Description
Technical field
The present invention relates to technical field of middle/high-voltage electrical appliance manufacture, 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 that urban network restructuring and user's controller switching equipment control, 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 that ring main unit runs.
Fuse in current solid insulation ring main unit melt storehouse mainly with isolating switch or on-load switch integrated design, the Product processing difficulty of such integrated design is larger; 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 ring main unit volume large, and production cost is high, is not easy to the operation of staff when operation maintenance; The molten storehouse of current ring main unit, the molten storehouse corresponding at fuse mid portion does not adopt shielding technology of pressure equalization substantially, and its partial discharge numerical quantity is higher.Particularly after molten storehouse outer wall adopts semiconductor material spraying, its partial discharge problem is especially outstanding, and numerical value is mostly at more than 5pc after tested, has a strong impact on the useful life of product.
Summary of the invention
The object of this invention is to provide a kind of molten storehouse, it is large that it can solve the Product processing difficulty 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 staff during operation maintenance are higher, affect the problem in the useful life of product.
In order to solve the problem, the technical solution used in the present invention is: this molten storehouse, comprise epoxy resin housing, electric conductor, molten storehouse earthing member behind electric-conductor before storehouse, molten storehouse is melted, molten storehouse earth terminal inserts, insulated case inserts with described epoxy resin housing pressure injection all-in-one-piece, 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; An angle being less than 90 ° is had 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; 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 of layouts, one section of side at electric-conductor before described molten storehouse, one section of side at electric conductor behind described molten storehouse.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention:
1, this molten storehouse adopts the design of separating with switch, and product installation, maintenance is convenient.
2, because molten storehouse is designed to the form of inclination, so the volume of ring main unit reduces, production cost reduces.
3, add shielding part (being all installed with meter) in this molten storehouse, solve the problem that product partial discharge value is high, the partial discharge value in this molten storehouse is less than 1pc, improves the useful life of product.
Accompanying drawing explanation
Fig. 1 is the structural representation in molten storehouse.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Molten storehouse shown in Fig. 1, before molten storehouse, electric-conductor 1 pressure injection is in epoxy resin housing 2, for being connected with isolating switch or on-load switch.Molten warehouse shielding part 3 is divided into two sections, one section of side at electric-conductor 1 before molten storehouse, and one section, in the side of electric conductor 4 behind molten storehouse, surrounds the conducting position at fusion tube two ends respectively; Behind molten storehouse, electric conductor 4 is communicated with molten storehouse sleeve pipe contact rod 9 and is communicated with external equipment; Make molten storehouse ground connection and be connected with electric conductor 4 behind molten storehouse with bolt when molten storehouse earthing member 5 is for overhauling; Molten storehouse earth terminal inserts 6 for retainer ring epoxy resins housing 2, and is connected to form electric conductor by bolt and molten storehouse earth terminal shielding part 12; Insulated case inserts 7 is for fixing molten Cang Gai; Whether outlet casing tube transducer 8 has electricity for detecting electric conductor in molten storehouse; Soket head cap screw 10 is for electric-conductor 4 and molten storehouse sleeve pipe contact rod 9 behind fixing molten storehouse; Before molten storehouse, shielding part 11 is for improving the Electric Field Distribution before fusion tube and molten storehouse between electric-conductor 1, reduces partial discharge value; Molten storehouse earth terminal shielding part 12, for improving the Electric Field Distribution of earth terminal, reduces earth terminal partial discharge value; Crosshead groove pan head screw 13 is for fixing molten storehouse earth terminal inserts 6 and molten storehouse earth terminal shielding part 12.An angle being less than 90 ° is had between the axis of electric-conductor 1 and the axis of epoxy resin housing 2 before molten storehouse; An angle being less than 90 ° is had between the axis of molten storehouse sleeve pipe contact rod 9 and the axis of epoxy resin housing 2.
