Specific Application of Non Partial Discharge Inflatable Test Variable

1. Manufacturing and factory inspection of power equipment

Non partial discharge inflatable test transformers are widely used in the field of power equipment manufacturing for power frequency withstand voltage testing and partial discharge detection of key components such as transformers, transformers, high-voltage switches, GIS (gas insulated switchgear), etc. For example:

Transformer manufacturing: Verify the voltage resistance performance of insulation materials to ensure no partial discharge (partial discharge ≤ 5pC) at rated voltage.

Cable and motor testing: Detect the insulation strength of the cable insulation layer and motor winding to avoid the risk of corona or breakdown during operation due to minor defects.

High voltage switchgear: Simulate the high voltage environment under actual working conditions before leaving the factory to ensure its arc extinguishing performance and long-term stability.

2. On site maintenance and fault diagnosis of power systems

In the operation of the power grid, this equipment is used for on-site high-voltage testing, especially suitable for scenarios such as substations and transmission lines:

GIS equipment testing: Periodic testing of the sealing and insulation status of gas insulated equipment to prevent malfunctions caused by gas leaks or pollution.

Assessment of old equipment: Determine the degree of insulation aging through partial discharge testing, providing a basis for maintenance or replacement.

Sudden fault analysis: Quickly locate partial discharge points in transmission lines or equipment to reduce power outage time.

3. Research and teaching experiments

In universities, research institutes, and third-party testing institutions, this equipment is the core tool for high-voltage technology research and teaching demonstrations

New material research and development: Testing the performance of new insulation materials (such as nanocomposites) under high electric fields.

Research on partial discharge mechanism: Analyze the relationship between discharge mode and insulation defects through precise partial discharge measurement (such as ≤ 3pC at 80% rated voltage).

Teaching and practical training: Provide students with a high-voltage test operation platform to visually demonstrate the process of insulation failure and protective measures.

4. New energy and special industry applications

With the promotion of new energy technologies, their applications in fields such as wind power and photovoltaics are increasing day by day

Wind power converter testing: Verify the insulation reliability of offshore wind power equipment in humid and salt spray environments.

Photovoltaic inverter testing: Ensure the voltage resistance performance of photovoltaic power plant components in high-altitude areas.

Rail transit and aerospace: used for high-voltage component testing of high-speed rail traction transformers and aircraft electrical systems, meeting safety standards in harsh environments.

5. Quality inspection and standardization certification

As a testing equipment that complies with international standards such as IEC and GB, it plays a key role in certification bodies:

Type test: Verify whether the new product complies with industry standards (such as IEC 60270 partial discharge measurement standard).

Third party certification: providing authoritative testing reports for power equipment, supporting market access and bidding requirements.

Environmental assessment: Reduce environmental pollution through oil-free design (SF6 gas insulation), in line with the trend of green manufacturing.
