HZG-3KVA/50KV Dry Type Hipot Test Equipment

I. Product Introduction
This series of transformers is manufactured using advanced production equipment and innovative technologies, including epoxy vacuum casting for coil winding and a CD-type iron core. These advancements significantly reduce weight and volume while enhancing insulation strength and humidity resistance. The design effectively minimizes magnetic leakage, greatly improving the transformer's ability to withstand short-circuit current impacts during testing.

These products are characterized by their lightweight construction, compact size, aesthetic appearance, and stable performance. They are easy to operate and transport, making them especially suitable for on-site applications. As a new generation of high-voltage testing transformers in China, they support both AC and DC tests. They are widely used in power systems and by power consumers for on-site insulation performance tests of electrical equipment, as well as providing high-voltage DC and small-current power sources for various voltage systems or devices.

Precautions

The insulating testing products of high voltage appliance should be safe and correct. In addition to know well the manual of this product, the operation must be implemented in accordance with relevant national standards and plans: GB/T16927-1996 High-Voltage Experimentation Technology and DL/T596-1996 Preventive Testing Regulations for Electrical Equipment.

Due to the design characteristics and structure limitation of this series products, continuous operation under rated output capacity should not exceed 2 hours. If the products need to be used again, the power can be connected until power off for 2 hours. Continuous operation can be done under two thirds of rated voltage and two thirds of rated current.

In normal insulation of high voltage appliance, this series products are not allowed to operate in case of exceeding rated output voltage.

When this series products consist of cascade high voltage test, users should pay special attention to check the correctness of conditions and wiring of Class 2 and 3 transformer's main body and insulating bracket, as well as the protective grounding of entire system and conditions of protective grounding.
