed on the bracket or floor, and shall not be suspended on the electrical appliances and connections. 6) 接线面每个元件的附近有标牌，标注应与图纸相符。除元件本身附有供填写的 标志牌外，标志牌不得固定在元件本体上。 6) There are signs near each element on the wiring surface, and the marks should be in accordance with the drawings. Except that the component itself has a tag for filling in, the tag may not be fixed on the component body. 7) 标号应完整、清晰、牢固。标号粘贴位置应明确、醒目。 7) The label should be complete, clear and firm. The label pasting position should be clear and eye-catching. 8) 安装于面板、门板上的元件、其标号应粘贴于面板及门板背面元件下方，如下方无位置时可贴于左方，但粘贴位置尽可能一致。 8) Components mounted on the panel and door panel and their labels should be pasted under the panel and the back of the door panel. If there is no position below, they should be pasted on the left, but the pasting position should be as consistent as possible. 9) 保护接地连续性 9) Protection Grounding Continuity 保护接地连续性利用有效接线来保证。 Protective grounding continuity is guaranteed by effective wiring. 柜内任意两个金属部件通过螺钉连接时如有绝缘层均应采用相应规格的接地垫圈并注意将垫圈齿面接触零部件表面（红圈处），或者破坏绝缘层。 When any two metal parts in the cabinet are connected by screw, if there is insulation layer, the www.langfangbanjia.cn www.diandongmenl.cn www.yanglaoyuans.cn www.hengshuibanjia.cnwww.dianjiaojii.cnwww.guanjiaojii.cncorresponding specifications of grounding washers should be adopted, and attention should be paid to contact the surface of the parts (red ring) of the washer teeth, or damage the insulation layer. 门上的接地处（红圈处）要加“抓垫”，防止因为油漆的问题而接触不好，而且连接线尽量短。 The grounding (red ring) on the door should be padded to prevent poor contact due to paint problems, and the connection line should be as short as possible. 10) 安装因振动易损坏的元件时，应在元件和安装板之间加装橡胶垫减震。 10) When installing components which are easily damaged by vibration, rubber cushion should be installed between the components and the installation plate to reduce vibration. 11) 对于有操作手柄的元件应将其调整到位，不得有卡阻现象。将母线、元件上预留给顾客接线用得螺栓拧紧。 11) Components with operating handles should be adjusted in place without obstruction. Tighten the bolts reserved for customers on buses and components. |
