Abstract
The utility model discloses a through-wall type high-voltage current transformer with a chain structure. The through-wall type high-voltage current transformer with the chain structure comprises a shell. An annular iron core is arranged in the shell. A primary coil is wound on the annular iron core. Secondary coils which are coupled with the primary coil and distributed in a spaced mode are arranged on the annular iron core. A wiring board electrically connected with the secondary coils is arranged on the outer wall of the shell. Secondary wiring terminals are arranged on the wiring board. The two ends of the shell are provided with primary wiring posts which extend out of the shell and are electrically connected with the primary coil. A plurality of conical columns evenly distributed are arranged on the inner wall of a cavity of the shell. The end of each conical column is provided with a steel wire braiding tube. An epoxy resin layer is poured in the shell at a time. The epoxy resin layer, the primary coil, the secondary coils, the annular iron core, the conical columns and the steel wire braiding tubes are combined into a whole. According to the through-wall type high-voltage current transformer, the structures such as the conical columns and the steel wire braiding tubes are arranged in the shell of the transformer, on one hand, the stability and the vacuum degree of the integral structure are improved after pouring is completed, on the other hand, the through-wall type high-voltage current transformer plays a role in shielding, and the interference of the outside on the through-wall type high-voltage current transformer is reduced.
Description
technical field:
The utility model relates to current transformer, relates in particular to a kind of chain structure wall-penetrating type high-tension current inductor.
background technology:
For the high-tension current inductor of chain structure, original casting is placed, can not guarantee that annular core, primary winding, secondary coil form a complete pour mass in instrument transformer housing, make in use to there will be partial discharge phenomenon, current transformer discharges for a long time can affect the correct judgement to the main insulation defect of instrument transformer own, brings larger hidden danger to the safe operation of system.
Therefore, need structure reasonable in design, guarantee the stability of current transformer internal structure, improve the vacuum degree after casting epoxy resin, the generation of stopping above-mentioned phenomenon.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of chain structure wall-penetrating type high-tension current inductor, and structural design novelty can effectively improve integrally-built stability after casting complete, gas clean-up, reduces the generation of partial discharge phenomenon.
The technical solution of the utility model is as follows:
Chain structure wall-penetrating type high-tension current inductor, comprise housing, in housing, be provided with annular core, on annular core, be wound with primary winding, annular core is provided with the spaced apart secondary coil intercoupling with primary winding, housing outer wall is provided with the terminal block being electrically connected with secondary coil, terminal block is provided with secondary wiring terminals, housing two ends are provided with stretches out outside housing, the primary connection bar being electrically connected with primary winding, it is characterized in that: the cavity inner wall of described housing is provided with many equally distributed tapered poles, tapered pole end is provided with braided steel wire cylinder, in housing, disposal pouring has epoxy resin layer, epoxy resin layer and primary winding, secondary coil, annular core, tapered pole, braided steel wire cylinder is integrally formed.
Described chain structure wall-penetrating type high-tension current inductor, is characterized in that: the count of described braided steel wire cylinder is not less than 85%.
The utility model has the advantages that:
The utility model structural design novelty, by be provided with the structure such as tapered pole, braided steel wire cylinder in instrument transformer housing, improve overall structure stability and the vacuum degree after casting complete on the one hand, also play on the other hand the effect of shielding, be subject to extraneous interference reduction, job stability improves.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1:
Chain structure wall-penetrating type high-tension current inductor, comprise housing 1, in housing 1, be provided with annular core 2, on annular core 2, be wound with primary winding 3, annular core 2 is provided with the spaced apart secondary coil 4 intercoupling with primary winding 3, housing 1 outer wall is provided with the terminal block 5 being electrically connected with secondary coil 4, terminal block 5 is provided with secondary wiring terminals 6, housing 1 two ends are provided with stretches out outside housing, the primary connection bar 7 being electrically connected with primary winding 3, the cavity inner wall of housing 1 is provided with many equally distributed tapered poles 8, tapered pole 8 ends are provided with braided steel wire cylinder 9, the interior disposal pouring of housing 1 has epoxy resin layer 10, epoxy resin layer 10 and primary winding 3, secondary coil 4, annular core 2, tapered pole 8, braided steel wire cylinder 9 is integrally formed.
The count of braided steel wire cylinder 9 is not less than 85%, and count is mainly to determine according to actual conditions, can after housing primary shielding, carry out secondary shield, reduces the impact that is subject to outer signals.
