Abstract
The utility model relates to the technical field of transformers, in particular to an electronic bushing current transformer assembled outside a high-voltage combined electric appliance, which is suitable for current measurement, monitoring and relay protection of AC power systems below 1000KV. The bushing current transformer comprises a baseplate and a casing, wherein Rogowski coils and low-power-consumption coils are mounted in the casing through resin casting; and the baseplate is directly assembled at the grounding terminal of a high-voltage bushing of the combined electric appliance or on the outer side of a bus tube. The bushing current transformer provided by the utility model overcomes the shortcomings of a traditional electromagnetic transformer, such as large size, heavy weight, high probability of saturation and poor linearity degree, has simple structure and small size, and is an updated product for the traditional electromagnetic current transformer.
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 pressure combined electrical apparatus outside can be applied in three-phase or the single-phase high voltage combined electrical apparatus.
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 the transformer outside.
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 pressure combined electrical apparatus outside 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 pressure combined electrical apparatus outside, comprise base plate and shell, described housings is equipped with Luo-coil and low-power consumption coil, and described Luo-coil and low-power consumption coil are with resin-cast in the enclosure.
Described base plate directly is assemblied in the combined electrical apparatus bushing earth terminal or the bus bar canister outside.
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.
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 base plate 4 and shell 5, and described shell 5 the insides are equipped with Luo-coil 1 and low-power consumption coil 2, and described Luo-coil 1 and low-power consumption coil 2 usefulness resins 3 are cast in the shell 5; Described base plate 4 directly is assemblied in the combined electrical apparatus bushing earth terminal or the bus bar canister outside.
Luo-coil 1 and low-power consumption coil 2 in shell 5, lay on request and lead-out wire after, resin 3 is poured onto reaches in the shell 5 when burying Luo-coil 1 and low-power consumption coil 2, wait for that resin 3 solidifies, then base plate 4 is installed on the shell 5, can be installed to relevant position, high pressure combined electrical apparatus bus bar canister outside by base plate 4 then.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, 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 that above embodiment did according to technical spirit of the present utility model.
Claims (2)
1. electronic type casing current transformer that is assemblied in high pressure combined electrical apparatus outside, it is characterized in that: comprise base plate and shell, described housings is equipped with Luo-coil and low-power consumption coil, and described Luo-coil and low-power consumption coil are with resin-cast in the enclosure.
2. a kind of electronic type casing current transformer that is assemblied in high pressure combined electrical apparatus outside according to claim 1 is characterized in that: described base plate directly is assemblied in the combined electrical apparatus bushing earth terminal or the bus bar canister outside.
