The intelligent power frequency withstand voltage test device for the power system has superior performance

YDJ(Z)-5KVA/50kVIntelligent power frequency withstand voltage test deviceAdopting a single frame core structure. The primary winding is wound around the iron core, with the high-voltage winding outside. This coaxial arrangement reduces leakage flux and thus increases coupling between windings. The outer shell of the product is made into an octagonal structure that matches well with the core, giving the overall appearance a beautiful and elegant look. The external structural diagram is shown in Figure 1, and the internal structural diagram is shown in Figure 2.

In YDJ (G) and TDM (G) test transformers, a and x are low voltage input terminals, E and F are instrument measurement terminals, and A and X are high voltage outputs. There is no high-voltage silicon stack in the YDJ (G) series.

YDJ (G) and TDM (G) type test transformers are single-phase transformers, connected to group I. I. They are connected to the XC/TC series operation box (set) using a power supply of 220V (380V above 10KVA) at the power frequency. This is a special equipment for test transformers produced by our company, and detailed information can be found in its specific user manual. The voltage is adjusted to 0-200V (or 0-400V) through an autotransformer (attached to the regulator above 50KVA) inside the operation box and output to the initial winding of YDJ (G) and TDM (G) test transformers. According to the principle of electromagnetic induction, the high voltage required for the test can be obtained in the high-voltage winding of the test transformer.

YDJ(Z)-5KVA/50kVIntelligent power frequency withstand voltage test deviceIt is a specialized supporting equipment for the lightweight test transformer produced by our company. The control box has the characteristics of easy use and maintenance, superior performance, safe and reliable use, beautiful appearance, durability, and easy mobility. It is power supply enterprises, large factories, metallurgy, power plants, railways, etc. that require power maintenance departmentsequipment
