Description

[Detailed description of the invention] ゛This invention relates to a power distribution circuit for power consumers that uses late-night power.◇ Power demand fluctuates greatly between day and night, and during the summer when the maximum power is consumed. If we take the daytime peak power as a standard, it will drop to about q or o in the middle of the night, and especially in urban areas it will drop to several 10%.
decreases to Additionally, in the summer, electricity costs are high due to the use of coolers, and electricity demand fluctuates widely throughout the year. Therefore, the power equipment must be enlarged. It is desired to reduce such power peaks so that power consumption is always averaged throughout the year.

On the other hand, from the perspective of electricity consumers such as individual consumers, - refrigerators that consume a lot of electricity throughout the year, air conditioners that consume a lot of electricity, washing machines, vacuum cleaners, color televisions, and various other lighting equipment are equipped. The current situation is that a large amount of power is consumed, τ11, and the power charges are high.

This invention was made in view of these points, and focuses on surplus late-night electricity, stores it in each electricity consumer using late-night electricity, and uses this storage battery as a power source for electrical equipment. By suppressing power peaks throughout the year,
The idea is to reduce power equipment by equalizing power consumption, and in addition to this, the above storage batteries are used only for electrical equipment that consumes a constant amount of power throughout the year. This will improve the efficiency of the storage power source equipment, reduce the burden on equipment costs, and, in combination with the use of late-night electricity, reduce electricity charges for consumers.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 7 indicates the first electrical equipment connected to each of the 5.5'15" ends of these branch lines, and the first electrical equipment 7 includes coolers, washing machines, electric kotatsu, etc. whose power consumption fluctuates greatly throughout the year. 8 is a late-night power line connected in parallel with the above-mentioned general power line 2 at the end of the service line 1, 9 is a tumbler switch provided on this late-night power line 8, and 10 is an integration value also provided on the late-night power line 8. Electricity IIT meter, 11
12 is a power supply device connected to the midnight power wiring 8 in parallel with this water heater 11; 13 is a breaker connected to the output end of this power supply device 12; , 14' are each of this breaker-1
These branch lines 14.
14' and 14' have fuses 15 and 15', respectively.
15" is the provision. 16 is these branch lines 14.14
1 with the second electrical equipment connected to the 14' and 14' ends, respectively.
．． This second electrical equipment 16 includes lighting equipment such as a refrigerator and electric lamps that consume constant power throughout the year. Next, the power supply device 12 has a charger 17, a storage battery 18, an inverter 19, and an AC filter connected in series as shown in FIG. It is connected to 19. A detector 22 is also connected to the storage battery 18, and when the storage capacity of the storage battery 18 decreases, the switch debris installed in the wiring connected to the input end of the power supply device 12 is removed from the general power wiring 2. It is closed.

The first electric device 7, whose power consumption fluctuates widely, is always supplied with power from the general power supply, but what about the power? l
``The second electrical equipment 16, which is stable throughout the year, uses late-night electricity exclusively.In other words, electricity is stored in the storage battery 18 using the charger 17 at night when late-night electricity is supplied, and this is transferred to the inverter. 19 and a father-flow filter to convert it into alternating current and supply it to the first electrical equipment 16.Therefore, the second electrical equipment 16 uses the power supply device 12 that stores late-night power as a power source, day or night. That is.

Moreover, in the above embodiment, if the storage capacity of the power supply device 12 is reduced, the switch is closed by the detector n, the storage battery 18 of the power supply device 12 is charged from the general electric power, and the power supply of the second electrical equipment 16 is switched on. It is designed to compensate.

In this way, in this invention, the power source of the second electrical equipment 16 such as a refrigerator, which consumes power relatively stably throughout the year, uses late-night electricity. As is clear from the breakdown table of household electricity consumption in Figure 3 (Agency for Natural Resources and Energy, 1981), household appliances account for approximately SO% of household electricity consumption. Therefore, by adopting the power distribution circuit of the present invention at each power demand floor, the YO cost of general power can be reduced, power peaks can be reduced, power consumption can be averaged throughout the year, and power equipment can be reduced. In addition, on the electricity demand floor,
As mentioned above, about half of the power consumption is covered by surplus late-night power, so even if other electrical equipment is used with regular power, the power supply system is inexpensive. Moreover, in this invention, since the power supply device 12 including the storage battery 18 is connected to the first electrical equipment 16 such as a refrigerator JIE that is used constantly throughout the year, the load factor of the power supply device 12 can be stabilized and it can be used efficiently. Therefore, the daily usage fee relative to the equipment cost of the power supply device 12 is also reduced.

As described above, if the power distribution circuit of the present invention is used, power can be supplied by averaging it throughout the year without unnecessarily increasing the power supply equipment, and power charges can be lowered on the power consumer side. It is clear that this will bring about good results.
