The DC high-voltage generator is an essential tool for the maintenance and testing of power supply, mining, aluminum and iron industries and other power supply departments. There is no regular unit that tests as usual without the DC high-voltage generator. The importance of the device.
The old-fashioned DC high-voltage generator (representing HB-ZGF of Huabao Electric) adopts the principle of power frequency voltage doubler and injected transformer oil as the insulating medium. Defects hindered his popularity, which has long since been eliminated and will not be described here.
The new type of DC high voltage generator (representing HB-ZGZ such as Huabao Electric) adopts high-frequency or intermediate-frequency voltage doubler circuit, and uses PWM pulse width modulation technology and high-power IGBT device design and production. In addition to low-voltage overcurrent, low-voltage overvoltage, high-voltage overcurrent, high-voltage overvoltage, zero protection, ungrounded protection and other functions, it also has full-range smooth voltage regulation, coarse voltage adjustment, fineness, zero protection, 75 The% UDC1mA function button is convenient for relatively modern intelligent functions such as zinc oxide arrester test.
The intelligent DC high-voltage generator (representing HB-ZGF2009 of Huabao Electric) is an epoch-making intelligent test instrument developed and produced by Qingdao Pingdu Huabao Electric Co., Ltd. and Qingdao Huahao Electric Power Instrument Co., Ltd. The excellent characteristics of the two generations of instruments overcome the shortcomings that manual operation and debugging accuracy are difficult to control. It is the best choice for the replacement of DC high-voltage generators, large-scale and large-angle viewing tests.
1. SCM controls automatic / manual boost, buck, timing, judgment, buck
2. Multi-window display high-end voltage, current and withstand time
3. "No knob" program-controlled voltage regulation can output positive and negative high voltage, and the output voltage can be set arbitrarily
4. "Infrared" high-end current sampling, the measurement results are accurate and true, can be accurate to 0.1μA
5. Perfect over-current and over-voltage zero protection, set protection current and withstand time arbitrarily
6. Program-controlled display brightness adjustment to adapt to different lighting environments and personal preferences
7. RS-232 / 485 remote communication and control port. The detailed description of its working principle and usage method is too large to be elaborated one by one. Interested friends can enter HB-ZGF2009 in our company's website search to locate Post download
Convenient folding for long battery life.
