1. The function of the fully automatic ratio group tester
The fully automatic transformer ratio group tester is a type of power transformer testing equipment mainly used to measure parameters such as transformer ratio, group, polarity, etc. of power transformers. This equipment adopts advanced technology and design to ensure the accuracy and reliability of test results, providing strong guarantees for the safe and stable operation of the power system.
Its main characteristics are as follows:
① High degree of automation
The fully automatic ratio group tester adopts advanced microprocessor technology to achieve automation of the testing process. Users only need to set simple parameters, and the instrument can automatically complete the testing, greatly improving work efficiency.
② High testing accuracy
This device adopts high-precision voltage and current sensors, combined with advanced algorithms, to ensure the accuracy of test results. At the same time, the instrument also has a temperature compensation function, effectively avoiding the influence of temperature on the test results.
③ Rich in functions
The fully automatic transformer ratio group tester can not only measure conventional parameters such as transformer ratio and group, but also test transformer polarity, phase difference, etc., meeting the diverse testing needs of users.
④ Humanized design
This device adopts a large screen LCD display, with a user-friendly interface. Users can easily set parameters and view test results. At the same time, the instrument is also equipped with a high-speed thermal printer, which can quickly print test reports.
⑤ Safe and reliable
The fully automatic ratio group tester has comprehensive safety protection functions, such as overcurrent protection, overvoltage protection, etc., to ensure the safety of equipment and personnel during the testing process.
2. The usage method of the fully automatic ratio group tester
① Preparation before testing
Firstly, check the working status of the instrument and confirm that there are no abnormalities. Then, according to the parameters of the tested transformer, set the corresponding test parameters, such as voltage level, rated current, etc.
② Wiring method
According to the wiring method of the tested transformer, connect the voltage output terminal of the instrument to the input terminal of the transformer, and connect the current output terminal to the current measurement terminal of the transformer. Pay attention to ensuring correct and secure wiring to avoid affecting test results or causing equipment damage.
③ Start testing
After confirming that the wiring is correct, press the "Start Test" button on the instrument, and the instrument will automatically perform the test. During the testing process, the instrument will automatically record the test data and perform analysis and processing.
④ View test results
After the test is completed, the instrument will display parameters such as transformer ratio and group. Users can view or print test reports as needed. If the test results are abnormal, it should be promptly handled or professional personnel should be contacted for maintenance.
⑤ End of testing
After completing the test, first disconnect the instrument from the tested transformer, and then turn off the power to the instrument. Organize equipment and cables to ensure a clean and orderly work area.
In summary, the fully automatic transformer ratio group tester plays an important role in the power system as an efficient and accurate transformer testing equipment. Mastering its usage methods, correctly operating and maintaining equipment, is of great significance for ensuring the safe and stable operation of the power system.
According to IEC and relevant national standards, the power transformer, in the process of production, users and the maintenance test transformer variable ratio test is will do project, and it can effectively supervise the transformer products and the quality in the process of use, to prevent the transformer turn-to-turn short circuit, open circuit, connection error, regulating switch internal fault or the contact failure.To this end, the ZC-203AW full-function variable ratio tester developed and produced by our company is based on the original requirements for on-site use of users, making the operation more simple, complete, stable and reliable data, and greatly improving the speed of testing.Adapt to various large, medium and small transformer ratio test needs.ZC-203AW full function variable ratio tester is an ideal test instrument for the power industry.Unique unlimited scanning code, active data upload and other functions.The server can analyze and manage the data centrally, and export the Excel format data file, which greatly improves the detection efficiency and saves labor and time.
