泰安干式变压器：泰安干式变压器短路试验1

泰安干式变压器短路试验1 　　
概述
根据GB6450--1986规定，短路试验是泰安干式变压器规定的特殊试验项目。该试验是在泰安干式变压器的一次侧加以额定电压.二次侧在出线端子上突然短路。在干变运行中.可能发生各种事故短路，如前所述的单相接地、两相短路以及三相短路等。
泰安干式变压器短路试验，由于其一次侧联结于容量很大的电网上，故一次侧电压维持不变.而二次侧出线端直接短路。这是泰安干式变压器运行中对其动、热稳定的典型的严苛考验，当然实际运行中.这样的三相突然短路事故是极少发生的。


Transformer short circuit test

Outline
According to the GB6450 - 1986 provides short-circuit test is a special pilot project under the dry-type power transformers. The test is in the primary side of the transformer to the rated voltage. Sudden short circuit on the secondary side of the outlet terminals. The dry change operation. Various accidents may occur short circuit, single phase, two-phase short circuit as described above, as well as three-phase short-circuit.
Dry-type power transformer short circuit test, due to its side of the links in the large capacity electric online side voltage remains unchanged. Direct short-circuit the secondary side of the outlet end. This is its dynamic operation of the dry-type transformers, thermal stability typical of the most demanding test, of course, in actual operation. Such three-phase sudden short circuit accident, little happened.
