1LJC voltage breakdown testerProduct Usage and Overview:
Mainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as resins and adhesives, impregnated fiber products, mica and its products, plastic composite products, ceramics and glass under power frequency voltage or DC voltage; This instrument is computer-controlled and can quickly and accurately collect, process, access, display, and print various data during the experimental process.
LJC voltage breakdown testerIt is an important instrument for testing the voltage breakdown strength of products. By relying on the simulation test conditions provided by this instrument, various tests such as breakdown voltage and leakage current can be conducted intuitively, accurately, quickly, and reliably on various tested objects. The instrument adopts dual control of touch screen and computer, which can conveniently store, process, display and print the test results. After years of continuous improvement and refinement, this instrument has become increasingly mature, with high safety and reliability, and has received high praise from users.
2、 According to the standard:
The instrument is manufactured according to the requirements for breakdown voltage in the following standards;
1. GB1408.1-2006 "Test Methods for Electrical Strength of Insulation Materials";
2. GB1408.2-2006 "Test Methods for Electrical Strength of Insulation Materials Part 2: Additional Requirements for Application of DC Voltage Test";
3. GB/T1695-2005 "Determination method for power frequency breakdown voltage strength and withstand voltage of vulcanized rubber";
4. ASTM D149 "Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulation Materials at Industrial Power Supply Frequency";
5. GB/T3333: Test method for power frequency voltage breakdown of cable paper;
6. GB/T12656: Test method for power frequency voltage breakdown of capacitor paper;
7. HG/T3330: Determination of breakdown strength of insulation paint film .
3、 Instrument function:
1. During the experiment, the experimental curve can be dynamically drawn, and the experimental curve can be overlaid with multiple colors for comparison;
2. Can edit and modify experimental data, flexible and applicable;
3. The experimental conditions and test results can be automatically stored;
4. The format of the test report is flexible and adaptable to meet the different needs of different users;
5. The validity of curve data in a set of experiments can be manually selected;
6. The experimental result data can be imported into Excel and edited in WORD documents;
7. The overcurrent protection device has sufficient sensitivity to ensure that the power is cut off within 0.1 seconds when the sample breaks down;
8. The durability of instrument operation allows for continuous use without the need for periodic shutdowns to protect the instrument. .
4、 InstrumentFeatures:
1. Independent control system, modular structure for easy after-sales maintenance, beautiful and atmospheric appearance, no noise during the entire experimental process, automatic centering and positioning of the electrical level, easy operation, high safety factor, and high accuracy.
2. The operation and control are carried out by the touch screen and control panel of the device itself. If curve analysis is not required, a computer is not required.
3. If curve analysis is required, a computer can be equipped to only perform data and curve recording functions without equipment control, avoiding the need for testers to alternate between the computer and equipment, making it more user-friendly.
4. The equipment has a test parameter memory function, which does not require setting for each test under the same test conditions, and the last test setting parameters will still be remembered when the power is turned off.
5. The experimental interface is simple and clear, with explanatory curves. Different parameters result in different curve trends, making it easy to understand.
6. The control panel is simple, with clear functional labeling and easy operation.
7. It can record and display 10 test records simultaneously, facilitating comparative analysis of test data. And any set of data that is not ideal can be discarded at any time.
8. Added USB download function, which can directly download test records from the device to the USB drive.
9. If equipped with a computer, detailed test reports can be generated, including specific information for each group, comprehensive information for multiple groups, and curves.
10. The equipment testing interface adopts a dashboard and real-time display of numbers, which is more convenient for viewing the testing process.
11. The equipment has a safety warning prompt. The test cannot start without closing the test chamber door, and a warning will pop up. When it is at full capacity (i.e. no output from the high-voltage transformer), a warning will pop up. If the door is opened during the test, the test will automatically end.
12. Using Bluetooth data transmission to solve the trouble of wall blocking and long-distance operation safety and reliability;
13. The equipment is equipped with a three color alarm light. When the green light is on, it indicates that the box door is well closed and the test can begin. When the yellow light is on, it indicates that the test box door is open and the sample can be replaced. When the red light is on, it indicates that the high voltage is greater than 0.5KV. Do not open the door at this time. The warning light will flash and sound an alarm during the discharge process after the DC test is completed. (Summary: The green light box door is closed well, the yellow light is opened with caution, and the red light has high voltage)
4、 Instrument advantages:
