1、 Structural features
1. Small size, light weight, easy installation, using high-quality metallized polypropylene film as the medium, and unique structural design make the capacitor volume and weight only 1/4 and 1/5 of the old product;
2. Low loss, low heat generation, low temperature rise, and the use of new spray gold technology and unique metallized film edge thickening technology greatly enhance the capacitor's anti surge ability, stable performance, greatly extend its working life, and reduce the capacitor's own consumption. The actual value is less than 0.08%, with less heat generation, low temperature rise, and excellent energy-saving effect:
3. Excellent self-healing performance, rapid self-healing of local dielectric breakdown, restoration of normal operation, greatly improving reliability:
4. Safety, built-in self discharge resistor and safety device, ensuring safe and reliable use;
5. No oil leakage, green and environmentally friendly, Microcrystalline wax is used as the impregnating agent, which is solid at room temperature, and the dropping point is higher than 70C. There is no oil leakage during use, which avoids environmental pollution. It not only has the characteristics of dry structure, but also has the advantages of impregnating capacitors. In addition, the unique impregnation process makes the operation of capacitors more reliable;
6. The corrosion-resistant and anti-counterfeiting shell is beautiful and sturdy. The printed iron shell has undergone special double anti-corrosion treatment, greatly improving its corrosion resistance. The unique anti-counterfeiting design is exquisite and beautiful.
2、 Working conditions
1. After the capacitor is cut off from the power supply, it is necessary to ensure that the remaining voltage of the capacitor drops to 10% of the rated voltage before allowing it to be put into operation again. Generally, this time takes about 200s, so the controller should choose a controller with the function of switching back on and locking time after cutting off. If a general controller is used, additional fast discharge facilities need to be installed. For those using equipotential switching switches, this limitation is not applicable.
2. The sea level shall not exceed 2000m.
3. Environmental temperature category -25C, minimum temperature -25C, maximum temperature category C, (maximum not exceeding 50C, average temperature within 24 hours not exceeding 40C, average temperature within a year not exceeding 30C). Capacitors should be ensured to operate under good ventilation conditions and are not allowed to operate in a closed and non ventilated environment.
