Key Features & Advantages
1. High Efficiency:
The "triple-cup" design is the primary advantage. While one cell is being tested, the operator can prepare the next sample or handle other tasks. The oil dielectric strength test device supplier automatically cycles through the three cells, significantly increasing sample throughput, especially for high-volume testing.
2. Full Automation:
Automatic cell switching, stirring, voltage ramping, breakdown detection, discharging, result calculation, and report generation are all integrated into the system.
This greatly reduces manual operations and human error.
The operator only needs to inject samples, start the test, and retrieve results, resulting in low labor intensity.
3. High Accuracy & Repeatability:
The system utilizes precision high-voltage generators and high-sensitivity detection circuits.
It strictly adheres to test conditions specified by international standards, including electrode shape, gap distance, and voltage ramp rate.
The automated process eliminates manual inconsistencies, ensuring reliable and repeatable results.
4. High Safety:
Multiple safety protections are integrated, including a test chamber door interlock, emergency stop button, overcurrent protection, and grounding protection, ensuring operator safety.
Testing is performed within a closed or semi-closed chamber, minimizing exposure to high voltage.
5. Multi-Functionality (Common):
The oil dielectric strength test device is compatible with multiple international standards.
Configurable parameters include stirring/resting time, voltage ramp rate, number of tests, and more.
Advanced models may integrate oil temperature measurement/control or micro-water testing (requiring additional sensors).
It also features robust data storage and management, including historical data storage and report export functions.
6. User-Friendly:
A large LCD or touchscreen display provides intuitive menu operation and supports a multi-language interface (e.g., Chinese/English).
Test status and results are displayed in real time.
The oil dielectric strength test device also includes self-diagnostic fault prompts.
Application Scenarios
The oil dielectric strength test device manufactures is an essential tool for assessing the quality of insulating oil across the power industry:
Power Utilities and Substations: Used for routine preventive testing of transformer oil, circuit breaker oil, and other insulating fluids to ensure the reliability of in-service equipment. The three-cup design is particularly useful for testing multiple samples during maintenance outages.
Transformer and Electrical Equipment Manufacturers: Used for quality control and factory acceptance testing of new insulating oil before it is filled into equipment, especially for high-volume production lines.
Independent Testing Laboratories: Used by third-party labs to perform oil quality analysis for clients, where batch testing capability is essential.
Maintenance and Repair Facilities: Used to test oil during maintenance, retrofilling, or oil reclamation processes.
FAQ
1,What is the purpose of the Transformer Oil BDV Tester?
The purpose is to measure the breakdown voltage of insulating oil, which is a key indicator of its dielectric strength. low breakdown voltage can indicate contamination, moisture, or degradation of the oil, which can compromise the insulation of power equipment.
2. How does the instrument ensure accurate results?
Accuracy is ensured through the use of a microcomputer control system, a watchdog circuit for stability, and a unique high-voltage sampling design that feeds test values directly into the A/D converter, minimizing errors from analog circuitry. The sturdy, leak-proof glass oil cups also help prevent measurement interference.
3. What are the physical specifications and is it portable?
The oil dielectric strength test device factory is designed to be portable, with dimensions of 670mm×420mm×410mm and a weight of 38kg. This makes it suitable for transportation between laboratory and field test sites, although the three-cup design is somewhat larger than single-cup models.
