What is the function of the supercapacitor in Super Farad?

Power capacitors are a type of reactive power compensation device. The load and power supply equipment of the power system, such as motors, transformers, transformers, etc., not only consume active power, but also "absorb" reactive power. If all these reactive power are supplied by generators, it will inevitably affect its active power output, which is not only uneconomical, but also causes poor voltage quality and affects user usage.

Capacitors can generate reactive power (capacitor current) under the action of AC voltage. If capacitors are connected in parallel to a load (such as an electric motor) or power supply equipment (such as a transformer) for operation, the reactive power that the load or power supply equipment needs to absorb is supplied by the reactive power generated by the capacitors, which is called parallel compensation. Parallel compensation reduces line energy loss, improves voltage quality, increases power factor, and enhances system power supply capacity.

If capacitors are connected in series on the line to compensate for line reactance and change line parameters, this is called series compensation. Series compensation can reduce line voltage loss, increase the voltage level at the end of the line, reduce power and energy losses in the power grid, and improve transmission capacity.

Power capacitors include phase-shifting capacitors, electric heating capacitors, voltage sharing capacitors, coupling capacitors, pulse capacitors, etc. Phase shifting capacitors are mainly used to compensate for reactive power and improve the power factor of the system; Electric thermal capacitors are mainly used to improve the power factor of intermediate frequency power systems; Equalizing capacitors are generally connected in parallel to the break of circuit breakers for voltage balancing purposes; Coupling capacitors are mainly used for communication, measurement, control, and protection of power transmission lines; Pulse capacitors are mainly used for pulse circuits and DC high-voltage rectification and filtering.

With the development of the national economy, the load is increasing day by day, the power supply capacity is expanding, and reactive power compensation work must keep up accordingly. When using capacitors as reactive power compensation, the investment is low, the loss is small, it is easy to install separately, and it is widely used. Of course, due to the requirement of system stability, a certain proportion of phase-shifting cameras must be equipped. So what applications can Super Farad capacitors be used in the industry for?

1. Flashlight

It is very frustrating to find that flashlights are becoming increasingly dim and dull in emergency situations, as the battery's lifespan has reached. Even modern flashlights require several hours to fully charge, and the battery cycle life is very short.

All of this about batteries could become history. A flashlight that uses supercapacitors instead of batteries as energy storage components, with a charging time of only 90 seconds and a cycle life of up to 500000 times. If you use one charging and discharging cycle every day, it can last for about 135 years.

This tactical flashlight is developed for professional users, mainly police and military.

2. DC screen energy storage system

DC screen energy storage system

As a power supply, DC screens play a very important role in power supply systems such as substations, power plants, large and medium-sized factories and mining enterprises. They are mainly used to supply power to the transmission mechanisms of control, protection, communication equipment, automatic device operation machinery, and adjustment machinery. At the same time, they can also serve as independent accident lighting power sources. Therefore, their performance and reliability directly affect the normal and safe operation of the entire power supply system.

The DC screen composed of batteries can store a large amount of electrical energy to achieve long-term DC supply during power outages. It is widely used in some important substations (such as 110kV and above substations). However, some unimportant terminal and user stations do not actually require long-term DC power supply after a power outage, but only require DC power during opening and closing operations. Considering the use of battery type DC screens to ensure the reliability of accident opening, it inevitably brings high operating costs, and the equipment requires frequent maintenance and has a short service life. In addition, the failure rate also increases due to the multiple series connections of its batteries. If any battery has a problem, it will affect the normal operation of the entire battery pack, and discarded batteries bring great harm to the environment. Due to the problems with the aforementioned devices, people urgently hope for better solutions. The emergence of super Faraday capacitors and their excellent performance bring hope for solving this problem.

Compared to batteries, supercapacitors have many advantages that batteries cannot match.

(1) Has a very high power density.

(2) Fast charging speed.

(3) Long service life.

(4) Superior low-temperature performance.

(5) The materials used in supercapacitors are safe, non-toxic, environmentally friendly, and maintenance free. And batteries require regular maintenance, and discarded batteries pose a great threat to the environment.
