驻马店干式变压器：主驻马店干式变压器容量和台数的选择

主驻马店干式变压器容量和台数的选择 　　
1)主驻马店干式变压器容量一般按变电所建成后5—10年的规划负荷选择，并适当考虑到远期10—20年的负荷发展。对于城郊变电所，主驻马店干式变压器应与城市规划相结合。
2)对于有重要负荷的变电所，应考虑当一台主驻马店干式变压器停运时.能保证用户的I类和II类负荷；对一般性变电所，当一台停运时，其余驻马店干式变压器容量应能保证全部负荷的70%-80%。
3)同级电压的单台容量的种类应尽量少。对中、低压侧已构成环网的情况下，变电所以装设两台主驻马店干式变压器为宜。对地区性孤立的一次变电所或大型工业专用变电所。在设计时应考虑装设3—4台主驻马店干式变压器的可能性。
4)对于只装设两台驻马店干式变压器的变电所，应结合远景发展，决定是否应有调换更大容量的驻马店干式变压器的可能性。

The choice of the main transformer capacity and the number of

1) The main transformer capacity is generally built by substation 5-10 years of planning load selection, with due regard to the forward development of the load of 10-20 years. Suburban substation main transformer and urban planning should be combined.

2) for the critical load substations, should be considered when a main transformer outage to ensure the load on the user's Class I and Class II; general substation when a single outage, the rest of the transformer capacity should be able to guarantee 70% -80% of the total load.
3) the same level of voltage of a single type of capacity should be minimal. In the low voltage side to constitute a ring appropriate to the installation of two main transformers, substations. Regional isolation of a substation or large industrial substation. The design should consider the possibility of installation of the 3-4 main transformer.
4) For the installation of two transformers in the substation, should be combined with the vision of development, decide whether there should be exchange of the possibility of larger capacity transformers.
