如何避免電源適配器短路的風(fēng)險？
When summer comes, the weather is slowly getting hot. At the same time, it is the season of frequent fires, and many fires are caused by the short circuit of the power adapter. So how to avoid the risk of short circuit of the power adapter and ensure safe charging?
夏天到了，天氣慢慢變熱了。同時，又是火災(zāi)多發(fā)的季節(jié)，很多火災(zāi)都是由電源適配器短路引起的。那么如何避免電源適配器短路的風(fēng)險，確保充電安全呢？
1. Avoid excessive voltage and current避免電壓和電流過大
Short circuit burning of mobile phone charger may also be the reason for using a socket with too high voltage or excessive external current. If the external current is too large, it will sometimes cause the output short circuit or input short circuit of power overcurrent protection. Therefore, it is best to use a suitable voltage socket for charging.
手機(jī)充電器短路燒壞也可能是使用電壓過高或外部電流過大的插座的原因。如果外部電流過大，有時會導(dǎo)致電源過電流保護(hù)的輸出短路或輸入短路。因此，最好使用合適的電壓插座進(jìn)行充電。
2. Buy original charger購買原裝充電器
The necessity of buying the original charger and using the original mobile phone charger. In a mobile phone store, the shopkeeper took out a mobile phone charger without brand, certification and instructions. When the reporter questioned its safety performance, the store said, "if you are afraid of an accident, you will buy the original factory. Cheap things must be cheap."
購買原裝充電器和使用原裝手機(jī)充電器的必要性。在一家手機(jī)店，店主拿出一個沒有品牌、沒有認(rèn)證、沒有說明書的手機(jī)充電器。當(dāng)記者質(zhì)疑其安全性能時，該店表示，“如果你害怕發(fā)生事故，你會購買原廠產(chǎn)品。一分價錢一分貨。
3. 3C certified products must be selected必須選擇3C認(rèn)證產(chǎn)品
"3C" is the national unified mark for compulsory product certification. The certified power adapter meets the requirements of national mandatory standards in terms of electrical safety and electromagnetic compatibility. This kind of charger has sufficient materials and mature technology, and has multiple protections such as overcurrent, overvoltage, short circuit and over temperature.
“3C”是國家統(tǒng)一的強(qiáng)制性產(chǎn)品認(rèn)證標(biāo)志。經(jīng)認(rèn)證的電源適配器在電氣安全和電磁兼容性方面符合國家強(qiáng)制性標(biāo)準(zhǔn)的要求。這種充電器材料充足，技術(shù)成熟，具有過電流、過電壓、短路、超溫等多重保護(hù)。
At the same time, in the process of use, this kind of charger has high charging efficiency and guaranteed safety. The authenticity of "3C" logo can be queried on the website of CNCA. This can avoid the possibility of buying a fake charger.
同時，在使用過程中，這種充電器充電效率高，安全性有保障?！?C”標(biāo)識的真實性可在中國質(zhì)監(jiān)委網(wǎng)站查詢。這樣可以避免購買假冒充電器的可能性。
