Abstract
The utility model discloses an iron core insulating device which comprises a pull screw rod penetrating through a through hole in a pull plate. Clearance exists between the pull screw rod and the inner wall of the through hole. An epoxy cylinder is embedded in the clearance. The iron core insulating device has the advantages of being simple in structure and good in insulating effect.
Description
Technical field
The utility model relates to a kind of assembly of transformer, is specifically related to a kind of core inductance device.
Background technology
The original core construction of amorphous alloy transformer is for drawing screw rod directly through arm-tie, play tensioning function, the shortcoming of doing like this is: in original structure, draw screw rod directly through the through hole on arm-tie, drawing screw size is Φ 16, and the arm-tie hole is of a size of Φ 18, distance between the two is only 1mm, because drawing screw rod ground connection, so when drawing screw rod to contact, isolation effect is poor when arm-tie, insulation resistance is too low, so long-term, can make the transformer core multipoint earthing, produce eddy current and cause local overheating unshakable in one's determination, not meet the GB test requirements document of transformer.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, core inductance device that isolation effect is good.
Technical scheme: for solving the problems of the technologies described above, the core inductance device that the utility model provides comprises the screw rod that draws through through hole on arm-tie, between the described inwall that draws screw rod and through hole, has gap, in described gap, is embedded with epoxy cylinder.
As preferably, the length of described epoxy cylinder is greater than the degree of depth of described through hole.
Beneficial effect: the utility model is by embedding the structure of insulating cylinder in the gap of through hole on drawing screw rod and arm-tie, simple in structure, and has reached good isolation effect.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment
Embodiment: the core inductance device of the present embodiment comprise through through hole 2 on arm-tie 1 draw screw rod 3, draw between the inwall of screw rod 3 and through hole 2 and there is gap, be embedded with epoxy cylinder 4 in gap, the length of epoxy cylinder 4 is greater than the degree of depth of through hole 2.
In amorphous alloy core manufacturing process, this core inductance device is placed in and draws on screw rod, drawing screw rod to pass this arm-tie hole, draw screw rod, clamp unshakable in one's determinationly, guarantee that this core inductance device is put in to draw screw rod and arm-tie centre position, can effectively keep apart both, reach insulation effect, make the amorphous alloy core insulation resistance meet the GB test requirements document.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (2)
1. a core inductance device, comprise the screw rod that draws through through hole on arm-tie, it is characterized in that: have gap between the described inwall that draws screw rod and through hole, in described gap, be embedded with epoxy cylinder.
2. core inductance device according to claim 1, it is characterized in that: the length of described epoxy cylinder is greater than the degree of depth of described through hole.
