Description

태양광 발전 접속반Photovoltaic connection board
본 발명은 태양광 발전 접속반에 관한 것으로, 더욱 상세하게는 방열특성을 획기적으로 개선하고, IoT 통신 모듈을 포함하여 태양광 패널을 모니터링하는 기능을 제공하는 태양광 발전 접속반에 관한 기술이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photovoltaic power generation connection module, and more particularly, to a photovoltaic generation connection module that improves heat dissipation characteristics drastically and provides a function of monitoring a photovoltaic panel including an IoT communication module.
접속반은 태양광패널과 인버터 사이에서 직류전력을 모아 인버터에 전달해주는 역할을 한다. 태양광 발전시 발생하는 전력은 직류로, 태양광패널에서는 직류전력이 발생되고 발생된 직류전력을 교류전력으로 변환해주는 것이 인버터이다. 태양광 발전소 100kW 기준 약 364개 정도의 태양광패널을 설치하게 되는데, 태양광패널에서 생산된 전력을 한군데로 모아 인버터에 전달해주는 역할을 해주는 것이 태양광 발전 접속반이다.The connection panel collects the DC power between the solar panel and the inverter and transfers it to the inverter. The power generated in the solar power generation is DC, the DC power is generated in the solar panel, and the inverter converts the generated DC power into AC power. About 364 photovoltaic panels based on 100kW of solar power plant are installed. It is the photovoltaic connection panel that collects the power produced by the photovoltaic panels and transfers them to the inverter.
접속반은 태양광패널에서 생산된 직류전류를 직접적으로 인버터에 연결하면 인버터에 무리를 가하기 때문에 접속반으로 모아 전달하는 방식으로 인버터의 고장을 줄일 수 있는 기능을 하고, 태양광 패널에 따라 차이나는 발전량에 대한 충돌을 방지하고 역전류를 방지해주는 기능을 한다.Because the connection panel connects the direct current generated from the solar panel directly to the inverter, it is loaded on the inverter because it puts the load on the inverter. It functions to reduce the failure of the inverter, and according to the solar panel, It prevents the collision against the generation amount and prevents the reverse current.
한편, 태양광 발전 접속반은 구조 자체가 습기에 취약한 구조로 설계되거나 그렇지 않더라도 전류측정을 위한 Shunt 접속부가 열화되어 절연파괴에 이르러 화재를 야기시키는 경우가 많았다. 이를 위하여, 태양광 발전 접속반에 발생되는 열을 방출시키고, 외부 습기, 먼지와 같은 취약요소를 차단시키는 개선된 구조에 대한 연구개발이 계속되었다.On the other hand, the photovoltaic connection panel is designed to have a structure that is vulnerable to moisture, or the shunt connection part for current measurement deteriorates to cause an insulation breakdown and cause a fire. To this end, research and development has been continued on an improved structure that releases heat generated in the photovoltaic module and blocks vulnerable elements such as external moisture and dust.
이와 관련하여, 종래의 기술을 살펴보면, 대한민국 등록특허공보 제10-1651069호에 개시된 바와 같이, 별도의 통풍구나 팬을 형성하지 않아 빗물이나 불순물의 침투로 인해 생길 수 있는 접속반의 고장을 미연에 방지하고, 접속반 내부의 열을 낮추기 위해 접속반 외부로 방열판을 노출시킨 태양광 발전용 접속반이 개시되었다. 그러나, 이는 태양광 발전 접속반의 방열효율을 높이기 위해 더 개선된 방열판 구조만을 채용하였을 뿐으로 보다 본질적으로 접속반의 방열 개선방안이 될 순 없었다.According to the related art, as disclosed in Korean Patent Publication No. 10-1651069, it is possible to prevent the breakage of the connection panel, which may be caused by the infiltration of rainwater or impurities, And a heat sink is exposed to the outside of the connection board to lower the heat inside the connection board. However, this method only adopted a more improved heat sink structure in order to increase the heat radiation efficiency of the photovoltaic connection module, and could not be a measure for improving the heat radiation of the connection board in essence.
또한, 종래의 태양광 발전용 접속반은 다이오드를 통해 출력되는 전력선의 일측에는 홀센서가 부착되어 개별 태양광 어레이가 발전하는 발전량을 모니터링할 수 있고, 다이오드가 결합된 방열판의 일측에는 온도센서가 부착되어 있어 방열판의 온도를 실시간 모니터링하여 태양광 어레이의 발전량에 대한 이상 유무를 감지함과 동시에 다이오드의 열화에 의한 파손 여부도 동시에 감지할 수 있으며, 접속반의 내부에는 온도센서와 소방설비가 설치되어 있고, 온도센서는 접속반 내부의 온도를 실시간 감지하며, 측정된 온도가 기준온도보다 높게 감지될 경우 제어부에서 화재 상황으로 인식하여 소방설비가 고체에어로졸을 분사하도록 하여 접속반 내에 발생한 화재를 소화하는 것을 특징으로 하였다. 이와 같이 화재를 미리 감지하여 예방하고 빠르게 진압하기 위한 접속반 내부의 제어부는 종래에 개시되었으나, 태양광 어레이의 발전량을 모니터링하는 홀센서에서 더 나아가, 태양광 어레이 주변의 환경을 감지하고 발전량을 향상시키거나 효율을 높이도록 자동으로 제어하는 인공지능형 태양광 발전 접속반이 요구된다.In addition, in the conventional solar cell connection panel, a hall sensor is attached to one side of a power line output through a diode to monitor an amount of power generation of an individual solar array, and a temperature sensor is attached to one side of a heat sink to which a diode is coupled It monitors the temperature of the heat sink by monitoring the temperature of the heat sink. It detects the abnormality with respect to the generation amount of the solar array and simultaneously detects whether the diode is damaged by the deterioration. A temperature sensor and a fire protection facility are installed inside the connection panel The temperature sensor senses the temperature inside the connection panel in real time. When the measured temperature is detected to be higher than the reference temperature, the controller recognizes it as a fire situation, and the fire control system injects the solid aerosol, . Although the control unit in the connection panel for detecting and preventing the fire in advance and suppressing the fire in advance has been disclosed in the past, the control unit further includes a hall sensor for monitoring the power generation amount of the solar array, further detects the environment around the solar array, And an artificial intelligent photovoltaic connection module that automatically controls the power supply to increase efficiency.

상기 케이스(100)는 상기 PCB 회로(200)와 상기 IoT 통신모듈(300)이 장착되는 하부케이스와, 상기 하부케이스에 구비된 체결홀들에 의해 결합되는 상부케이스(미도시)로 구성되며, 상기 PCB 회로(200)와 상기 IoT 통신모듈(300)을 보호하는 기능을 제공한다.The case 100 is composed of a lower case to which the PCB circuit 200 and the IoT communication module 300 are mounted and an upper case (not shown) coupled by fastening holes provided in the lower case, And provides a function of protecting the PCB circuit 200 and the IoT communication module 300.
상기 체결홀들은 도 1에 도시된 바와 같이 각 모서리에 한 개씩 구비되어 4개로 형성될 수 있으나, 상기 체결홀들의 개수 및 상기 케이스(100)의 형상은 한정적인 것이 아니다.As shown in FIG. 1, the fastening holes may be formed in four corners, but the number of fastening holes and the shape of the case 100 are not limited.
상기 PCB 회로(200)는 도 2에 도시된 바와 같이, 역전류방지다이오드(210)와 방열판(220)을 포함하여 구성된다. 상기 역전류방지다이오드(210)는 상기 방열판(220)에 부착된 형태로 설치된다.As shown in FIG. 2, the PCB circuit 200 includes a reverse current prevention diode 210 and a heat sink 220. The reverse current prevention diode 210 is attached to the heat sink 220.
상기 역전류방지다이오드(210)는 태양광 발전 시스템에 설치되는 다수 개의 태양광패널 간의 발전량 차이가 일정량 이상 발생할 때 상기 태양광패널 간의 충돌을 방지하기 위한 상기 태양광 발전 접속반(10)의 필수적인 구성요소 중 하나이다.The reverse current prevention diode 210 is an essential element of the photovoltaic generation connection panel 10 for preventing a collision between the solar panels when a power generation amount difference between a plurality of solar panels installed in the photovoltaic power generation system exceeds a predetermined amount It is one of the components.
또한, 상기 역전류방지다이오드(210)는 도 2에 도시된 바와 같이 2개로 구성될 수 있으나, 도 3에 도시된 바와 같이 1개로 구성될 수 있으며, 상기 역전류방지다이오드(210)의 개수는 이에 한정되지 않는다.2, the number of the reverse current prevention diodes 210 may be one, as shown in FIG. 3, and the number of the reverse current prevention diodes 210 may be one, But is not limited thereto.
상기 방열판(220)은 상기 역전류방지다이오드(210)로 인해 상기 태양광 발전 접속반(10) 내에 발생하는 열을 외부에 방출하기 위한 상기 태양광 발전 접속반(10)의 필수적인 구성요소 중 하나이다.The heat dissipation plate 220 is one of the essential components of the solar power generation connection panel 10 for discharging the heat generated in the solar power generation connection panel 10 to the outside due to the reverse current prevention diode 210 .
또한, 상기 방열판(220)은 도 2 내지 도 4에 도시된 바와 같이, 다수 개의 u자 형의 방열핀으로 구성되어 상기 태양광 발전 접속반(10) 내의 발열을 효율적으로 방출시킬 수 있도록 한다.2 to 4, the heat dissipation plate 220 may include a plurality of u-shaped heat dissipation fins, so that the heat generated in the solar power generation connection board 10 can be efficiently emitted.
또한, 도 4에 도시된 바와 같이, 상기 역전류방지다이오드(210)는 제1홀(211)을, 상기 방열판(220)은 제2홀(221)을 포함하여, 체결나사(230)를 통해 상기 역전류방지다이오드(210)와 상기 방열판(220)을 체결할 수 있도록 구성된다.4, the reverse current prevention diode 210 includes a first hole 211, the heat sink 220 includes a second hole 221, and a fastening screw 230 And is configured to fasten the reverse current prevention diode 210 and the heat sink 220.
특히, 태양광패널이 병렬로 구성된 접속반(10)의 경우, 상기 역전류방지다이오드(210)는 한 개의 스트링에 문제가 발생되어 전압이 다운될 경우 각 병렬로 연결된 나머지 정상적인 스트링과의 전압차로 인하여, 스트링의 전류가 역으로 넘어가는 것을 방지하는 기능을 하는데, 전압차가 클수록 상기 역전류방지다이오드(210)에 열화가 발생하여 접속반에 화재를 야기한다. 상기 열화를 방출시키는 방열특성을 획기적으로 개선시키기 위해 상기 케이스(210)와 상기 방열판(220)은 탄소 소재로, 바람직하게는 탄소섬유 강화플라스틱(CFRP; Carbon Fiber Reinforced Plastics)으로 설계된다.In particular, in the case of the connection board 10 in which solar panels are formed in parallel, the reverse current prevention diode 210 has a problem in a single string, and when a voltage is lowered, This prevents the string current from being reversed. The larger the voltage difference, the more deteriorated the reverse current prevention diode 210, causing a fire in the connection half. The case 210 and the heat dissipation plate 220 are made of carbon material, preferably carbon fiber reinforced plastic (CFRP), in order to drastically improve the heat dissipation property of releasing the deterioration.

It is used as an ingredient material. Carbon fiber reinforced carbon fiber (carbonfiber) is obtained by carbonization of rayon, acrylic fiber or pitch fiber, most of which is from acrylic fiber. Thermosetting epoxy resin is the most used as matrix resin. Polyimide resin is also used.
상기 케이스(210)와 상기 방열판(220)은 상기 탄소섬유 강화플라스틱으로 사출 성형되거나, 상기 탄소섬유 강화플라스틱으로 방열코팅되어 제조된다.The case 210 and the heat sink 220 may be injection-molded using the carbon fiber-reinforced plastic or may be coated with the carbon fiber-reinforced plastic.
