Description

  TECHNICAL FIELD The present invention relates to a cubicle equipped with a wireless base station and an integrated panel for a communication base station having a plurality of auxiliary devices attached to the wireless equipment with a power line connected therein as a communication base station installed outdoors. .

Conventionally, as a communication base station, a cubicle in which auxiliary equipment such as a radio and a battery is accommodated is installed outdoors (see, for example, Patent Document 1).
Generally, in a cubicle in which a wireless device is housed in this way, lightning protection measures are required to protect multiple auxiliary devices attached to the wireless device from lightning surges, such as power supply equipment that supplies operating power to the wireless device. ing. As a countermeasure against lightning, it is generally known that an arrester (lightning arrester) is inserted in the power line in order to prevent the incidental equipment that is vulnerable to lightning surges from being affected by lightning as much as possible (for example, patents). Reference 2).
However, although arresters are effective against induced lightning that penetrates each phase of the power line, some of the lightning voltage may penetrate into the electronic equipment, and the protection function is not always sufficient. There was a problem that was not. For this reason, it is known to install a lightning-proof transformer that can realize a higher protection function than the arrester.
