空调电容器是由铝圆筒做负极，里面装有液体电解质，插入一片弯曲的铝带做正极而制成的电容器。空调电容器的存在是左右其是否能够正常工作以及工作效率的关键所在。

　　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.

　　对于空调电容的选择必需要了解一定的常识，不可盲目选择。接下来电解电容厂家就给大家分享一下选择空调电容的基础常识。

　　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.

　　空调电容器的芯子是由阳极铝箔、浸有电解液的衬垫纸、阴极铝箔、天然氧化膜等重叠卷绕而成的，芯子含浸电解液后用铝壳和胶盖密闭起来就构成一个空调电容器。一般情况下，空调电容器的铝壳外面都有一个塑料套管。

　　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.

　　电容在电路中实际要承受的电压不能超过它的耐压值。在滤波电路中，电容的耐压值不要小于交流有效值的1.42倍。使用电解电容的时候，还要注意正负极不要接反。

　　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.

　　电容在装入电路前要检查它有没有短路、断路和漏电等现象，并且核对它的电容值。安装的时候，要使电容的类别、容量、耐压等符号容易看到，以便核实。

　　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.

　　不同电路应该选用不同种类的电容。揩振回路可以选用云母、高频陶瓷电容，隔直流可以选用纸介、涤纶、云母、电解、陶瓷等电容，滤波可以选用电解电容，旁路可以选用涤纶、纸介、陶瓷、电解等电容。

　　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.

　　空调电容器是空调正常运转必不可缺的电子元器件，所以在选择的时候必须要谨慎选择，根据空调的型号、功率等特征选择适合的电容型号。

　　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.
