Description
Technical field
The utility model relates to mesohigh electrical equipment manufacturing technology field, especially a kind of molten storehouse of mesohigh fuse.
Background technology
Solid insulation ring main unit is current ring main unit Hot spots for development, and as the key equipment of urban network restructuring and the control of user's controller switching equipment, the quality of ring main unit quality is directly connected to the safety and reliability of transmission system.Fuse is as one of ring main unit important components and parts, and the quality of its quality is directly connected to the safety and reliability of ring main unit operation.
The molten storehouse of fuse in solid insulation ring main unit is mainly and isolating switch or on-load switch integrated design that the product difficulty of processing of integrated design is larger so at present; The molten storehouse of integrated design adopts vertical 1 font or horizontal in-line to be connected with isolating switch or on-load switch mostly, and such connected mode can cause the ring main unit volume large, and production cost is high, is not easy to staff's operation when operation maintenance; The molten storehouse that ring main unit is used at present, the molten storehouse corresponding at the fuse mid portion do not adopt the shielding technology of pressure equalization substantially, and its partial discharge numerical quantity is higher.Particularly, after molten storehouse outer wall adopts the semiconductor material spraying, its partial discharge problem is especially outstanding, and numerical value mostly, more than 5pc, has a strong impact on the useful life of product after tested.
Summary of the invention
The purpose of this utility model is to provide a kind of molten storehouse, it is large that it can solve the product difficulty of processing brought in molten storehouse and isolating switch or on-load switch integrated design, production cost is high, the operation and the partial discharge numerical value that are not easy to the staff during operation maintenance are higher, affect the problem in the useful life of product.
In order to address the above problem, the technical solution adopted in the utility model is: this molten storehouse, comprise the epoxy resin housing, with electric conductor, molten storehouse earthing member behind electric-conductor, molten storehouse before the molten storehouse of described epoxy resin housing pressure injection all-in-one-piece, molten storehouse earth terminal inserts, insulated case inserts, the outlet casing tube transducer, molten storehouse sleeve pipe contact rod, shielding part before molten storehouse is provided with molten warehouse shielding part in described epoxy resin housing; Between the axis of the axis of this epoxy resin housing electric-conductor respectively and before described molten storehouse and the axis of described molten storehouse sleeve pipe contact rod, an angle that is less than 90 ° is arranged; Molten storehouse earth terminal shielding part is connected with described molten storehouse earth terminal inserts.
In technique scheme, more specifically scheme can also be: described molten warehouse shielding part is ring-type and is divided into two sections layouts, a side of one section electric-conductor before close described molten storehouse, and one section in the side near electric conductor behind described molten storehouse.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect had is the utility model:
1, this molten storehouse adopts the design of separating with switch, and the product installation, maintenance is convenient.
2, because molten storehouse is designed to the form tilted, so the volume of ring main unit has reduced, production cost has reduced.
3, increased shielding part (all being installed with meter) in this molten storehouse, solved the high problem of product partial discharge value, the partial discharge value in this molten storehouse is less than 1pc, has improved the useful life of product.
The accompanying drawing explanation
Fig. 1 is the structural representation in molten storehouse.
Embodiment
