空調(diào)電容器是由鋁圓筒做負極，里面裝有液體電解質(zhì)，插入一片彎曲的鋁帶做正極而制成的電容器?？照{(diào)電容器的存在是左右其是否能夠正常工作以及工作效率的關(guān)鍵所在。

　　Air conditioning capacitor is made of aluminum cylinder as negative electrode, which is filled with liquid electrolyte and inserted into a bent aluminum strip as positive electrode. The existence of air conditioning capacitor is the key to whether it can work normally and work efficiency.

　　對于空調(diào)電容的選擇必需要了解一定的常識，不可盲目選擇。接下來電解電容廠家就給大家分享一下選擇空調(diào)電容的基礎(chǔ)常識。

　　For the selection of Air Conditioning Capacitor must understand certain common sense, can not be blindly selected. Next, let's take a look at the basic knowledge of selecting air conditioning capacitors.

　　空調(diào)電容器的芯子是由陽極鋁箔、浸有電解液的襯墊紙、陰極鋁箔、天然氧化膜等重疊卷繞而成的，芯子含浸電解液后用鋁殼和膠蓋密閉起來就構(gòu)成一個空調(diào)電容器。一般情況下，空調(diào)電容器的鋁殼外面都有一個塑料套管。

　　The core of air conditioning capacitor is composed of anode aluminum foil, backing paper soaked with electrolyte, cathode aluminum foil, natural oxide film, etc. the core of air conditioner capacitor is composed of aluminum shell and rubber cover after being immersed in electrolyte. In general, there is a plastic sleeve outside the aluminum shell of the air conditioner capacitor.

　　電容在電路中實際要承受的電壓不能超過它的耐壓值。在濾波電路中，電容的耐壓值不要小于交流有效值的1.42倍。使用電解電容的時候，還要注意正負極不要接反。

　　The actual voltage that the capacitor should bear in the circuit should not exceed its withstand voltage value. In the filter circuit, the withstand voltage value of capacitor should not be less than 1.42 times of AC effective value. When using electrolytic capacitor, pay attention not to connect the positive and negative poles in reverse.

　　電容在裝入電路前要檢查它有沒有短路、斷路和漏電等現(xiàn)象，并且核對它的電容值。安裝的時候，要使電容的類別、容量、耐壓等符號容易看到，以便核實。

　　Before installing the capacitor into the circuit, check whether it has short circuit, open circuit and leakage, and check its capacitance value. When installing, make the type, capacity, withstand voltage and other symbols easy to see for verification.

　　不同電路應(yīng)該選用不同種類的電容?？窕芈房梢赃x用云母、高頻陶瓷電容，隔直流可以選用紙介、滌綸、云母、電解、陶瓷等電容，濾波可以選用電解電容，旁路可以選用滌綸、紙介、陶瓷、電解等電容。

　　Different types of capacitors should be selected for different circuits. Mica and high-frequency ceramic capacitors can be used for wiping vibration circuit, paper dielectric, polyester, mica, electrolysis and ceramic capacitors can be selected for DC isolation, electrolytic capacitors can be selected for filtering, and polyester, paper dielectric, ceramic, electrolytic capacitors can be selected for bypass.

　　空調(diào)電容器是空調(diào)正常運轉(zhuǎn)必不可缺的電子元器件，所以在選擇的時候必須要謹慎選擇，根據(jù)空調(diào)的型號、功率等特征選擇適合的電容型號。

　　The capacitor of air conditioner is an indispensable part of the whole operation of the air conditioner. Therefore, it is necessary to select the appropriate capacitor model according to the characteristics of air conditioner model and power.
