Dc resistance test is transformer after the handover, overhaul and change tap-changer, indispensable test items, so use dc resistance tester for transformer dc resistance test is very important, the daily maintenance of dc resistance tester and the good operation of the dc resistance test can be run normally appear very important, Therefore, it is necessary to timely solve the problems in the application and management of DC resistance tester in practice.
(a) dc resistance tester in practice and management system is not sound
At present, many enterprises have not established a sound instrument and equipment management system, or although the relevant management system has been developed, but in the actual work, it fails to strictly follow the rules, such as instrument and equipment procurement system, borrowing and return system, operation procedures, maintenance system, accident handling methods, etc.. When purchasing equipment, they do not strictly follow the procedures of laws and regulations, and the functions of instruments and equipment do not match the actual needs, resulting in unnecessary waste of resources; Purchase without long-term planning, blind procurement, resulting in discontinuous equipment; In the process of using the equipment, there is no regular inspection and verification of the equipment, resulting in the loss of equipment and control. In a word, the test equipment in the planning, procurement, acceptance, management and other links are not perfect and unsatisfactory place.
(2) Dc resistance tester in practice and management of accounts and physical management
Non-standard enterprises to increase the amount of equipment and equipment, more types, therefore, equipment accounts variety miscellaneous, heavy registration work. Most of the enterprise test equipment accounts in the accounting department set up accounting details, and the accounting department pays more attention to the value of equipment accounting, ignore and test equipment management department often check the amount and value of assets; The test equipment management department pays more attention to the approval, acceptance and other general work of the equipment, and ignores the regular inspection, check and injection elimination and other daily management work of the equipment, resulting in the imperfect establishment of equipment ledger, inaccurate name, equipment is not labeled, unauthorized appropriation, lending without registration and other phenomena. In this way, the accounting department and the test equipment management department will be inconsistent with the accounts at the end of the year.
(3) Partial aging of test instruments and equipment
With the passage of time, some components of the equipment will produce aging, damage, equipment performance decline, energy consumption increase. If the test equipment is not maintained or updated in time, it will be difficult to ensure the accuracy of test data and seriously affect the quality of test data results.
(4) The quality of test equipment management personnel is low
Many enterprises engaged in the operation and management of instruments and equipment personnel in the knowledge structure can not adapt to the development of modern test requirements. Such as some large precision equipment or imported equipment replacement fast, complex performance, many test equipment personnel do not have the relevant knowledge and skills, the use of equipment is not in place, resulting in a lot of tests involving new knowledge and new technology can not be carried out normally, affecting the research and development of new technology; In addition, the laboratory management personnel lack the knowledge of equipment maintenance, in daily life or after the test, there is no maintenance of the DC resistance tester, resulting in the normal use of equipment, seriously affecting the normal test.
