Document Type and Number:
Japanese Patent JP6990394
Kind Code:
B2
Abstract:
To provide a vibration-sensitive breaker control device capable of accurately detecting an earthquake intensity and appropriately breaking an electric leak breaker in accordance with the earthquake intensity correspondingly to a shape of a plug socket tap of a building or an ambient environment.SOLUTION: A breaker control device 1 comprises a case 2, a pair of insertion plugs 3 protruding from the case 2, and a ground pin 5. An acceleration sensor 6 and a control part 7 are built in the case 2. The control part 7 includes a discrimination part 8 for discriminating an earthquake intensity, a warning part 9 and the like. An angle correction part 23 which adjusts an attitude of the case 2 when the breaker control device 1 is attached to a plug socket tap 30, is provided on an opposite face 2a of the case 2. The angle correction part 23 is a screw member which has a male screw part 23a formed on a front face, screwed to a female screw part 24 which is provided in the case 2, and formed so as to freely move forward to and backward from the opposite face 2a.SELECTED DRAWING: Figure 2
