Applications:

This high-voltage switch comprehensive testing equipment can be widely used in the following typical scenarios:

1. Substation operation and maintenance
Conduct preventive tests or fault diagnosis on SF6 circuit breakers, vacuum switches, GIS, etc. in operation, quickly evaluate mechanical performance and contact status of contacts, and ensure the safety of the power grid.

2. Manufacturing and factory testing of high-voltage switches
In the production line or quality inspection process, full parameter testing is conducted on various types of circuit breakers (including graphite contacts, special structures with closing resistors, etc.) to ensure that the products comply with national standards and industry specifications.

3. Installation and commissioning of power engineering
In the construction or renovation of substation projects, perform functional verification on newly installed high-voltage switchgear before commissioning, including low voltage operation tests, synchronization tests, etc.

4. Electric power research and third-party testing institutions
Used for type testing, technical research, or certification testing, supporting high-precision data acquisition, waveform analysis, and report generation to meet the needs of professional laboratories.

5. Power distribution systems for large industrial and mining enterprises and self owned power plants
Regularly inspect internal high-voltage distribution equipment to promptly detect potential hazards such as contact wear, mechanism jamming, and abnormal circuit resistance, in order to avoid sudden power outages.

Profile:

This product is a comprehensive testing system for high-voltage switches, integrating mechanical characteristic testing and three-phase 100A main circuit contact resistance measurement functions, designed specifically for the power system and switchgear industry.

It can perform full function and high-precision testing on various high-voltage circuit breakers, including SF6 switches, vacuum switches, oil switches, GIS combination devices, as well as special structure switches such as double ended grounding, graphite contacts, and closing resistors. One opening and closing operation can automatically obtain:
Opening/closing time, synchronicity, bounce frequency and waveform
Just open/close speed, maximum speed, stroke, overtravel, rebound amplitude
Current waveform and operating voltage of the opening and closing coil
Three phase main contact contact resistance (100A constant current output)

The device is controlled by a tablet computer and has a Chinese menu interface, making it easy to operate; The built-in printer can quickly output data and graphs on site; Support PC online analysis and generate standardized test reports. It has strong anti-interference ability and can accurately measure even near 500kV live substations.

Suitable for scenarios such as substation maintenance, switch manufacturing factory quality inspection, power engineering commissioning, scientific research institutions, and large industrial and mining enterprises, it is currently a comprehensive and cost-effective intelligent testing solution for high-voltage switches on the market.
