The beneficial effects of the utility model are: be convenient to realize fast detecting and switching, and easy to use, easy and simple to handle, save time, operating efficiency is high.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure: 1-casing; 2-observation window; 3-gauge table; The main overload protective device of 4-; 5-overload protective device for subsequent use; 6-radiator fan; 7-temperature detection sensor; 8-alarm module; KM1-relay.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, this embodiment by the following technical solutions: it comprises casing 1, observation window 2, gauge table 3, main overload protective device 4, overload protective device for subsequent use 5, radiator fan 6, temperature detection sensor 7, alarm module 8, relay K M1, casing 1 is provided with observation window 2, gauge table 3, main overload protective device 4, overload protective device 5 for subsequent use, radiator fan 6, temperature detection sensor 7, alarm module 8, relay K M1 is installed in the inside of casing 1, temperature detection sensor 7 is connected with the controller of radiator fan 6, the output line of gauge table 3 respectively with one end of main overload protective device 4, one end of relay K M1 first couple of normally-closed contact KM1-1 connects, the other end of main overload protective device 4 is connected with one end of relay K M1 coil, the other end of relay K M1 coil is connected with one end of alarm module 8, one end of the other end and relay K M1 second couple of normally-closed contact KM1-2 of alarm module 8 is connected, the other end of relay K M1 second couple of normally-closed contact KM1-2 is connected with one end of overload protective device 5 for subsequent use, the other end of the other end and relay K M1 first couple of normally-closed contact KM1-1 of overload protective device 5 for subsequent use is connected.
Further, described alarm module 8 is audible-visual annunciator.
Further, described radiator fan 6 is turbine type radiator fan.
The operation principle of this embodiment is: realize overload protection by main overload protective device 4; when there is overload or short circuit in main overload protective device 4; main overload protective device 4 meeting power-off; relay K M1 coil losing electricity; relay K M1 first pair of normally-closed contact and second pair of normally-closed contact close; overload protective device 5 for subsequent use works; the protection of realizing circuit; its fail safe, switches fast, saves time; when overload protective device 5 for subsequent use works; alarm module 8 realizes reporting to the police, and adopts radiator fan 6 to realize heat radiation, increases the service life.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
