Abstract
The invention provides a fuse insulating cylinder of a novel composite electrical appliance scheme so as to solve the problems that an existing composite electrical appliance scheme is complex in structure and high in cost. According to the structure of the fuse insulating cylinder, a short circuit switch for the front wire outlet end and the rear wire outlet end of a fuse is arranged according to the design, the fuse insulating cylinder can be grounded through a three-position switch and be switched on in linkage with the short circuit switch, and then the two ends of the current-limiting fuse with the closing capability are reliably grounded by means of switching on a load switch in a combined mode. The fuse insulating cylinder has the advantages of being simple in structure, small in size, high in reliability, low in cost and the like; besides, the fuse insulating cylinder has complete functions.
Description
Technical field
The present invention relates to distribution technique field, be specifically related to a kind of fuse insulating cylinder.
Background technology
Continuous progress along with science and technology, the mankind are more and more higher to the requirement of distribution product, environmental protection, energy-conservation, intelligent, non-maintaining, highly reliable and low-cost etc. becomes the developing direction of ring main unit, under this background, solid insulation ring main unit arises at the historic moment, and solid insulation ring main unit has fully phased out SF6 gas and corresponding gas tank parts on structural principle, adopts insulating sleeve to solidify switch block, by enclosed busbar, connect each loop, integral body realizes totally-enclosed all insulation.From manufacturing, phase and phase is separated; From electric, alternate can short circuit.It does not have the parts such as pressure gas tank, relief valve, has really realized non-maintaining.For solid isolated vacuum ring main unit, standard-required " switch-fuse combination, after on-load switch separating brake, reliable ground is answered at current limiting fuse two ends ".Existing combined electrical apparatus scheme is after vacuum load switch separating brake, before current limiting fuse, by three-station ground connection and on-load switch, close a floodgate to be grounded, rear end suspends or passes through an independently ground switch earthing, its complex structure, cost is high, and does not possess the energy that closes of ground connection.
Summary of the invention
The present invention is directed to problems of the prior art, a kind of fuse insulating cylinder is provided.
Fuse insulating cylinder of the present invention, comprise insulating part body and on cableport and load ports, described insulating part body comprises places the cavity of fuse and the shorting switch cavity of upper end thereof; One end of cavity is provided with front socket, and the other end is provided with rear socket; Cableport is located at the lower end of cavity, and one end of its first wire is connected with front socket, and the other end is connected with the first conductor; Load ports is located at the upper end of cavity, and its second conductor is connected with rear socket; In described shorting switch cavity, be provided with second fixed contact fixing with the second conductor and be fixed on the first fixed contact on insulating part body, moving contact is slidably arranged between the first fixed contact and the fingertip of the second fixed contact; The first fixed contact is connected with front socket by the second wire.
In order to realize the machine driving of moving contact, and guarantee moving contact and extraneous insulating requirements, described moving contact is provided with insulated tension pole away from one end of the second fixed contact.
For effective insulation of shorting switch cavity electrified body, described shorting switch cavity is provided with seal cover.
In order to realize the installation of fuse insulating cylinder, fix, described insulating part body is provided with flange.
Fuse insulating cylinder of the present invention, it is designed with the shorting switch of fuse front and back leading-out terminal, can pass through three-station ground connection, linkage shorting switch closes a floodgate, then carries out on-load switch and close a floodgate to combine and realize the current limiting fuse two ends with making capability and answer reliable ground.
The present invention is relative, and prior art has the following advantages:
1, fuse insulating barrel structure of the present invention, it is designed with the shorting switch of fuse front and back leading-out terminal, can pass through three-station ground connection, linkage shorting switch closes a floodgate, then carries out on-load switch and close a floodgate to combine and realize the current limiting fuse two ends with making capability and answer reliable ground.
2, the present invention is simple in structure, function is complete, volume is little, and reliability is high, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the end view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, fuse insulating cylinder of the present invention is described in further detail.
Fuse insulating cylinder as shown in Figure 1 and Figure 2, comprise insulating part body 19 and on cableport 1 and load ports 10, described insulating part body 19 comprises places the cavity 14 of fuse and the shorting switch cavity 5 of upper end thereof; One end of cavity 14 is provided with front socket 16, and the other end is provided with rear socket 12; Cableport 1 is located at the lower end of cavity 14, and one end of its first wire 17 is connected with front socket 16, and the other end is connected with the first conductor 18; Load ports 10 is located at the upper end of cavity 14, and its second conductor 11 is connected with rear socket 12; In described shorting switch cavity 5, be provided with second fixed contact 9 fixing with the second conductor 11 and be fixed on the first fixed contact 6 on insulating part body 19, moving contact 8 is slidably arranged between the first fixed contact 6 and the fingertip 7 of the second fixed contact 9; The first fixed contact 6 is connected with front socket 16 by the second wire 15; Moving contact 8 is provided with insulated tension pole 4 away from one end of the second fixed contact 9; Shorting switch cavity 5 is provided with seal cover 2; Insulating part body 19 is provided with flange 13.
Fuse insulating cylinder forms combined electrical apparatus together with tri-station isolating switch, vacuum load switch to be used, when normal use, shorting switch is gate-dividing state, be that insulated tension pole 4 drives moving contact 8 to be moved to the left, 8 of moving contacts connect by fingertip 7 is electric with the first fixed contact 6, at this moment moving contact 8 separates completely and forms air fracture with the second fixed contact 9, and electric current arrives major loop through fuse.After fuse blows, in the time of need to changing fuse, operation tri-station isolating switch is to earthing position, now linkage shorting switch insulated tension pole 4 moves right, and it drives moving contact 8 to arrive closing position, and now the two ends of fuse link together by shorting switch, at this moment on-load switch closes a floodgate, just, smoothly by the two ends while ground connection of fuse, owing to adopting vacuum load switch, therefore closing ground connection, it can easily realize making capability.
