The non-PD variable frequency series resonant withstand voltage device is an advanced test equipment, and its core function is to check the insulation withstand level of various insulating materials, structures and electrical products under power frequency voltage. This equipment is not only a non-partial discharge power frequency test power supply for transformers, transformers, lightning arresters and other test products, but also widely used in electrical manufacturing, power operation, scientific research and higher education. It can carry out partial discharge and AC withstand voltage test on high-voltage electrical equipment, such as transformers, GIS, transformers, switches, bushings, lightning arresters, cables, etc., and is also suitable for power frequency AC withstand voltage testing of insulating materials.
Features: Extremely small partial discharge: The partial discharge of the device design is small, which ensures that the partial discharge of the system is within the range of 5pc (special requirements can be customized) to ensure the accuracy and reliability of the test.
High-voltage insulated outer cylinder: The shell is made of epoxy resin casting, and the halo-free high-voltage insulated outer cylinder is wound with glass filament to enhance the safety and stability of the equipment.
Complete functions: the complete set of equipment has low impedance, overvoltage and overcurrent flashover protection and other functions are readily available to ensure the safety of the test process.
Lightweight equalizing hood: processed by special mold, aluminum plate forming, smooth surface, light weight, easy and fast installation.
Intelligent measurement and control system: Through the selection of power frequency intelligent measurement and control system, the intelligent and automated level of system control and protection is improved.
Optical fiber communication and sampling: Optical fiber communication and sampling technology are used to ensure the complete isolation of high-voltage and low-voltage control loops and improve the safety of the system.
Real-time status self-check: The test process can be real-time status self-check and display, which is convenient for users to grasp the equipment status at any time.
Data management function: It has a complete data and report management function, which is convenient for users to sort out and analyze the test data.
Curve drawing: It can record and plot the test curves of high pressure u t and i t, which provides strong support for the visual analysis of test data.
