JPH11111149A - Power demand supervising breaker - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable alerting when a current reaches an arbitrarily set current and to prevent a loss in advance through taking action such as controlling a redundant load before a breaker is down by imparting a function capable of supervising a power use state from the outside for a main circuit breaker, earth leakage breaker or the like. SOLUTION: A current detecting mechanism is incorporated in an ampere breaker 1, and a alerting buzzer 2 and an LED 3 corresponding to a use current display 4 and current setting control knob 5 are provided. A current use quantity can be grasped by the LED three-point lighting state, and if a rated current is exceeded, an alerting buzzer sounds to indicate alerting before the ampere breaker 1 is disconnected. For use for energy saving, the alert setting control knob 5 is set to an arbitrary current value lower than the rated current value, so as to alert even if the current does not reach the rated current. Thereby, energy saving and effective operation of electric equipment are attained simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power monitoring device.

[0002]

2. Description of the Related Art A conventional amp breaker detects an overcurrent, a short circuit, a short circuit, or the like, and cuts off a load circuit when the rated current is exceeded.

[0003]

In the case of using a conventional breaker, the user cannot monitor the amount of power used, and in the case of an overcurrent or the like, the load suddenly becomes a blackout, and a personal computer or a load is connected to the load. If there was a connection such as a cash register, a large loss was incurred.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made to prevent the loss thereof, and is characterized in that a function capable of externally monitoring the use state of electric power is provided to a breaker, an earth leakage breaker and the like of a main circuit. It is. Further, an alarm can be issued when the current reaches an arbitrarily set current, so that it is possible to prevent loss by taking measures such as controlling an extra load before the breaker falls. At present, energy saving and efficient operation of electric equipment can be achieved at the same time by installing the product of the present invention for the main switch contract contracted by the breaker ampere capacity of most ordinary households.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is characterized in that a breaker, a ground fault circuit breaker, and the like of a main circuit are provided with a function capable of externally monitoring the use state of electric power. In addition, an alarm can be issued when the current reaches an arbitrarily set current, so the extra load is controlled before the breaker falls.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the ampere breaker with 4 current detection mechanisms and 2
The alarm buzzer is built in. The current amount of current consumption can be grasped from the LED lighting status of 3, and if the rated current is exceeded, the built-in buzzer of 2 is sounded and an alarm is issued before the breaker shuts off. When using as energy saving, set the 5 alarm setting adjustment knob to an arbitrary current value lower than the rated current value, and you can output an alarm without reaching the breaking current. By controlling, power consumption can be reduced. FIG.
Is an installation example where the earth leakage breaker has the same function as above.

[0007]

According to the present invention, by installing the product of the present invention with the above structure, energy saving and efficient operation of electric equipment can be simultaneously performed. In addition to the breaker built-in type as shown in FIG. 1, it can be built in a ground fault circuit breaker as shown in FIG.
