Abstract

The utility model discloses a kind of transformer core.It include: transformer core using following technical side, including iron core column, the core clamp of iron core column upper and lower side is set, it is characterized by: the core clamp is mainly formed by channel steel, " u "-shaped screw rod, without latitude band, the opposite top and bottom that iron core column is set of the channel steel, and iron core column is fixedly clamped by a pair of of screw rod at both ends；The " u "-shaped screw rod is mounted on the angle of the channel steel, and the no latitude band connection is between the " u "-shaped screw rod.

Description

A kind of transformer core

Technical field

The utility model relates to a kind of transformer cores.

Background technique

For current existing transformer noise phenomenon than more serious, transformer generates having its source in for noise: (1) iron core uses 3 grades of seam lamination techniques, seam crossing are easy to cause core vibration there is the electromagnetic attraction generated by leakage field, and leakage field draws The vibration of coil, oil tank wall is played, in addition resistance suffered by seam crossing magnetic flux increases, and equally causes vibrating noise；(2) iron core column does not have Have use without latitude band bind, transformer station high-voltage side bus for a period of time after, iron core folder is easy to produce loose phenomenon, to make lamination Between generate vibration, cause transformer noise to increase.In view of the above-mentioned problems, authorization Publication No. " 203617085 U of CN " Chinese utility model patent, open one kind " transformer core ".It is bound between its iron core using no latitude band.But there are the shortcomings that Be: tension device is set up directly on common plate, and tensile capacity is poor.

Utility model content

Stronger, the stronger transformer fe of structure that the technical problem to be solved by the present invention is to provide a kind of tensile capacity Core.

To achieve the above object, the utility model includes: using following technical side

Including iron core column, the core clamp of iron core column upper and lower side is arranged in, it is characterised in that: institute in transformer core Core clamp is stated mainly to form by channel steel, " u "-shaped screw rod, without latitude band, the channel steel it is opposite the upper of iron core column is set End and lower end, and iron core column is fixedly clamped by a pair of of screw rod at both ends；The " u "-shaped screw rod is mounted on the folder of the channel steel On angle, the no latitude band connection is between the " u "-shaped screw rod.

The transformer core, it is characterised in that: the gap between the no latitude band and iron core column is equipped with asphalt mixtures modified by epoxy resin Rouge felt pad.

The transformer core, it is characterised in that: one group of lifting lug is equipped on the channel steel of the iron core column upper end.

The transformer core, it is characterised in that: be equipped with base support on the channel steel of the iron core column lower end.

The transformer core, it is characterised in that: the screw rod both ends are respectively provided with adjusting nut.

The transformer core, it is characterised in that: the iron core column uses 7 grades of seam laminations.

The transformer core advantage of the utility model: iron core is formed by channel steel and " u "-shaped screw rod, the combination without latitude band Clamping device, overall structure is very secured, to substantially increase tensile capacity, makes to connect between iron core even closer.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawing.

As shown in Figs 1-4, a kind of transformer core of the utility model, including iron core column 1, setting are in about 1 iron core column The core clamp 2 at end.The core clamp 2 is formed by channel steel 3, " u "-shaped screw rod 4 and without latitude band 5, the channel steel 3 The opposite top and bottom that iron core column 1 is set, and iron core column 1 is fixedly clamped by a pair of of screw rod 6 at both ends.It is described " u "-shaped screw rod 4 is mounted on the angle 7 of the channel steel 3, and the no latitude band 5 is connected between the " u "-shaped screw rod 4.It is described 4 rear end of " u "-shaped screw rod is equipped with nut.The " u "-shaped screw rod 4 is installed between two cylinders of the corresponding iron core column 1 of the channel steel 3.

Further, the gap between the no latitude band 5 and iron core column 1 is equipped with epoxy resins insulation pad 8, to play absolutely Edge and make to connect even closer effect between iron core column, further prevents leakage field problem.

Further, one group of lifting lug 9 is installed on the channel steel 3 of 1 upper end of iron core column, in order to hanging for transformer core Dress.

Further, base support 10 is installed on the channel steel 3 of 1 lower end of iron core column, in order to transformer core Installation.

Further, 6 both ends of screw rod are respectively provided with adjusting nut 11, so that 6 both ends of screw rod can be adjusted, so as to In assembling.

Further, the iron core column 1 uses 7 grades of seam laminations.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., is all contained in the protection of the utility model within novel spirit and principle Within the scope of.
