The XBJ24 Type Two Station Electric Operating Mechanism is a motor-driven operating device developed for modern gas insulated switchgear (GIS), SF6 fully enclosed composite electrical equipment, disconnect switches, and grounding switches. Designed to provide dependable switching performance in high-voltage substations and power transmission systems, the mechanism combines advanced transmission technology, precision positioning, and comprehensive safety interlocking functions.

Suitable for voltage classes of 72.5kV, 126kV, and 252kV, the XBJ24 mechanism offers an efficient solution for utilities, EPC contractors, switchgear manufacturers, and industrial power projects that require reliable switch operation and long-term service stability.

Through its intelligent mechanical design and robust enclosure construction, the mechanism delivers accurate opening and closing operations while maintaining excellent protection against environmental challenges.

Engineered for GIS and SF6 Switchgear Applications

As modern substations increasingly adopt GIS technology to improve space utilization and operational reliability, the demand for dependable operating mechanisms continues to grow.

The XBJ24 mechanism is specifically designed for:

• SF6 fully enclosed switchgear

• GIS substations

• Disconnect switches

• Grounding switches

• Power transmission systems

• Utility substations

• Renewable energy facilities

• Industrial electrical networks

• Railway power infrastructure

The mechanism can also operate other switch types with compatible load and rotational angle requirements.

Advanced Motor-Driven Transmission System

The XBJ24 utilizes a highly reliable electric motor and worm gear transmission structure. During operation, the motor rotates in forward or reverse directions according to the switching command.

After the switch reaches its designated position, the clutch system automatically disengages, protecting the transmission components from excessive stress and ensuring precise switch positioning.

This design offers several operational advantages:

• Stable torque transmission

• Smooth switching action

• Reduced mechanical wear

• Accurate switch positioning

• Improved service life

• Reliable operation under heavy-duty conditions

The automatic clutch mechanism significantly enhances long-term operational reliability while minimizing maintenance requirements.

Dual Manual and Electric Operation Capability

To ensure maximum operational flexibility, the XBJ24 provides both electric and manual operating modes.

Under normal conditions, switching operations are performed electrically through remote or local control systems. During maintenance activities or emergency situations, operators can safely use manual operation functions.

This dual-mode capability provides:

• Enhanced operational flexibility

• Emergency backup operation

• Improved maintenance convenience

• Reduced downtime risk

• Increased system availability

Such functionality is particularly valuable for utility substations and critical infrastructure projects where uninterrupted operational capability is essential.

Comprehensive Five-Prevention Interlocking System

One of the most important features of the XBJ24 is its complete five-prevention interlocking system.

The mechanism incorporates:

• Electrical and manual operation interlocking

• Electromagnetic locking of electrical components

• Handle insertion and removal interlocking

• Padlock security capability

• Electrical locking during maintenance

These safety functions work together to prevent operational errors and unauthorized switching actions.

The result is improved personnel safety, enhanced equipment protection, and compliance with modern substation safety requirements.

High-Visibility Position Indication

The mechanism features a unique three-sided indication system.

Within a 120-degree viewing range, operators can clearly determine:

• Switch open position

• Switch closed position

• Operational status

• Maintenance status

This visual indication system improves operational efficiency while reducing the likelihood of misinterpretation during field inspections and maintenance activities.

Environmental Protection and Reliability

Substation equipment often operates in harsh environmental conditions including dust, humidity, rain, and temperature fluctuations.

To address these challenges, the XBJ24 is equipped with:

• Temperature controller

• Humidity controller

• Electric heating plate

• Ventilation window

• Dustproof enclosure

• Waterproof sealing system

The enclosure achieves IP55 protection, ensuring reliable performance in outdoor and industrial environments.

These features are particularly beneficial for projects in Europe, the Middle East, Africa, and coastal regions where environmental protection is critical.

Compact Design with High Precision

Despite its powerful performance capabilities, the XBJ24 maintains a compact enclosure size of only 364 × 359 × 132 mm.

The slim-profile design offers:

• Easy installation

• Reduced cabinet space requirements

• Simplified integration into GIS systems

• Lower transportation costs

• Improved equipment layout flexibility

Positioning accuracy is controlled within ±1°, ensuring highly precise switch operation.
