Core performance and functional characteristics
The performance characteristics of this series of inflatable test transformers are reflected in multiple aspects.
1. Its output voltage range can cover the needs of most conventional high-voltage tests, such as AC/DC withstand voltage tests for power equipment such as transformers, high-voltage switches, and lightning arresters. Due to the excellent insulation and arc extinguishing characteristics of SF6 gas, the noise level of the equipment during operation is low, creating a relatively quiet working environment for the site.
2. Equipment is usually equipped with overcurrent, overvoltage and other protection functions. These protective measures can quickly cut off the power supply in case of accidental flashover or breakdown of the test circuit, which to some extent protects the safety of the test sample and the test transformer itself, and reduces the risk of accidental damage. The equipment also has the characteristics of stable voltage rise and fall, continuous and smooth adjustment, which facilitates the operator to accurately control the test voltage.
3. The product has strong universality and can be easily connected to supporting equipment such as operation boxes and controllers to form a complete high-voltage testing system, meeting the combined application needs of different users and different testing scenarios.
Core application areas
The manufacturing and maintenance of power equipment is the core application scenario of YDQ test transformers, mainly used to inspect whether the insulation strength of various power equipment is qualified and ensure its safe operation.
Handover test and preventive test of power plant and substation equipment:
Power transformer: Conduct power frequency AC withstand voltage test and DC withstand voltage test to check the strength of the main insulation and longitudinal insulation.
High voltage switches (circuit breakers, isolating switches, GIS combination devices): Conduct a voltage withstand test between the broken and conductive parts and the ground to verify their insulation performance.
Power cables: Conducting DC withstand voltage tests and measuring leakage current is an important means of inspecting the insulation condition of cables after installation.
Transformer (CT/PT): Conduct power frequency withstand voltage test to ensure its insulation meets operational requirements.
Lightning arrester: Conduct DC reference voltage test and leakage current test.
High voltage electrical equipment manufacturer:
As a factory inspection equipment on the production line, strict voltage withstand tests are conducted on every switch, transformer, mutual inductance and other product produced to ensure that the product quality meets national and international standards.
