Embodiment Construction

[0011] like figure 1 As shown, the sliding damping connection device for a substation mainly includes an inner casing 2 and an outer casing 3 connected by an arc wire 1 . One end of the arc wire 1 is fixed on the inner sleeve 2 , and the other end is fixed on the outer sleeve 3 . The arc wire 1 is an aluminum stranded wire, and the arc wire 1 and the inner sleeve 2 and the outer sleeve 3 are fixed together by welding.

[0012] In order to realize that the inner sleeve 2 can slide in the outer sleeve 3, the inner sleeve 2 is made of aluminum alloy, and its end extending into the outer sleeve 3 is sleeved with a sliding bearing 6, through which the sliding bearing 6 is in contact with its inner wall.

[0013] In order to facilitate the fixing of the tubular busbar by the outer casing 3, the outer casing 3 is made of aluminum alloy and consists of two upper and lower pieces, which are fixed as a whole by bolts and fasten the tubular busbar 8. Lubricant is applied to the inner w...

Abstract

The invention discloses a sliding type damping connection device for a transformer substation and relates to the technical field of connection of tubular buses and electrical equipment for transformer substations. The sliding type damping connection device comprises a telescopic deformable arc line, an inner casing pipe and an outer casing pipe, wherein one end of the arc line is welded on the inner casing pipe; the other end of the arc line is welded on the outer casing pipe; one end of the inner casing pipe is connected with an external equipment terminal plate; the other end of the inner casing pipe extends into the outer casing pipe and can slide in the outer casing pipe; and the outer casing pipe is used for fixing the external tubular bus. The sliding type damping connection device has the advantages that in case of earthquake, earthquake energy can be consumed by the sliding of the inner and outer casing pipes and the deformation of the arc line, so that the earthquake response of a lead is reduced, the interaction between the tubular bus and the electrical equipment is reduced and the earthquake resistance of the electrical equipment is improved.

Description

technical field [0001] The invention relates to a connecting device for a tubular busbar and electrical equipment for a substation, in particular to a sliding type busbar for a substation [0002] Damping connection. Background technique [0003] The shape of the electrical equipment in the substation is slender, the quality of the upper porcelain tube is larger than that of the lower bracket, and the equipment is connected by soft and hard wires. At the connection position between the tubular busbar and the electrical equipment, there is an inverted "U"-shaped temperature section. This temperature section has a certain expansion and contraction ability, which can adapt to the deformation of the tubular busbar due to thermal expansion and contraction, and reduce the temperature of the tubular busbar. stress. However, under the action of an earthquake, there will be a large relative displacement between the tubular busbar and the electrical equipment, far exceeding the defo...
