Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric breaker, and more particularly to a seismic breaker for an apparatus for preventing a disaster caused by a fire caused by electricity during an earthquake.

[0002]

2. Description of the Related Art A general breaker operates only with a current flowing above a certain level and merely stops the flow of electricity. As a result, it was not possible to respond to the disaster caused by the earthquake, and it was not possible to stop the damage in advance.

[0003]

The conventional circuit breaker cannot cope with the vibration caused by the earthquake by merely stopping the flow of electricity at a certain level or more, and has a problem in preventing a fire accident caused by electricity.

An object of the present invention is to cut off input electric power from a breaker at a constant seismic intensity, and to minimize the possibility of a fire caused by electric power during an earthquake. It monitors the deterioration of parts and the state of the flow of electricity for 24 hours, thereby providing an earthquake breaker that can respond to an earthquake.

[0005]

In order to achieve the above object, an earthquake breaker according to the present invention is provided in a rectangular outer box.
Function.

By automatically attaching the plunger shown in FIG. 2 to cut off the power supply, and attaching the plunger horizontally instead of at the center so as not to interfere with the breaker, wiring work is easy and automation can be easily performed. .

The main parts such as the plunger in FIG. 2, the vibration sensor in FIG. 3, and the heater function are integrally mounted on the microcomputer board, and when a failure occurs or the parts are replaced, only those parts should be replaced. Can be cheaper for the user and the work can be done quickly and easily.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The outer case shown in FIG. 1 is made of plastic and is formed by extrusion molding. Entering there, the device of the cutting breaker is arranged. 2 is made of brass and fixed. 3 is made of copper and contacts with the contact of 2 at the time of power input, and 3 at the time of cut.
Lifts. Usually, the input is done manually by 5,
The power cut is automatically performed by the plunger 4 when the vibration sensor 8 detects a constant seismic intensity during an earthquake, but electricity does not flow to the four plungers unless the vibration sensor receives a constant seismic intensity. The deterioration rate of parts is very low, and the input power is maintained as a whole by passing a part to the microcomputer, and then flows to each breaker as usual.

The microcomputer board has a DC stabilizer for plunger output and a heater for protecting electric components from cold.
The microcomputer manages the whole. The vibration sensor is a sensor for outputting the plunger, and the input power supply AC is converted into DC by the DC stabilizer and flows to the plunger via the vibration sensor.

The microcomputer monitors the deterioration state of the components of the earthquake breaker for 24 hours, the state of the flow of electricity, and the like. When the components are deteriorated or the breaker is cut off, the microcomputer blinks by the LED and outputs a buzzer. , Can be notified by a voice guide function.

[0011] Even if no damage is caused by changing the microcomputer, if it is desired to cut off the power supply for safety, remote control can be easily performed by telephone.

By providing a heater function so that it can be used irrespective of the season in Japan, it is possible to use the apparatus safely in a cold area by protecting the electric parts from deterioration.

The use of a high voltage is possible by making the contact part of (2) and (3) three-phase, so that it has become an earthquake breaker that can be used for a wide range of disaster countermeasures.

[0014]

According to the present invention, by combining a sensor that can cope with an earthquake that did not exist in the past, an effect of preventing a fire due to electricity that is likely to be caused by an earthquake is obtained, so that it is possible to take quicker measures against a disaster. Was.

By arranging a plunger, a vibration sensor, and a microcomputer for managing the whole in the breaker, the breaker can cope with an earthquake which was impossible until now, so that it can be more effectively prevented in the event of a disaster. I can do it quickly.

Moreover, since it is small and lightweight, it is easy to install and does not get in the way, and it is an easy-to-use earthquake breaker with a buzzer, LED blinking, and voice guide functions.

The use of a high voltage is possible by making the contact portion of (2 · 3) three-phase, so that a wide range of disaster countermeasures has become possible.

This is a seismic breaker that can be easily remote-controlled by telephone if it is desired to cut off the power for safety even if no damage is caused by changing the microcomputer.
