Problems solved by technology

[0003] The purpose of this invention is to solve the problem that each group of reactive power compensation devices will occupy a 10KV power distribution interval, and the number of devices is not many but the capacity is large due to the limitation of substation intervals. To solve the problem of undercompensation, provide a capacitor and series reactor synchronous capacity adjustment and reactance switch

Embodiment Construction

[0013] As shown in FIGS. 1-2 , the capacitor and series reactor synchronous capacity and reactance adjustment switch is composed of an insulating cylinder 15 , a moving contact 16 , a static contact 14 , a rotating shaft 17 , and a motor mechanism 13 . Said electric mechanism 13 is located at the top of the insulating cylinder 15, and the rotating shaft 17 is located at the center of the insulating cylinder 15 and is connected with the electric mechanism 13. On the rotating shaft 17, a moving contact 16 is arranged corresponding to the insulating cylinder 15, and a static contact 14 is provided. On the insulating cylinder 15, the moving contacts 16 and the static contacts 14 are longitudinally arranged in three layers, and each layer of static contacts 14 is twelve and fixed on the insulating cylinder 15 symmetrically and equally. The sequence in the clockwise direction is the first static contact terminal 1 to the twelfth static contact terminal 12, of which the tenth, elevent...

Abstract

The present invention relates to a capacitor and series-connected reactor synchronous capacitance-regulating reactance-regulating switch. It is composed of insulating cylinder, moving contacts, static contacts, rotating shaft and electric mechanism. Said invention also provides their connection mode and concrete arrangement structure. Said invention has good continuous capacitance-regulating and reactance-regulating property, can be extensively used in 10KV reactive-load compensation equipment of transforming station, and can raise the accuracy of reactive-load compensation equipment of transforming station.

Description

technical field [0001] The invention belongs to electric power equipment used in the technical field of reactive power compensation in electric power systems, and in particular relates to a synchronous capacity and reactance adjustment switch for capacitors and series reactors. Background technique [0002] At present, because the power system does not have a switch for synchronous adjustment of capacitors and series reactors, the reactive power compensation devices of the substation are all controlled by the whole group. The biggest drawback is that each group of reactive power compensation devices occupies a 10KV power distribution interval, and the number of devices is limited by the interval of the substation, but the capacity is large. On-site frequent occurrence of over-compensation when switching on, and under-compensation if not switching. The problem of compensation makes the installed reactive power compensation device unable to fully play its role and affects the ...
