Abstract
The utility model relates to the high-voltage GIS appliance manufacture field, in particular to an integral-pouring type high-voltage GIS current transformer, comprising a shield barrel and a plurality of coils sheathed on the outer wall of the shield barrel in an overlapped manner. The GIS current transformer is characterized in that a barrel-shaped glass silk grid is arranged on the position close to the outer ring of the coil, and the glass silk grid, the coils and the outer wall of the shield barrel are poured into a whole via epoxy resin.
Description
Technical field
The utility model relates to high pressure GIS electrical equipment and makes field, particularly a kind of integrated casting type high pressure GIS current transformer.
Background technology
High pressure GIS current transformer is as one of vitals of GIS electrical equipment, and technology is the single employing poured with epoxy resin of coil of current transformer usually, and then luggage is joined.The workload of poured with epoxy resin operation is very big, simultaneously in order to prevent coil play in transit, carrying out crimping with semi-ring when coil assembles fixes, the stationary half of need on the shielding cylinder that is positioned at the coil inner ring, slotting, the slotting position of shielding cylinder changes with the variation of coil height, causes the versatility of shielding cylinder very poor.
Summary of the invention
The object of the present invention is to provide a kind of integrated casting type high pressure GIS current transformer, it is integrated poured that coil is assembled laggard row, can reduce the workload of poured with epoxy resin operation, need not process shielding cylinder and just can prevent coil play in transit.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of integrated casting type high pressure GIS current transformer, comprise shielding cylinder, be sleeved on many stacked coils of shielding cylinder outer wall, it is characterized in that, be provided with the glass fiber grid of tubular near the coil outer ring, glass fiber grid, coil, shielding cylinder outer wall are as a whole by poured with epoxy resin.
Further improvement of the utility model and characteristics are:
(1) close coil inner ring also is provided with the glass fiber grid that passes through poured with epoxy resin of tubular.
(2) mesh of described glass fiber grid is a square, and its length of side is 10～15mm.
In the utility model, be respectively arranged with the glass fiber grid of tubular near coil outer ring and inner ring, glass fiber grid, coil, shielding cylinder outer wall are as a whole by poured with epoxy resin; Simplified the pouring technology of coil, saved all parts (semi-ring and crimping screw rod etc.) of fixed coil, need on shielding cylinder, not slot, increased the versatility of shielding, the coil assembling has been oversimplified, and solved the coil problem of play in transit.
Description of drawings
Knot description of drawings and embodiment are described in further details the present invention below.
Fig. 1 is the integrated casting type high pressure GIS current transformer structural representation of a kind of 800kV;
Among the figure: 1 is shielding cylinder; 2 is coil; 3 is epoxy resin; 4 is backing plate; 5 is the glass fiber grid.
Embodiment
With reference to Fig. 1, integrated casting type high pressure GIS current transformer for a kind of 800kV, mainly comprise: shielding cylinder 1, be sleeved on 5 stacked coils 2 of shielding cylinder 1 outer wall, be provided with backing plate 4 between every coil 2, close coil 2 outer rings and inner ring are respectively arranged with the glass fiber grid 5 of tubular, glass fiber grid 5, coil 2, shielding cylinder 1 outer wall are poured into a mould as a whole by epoxy resin 3. in the present embodiment, the mesh of glass fiber grid 5 is a square, its best length of side is 15mm, also can be between 10～15mm.
During cast, earlier integrated poured mould is assemblied on the shielding cylinder 1, again coil 2 is packed in the casting mold according to putting in order of customer requirements, backing plate 4 is set between the coil 2, then on the inwall of the outer wall of shielding cylinder 1 and casting mold, with adhesive tape glass fiber grid 5 is fixed, carry out integrated poured with the poured with epoxy resin material at last.In casting process, slow down the speed of batch turning, in batch turning, epoxy resin is fully stirred, gas is thoroughly discharged, can increase the intensity and the toughness of product like this, solve coil cracking problem.
Claims (3)
1. integrated casting type high pressure GIS current transformer, comprise shielding cylinder, be sleeved on many stacked coils of shielding cylinder outer wall, it is characterized in that, be provided with the glass fiber grid of tubular near the coil outer ring, glass fiber grid, coil, shielding cylinder outer wall are as a whole by poured with epoxy resin.
2. a kind of integrated casting type high pressure GIS current transformer according to claim 1 is characterized in that, also is provided with the glass fiber grid that passes through poured with epoxy resin of tubular near the coil inner ring.
