Abstract

The invention provides a synchronous on-off auxiliary device for an auxiliary switch of a transformer substation. The synchronous on-off auxiliary device comprises a first connecting disc, a second connecting disc, a transmission mechanism, a device shell and a mounting bottom plate, wherein a transmission mechanism is arranged in the device shell, one end of the transmission mechanism extends outof the upper side surface of the device shell, one end of the transmission mechanism is connected with the first connecting disc, the other end of the transmission mechanism extends out of the lowerside surface of the device shell and is connected with the second connecting disc, and one side surface of the device shell is connected with the mounting bottom plate. According to the invention, theauxiliary switch, the disconnecting link or the grounding switch connected with the first connecting disc and the second connecting disc respectively is subjected to angle adjustment and cooperativerotation by adopting the transmission mechanism, so that the synchronous operation of the auxiliary switch and the power equipment is realized, and the electrical error control caused by premature opening of a locking loop is avoided.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for electric power equipment, and more specifically, relates to an auxiliary device for synchronous opening and closing of auxiliary switches in substations. Background technique [0002] At present, the rotation angle of the auxiliary switch used in the substation is inconsistent with the rotation angle of the power equipment used in conjunction with it. When the position of the power equipment is not in place, when the auxiliary switch has completed switching, it will cause premature opening of the locking circuit and lead to electrical miscontrol. , easily lead to safety accidents. Contents of the invention [0003] The present invention provides an auxiliary device for synchronous opening and closing of auxiliary switches in substations in order to overcome the defect that the inconsistency between the auxiliary switch and the electric equipment rotation angle described in the prio...
