Field of the Invention The present invention relates to a vibration detection circuit breaker, and more particularly to a vibration detection circuit breaker for detecting electrical vibration and opening contacts of the circuit breaker to protect electrical equipment when a large vibration such as an earthquake occurs. About the vessel.

When the main contact is in the closed state, a ground fault current flowing through the main contact is detected, and the main contact is opened by releasing the latch mechanism of the main contact to cut off the current. Thus, when an electric leakage, that is, a ground fault current occurs, the supply of electric power can be promptly stopped to protect a person or the like.

This overcurrent circuit breaker protects the electric equipment by, for example, opening a main contact of the circuit breaker and cutting off the supply of electric power when a current of a predetermined value or more flows through the electric equipment connected to the terminal. .

発生の原因ともなる。When the surrounding environment changes, for example, when a building is damaged due to the occurrence of a large earthquake or the like, there is a case where it is necessary to immediately cut off the power supply. However, in the case where no overcurrent or ground fault current occurs despite the damage of a house or the like, power is continuously supplied. In such a case,
For example, high-temperature heating is continued despite the fact that a heat insulating part such as a heating furnace is damaged, which may cause a fire during an earthquake.

合も少なくない。[0005] Normally, when a large earthquake or the like occurs, the power supply source can temporarily stop the power transmission and restart the power transmission when the power transmission and distribution equipment is confirmed to be temporarily safe. However, it is difficult to confirm safety up to the terminal electrical equipment. In such a case, it is preferable to restart the power supply after confirming the safety of the electrical equipment managed by the user of the terminal equipment, but the electrical equipment manager should check the equipment in an emergency evacuation or the like. There are many cases where it is not possible.

Thus, for example, it is possible to prevent the occurrence of a fire or the like due to the continuation of power supply in the event of a large earthquake, and complete protection of electrical equipment. Further, since the vibration detection mechanism has a threshold value, the circuit cutoff mechanism does not operate for small vibrations, and can perform a protection operation only for vibrations exceeding a dangerous predetermined value.

The vibration detection element 11 is a detection element that detects a large vibration such as an earthquake. The electric signal output from the vibration detecting element 11 is amplified by the amplifier circuit 12,
The contact release device 13 is driven. Contact removal device 1
When 3 is driven, the main contact 14 that supplies power from the power supply side power supply line 15 to the electric facility side power supply line 16 performs an opening operation, and cuts off the supply of power.

ンサでも勿論よい。As the vibration detecting element 11, for example, a moving coil type speed sensor utilizing a dynamic electromagnetic phenomenon is used. The moving coil vibration sensor converts the vibration into a voltage signal using Faraday's law of electromagnetic induction. In addition to the moving coil type vibration sensor, other types of vibration sensors may be used as long as they can output an electric signal with respect to a large vibration such as an earthquake.

生じるものでも勿論よい。In this embodiment, the amplifier circuit 12 supplies a drive current to the contact release device 13 only when a signal having a magnitude equal to or larger than a certain threshold value is input. As a result, the contact release device does not operate with a small amplitude vibration, and opens the main contact when a large vibration of a predetermined value or more is applied, and cuts off the current. It is needless to say that the vibration detecting element 11 itself has a threshold characteristic and generates an electrical output when detecting a vibration of a predetermined value or more.

The earth leakage breaker 20. The earth leakage breaker 20 further includes a vibration detection mechanism 21 that includes a vibration detection element that outputs an electric signal by detecting vibration, and an amplifier that amplifies the output of the element.

And the latch mechanism of the contact release device 13 is released, and the main contact 14 is opened, as in the case of detecting the ground fault current. Thus, the supply of power from the power supply line 15 on the power supply side to the power supply line 16 on the electric equipment side is cut off. Therefore, according to the earth leakage breaker of the present embodiment,
The circuit can be interrupted by detecting the leakage, and the circuit can also be interrupted by detecting the vibration.

An overcurrent cut-off mechanism 26 that cuts off power supply from the power supply side power supply line 15 to the electric facility side power supply line 16 is provided. The overcurrent breaker 25 is also provided with the vibration detecting mechanism 2 described above.
1 is provided. As a result, the overcurrent cutoff device can cut off the circuit when a normal overcurrent occurs, and also performs an operation of opening the main contact 14 against a large amplitude vibration such as an earthquake.

等を未然に防ぐことができる。When the main contact 14 is interrupted by the vibration detection circuit breaker, the earth leakage circuit breaker, and the overcurrent circuit breaker, the interruption state continues once it is interrupted, similarly to the conventional earth leakage circuit breaker and the like. For this reason, after confirming that there is no failure of the electric equipment due to the vibration that causes the operation of the vibration detecting element 11 is applied, the electric equipment does not return unless the electric equipment manager performs a return operation again. . Therefore, at the time of a disaster such as an earthquake, the vibration is detected and the circuit is automatically brought into a continuous cutoff state, so that a fire accident or the like caused by a malfunction of the electric equipment can be prevented.
