Abstract
The utility model relates to the technology field of transformers, and particularly relates to a bushing type current transformer used for a high voltage transformer and a high voltage combined electric appliance, the bushing type current transformer is suitable for current measurement and protection for an oil-immersed transformer and a high voltage combined electric appliance of a lower-than-1000 KV alternating current system, the bushing type current transformer comprises a current transformer, epoxy resin, a resin housing, and a resin cover plate, the transformer is fixed in the resin housing; transformer original lead wires are directly used for secondary lead wires, and casting of binding posts on the resin housing is not needed; the bushing type current transformer in the utility model is advantaged by simple structure and stable performance, and is provided with current measurement and protection functions for a lower-than-1000 KV alternating current system.
Description
Technical field
The utility model relates to the instrument transformer technical field, especially relates to a kind of bushing current transformer that is used for high-tension transformer and high pressure combined electrical apparatus, is applicable to that the following AC electric power systems of 1000KV makes current measurement, monitoring and used for relay protection.
Background technology
High-tension transformer and high pressure combined electrical apparatus are prone to cause instrument transformer to squeeze quality problems such as bad lead with the not science fit that the bushing current transformer fit on exists plug to adorn, and exist in the transportation in addition to be prone to cause product to break problem, are not easy to transport for long-distance.The utility model technology has solved this two big technical barrier.
The utility model content
The purpose of the utility model is in order to overcome above-mentioned technical disadvantages, a kind of bushing current transformer that is used for high-tension transformer and high pressure combined electrical apparatus to be provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of bushing current transformer that is used for high-tension transformer and high pressure combined electrical apparatus; It is characterized in that: comprise current transformer, epoxy resin, resin enclosure, resin cover plate, instrument transformer is fixed in the resin enclosure.
Secondary lead wires is directly used the former lead-in wire of instrument transformer, pours into a mould binding post on the resin enclosure and not be used in.
The beneficial effect that the utility model had is:
The utility model is simple in structure, the product good insulation preformance, is prone to assembling, transportation safety, cost of transportation is reduced.
Description of drawings
Accompanying drawing is the cutaway view of the 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 current transformer 1, epoxy resin 2, resin enclosure 4, resin cover plate 3, and instrument transformer 1 is fixed in the resin enclosure 4; Secondary lead wires is directly used the former lead-in wire of instrument transformer, pours into a mould binding post on the resin enclosure and not be used in.Instrument transformer 1 is positioned in the resin enclosure 4 on request, waters epoxy resin 2 then to be placed in the resin enclosure 4, gets on the 3 usefulness resin bondings of resin cover plate at last, and draws lead-in wire, can use after waiting resin solidification.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every the utility model technical scheme content that do not break away from, all still belongs in the scope of the utility model technical scheme any simple modification that above embodiment did according to the technical spirit of the utility model.
