The embodiment of the invention provides an on-load capacity and voltage regulating device and relates to the technical field of power supply. The device comprises a transformer and a transition switch. The transformer is loaded with a capacity regulating switch and a voltage regulating switch and comprises a primary winding. The transition switch comprises first normally-closed contacts, and the capacity regulating switch comprises second normally-closed contacts. The first normally-closed contacts and the second normally-closed contacts are connected between the primary winding and the input end of a transformer to be regulated in series, and the capacity regulating switch and the voltage regulating switch are electrically connected to the primary winding to be used for regulating the capacity and voltage, input into the transformer to be regulated, of the transformer respectively. The on-load capacity and voltage regulating device can be conveniently, rapidly and perfectly assembled with various aged transformers in operation to carry out on-site maintenance-free on-load capacity and voltage regulating transformation and upgrading on existing aged zone areas, the upgrading cost is reduced, the final barrier of promoting the capacity and voltage regulating technology is broken through, and transformation can be conveniently carried out on the energy conservation and electric energy quality improvement of transformers in the aged zones.
Description
technical field [0001] The invention relates to the technical field of power supply, in particular to an on-load capacity and voltage regulating device. Background technique [0002] At present, the mainstream energy-saving distribution transformers mainly include energy-saving oil-immersed transformers and amorphous alloy transformers. [0003] Oil-immersed distribution transformers are divided into S9, S11, and S13 capacity and voltage regulating transformer series according to loss performance. In comparison, the no-load loss of S11 series transformers is 20% lower than that of S9 series transformers, and the no-load loss of S13 series transformers is lower than that of S11 series transformers. Series 25% lower. The comprehensive no-load loss of the S11 capacity and voltage regulating transformer is 28% lower than that of the S13. The State Grid Corporation has widely used the S11 series distribution transformers, and is gradually promoting the S13 series and the S11 cap...
