Product Description
XBZ1 Intelligent 12 kV (10 kV) Box-type Substation
——From "Box Substation" to "Cloud" Distribution Network Intelligent Terminal
I. Product Overview
XBZ1 is an "intelligent + environmentally friendly" integrated prefabricated substation jointly developed by Tianjin Electric Drive Design Research Institute and more than 100 backbone enterprises nationwide. It integrates 12 kV (10 kV) switches, transformers, 0.4 kV low voltage, reactive power compensation, and intelligent monitoring units into a weather-resistant enclosure, truly achieving "networking upon arrival and intelligent operation upon power-on."
II. Core Technical Parameters
| Item | Typical Value |
| Rated Voltage | High voltage 12 kV (maximum operating voltage 12 kV); Low voltage 0.4 kV |
| Rated Capacity | 50 – 1600 kVA (oil transformer S11-M or dry transformer SCB) |
| High Voltage Switch | SF6 ring main unit / vacuum load switch-fuse combination, 630 A, 20 kA/4 s |
| Low Voltage Switch | Intelligent molded case circuit breaker 100 – 2500 A, Icu 30 – 65 kA |
| Short-time withstand | High voltage 20 kA/2 s; Low voltage 30 kA/1 s |
| Insulation Level | Power frequency 42 kV/1 min; Lightning impulse 75 kV |
| Noise | Oil transformer < 50 dB; Dry transformer ≤ 55 dB |
| Protection Level | Enclosure IP54-D; Internal high-voltage compartment IP67 |
| Operating Environment | -45 ℃ ~ +45 ℃, Altitude ≤ 2000 m, Earthquake resistance 8 degrees |
III. Intelligent System Configuration
1. "Four Remote" functions: Remote measurement, remote signaling, remote control, and remote adjustment are all standard, supporting GPRS/4G/fiber + IEC 61850/Modbus-TCP dual-protocol cloud access.
2. Fault self-healing: When multiple box substations operate in a "hand-in-hand" ring network, fault location, isolation, and load transfer can be completed within 1 min.
3. AI early warning: Integrates surge arrester operation counting, fuse life curve algorithm, and online monitoring of transformer top oil temperature and local placement, and proactively pushes abnormal information 7×24 h in advance.
4. Mobile phone/WEB maintenance: Real-time power, switch position, access control, smoke, water immersion, and temperature and humidity are clear at a glance, supporting remote switching and parameter setting.
IV. Structural Highlights
• Footprint < 6 m², saving 80% land compared to traditional civil construction stations; can be hoisted as a whole, and commissioning can be completed within 4 hours on site.
• Double-layer color steel (optional stainless steel or GRC non-metal) + labyrinth air duct, corrosion-resistant, anti-condensation, anti-salt spray, lifespan ≥ 25 years.
• Modular busbar plug-in design, expansion or maintenance does not require power outage, unit replacement can be completed in 30 min.
V. Typical Application Scenarios
• Urban distribution network area capacity expansion, old community renovation
• Industrial and commercial rooftop photovoltaic, distributed wind power 12 kV step-up grid connection
• Data centers, hospitals, subways, airports and other Class A load power supply
• Oil fields, mines, ports, highways and temporary construction power supply
VI. Implementation Standards
GB/T 17467-2021, IEC 62271-202, DL/T 537-2018, with national-level full-type test (TTA) report and 3C certification.
Choosing XBZ1 means choosing a "thinking, self-healing, and remote" 12 kV intelligent box substation.
