電解電容放置太久如果不能采用正確的激活方式會(huì)直接導(dǎo)致電解電容損壞，電解電容廠家告訴您：年久的電解電容正確的激活方法。大容量電解電容放置半年或者1年以上，在重新使用的使用時(shí)候，必須采用激活的辦法，才能使用，否則會(huì)導(dǎo)致?lián)p壞或者使用命。

　　If the electrolytic capacitor is placed too long, if the correct activation method can not be used, it will directly damage the electrolytic capacitor. The electrolytic capacitor manufacturer tells you: activating the electrolytic capacitor has become the key factor of its service life. If the large capacity electrolytic capacitor is stored for more than half a year or more, it must be activated before it can be used, otherwise it will cause damage or service life 。

　　如何將舊電解電容的激活？

　　How to activate the old electrolytic capacitor?

　　1、用萬用表電阻擋測(cè)量待激活的電解電容，當(dāng)正向電阻為零或者很小時(shí)，說明該電解電容已經(jīng)擊穿報(bào)廢。除此之外的電解電容都可以進(jìn)行激活處理。

　　When the positive resistance is zero or very small, it means that the electrolytic capacitor has been broken down and scrapped. In addition, all electrolytic capacitors can be activated.

　　2、將電解電容焊接好后，首先加半壓，以450V電解電容為例，可將市電電壓調(diào)至130V，此時(shí)電解電容兩端的直流電壓是130Vx1.4=180V左右，激活24小時(shí)。

　　After welding the electrolytic capacitor, first add half voltage. Taking 450V electrolytic capacitor as an example, the commercial voltage can be adjusted to 130v. At this time, the DC voltage at both ends of the electrolytic capacitor is about 130vx1.4 = 180V, which is activated for 24 hours.

　　3、然后斷開交流電源，用一只5W300Ω的電阻搭接在電解電容器兩端放電，注意一定要放完。

　　Then disconnect the AC power supply, and use a 5w300 Ω resistor to lap the two ends of the electrolytic capacitor for discharge. Pay attention to the discharge.

　　4、用電容表測(cè)量容量的恢復(fù)情況，．一般都能恢復(fù)60％左右。對(duì)于容量一點(diǎn)都沒有恢復(fù)的，可以基本判斷該電解電容已經(jīng)斷路損壞。

　　Measuring the recovery of capacity with a capacitance meter, it can recover about 60% in general. For the capacity has not recovered at all, it can be basically judged that the electrolytic capacitor has been broken.

　　5、將電壓調(diào)至220V，此時(shí)電解電容兩端的直流電壓是220Vx1.4=300V左右，繼續(xù)激活24小時(shí)，此時(shí)容量能夠恢復(fù)到90％～100％。

　　When the voltage is adjusted to 220 V, the DC voltage at both ends of the electrolytic capacitor is about 220 V x 1.4 = 300 v. after 24 hours of activation, the capacity can be restored to 90% - 100%.

　　6、將電壓調(diào)至350V，此時(shí)電解電容兩端的直流電壓是350Vx1.4=490V左右，繼續(xù)激活．48小時(shí)或者72小時(shí)。每次激活的電解電容數(shù)量不限。

　　6. When the voltage is adjusted to 350 V, the DC voltage at both ends of the electrolytic capacitor is about 350 V x 1.4 = 490 V, and it will continue to be activated for 48 hours or 72 hours. The number of electrolytic capacitors activated each time is unlimited.

　　經(jīng)過以上激活處理的電解電容，一般都能恢復(fù)到標(biāo)稱容量，并且漏電極小。

　　After the above activation treatment, the electrolytic capacitor can generally recover to the nominal capacity, and the leakage electrode is small.

　　激活大容量電解電容的辦法，有以下幾種方式：

　　There are several ways to activate large capacity electrolytic capacitor

　　1、加20%的額定電壓，工作1小時(shí)，然后斷電、放電；

　　Add 20% rated voltage, work for 1 hour, then power off and discharge;

　　2、加40%的額定電壓，工作1小時(shí)，然后斷電、放電；

　　Add 40% rated voltage, work for 1 hour, then power off and discharge;

　　3、加60%的額定電壓，工作1小時(shí)，然后斷電、放電；

　　Add 60% rated voltage, work for 1 hour, then power off and discharge;

　　4、加80%的額定電壓，工作1小時(shí)，然后斷電、放電；

　　Add 80% rated voltage, work for 1 hour, then power off and discharge;

　　5、加100%的額定電壓，工作1小時(shí)，然后斷電、放電。

　　Add 100% rated voltage, work for 1 hour, then power off and discharge.
