根据国际常用标准，牛角铝电解电容使用时温度每降低7度，寿命增加一倍。因此牛角铝电解电容器的使用寿命主要取决于牛角型铝电解电容的内部温度，同一条件下牛角电容芯温越低使用寿命越长。

　　According to the international standard, the service life of ox horn electrolytic capacitor is doubled when the temperature is reduced by 7 degrees. Therefore, the service life of the horn aluminum electrolytic capacitor mainly depends on the internal temperature of the horn aluminum electrolytic capacitor. Under the same conditions, the lower the core temperature, the longer the service life.

　　所以很多采购商经常考虑的一个问题就是牛角铝电解电容的使用寿命，山东红宝电子有限公司小编给大家详解一下如何增加牛角铝电解电容的使用寿命。

　　So a lot of buyers often consider a problem is the service life of Niujiao electrolytic capacitor, Shandong Hongbao Electronic Co., Ltd. will explain in detail how to increase the service life of Niujiao electrolytic capacitor.

　　一、选择高质量的牛角型铝电解电容生产厂家

　　1、 Choose high quality aluminum electrolytic capacitor manufacturers

　　同一款牛角铝电解电容器，生产厂家不同，质量会有所区别，价格也会相差很大。大部分的采购人员都会优先去评比价格，牛角型铝电解电容的寿命是有限的，寿命越长，性价比越高，应该正确的认识到质量比价格更重要，高质量的牛角型铝电解电容电性能稳定、使用寿命长，远比购买低价的要划算。

　　The same ox horn aluminum electrolytic capacitor, different manufacturers, quality will be different, the price will be very different. Most of the purchasing staff will give priority to the evaluation of the price. The service life of the horn type aluminum electrolytic capacitor is limited. The longer the service life is, the higher the cost performance ratio is. The quality is more important than the price. The high-quality horn aluminum electrolytic capacitor has stable electrical performance and long service life, which is far more cost-effective than the low-cost one.

　　二、正确的选择牛角铝电解电容规格型号

　　2、 Correct selection of specifications and models of horn electrolytic capacitor

　　在实际应用中，牛角电解电容的使用电压、纹波电流、开关频率都会直接影响到牛角电解电容寿命。在使用时浪涌电压和瞬时高电压是经常出现的，一般牛角电解电容在额定电压的1.34倍电压下，1个小时候就会出现漏液、底部冲开等现象，主要是由于浪涌电压和瞬时高电压造成的损坏，所以，牛角电解电容的电压选择都会进行降额，降到额定电压的80％使用较为合理。

　　In practical application, the voltage, ripple current and switching frequency of the electrolytic capacitor will directly affect the life of the electrolytic capacitor. In use, surge voltage and instantaneous high voltage often occur. Generally, under the voltage of 1.34 times of rated voltage, the phenomenon of liquid leakage and bottom flushing will occur in an hour. The main reason is the damage caused by surge voltage and instantaneous high voltage. Therefore, the voltage selection of horn electrolytic capacitor will be reduced to 80% of the rated voltage Reason.

　　三、正确的安装牛角铝电解电容器

　　3、 Correct installation of horn aluminum electrolytic capacitor

　　牛角铝电解电容器使用温度越高，电解液蒸发速度越快，当电解液的量减少到一定极限时，电容寿命也就终止了。

　　The higher the operating temperature is, the faster the evaporation rate of electrolyte is. When the amount of electrolyte is reduced to a certain limit, the life of capacitor will be terminated.

　　在安装时我们就要考虑到以下4点：

　　When installing, we should consider the following four points:

　　1、避免安装在密封环境中。

　　1. Avoid installation in a sealed environment.

　　2、安装时远离与其他发热元件。

　　2. Keep away from other heating elements during installation.

　　3、条件允许的情况下，加装散热装置。

　　3. If conditions permit, install heat sink.

　　4、焊接时温度与时间也要控制好。

　　4. The temperature and time should be well controlled during welding.

　　正常情况下按照以上的情况使用牛角铝电解电容即可保证其使用寿命。更多关于电解电容型号及使用疑问欢迎联系红宝电子。
