Then, the communication unit CPU 84 transmits the power usage data obtained from the smart meter 7 to the communication measurement unit 4.

Here, power usage information transmitted from the communication measurement unit 4 to the HEMS device 11 and the like will be described. The communication measurement unit CPU 45 calculates the power consumption data for the entire dwelling unit based on the current information of the main current sensor 13, while communicating with the smart meter communication unit 8 and using the power consumption information output by the smart meter 7. Obtain.
Since the power usage information obtained from the smart meter 7 is reference data (correct data) used by the power supplier, the data based on the main current sensor 13 is corrected with the reference data and the use of each branch electric circuit. The power data is also corrected and the corrected data is transmitted to the outside.
As a result, the communication measurement unit 4 obtains the power usage information of the entire dwelling unit from the smart meter 7 and corrects the power usage calculated based on the information from the current sensor. Can be obtained.

  The seismic isolation system configured as described above operates as follows in response to the occurrence of an earthquake. An earthquake occurs when commercial power is supplied and electric power is supplied to the electrical equipment in the dwelling unit. This earthquake is set in advance by the seismic intensity setting unit 33 or the like as a threshold for the earthquake-sensitive relay 3 to output an earthquake detection signal. If the seismic intensity is greater than or equal to the seismic intensity (for example, seismic intensity of 5 or less), the seismic relay 3 detects this and immediately outputs an earthquake detection signal from the external communication unit 38. Further, the buzzer 36a sounds and the LED 36b blinks. Then, the output earthquake detection signal is transmitted to the seismic communication unit 5.

  The seismic communication unit 5 receives the earthquake detection signal and transmits the earthquake occurrence information to the HEMS device 11, and sends an operation signal to the group of second breakers 2 b connected to the first output unit 53. Output and shut off. In addition, a cutoff signal is output from the second output unit 54 to the outlet unit 12 with a cutoff function via the outlet control unit 6. As a result, before the main breaker 1 is cut off, all the outlet units 12 having the cutoff function connected to the group of the second breakers 2b and the outlet control unit 6 are cut off.

  On the other hand, when a certain time (delay cut-off time) set in advance by the cut-off time setting unit 34 or the like has elapsed since the earthquake detection signal was output, the pseudo-fault leak output unit 35 outputs a pseudo leak. That is, the operation for generating a pseudo-leakage is started. As a result, the main breaker 1 is cut off, the main electric circuit M is cut off from the commercial power supply, and all branch electric circuits are cut off.

In this way, when an earthquake with a predetermined seismic intensity or higher occurs, all other electrical circuits are interrupted after a certain period of time, so it is possible to prevent the occurrence of energized fires, and the lighting, etc. when evacuating immediately disappears. It can be controlled so that there is no. When an earthquake occurs, the external HEMS device 11 is notified of the occurrence of the earthquake. Therefore, the earthquake information can be easily obtained without checking the state of the seismic relay 3, and the HEMS device 11 Since setting is possible, there is no need to operate the seismic relay 3 directly, and there is no need to connect a separate setting means.
Moreover, since the HEMS communication means is comprised by the seismic communication unit 5 that communicates with the seismic relay 3 and the communication measurement unit 4 that transmits power consumption information to the HEMS device 11, the seismic relay without providing a separate device. 3 and the HEMS device 11 can be communicated.
Furthermore, since some branch breakers 2 (second breakers 2b) immediately shut off when an earthquake occurs, it is possible to immediately shut off an electric stove or the like that is likely to cause a fire or the like due to the occurrence of an earthquake.
In addition, since the outlet unit 12 with a shut-off function shuts off immediately when an earthquake occurs, other electrical equipment connected to a common branch circuit is also turned off in conjunction with the electrical equipment that requires immediate shut-off operation. It is easy to solve the problem.
In addition, a plurality of outlet units 12 with a blocking function can be simultaneously cut off without changing the configuration of the seismic communication unit 5. Moreover, the HEMS apparatus 11 can grasp the seismic intensity of the earthquake, which is convenient.

In the above embodiment, the communication measurement unit 4 and the seismic communication unit 5 are separated from each other, but may be configured integrally. In addition, although the outlet control unit 6 that shuts down the outlet unit 12 with the blocking function is provided, when there are few outlet units with the blocking function to be installed, the outlet units 12 with the blocking function are connected in series, and one end is sensed. You may connect directly to the seismic communication unit 5.
Moreover, although the branch breaker 2 (second breaker 2b) and the outlet unit 12 with a blocking function are installed as devices that immediately shut off in response to the occurrence of an earthquake, only one of them may be used.
Further, the operation of shutting off the second branch breaker 2b is performed by the control of the seismic communication unit 5, but the shutting operation may be performed directly by the earthquake detection signal output from the seismic relay 3.
