The smelting bin comprises an epoxy resin shell, and a smelting bin front current-conducting piece, a smelting bin back current-conducting body and a melting bin grounding piece which are integrated with the epoxy resin shell through pressure injection, a smelting bin grounding end inserting piece, an insulating box inserting piece, a lead-out bushing sensor, a smelting bin bushing current-conducting rod and a smelting bin front shielding piece, wherein a smelting bin body shielding piece is arranged inside the epoxy resin shell; an included angle smaller than 90 degrees is formed between the epoxy resin shell and the smelting bin front current-conducting piece and between the epoxy resin shell and the smelting bin bushing current-conducting rod respectively; a smelting bin grounding end shielding piece is connected with the smelting bin grounding end inserting piece. The smelting bin body shielding piece is annular and is arranged in a two-section manner, in which one section is arranged on the side of the smelting bin front current-conducting piece and the other section is arranged on the side of the smelting bin back current-conducting body. The smelting bin can solve the problems caused by integral design of the smelting bin and an isolating switch or a load switch that the product processing difficulty is great, the production cost is high, the smelting bin is inconvenient to operate and high in partial discharge numerical value during operation and maintenance, and the service life of the product is influenced.
Description
Technical field
The present invention 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 present 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 present ring main unit is used, substantially adopt the shielding technology of pressure equalization in the molten storehouse that the fuse mid portion is corresponding, and its partial discharge numerical quantity is higher.Particularly after molten storehouse outer wall adopted the semiconductor material spraying, its partial discharge problem was 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 invention is to provide a kind of molten storehouse, it is large that it can solve the product difficulty of processing that brings 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 used in the present invention 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, be provided with molten warehouse shielding part in described epoxy resin housing; Have one 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 less than the angle of 90 °; 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 that has is in the present invention:
1, the design of with switch, separating is adopted in this molten storehouse, and the product installation, maintenance is convenient.
2, the form that is designed to tilt due to molten storehouse, 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, less than 1pc, has improved the useful life of product.
