Yangzhou Darui Co., Ltd. professionally produces the Top brand TPNYJ power frequency withstand voltage test device, which is a new type of power frequency high voltage test device produced after improvement according to the requirements of the electric power industry standard DL/T 848.2-2004. This device has the characteristics of small size, light weight, complete functions, compact structure, and convenient use. It is suitable for power, industrial and mining, scientific research and other departments, and is used for power frequency withstand voltage tests on various high-voltage electrical equipment, electrical components, and insulating materials. It is an indispensable equipment in high-voltage testing.
Product Structure
The step-up transformer of the TPNYJ power frequency AC withstand voltage test complete device is a single-phase transformer with connection group label II. The iron core of the step-up transformer part is a single-frame type. The coil adopts a coaxial cylindrical multi-layer tower structure. The primary low-voltage winding is wound on the iron core, and the secondary high-voltage winding is wound on the outside of the low-voltage winding. This coaxial arrangement reduces the coupling loss between windings. The shell of this high-voltage test device is made into an octagonal structure that fits well with the core, and the overall appearance is beautiful and generous.
Working Principle
The AC output working process of this high-voltage test device is as follows: connect the AC 220V voltage to the power control box, adjust the 0~200V voltage through the auto-transformer in the power control box to the primary winding of the AC withstand voltage test device. According to the principle of electromagnetic induction, the AC high voltage required for the test can be obtained in the high-voltage winding of the high-voltage test device.
