Benefits of technology

Electric power equipment of the present invention includes a main body case having an accommodation space for power supply element and a fire-extinguishing agent discharge space; and a plurality of power supply elements provided in the accommodation space for power supply element of the main body case. The fire-extinguishing agent discharge space has a fire-extinguishing agent spray space for spraying a fire-extinguishing agent to the plurality of power supply elements, and a fire-extinguishing agent supply space for supplying the fire-extinguishing agent to the fire-extinguishing agent spray space. A plurality of fire-extinguishing agent spray holes are provided in a first wall which separates the fire-extinguishing agent spray space from the accommodation space for power supply element. A plurality of fire-extinguishing agent supply holes are provided in a second wall which separates the fire-extinguishing agent spray space from the fire-extinguishing agent supply space. A fire-extinguishing agent tank is coupled to the fire-extinguishing agent supply space via a shutoff valve. Thus, the size of the electric power equipment can be reduced.
As described in the present invention, since the fire-extinguishing agent is sprayed not from a plurality of nozzles but from a plurality of fire-extinguishing agent spray holes provided in the first wall, a plurality of nozzles and shutoff valves are not required. As a result, the size of the electric power equipment can be considerably reduced.
Furthermore, the electronic device of the present invention employs the above-mentioned electric power equipment as a power source. Thus, the safety of the electronic device to be used can be enhanced.
Furthermore, power supply element inspection equipment of the present invention employs the above-mentioned electric power equipment as inspection equipment of a power supply element. Thus, the safety of the power supply element inspection equipment can be enhanced.

Problems solved by technology

The above-mentioned conventional example has a problem that the size of the electric power equipment becomes larger.
The use of the plurality of nozzles and shutoff valves in this way causes the size of the electric power equipment to increase.
