Structure
Key components of the 1000 kVA compact substation provide waterproofing, dustproofing and corrosion resistance for harsh environments.
- Transformer Compartment: The core unit for voltage step-up/step-down conversion.
- Switchgear Compartment: Includes incoming switches, load break switches, disconnectors and combined switches.
- Cable Tunnel: Used for cable maintenance.
- Cabinet Compartment: Ensures proper air conditioning for the substation and serves as a passage for metering, dispatching and monitoring devices.
Auxiliary devices, such as distribution panels and cabinet-type racks, offer circuit protection, control, display and communication functions for the power distribution system.
Control devices include various control panels for operating and monitoring the substation’s functions.
Safety Protection Measures
Explosion & Fire Prevention
For environments with explosive gases or fire risks, necessary explosion-proof and fire-resistant measures should be implemented inside the substation, such as using flame-retardant materials.
Five Protection Interlocking Mechanism
1.Prevent accidental opening/closing of circuit breakers
2.Prevent load-breaking disconnect switch operations
3.Prevent live grounding wire installation
4.Prevent energizing with grounding wires connected
5.Prevent unauthorized access to live compartments
Dehumidification
In humid environments, dehumidification devices should be installed inside the enclosure to prevent condensation, thereby protecting electrical components from damage.
Operation
Daily Inspection
1.Check the substation’s exterior for damage
2.Ensure door locks are intact
3.Verify that ventilation openings are not blocked
Electrical Testing
Conduct preventive tests on the electrical equipment inside the substation at scheduled intervals to ensure they are in good condition.
Regular Maintenance
1.Properly maintain key components
2.Replace aged or damaged parts in time
Fault Handling
1.Respond promptly with corrective measures to restore power supply
2.Document fault details for further analysis and improvement
