Product Description

Product introduction

The high-voltage withstand test of electrical equipment is one of the most important items stipulated in the "Insulation Preventive Test". The withstand voltage test can be divided into AC withstand voltage test and DC withstand voltage test, and AC withstand voltage test can be divided into power frequency, frequency conversion and 0.1Hz ultra-low frequency test technology. Committee-recommended technique. Our company's new generation of this series of ultra-low frequency high-voltage generators is a core product independently developed by the latest American technology. It adopts a 7-inch touch screen, the latest ARM7 single-chip microcomputer, high-speed AD acquisition circuit, and is equipped with background management software. It overcomes many shortcomings of similar domestic products (see Table 1), and its cost performance is much higher than that of similar imported products. It is especially suitable for electrical equipment with large insulation equivalent capacitance (such as power cables, power capacitors, large and medium-sized generators and Electric motors, etc.) withstand voltage test, in line with the requirements of the newly promulgated power industry standard "General Technical Conditions for Ultra-low Frequency High Voltage Generators DL/T849.4-2004" in 2004.
