In the field of power equipment testing, Wuhan Longdian Electric has launched a high-voltage switch characteristic and loop resistance test system based on years of technical accumulation and innovation. With highly customized services as the core, it provides accurate and efficient solutions for customers such as circuit breaker manufacturers, State Grid, and third-party testing agencies, helping power equipment to operate safely and stably.

Core product advantages: customized design, precise adaptation

Fully compatible testing capabilities

Supports all types of SF6 switches, vacuum switches, oil switches and GIS combination electrical appliances at home and abroad, covering various types such as low oil, high oil, and permanent magnet.

Equipped with linear, rotary, acceleration sensors and multi-functional brackets, it can flexibly adapt to the installation scenarios of different circuit breakers, such as sealed VS1, outdoor ZW32 and other complex structures.

Intelligent operation experience

Equipped with industrial-grade computers, 15-inch touch screens and Windows 10 systems, the interface is intuitive and supports switching between Chinese and English, greatly improving on-site operation efficiency.

One-click acquisition of 12-way break data, real-time display of closing and opening time, number of bounces, coil current and other parameters, synchronous generation of waveforms to meet dynamic analysis needs.

High precision and safety

Time measurement accuracy reaches ±0.05%+0.1ms, and speed measurement error is only ±0.1m/s, ensuring data reliability.

Built-in multiple protection mechanisms: anti-short circuit design, automatic power cut-off function, to ensure the safety of equipment and personnel.

Customized service highlights: flexible response to customer needs

Free configuration of power supply and trigger mode

Provides DC6~270V adjustable power supply, supports internal trigger, external trigger and manual trigger mode, to meet the low voltage test requirements of circuit breakers of different voltage levels.

For AC switches or permanent magnet switches, supports external high current drive to solve the problem of excessive coil current.

Personalized adaptation of sensors and software

Can expand three-way sensor collaborative measurement, or use a single sensor to virtually infer multi-phase data to reduce installation complexity.

The software supports custom parameter settings (such as speed definition, reclosing time), and adapts to customer-specific test standards.

Efficient data management and output

One-click generation of WORD reports for test results, supports QR code scanning to enter device information, and seamless connection to enterprise databases.

Provide cloud data upload function to achieve remote collaboration and long-term tracking analysis.
