Communication
Program description
Load analysis: Communication equipment, data room equipment, and special room air-conditioning equipment in telecommunications buildings have very high requirements for power supply continuity and are very sensitive to voltage fluctuations. Various electromagnetic interference will affect data exchange equipment. There are large-capacity harmonic source loads in telecommunications buildings, most of which are single-phase nonlinear loads, including:
UPS power supply, single unit has large capacity, most of which are 6-pulse UPS uninterruptible power supply equipment (3, 5, 7 times, etc.);
Switching power supply, mainly used for power supply of office equipment such as computers, in large quantities (3, 5, 7 times, etc.);
Frequency conversion air conditioners, elevators, water pumps, etc. are used in large quantities, and frequency conversion drive equipment is the main harmonic source (5th, 7th, etc.).
Recommended solution: anti-harmonic low-voltage intelligent power capacitor + active filter (APF). More
Recommended plan

Recommended solution: anti-harmonic low-voltage intelligent power capacitor + active filter (APF).

Use anti-harmonic low-voltage intelligent power capacitors to improve power factor.

Since there are a large number of third harmonics in the system, it is recommended to select 14% for the reactive power compensation reactance coefficient, which is that the safety compensation circuit is capacitive at the fundamental frequency and compensates for the fundamental reactive power, and at the harmonic frequencies above the third It is inductive, effectively suppressing the 3rd harmonic resonance and protecting the capacitor.

Active filters filter on-site. In-situ filtering is an effective filtering method of active filters, which can effectively control harmonics; each active filter compensates the harmonics generated by multiple UPSs and switching power supplies on-site to avoid the interference of harmonics on important equipment and improve System capacity and use efficiency improve the reliability of the system.
