Abstract
The utility model discloses a positioning structure of epoxy resin pouring current transformer low tension winding, which comprises an n-shaped dished hold frame (3), a rectangular supporting plate (5), a low tension winding (1), and an epoxy glass and fabric swatch pad (7). The bottom of the hold frame (3) is bent inwards 90 degrees, with the through-hole on the bending surface. The supporting plate (5) has two counterbore strip holes with through-hole in both ends. The bending surface of the hold frame (3) is fixed on the low tension winding (1), and the bending surface is fixed on the supporting plate (5), which is arranged on the bottom of the pouring body with the epoxy glass and fabric swatch pad (7). The positioning structure of current transformer low tension winding can guarantee that enough insulating space is reserved between the low tension winding (1) and the high tension winding (2); therefore, the positioning structure has the advantages of stable fix, convenient and high efficient assembling.
Description
Technical field
The utility model relates to a kind of current transformer, and is special relevant with the location structure of poured with epoxy resin current transformer mesolow coil.
Background technology
Current transformer mainly is a kind of transformer that transmits information to measuring instrument, instrument or protective device.Current transformer is in operation and bears the electric power system operating voltage for a long time, therefore will guarantee between low-voltage coil and the high-tension coil enough insulating spaces to be arranged, and is quite high to the low-voltage coil positioning requirements.
The Current Transformer Secondary coil location of existing poured with epoxy resin moulding is the cushion block that waters by the raw material of jumping a queue between high-tension coil and the low-voltage coil with casting transformer, utilize the cushion block adjustment to guarantee insulating space between low-voltage coil and the high-tension coil, use the poured with epoxy resin moulding then.This structure coil location in assembling process is not firm, and is easily loosening, causes the hub of a spool skew, not in the seat, makes non-uniform electric, and it is unreliable to cause easily insulating, even punctures.The structure of cushion block adjustment is not easy to assembling, and efficient is low.
Summary of the invention
The purpose of this utility model is that design is a kind of can secure fixation, is convenient to assembling, the poured with epoxy resin current transformer low-voltage coil location structure that production efficiency is high.
The technical solution of the utility model is: the n bracing frame of an inner concavity is set, and end portion inwardly is bent into 90 degree faces, and through hole is arranged on the folding surface; Other has a rectangle support plate, and two rectangular through holes of counterbore shape are arranged on the plate face, and there is through hole at the strip hole two ends; The bracing frame female parts is bundled on the low-voltage coil, and bracing frame folding surface and supporting plate tighten together, and supporting plate is fastened on the pour mass bottom surface with the epoxy glass fabric board spacer.
When the coiling current mutual inductor coil, at first the bracing frame female parts is attached on the low-voltage coil external diameter and is one around tying up with low-voltage coil; Then with holes of supporting plate counterbore and bracing frame are tightened together with bolt, nut; When the assembling current transformer, suitably cushioning square epoxy glass fabric board spacer under the through hole of supporting plate strip hole two ends is adjusted supporting plate and instrument transformer pour mass basal spacing, and promptly having guaranteed has enough insulating spaces between low-voltage coil and the high-tension coil.
The current transformer low-voltage coil location structure that the utility model provides makes coil stationary firm, and is easy to assembly, and the production efficiency height is simple in structure, constant product quality.
Description of drawings
Fig. 1 is the assembling schematic diagram of an embodiment of the utility model current transformer low-voltage coil location structure;
Fig. 2 is the structural representation of bracing frame embodiment illustrated in fig. 1;
Fig. 3 is the structural representation of supporting plate embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, low-voltage coil 2, high-tension coil 3, bracing frame 4, nut 5, supporting plate 6, bolt 7, epoxy glass fabric board spacer
As shown in the figure, bracing frame 3 is n shape structures of an inner concavity, and each inwardly is bent into 90 degree end portion, and through hole is arranged on the folding surface; Supporting plate 5 is rectangular slabs, and two rectangular through holes of counterbore shape are arranged on the plate face, and there is through hole at the strip hole two ends.Bracing frame 3 female parts are bundled on the low-voltage coil 1, and bracing frame 3 folding surfaces and supporting plate 5 are tightened together by bolt 6 and nut 4, and supporting plate 5 is fastened on the pour mass bottom surface with epoxy glass fabric board spacer 7.
When the coiling current mutual inductor coil, at first bracing frame 3 female parts are attached on low-voltage coil 1 external diameter and are one around tying up with low-voltage coil 1; Then 3 with holes of supporting plate 5 counterbores and bracing frames are tightened together with bolt 6 and nut 4; When the assembling current transformer, suitably cushioning square epoxy glass fabric board spacer 7 under supporting plate 5 strip hole two ends through holes is adjusted supporting plate 5 and instrument transformer pour mass basal spacing, and promptly having guaranteed has enough insulating spaces between low-voltage coil 1 and the high-tension coil 2.
