根據(jù)國際常用標(biāo)準(zhǔn),牛角鋁電解電容使用時溫度每降低7度,壽命增加一倍。因此牛角鋁電解電容器的使用壽命主要取決于牛角型鋁電解電容的內(nèi)部溫度,同一條件下牛角電容芯溫越低使用壽命越長。
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.
所以很多采購商經(jīng)??紤]的一個問題就是牛角鋁電解電容的使用壽命,山東紅寶電子有限公司小編給大家詳解一下如何增加牛角鋁電解電容的使用壽命。
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、選擇高質(zhì)量的牛角型鋁電解電容生產(chǎn)廠家
1、 Choose high quality aluminum electrolytic capacitor manufacturers
同一款牛角鋁電解電容器,生產(chǎn)廠家不同,質(zhì)量會有所區(qū)別,價格也會相差很大。大部分的采購人員都會優(yōu)先去評比價格,牛角型鋁電解電容的壽命是有限的,壽命越長,性價比越高,應(yīng)該正確的認識到質(zhì)量比價格更重要,高質(zhì)量的牛角型鋁電解電容電性能穩(wěn)定、使用壽命長,遠比購買低價的要劃算。
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、正確的選擇牛角鋁電解電容規(guī)格型號
2、 Correct selection of specifications and models of horn electrolytic capacitor
在實際應(yīng)用中,牛角電解電容的使用電壓、紋波電流、開關(guān)頻率都會直接影響到牛角電解電容壽命。在使用時浪涌電壓和瞬時高電壓是經(jīng)常出現(xiàn)的,一般牛角電解電容在額定電壓的1.34倍電壓下,1個小時候就會出現(xiàn)漏液、底部沖開等現(xiàn)象,主要是由于浪涌電壓和瞬時高電壓造成的損壞,所以,牛角電解電容的電壓選擇都會進行降額,降到額定電壓的80%使用較為合理。
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、正確的安裝牛角鋁電解電容器
3、 Correct installation of horn aluminum electrolytic capacitor
牛角鋁電解電容器使用溫度越高,電解液蒸發(fā)速度越快,當(dāng)電解液的量減少到一定極限時,電容壽命也就終止了。
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.
在安裝時我們就要考慮到以下4點:
When installing, we should consider the following four points:
1、避免安裝在密封環(huán)境中。
1. Avoid installation in a sealed environment.
2、安裝時遠離與其他發(fā)熱元件。
2. Keep away from other heating elements during installation.
3、條件允許的情況下,加裝散熱裝置。
3. If conditions permit, install heat sink.
4、焊接時溫度與時間也要控制好。
4. The temperature and time should be well controlled during welding.
正常情況下按照以上的情況使用牛角鋁電解電容即可保證其使用壽命。更多關(guān)于電解電容型號及使用疑問歡迎聯(lián)系紅寶電子。
