2. Description of the Related Art FIG. 6 shows outline drawings of a conventional power receiving and transforming board and a generator board. In FIG. 6, reference numeral 51 is a power receiving and transforming board. 52 is a generator panel. In an emergency when the power receiving and transforming board 51 cannot perform its function due to a fire or the like, the power generator in the power generator panel 52 operates to supply electricity to the emergency load instead of the power receiving and transforming equipment.

The power generator and the power receiving and transforming equipment are housed in separate cubicles and installed on independent foundations.

[0004]

However, in the above-mentioned conventional configuration, since the foundation of the generator board 52 and the foundation of the power receiving and transforming board 51 are separately prepared, the foundation work, the on-site wiring work and the on-site work such as trial run adjustment are performed. There was a problem that the cost of the whole electric equipment including it became high. Further, with the conventional configuration, it is difficult to secure an evacuation route on the installed site, and there is also a problem in terms of aesthetics.

In order to achieve this object, the cubicle-integrated power supply equipment of the present invention serves to secure a space for maintenance work between the power generation equipment and the power receiving and transforming equipment, and also serves as a maintenance board. A natural ventilation system is adopted in which an intake port is provided on the front or lower part of the rear surface of the maintenance panel, and an exhaust port is also provided on the rear or upper part of the front surface. An inspection door will be installed on the partition board of the maintenance board, and a box-type heat shield board will be installed. A heat insulating material is provided on at least one of the joint between the power receiving substation panel and the maintenance panel and the joint between the maintenance panel and the generator panel.

Further, since a rise in temperature inside the generator, in particular, an increase in engine intake air temperature lowers the generator output, a local heat absorbing device is provided which operates when the temperature near the engine intake port exceeds a certain value.

Furthermore, if the noise reduction value required using some cubicle body, at least one reducing noise values among the panel assembly of the intake silencer or an exhaust muffler.

In the case of the cubicle-integrated power supply facility as shown in FIG. 1, there is only one foundation. Therefore, it is possible to reduce the time required for on-site work such as foundation work, on-site wiring work, and trial run adjustment, and it is possible to reduce the cost of the entire electric equipment. It also improves evacuation routes and aesthetics.

The operation when a fire or the like occurs in the power receiving and transforming equipment will be described below. The heat on the power receiving and transforming equipment side is blocked by the heat insulating material installed at the joint between the power receiving and transforming board 1 and the maintenance board 2 and the box-shaped heat shield plate installed on the partition plate 3.

In addition, since natural ventilation is provided by the heights of the lower intake port 6 and the upper exhaust port 7, the flow of air allows the heat generated by the fire of the substation to be dissipated. Heat is hard to be transmitted to 4.

Further, the heat effect on the generator board 4 is reduced by the heat insulating material installed at the joint between the maintenance board 2 and the generator board 4.

When the temperature near the engine inlet 8 of the power generator rises, the engine output decreases. The thermoswitch A11 that operates at the set temperature near the engine intake inlet 8 of the power generation device 4 becomes "closed" when the temperature exceeds the set temperature, and the battery power source 14 of the power generation device is supplied to both ends of the heat absorption device 13 composed of the semiconductor 12. The air in the vicinity of the engine intake inlet 8 is cooled by the heat absorption due to the Peltier effect of the semiconductor 12. The cooled air is supplied to the engine by the suction force of the engine itself. On the contrary,
In order to improve the startability of the engine at low temperatures, a thermoswitch B15 that is "closed" when the temperature is lower than a set temperature is provided, and a current is passed through the semiconductor 12 in the opposite direction to the heat absorption function, which is used as a heat generating device and engine auxiliary device It is also possible to do so.

The sound absorbing device is a panel assembly type in order to effectively use the space above the cubicle and the outer plate.
The sound absorbing device includes a top plate 16, a bottom frame 17, a bottom plate 18, and a front frame 1.
9, the rear surface 20 and the sound absorbing panel 21 are assembled by bolts. To reduce the noise of the intake air side of the inner and the sound absorbing material and a generator device with partitioned shape of the air passage in the sound-absorbing panel of the sound absorbing panel 21 of the bottom plate 18.

When the resistance of the air flow path becomes larger than the suction force of the engine itself of the power generator, the output of the engine is reduced, so that the sound absorbing panel 21 has a sufficient noise reduction amount.
To reduce the resistance of the air flow path. In addition, the resistance of the air passage has a margin, and if it is desired to increase the noise reduction amount, the number of the sound absorbing panels 21 is increased.

Although the cubicle integrated power generator is described in the present embodiment, it goes without saying that claims 6 and 7 can be applied to a power generator independent of the power receiving and transforming equipment.

[0024]

INDUSTRIAL APPLICABILITY As described above, the present invention is an integrated electric facility in which a power generator and a power receiving and transforming facility are installed in a cubicle, and includes on-site work such as foundation work, on-site wiring work and trial run adjustment. In addition to reducing the cost of the entire electrical equipment, it has advantages in securing evacuation routes and aesthetics, and is easy to maintain or has low noise type keys.
This is a cubicle- integrated power supply facility for the ubicle-integrated power supply facility, and the heat generated by the fire of the power receiving and transforming facility is less likely to be transferred to the power-generating facility so that the power-generating device operates reliably.

Further, even if the output of the power generator and the starting performance are improved by the heat absorbing and heat generating devices, and the output of the power generator housed in the generator panel is changed by the panel assembly type sound absorbing device,
Noise can be reduced without changing the external dimensions of the sound absorbing device.
