Guangxi Agricultural Engineering Vocational and Technical College Phase II Power Distribution Project
The training complex building of Guangxi Agricultural Vocational and Technical University needs to provide power support for scenarios such as agricultural machinery training, intelligent greenhouses, and precision instruments, with strict requirements for power supply continuity, safety protection, and space efficiency. This project uses Box-type substation+ 10kV outdoor switchgear + KYN28-12 switchgear combination scheme to meet the intensive power distribution needs of the campus.

Customer Value
1. Box-type substation
− Trinity integration: high voltage cabinet, transformer, low voltage cabinet overall packaging (compliant withGB/T 17467 standard), reducing the equipment footprint.
− Environmental adaptability: stainless steel/Aluminum alloy double-layer box (IP54 protection grade), resistant to high temperature and high humidity climate.
− Intelligent expansion: optionalThe FTU terminal supports the "four remote" functions and seamlessly connects to the campus energy management system.
Space intensification:The outdoor deployment of box-type substations eliminates the need for the construction of independent power distribution rooms.
Essential safety improvement:
− The touchable cable heads in the switchgear eliminate the risk of electric shock;
− The five-prevention interlocking of the KYN28 cabinet body prevents misoperation.
Optimization of operation and maintenance efficiency:
− Remote monitoring of the box - transformer status reduces on - site inspections;
− The handcart structure of the switchgear shortens the equipment maintenance time.
Sustainable expansion:The multi - circuit design of the switchgear station reserves the capacity for load expansion.
2. 10kV Outdoor Switchgear (Cable Branch Box)
− Flexible branching capability: Support8-circuit outgoing lines for independent power distribution to different functional areas (such as processing workshops and laboratories).
− Full insulation protection: Pre - fabricated touchable silicone rubber cable heads (with inner and outer semiconductor shielding layer design) to achieve direct contact protection for personnel.
− Convenient maintenance: Zoned isolation design to minimize the power outage range.
3. KYN28-12 Armored withdrawable switchgear
− High-reliability structure: Vacuum circuit breaker (VS1 series) meets the requirements of frequent operations (complies with GB3906 standard).
− Five-prevention interlocking mechanism: Mechanical and electrical interlocks to forcibly prevent misoperation.
− Modular maintenance: The handcart design supports rapid equipment replacement.
1. Space constraints
The campus land is in short supply. The construction of traditional power distribution rooms has high costs and long cycles.
2.Safety risk
There is a risk of electric shock when non - professionals come into contact with high - voltage equipment.
3.Operation and maintenance burden
Frequent start - stop of training equipment can easily exacerbate electrical losses, and the maintenance complexity is high.
4.Expanded requirements
Power expansion interfaces should be reserved for future new laboratories.
