The maintenance points of relay protection tester are as follows:
1. Daily inspection and monitoring
① Running status monitoring
Regularly observe the operation status of the tester, including power supply, whether the wiring is secure, and whether the testing cables are normal.
Check the appearance of the equipment for any abnormalities, such as odor, heat, smoke, etc.
② Parameter record
Record current, voltage sampling values, and differential protection differential current values every week to ensure data accuracy.
Every month, professional personnel conduct comprehensive testing on the testing equipment, checking for faults and analyzing errors.
2. Equipment cleaning and maintenance
① Regular cleaning
Use a soft cloth to wipe the surface of the equipment, avoiding the use of chemical cleaners or direct rinsing with water.
Regularly inspect and clean the connection lines of the equipment to ensure they are not loose or damaged.
② Component maintenance
Regularly check and print the printer of the tester to prevent data loss.
Tighten the connecting components and replace aging or damaged parts.
3. Environment and Storage Management
① Operating environment
Ensure that the testing equipment operates in a dry and ventilated environment, avoiding the influence of dust, moisture, and other factors.
Avoid using in environments with strong electromagnetic fields or mechanical vibrations.
② Storage requirements
When not in use, store in a dry, ventilated, and sun free place to avoid moisture or overheating of the equipment.
4. Parameter and Function Maintenance
① Parameter calibration
Regularly calibrate the testing instrument to ensure the accuracy of the test results.
Calibration should be carried out by professionals to ensure that equipment performance meets standards.
② Functional testing
Verify whether the response and action of the tester meet expectations by simulating fault conditions such as short circuits, overloads, ground faults, etc.
Regularly check the operation status of the microcomputer protection device, such as whether the collected current and voltage data are correct.
5. Operation and record management
① Operating standards
Familiarize yourself with the operation manual before operation to ensure understanding of all function keys and operation steps.
Wear protective goggles, gloves, etc. during operation and follow safety operating procedures.
② Record management
Record the usage and maintenance of the testing instrument, including testing date, content, equipment status, and other information.
Maintaining records helps to timely understand the operation status of equipment and guide subsequent maintenance work.
6. Special maintenance and precautions
① Infrared temperature measurement
Regularly measure the terminal temperature of the infrared tester to promptly detect poor contact or heating phenomena.
② Safe operation
Turn off the power promptly after the test is completed to avoid accidents.
Avoid excessive use, reduce equipment wear and tear, and extend service life.
The ZC-702 three-phase relay protection tester comes with a large screen LCD display and a flexible and convenient rotating mouse controller. Single machine independent operation already has strong functionality and can perform most experiments, while connecting to a computer for operation has even more powerful operational capabilities. Small size and high precision. It not only has the superior performance and advanced functions of large testers, but also has the advantages of small and flexible testers, easy operation, and high reliability, with a high cost performance ratio. It is a handy tool for relay protection workers. In addition to being able to calibrate various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, it can also simulate transient, permanent, and conversion faults from single-phase to three-phase for whole group testing. It can also complete various highly automated large-scale complex verification tasks, automatically test and scan various protection settings, store test data in real time, display vector graphics, and print reports online.
