Abstract
The utility model discloses a cable used in a transformer lifting seat. The cable comprises a cable core which is externally provided with a cladding layer. The cladding layer is externally cladded with a corrugated paper board insulating layer. The corrugated paper board insulating layer is cladded on the outer side of the cable used in the transformer lifting seat to replace an insulating sleeve pipe in the prior art; and the corrugated paper board insulating layer not only is simple in structure, convenient in processing, relatively low in manufacture cost, and convenient in installation, but also is small in magnitude of partial discharge and good in insulating effect, and is safe and reliable.
Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of for the cable in power transformer enclosure.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.
Generally all be provided with current transformer in the rising seat of existing high-tension transformer; be used for measuring the electric current of cable; and play the effect of protection; because the voltage of cable is higher; general is all to establish sleeve pipe playing the effect of insulation at cable jacket, yet because the insulating requirements to sleeve pipe is high, so the sleeve pipe cost of manufacture is higher; and sleeve pipe is installed inconvenient, still has the large problem of partial discharge quantity.
The utility model content
The technical problem that the utility model mainly solves is to provide that a kind of simple in structure, weight is light, cost of manufacture is low, insulation effect is good is used for cable in power transformer enclosure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of for the cable in power transformer enclosure, comprise cable conductor, described cable conductor is provided with coating layer outward, described coating layer is surrounded by the corrugated board insulating barrier outward, described corrugated board insulating barrier is double wall corrugated board, passes through the adhesive adhesion between described double wall corrugated board.
In preferred embodiment of the utility model, described corrugated board thickness of insulating layer is 5-10mm.
In preferred embodiment of the utility model, described Double layer corrugated paper plate thickness is identical.
The beneficial effects of the utility model are: the utility model is used for the interior cable of power transformer enclosure owing to being surrounded by the corrugated board insulating barrier outside cable, substituted insulating sleeve of the prior art, corrugated board structure is simple, easy to process, cost of manufacture is lower, be convenient to install, and partial discharge quantity is few, insulation effect is good, and is safe and reliable.
Description of drawings
Fig. 1 is the perspective view that the utility model is used for cable one preferred embodiment in power transformer enclosure;
In accompanying drawing, the mark of each parts is as follows: 1, cable conductor, 2, coating layer, 3, the corrugated board insulating barrier.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
A kind of for the cable in power transformer enclosure, comprise cable conductor 1, the outer coating layer 2 that is provided with of described cable conductor 1, the outer corrugated board insulating barrier 3 that is surrounded by of described coating layer 2.
In the utility model, corrugated board insulating barrier 3 is preferably and is double wall corrugated board, and between double wall corrugated board, by the adhesive adhesion, sound construction is reliable, long service life.
Described corrugated board insulating barrier 3 thickness are 5-10mm, and two-layer corrugated board thickness is identical.
When this cable was arranged in power transformer enclosure, the cable jacket of end had current sensor, separated by double wall corrugated board between current sensor and cable, and partial discharge quantity is few, and insulation effect is good.
Compared with prior art, the utility model is used for the interior cable of power transformer enclosure owing to being surrounded by corrugated board insulating barrier 3 outside cable, substituted insulating sleeve of the prior art, corrugated board structure is simple, and is easy to process, and cost of manufacture is lower, be convenient to install, and partial discharge quantity is few, and insulation effect is good, and is safe and reliable.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
