Abstract
The utility model relates to the technical field of mutual inductors, in particular to an electronic sleeve current mutual inductor assembled in a high-voltage transformer, which is applicable to realizing current measurement, monitoring and relay protection for an alternating-current electrical power system with maximum voltage of 1000KV. The electronic sleeve current mutual inductor comprises a rising seat shell, a rising seat upper cover plate, an electronic sleeve current mutual inductor body, a press plate and a fixing screw stem, the electronic sleeve current mutual inductor body is mounted on the rising seat upper cover plate in a pressed manner via the press plate and the fixing screw stem, a secondary lead is led out via a secondary wiring box, and the electronic sleeve current mutual inductor body is hoisted in a rising seat. The electronic sleeve current mutual inductor assembled in the high-voltage transformer overcomes shortages that a traditional electromagnetic mutual inductor is large in volume, heavy in weight, easy to be saturated and poor in linearity, is simple in structure and small in volume, and is a product for replacing the traditional electromagnetic current mutual inductor.
Description
Technical field
The utility model relates to the instrument transformer technical field, and especially a kind of electronic type casing current transformer that is assemblied in high-tension transformer inside can be applied in three-phase or single-phase high voltage transformer, the special transformer.
Background technology
The tradition electromagnetic transformer has that volume is big, weight big and shortcoming easily saturated, poor linearity.Country " 12. five " want the all-round construction intelligent grid in the phase, and electronic current mutual inductor is as the visual plant of measurement circuitry and device current signal, must have very big demand, so we have designed the electronic type casing current transformer that is assemblied in transformer inside.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned technical disadvantages, a kind of electronic type casing current transformer that is assemblied in high-tension transformer inside to be provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of electronic type casing current transformer that is assemblied in high-tension transformer inside, comprise the seat shell that raises, a rising seat upper cover plate, electronic type casing current transformer, pressing plate and standing screw, described electronic type casing current transformer is fitted in the seat upper cover plate that raises by pressing plate and standing screw, and secondary lead wires is drawn by the secondary connection box.
Described electronic type casing current transformer is lifted in the seat that raises.
Described rising seat shell is made by aluminium, aluminium enclosure spraying one deck epoxy primer.
The beneficial effect that the utility model had is:
1, the utility model structural design is simple, and volume is little, and is in light weight.
2, the signal linearity is good, and measuring range is wide, and transient performance is superior, stable output signal, and antijamming capability is strong, and reliable with the screw rod fixation.
Description of drawings
Accompanying drawing is a front view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done following detailed description.
As shown in the figure, the utility model comprises the seat shell 6 that raises, seat upper cover plate 1, electronic type casing current transformer 2, pressing plate 3 and standing screw 4 raise, described electronic type casing current transformer 2 is fitted in the seat upper cover plate 1 that raises by pressing plate 3 and standing screw 4, and secondary lead wires is drawn by secondary connection box 5; Described electronic type casing current transformer 2 is lifted in the seat that raises; Described rising seat shell 6 is made aluminium enclosure spraying one deck epoxy primer by aluminium.The utility model is mainly used in current measurement, monitoring and relaying protection, and the purpose of the utility model product provides a kind of new-style electronic casing current transformer, electromagnetic current transducer before replacing, and dwindled overall dimension greatly.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
