The intelligent box-type substation is an integrated distribution equipment that integrates high-voltage distribution, transformer reduction, low-voltage output, safety protection, data collection, intelligent control, remote interaction, etc., based on the traditional pre-assembled box-type transformer. It combines modern sensing monitoring, Internet of Things communication, edge computing, intelligent protection and remote operation technologies. It is a core complete set of equipment for the intelligent transformation of new distribution networks, power supply for industrial parks, power supply for new energy, power supply for municipal and industrial commercial areas, and other applications.
The product adopts a modular compartment-sealed structure, strictly dividing the high-voltage room, transformer room, low-voltage room and intelligent measurement and control terminal compartment. The entire box has high-strength anti-corrosion, dust-proof, waterproof, high-low temperature resistance, and anti-condensation performance, and can operate stably outdoors in complex conditions for a long time. The internal integrates an integrated distribution unit, including high-voltage switches, power transformers, low-voltage distribution cabinets, metering devices, reactive power compensation, lightning protection and grounding, etc., and also carries high-precision voltage and current sensors, temperature and humidity sensors, partial discharge monitoring components, oil temperature and oil level monitoring, door control security probes, etc., to achieve real-time collection of equipment operation status.
The system is equipped with dedicated intelligent distribution terminals and edge gateways, integrating relay protection, fault alarm, fault location, automatic reclosing, harmonic monitoring, and power quality analysis functions. It can accurately cut off and handle faults such as overload, short circuit, leakage, and overheating within milliseconds. It supports on-site touch screen human-machine interaction and can also upload operation data, alarm information, curve reports, etc., in real time to the distribution cloud platform and the central control center through 4G/5G, Ethernet, optical fiber, etc. communication methods, achieving remote telemetry, remote signaling, remote control, and remote regulation four remote control functions.
Based on the built-in intelligent algorithms, the equipment can achieve intelligent load optimization, peak-valley load linkage, reactive power dynamic compensation, improvement of power supply reliability, and can also be compatible with and connect distributed energy units such as photovoltaic, energy storage, charging piles, etc., and adapt to the demand for micro-grid coordinated operation. The entire machine is factory-preformed integrated and factory-ready for complete debugging and verification. On-site, only positioning and fixing are required, and connecting cables can be connected quickly for rapid operation, significantly shortening the construction period and reducing on-site installation and wiring errors.
Compared with traditional ordinary box-type transformers, the intelligent box-type substation has the advantages of visible operation, fault determination, controllable status, and remote controlable operation. It significantly reduces the frequency of manual inspection and realizes condition-based maintenance instead of traditional regular maintenance, effectively reducing the full life cycle operation costs and improving the safety, stability and automation level of the distribution network power supply.
This product is widely used in the upgrading of old urban distribution networks, residential areas, industrial parks, municipal roads, transportation hubs, industrial and mining enterprises, photovoltaic and wind power power supply, and charging pile cluster power supply scenarios, and is compatible with the current development direction of intelligent, digital and unmanned operation of the new power system.
