1）薄膜电容的额定电压必须与本地区电网电压相符合，对于某些电压过高或者有谐波存在的电网，由于高次谐波，尤其是三、五、七次谐波，能量大的，危害也属于较强，在配置时，应采取措施予以避免和隔离。
1) The rated voltage of the film capacitor must be in line with the local power grid voltage. For some power grids with high voltage or harmonics, due to the high-order harmonics, especially the third, fifth and seventh harmonics, the harm is also strong. In the configuration, measures should be taken to avoid and isolate them.
2）注意运行环境温度。由于过高的运行温度会导致薄膜电容的电化学反应加剧，影响自愈时的热量消散，将导致自愈失败或使用寿命短缩，因此，安装薄膜电容器时应避开热源，改善散热及通风环境。2) Pay attention to the operating ambient temperature. Due to the high operating temperature will lead to the intensification of electrochemical reaction of the film capacitor, affect the heat dissipation during self-healing, and lead to self-healing failure or short service life. Therefore, the installation of thin-film capacitor should avoid heat source, improve the cooling and ventilation environment.
3）电容器柜应设有合理的保护装置：
3) The capacitor cabinet shall be equipped with reasonable protection device:
①调整合适的延时及放电时间，投入与切除电容器组要配有限流及放电装置。因为薄膜电容内阻小，浪涌电流可能高达上万安倍，为了防止新投入的电容器受到旁侧先投入的电容器对其放电，所以应设置限流保护装置；为了保证运行及维护薄膜电容的安全，必须设置放电装置；① Adjust the appropriate time delay and discharge time. The capacitor bank should be equipped with limited current and discharge device. Because the internal resistance of the film capacitor is small, the surge current may be as high as tens of thousands of ampere times. In order to prevent the newly put in capacitor from being discharged by the capacitor first put in at the side, the current limiting protection device should be set; in order to ensure the safety of operation and maintenance of the film capacitor, the discharge device must be set up;
②投切程序应遵守先投先切，后投后切的原则；
② The switching procedure should follow the principle of first switching and then switching;
③为了防止频繁投切，电容器组在切除时必须保留足够容量，作为基数组。
③ In order to prevent frequent switching, the capacitor bank must reserve enough capacity as the base group. |
