Mining electrical equipment must operate reliably under demanding underground conditions. For manufacturers, mining maintenance workshops, and equipment management departments, comprehensive testing of explosion-proof electrical equipment is essential to verify electrical safety, protection performance, and withstand capability before equipment is put into operation.

To meet these testing requirements, Sansion Power developed the SXGK-F Explosion-Proof Electrical Equipment Comprehensive Test Bench, an integrated testing solution designed specifically for mining electrical equipment inspection.

The system combines multiple electrical testing functions into one platform, helping customers perform voltage, high-current, leakage protection, power frequency withstand voltage, and other tests with improved efficiency and standardized procedures.

Traditional testing methods may require several independent test devices and repeated wiring operations for different test items. This can increase testing time, complicate operation, and make test data management more difficult.

For mining electrical equipment manufacturers and maintenance teams, a more integrated solution is needed to:

• Test different rated voltage levels on one platform
• Perform high-current overload and short-circuit protection tests
• Verify leakage protection and leakage locking performance
• Conduct power frequency withstand voltage tests
• Automatically record test data and generate reports
• Improve testing efficiency while maintaining operational safety

The SXGK-F was designed to address these requirements with a centralized, multi-function testing platform.

The SXGK-F Explosion-Proof Electrical Equipment Comprehensive Test Bench consists mainly of a centralized control console and current cabinet.

With a rated input capacity of 120 kVA, the system integrates multiple testing modules and supports both manual control and PLC automatic control. An industrial computer can automatically collect test data, generate test reports, and support cloud-based data uploading.

The system is designed according to relevant standards including GB 14048 and GB/T 11022, providing a practical solution for mining electrical equipment testing.

The SXGK-F provides multiple selectable test voltage levels, including:

• 127 V
• 660 V
• 1140 V
• 3300 V

The output voltage can be continuously adjusted from 0 to 120% of the rated voltage, allowing engineers to perform different voltage-related tests according to the requirements of the test object.

For overload and short-circuit protection testing, the system can provide an instantaneous current of up to 10,000 A on Phase A, enabling high-current testing of protection characteristics.

Leakage protection is an important part of mining electrical safety.

The SXGK-F integrates a complete leakage testing module with an adjustable leakage resistance range of 0–199.9 kΩ. It can also provide zero-sequence voltage and current outputs for different leakage protection tests.

The system can be used to evaluate:

• Leakage locking performance
• Leakage protection operating time
• Leakage compensation rate
• Zero-sequence voltage and current characteristics

With timing accuracy down to 1 ms, the system helps engineers accurately evaluate protection response characteristics.

The integrated 0–10 kV power frequency withstand voltage test unit allows users to perform insulation withstand tests on applicable mining electrical equipment.

If breakdown occurs during testing, the system can automatically cut off the test power and trigger an alarm, providing additional protection for both the test equipment and operators.

Testing efficiency is not only determined by electrical performance. Test data management is also important for manufacturers and maintenance departments.

The SXGK-F can automatically collect test parameters and generate test records through the industrial computer. Test reports can be generated and printed after testing, while test data can also be uploaded to the cloud according to the customer's data management requirements.

This helps reduce manual recording work and provides more consistent test documentation.

The SXGK-F is suitable for comprehensive testing of various mining electrical products, including:

• High-voltage vacuum power distribution equipment
• High- and low-voltage feeder switches
• Electromagnetic starters
• Coal drill electrical equipment
• Lighting and signaling comprehensive protection devices
• Mining explosion-proof switches
• Other applicable mining electrical protection equipment

It can be used in explosion-proof electrical equipment manufacturing plants, coal mine electrical maintenance workshops, and mining equipment management departments for factory inspection, maintenance testing, acceptance testing, and routine performance verification.

For mining electrical equipment manufacturers and service teams, integrating multiple test functions into one test bench can simplify the testing workflow.

Instead of using separate equipment for different electrical tests, the SXGK-F provides a centralized platform for high-current testing, leakage protection testing, voltage testing, and power frequency withstand voltage testing.

Combined with PLC control, automatic data acquisition, and report generation, the system helps create a more standardized testing process.

With the SXGK-F, customers can establish a centralized testing platform for mining explosion-proof electrical equipment and perform multiple inspection procedures through one integrated system.

The solution helps improve:

Testing Efficiency — Multiple test functions are integrated into one platform.

Testing Accuracy — Digital measurement, high-current output, and millisecond-level timing support precise performance evaluation.

Operational Safety — Automatic protection, breakdown power-off, and alarm functions improve test safety.

Data Management — Automatic data acquisition and report generation simplify test documentation.

Testing Flexibility — Multiple voltage levels and adjustable test parameters accommodate different mining electrical equipment.

As mining electrical equipment becomes increasingly important to underground operational safety, reliable electrical testing is essential before equipment enters service.

The SXGK-F Explosion-Proof Electrical Equipment Comprehensive Test Bench provides an integrated solution for mining electrical equipment testing, combining high-current testing, leakage protection testing, voltage testing, power frequency withstand testing, automatic data acquisition, and test report generation in one system.

For manufacturers and mining maintenance teams looking to improve mining electrical equipment inspection, explosion-proof electrical testing, and electrical safety verification, the SXGK-F offers a practical one-stop testing platform.
