山东无尘车间如何合理设计配电柜内部构造

来源:http://www.henganjh.cn │ 发表时间:2019-08-12 

  如何合理设计山东无尘车间配电柜的内部结构?它包括:
  How to rationally design the internal structure of distribution cabinet in Shandong dust-free workshop? It includes:
  (1)干燥剂箱放置合理
  (1) Reasonable placement of desiccant box
  配电柜内的空气在电气设备运行后形成一定的流场。对于被动式防潮配电柜,如果其内部干燥箱放置不当,会影响干燥剂的除湿效率。配电柜底部水分相对集中,干燥剂箱应安装在气流速度较小且相对集中的底部。
  The air in the distribution cabinet forms a certain flow field after the operation of electrical equipment. For passive moisture-proof distribution cabinet, if the inner drying box is improperly placed, the dehumidification efficiency of desiccant will be affected. The water at the bottom of the distribution cabinet is relatively concentrated, and the desiccant cabinet should be installed at the bottom of the cabinet with relatively low air velocity and concentration.

  (2)联锁机构优化
  (2) Interlocking mechanism optimization
  配电柜防潮技术介绍了被动式防潮配电柜内的干燥箱。箱内放置的干燥剂可以去除由于无源防潮配电柜的开启/关闭而进入配电柜的水分。考虑到门打开时干燥剂与空气直接接触会导致干燥剂快速失效,采用干燥剂箱盖与门联锁结构。由于配电柜门板上下跨度较大,仅在箱底安装联锁装置就会使箱门变形,造成密封失效。因此,在设计柜门时,应适当加大柜门的按压力度和柜门的摆放位置,保持柜门整体受力平衡,减少柜门的变形。

  The moisture-proof technology of distribution cabinet introduces the drying box in passive moisture-proof distribution cabinet. The desiccant placed in the box can remove the water entering the distribution cabinet due to the opening/closing of the passive moisture-proof distribution cabinet. Considering that the direct contact between desiccant and air will lead to the rapid failure of desiccant when the door opens, the desiccant box cover and door interlocking structure are adopted. Because the upper and lower span of the distribution cabinet door panel is large, only installing interlocking device at the bottom of the cabinet will cause the deformation of the cabinet door, resulting in sealing failure. Therefore, in the design of cabinet doors, the pressure of cabinet doors and the position of cabinet doors should be increased appropriately, so as to maintain the overall force balance of cabinet doors and reduce the deformation of cabinet doors.
  普通电气设备在高湿度环境下的电气性能和可靠性急剧下降,容易引起电气故障。只有对电气设备进行有效的防潮保护,才能减少或消除这些故障。因此,研究电气设备的防潮技术和防潮配电装置的设计制造方法,对提高我国电力行业的施工和维修管理水平,提高使用效率具有重要的现实意义和实用价值。
  The electrical performance and reliability of ordinary electrical equipment in high humidity environment are declining sharply, which is easy to cause electrical failure. Only by effective moistureproof protection of electrical equipment can these faults be reduced or eliminated. Therefore, the research on the moistureproof technology of electrical equipment and the design and manufacture method of moistureproof distribution device has important practical significance and practical value for improving the construction, maintenance and management level of our country's electric power industry and the use efficiency.
