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 is and in particular to a kind of fuse insulating cylinder.
Background technology
With scientific and technical continuous progress, the requirement more and more higher to distribution products for the mankind, environmental protection, energy-conservation, intelligence, exempt from
Safeguard, the developing direction becoming ring main unit such as highly reliable and inexpensive, under this background, solid insulation ring main unit meet the tendency and
Raw, solid insulation ring main unit has fully phased out sf6 gas and corresponding gas tank part on structural principle, using insulating sleeve solidification
Switch block, connects each loop by enclosed busbar, integrally realizes totally-enclosed all insulation.For from manufacturing, phase and phase is point
Every；For electric learning, alternate will not short circuit.It does not have the parts such as pressure gas tank, relief valve, is truly realized non-maintaining.
For solid isolated vacuum ring main unit, standard require " switch-fuse combination, after on-load switch separating brake, current limliting
Reliable ground is answered at fuse two ends ".Existing combined electrical apparatus scheme, after vacuum load switch separating brake, is passed through before limiting fuse
Three-station ground connection and on-load switch close a floodgate and to be grounded, and rear end suspends or by an independent ground switch earthing,
Its complex structure, high cost, and do not possess ground connection close energy.
Content of the invention
The present invention is directed to problems of the prior art, provides a kind of fuse insulating cylinder.
The fuse insulating cylinder of the present invention, including insulating part body and cableport thereon and load ports, described exhausted
Edge part body includes placing the cavity of fuse and its shorting switch cavity of upper end；One end of cavity is provided with front socket, another
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, the other end and first
Conductor connects；Load ports are located at the upper end of cavity, and its second conductor is connected with rear socket；It is provided with described shorting switch cavity
Second static contact fixing with the second conductor and be fixed on the first static contact on insulating part body, moving contact is slidably arranged in the
Between the fingertip of one static contact and the second static contact；First static contact is connected with front socket by the second wire.
In order to realize the machine driving of moving contact, and ensure moving contact and extraneous insulating requirements, described moving contact is remote
One end from the second static contact is provided with insulated tension pole.
For effective insulation of shorting switch cavity electrical body, described shorting switch cavity is provided with closure.
Installation in order to realize fuse insulating cylinder is fixed, and described insulating part body is provided with flange.
The fuse insulating cylinder of the present invention, it is designed with the shorting switch of leading-out terminal before and after fuse, can pass through three stations
Switch ground connection, linkage shorting switch closes a floodgate, then it is molten to combine the current limliting realizing having making capability to carry out on-load switch combined floodgate
Reliable ground is answered at disconnected device two ends.
Hinge structure of the present invention has the advantage that
1st, the fuse insulating barrel structure of the present invention, it is designed with the shorting switch of leading-out terminal before and after fuse, can pass through
Three-station be grounded, linkage shorting switch close a floodgate, then carry out on-load switch close a floodgate to combine realize there is making capability
Reliable ground is answered at limiting fuse two ends.
2nd, present configuration is simple, function is complete, small volume, and reliability is high, low cost.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the side view of Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing, the fuse insulating cylinder of the present invention is described in further detail.
Fuse insulating cylinder as shown in Figure 1 and Figure 2, including insulating part body 19 and cableport thereon 1 and load side
Mouth 10, described insulating part body 19 includes placing the cavity 14 of fuse and its shorting switch cavity 5 of upper end；The one of cavity 14
End 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 the one of its first wire 17
End is connected with front socket 16, and the other end is connected with the first conductor 18；Load ports 10 are located at the upper end of cavity 14, its second conductor
11 are connected with rear socket 12；It is provided with second static contact 9 fixing with the second conductor 11 in described shorting switch cavity 5 and be fixed on
The first static contact 6 on insulating part body 19, moving contact 8 is slidably arranged in the first static contact 6 and the fingertip 7 of the second static contact 9
Between；First static contact 6 is connected with front socket 16 by the second wire 15；Moving contact 8 is provided with away from one end of the second static contact 9
Insulated tension pole 4；Shorting switch cavity 5 is provided with closure 2；Insulating part body 19 is provided with flange 13.
The front socket 16 of its interior forward end of insulating part body 19 cast conductor fuse, the first wire 17, the second wire 15,
Three is sequentially connected；Rear end cast conductor fuse rear socket 12 is connected with the second conductor 11；Fuse insulating barrel structure passes through
Flange 13 on insulating part body 19 is fixed and is installed on cabinet body frame, and major loop is fixed on by load ports 10 in rear end
It is ensured that installing stable on insulating part.
Fuse insulating cylinder is formed combined electrical apparatus together with tri-station isolating switch, vacuum load switch and uses, when normal
During use, shorting switch be gate-dividing state, that is, insulated tension pole 4 drive moving contact 8 be moved to the left, moving contact 8 only with the first stationary contact
6 are electrically coupled by fingertip 7, and at this moment moving contact 8 and the second static contact 9 are completely separable and form air fracture, and electric current warp
Fuse reaches major loop.After fuse blows, when needing to change fuse, operation tri-station isolating switch is to ground connection position
Put, now linkage shorting switch insulated tension pole 4 moves right, it drives moving contact 8 to reach closing position, now fuse
Two ends are linked together by shorting switch, at this moment combined floodgate on-load switch, are just smoothly grounded the two ends of fuse simultaneously, due to
Using vacuum load switch, therefore it closes ground connection and can easily realize making capability.
