The use of DC high voltage generator

July 26, 2023

DC high-voltage generator adopts high-frequency double voltage circuit, takes the lead in applying the latest PWM high-frequency pulse width modulation technology, closed-loop adjustment, adopts large voltage feedback, greatly improves voltage stability, and uses high-performance IGBT devices with excellent performance and its Drive technology, and according to electromagnetic compatibility theory, using special shielding, isolation and grounding measures, so that DC high voltage generator achieves high quality, portable, and can withstand rated voltage discharge without damage.
Current limiting resistor instructions
1. Current limiting resistor function: When the test piece breaks down or flickers, it acts as a limiting current, so as not to damage the test equipment.
2. How to use: As long as the end of the current limiting resistor M10 nut screwed to the top of the DC high pressure doubler cylinder, high pressure output line bolts can be. If you want to connect in series high pressure microampere meter (optional optional SWB-V type table) , as long as the bottom of the micrometer table M10 nut screw on the other end of the current limiting resistor.
3. If a smart DC high voltage generator is used, when the sample is a zinc oxide surge arrester, a general valve arrester, and a high voltage switch, etc., the current limiting resistor may not be used. That is, if a small current or small capacitance test item is used, the current limiter may not be limited. resistance.
4. Large-capacity test items such as power cables, transformers, and motors should be tested in series with a current limiting resistor in the high-voltage loop to protect the test equipment.

Tower Crane Gear

Tower Crane gear mainly including 19/38/99 teeth gear, bevel gear, Tower Crane Sun Gear, and so on, which are the critical parts of the tower crane reducer. 19 teeth gear and 38 teeth gear are connected with two motor shaft repectively, which are connected with 99 teeth gear. The speed is reduced by the transmission of gears.


A bevel gear is a type of gear that has teeth cut on a conical surface. It is commonly used in tower cranes to transmit power between the vertical and horizontal shafts.
In a tower crane, the bevel gear is typically used to change the direction of rotation. The vertical shaft, which is connected to the motor, rotates vertically, while the horizontal shaft, which is connected to the crane's boom, rotates horizontally.
The bevel gear consists of two gears with intersecting axes. The teeth on the gears are cut at an angle, allowing them to mesh smoothly and transmit power. The gear ratio of the bevel gear determines the speed and torque of the rotation.
The bevel gear in a tower crane is designed to withstand heavy loads and provide efficient power transmission. It is usually made of high-strength steel to ensure durability and reliability in demanding crane operations.
Overall, the bevel gear plays a crucial role in the functioning of a tower crane by enabling the transfer of power and changing the direction of rotation between the vertical and horizontal shafts.
