Auxiliary Equipment
- Fault Indicator: The DJD-1 short-circuit grounding fault indicator uses logic circuits for over-current alerts and manual reset, with sensors on cables and a display unit for quick fault detection.
- Condensation Controller: This device monitors temperature/humidity in real-time, activating heaters at 85%RH to prevent condensation (rated power: 75–100W).
- FTU & Communication: The DAT-1L automation terminal enables SCADA integration with 48 remote signaling channels, self-diagnosis, and multi-protocol support (IEC101, MODBUS, etc.).
- Current Limiting Fuse: Designed for 24kV/50Hz systems (292mm length), it protects indoor switchgear from overcurrent faults.
Frequently Asked Questions
What is the rated voltage of the XGN15-24 Medium Voltage Switchgear?
The XGN15-24 is rated at 12kV with a rated frequency of 50Hz. It is designed for indoor, fixed-type, box-construction installations in medium voltage distribution systems.
What types of load switches are compatible with the XGN15-24?
The XGN15-24 supports two load switch types: Type I uses the FLN36-12 Load Switch, and Type II uses the FLN48-12 Load Switch, offering flexibility for different application requirements.
What are the environmental requirements for installing the XGN15-24 switchgear?
The switchgear should be installed at altitudes no greater than 2000m, with ambient temperatures between −25°C and +40°C. Daily humidity must not exceed 95% and monthly average humidity must not exceed 90%. The seismic capacity is Grade 8, and the environment must be free of explosive/corrosive gases and severe vibration.
What is the protection class and mechanical endurance of the XGN15-24?
The XGN15-24 carries a protection class of IP3X to protect against solid particle ingress. Its mechanical endurance is rated at 2,000 operations, ensuring long-term reliability in demanding power distribution environments.
Does the XGN15-24 support SCADA or remote monitoring integration?
Yes. The optional DAT-1L FTU (Feeder Terminal Unit) enables full SCADA system integration with 48 remote signaling channels, built-in self-diagnosis, and support for multiple communication protocols including IEC101 and MODBUS.
What auxiliary protection devices are available for the XGN15-24 switchgear?
Key auxiliary equipment includes the DJD-1 Fault Indicator for over-current detection, a Condensation Controller that activates heaters at 85%RH to prevent moisture damage, and a Current Limiting Fuse designed for 24kV/50Hz systems (292mm length) to protect against overcurrent faults.
