Basic technical requirements for installation of dry-type three-phase transformer
1.The dry-type three-phase two-winding non-exciting tap-changing distribution transformer's high-voltage down lead and high-voltage bus must adopt copper core or aluminum core rubber insulated wire.
2.The different phase to phase distance of high-voltage bus, high-voltage down lead and drop out fuse must be less than 300 mm.
3.The distance between the low-voltage side line and the high-voltage down lead shall not be less than 150 mm.
4.It is strictly prohibited that the low-voltage line passes through the high-voltage down lead, and the sag of the lead up and down lead should be neat and consistent.
5.The dry-type three-phase transformer shell, circuit breaker, arrester ground wire and transformer low-voltage side zero line should be grounded together first.
6.The dry-type three-phase two-winding distribution transformer platform should be kept horizontal and the height difference of diagonal line of the table should be less than 30mm.
