Three-phase or single-phase dry distribution transformer and electrical isolation method for a tap panel of a three-phase or single-phase dry distribution transformer

摘要

transformer equipped with a tap panel, electrical insulation method for a tap panel of a dry distribution transformer and tap panel for a dry distribution transformer. the present invention relates to a dry distribution transformer comprising a housing, a coil (200), a serial compartment (100) and a tap panel (110) associated with the coil (200). the tap panel (110) has an electrostatic shield (107) and is positioned inside the sealed compartment (100), the sealed compartment (100) is filled with a solid dielectric material and protected by a cover (120). Also described are an electrical insulation method for a tap panel of a dry distribution transformer and tap panel for a dry distribution transformer filled with removable insulating resin. the coil (200) having an electrostatic shield (107) grounded (115).
