YDQ (J.Z) Gas Testing Transformer: Technical Overview and Field Application

The YDQ (J.Z) Gas Testing Transformer represents a significant advancement in high-voltage insulation testing, utilizing modern SF6 gas insulation technology. Designed for evaluating the dielectric strength of various electrical equipment, it is particularly well-suited for field applications due to its portability, reliability, and maintenance-free operation.

Key Features

1.Portability & Compact Design – The unit is significantly lighter (40–65%) compared to conventional oil-filled transformers of equivalent capacity, making it ideal for on-site testing and transportation.

2.Clean & Maintenance-Free – Unlike oil-type transformers, the SF6 gas insulation eliminates oil leakage risks, reduces environmental contamination, and requires minimal maintenance.

3.All-Weather Operation – Performance remains stable across varying climatic conditions, allowing for continuous testing without interruptions.

4.Superior Dielectric Performance – SF6 gas provides higher dielectric strength compared to oil, with minimal corona effect, ensuring accurate and reliable test results.

Technical Specifications Overview

The YDQ series offers a wide range of models with capacities from 1.5 kVA to 50 kVA and output voltages of 50 kV, 100 kV, 150 kV, and 200 kV. Key parameters across models include:

1.Low Voltage Input: 200 V or 400 V

2.High Voltage Output: Up to 200 kV

3.Impedance Voltage: Typically ≤ 10%

4.No-Load Current: < 4%

5.Temperature Rise: Within limits over 6-minute operation

6.Weight & Dimensions: Optimized for field mobility, with weights ranging from 30 kg to 140 kg depending on model.

Example models include:

1.YDQ-10/50: 10 kVA, 50 kV output, 60 kg

2.YDQ-30/100: 30 kVA, 100 kV output, 110 kg

3.YDQ-50/150: 50 kVA, 150 kV output, 140 kg
