Standard series reactor

Series reactor
JB instead of JB 5346-5346. 5346-1998

Before the speech
This standard is according to the ministry of machine building planning revision of the standard system, in 1997, 97462002, the revised standard JB 5346-5346.
The writing of this international standard format according to the GB/T l. 1-1993 standard reorganized.
The content of the major revision of this standard are as follows:
Project 1) revised rated reactance rate by 4.8%, 6%, 12%, (13%) to 4.5%, 5%, 6%, 12%, 6%.
2) according to the requirements of form a complete set of shunt capacitance rated voltage increases the reactor of the rated voltage, and related parameters.
3) the original standard stipulated in the R10 series number system capacity of capacitor set, then rated export reactor reactance rate capacity series, purpose is to factory with as little as possible capacity to meet the requirements as much as possible the user specifications varieties.But due to the capacity of capacitor set and capacitor unit series spectrum standard is not consistent, have trouble matching combination.But even so, also cant satisfy the user needs in a wide range of specifications, so cancelled this revision in the original standard table 2 and table 3, no longer regulation capacity of the series of specifications.
4) due to cancel capacity series of specifications, also cant again to form its loss values to each kind of capacity regulation.This revision is cancelled in the original standard table 6 (A), 6, 7, 7 (A) (B) (B), 8, 8 (A) (B), loss value calculation formula is given and the loss factor.
5) reactance value allow deviation from 0 ~ 15% to 0 + 10%.
6) insulation level in line with GB 311 standard.The oil-immersed core type reactor insulation level and oil-immersed power transformer are the same, dry-type air-core reactor insulation level and busbar post insulator are the same.
7) increased use a bridge to measure reactance value content.
8) has been cancelled for outdoor type hollow reactor in heavy rain condition of winding turn-to-turn insulation test requirements.
9) to delete the clause steady-state overvoltage.Because of stable current regulation conditions, including the requirement for steady-state overvoltage, actually.
