What is Shaanxi Pulse Capacitor? Xiaobian in this article to share

Two conductors close to each other are sandwiched between them with a non-conductive insulating medium, which constitutes a capacitor. When a voltage is applied between the two plates of a pulse capacitor, the capacitor will store an electric charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on a conducting plate to the voltage between the two plates.

The basic unit of capacitance of a capacitor is farad (F). In the pulse capacitor, the pulse capacitor of the pulse energy storage unit is an energy storage device used to increase the power pulse output signal.

In a pulsed power system, energy is stored in a relatively slow manner, and then in a pulsed power system, the energy is quickly transferred to the appropriate energy over a relatively short period of time.

The primary energy is to slowly charge the pulse energy storage unit to achieve energy storage, and then the pulse capacitor forms part of the stored energy through the pulse to compress and restructure the pulse of time size to achieve pulse power amplification. Then the load pulse waveform with peak power is obtained.

The pulse capacitor can store the charging energy of the capacitor from a small power supply in a long time interval, and at a certain moment when needed, the stored energy is quickly released in a very short time interval to form a strong impulse current and a strong impulse power.

There are two kinds of high-voltage pulse capacitors: one is thin film and one is ceramic. Compared with thin films, ceramics have higher voltage characteristics. The advantage of thin film capacitors is that their capacity is higher than that of ceramic capacitors.

The commonly used pulse ceramic capacitor is PC ceramic, the dielectric constant of 400 ceramic capacitor can work in the range of -55 degrees to +125 degrees, the temperature change rate is less than 5%, it has overvoltage characteristics and pulse characteristics. The current photoelectric military equipment and electromagnetic pulse military equipment mostly use PC materials. Its pulse life is over a million times.

Of course, there are also stage pulse capacitors. Many scientific research institutions choose N4700 ceramic materials as the wholesale of Shaanxi pulse capacitors. This material can also meet the needs of users to a certain extent, but if a large number of devices are used, the life expectancy is insufficient. The pulse life of such products in the capacitor industry is about 3,000 to 50,000.

In 2004, the industrial power brand "Leap" was born, and in the same year, it took the lead in passing the ISO9001 quality system and developed laser power supplies and photon power supplies with the same functional volume. After nearly 20 years of development and exploration, "Leap" now has laser power supply, high voltage power supply, pulse power supply, vacuum coating power supply, radio frequency power supply, special power supply and other industrial power products.

Our products are widely used in industry, medical, military, scientific research, communication, environmental protection and energy saving. There are already tens of thousands of power systems in operation.

The "transition" power supply has the characteristics of small size, simple use, multiple functions, complete varieties, protection, full CNC intelligent power supply, flexible control and so on. So far, the "Yueqian" brand is formed in Beijing as the headquarters, Shanghai, Suzhou as the branch, and the products radiate the whole China. In Europe, the United States, Japan also have "jump" power products.
