山东无尘车间电气设备配电柜防潮方案

来源:http://www.henganjh.cn │ 发表时间:2019-08-19 

  在介绍山东无尘车间的基础上,提出了电气设备配电柜防潮方案
  On the basis of introducing the dust-free workshop in Shandong Province, the moistureproof scheme of electric equipment distribution cabinet is put forward.
  正常情况下,电气设备主要集中在配电柜中,做好配电柜空间和箱体的防潮工作,可以解决配电设备的防潮问题。
  Normally, electrical equipment is mainly concentrated in distribution cabinet. Moisture-proof work of distribution cabinet space and cabinet can solve the problem of moisture-proof of distribution equipment.
  (1)箱体防腐。配电柜本体直接暴露在高湿、易腐蚀的环境中,应采取可靠的防腐措施。
  (1) Anti-corrosion of the box. The main body of distribution cabinet is directly exposed to high humidity and corrosive environment. Reliable anti-corrosion measures should be taken.
  (2)配电柜完全密封,开合后采用干燥剂吸收进入柜内的水分,为柜内所有电气设备提供干燥的环境。
  (2) Distribution cabinet is completely sealed. After opening and closing, desiccant is used to absorb moisture into the cabinet to provide a dry environment for all electrical equipment in the cabinet.
  (3)选用无腐蚀性吸湿材料。
  (3) Selection of non-corrosive moisture absorption materials.

  (4)具有间歇工作时形成的内外压差保护措施。从关闭状态当电气配电箱到工作状态,或在炎热和潮湿的季节,昼夜温差大,密封的内部和外部的内阁将形成一个更大的压差,如果不保护,内阁密封将受到压力的变化影响,加速老化甚至损坏。
  (4) Internal and external differential pressure protection measures formed by intermittent work. From the closed state to the working state, or in the hot and humid season, the temperature difference between day and night is large, the internal and external cabinets of the seal will form a greater pressure difference. If not protected, the cabinet seal will be affected by the change of pressure, accelerating aging and even damage.
  (5)配电柜柜门板通常需要许多灯,按钮开关,必须考虑自己的防潮和密封的孔,所以考虑采用双柜门板结构,内光和按钮开关柜门,柜门外,采用严格的密封措施,确保柜门密封。
  (5) Distribution cabinet door panels usually require many lights, button switches, must consider their own moisture-proof and sealing holes, so consider the use of double cabinet door panel structure, light and button switch cabinet doors, cabinet doors, using strict sealing measures to ensure the closure of cabinet doors.
  (6)配电柜的进、出口电缆及电线孔应密封。从理论上讲,配电柜的相对湿度还没有达到100%,不会发生冷凝现象。然而,在实际配电柜中,由于配电柜内部电气设备的分布和布置不能与计算模型完全相同,所以电气设备之间总是会有一定的间隙。此外,由于生产过程中,其热量也会存在一定程度的不均匀性。在设备反复运行过程中,如果不及时采取相应的措施,局部水分的相对浓度会导致凝结。因此,配电柜的内部结构应合理设计。
  (6) The inlet and outlet cables and wire holes of the distribution cabinet shall be sealed. In theory, the relative humidity of distribution cabinet has not reached 100%, and condensation will not occur. However, in the actual distribution cabinet, because the distribution and layout of the electrical equipment inside the distribution cabinet can not be exactly the same as the calculation model, there will always be a certain gap between the electrical equipment. In addition, due to the production process, its heat will also have a certain degree of non-uniformity. In the process of repeated operation of equipment, if appropriate measures are not taken in time, the relative concentration of local moisture will lead to condensation. Therefore, the internal structure of distribution cabinet should be reasonably designed.
