Description

  The present invention can be installed outdoors, such as power in homes such as ordinary homes and offices, safety grounds for communication, CATV, etc. For example, various home appliances and various types of information communication equipment are connected at one point The present invention relates to a grounding storage cabinet in which the grounding of devices is made common.

Conventionally, it is known that strong electromagnetic fields generated by lightning strikes nearby power lines and communication lines, and electronic devices connected to both power lines and communication lines instantaneously flow large currents due to lightning surges. As a result of failure and damage, information lines that are diversified, for example, information lines such as optical fibers in addition to telephones and CATV can be drawn in, and ground lines for signal wiring and power wiring to the arrester at different points. So that it would not adversely affect various devices during lightning strikes.
However, in homes, there is no protective device including a lightning arrester for power distribution, and for common installation, it is necessary to install a protective device, and the connection terminals and installation location must be considered in relation to the grounding bar. Must-have.
In particular, as control cabinet boxes, electromagnetic shield boxes, and control boxes are commercially available, power cabinets and communication devices such as communication protectors and CATV protectors are collectively stored in the housing. Various types of cabinets have been proposed and used.

A lightning protection switchboard is a lightning protection switchboard that is equipped with a lightning arrester arrester that is grounded by connecting an input line to a single housing. It is described that an arrester having a different type from a signal arrester connected to a signal wiring such as a wire is housed in a housing (see Patent Document 1).
JP-A-10-117409

This type of arrester with different types of arresters installed inside the housing enables high-power wiring and signal wiring to be connected to the arrester at the same point, improving workability and electromagnetic induction, etc. Although it is now possible to eliminate the influence of lightning current generated indirectly by the cable, the high-voltage wiring and the signal wiring are arranged side by side in the housing. When maintenance and work such as inspection of equipment, inspection of equipment quality, inspection, etc. are necessary, we do not want workers and residents to handle the integrated power meter of power wiring system etc. The equipment was ready to be inspected and worked on site, and there was a problem with the maintenance of the equipment.
In addition, this lightning switchboard is mixed with power equipment including power line terminals to enable connection or branch connection of power lines. In addition, there is a drawback of lack of safety due to fear of electric shock due to unsatisfactory work or careless work. In addition to being inconvenient in handling, there is a risk of hindering maintenance of the safety of the equipment.

The present invention intends to eliminate these conventional drawbacks and inconveniences, and it is possible to clearly separate power equipment and information communication equipment by attaching the equipment to the partition plate provided in the housing, and it is compact and safe. It is used as a high-capacity grounding storage box, and can be installed easily, and after removing the cover during inspection and repair, a sufficient work space can be secured, and power equipment and communication equipment can be clearly separated. Therefore, it is easy to handle without worrying about erroneous work such as incorrect wiring and incorrect operation, and it is safe to carry out and to shorten and simplify the handling time.
Furthermore, in the present invention, considering that the workers are different when setting the power devices and the information communication devices, the power devices and the information communication devices are separately installed. Therefore, even if work or maintenance becomes necessary, inspection and maintenance of the storage equipment can be performed easily without causing erroneous work.
