Earth leakage circuit-breaker refers to and a kind ofly not only main circuit can be switched on or switched off, and has the function to leakage current test and judgement, while there is electric leakage or insulation breakdown in main circuit, and the switch element that can main circuit be switched on or switched off according to judged result.And there is not any alarming device in traditional earth leakage circuit-breaker; when there is electric leakage in main circuit; although can disconnect main circuit; but not having any measure reminds people that circuit leaks electricity; now people are not knowing under the condition of circuit electric leakage; often also can again go opening power, electric accident easily occurs, this kind of phenomenon is very dangerous.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of protection switch with warning lamp electric leakage; can when electric leakage occurs main circuit, be disconnected in time, and have warning lamp to light after disconnecting main circuit; prompting people main circuit, in electric leakage state, needs on-call maintenance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of protection switch with warning lamp electric leakage is provided, for controlling switching on and off of main circuit, comprise: housing, the first fixed contact, the second fixed contact, guide rod, relay, tripping mechanism and warning lamp, described the first fixed contact and described the second fixed contact are installed in the inwall of described housing, the two ends of described guide rod are positioned at the centre of described the first fixed contact and described the second fixed contact, and be connected on described housing by described tripping mechanism, under described guide rod, be also fixedly connected with a T-shape magnetic patch, described magnetic patch every room directly over described relay, described warning lamp and described the second fixed contact are connected in series in both ends of power.
In preferred embodiment of the utility model, described power supply is provided with the battery case of lithium battery in being.
In preferred embodiment of the utility model, described guide rod is made by electric conducting material.
In preferred embodiment of the utility model, described warning lamp is arranged on the outer surface of described housing.
In preferred embodiment of the utility model, described tripping mechanism top is fixedly connected with insulated tension pole.
The beneficial effects of the utility model are: the utility model is provided with a warning lamp by the outer surface at earth leakage circuit-breaker housing; the second fixed contact is installed in inside; and warning lamp and the second fixed contact are connected on to both ends of power formation leakage warning system; when there is electric leakage; relay can be drawn to guide rod with the second fixed contact and contact connection circuit, thereby warning lamp is lighted, and can point out people's main circuit in electric leakage state; need on-call maintenance, prevent the generation of electric accident.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model in a preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, the first fixed contact, the 2, second fixed contact, 3, guide rod, 4, relay, 5, tripping mechanism, 6, warning lamp, 7, housing, 8, magnetic patch, 9, insulated tension pole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of protection switch with warning lamp electric leakage, for controlling being switched on or switched off of main circuit, comprise: housing 7, the first fixed contact 1, the second fixed contact 2, guide rod 3, relay 4, tripping mechanism 5 and warning lamp 6, described the first fixed contact 1 and described the second fixed contact 2 are all fixedly mounted on the inwall of described housing 7, the two ends of described guide rod 3 are positioned at the centre of described the first fixed contact 1 and described the second fixed contact 2, and be connected on described housing 7 by described tripping mechanism 5, under described guide rod 3, be also fixedly connected with a T-shape magnetic patch 8, described magnetic patch 8 every room directly over described relay 4, described warning lamp 6 and described the second fixed contact 2 are connected in series in both ends of power.
Further, described power supply is provided with the battery case of lithium battery in being, due to main circuit electric leakage, if continue to adopt the power supply in main circuit, more fragile warning lamp 6, therefore the battery case that is provided with lithium battery in adopting is as power supply, can be the in the situation that of energy savings opening warn lamp 6, can improve safety in utilization again.
Further, described guide rod 3 is made by electric conducting material, and when guide rod 3 switches between the first fixed contact 1 and the second fixed contact 2, circuit need to carry out conducting by guide rod 3, therefore needs to adopt the guide rod of electric conducting material.
Further, described warning lamp 6 is arranged on the outer surface of described housing 7, and the effect that makes to warn people is more obvious.
Further, described tripping mechanism 5 tops are fixedly connected with insulated tension pole 9, can guarantee the security performance that people operate, and can possess again and have easy to operate feature.
Be different from prior art, the utility model has disclosed a kind of earth leakage circuit-breaker with warning lamp, its groundwork principle is: by relay 4 and the first fixed contact 1 access main circuit, then pull-up is fixedly mounted on tripping mechanism 5 tops, and extend the insulated tension pole 9 outside housing 7, moving contact on guide rod 3 is contacted with the first fixed contact 1, conducting main circuit, now by warning lamp 6 in short-circuit condition, warning lamp 6 extinguishes, when there is electric leakage in main circuit, electric current on relay 4 increases, to being fixedly mounted on the magnetic patch 8 of guide rod 3 belows, produce huge suction, thereby drive guide rod 3 to depart from the first fixed contact 1, moving contact on guide rod 3 is contacted with the second fixed contact 2, conducting warning lamp 6, thereby the warning lamp 6 that is arranged on housing 7 outer surfaces lights, when it is found that warning lamp 6 lights, just can know that now main circuit is in electric leakage state, need carry out in time maintenance and inspection, prevent the generation of electric accident.
Be different from prior art; the utility model is provided with a warning lamp by the outer surface at earth leakage circuit-breaker housing; the second fixed contact is installed in inside; and warning lamp and the second fixed contact are connected on to both ends of power formation leakage warning system; when there is electric leakage, relay can be drawn to guide rod with the second fixed contact and contact connection circuit in time, thereby warning lamp is lighted; can point out people's main circuit in electric leakage state, need on-call maintenance.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
