DC high voltage generator overcomes three difficult problems
The DC high-voltage generator easily overcomes the three difficult problems of over-current, breakdown, and over-voltage. In fact, it uses pulse-width modulation (PWM) technology, IGBTs, and advanced electronic circuits and components. It has an output that is immune to disturbances in the power grid and has zero Protection measures such as over-current, over-current, breakdown, over-voltage, etc., no matter over-current, breakdown, or over-voltage protection circuit can quickly operate, effectively guarantee the safety of equipment and personnel. The instrument is a device that provides high-voltage DC source, in the use of DC high voltage The generator must be grounded reliably before the generator. DC voltage generator voltage and current meter are digital display, voltage resolution is 0.1kV, current resolution is 0.1uA, the voltage meter on the control box is directly displayed on the load sample. Voltage value, no need to use external voltage divider, the wiring is simple. The instrument has high and low voltage side to measure leakage current, and the high voltage end adopts round shield digital meter display. It is not afraid of discharge shock and has good anti-interference performance. It is suitable for field use.
The DC high voltage generator adopts new technologies, new materials and new devices in the 1990s. It has the characteristics of large output power, small size, and light weight. It has reliable over-voltage, over-current, and zero closing protection functions, with 0.75 times. The voltage latching function is equipped with a time relay that can set a regular voice alarm in the test. The entire instrument is easy to carry, easy to operate, safe and reliable, especially suitable for field tests in the power sector. The DC high voltage generator adopts an intermediate frequency voltage doubler circuit and applies PWM pulse width modulation technology and high power IGBT devices. According to the theory of electromagnetic compatibility, using special shielding, isolation and grounding measures, the adjustment accuracy is high, the operation is simple, the volume is small, the weight is light, and it is convenient for the power department, the enterprise power department to the zinc oxide arrester, power cable, generator, transformer, switch Equipment such as DC high voltage test.
DC high voltage generator picture
The new-generation DC high voltage generator adopts a high-frequency voltage doubler circuit. It adopts the latest PWM high-frequency pulse width modulation technology and adopts a large-voltage feedback to apply the latest PWM high-frequency pulse width modulation technology. The voltage stability is greatly improved. DC high-voltage generators use high-performance IGBT devices and their driving technologies, and according to electromagnetic compatibility theory, special shielding, isolation, and grounding are used. Makes DC high voltage generators achieve high quality, portable, and can withstand rated voltage discharge without damage to the ring.
When the DC high-voltage generator uses lightning arresters for lightning protection, the arrester grounding line, the transformer neutral line and the transformer shell are grounded using a "triple-in-one" approach. If the high-voltage side experiences a lightning strike during the operation of the transformer, it will cause the arrester to discharge, and the residual pressure generated will act on the high-voltage winding. Because the impedance of the high voltage winding is very large and the capacitive reactance is very small, the lightning current only flows through the high voltage winding and the capacitor on the ground. When the circuit discharges through the ground point, it will produce a large impact voltage drop on the ground resistance. This voltage passes through. Neutral lines will also be applied to the low voltage windings, and the low voltage windings will also generate magnetic flux through the lightning current. According to the principle of electromagnetic induction, the DC high-voltage generator generates a very high induced voltage on the high-voltage winding according to the change of the transformer. This voltage is called “inverted overvoltageâ€. The magnitude of the voltage is several times to several tens of times larger than the residual voltage, and it also causes breakdown of the transformer insulation and damage.
