目前有一種新型的發(fā)電方式，就是太陽(yáng)能光伏發(fā)電，太陽(yáng)能光伏發(fā)電的原理就是把光能轉(zhuǎn)換成電能。太陽(yáng)能光伏發(fā)電目前是國(guó)家重點(diǎn)推廣的一種綠色的新能源，很多人擔(dān)心太陽(yáng)能光伏發(fā)電會(huì)有輻射，對(duì)人體是有危害的，真相是什么呢？接下來(lái)我們一起來(lái)了解一下吧。

太陽(yáng)能光伏發(fā)電有輻射嗎？光伏發(fā)電對(duì)人體有危害嗎？

如果說(shuō)太陽(yáng)能發(fā)電沒有輻射，是不可能的，其實(shí)太陽(yáng)能光伏發(fā)電是有些電磁輻射的，這個(gè)輻射并不是很多，非常的少。如果太陽(yáng)能光伏發(fā)電設(shè)備合格，所產(chǎn)生的輻射不會(huì)對(duì)人體造成危害，且這一點(diǎn)輻射，也不會(huì)對(duì)其他設(shè)備造成影響和干擾。

光伏發(fā)電是通過(guò)半導(dǎo)體的特性將光能直接轉(zhuǎn)換為直流電，再通過(guò)逆變器將直流電轉(zhuǎn)換為我們可以使用的交流電。光伏系統(tǒng)由光伏組件、支架、直流電纜、逆變器、交流電纜、配電柜、變壓器等組成，支架不帶電，自然不會(huì)產(chǎn)生電磁干擾。

光伏組件和直流電纜中含有直流電流，方向不變。它們只能產(chǎn)生電場(chǎng)，而不能產(chǎn)生磁場(chǎng)。雖然輸出變壓器是交流電，但是頻率很低，只有50Hz，產(chǎn)生的磁場(chǎng)也很低。逆變器是將直流電轉(zhuǎn)換成交流電的裝置。它包含電力電子轉(zhuǎn)換，頻率一般為5-20KHz，因此會(huì)產(chǎn)生交變電場(chǎng)，因此也會(huì)產(chǎn)生電磁輻射。但國(guó)家對(duì)光伏逆變器的電磁兼容性有著嚴(yán)格的標(biāo)準(zhǔn)。與家用電器相比，光伏逆變器的電磁輻射與筆記本電腦差不多，低于電磁爐、電吹風(fēng)、冰箱等。
Does solar PV have radiation? Is photovoltaic power generation harmful to the human body?

If solar power generation has no radiation, it is impossible, in fact, solar photovoltaic power generation has some electromagnetic radiation, this radiation is not very much, very little. If the solar photovoltaic power generation equipment is qualified, the radiation generated will not cause harm to the human body, and this radiation will not affect and interfere with other equipment.

Photovoltaic power generation is the direct conversion of light energy into direct current through the characteristics of semiconductors, and then the conversion of direct current into alternating current that we can use through the inverter. The photovoltaic system is composed of photovoltaic modules, brackets, DC cables, inverters, AC cables, distribution cabinets, transformers, etc., and the brackets are not charged and naturally do not produce electromagnetic interference.

PV modules and DC cables contain DC currents in the same direction. They can only generate electric fields, not magnetic fields. Although the output transformer is alternating current, the frequency is very low, only 50Hz, and the magnetic field generated is also very low. An inverter is a device that converts direct current into alternating current. It contains power electronic conversion, the frequency is generally 5-20KHz, so it generates an alternating electric field, so it also generates electromagnetic radiation. However, the country has strict standards for the electromagnetic compatibility of photovoltaic inverters. Compared with household appliances, the electromagnetic radiation of photovoltaic inverters is similar to that of laptops, and lower than that of induction cookers, hair dryers, refrigerators, etc.
