Description

technical field [0001] The invention relates to the technical field of terminal auxiliary connection, in particular to an auxiliary device for connecting secondary equipment to bus voltage without power failure. Background technique [0002] When transforming the secondary voltage circuit of the busbar in the substation, it is necessary to connect the secondary voltage circuit of the busbar of the new parallel device to protection, measurement and control, safety, metering and other devices. At present, the secondary voltage circuits of busbars are very complicated, mainly reflected in the large differences in the access methods of the secondary voltage circuits used. Generally, there are the following three circuits: a) directly from the parallel device; b) from the top of the screen Small busbar; c) parallel connection with busbar voltage of other screen cabinets. At the same time, the above three methods are generally used crosswise, which intensifies the complexity of th...
