What kind of 主词六替换 will be higher(4)

Electrolytic capacitors, aluminum electrolytic capacitors and monolithic gallbladders, which use sulfuric acid to make the insulating medium, large capacity can carry out smaller volumes for the above, and are marked with a + sign, some are marked with a mark, generally do low cross-linking and side-by-side Circuit filter with larger loss meson, integral aluminum electrolytic capacitor, due to the shortcomings of using special materials, the electrolytic performance is better than ordinary, the preferred frequency, but can not do too much capacity, it can be used to accurately circuits, such as oscillators, or timing circuits.

主词六替换Five: aging and batch test high temperature aging test

rectangular wave of 20 kHz.
Due to the poor working conditions of the welding machine power supply and frequent short-circuit, arcing and open-circuit changes, the working reliability of the high-frequency inverter rectifier welding machine power supply has become the most critical issue and the most concerned issue by users. . The microprocessor is used as the relevant controller of pulse width modulation (PWM), and through the extraction and analysis of multi-parameter and multi-information, the purpose of predicting various working states of the system is achieved, and then the system is adjusted and processed in advance to solve the problem. The reliability of high-power IGBT inverter power supply is improved.
Foreign inverter welding machines can achieve a rated welding current of 300A, a load duration rate of 60%, a full-load voltage of 60~75V, a current adjustment range of 5~300A, and a weight of 29kg.

No matter how good the material and production technology process control of the product is, it is necessary to detect the aging of the equipment. Because the incoming inspection of electronic components and transformers is difficult to control, only by improving the aging and high-temperature sampling of the entire batch of power supplies can we detect whether the quality stability and material management of this batch of power supplies have potential safety risks.
