になるといった問題点を有していた。With such a conventional configuration as described above, particularly in the case of a time-slot electric power charge system in which the power charges for midnight and daytime are measured from individual watt-hour meters, the power consumption for nighttime power and daytime power is reduced. Display the calibration separately. When a day / night wattmeter with a built-in timer function for separately measuring is connected, if the set time of a device with a timer function, such as an electric water heater with a timer in the circuit, shifts even slightly, it is weighed. There may be cases where the electricity charges do not reflect the actual usage. In particular, even if electricity was actually used during the midnight hours, it was expensive because the timer for controlling energization was out of time.If calculated using a daytime electricity charge system, it would be expensive without the user's awareness. There was a problem that it means that a large amount of electric power was used.

グを昼夜電力量計２からタイマー６へ伝達している。In FIG. 1, reference numeral 1 is a power supply wire, and a day / night watt-hour meter 2 is connected after the inlet of the power supply wire 1. The day / night power meter has a timer function capable of measuring the power consumption of an electric appliance by dividing it into late-night power and daytime power. One of them is connected to an individual daylight electric appliance 12 via an indoor wiring board 8 in the room. On the other hand, the wiring breaker 3, the switch 4 (collectively referred to as a relay hereinafter), the timer 6, (the relay 4 and the timer 6 are code 5).
The electric appliance 7 (hereinafter, referred to as an electric water heater) corresponding to the late-night charge is connected via the electric appliances 7). Further, the timer 6 and the day / night watt-hour meter 2 for measuring electric power are connected by a signal line 13, and the timing of day / night calibration is transmitted from the day / night watt-hour meter 2 to the timer 6.

Day and night electricity meter 2
Has a built-in timer function.
When it is 1:00), it will be automatically converted to late-night power and will be subject to inexpensive power charges. Therefore, even the daytime electric appliances 12 are used at this time, and they are calibrated at the late-night power charge. In addition, the same applies to energization during the daytime hours, no matter how much the electric water heater 7 is used, as with the daytime electric light appliance 12,
It is calibrated as an expensive daytime electricity charge.

かつ、正確に検量することができる。As described above, according to the midnight power switching apparatus of the present invention, the midnight power charge time zone and other time zones are calibrated by dividing the power consumed by the electric appliance into the midnight power and the daytime power. Since it is designed to synchronize with the time of the watt-hour meter with a built-in timer function, the power is turned on by the same power line, and the power is turned on for a preset time period under the control of a device with a timer function. -In addition to turning off, you can turn on and off the power in synchronization with the two time zones of the watt hour meter, so the power consumption of the device that matches the actual usage and has a late-night power rate contract,
It is possible to accurately and individually calibrate the amount of power consumed by the daytime electric power charge during the daytime.
