6kV–132kV Vehicle-Mounted Mobile Substation
Vehicle-mounted mobile substations are primarily designed to serve as replacements for conventional substations during emergencies, to alleviate power supply shortages during peak load seasons, and to function as temporary substations. They offer the capability to rapidly replace a conventional substation and restore power supply; once the substation arrives on-site, it can be put into operation simply by connecting the input and output cables. Mobile substations boast a range of outstanding advantages, including a simple and compact structure, ease of mobility, reliable functionality, simple and rapid operation, straightforward maintenance, and a high degree of intelligence. Pre-fabricated, semi-trailer-mounted mobile substations can be custom-designed to meet specific user requirements and operating conditions, configured as a single-vehicle unit or as a multi-vehicle assembly.

Functions and Features:
1. Possesses all the functions of a conventional substation:
Including functions such as control, protection, lightning protection, and voltage reduction.
Electrical energy can be distributed to several branch circuit users.
2. Easy installation and rapid commissioning;
3. Simply connect the cables, and the equipment is ready for operation;
4. Implement vibration-isolation measures, including shock absorption, temporary support rods, and flexible connections for circuit components.
Structural composition:
1.It is divided into a high-voltage section, a main transformer, and a low-voltage switchgear room.
2.The high-voltage switchgear employs either a combined electrical apparatus or open-type disconnect switches and magnetic-pole circuit breakers as the main switch, and is mounted on a semi-trailer.
3.The low-voltage switchgear room houses low-voltage switchgear, control power supplies, DC panels, and control, protection, and metering equipment.
Characteristics of low-voltage indoor switchgear:
1. Adopts a three-layer insulated shell:
2. Equipped with air conditioning, which can be turned on as needed:
3. The substation enclosure has a maximum protection rating of IP43; the storage batteries for the DC power supply in the low-voltage switchgear room are of a fully sealed type.
