Abstract
The utility model relates to a tie rod elevating seat used in a sleeve current transformer, which is characterized in that a supporting plate, a covering plate, and screw rods are comprised, wherein the supporting plate is arranged at the bottom of the transformer; the covering plate is arranged above the transformer; the tensioning screw rods are arranged between the upper covering plate and the bottom supporting plate; the three screw rods with mutual included angles of 120 degrees are distributed between the upper covering plate and the bottom supporting plate of the transformer; and the screw rods are fixed with the upper covering plate through welding, and fixed with the bottom supporting plate through nuts. Compared with the prior art, the tie rod elevating seat adopting the structure has the benefits that manufacturing cost is lowered, axial tensioning force is enhanced, and both the mechanical property and the electrical performance of the transformer in the elevating seat are improved.
Description
Technical field
The utility model relates to a kind of rod-pulling type rising seat that is used for casing current transformer, is applicable to the power transformer enclosure of band instrument transformer.
Background technology
At present, the structure of the power transformer enclosure of band instrument transformer all is the height soldering pallet on the seat inwall that raises according to instrument transformer height and two ends insulation, and it is bad that this kind structure gets axial tightening force, and mechanical performance and electric property await to strengthen.
Summary of the invention
For solving the problem that prior art exists, the purpose of this utility model provides a kind of rod-pulling type rising seat that is used for casing current transformer, and this device adopts the instrument transformer tension of screw rod with short transverse, has effectively strengthened axial force.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be used for the rod-pulling type rising seat of casing current transformer, comprise supporting plate, cover plate, screw rod, the instrument transformer bottom is provided with supporting plate, and instrument transformer top is provided with cover plate, is provided with stretching screw between top cover plate and bottom bracket.
Described screw rod is three, is mutual angle and is 120 ° to be distributed between instrument transformer top cover plate and the bottom bracket.
Described screw rod and the welding of top cover plate are fixing, and screw rod and bottom bracket are fixed by nut.
Compared with prior art, the beneficial effects of the utility model are:
By the seat top cover plate welding screw rod that raises, instrument transformer packed into to raise in the seat; Support board structure is adopted in the bottom, is provided with stretching screw between top cover plate and bottom bracket.This structure has not only reduced manufacturing cost, and is axially strengthening to some extent on the tightening force, has improved mechanical performance and the electric property of instrument transformer in the seat that raises.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Among the figure: 1-supporting plate 2-cover plate 3-screw rod 4-insulating board 5-instrument transformer 6-rising seat wall 7-instrument transformer terminals
Embodiment
See Fig. 1, be used for the rod-pulling type rising seat of casing current transformer, comprise supporting plate 1, cover plate 2, screw rod 3, instrument transformer 5 bottoms are provided with the supporting plate 1 that steel plate is made, and instrument transformer 5 tops are provided with cover plate 2, are provided with stretching screw 3 between top cover plate 2 and bottom bracket 1.Described screw rod 3 is three, is mutual angle and is 120 ° to be distributed between instrument transformer 5 top cover plates 2 and the bottom bracket 1.Screw rod 3 is fixing with 2 welding of top cover plate, and screw rod 3 and bottom bracket 1 are fixed by nut.
According to the length of the height and position of instrument transformer 5 decision screw rod 3, hold with supporting plate 1 instrument transformer 5 bottoms, fastening by nut again, between the instrument transformer with insulating board 4 intervals.This structure has not only reduced manufacturing cost, and is axially strengthening to some extent on the tightening force, has improved mechanical performance and the electric property of instrument transformer in the seat that raises.
