DC High Voltage Power Supply for Impulse Discharge During Cable Fault Location and DC Withstand Voltage Test

Product Description

Product Description

XHHV508-4 DC high voltage power supply is mainly used for impulse discharge during cable fault testing at voltage levels of 35kV and below; it can also be used for DC withstand voltage testing of other electrical equipment. This equipment completely replaces the traditional test transformer and operating box weighing dozens of kilograms (generally a set of 5kVA transformers weighs more than 50 kg, and the control box weighs more than 20 kg).

This power supply uses high-precision, high-stability dedicated high-voltage electronic components and high-frequency high-voltage technology to make its overall structure simple and ultra-light. In order to retain people's original habit of using transformers and operating boxes to generate DC high voltage, this power supply adopts a humanized design and operation method, which is safe and reliable. It truly achieves the effect of being indestructible by impact, and the high voltage can work normally even if it is short-circuited to the ground. It is currently the lightest portable DC impact high-voltage equipment in China with any combination of capacity and the most humanized operation. It is the ideal product we have been dreaming of for power cable fault detection.

Features

★ With over-current, over-voltage, over-heating automatic protection function;
★ The impact discharge is uniform, and the discharge speed is controllable;
★ The super short-circuit protection function can make the high-voltage output directly short-circuit to the ground;
★ With current and voltage dual 1.5-level pointer meter display, intuitive and clear, the impact discharge process is clear at a glance;
★ High-voltage side voltage measurement, real-time and accurate; the high-voltage end is connected in series with a microammeter and can be used as a direct high-voltage generator;
★ With zero-position start protection, safe and reliable;
★ Unique self-discharge design, as long as the high-voltage output is cut off, the high voltage itself is zero;
★ Unique high-voltage measurement design, in the stopped state, the voltmeter can indicate the capacitor voltage in real time;
