Guizhou electric equipment company mentioned that in the stage of using power resources and power system, we should pay full attention to the maintenance of power electrical equipment in the system, and further ensure the long-term operation of the power system to the maximum extent. But for the maintenance of electrical equipment, it will involve a lot of professional technology, and the high-voltage test of electrical equipment needs professional personnel to operate. Therefore, the high voltage test of electrical equipment is particularly critical.

1. Test of high voltage maintenance equipment

1.1 problems in maintenance test technology of high voltage electrical equipment

The first is the grounding problem, which is the most common problem in the maintenance test of high-voltage electrical equipment, especially the capacitor maintenance test. In general, the grounding problem can be divided into two categories: filter grounding problem and test equipment grounding problem.

The second is the lightning rod lead problem. In the stage of high-voltage electrical equipment maintenance test, when the resistance of the lightning protection device in the power grid is too high or the lightning arrester is disconnected, the maintenance and test personnel mistakenly cut the lead wire of the lightning arrester, and then lead to leakage problems in the power system, which directly affects the safety, reliability and reliability of the electrical equipment maintenance test Accuracy.

Finally, the test measurement results are not accurate enough. In the specific implementation of high-voltage power equipment maintenance test stage, the measurement results are not accurate enough, of course, this is also a frequent problem. Test methods, personnel, site environment and so on will affect the final results. The most important factor in the measurement experiment is human factors.

1.2 causes of maintenance test problems of high voltage electrical equipment

First of all, the attitude of maintenance test staff is not rigorous. That is to say, in the stage of equipment maintenance test, the importance of maintenance test work is low, then the implementation of comprehensive and meticulous observation for high-voltage electrical equipment will directly ignore the safety risks of high-voltage equipment, which will also reduce the hidden safety problems of high-voltage equipment, and thus reduce the accuracy of maintenance test Secondly, there is a lack of sound and reasonable maintenance test and system.

2. Improvement measures for maintenance test of high voltage electrical equipment

2.1 establish a comprehensive and perfect test plan

In the specific implementation of high-voltage electrical equipment maintenance test is the fundamental premise of the plan, so a comprehensive and sound program technology is particularly critical. In the initial formulation of the program, we can analyze and study the problems in the current working mode in advance, and summarize the experience. It is worth noting that it is necessary to continuously promote the professional technology and literacy of test technicians themselves, and further strengthen the technical assessment of design and maintenance test planners fundamentally.

2.2 implement strict maintenance system of high voltage electrical equipment

In the process of maintenance and test of high-voltage electrical equipment, a sound maintenance system is indispensable. The maintenance should timely transmit data to the corresponding monitoring system, and use scientific and reasonable management system to implement step by step, so as to better judge the operation of high-voltage equipment. The construction of high-voltage electrical equipment maintenance system mainly starts from two aspects, namely management system and diagnosis system. There is a large amount of information contained in high-voltage electrical equipment, so each static and dynamic information must be stored in time.

2.3 ensure the accuracy of test instruments

For the accuracy of maintenance test equipment, it will directly affect the final test results, and equipment failure will occur in serious cases. Therefore, the equipment and instruments used for high-voltage test should meet the corresponding standards. The test instruments must be tested by professional institutions and can only be used after reaching the standard.

3. Conclusion

Guizhou electrical equipment company in order to ensure that high-voltage electrical equipment is always in a normal operation state, the role of high-voltage electrical equipment maintenance test work is particularly critical, so strengthening the ability of maintenance test is the mainstream trend. Therefore, under the situation of paying attention to the maintenance test problems, we should carry out effective treatment from the professional level, further strengthen the professional ability of technical personnel, and fundamentally improve the quality of maintenance test.
