[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a switchboard equipped with a switch that can turn on and off electricity to various electric devices.

[0002]

[Prior Art]

 FIG. 6 shows a conventional switchboard, 1 is a switchboard, MS is a main switch, S₁  ~ S₈ Is a power supply switch for turning on and off the power supply to each of the displayed power supply targets.

[0003]

[Problems to be solved by the device]

 In many factories, in order to save electricity during the lunch break, it is instructed to turn off power to electrical equipment, including lighting, but the reality is that this is not easily done.

The present invention is intended to improve such a conventional problem, and automatically turns off the power supply to the power supply target during a predetermined time period, and automatically restarts the power supply after the time period. The feature is that it is turned on.

[0005]

[Means for Solving the Problems]

 A timer is provided for controlling energization OFF and energization ON for each of a plurality of energization ON and OFF switches on the switchboard, and a switching element controlled by the timer is provided in series with the switch.

[0006]

[Action]

 The switching element is controlled so that energization is turned off for a predetermined time period, and then turned on again by the timer.

【Example】

 Example 1. FIG. 1 is an external view of a switchboard according to the present invention. MS, S₁~ S₈Is the same as that shown in the conventional example. T₁~ T₈Is switch S₁~ S₈The time setting means provided in correspondence with the switch S and the timer S related circuit elements as shown in FIG.₁~ S₈Connected to each. Figure 2 shows an example of the connection between the timer and the switch. In the figure, MS is the main switch and S₁, S_Two, S _ThreeIs an ON / OFF switch that is commonly connected to the main switch and supplies power to each power supply target. For convenience of explanation, the switch S is shown here.₁ The connection between the timer and the timer will be explained as an example. Switch S_Two, S_ThreeNeedless to say, the same connection is made for ... 2 is switch S₁ Is a normally-closed contact connected in series with the contact, and this contact opens when the energization of the load 3 is turned off, and becomes the illustrated state when it is turned on. Reference numeral 4 denotes a battery that allows a timer, which will be described later, to function while the power supply is stopped, and is charged with electric power through a well-known charging circuit (not shown). Reference numeral 5 is an inverter that converts the output of the battery 4 into alternating current, and 6 is a timer, which is similar to a timer used for video, etc., and can be turned off and on by operating a pushbutton switch. Can be set to. A controller 7 receives the time signal 8 as a control signal output from the timer 6 and controls the exciting coil 9 of the normally closed contact 2. The time control by the timer 6 is performed as shown in FIG. That is, if the timer 6 is set to suspend from 12:00 to 13:00, energize from 13:00 to 20:00, deactivate from 20:00 to 08:00, energize from 08:00 to 12:00. Switch S at the set time₁ However, even if it is in the ON state, the normally closed contact 2 is opened to turn off the energization, and after a predetermined time, the normally closed contact 2 returns to the state shown in the figure and energization is restarted. In this way, the program for the set time is used to energize and de-energize the power supply target. If the user wants to energize urgently during the energization suspension time, it is necessary to reset the contents of the timer 6 to the zero-reset state and restore the contact 2. For that purpose, the switch 10 is operated to give the operation signal 11 as a reset signal to the timer 6 to initialize the contents of the timer 6.

Example 2. FIG. 4 shows another embodiment of the present invention, in which a normally closed contact 2 is commonly arranged between a main switch MS and switches S ₁ , S ₂ , S ₃ ... Which are commonly connected to the main switch MS, The contact 2 is opened and closed to energize and de-energize the entire switchboard. According to such a configuration, it is not necessary to provide a time setting means corresponding to each of the power supply ON and OFF switches, and the OFF and ON control can be performed by one time setting means. 5 (a), (b), (c), and (d) show display examples when the normally closed contact 2 is opened, and FIG. 5a is displayed when the contact 2 is opened in the configuration of FIG. The element 12 is adapted to emit light. FIG. 5b shows the case of the configuration of FIG. Further, FIG. 5c shows a case where the flicker signal generator 13 is connected to the AND gate 14. With this configuration, when the contact 2 is opened, the output of the AND gate 14 becomes the same as the flicker signal, so that the display element 12 blinks. To do. FIG. 5d shows the display body 15 in which the energized and de-energized characters are illuminated in mutually different colors by illuminating with the contact signal of the contact 2. When the contact 2 is closed, it is energized. Characters are illuminated and when contact 2 is open, non-energized characters are illuminated. If the display element and the display body are provided on the switchboard side of each switch, the visual recognition becomes easy.

[Effect of the device]

 Since the present invention has been described above, it has the effect of automatically stopping power supply during lunch breaks during periods of nonuse, such as at night, and preventing wasteful power consumption. Especially effective for forgetting to switch off the switchboard ititch. In the embodiment, the contact element is used as the switching element, but it goes without saying that the same applies to a contactless switching element. In addition, since the control circuit such as the timer is operated using the battery, control is possible even when the power is off.
