Description

The present invention relates to a breaker breaking device that is plugged into an outlet driven by a seismic sensor.

In the event of a fire after an earthquake, there is an extremely high chance that a fire will occur due to a short circuit by supplying electric power restored to electrical devices and wiring destroyed by the earthquake. Conventionally, three countermeasures have been proposed as countermeasures for that purpose. FIG. 5 shows a drawing of an application representative of a conventional proposal of a seismic power shutoff device.

The first is to have a string on the knob and a weight connected to it to mechanically move the switch of the breaker switch. When the weight falls due to an earthquake, the string is pulled and the breaker is shut off. Is. It can be found in Patent Document 1. This is as shown at 5 − A in FIG. Similar applications can be found in JP 2000 − 113797, JP 11 − 219642, JP 2004 − 296421, JP 2006 − 164649, and Utility Model Registration No. 3019286.
Disadvantages are that it must be attached to each breaker, that it takes up space, and that it is immediately shut off by an earthquake, and it is not possible to take a time delay before the break.

The second one is equipped with a plug that plugs into a wall outlet, has an outlet into which a plug (load side) that connects to electrical equipment, etc., and a switch that shuts off the power supply between the plug and the outlet. It is designed to be cut off by a seismic means so that the power source is not connected to the load side. It can be found in Patent Document 2. This is as shown at 5 − B in FIG. Similar applications can be found in JP2004 − 304964, JP2008 − 172987, JP2013 − 156193, and JP2014 − 161213.
The disadvantage is that only the electrical equipment connected to this means can cut off the power, so if many outlets are cut off at the same time, a lot of means are required and the wiring between the outlet and breaker will be inconvenient. It cannot be dealt with.

The third is to provide a switch that connects one of the wires to the ground terminal via an electric resistance, and the switch is driven by an earthquake sensor to cut off the leakage breaker. It can be found in Patent Document 3. This is the one found in 5 − C in FIG. A similar application can be found in JP 2004 − 32876.
The advantage is that the earth leakage breaker exists at the largest source that aggregates all the breakers, and if this is cut off, the entire power supply of the building is cut off. It can be dealt with even if it happens. The disadvantage is that it is not possible to respond to partial breaks related to a certain breaker, and this is a response to this requirement. What is the first proposal to attach to each breaker knob? There was a need for something different, especially one that could shut off the associated breaker simply by plugging it into an outlet without changing the state of existing electrical equipment. Looking at the conventional proposal from this point of view, such a proposal cannot be found.

An outlet plug-in type seismic breaker breaking device according to the present invention comprises a plurality of plug terminals for plugging into an outlet and an electrical resistance for determining a current therebetween and a switch for connecting or blocking in series. It has a switch driver that connects and drives the switch for a predetermined time by a seismic signal received from an external seismic device, a power supply that supplies power to the switch, and a housing that houses them, and only when the switch is connected By flowing a predetermined current, the breaker is configured to be cut off by setting the current to be equal to or higher than the breaking current of the breaker connected to the outlet.
This will be described below with reference to the drawings.

FIG. 1 is a view showing an embodiment of the outlet plug-in type seismic breaker breaking device of the present invention.
In 1 − A,
A plurality of plug terminals 120 (two terminals in the figure) protrude from one surface of the housing 110. The plug terminal 120 is to be inserted into an outlet provided on a wall or the like.
A first switch 140 that is connected to or disconnected from the first electrical resistor 130 is connected in series between the plurality of plug terminals 120 on the inner side of the housing 110. The value of the first electric resistance 130 is set so that the breaker is cut off when a current flows through the connection of the first switch 140.

The connection of the first switch 140 is performed when an earthquake is detected. Therefore, a switch that obtains a seismic signal by the seismic receiver 150 for receiving a seismic signal from the seismic or external seismic device, and drives the first switch 140 for a predetermined time by the seismic signal. A driver 160 is provided.

An example of the predetermined time is the time required for the breaker to trip, and the time required to trip after a desired time delay, such as 3 minutes after obtaining the seismic signal. Can do. Also, if the power supply voltage between the outlet terminals is detected and the voltage is detected, the trip of the breaker is not completed, and the trip of the breaker is completed when the voltage is no longer detected. The first switch 140 can also be driven as the time required to trip.
For this reason, the switch driver 160 is advantageous because it has a function of setting a time delay and a trip time. If the breaker breaks off immediately and the lighting turns off, evacuation becomes dangerous, so it may be necessary to turn on the lighting during the evacuation. Because.

The switch driver 160 is thus driven to connect the first switch 140 for a predetermined time such as time delay or trip time. During this time, a current determined by the voltage of the first electrical resistor 130 and the power source flows between the plug terminals 120 connected to the outlet. Since this current is set larger than the breaking (trip) current value of the breaker connected to the outlet, the breaker is cut off. After a predetermined time, the first switch 140 is again in the disconnected state, but the breaker continues in the disconnected state until it is artificially turned on.
Needless to say, the switch driver 160 and the power source 170 that supplies power for driving to the seismic / receiver 150 that receives the seismic signal from the seismic or external seismic device are provided.

1 − B shows the housing 110 of 1 − A and the plug terminal 120 protruding from one surface. In this way, it can be inserted into an existing outlet.

In 1 − A, the power supply 170 is configured by a battery or the like, but in 1 − C, as another configuration of the power supply 170, terminals at both ends of the first switch 140 (example in the figure) or The wiring 171 drawn from between the plug terminals 120 is applied to the rectifier 172, smoothed by the capacitor 173, and charged to the rechargeable battery 174 (secondary battery). The rechargeable battery 174 always supplies power to the switch driver 160 and the seismic / receiver 150 that receives seismic signals from the seismic or external seismic device. When the wiring 171 is taken from the terminals at both ends of the first switch 140 as shown in the figure, the voltage applied to the rectifier 172 becomes zero when the first switch 140 is connected. In order to suppress the backflow, it is necessary to insert the diode 175 in the direction shown in the figure. When the wiring 171 is drawn from between the plug terminals 120, the voltage applied to the rectifier 172 is always a voltage supplied from the outlet and does not become zero, so the diode 175 is unnecessary.

Although the switch driver 160 can take various configurations, in this figure, the first switch 140 is an electromagnetic contact, an electromagnet coil 161 that drives the contact, and a second switch 162 connected in series to the coil 161. The second switch 162 may be driven by the controller 163 between the power supplies 170. In addition to the function of driving the second switch 162, the controller 163 receives the vibration signal from the seismoscope in some cases, and receives a vibration signal from the seismic sensor. You may provide the function to judge that there exists.

Further, if the first switch 140 has a semiconductor switch such as a thyristor, the first switch 140 and the switch driver 160 can be simply configured if the gate of the thyristor is driven by the output of the controller 163. it can. However, semiconductor switches are disadvantageous compared to normal contact switches because of their high internal resistance for these applications. Since various configurations are possible in this way, the example is not limited to the illustration.

The first electric resistor 130 is attached to one side of the first switch 140, but can be divided into both sides. FIG. 4 describes such a situation. The first electrical resistance 130 is divided into two electrical resistances, the first electrical resistances 130A and 130B.

FIG. 2 is a diagram showing an embodiment of a usage state of the outlet plug-in type seismic breaker breaking device of the present invention.
2 − A shows an existing outlet stack 210 on a wall or the like, and a plurality of outlets 210A, 210B,... Are collected (of course, may be independent) and connected to the breaker 220A.
Including the breaker directly connected to other outlet stacks and devices, the earth leakage breaker 230 is connected and connected to an outdoor power source. The earth leakage breaker 230 shuts off the power if there is an earth leakage no matter where the earth leakage occurs. 2 − B shows a normal plug 240, for example, plugged into an outlet 210A. 2 − C shows the plug-in type seismic breaker breaking device 100 of 1 − A in FIG. 1, but it may be of 1 − B. The form was like 1 − B in FIG. For example, the plug terminal 120 is inserted into the outlet 210D.

2 − D shows a state where the outlet plug-in type seismic breaker breaking device 100 is inserted into the outlet 210D. In this state, when there is an earthquake and there is a seismic signal, the first switch 140 is connected for a predetermined time, and the current determined by the first electrical resistance 130 and the voltage flows to the outlet 210D, and the breaker 220A This trips until it trips and becomes a disconnected state, and it is continued until it is manually connected again. Breakers 220B and 220C into which the plug-in type seismic breaker breaking device 100 is not inserted are not cut off.

FIG. 3 is a view showing another embodiment of the outlet plug-in type seismic breaker breaking device of the present invention.
The first switch 130 is pulled out from the middle of the first electric resistor 130, and the third switch 301 is connected to the third resistor 301. The third switch 301 is pulled out of the casing 110 and connected to another ground terminal. The third switch 301 receives the seismic signal and is driven and connected by the switch driver 160. When connected, it means that there has been a leakage, so that the leakage breaker 230 is cut off in addition to the breaker. Although not shown in the figure, if a second electrical resistance is loaded in series with the third switch, the setting of the leakage current is facilitated.

There are many examples of devices that can be used as a seismic device. However, seeing examples in the patent literature, JP 2013 − 24769, JP 2009 − 156733, JP 2008 − 145115, Japanese Patent Laid-Open No. 2006 − 105632, Japanese Patent Laid-Open No. 2002 − 243531, Japanese Patent Laid-Open No.2001 − 108516, Japanese Patent Laid-Open No.11 − 190657, and the like. Also, as a small and easy-to-use commercial product, Ikukata Manufacturing Co., Ltd. manufactures and sells it, so it can be used as a part. In addition, it is possible to use means for measuring the vibration with a pressure sensor and analyzing the frequency of the vibration to detect earthquake motion.

As described above, the outlet plug-in type seismic breaker breaking device according to the present invention is simply plugged into the outlet, and when there is an earthquake of a predetermined scale, the breaker related to the outlet is immediately or after a desired time delay. Since it is cut off, it is very convenient for industrial use.
