The YDQ-10kVA/100kV gas-insulated test transformer is primarily designed for high-voltage testing of power equipment rated at 35kV and below. Although capable of an output voltage of 100kV, practical applications must adhere to industry standards regarding test voltage multipliers; it is suitable for insulation testing of small to medium-sized power equipment, including:

①　Distribution equipment: 10kV and 35kV distribution transformers.

②　Switchgear and bushings: Circuit breaker arc-extinguishing chambers, vacuum interrupters, high-voltage porcelain insulators, and bushings.

③　Insulated tools: Withstand voltage testing for high-voltage protective gear such as insulating rods, gloves, and boots.

④　Cable accessories: Terminations and joints for power cables rated at 35kV and below.

The equipment is mainly used to verify the insulation strength of the aforementioned devices, specifically through:

①　Power-frequency withstand voltage test: The primary application, used to assess insulation strength under power-frequency AC voltage.

②　Leakage current test: Conducted in conjunction with a DC generator (requiring a rectifier unit) or as a basic AC leakage test.

③　Specialized type tests: Used for educational experiments, material insulation breakdown testing, or fundamental laboratory research.

Utilizing SF6 gas as the insulating medium, this series offers advantages such as compact size, light weight, and immunity to environmental and climatic conditions, making it particularly well-suited for field operations and routine maintenance at substations.

Product Advantages:

①　Ultra-lightweight design, purpose-built for field operations

Utilizing high-dielectric-strength SF6 gas, the unit’s volume and weight are merely 40%–60% of those of traditional oil-immersed transformers. It can be easily transported by a single person, significantly reducing the physical strain associated with field testing and high-altitude operations.

②　Ultra-low partial discharge for high-precision testing

An optimized internal electric field structure combined with high-purity gas insulation ensures minimal self-generated partial discharge. During power-frequency withstand voltage tests, it effectively eliminates background noise interference, enabling the precise detection of subtle insulation defects in the test object.

③　Eco-friendly, oil-free structure; safe, explosion-proof, and environmentally conscious

The fully sealed, oil-free design completely eliminates safety hazards such as oil leaks, fires, and explosions associated with traditional equipment. It is ideal for operating environments with stringent fire safety and environmental requirements, such as underground substations and busy urban areas.

④　Fully sealed and maintenance-free with superior environmental adaptability

The unit features a high-strength sealing design that protects the internal medium from external moisture, dust, and temperature fluctuations. It delivers consistently stable performance without the need for periodic oil filtration or maintenance, ensuring reliability even in harsh outdoor weather conditions.
