22、ect of this standard is to specify the cut-out in the cover or tank wall and details of the insulator and its mounting to ensure interchangeability of busbar insulators for rated voltages up to 1 000 V and rated currents from 1 250 A up to 5 000 A for insulating liquid filled transformers. 1 Scope T
23、his standard is applicable to moulded indoor busbar bushings for rated voltages up to 1 000 V, rated currents from 1 250 A up to 5 000 A and frequencies from 15 Hz up to 60 Hz for insulating liquid filled transformers. NOTEThese bushings are suitable for operation at 1,1 kV in compliance with HD 428
24、.1 S1. 2 Definitions For the purposes of this standard, the following definition applies: 2.1 moulded indoor busbar bushing a bushing in which the insulation consists of moulded organic material with a single conductor 3 Requirements 3.1 Application Busbar bushings covered by this standard shall be
25、suitable for operation under the following conditions: with both ends fully immersed in an insulating liquid; one end fully or partially immersed in an insulating liquid and with the other end in air (indoor environment); both ends in air (indoor environment) for special applications. 3.2 Standard v
26、alue of rated voltage (Ur) The rated voltage Ur is 1 000 V (phase to phase). 3.3 Standard values of rated current (Ir) The values of Ir shall be chosen from the standard values as given below, in amperes: 1 250 1 600 2 000 2 500 3 150 4 000 5 000 3.4 Minimum nominal creepage distance The minimum nom
27、inal creepage distance for bushing ends intended for use in air is 55 mm. 3.5 Dielectric characteristics 3.6 Dimensions The dimensions shall be as specified in Figure 1 and Table 1. The lengths of busbars and terminations are not covered by this standard. Power-frequency withstand voltage (60 s):dry
