Working temperature and spontaneous heat (applicable to the B / E / F property). The surface temperature of the capacitor should be kept below the upper limit of its rated operating temperature range. It is important to take into account the inherent heat of the capacitor. The capacitor is at high f

Working voltage:When using a DC rated voltage capacitor in an AC circuit or a ripple current circuit, be sure to maintain the Vp-p value of the applied voltage or the Vo-p value containing the DC bias voltage within the rated voltage range. If a voltage is applied to the circuit, a temporary abnorma

When the capacitor bank adopts fuse protection (the drop fuse must be used, the capacitor itself is affected by a barrier or overvoltage of the system, etc., all of these will make the capacitor bank fuse. Once the capacitor fuse a wire, it will cause the three-phase current indication to be out of

In general, the capacitance doesn't make a loud noise when it's running, a bit like the buzzing sound of a bee's cauliflower. However, there are still some anomalies, mainly:(1) The discharge sound caused by the loosening of the connection between the capacitor busbar and the conductive bar; (2) Dis

The temperature of the capacitor and the temperature of the shell is limited, but there are some reasons why the temperature of the capacitor is too high:(1) Because of the unreasonable design of the capacitor chamber, the ambient temperature of the capacitor chamber is too high; (2) The density of

After dedusting of circuit board and bus bar, necessary anticorrosion treatment is carried out, insulating paint is painted, and burr must be removed after partial discharge and arc pulling are used. The damaged part of the insulating board which has been insulated and broken shall be removed, the i

Open the front door of the converter, open the back door, carefully check whether the AC or DC bus row is deformed, corroded and oxidized, whether the screw at the bus joint is loose or not, and whether the solid screw at the fixing point is loosened. Fixed insulation or insulation column with or wi

Dedusting frequency converter regularly, the emphasis is rectifier cabinet, inverter cabinet and control cabinet, if necessary, the rectifier module, inverter module and control cabinet can be removed from the circuit board after dust removal. Frequency converter down air inlet, upper air outlet whe

Regular dust removal check fan inlet is blocked. Monthly cleaning air filter cooling duct and internal dust.Regular inspection, should be carried out once a year: check screws, bolts and that is, plug-in, etc., whether the input-output reactor ground and phase resistance short-circuit phenomenon, no
