Description

  The present invention relates to a cubicle having a function of communicating operation information of electrical equipment with the outside.

  2. Description of the Related Art Conventionally, a cubicle in which a transmission / reception unit is installed inside a housing is known in order to wirelessly communicate operation information of electrical equipment with the outside. In this type of cubicle, the casing is formed of a metal plate to protect internal devices, so that radio waves may be shielded by the casing and hinder communication. Therefore, a cubicle has been proposed in which an antenna for relaying radio waves is provided outside the housing.

  For example, in Patent Document 1, in a cubicle 51 as shown in FIG. 9, a wireless device (not shown) is installed inside a housing 52, and a support pillar integrated aerial wire 53 is erected outside the housing 52. A technique is described in which 53 communication lines (feeder lines) are connected to a wireless device through a communication port (not shown) of the housing 52.
