Overall load changes smoothly, need to inhibit harmonic compensation reactive power, improve the power factor of the user to install harmonic cabinet. For example: metal smelting plant, rolling mill (cold rolling), plastic products factory, metal products factory, electroplating plant, pipe factory, chemical factory, saw blade factory, heat treatment plant, cement factory, paper factory, water supply plant, salt chemical plant, ceramic factory, plate and strip processing plant.
The harmonic cabinet adopts the microcomputer dynamic filter compensation controller with 80C196 microcontroller as the core, and the main circuit adopts the control mode of high-performance contactor casting and cutting filter compensation branch, which automatically casts and cuts according to the user's systematic reactive power, power factor, harmonics and other comprehensive judgments. The filtering branch circuit consists of professionally designed and manufactured filtering reactor, filtering capacitor and filtering resistor, which can carry out filtering compensation in situ, inhibit the harmonics of specific frequency, compensate the reactive power and improve the power factor.
Filter compensation equipment is highly reliable, low maintenance and durable. It can automatically withdraw from work during external failure or power outage, and resume operation automatically after power supply, without human intervention.
Expanded Information
Features:
1, designed and manufactured for the user's power system reactive power, harmonics, suppressing high harmonics while compensating reactive power.
2, the filter compensation device into the receiving power factor increased to more than 0.95, harmonics are suppressed, so that the distribution network line loss reduction, distribution transformer carrying efficiency increased.
3, the use of high-performance contactors and integrated protection and control system to cut the filtering compensation branch, so that the equipment operation is simple, safe and reliable.
4, fast detection of power system conditions, according to system changes (reactive power, power factor) automatic switching, real-time provision of the required reactive power.
5, complete protection functions, with short-circuit protection, over-voltage protection, over-current protection, etc., high operational reliability.
6. It improves the current shock caused by impact load, reduces voltage fluctuation and suppresses voltage flicker, improves voltage stability, and improves voltage quality.
7, in the external fault or power outage automatically exit the work, power supply automatically resume operation.
8, advanced equipment technology, high reliability, low maintenance, durable.
