In the field of high-voltage equipment insulation withstand voltage and partial discharge testing, "difficult transportation, slow installation, and significant partial discharge interference" have long plagued power construction and O&M units. Statistics show that 85% of power companies face issues with low efficiency in on-site high-voltage testing and time-consuming equipment deployment. Traditional testing equipment requires an average of 6 hours for wiring and debugging, while in emergency repairs for sudden failures, every hour of delay results in losses exceeding 100,000 yuan. The introduction of the Vehicle-Mounted Partial Discharge Variable-Frequency Series Resonance Test System provides a systematic solution to this industry pain point.
Core Selling Point 1: All-in-One Vehicle, Deployed in 10 Minutes
Traditional equipment requires separate transportation and on-site assembly, taking over 4 hours-a process that is even more challenging during emergency repairs in mountainous areas. This product features a fully integrated design that combines the power supply, resonant reactor, and control system into a single vehicle, consolidating the entire testing system onto one unit. Equipped with an automatic deployment testing platform, it eliminates the need for on-site hoisting and can be fully deployed and ready for testing within 10 minutes of arrival. The main circuit conductors are permanently connected, eliminating the need for repeated wiring and significantly reducing on-site workload.
Key Selling Point 2: Ultra-Low Partial Discharge, Precise and Reliable Detection
The system features a fully shielded, partial-discharge-free design, with partial discharge strictly controlled below 10 pC. Voltage fluctuations are ≤1%, enabling precise identification of insulation defects and reducing the false positive rate to below 2%. Equipped with real-time monitoring for overvoltage, flashover, and leakage, the system triggers an emergency stop within 0.1 seconds to ensure testing safety.
Key Selling Point 3: 30–300 Hz Intelligent Frequency Conversion, High Efficiency and Energy Savings
The system's output frequency range is continuously adjustable from 30 Hz to 300 Hz, automatically adapting to the capacitive characteristics of the equipment. Energy consumption is only one-third that of traditional power-frequency testing. Frequency instability is ≤0.05%, meeting the on-site insulation withstand voltage testing requirements for high-capacitance equipment such as GIS, power cables, and large generators.
Core Selling Point 4: All-Scenario Adaptability and Professional After-Sales Support
The system operates seamlessly in environments ranging from extreme cold (-20°C) to high temperatures (50°C), ensuring trouble-free operation in harsh conditions such as mountainous regions and oil fields. Vehicles are customized to meet client requirements and support remote expert consultation and cloud-based data management. We offer a 3-year warranty, lifetime maintenance, free software upgrades, and telephone guidance within 15 minutes.
