HZ-G35A Integrated High Frequency High Voltage Power Supply
HZ-G35A Integrated High Frequency High Voltage Power Supply
HZ-G35A is huazheng electric's newly developed innovative integrated high-voltage power supply product, with the advantage of stable performance, leading technology, portable and safe. The equipment meets the "Standards of the Electric Power Industry of the People's Republic of China-General Technical Requirements for High Voltage Test Equipment". This product adopts the principle of switching power supply and can output maximum 35KV DC negative high voltage. The device is equipped with built-in capacitor, vacuum shock ignition, emergency stop, and automatic discharge functions, making it safe and reliable. When used with any cable fault tester produced by our company, it enables easy application of the multiple pulse method or current flashover method for rough measurement, pre-location, or accurate pinpointing of cable faults.
Performance characteristics
1. Integrated design, built-in capacitor, simple wiring.
2.Touch screen, simple setting and operation, intuitive and convenient display.
3. With voltage regulation, automatic voltage stabilization and automatic protection functions.
4. The output high voltage features both single-pulse and continuous-pulse operation modes.
5. The output high voltage has a DC output, which can work with an external ball gap, and has a variety of applications.
6. The software controls vacuum impulse ignition and discharge, self-adaptive discharge and pulse period.
7. With emergency stop button, automatic discharge function, safe and reliable.
8. The continuous working time is not less than 6 hours, meeting the longest working time of cable fault test.
9. Engineering chassis design, compact structure, small size, light weight, easy to carry by one person.
Technical parameters
This product is mainly used for impulse discharging when sample high-resistance fault waveforms of power cable of 35KV and below, and for impulsive discharge when precisely locate fault point. It can also be used for the burn-through of high-resistance faults of power cables and external sheath precisely locating for extra-high voltage cables above 110kV. It can burn through the breakdown point in a short time and reduce resistance in the breakdown point.
