Description
Technical field
The utility model relates to field of track traffic, in particular to a kind of high-voltage electricity PT fuse withdrawing device.
Background technique
Line of Nanjing Subway rail traffic mostly uses greatly the 35KV high-tension switch cabinet of Shenyang high pressure.In every set 35KV system mesohigh
Vacuum circuit breaker PT(hereinafter referred to as PT), it is that the control protection in voltage rating 35KV, 50HZ AC three-phase high voltage distribution network is set
It is standby.It is mainly used for breaking, closes load current, overload current and short circuit current in power circuit.Suitable for transformer substation system
Make protection and control is used, also can be used as the block switch of power grid, installs additional after controller, it can be achieved that distribution automation.
But equipment, through operation in a few years, PT is often easy to happen failure due to itself.However take out failure
PT fuse it is extremely difficult, be easy and the cavity in cabinet shell in moving process due to being enclosed with the PT fuse of rubber structure
Between form vacuum pressure, so it is bigger to want the difficulty of directly pulling out PT fuse outward.Maintenance personnel by PT fuse from
Frequent Fructus Forsythiae band pulls when taking out in cabinet shell, on the one hand be easy to cause new failure；On the one hand a large amount of manpower and material resources are expended.
Utility model content
The purpose of the utility model is to provide a kind of high-voltage electricity PT fuse withdrawing devices, its advantage is that: reduce maintenance people
Member takes out the difficulty of the fuse of failure PT out of cabinet shell, time saving and energy saving；It also reduces and equipment is made simultaneously in cargo handling process
The possibility of the failure of Cheng Xin.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of high-voltage electricity PT fuse

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of high-voltage electricity PT fuse withdrawing device, with reference to Fig. 1, including the PT fuse in cabinet shell 1
2(Fig. 2).PT fuse 2 extends extension block 3 close to the outer peripheral edge of the end of the one end in 1 outside of cabinet shell, and extension block 3 extends
To cabinet shell 1 outside and be threaded on the outer wall of cabinet shell 1 by the first fixing bolt 4 so that PT is molten
The one end for the cabinet shell 1 that silk 2 extends is fixed on the lateral wall of cabinet shell 1.
With reference to Fig. 1, the outside of cabinet shell 1 is equipped with the stress support 6 of Contraband shape, the end of 6 open end of stress support of Contraband shape
Portion and the outer wall of cabinet shell 1 are inconsistent, and the outside of cabinet shell 1 is equipped with second fixing bolt 5, the second fixing bolt 5
It is fed through the center of the side of stress support 6 along its length, the second fixing bolt 5 is welded far from one end of stress support 6
It is connected to rotation hand wheel 11, the bolt head and PT fuse 2 of the second fixing bolt 5 towards one end of PT fuse 2(Fig. 2) extend cabinet
The end of the side of shell 1 is connected.When the PT fuse 2 in cabinet shell 1 breaks down by long-term use, operator is first
First fixing bolt 4 is removed from extension block 3, then operator uses a hand rotation rotation hand wheel 11 again, and uses another
The stress support 6 of Contraband shape is pinned conflict on the lateral wall of cabinet shell 1 by hand, so that the second fixing bolt 5 is directed away from machine
The direction of cabinet shell 1 is mobile, and PT fuse 2 quickly is affected out out of cabinet shell 1, and then operator is to PT fuse 2
It carries out overhauling or replacing with into cabinet shell 1 new PT fuse 2.
With reference to Fig. 1, in this process, operator rotates the second fixing bolt 5 by rotation rotation hand wheel 11, so that
Second fixing bolt 5 helically formula be directed away from cabinet shell 1 direction it is mobile to by PT fuse 2(Fig. 2) from cabinet shell 1
Interior taking-up.The moving direction of the air pressure resistance generated between PT fuse 2 and cabinet shell 1 in such a way that rotation is advanced offsets
It is anti-, so that the movement routine generated when the second fixing bolt 5 of rotation increases, to form laborsaving lever, it is convenient for operator by PT
Fuse 2 takes out out of cabinet shell 1, saves manpower.
Referring to figs. 2 and 3, PT fuse 2 towards the side of stress support 6 be equipped with Contraband shape ironware 7, Contraband shape ironware 7 far from by
Power bracket 6, the side of PT fuse 2 towards stress support 6 are threaded with third fixing bolt 8, and Contraband shape ironware 7 is along open end
The center of side wall offers through-hole 9, and the through-hole 9 that third fixing bolt 8 is fed through on Contraband shape ironware 7 simultaneously makes Contraband shape ironware
7 is inconsistent with PT fuse 2.Second fixing bolt 5 is fed through Contraband shape ironware 7 along open end far from third fixing bolt 8 respectively
On side wall, and the position that the second fixing bolt 5 is worn is located at Contraband shape ironware 7 along the center of the side wall of open end.It sets in this way
It is equipped with and is conducive to stress balance on Contraband shape ironware 7, and the bolt head of the second fixing bolt 5 and third fixing bolt 8 is located at
The inside of Contraband shape ironware 7.
Referring to figs. 2 and 3, when the second fixing bolt 5 is directed away from the side of cabinet shell 1 under the drive of rotation hand wheel 11
To when movement, Contraband shape ironware 7 affects the direction for being directed away from PT fuse 2 mobile with the second fixing bolt 5 at this time, while Contraband
Shape ironware 7 drives third fixing bolt 8 to be inconjunction with the direction movement that PT fuse 2 is directed away from cabinet shell 1, until PT fuse 2
It is detached from out of cabinet shell 1 completely.Inner peripheral due to Contraband shape ironware 7 along the through-hole 9 of the side wall of open end is bonded with rubber ring
10, the rubber ring 10 of the outer wall and 9 inner peripheral of through-hole of third fixing bolt 8 is inconsistent.The setting of rubber ring 10, increases third
Frictional force between fixing bolt 8 and Contraband shape ironware 7 reduces Contraband during affecting third fixing bolt 8 of Contraband shape ironware 7
Sliding occurs between shape ironware 7 and third fixing bolt 8 so that third fixing bolt 8 rotates on PT fuse 2 makes
Obtain the possibility that third fixing bolt 8 loosens disengaging from PT fuse 2.
Operating procedure: it when equipment is broken down due to PT fuse 2 itself and needs PT fuse 2 from cabinet shell
When taking out in 1, operator first backs out the first fixing bolt 4 from extension block 3, and then operator rotates rotation hand wheel 11,
So that the direction that rotation hand wheel 11 drives the second fixing bolt 5 to be directed away from cabinet shell 1 is mobile, Contraband shape ironware 7 is the at this time
It is mobile towards the direction of stress support 6 under the affecting of two fixing bolts 5, then Contraband shape ironware 7 affect again third fixing bolt 8 with
And PT fuse 2 is directed away from the direction movement of cabinet shell 1, until PT fuse 2 is detached out of cabinet shell 1.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
