Description

  The present invention relates to a humidity control member installed in, for example, an electric / electronic device storage box in which a distribution board, an operation panel, etc. are stored, and more specifically, a humidity control member having a plurality of humidity control plates and its humidity control The present invention relates to a humidity control plate holder used for a member.

  A box with a distribution board that divides high-voltage power supplied from the power plant, a box with an operation panel for operating power equipment, and a small box with communication equipment In addition, there are various electric / electronic device storage boxes such as boxes in which electronic parts for various machine controls are stored. In order to protect electric equipment and electronic equipment, when power is supplied, the temperature in the box is relatively high and the relative humidity is kept relatively low.

  However, when the supply of power is stopped, the temperature in the box rapidly decreases. For this reason, the relative humidity in the box increases rapidly. As a result, dew condensation may occur on the electrical and electronic devices in the box, or insulation failure and leakage may occur. Such a problem is particularly likely to occur in a box installed outdoors. According to observation records from the Japan Meteorological Agency, the temperature dropped by about 20 ° C in one hour and by about 22 ° C in day and night. In a box installed outdoors, the temperature inside the box suddenly changes due to a change in the external environment, and the relative humidity sometimes changes abruptly. Conventionally, in order to solve such a problem, a humidity control material is installed in the box.

  The humidity conditioning material is configured using a material that can adsorb water vapor even at a relative humidity of 100% or less, for example. The humidity conditioner adsorbs water vapor or releases the adsorbed water according to changes in the external environment. Thereby, the change in the relative humidity of the surroundings can be reduced.

  As an example of the humidity control material as described above, the following Patent Document 1 describes a method of suspending a sheet-type humidity control material from a box door as a method for mounting a humidity control material made of a water-absorbing polymer in a box. Has been.

  Furthermore, since a humidity control material made of a water-absorbing polymer is used, there is a disadvantage that the shape changes with the passage of time, and phenomena such as blistering and collapse have also occurred.

Further, Patent Document 2 discloses a laminated body of humidity control plates in which a plurality of humidity control plates are stacked at intervals. Here, the plurality of humidity control plates are stacked by inserting screws into screw holes formed in the squares of the plurality of humidity control plates.
