Description
Technical field
The utility model relates to a kind of voltage transformer, particularly relate to a kind of for exchanging 50Hz, in the following outdoor circuit of rated voltage 10kV and 10KV, a kind of voltage transformer that voltage supplied, electric energy measurement and protection are used.
Background technology
Outdoor voltage transformer is widely used in outdoor circuit, for voltage and electrolytic measurement and the circuit protection of circuit.The outdoor voltage transformer using at present, some insulation property are poor, and surface creepage distance is little, and security performance is poor.
Utility model content
The purpose of this utility model, is to provide a kind of outdoor composite insulation formula voltage transformer, improves surface creepage distance and insulation property, and safe and reliable to operation.
The technical scheme adopting is:
An outdoor composite insulation formula voltage transformer, comprises iron core, insulation shell, it is characterized in that:
Secondary coil winding, on secondary coil skeleton, and is sleeved on iron core; Primary winding winding, on primary winding skeleton, and is installed on secondary coil;
Iron core, secondary coil and primary winding are by poured with epoxy resin structure in aggregates, and epoxy resin poured body is insulation shell, is fixed with the silicone rubber insulation layer with full skirt on insulation shell outer wall; Insulation shell outer wall bottom is provided with secondary outlet box, has preventing fraudulent use of electricity guard shield and two secondary outgoing line holes on secondary outlet box; Two end lead-out wires of secondary coil are connected with the corresponding wiring terminal in secondary outlet box respectively; First of primary winding once goes between and is connected with the first connection inserting part, and second of primary winding once goes between and is connected with the second connection inserting part;
The upper surface of insulation shell is provided with the first insulation king-post and the second insulation king-post, and the first insulation king-post and the second insulation king-post and insulation shell are the overall structure by epoxy resin one-time cast-forming; The first connection inserting part and the second connection inserting part are encapsulated in respectively in the first insulation king-post and the second insulation king-post;
In the first insulation king-post and the second insulation king-post, be built-in with respectively the first fuse and the second fuse, the lower end of the first fuse is connected with the first connection inserting part, the upper end of the first fuse is connected with the first binding post, the lower end of the second fuse is connected with the second connection inserting part, and the upper end of the second fuse is connected with the second binding post.
On insulation shell lower surface, be fixed with two mounting seat.
Advantage of the present utility model:
The high-quality cold-reduced silicon sheet that adopts unshakable in one's determination of the present utility model, forms through the annealing of reeling, and iron loss is little, magnetic is close low, and product data are good, stable performance.Unshakable in one's determination with poured with epoxy resin, form together with winding and secondary winding, and be furnished with built-in replaceable formula fuse, need not install in addition, saved the various running costs of client; High-low pressure terminal of the present utility model is connected firmly, and secondary outgoing line is divided into two different directions, to facilitate outlet, and has anti-stealing electricity function.The utility model has adopted silicon rubber insulation, waterproof, antiultraviolet, anti-resin season cracking, and it is clear to identify.Type is umbrella skirt construction in addition, has improved surface creepage distance, and silicon rubber insulation intensity is stable and reliable for performance.Can be widely used in any environment, be desirable renewal product.
