In the field of high-voltage testing, lightning impulse voltage generators have long been regarded as equipment with high professional requirements and difficult operation. Complex wave tuning, tedious parameter settings, and strict requirements for operators - these inherent impressions make many power equipment manufacturers worry when purchasing: will the equipment be idle due to too complex operation? Will spending a lot of time tuning the waves during each experiment affect production efficiency?

The UHV series lightning impulse voltage generator test device of Wuhan UHV Power Technology Co., Ltd. is changing this situation. The device is designed with the concept of "easy wave adjustment, simple operation, good synchronization performance, and reliable action", which transforms lightning impulse testing from an "expert level" task to a routine operation that ordinary technicians can handle.

Wave tuning is no longer difficult: a set of equipment can easily output standard waveforms

The difficulty and most of the work in impulse voltage testing lies in wave modulation. Factors such as the connection method of test samples, test equipment components, and the distance between surrounding grounding bodies can all affect the output waveform. Obtaining a shock waveform that meets standard requirements is the key to impact testing.

The Wuhan UHV series equipment has undergone systematic optimization in terms of wave modulation convenience. The device adopts a design with small loop inductance and band stop filtering measures, which can stably output standard shock waves even when facing large capacitive loads, and has a very strong load capacity. Operators do not need to repeatedly adjust complex circuit parameters to quickly obtain lightning full wave, cutoff wave, and operation wave.

An engineer of the cable factory who used the equipment once fed back to the Wuhan UHV after-sales team: "Previously, wave modulation would take more than half a day, but now we can basically adjust the waveform in half an hour, and the production efficiency has improved significantly."

Fully automatic control system: one click operation, automatic completion

The equipment is equipped with a Siemens PLC fully automatic control system, which supports constant current voltage regulation, automatic ball distance tracking, and continuous cycle testing. Manual and automatic modes are optional. The operator only needs to set the parameters, and the system can automatically complete the entire process of charging, triggering, waveform acquisition, and analysis.

In terms of parameter settings, the charging voltage setting range of the device is 0-800kV, with a setting deviation of ≤± 1%, and the charging time is adjustable from 30-180s. Protection settings such as overcurrent and overvoltage can be flexibly set. Easy polarity switching, one click switching between positive and negative polarities. These designs significantly lower the skill threshold for operators, and ordinary technicians can independently complete experiments after simple training.

The supporting weak damping capacitor voltage divider and high-speed oscilloscope come with professional analysis software that can automatically analyze waveform parameters and generate test reports. After the experiment is completed, data is automatically recorded and reports are generated, eliminating the tedious process of manually organizing data.

Modular design: reduced volume, easier maintenance

The convenience of daily maintenance of equipment also affects the long-term user experience. The UHV series adopts a 4-stage tower modular design, supporting single-stage low-voltage testing and multi-stage parallel expansion. Modular design reduces the size of equipment by 40% compared to traditional devices. Make it easy to transport .

In terms of maintenance, the modular structure means that only specific modules need to be operated during maintenance, without the need for complete machine disassembly. The replacement of key components is convenient and fast, greatly reducing equipment downtime. The device also supports wide temperature operation from -30 ℃ to 50 ℃, with strong environmental adaptability, reducing maintenance frequency caused by environmental factors.

Manufacturer on-site training: from "knowing how to use" to "using it well"

No matter how simple the device operation is, it cannot be separated from system training. The Wuhan UHV after-sales team has been invited multiple times to customer sites to provide product technical training for operators, ensuring that customers can proficiently operate and understand the principles of the equipment.

At a customer site in Beijing, the customer mainly produces 10kV vacuum circuit breakers and requires factory lightning impulse testing. After the Wuhan UHV after-sales personnel arrived on site, with systematic explanations and practical guidance, the customer's technical personnel were quickly able to independently complete the instrument wiring and voltage boosting test. The on-site person in charge of the customer expressed great satisfaction with this training service.

For power equipment manufacturers, a high-voltage testing equipment that is complex to operate and difficult to maintain, no matter how high its technical specifications are, may ultimately be shelved. The Wuhan UHV series lightning impulse voltage generator, with its user-friendly design of "easy wave modulation and simple operation", fully automatic control system, modular and convenient maintenance structure, and comprehensive manufacturer training services, has transformed lightning impulse testing from an "expert activity" to a "routine activity", truly achieving buyback, usability, and good performance.
