Dielectrímetro para aceite aislante YDJ

DCde alta tensiónportátil

Product Introduction
The YDJ Pointer 5kVA Oil-Immersed AC Test Transformer is a traditional high-voltage testing device that utilizes oil insulation to deliver stable AC withstand voltage tests on electrical equipment. With a 5kVA capacity, it is well-suited for testing medium-sized apparatus such as transformers and cables. The pointer-style analog interface provides clear, real-time readings of voltage and current. The oil-immersed design ensures effective heat dissipation and reliable insulation performance, making this classic tester an ideal choice for industrial and laboratory applications that demand robust dielectric strength validation.

Product Characteristics

• Superior Material & Reliable Quality – The high-voltage test transformer features carefully selected materials, ensuring reliable quality and excellent operational stability.
• High Voltage Margin & Low Partial Discharge – Designed with a large voltage margin, a compact corona ring, and minimal partial discharge levels for enhanced performance.
• Compact & Lightweight Design – Utilizes advanced new insulation materials, resulting in a smaller footprint and lighter weight for improved portability.

Main application scenarios

• Power system testing: used to test transformers, switchgear, relays, and transmission lines by applying high voltage/high current to detect performance under load and overload conditions.
• Insulation material testing: performs voltage withstand tests on insulation materials (cables, insulators, transformer windings, etc.) to verify reliability and safety under working conditions.
• Voltage withstand test: partial discharge and leakage current tests to evaluate insulation level and compliance with safety standards.
• Fault simulation testing: short circuit testing, overvoltage testing, and frequency response testing to check stability and protection performance under fault conditions.
• Electronic device testing: evaluate components or circuits in liquid media to ensure reliability and durability under immersion conditions.
• Mechanical engineering applications: simulate wear and friction in lubricating or hydraulic oil environments to evaluate performance and lifespan.
• Materials science research: closed-environment testing for corrosion resistance or high-temperature resistance of materials.
• Automotive industry applications: evaluate components that must withstand lubricating oil or preservative environments.
• Medical equipment testing: simulate physiological-fluid-like conditions to evaluate compatibility and safety performance.

Frequently Asked Questions (excerpt)

• Before operation: the shell and iron core must be grounded at one point; grounding resistance should not exceed 0.5 Ω. Check insulation oil level to avoid exposed high-voltage lead.
• If voltage cannot rise although regulator is at maximum: possible reasons include large supply line voltage drop, severe insulation breakdown (short circuit/leakage), or poor contact of carbon brush/broken winding of voltage regulator.
