Product name: HCYZ-X transformer on-load switch AC parameter test device
Category: transformer comprehensive test series
Detailed introduction
HCYZ-X transformer on-load switch AC parameter test device can be used for AC testing of the action characteristics of on-load tap-changers of various wiring groups, three-phase and single-phase transformers of 10kV-500kV, accurately capturing the current and voltage changes before and after the transient point during the switch switching process. For suspected switches, single-phase high voltage simulation of the actual operation state of the transformer can be performed under external pressure power supply to perform tap-changer. This device comes with a high-performance data analysis system, which is convenient for engineering and technical personnel to process on-site according to engineering needs, and can be exported for backup for later analysis.
This device is developed using an embedded system with stable performance. The 7-inch capacitive touch screen and shortcut keys are used together to make on-site operation simple and fast. Test reports can be directly generated on-site. At the same time, the USB interface can be connected to an external mobile storage device to import and export data, which is convenient for users to backup and import analysis.
