Why Choose ZHIMING's Reactive Power Compensation and Metering Distribution Cabinet?
Integrated Compensation & Metering
ZHIMING's reactive power compensation and metering distribution cabinet combines reactive power compensation and precise metering in one unit, eliminating separate enclosures and reducing installation space by up to 35%.
High Breaking Capacity & Thermal Stability
Equipped with high-performance circuit breakers and switching capacitors, the cabinet ensures reliable short-circuit protection and excellent thermal dissipation, even under heavy load conditions.
Auto & Manual Compensation Modes
The intelligent controller automatically switches capacitor banks based on real-time power factor (0.9–1.0 adjustable), with manual override for maintenance or special grid conditions.
IP33 High Protection Degree
With robust structural design, ZHIMING's reactive power compensation and metering distribution cabinet achieves IP33 rating – dust-tight and rainproof, ideal for outdoor pole-mounted or ground installations in urban/suburban networks.
Compliant with GB/T15576 & JB/DQ6141-86
Fully certified to Chinese national standards for low-voltage reactive power static compensation devices, ensuring safety, reliability, and long service life (≥15 years).
PERTANYAAN YANG SERING DIAJUKAN
What is the rated voltage and current range of this cabinet?
Standard model is rated at AC 400V, 50Hz, with maximum rated current 600A. Customization up to 800A is available upon request.
How is the reactive power compensation controlled?
It uses an automatic power factor controller with thyristor or contactor switching. The target power factor can be set between 0.85 and 1.0, with response time ≤ 20ms for thyristor type.
Does the reactive power compensation and metering distribution cabinet include metering components?
Yes. It comes with built-in current transformers (CTs) and space for a smart meter (or mechanical meter). Both active and reactive energy metering are supported.
Can it be used in harsh outdoor environments?
Absolutely. With IP33 protection, galvanized steel enclosure, and anti-corrosion coating, it withstands rain, dust, and temperature variations from -25°C to +40°C.
What protection functions are included?
Overload, short-circuit, over-voltage, under-voltage, and phase-loss protection. Optional surge protection device (SPD) can be added for lightning-prone areas.
