Load characteristics
.
Telecommunications equipment in the communications equipment, data room equipment, dedicated room air conditioning equipment on the power supply continuity requirements are very high, very sensitive to voltage fluctuations, a variety of electromagnetic interference will affect the data exchange equipment.
There are large-capacity harmonic source loads in telecom buildings, most of which are single-phase nonlinear loads, including:
◆ UPS power supply, stand-alone capacity, most of the 6-pulse UPS uninterruptible power supply equipment (3,5,7 times, etc.)
◆ switching power supply, mainly used for computer and other office equipment, power supply, the number of (3,5,7 times, etc.)
◆ inverter air conditioner, elevator, water pump, a large number of use, variable frequency drive equipment as the main harmonic source (5,7 times, etc.)
.
solution
.
For all low voltage systems, configure the low voltage dynamic reactive power compensation device to absorb the main harmonic components in the system; in the heavily polluted low voltage system, configure the parallel active power filter device; in the key load, configure the intelligent hybrid filter compensation device to To achieve the best governance effect.
