Insulating sleeve maintenance personnel need to master the technology which Repair and maintenance personnel should pay attention to the following questions: Testing personnel disconnect the end of the insulating sleeve small screen casing lead , should prevent the guide rod rotate or twist off the ground lead , after the test should be restitution.

According to experience , the test can be used after the end of the end of the multimeter to measure the screen is grounded, check the end of the screen which is removed after the ground has been restored to a more reliable way ; take oil samples personnel operating junction , should tighten the sampling valve ; disconnect lead personnel should pay attention to prevent the upper and lower casing insulating sleeve breakage ; maintenance personnel should observe the oil level and timely casing up the oil .

Insulating sleeve bushing maintenance personnel should be familiar with the technical performance, such as the main casing factory pilot projects have dielectric loss measurement , partial discharge measurements , frequency voltage withstand test , tightness test, as well as the appearance and size detection.

Also familiar with casing conditions of use, such as the casing installed ambient temperature of -40 ~ +40 ℃, in the transformer between the axis perpendicular to the mounting angle of not more than 30 ° and so on. Repair and maintenance personnel should also be done: use every opportunity to carefully check the power tube, eliminating defects in a timely manner , carbon seamless steel pipe manufacturer china eliminate hidden dangers ; strict quality control, repair and maintenance of purchased materials are inspected and accepted by the parties concerned ; continuously improve their professional skills, ensure the quality of maintenance . In addition, repair and maintenance personnel should be familiar with the technical requirements of casing . First, be familiar with the technical performance of the casing , such as casing factory mainly pilot projects have dielectric loss measurement , partial discharge measurements , frequency voltage withstand test , tightness test, as well as the appearance and size detection.

Second, we must be familiar casing conditions of use, such as the casing installed ambient temperature of -40 ~ +40 ℃, in the transformer between the axis perpendicular to the mounting angle of not more than 30 ° and so on.
