Low Noise Eco-Friendly 10kV Prefabricated Substation for Residential Use - China Suppliers and Factory Solutions
Multiple Safety Guarantees and Convenient Maintenance Features
1
Multi-layer Physical Protection System: The box body adopts anti-theft design, and the door lock has anti-picking function. Mechanical interlock or electrical interlock is set in the high-voltage room and the low-voltage room respectively, strictly preventing accidental entry into the energized compartments. The transformer room is equipped with an independent pressure relief channel, which can quickly release pressure in case of a fault, ensuring the safety of personnel and equipment.
2
Intelligent Monitoring and Early Warning: An optional intelligent monitoring system can be equipped. It can monitor parameters such as transformer temperature, load rate, key node temperature, access status, and environmental temperature and humidity in real time. The data is transmitted wirelessly to the monitoring center, enabling remote operation and fault early warning, transforming "scheduled maintenance" into "condition-based maintenance".
3
Humanized Maintenance Design: Each functional room is equipped with an independent maintenance door, and the width of the maintenance passage complies with safety standards. The high-voltage cable heads are designed with a touchable feature, allowing for safe operation without the need for special tools during maintenance. The main components are all designed with front maintenance features, enabling all maintenance operations to be completed from the front.
4
Quick Relocation and Reuse: The bottom of the box is equipped with standard lifting holes and transportation fixation points, allowing for overall handling using general lifting equipment. During relocation, only the incoming and outgoing cable connections need to be disconnected, significantly enhancing the equipment's utilization rate and return on investment. It is particularly suitable for the rental market and temporary power supply scenarios.
