Transformer AC DC Hipot Test Set 5kVA 50kV

Product Introduction

This series of test transformers represents our company's latest generation of products, developed through enhancements to the original TDM model.

The unit delivers smooth AC voltage output ranging from 0 to 250V and incorporates multiple monitoring and protection functions. It is designed for use with test transformers, current boosters, and other electrical testing equipment.

Product feature and application

1. Monitoring Functions: Output Current Instrument Voltage Zero Position Indication Closing/Opening Indication Timing Indication

2. Protection Functions: Overcurrent Protection Time Relay

3. Incorporates a new-generation time relay for an extended timing range.

4. Utilises a new-generation current relay for enhanced precision and reliability, ensuring personnel and equipment safety.

5. Rational structure, compact size, and lightweight design.

6. Insulation configuration: Employing the 'distance effect' principle of transformer oil, multi-layered insulation divides internal insulation into multiple oil channels, enhancing insulation integrity while reducing overall volume.

7. Resolves oil leakage issues in TDM series transformers. As TDM series transformers lack oil reservoirs, oil expansion during high temperatures causes leakage from oil nozzles. This series positions the oil filling port atop the bushings, connecting the oil within the bushings to that within the core. Thus, these bushings serve not only to house silicon stacks, short-circuit rods, and series excitation rods, but also function as the transformer's oil reservoir.

8. This series employs metal fixed leads and voltage equalisation, thereby eliminating discharge phenomena.

9. The tank features a compact structure, novel appearance, small footprint, and light weight.

10. The core employs a single-frame design using DQ-type 0.30mm cold-rolled grain-oriented silicon steel laminations, secured with novel specialised fasteners replacing conventional core-penetrating bolts. The coil adopts a concentric cylindrical, multi-layer tower structure.

FAQ

1)how does a ac dc hipot tester work ?

1. Correctly connect the wiring and turn the voltage regulator counterclockwise to the zero position. (The voltage cannot be increased unless the regulator is at zero.)
2. Set the 'time relay' and 'current relay' according to the test requirements.
3. Plug in the power cord; the power indicator light illuminates. Press the switch-on button; the power supply indicator light illuminates. (Voltage can now be increased.)
4. Rotate the voltage regulator handle clockwise at a steady pace to the required value.
5. Activate the timing switch; the 'timing buzzer alarm' sounding indicates the time has elapsed.
6. Turn the voltage regulator counterclockwise to zero position. Press the disconnection button; the power supply indicator extinguishes.
7. Disconnect the power cord and remove wiring. The power indicator extinguishes, concluding the test.
