main feature:
1. One hundred pilot brand portable DC high voltage generator adopts computer control technology in the industry to control PWM pulse width modulation, measurement, protection and display, display output DC high voltage, current, over voltage setting, timing and protection information on LCD display. , And with RS232 interface to communicate with the computer.
2, the portable card pliant first to use DC high voltage generator section structure, i.e. both for the high voltage level, but for the lower voltage level, and to maintain its accuracy is preserved. At 100 / 200kV / 2mA section two, for example, when to do single 100kV / 4mA use, the system can be used to 35kV DC high voltage electrical equipment test, this time can be avoided to ensure the accuracy of the measurement Mara car; two When used, it can be used for 200kV/2mA. It can be used for 220kV sub-section, 110kV and below zinc oxide arrester DC test and DC withstand voltage test of cross-linked cable. A truly dual-purpose machine greatly facilitates the use of on-site users.
3, 100 test brand portable DC high voltage generator first intelligent ground fault protection and alarm function (poor grounding can not be boosted), pressure measuring circuit loop protection (voltage measurement loop circuit disconnection instrument can not boost), emergency stop button, greatly improve The safety of the operator during the operation.
4, 100 test brand portable DC high voltage generator adopts 30-50kHz high frequency doubler circuit, take the lead in applying the latest PUM pulse width modulation technology and high power IGBT devices, and according to the electromagnetic compatibility theory, using special shielding, isolation and grounding measures The DC high voltage generator is realized with high quality, and the intelligent DC high voltage generator can withstand the rated voltage discharge without damaging the machine.
5, 100 test brand portable DC high voltage generator adopts large voltage feedback, so that the voltage stability is greatly improved, specially designed 0.75UDC-1mA trigger button for the zinc oxide arrester test, also increase the frequency to 30-50KHz, so that the control The volume and weight of the box and doubler cylinder have been greatly reduced, which is more convenient for on-site use.
6, high-frequency DC high voltage generator selection of United States, Japan and other advanced technology components and the German-made international series chassis, set practical and aesthetic as one.
7. The double pressure cylinder of the 100-step brand portable DC high voltage generator is developed with German technology; the intermediate frequency transformer is specially designed by the relevant experts, with small size and large capacity. Double-pressure cylinder base contains â–³-Y legs, that is, when it is used, it develops into a Y-shape. The support is stable and convenient. When packing, it shrinks into a delta shape and is hidden in the base.
8, the portable hundred test card having a plurality of DC high voltage generator protection functions, such as: low-voltage over-current, over-voltage low-voltage, high-voltage over-current, over-voltage high voltage, zero protection, protection is not grounded. Fault sampling uses a dedicated sensor, the action time is nanoseconds, optical isolation elements are also nanoseconds, and the operation time is generally 10 microseconds to completely shut off the DC main loop. Promote rapid shutdown signal dedicated sensor sampling at the output, the reaction time is nanosecond by nanosecond optical isolator element and the analog switch nanoseconds, microseconds, the entire process in the amplifier circuit 2 is driven signal Cut off to ensure that the output device does not damage the power device in the event of a short circuit.
9. The fully shielded automatic high-voltage microampere meter equipped with a high-frequency test-brand portable DC high-voltage generator adopts a metal shell. The liquid crystal display uses a conductive glass and the shell is connected. The table shell has no buttons, and the test wire is coaxial with the shielding wire. Lead out, so as to achieve a true full shield; ammeter for the 4 1/2 digit display, can be 0-200-2000μA automatic shift, a larger increase in the resolution of the leakage current.
One hundred brand portable DC high voltage generator, industry preferred
