Portable DC Hipot
Portable DC hipotDC high voltage generator are researched and manufactured in light of China industry standard ZBF 24003-90 《Universal technology Conditions about portable DC Hipot Tester》.They are applicable to the electric power branch, power department of factories , scientific research units, railway, chemical industry, power plants,which use them to do test on zinc oxide arrester ,magnetic blowing arrester, power cables, generators, transformers, switches and other equipments.They are used IF voltage circuit and the latest PWM technology to do closed-loop adjustment and used voltage feedback to improve voltage stability.The use of high power IGBT devices with excellent Performance and their drive technology,and the measures about special shielding, grounding and isolation in accordance with electromagnetic compatibility theory,all of this makes the DC high voltage generator high-quality, portable and can withstand the rated voltage discharge and prevent being damaged.The major advanced technology components of HF series DC high voltage generator equipment are made from the United States, Germany, Japan and other countries so that the equipments become more reliable and more stable.Feather:● It’s the smallest and lightest in the same types of products and looks more beautiful and reliable. Simple operation and complete function is easy for wild work.● DC high voltage generator are used the latest PWM technology, high power IGBT devices and voltage feedback to make the voltage stability higher,and the ripple coefficient smaller.● The major advanced technology components of HF series DC high voltage generator equipment are made from the United States, Germany, Japan and other countries so that the equipments become more reliable and more stable and can stay continuous discharge directly to earth.● The voltage meter and current meter all have high precision and exact measure and use figure display. The resolution of voltage meter is 0.1KV and current meter is 1 uA,The figure voltage meter displays is just the voltage on tested res and it needn’t additional Inductive Potentiometer(ipot).The high voltage end is used rotund shield figure meter so it can stay the shoot of discharge and has good performance of anti-jamming.● It has high stabilization of voltage regulation and regulates voltage Smoothly. The output voltage regulator uses a single multi-turn inductive potentiometer.● It has many functions such as cathode output, operating from zero, continuously adjustable, over voltage protection, over-current protection, back to zero protection, grounding protection, special disconnection protection.All technical indexs are better than industry standards.● The added high-precision 75% VDC-1mA functions makes it esay to do Zinc oxide Arrester tests. You just need to push it gently and the value will be displayed. There is a 75% VDC-1mA function button on the control box to do Zinc oxide arrester test. Push the 0.75 UDC - 1mA button when the current rises to 1000 uA. The value Data voltage meter and current meter shows is data of 75% .Then return the voltage ipot to zero immediately, and push the green button to cut off high-voltage power switch.● The over voltage set fuction uses number dial switch which can display the figures of voltage clear and makes it esay to operate it.The unit it displays on the dial is KV.● American technology and special design is used to voltage multiplier.This makes it easy to do tests.● Three hided supporting feet makes the voltage multiplier more stable(Apply to 200KV). The up cover of control box can be used as hurricane lamp base and cover the Voltage Multiplier to make it more stable.Specification:parameter technic60/260/5120/2120/3120/10200/2200/5200/10300/3300/5400/2Rated voltage（KV）Rated current（mA）Rated power（W）Voltage meter precisionnumber on voltage meter ±（1.0 %reading±0.2KV）Current meter precisionnumber on current meter ±（1.0 %reading±0.2KV） Ripple coefficient≤0.5％Voltage stabilizationstochastic wave ,≤1％ when power wave±10%Overloading abilityoverstep 10% of rated voltage when loading nothing for ten minutes; the biggest charge current can be 1.5 times of rated currentpowersingle-phase alternating current power of 50HZ 220V±10％workingincontinuous useThe time should be no more than 30 minutes when continuously use itWork conditiontemperature：-10～40℃relative humidity：≤85％ when room temperature is 25℃height above sea level：below1500 meterscapacitancecapacitance of the tested res is absolutenessCan be charged with 1.5 times of rated currentconfigurationelectric insulated Voltage Multiplier is made of epoxy FRP(Fiberglass-Reinforced Plastics)Air insulated、without leakcharacteristic of Control boxOne button for high precision of 0.75UDC--1mA（precision≤1.0％）is suit to do zinc oxide lightning arrester testovervoltage protection use dialing code set,be clear at a glanceInternational standard box withTwo kind of using way(can be take out from the box for using) makes it easy to use.
