參閱圖2，本發明用於太陽能電力傳送的防災斷路系統之一實施例，用於電連接於一太陽能板模組9，該太陽能板模組9用於將太陽能轉換成一轉換電訊號。於本實施例中，該太陽能板模組9是由多個太陽能板（圖未示）串接而成，該轉換電訊號為直流電型式且為該等太陽能板的共同串聯電壓。Referring to FIG. 2, an embodiment of the disaster prevention circuit breaker system for solar power transmission of the present invention is used for electrical connection to a solar panel module 9 for converting solar energy into a converted electrical signal. In this embodiment, the solar panel module 9 is formed by connecting a plurality of solar panels (not shown) in series, and the converted electrical signal is a direct current type and is a common series voltage of the solar panels.

該用於太陽能電力傳送的防災斷路系統包含一開關單元2、一電氣轉換單元3，及一控制單元4。The disaster prevention circuit breaker system for solar power transmission includes a switch unit 2, an electrical conversion unit 3, and a control unit 4.

該開關單元2包括一電連接該太陽能板模組9以接收該轉換電訊號的一輸入端子21、一用於輸出該轉換電訊號的一輸出端子22，及一電連接該輸入端子21及該輸出端子22之間並可受一供應電源供電控制而於一第一導通狀態及一第一斷路狀態之間變換的切換模組23。於本實施例中，該切換模組23為絕緣柵雙極電晶體（Insulated Gate Bipolar Transistor，IGBT），在其它的實施態樣中，也可以是矽控整流器（Silicon Controlled Rectifier，SCR ）、繼電器（Relay）、電磁開關或其它可做為開關功能的電子零件。於本實施例中，該供應電源為交流電源，但在其它的實施態樣中，該供應電源也可以是直流電源。The switch unit 2 includes an input terminal 21 electrically connected to the solar panel module 9 to receive the converted electrical signal, an output terminal 22 for outputting the converted electrical signal, and an electrical connection between the input terminal 21 and the The switching module 23 between the output terminals 22 can be controlled by a power supply to switch between a first on state and a first off state. In this embodiment, the switching module 23 is an insulated gate bipolar transistor (IGBT). In other implementations, it may also be a silicon controlled rectifier (SCR), a relay (Relay), electromagnetic switch or other electronic parts that can be used as a switch function. In this embodiment, the power supply is an AC power supply, but in other implementation aspects, the power supply can also be a DC power supply.

該供應電源正常供電時，該切換模組23通電而處於導通的該第一導通狀態，使該輸出端子22透過該切換模組23而與該輸入端子21相互導通以輸出該轉換電訊號，該供應電源不供電時，該切換模組23未通電而處於斷開的該第一斷路狀態，使該輸出端子22與該輸入端子21不導通而無法輸出該轉換電訊號。When the power supply is normally powered, the switching module 23 is energized and is in the first conduction state, so that the output terminal 22 is connected to the input terminal 21 through the switching module 23 to output the conversion electrical signal. When the power supply is not powered, the switching module 23 is not energized and is in the first disconnected state, so that the output terminal 22 and the input terminal 21 are non-conducted, and the converted electrical signal cannot be output.

該電氣轉換單元3電連接該輸出端子22並將該轉換電訊號轉換成供市電使用的交流電型式的該供應電源。The electrical conversion unit 3 is electrically connected to the output terminal 22 and converts the converted electrical signal into the AC power supply source for commercial power.

要說明的是，該電氣轉換單元3是用來將直流電型式的該轉換電訊號進行電壓調整後，再轉換成交流電型式的該供應電源，由於此為一般的太陽能技術手段，因此本說明書不再進一步對此進行說明。It should be noted that the electrical conversion unit 3 is used to adjust the voltage of the converted electrical signal of the direct current type, and then convert it into the power supply of the alternating current type. Since this is a general solar technology method, this description will not be omitted. This will be further explained.

該控制單元4電連接於該切換模組23及該電氣轉換單元3之間並用於將該電氣轉換單元3輸出的該供應電源傳送至該切換模組23，該控制單元4可受控制而於一第二導通狀態及一第二斷路狀態之間變換，於該第二導通狀態時，該控制單元4導通而將該電氣轉換單元3輸出的該供應電源傳送至該切換模組23，於該第二斷路狀態時，該控制單元4斷開而無法將該供應電源傳送至該切換模組23。要說明的的是，該控制單元4可透過手動開關切換、遙控切換或網路遠端控制切換的方式達成。The control unit 4 is electrically connected between the switching module 23 and the electrical conversion unit 3 and is used to transmit the power supply output from the electrical conversion unit 3 to the switching module 23. The control unit 4 can be controlled to Change between a second on state and a second off state. In the second on state, the control unit 4 is turned on to transmit the supply power output from the electrical conversion unit 3 to the switching module 23, where In the second disconnection state, the control unit 4 is disconnected and the power supply cannot be transmitted to the switching module 23. It should be noted that the control unit 4 can be achieved through manual switching, remote control switching, or remote network control switching.

使用時，當該控制單元4被控制於該第二導通狀態，市電所提供的該供應電源會通過該控制單元4而對該切換模組23供電，以使該切換模組23切換至該第一導通狀態，此時，太陽能板模組9在將所接收的太陽能轉換成該轉換電訊號後，該轉換電訊號就會通過該輸入端子21、該切換模組23及該輸出端子22而輸出至該電氣轉換單元3，而經由該電氣轉換單元3轉換後的該供應電源就會匯流至市電中而達到提供太陽能電力的效果。When in use, when the control unit 4 is controlled in the second conduction state, the supply power provided by the mains will supply power to the switching module 23 through the control unit 4, so that the switching module 23 is switched to the first In a conducting state, at this time, after the solar panel module 9 converts the received solar energy into the converted electrical signal, the converted electrical signal will be output through the input terminal 21, the switch module 23, and the output terminal 22 To the electrical conversion unit 3, the supply power converted by the electrical conversion unit 3 will be converged to the city power to achieve the effect of providing solar power.

當該電氣轉換單元3因為線路老舊破皮而短路產生火花，進而使該電氣轉換單元3故障而不再轉換該供應電源時，由於電氣迴路中斷，因此該太陽能板模組9就無法繼續將太陽能轉換成該轉換電訊號，而避免繼續供電所可能產生的危險。When the electrical conversion unit 3 is short-circuited due to the old and broken wire and sparks are generated, and the electrical conversion unit 3 fails and no longer switches the power supply, the solar panel module 9 cannot continue to connect due to the interruption of the electrical circuit. The solar energy is converted into the converted electrical signal, so as to avoid the danger that may be caused by the continued power supply.

而當發生災害而使市電斷電時，由於該切換模組23不再受到該供應電源供電，該切換模組23即會切換至該第一斷路狀態，而使電氣迴路中斷，因此該太陽能板模組9無法繼續將太陽能轉換成該轉換電訊號，而避免災害發生時繼續供電所可能產生的危險。When a disaster occurs and the mains power is cut off, since the switching module 23 is no longer powered by the power supply, the switching module 23 will switch to the first disconnected state, and the electrical circuit is interrupted, so the solar panel The module 9 cannot continue to convert solar energy into the converted electrical signal, so as to avoid the possible danger of continuing to supply power when a disaster occurs.

另外，當需要進行維修作業時，透過控制使該控制單元4切換至該第二斷路狀態後，即會使該切換模組23不再受到該供應電源供電，此時該切換模組23即會切換至該第一斷路狀態，使電氣迴路中斷，因此該太陽能板模組9無法繼續將太陽能轉換成該轉換電訊號，就可方便進行維修。In addition, when maintenance operations are required, after the control unit 4 is switched to the second disconnected state through control, the switching module 23 will no longer receive power from the power supply. At this time, the switching module 23 will Switching to the first disconnection state interrupts the electrical circuit. Therefore, the solar panel module 9 cannot continue to convert the solar energy into the converted electrical signal, and it is convenient for maintenance.

要說明的是，由於電氣迴路的陽極或陰極的其中一線路形成斷路時，整個電氣迴路就會中斷，因此該開關單元2及該控制單元4只要連接於電路迴路中的至少其中一線路間就能達成保護的效果。It should be noted that when one of the anode or cathode lines of the electrical circuit is disconnected, the entire electrical circuit will be interrupted. Therefore, the switch unit 2 and the control unit 4 only need to be connected between at least one of the circuits in the circuit circuit. Can achieve the effect of protection.

另外，於本實施例中，該控制單元4是電連接於該切換模組23及該電氣轉換單元3之間，且該供應電源為市電所使用的電源，但在其它的實施態樣中，該控制單元4也可以是連接於該切換模組23及一外部電源（圖未示）之間，此時該供應電源為該外部電源所使用的電源，而同樣能受到控制而達到切換的效果。In addition, in this embodiment, the control unit 4 is electrically connected between the switching module 23 and the electrical conversion unit 3, and the supply power is the power used by the commercial power supply, but in other implementations, The control unit 4 can also be connected between the switching module 23 and an external power supply (not shown). At this time, the power supply is the power used by the external power supply, and it can also be controlled to achieve the switching effect. .

綜上所述，藉由設置受該供應電源供電控制的該切換模組23，使該切換模組23能在該供應電源不供電時切換至該第一斷路狀態，進而使該太陽能板模組9無法繼續將太陽能轉換成該轉換電訊號，以避免災害發生時繼續供電所可能產生的危險，故確實能達成本發明之目的。In summary, by arranging the switching module 23 controlled by the power supply, the switching module 23 can switch to the first disconnected state when the power supply is not powered, so that the solar panel module 9 It is impossible to continue to convert solar energy into the converted electrical signal to avoid the possible dangers of continuing to supply power when a disaster occurs, so it can indeed achieve the purpose of the invention.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention.
