With the continuous updating of the design methods of series resonant devices (also known as resonant devices), series resonant devices also have stronger practical performance. Therefore, its application in experimental devices has become more widespread. Below, a specific analysis and discussion will be conducted on the application of the series resonance experimental device.
The series resonant device was applied in cable testing, and it was found that temperature has a significant impact on resistivity. Therefore, when using a series resonant device for cable testing, it is necessary to control the temperature reasonably to avoid reducing the effectiveness of the test. In addition, inside the cable, the DC voltage is affected by various factors, which can easily accumulate spatial charges and lead to insulation flashover in cable accessories. This can result in local voltage enhancement due to pilot control, which can easily lead to insulation breakdown during the test, posing a certain threat to the safety of the test. In addition, during certain DC withstand voltage tests, it is easy for cables to be punctured, which can damage the cables that are operating normally. The application of series resonant devices in cable testing can effectively prevent such situations from occurring. In addition, due to its small size and strong flexibility, series resonant devices have been widely used in cable testing.
GIS equipment, also known as gas insulated switchgear, is mainly used to transport tested and qualified products to the site for certain assembly. However, when transporting certain components or firmware, it is easy to experience loosening or displacement due to vibration or impact, which not only reduces transportation efficiency to a certain extent, but also brings certain economic losses. However, by applying series resonant devices in GIS equipment, anomalies in the electric field structure can be effectively detected, thereby effectively reducing the probability of accidents. Therefore, we should effectively apply series resonant devices in GIS equipment and continuously conduct voltage withstand tests on site to effectively avoid safety accidents.
When used in the AC withstand voltage test of generators, due to the large size of the generator and the use of conventional high-capacity testing equipment, once the insulation of the generator stator winding is broken down, a large fault short-circuit current is likely to occur, which can cause damage to the iron core. Through the use of a certain series resonance device in the AC withstand voltage test of the generator, the pilot holding company can effectively change the inductance by utilizing the air gap of the iron core, thereby achieving working resonance and effectively protecting the iron core in the generator from damage.
Conclusion
High voltage testing is an important means of testing the insulation performance of electrical equipment, and the efficient application of series resonant devices in high-voltage testing plays a crucial role in improving the safety performance of various components in the power grid. Therefore, HV Hipot Electric Co., Ltd. pilot holding company should first understand and comprehend the relevant overview of series resonance, and then understand the advantages and principles of applying series resonance to high-voltage testing, in order to effectively apply series resonance devices to cable testing, GIS equipment, and generator AC withstand voltage testing, and continuously improve the effectiveness of high-voltage testing to effectively detect the insulation performance of electrical equipment.
