Power capacitor structure characteristics
Datetime: 2017-06-06 Visit: 4514
Modular structure
The intelligent power capacitor has a modular structure, small size, simple field wiring and convenient maintenance. The expansion of the reactive power compensation system can be realized only by increasing the number of modules.
High quality capacitor
The self-healing low-voltage compensation capacitor is used, and the capacitor has a built-in temperature sensor, which reflects the internal heating degree of the capacitor and realizes over-temperature protection.
Embedded switching switch module
The smart power capacitor has a built-in switching switch module. The switching switch module is composed of a thyristor, a magnetic holding relay, a zero-crossing triggering conducting circuit and a thyristor protection circuit, and realizes a "zero switching" of the capacitor, ensuring no surge current impact during the switching process, and no operation overvoltage. The switch module responds quickly and can operate frequently.
Perfect protection design
Intelligent power capacitors have functions such as power failure protection, short circuit protection, voltage phase loss protection, and capacitor over temperature protection to effectively protect capacitors and extend equipment life.
Advanced control technology
The control physical quantity is reactive power, and the reactive power flow prediction and delay multi-point sampling technology are adopted to ensure that the switching has no oscillation. When reloading, reactive power is fully compensated.
Anti-switching oscillation technology
The unique design principle is adopted to prevent the controller from crashing and uncompensating or overcompensating the scene to prevent the capacitor from switching.
Automatic compensation of reactive power
The intelligent power capacitor automatically switches according to the magnitude of the reactive power of the load, dynamically compensates the reactive power, and improves the power quality. Smart capacitors can be used in a single unit or in multiple units.
Human-machine interface friendly
Display equipment operating parameters such as current, voltage, and reactive power.
The switching status, the composite switch module fault status, and the communication status are displayed.
It can also easily realize debugging/working status switching and manual/automatic operation functions.
constitute
The intelligent power capacitors are modular in design and the components are:
High quality capacitor
Intelligent measurement and control module
Switching switch module
Line protection module
Human machine interface module
Smart power capacitors can be used in a single unit or in multiple units. It replaces the conventional automatic reactive power compensation device composed of intelligent controllers, fuses, composite switches or mechanical contactors, thermal relays, low-voltage power capacitors, indicator lights, etc., which are connected by wires.
Intelligent power capacitor integrated intelligent control module, fast switching switch and capacitor protection, compact design, flexible configuration to meet user demand for reactive power compensation
