What are the characteristics of smart capacitors

The intelligent capacitors produced by intelligent capacitor manufacturers integrate advanced technologies such as modern measurement and control, power electronics, network communication, automatic control, and power capacitors. It has changed the outdated controller technology of traditional reactive power compensation devices and the outdated switching technology of mechanical contactors or electromechanical integrated switches as capacitors. Changing the cumbersome and bulky structure of traditional reactive power compensation devices, the new generation of low-voltage reactive power compensation devices have the characteristics of better compensation effect, smaller size, lower power consumption, lower price, more cost saving, more flexible use, more convenient maintenance, longer lifespan, and higher reliability, adapting to the higher requirements of modern power grids for reactive power compensation.
The intelligent capacitors of intelligent capacitor manufacturers adopt modular design, consisting of capacitors, intelligent measurement and control modules, switch modules, line protection modules, and human-machine interface modules.
The basic functions of smart capacitors from smart capacitor manufacturers are: smart capacitors can be used individually or multiple devices can be used online. It is not the traditional automatic reactive power compensation device composed of intelligent controller, fuse, compound switch or mechanical contactor, thermal relay, low-voltage power capacitor, indicator light and other wires.
Before the emergence of smart capacitors from smart capacitor manufacturers, traditional reactive power compensation devices were mainly used in enterprise power supply systems. However, traditional compensation devices have high requirements for environmental temperature, voltage, and current, which brings a lot of workload to maintenance personnel of the power supply system. Unlike traditional compensation devices, intelligent capacitors have built-in multiple protection functions to ensure their stable operation. There are multiple forms at the same time, such as intelligent capacitors switched by composite switches, intelligent capacitors switched by synchronous switches, etc.
Advantages of smart capacitors from smart capacitor manufacturers: Smart capacitors not only have built-in protection functions, but also have functions such as intelligent networking, background monitoring, and human-machine interaction. These functions are not possessed by traditional reactive power compensation devices.
The disadvantage of smart capacitor manufacturers' smart capacitors is that in harmonic control environments, the filtering reactor will be integrated inside the smart capacitor. But when the reactor is running, it will generate heat, which can affect the operation of smart capacitors in some cases and damage them in others.
Performance characteristics of smart capacitors from smart capacitor manufacturers:
1. Modular structure. The intelligent capacitor adopts a modular structure, with small size, simple on-site wiring, and convenient maintenance. The expansion of the reactive power compensation system can only be achieved by increasing the number of modules.
2. High quality capacitors. Adopting self-healing low-voltage compensation capacitors with built-in temperature sensors to reflect the internal heating degree of the capacitors and achieve over temperature protection.
3. Embedded switch module. Intelligent capacitor manufacturers have built-in switch modules for their smart capacitors. The switching module is composed of thyristors, magnetic holding relays, zero crossing trigger conduction circuits, and thyristor protection circuits, achieving "zero switching" of capacitors and ensuring no inrush current and overvoltage during the switching process. This switch has fast response speed and can be operated frequently.
