The filter compensation device adopts the change of reactive power load of the microcomputer system to automatically judge the switching and optimize the input of filter branch, so as to maintain the power factor of the system in the best state. The main circuit adopts the method of thyristor group valve switching filter compensation branch. The filter compensation branch is composed of professionally designed and manufactured filter reactors, filter capacitors, and filter resistors. Filter compensation is performed on-site to eliminate harmonics of specific frequencies and compensate for no harmonics. power and improve power factor.
Application fields
Main Features
Adopt microcomputer operating system kernel, with strong anti-interference ability, accurate and fast calculation, and develop strategies according to the system conditions.
When the device is put into operation, the power factor of the received power increases to above, which reduces the line loss of the distribution and increases the load-bearing efficiency of the distribution transformer.
, adopts contactless automatic switching of each filter branch, with fast response speed, and can continuously and frequently switch filter branches safely and reliably.
, Quickly detect system conditions, and compensate reactive power in real time according to system changes (reactive power conditions, power factor).
, No transient impact during switching, no closing inrush impact, no arc re-ignition, no need Discharge and re-invest.
, Complete protection functions, including short-circuit protection, over-voltage protection, over-current protection, thyristor overheating protection, etc., with high operational reliability.
, Improve the current impact caused by impact loads, Reduce voltage fluctuations, improve voltage stability, and improve voltage quality.
, Automatically exit work when external faults or power outages occur, and automatically resume operation after power is supplied.
, Multiple filter compensation forms, three-phase total compensation Filtering, three-phase split-complement filtering, total complement plus split-complement filtering.
, advanced equipment technology, accurate tuning, high reliability, low maintenance, and durability.
