Summary of the invention
The utility model is for the technological deficiency of prior art; a kind of earth leakage protective device is provided; this earth leakage protective device has temperature sense probe, Smoke Detector and warning device simultaneously, thus makes earth leakage protective device effectively can play its power-off work when fire occurs in order to avoid circuit in fire to damage the larger danger brought.
For realizing above technique effect, the utility model by the following technical solutions:
A kind of earth leakage protective device; comprise circuit box, pedestal, switch, enclosing cover; also comprise temperature sense probe, Smoke Detector, alarming horn simultaneously; wherein pedestal is positioned on an outer surface of circuit box; switch is positioned on pedestal; temperature sense probe is positioned on above-mentioned outer surface, and enclosing cover to cover on above-mentioned outer surface and by pedestal, switch and temperature sense probe cover wherein, and Smoke Detector and alarming horn to be positioned on this earth leakage protective device and to be in beyond scope that above-mentioned enclosing cover covers.
On the basis of above technical scheme, can carry out preferably following:
Preferably, also comprise wireless warning signal generator, described wireless warning signal generator to be positioned on earth leakage protective device and to be in beyond scope that above-mentioned enclosing cover covers.
Preferably, described outer cover to exist make its inside and outside passage carrying out air exchange.
The passage of above-mentioned air exchange can be preferably enclosing cover and not exclusively cover above-mentioned outer surface and the space left; Or be preferably the outer hollow out covering existence.
Described hollow out can be preferably circular hole or strip slit.
In above technical scheme, temperature sense probe and Smoke Detector are respectively used to detect the high ambient temperature because fire causes and flue gas, can regard as simultaneously when the two detects fire characteristic time and there occurs fire and then cut off circuit, still be communicated with caused secondary injury to avoid circuit in fire.When the automatic shutdown circuit or while cutting off circuit because of the traditional reason such as electric leakage, circuit overload, alarming horn sends stronger alarm sound, carries out rapidly speedily carrying out rescue work, avoiding the abnormality duration long to point out staff because detecting fire information.When this earth leakage protective device has wireless warning signal generator, when above-mentioned situation arrives not only automatically to start alarming horn, wireless warning signal generator sends alarm signal simultaneously, cannot be heard to avoid alarm sound the danger that causes.
In above technical scheme, arranging enclosing cover is consider aesthetic considerations, and enclosing cover leave make its inside and outside passage carrying out air exchange be in order to ensure temperature sense probe more can objectively respond ambient temperature.The utility model structure is simple, be skillfully constructed and cost is lower, has outstanding scale application prospect.
