Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model photovoltaic combiner box telemechanical protective device.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of photovoltaic combiner box telemechanical protective device, it comprises: base plate 10, the sleeve 20 that is suspended at base plate 10 tops, the cam 30 that can move up and down with moving sleeve 20, the reducing motor 40 of controlling with cam 30 interlocks, and with the far-end remote control device (not shown) of reducing motor 40 communication connections; Offer a through hole on described base plate 10, be installed with a spring 12 between base plate 10 and sleeve 20, sleeve 20 lower ends and this lead to the hole site corresponding section are provided with a contact 22, and described spring 12 is sheathed on contact 22 outsides.The utility model can be applied in conventional header box, when the header box overtemperature alarm or when needing manual intervention to open circuit, can be by this device of far-end remote control device remote activation, thereby can reach the function of telemechanical tripping operation outage, solve existing photovoltaic combiner box and burn and the problem such as fire safety evaluating hidden danger because excess temperature, the reason such as open circuit cause in long-term use procedure, facilitate opening circuit of remote control switch.
Wherein, described base plate 10 is provided with a shell 14, and sleeve 20 can fixedly be suspended at base plate 10 upsides by this shell 14.
As a kind of specific embodiment of the present utility model, described sleeve 20 places, centre positions are provided with an outstanding boss structure 24, and cam 30 is against the upside that is arranged at this boss structure 24.In the utility model, described reducing motor 40 and far-end remote control device communication connection, this far-end remote control device can be arranged in the master control platform of power station.On fire or temperature anomaly rising in the header box casing, power station master control platform has the audible and visual alarm prompting, administrative staff can send break signal by the far-end remote control device, thereby start reducing motor 40, reducing motor 40 band moving cams 30 move down, cam 30 acts on the boss structure 24 of sleeve 20, thereby impel sleeve 20 band moving contacts 22, contact 22 is ejected downwards, its strength is enough to press the trigger point of opening circuit of air switch of opening circuit, cut off electric current, after failure of current, the pyrotoxin of header box disappears, therefore can not catch fire.
