Concrete, described hot melt sheet can adopt fusing point to be made lower than the metal material of 70 ℃.
Photovoltaic combiner box flameproof protection device of the present utility model; it is applied to header box flameproof protection device with low-melting-point metal; the characteristic of utilizing low-melting-point metal to meet the heat thawing starts the trigger equipment that is comprised of parts such as spring and thimbles; thereby reach the function of excess temperature fire prevention automatic trip outage, for photovoltaic plant provides safety guarantee.
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 flameproof protection 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 flameproof protection device, it comprises: the base plate 10 of offering a through hole, the sleeve 20 of one end opening, and one end be inserted in contact 30 in sleeve, the through hole of described sleeve 20 openends and base plate 10 is oppositely arranged, be installed with the first spring 12 between this base plate 10 and sleeve 20, be provided with successively hot melt sheet 22 in sleeve 20, against the pad 24 that is arranged at hot melt sheet 22 1 sides and the second spring 26, described contact 30 1 ends pass the first spring 12 successively, hot melt sheet 22, be located at sleeve inner after pad 24 and the second spring 26, contact 30 other ends stretch out in sleeve 20 and are oppositely arranged with the through hole of base plate 10.Photovoltaic combiner box flameproof protection installation composition of the present utility model one temperature-sensitive machinery triggering system; it is arranged on the interior disconnect of header box; upwards compress by pad 24 the second spring 26 that is placed in sleeve 20, and make the second spring 26 be in compressive state by hot melt sheet 22.At ordinary times, contact 30 is remained on the fixed position by the first spring, if on fire or temperature anomaly rising in the header box casing, hot melt sheet 22 melts, and the second spring 26 releases energy, and contact 30 is ejected downwards, its strength is enough to press the short circuit trigger point of disconnect, thereby the cut-out electric current, after failure of current, the pyrotoxin of header box disappears, therefore can not catch fire.
Wherein, described base plate 10 is provided with a shell 14, and sleeve 20 fixedly is suspended at base plate 10 upsides by this shell 14.
