Seismoscope and earthquake-proof earth leakage breaker for earth leakage breaker

摘要

(57) Abstract (Modified) Topic At the time of earthquake disaster, the electrical machinery and apparatus and the house inside the house which collapsesIt is due to the damage of the inside wiring, it makes the fire break-out prevention measure from short circuit,To assure the miniaturization of the te and the seismoscope, unite to the earth leakage breaker, electric leakageWith interlocking to the test circuit, economic earthquake-proof electric leakageTo offer the stopping/deciding vessel, widely generally, the electrical machinery and apparatus and the interior at the time of earthquake disasterFire from damage of wiring is prevented. Solutions As for seismoscope for earth leakage breaker, spherical metal container 9Inside, insulating with the container, the electrode 5 which it provides and spherical metal permitting/insertingThe electrode it encloses inside 2 which is connected to vessel 9 and spherical metal container 9The seismoscope which designates the mercury switch by the mercury bulb 10 which it does as merit11, the earthquake sensing output terminal base was provided, safe braker agreement formaYou enclosed to the resin insulating stowage box, the seismoscope for the earth leakage breaker. Electric leakageLead line for external test switch of breaker, earth leakage breakerWith jointing to the earthquake sensing output terminal base of the business seismoscope, the seismoscopeWith the signal by the mercury switch, cutoff of the earth leakage breaker columnu. Earthquake-proof of one forma which can give earthquake sensitive interception function in the earth leakage breakerEarth leakage breaker.
