专利汇可以提供Voltage stabilising arrangements专利检索，专利查询，专利分析的服务。并且A voltage stabilising arrangement for alternating current supplies in which a H.T. transmission line supplies a lower voltage feed conductor via a step-down transformer, having a saturated reactor connected to the feed conductor, a first series capacitor associated directly with the reactor for compensating the slope reactance of the reactor, and at least one other series capacitor associated with the transformer for compensating the leakage reactance of the latter, with the capacitors chosen so that together they provide slope compensation for the transmission line, each said capacitor having at least one bypass filter in parallel with it for suppressing instabilitygenerating harmonics which may be generated within the arrangement. With such an arrangement it is possible to create constant voltage levels both on the H.T. line and the feed conductor.，下面是Voltage stabilising arrangements专利的具体信息内容。

权利要求

1. A voltage stabilising arrangement for alternating current supplies, of the kind incorporating at least one saturated reactor and designed for stabilising the voltage in a high voltage transmission line having a lower voltage feed conductor connected thereto via a step-down transformer, wherein the saturated reactor is cOnnected to the feed conductor, and the arrangement incorporates a first series capacitor associated directly with the reactor for compensating the slope reactance of the reactor, at least one other series capacitor associated with the transformer for compensating the leakage reactance of the latter, with the capacitors chosen so that together they provide slope compensation for maintaining a substantially constant voltage in the transmission line, and a by-pass filter system connected in parallel with the slope compensating capacitors for suppressing instability-producing harmonics or sub-harmonics which may be generated within the arrangement.

2. A voltage stabilising arrangement according to claim 1 in which the capacitors are connected immediately in series with each other, one on each side of the feed conductor, wherein the by-pass filter system is common to and is connected across both capacitors.

3. A voltage stabilising arrangement according to claim 1 in which the transformer has a plurality of secondary windings supplying a corresponding number of lower voltage feed conductors, wherein the slope compensating capacitor associated with the transformer is provided by a number of individual components connected each in series with a respective winding of the transformer to create independent substantially constant voltage points for each of the separate lower voltage conductors as well as the transmission line.

4. A voltage stabilising arrangement according to claim 3 wherein the transformer has two secondary windings each connected to a respective lower voltage feed conductor, and the individual components comprise independent capacitors associated with the primary and one secondary winding, and a reactor associated with the other secondary winding.
