Problems solved by technology

Due to the bidding for the second phase of equipment in recent years, the bid cannot be directly renewed
In this way, during the installation of the second-phase equipment, the 10kV main busbar of the first-phase equipment is a tubular busbar, and the 10kV main busbar of the second-phase new equipment is a rectangular busbar; or the 10kV main busbar of the first-phase equipment is a rectangular busbar, and the 10kV main busbar of the second-phase new equipment The busbar is a tubular busbar, which makes it impossible to achieve effective splicing of the first-phase and second-phase equipment
In addition, the equipment inside the switchgear is not poured on the same foundation, and uneven settlement is prone to occur. When hard busbars are used to connect, the internal stress caused by uneven settlement cannot be released, and it is easy to cause the supporting porcelain bottles to bear a large internal stress. Long-term operation exists. The hidden danger of accidental tripping due to broken supporting porcelain bottles

Abstract

The invention discloses a bus connector and relates to the field of power grids. The bus connector solves the technical problem in the prior art that main buses of different types are different to connect. The bus connector comprises a plurality of layers of laminated connection sheets and two clamping parts arranged at an interval, the clamping parts clamp the connection sheets to form a middle section and joints at the two ends, the connection sheets on the joints comprise an upper connection set and a lower connection set, the Y-shaped connector is formed by the middle section, the upper connection set and the lower connection set, connection portions are arranged on the upper connection set and the lower connection set, and screws are connected between the connection portion of the upper connection set and the connection portion of the lower connection set. The bus connector is applied to an electric cabinet.

Description

【Technical field】 [0001] The invention relates to a bus bar connector, which belongs to the field of power grid components. 【Background technique】 [0002] In recent years, 10kV switchgear in 110kV substation basically adopts fully enclosed armored cabinet, and the main busbar of 10kV switchgear generally has two types: rectangular busbar and tubular busbar. When put into production, if the first-phase and second-phase equipment are put into operation at the same time, there will be no problem when the two-phase equipment is overlapped. However, in the past few years, the first phase of equipment is often put into operation, and the second phase of equipment is put into operation after a few years. Due to the bidding for the second phase of equipment in recent years, the bid cannot be directly renewed. In this way, during the installation of the second-phase equipment, the 10kV main busbar of the first-phase equipment is a tubular busbar, and the 10kV main busbar of the se...
