Dry-type transformer is an important transformer and an important power equipment. The distance of the dry transformer is an important core issue, which is also the operation of the dry transformer, and the distance of the dry transformer should be paid attention to the correct installation. So how is the distance of the common dry transformer, especially the location of the distance wall, regulated? Or to carry out detailed communication and exchange with the small edition of the dry transformer factory:

Dry-type transformer is generally installed in a fully enclosed metal box, the distance between the outer wall of the dry-type transformer and the metal box to meet the safety distance, no discharge can be, and the distance between the metal box and the wall to meet the requirements of passage, maintenance and operation can be; Generally, the maintenance channel is 800mm wide, and the operation channel is 1500mm wide. Generally, the inlet line of dry transformer adopts cable or closed bus, the outlet line adopts closed bus, and the long distance can be used in the form of bus bridge.

Condition maintenance is based on the diagnostic technology of electrical equipment. Various measuring means are used to detect whether there is any abnormality in the transformer. More accurate diagnostic results are obtained through diagnostic analysis, and then maintenance plans are arranged according to the harm degree of the results. It can be seen that the reliability of diagnostic technology and the accuracy of diagnostic results are the key issues to achieve the desired goal. It is not comprehensive to simply establish the basis of transformer condition maintenance on the basis of online monitoring, and can not completely rely on online monitoring equipment, which should be combined with online monitoring equipment and preventive testing to achieve comprehensive analysis and diagnosis.

At present, there are no uniform rules, norms and guidelines for the condition maintenance of high voltage electrical equipment in China. The condition analysis of transformer is the basis of condition maintenance management. The status of the transformer is mainly analyzed according to the transformer factory test and acceptance records, daily operation records and the results of various tests and tests. Specifically, the transformer factory test and acceptance records should include the factory tests stipulated in the order agreement, the record of the conclusion of the transformer supervision, and the daily operation records of the transformer, mainly including the top oil temperature, ambient temperature, load condition during operation over the years, whether it is hit by lightning, whether there is abnormal sound vibration, whether it is hit by external short circuit shock and other detailed records. The results of various tests include the results of preventive tests, specific tests and online monitoring over the years. In addition, for the overhauled transformer, the records of the overhaul should also be used as the basis for analysis.

The above is the introduction of the distance from the wall of the common dry transformer for your reference, for the distance of the dry transformer you still have any questions, please login to our website to understand it!
