Home Electric Power Monitoring & Watch

The present invention relates to a home electric power user monitoring and monitoring device, and more specifically, by adding a simple monitoring device to a distribution board that is supplying electric power to a home, the energy consumption can be displayed to a power user by displaying a percentage of power consumption. It is a device to prevent accidents due to power usage.

In general, home or apartment offices are supplied with low-voltage power for household single-phase or three-phase, and the integrated power meter indicating the amount of power used is installed outside or invisible, which is inappropriate to know the amount of power used. Therefore, even if you use a lot of power or less power is not the current situation is not easily determined.

Therefore, no matter how much the printed material of the limit-off campaign for energy saving campaign was attached, the effect was questioned.

Looking at this conventional technology, safety and convenience were added by installing an earth leakage breaker (ELB) and a no-fuse brake (NFB) equipped with current electronic devices in a toad house in the past. Not only do they know how much load is under load, but they are developing nationally-off campaigns, but they have no doubt about their utility.

In addition, due to corrosion of electric wires due to long use of electric power, many people live in short circuits or when the power supply is turned on, and they live in a closet or other places where the power is turned on. have.

However, in the case of luxury cars, there is a function that shows the real-time fuel consumption and heavy fuel consumption during acceleration, so that the driver can restrain rapid start and acceleration and maintain fuel economy, thereby reducing fuel economy. Despite the national campaign to save home and office electricity, the reality of the energy-saving movement was limited.

In addition, the excessive use of power caused a serious disaster such as a fire when the safety device was not operated.

The present invention was devised to solve the above problems, and displays the amount of power used in the home or office as a percentage (%) and installs a monitor device in a place where it can be easily seen so that the power consumption can be easily understood. When using the power exceeding capacity, it can generate a warning sound by the lamp or bell. Also, by using this output, it can provide the function to cut off the power so that it can be applied to home automation. do.

In order to achieve the above object, the present invention installs a current transformer (CT) which is a current sensing sensor on one line of household power inlet, connects the detected signal to the connection line of the main body, and the main body has AC 110 volt or AC 220 volt of the inlet wire. If the power is supplied, set the initially designed power capacity to 100% or assume the user's 100% arbitrarily, and then use the current power as a numerical value or bar on the analog instrument or digital display. Should be displayed.

In addition, the power lamp is attached to the normally ON contact of the relay (contact type, contactless type included) inside the main body to indicate that power is being supplied, and the constant OFF contact is turned on when an overload occurs above the set value. Alternatively, a bell can be signaled to alert you to the danger of excessive power use.

According to the device of the present invention, the power capacity can be set to 100% or the user can set the 100% range arbitrarily so that the power usage can be known. In addition, it is a relatively simple configuration that not only saves the energy required by the state, but also makes it easy for the user to know that the power consumption is large and small when using unknown or inefficient power equipment. Even devices that are not used will be able to tell you to turn off the power by looking at the usage figures.

Hereinafter, the home power user monitoring and monitoring device of the present invention will be described in detail with reference to the accompanying drawings.

1 is a main body of the present invention, the control board is mounted on the main body, and an input terminal for applying power is an operating power terminal for connecting an AC 110 volt or an AC 220 volt (①②③). If you select and turn on the power, the main unit will be in operation and then input and adjust the sensor.

Figure 2 is a sensor for detecting the power line current (A) of the present invention is a current transformer (CT) of the circular or square shape. The output terminals (⑦a, ⑧b) of the device is connected to the main body.

Next, the CT is connected to the current transformer CT input terminal ⑦⑧ of the main body device of FIG. 1 to sense the current flowing through the power supply line.

3 is a display device of the present invention, which is displayed as a percentage and serves as a monitor. Fig. 3-1 is an analog display type instrument and Fig. 3-2 is an LED type or LCD type digital display device. By connecting the input terminal (⑨a) of the display device to the output terminal of the main body (⑨),

The main body enters the current transformer CT, which is a sensor for sensing a current, and outputs an indicator, which leads to an operating state, and the power lamp 14L of the main body is turned on to show that power is supplied and ready for operation.

Next, the digital output device (④⑤⑥) of the main body is an output terminal of a relay or a contactless relay.The output terminal common terminal (⑤) is always ON terminal (④) and is always OFF terminal (⑥). It can be configured as a lamp or bell, so that the user can freely install additional devices according to the user's request.

Next, it should be input to perform the important task of the present invention through the adjusting device of the body.

1 Turn the volume of the total current measurement 11 of the main body to turn on the entire power supply of the user and to turn it ON so that the capacity of the power equipment installed in the distribution box is adjusted to the percentage number 100% of the design indicator. This percentage of 100% is not easy for users to adjust arbitrarily, and the place where the product is installed is notified to the user unconditionally when the power capacity is exceeded, thereby preventing accidents caused by excessive current use.

However, it is usually recommended to set 70-80% of the total capacity as a method of saving the power, and the% adjustment volume 11-1 can adjust the value of the total amperometric volume 11 arbitrarily determined by the user to 100%. It was made.

Therefore, if the capacity of the entire facility is assumed and defined, even if it is 100 amperes (A) of current capacity, it can be displayed as 100% on the user's monitor.

Next, the starting current time setting (12) is the volume. This may exceed 100% set by the user due to the instantaneous starting load when the power is suddenly turned on and the power is turned on. In consideration of returning to the load, the user can set 0 to 30 seconds after setting arbitrarily, and the range of this is enlarged when the power of the air conditioner or similar device with a large starting load is turned on.

Next, the shock current detection function (13). This means that when a large load power device is used suddenly while using electricity, the possibility that an alarm will be exceeded and the digital output is always turned OFF is turned on. In view of this, the user can arbitrarily adjust the time between 0 and 5 seconds. Here, the operation time is shortened so that the digital output or alarm can be operated quickly when a shock current occurs, which is a function to prepare for an electric shock lamp accident in anticipation of a short-circuit or a sudden power failure.

Next, a test button for testing the operation of the design in advance.

The operation test button 17S is a return button 18R. When the operation test button is pressed, the operation state is reached in excess of the usage amount of 100% or more, so that the function set by the user can be known. It is to return the original state.

And, although not shown, the main body and the adjusting device of the invention can be integrated or remote control type, it is natural that the circuit control unit, the adjusting knob, the tooth device and the like for operating them.

It will now be described in detail the operation of the home power user monitoring monitoring device of the present invention configured as described above.

The main body of FIG. 1 has an electronic circuit unit installed in a distribution box, and is an apparatus for adjusting, setting, and controlling a function. The apparatus includes an input unit of a current sensing device, a monitoring output unit for judging and displaying a state, and a digital output unit. This is a cross-sectional view of a device having an output unit that can be arbitrarily applied by a user.

The sensor unit of FIG. 2 is a device capable of detecting the current amount of the conductive wire when the power is turned on as the current transformer CT and penetrates the electric current flowing wire.

3 is a device in which a power factor, which is not a unit of watts or amperes, which normally measures a load of an electric device, is applied and simply displays it linearly or numerically.

Now, the user attaches this device to the distribution board or switchboard, and is using excessive electricity through the visual device that displays the amount of electricity he is using as a percentage through the monitoring device. You will be able to see if you can use additional power, or if you do not know the electricity you are using.

Furthermore, not only during normal power usage, it is also possible to easily determine whether only essential electricity (refrigerator, etc.) is being used when finishing work such as an office or going out from home.

As a result, anyone pursuing the present invention can easily know the power consumption, and it is possible to suppress the use of power and electronic devices that consume excessive power as well as determine whether the power equipment exceeds the load. Turning off the power and electronic devices can reduce the energy savings, and this indicator is installed in a place where it can be easily seen, which makes it an important instrument for safe energy use as well as the awareness of energy saving at all times.
