In the present invention, a solar power generation system is formed by a solar panel, a fire detection line, and a fire detection device.
FIG. 1 is a diagram for explaining an example of a fire detection line used in the present invention. 1 is a fire detection wire, 2 is a core wire, 3 is an inner conductor, 4 is a melt coating, 5 is an outer conductor, and 6 is a heat-resistant sheath. A set of conducting wires separated by the melt coating 4 is constituted by the inner conducting wire 3 and the outer conducting wire 5, and a fire of the solar panel is detected by monitoring a short circuit between the pair of conducting wires with a fire detection device (not shown). . As a method for detecting a short circuit, for example, there are a method for monitoring a voltage value, a method for monitoring a current value, and a method for monitoring a resistance value.

  The core wire 2 gives tensile strength to the fire detection wire 1. The inner conductor 3 is provided around the core 2 in a spiral manner. Thereby, since the inner side conductor 3 is arrange | positioned by the radius which is thick to some extent from the center of the detection line 1 for fires, it becomes easy to contact the outer side conductor 5 in the case of a fire. The melt coating 4 is provided so as to cover the outside of the inner conductor 3 in a cylindrical shape, and the outer conductor 5 is provided by spirally winding around the outer periphery of the melt coating 4. The melt coating 4 is formed of a soluble insulator and normally insulates the inner conductor 3 and the outer conductor 5 from each other. On the other hand, at the time of a fire, the melt coating 4 is melted by heat, and the outer conductor 5 comes into contact with the inner conductor 3 to cause an electrical short circuit. The winding direction of the outer conducting wire 5 is opposite to the winding direction of the inner conducting wire 3 and is easy to contact in the event of a fire. The heat-resistant sheath 6 is provided so as to cover the outside of the outer conductor 5 in a cylindrical shape. Since the inner conducting wire 3 and the outer conducting wire 5 are each formed by a plurality of conducting wires, it is difficult to disconnect, and there are many places where a short circuit occurs during a fire. Therefore, a fire can be reliably detected by the fire detection line 1. The formation by the plurality of conductors may be only one of the inner conductor 3 and the outer conductor 5, and the other may be one conductor. For detecting a fire, at least the inner conductor 3 and the outer conductor 5 are both one. A conducting wire is sufficient.

  If the core wire 2 is formed of a heat-resistant resin, the fire detection wire 1 is not easily disconnected in the event of a fire. The melt coating 4 may be an insulating material that melts by the heat of a fire, and an insulating material that melts at 100 to 200 ° C. is preferable. The heat-resistant sheath 6 is preferably made of a material that does not melt or burn below the temperature at which the melt coating 4 melts and detects a fire.

As the material of each member, for example, the core wire 2 is a flame retardant aramid fiber (para-aramid fiber, etc.), the inner conductor wire 3 and the outer conductor wire 5 are copper, the melt coating 4 is nylon 12, and the heat resistant sheath 6 is black poly Vinyl chloride can be used. By making the heat-resistant sheath 6 black, the far infrared rays are absorbed, and the fire detection line 1 can detect fire early. The heat-resistant sheath 6 is preferably a black color or dark color, but is not limited thereto, and may be any color with high heat absorption (brown, green, etc.).
The fire detection line 1 is not limited to the configuration shown in FIG. For example, a configuration may be adopted in which a soluble insulator is sandwiched between two piano wires and twisted.

  FIG. 2 shows a state in which a solar panel composed of a plurality of solar cell modules connected in series and parallel is installed on the roof. Fig.2 (a) is the figure which looked at the solar panel from the side in the installation state, and FIG.2 (b) is the figure which looked at the solar panel from the front side. Reference numeral 10 denotes a solar panel, 11 denotes a solar cell module, 12 denotes a mounting base, and 13 denotes a roof. The solar panel 10 is formed by the plurality of solar cell modules 11 and the mounting base 12. A mounting base 12 is provided on the roof 13, and a plurality of solar cell modules 11 are mounted thereon.

  As shown in FIG. 2A, the roof 13 is generally inclined. Since the solar panel 10 is installed along the tilted roof 13, the solar panel 10 is also tilted with the ridge side being high and the eaves side being low. Further, as shown in FIG. 2B, the solar cell modules 11 are arranged side by side in a plurality of directions in the inclination direction on a plane parallel to the roof 13. Generally, the mounting base 12 does not block between the solar cell module 11 and the roof 13, and there is a continuous space between the solar cell module 11 and the roof 13 from the eave side to the ridge side.

It is a figure. 111 denotes an upper sealing resin, 112 denotes a solar battery plate on which a plurality of solar cells are arranged, 113 denotes a lower sealing resin, and 114 denotes a back sheet. The solar cell plate 112 is enclosed between the upper sealing resin 111 and the lower sealing resin 113 on the back sheet 114 that supports the whole structure. Reference numeral 115 denotes a U-shaped module frame, which is provided on four surfaces around the solar cell plate 112 to form a durable solar cell module 11 that can withstand bending.

The upper surface side is referred to as the front side, and the lower surface side (rear side) is referred to as the back side.

  When a failure occurs in the solar panel 10, the solar cell plate 112 embedded in the solar cell module 11 partially generates heat. When the temperature of the heat generation exceeds a certain level, the upper sealing resin 111 and the lower sealing resin 113 ignite and the back sheet 114 burns. Combustion on the back side of the solar cell module 11 proceeds obliquely upward (ridge side) as indicated by an arrow in FIG. 3A, and further obliquely upward, beyond the lower side of the upper end portion 11a of the module frame 115, that is, 1 It is going to go to the upper solar cell module 11. Therefore, the combustion on the back side of the solar cell module 11 reaches the fire detection line 1 and is detected. The detection is performed by detecting that the inner conductor 3 and the outer conductor 5 are short-circuited due to melting of the melt coating 4 of the fire detection line 1 due to the fire of the solar panel 10.

The dotted line in FIG. 4B indicates that the fire detection line 1 is on the back side of the solar cell module 11. As described with reference to FIG. 2, there is generally a continuous space between the solar cell module 11 and the roof 13 from the eaves side to the building side, and the fire detection line 1 ensures that the fire spreads through this space. Can be detected. In addition, in the wiring position of the fire detection line 1 of Example 1 described in FIG. 4, even in the installation situation where the space between the solar cell module 11 and the roof 13 is blocked by the mounting base 12, flames and heat are fired. Since the detection line 1 is reached, the fire can be detected by the fire detection line 1.

FIG. 5A is a side view of the cross section in the building direction Y of FIG. 2B, and FIG. 5B is a cross section in the horizontal direction X orthogonal to the building direction Y viewed from the eave side. It is a figure. In FIG. 5A, the fire detection line 1 is wired to the lower end 11b on the back side of the upper (upper right) solar cell module 11, but the upper end 11a of the lower (lower left) solar cell module 11 is connected. Located in the vicinity. Therefore, it is possible to capture the heat of combustion from the eave side to the ridge side (obliquely upward) as indicated by the arrow with the fire detection line 1.

And the fire spread from the eaves side (slanting downward) of the solar panel 10 can be detected. For the solar cell module 11 on the most ridge side (uppermost level), a fire detection line 1 is further wired in a lateral direction at a position on the ridge side. The uppermost solar cell module 11 may be wired along the upper end 11a in addition to the lower end 11b.

Thereby, as shown to Fig.7 (a), the detection line 1 for fires is arrange | positioned in the position close | similar to the back seat | sheet 114, and high detection sensitivity can be obtained.

  FIG. 8 is a diagram illustrating a state in which the fire detection line 1 according to the third embodiment is installed on the solar panel 10 on the roof 13. 8A is a view of the solar panel 10 viewed from the side with the solar panel 10 installed on the roof 13, and FIG. 8B is a view of the solar panel 10 viewed from the front side. In order to wire the fire detection line 1 at the position of the third embodiment, holes are provided on both sides of the module frame 115, the fire detection line 1 is inserted, and the fire detection line 1 is wired sideways. Further, a fire detection line 1 having a length equivalent to the width of the solar cell module 11 is wired in advance between both side portions of the module frame 115, and is wired from the back side together with the generated power extraction wiring of the solar cell module 11. If it is taken out and connected to the adjacent solar cell module 11 or connected to a fire detection device (not shown), there is no need to insert the fire detection line 1 into the hole of the module frame 115.
