3 Replaces JB5346-91
This standard is based on the 1997 standard preparation and revision plan No. 97462002 of the Ministry of Machinery Industry, and the format of the cost standard is reorganized according to the GB/TI.1-1993 standard. The main revisions to this standard are as follows:
1) The rated reactance rate item has been modified, from the original 4.8%, 6%, 12%, (13%) items to 4.5%, 5%, 6%, 12%, 13%2) The rated terminal voltage of the reactor and its related parameter requirements are added according to the rated voltage requirements of the matching parallel capacitor. 3) The original standard specifies the capacitor bank capacity according to the R10 series number system, and then derives the reactor capacity series according to the rated reactance rate. The purpose is to allow manufacturers to meet as many user specifications as possible with as little capacity as possible. However, since the capacity of the capacitor bank and the series spectrum standard of the capacitor unit are not completely consistent, there are difficulties in matching and combining. Even so, it still cannot meet the needs of users with a variety of specifications. Therefore, this revision cancels Table 2 and Table 3 in the original standard and no longer specifies the series specifications of capacity.
4) Due to the cancellation of the series specifications of capacity, it is no longer possible to specify the loss standard value for each capacity in a table form. This revision cancels Tables 6(A), 6(B), 7(A), 7(B), 8(A), and 8(B) in the original standard, gives the loss value calculation formula and specifies the loss coefficient. 5) The allowable deviation of the reactance value is changed from 0~15% to 0+10%. 6) The insulation level is consistent with the GB311 standard, that is, the insulation level of the oil-immersed iron core reactor is the same as that of the oil-immersed power transformer, and the insulation level of the dry-type air-core reactor is the same as that of the busbar support insulator. 7) The content of measuring the reactance value by the bridge method is added. 8) The requirement for conducting the inter-turn insulation test of the outdoor air-core reactor under rain conditions is cancelled. 9) Cancel the steady-state overvoltage clause. Because the conditions for steady overcurrent actually include the requirements for steady-state overvoltage.
