Technical field
This application involves field of circuit breakers, and in particular to a kind of mechanical locking structure and mechanical interlocking device of breaker.
Background technique
Vacuum circuit breaker cut-offs appearance as main control indispensable in electric system and protection equipment, high reliablity
Amount is big, the time between overhauls(TBO) is long, it is pollution-free, without series of advantages such as explosion danger, suitable frequent operations, in power industry, work
The every field such as mine enterprise are all more and more widely used.
In the prior art, dual-power transfer switch is a kind of common low-tension switch electric appliance, is widely used in smelting, changes
Work, hospital, government bodies etc. require the occasion of uninterrupted power supply, when common power failure or power failure, dual power supply conversion
Power supply is automatically switched to backup power source by switch, to guarantee normal power supply.But once two breakers close a floodgate simultaneously, then can make
The accidents such as forming apparatus is short-circuit, and personnel are shocked by electricity, it is very dangerous.
As shown in Figure 1, existing breaker 2 ' includes floodgate semiaxis 21 ', energy storage axle 25 ', sincere sub- axis 22 ' and drive shaft
23 ', the floodgate semiaxis 21 ' rigid connection has closing switch 24 ', is arranged fluted 211 ' in the floodgate semiaxis 21 ', described
Rigid connection has sincere sub 27 ' on sincere sub- axis 22 ', and being rigidly connected in the energy storage axle 25 ' has cam 28 ', in the drive shaft 23 '
Rigid connection has connecting lever element 29 '.Before combined floodgate, described sincere sub 27 ' rely on the outer peripheral surface of floodgate semiaxis 21 ' at least partially
On, the sincere sub 27 ' limit cam 28 '.When needing to close a floodgate to breaker 2 ', closing switch 24 ', the combined floodgate are pressed
Semiaxis 21 ' rotates with it, and the groove 211 ' in floodgate semiaxis 21 ' also rotates with it, when groove 211 ' turns to certain position,
The described sincere sub 27 ' parts for relying on floodgate semiaxis 21 ' can be turned over from groove 211 ', after described sincere sub 27 ' rotation, institute
The position-limiting action that cam 28 ' is no longer influenced by sincere sub 27 ' is stated, energy storage device (not shown) can drive energy storage axle 25 ' to rotate, institute
It states cam 28 ' to rotate with it, when the cam 28 ' moves to 29 ' position of connecting lever element, promotion connecting lever element 29 ' is rotated, described
Connecting lever element 29 ' drives drive shaft 23 ' to rotate, and the drive shaft 23 ' drives the dynamic touching in vacuum extinction room by connection structure
Head is moved towards the direction close to static contact, until and static contact contact.
General mechanical interlocks is usually used between the breaker that two mutually cooperate, with the shape of a breaker
State limits the operation of another breaker.Hawser mechanical interlocks is had, in the prior art for preventing two open circuits
Device is in "on" position simultaneously, to avoid the safety accidents such as equipment is short-circuit, personnel are shocked by electricity.
Mechanical interlocks in the prior art is the release lever for making that breaker being interlocked by the pulling of hawser
In lower position, to keep its closing operation invalid.This pulling can fail in the case where there: holding screw is not tightened
To defined torque；Because of holding screw as defined in unselected, and make it using can fluff shortly after；User has selected the cable of substitution
Rope, but the hawser is broken soon after putting into operation.
Application No. is the utility model patent of CN201420742272.4 disclose it is a kind of for it is middle pressure dual power supply switching
Vacuum circuit-breaker handcart, and the first breaker closing is specifically disclosed, operation axis drives first rotating shaft rotation, to drive solid
The the first cam rotation being located in first rotating shaft depresses first chain point of column by the first cam and drives the second interlocking that column is divided to push
It falls in the second groove of second cam, is connected to the first elastic component compressed energy-storage and first of interlocking column lower end at the same time
The outer circle contact of cam is divided on column in first interlocking, prevent the operation axis of the second breaker is from rotating (because of interlocking column
Can only slide axially, not be able to rotate along it), i.e., the second breaker cannot close a floodgate.Above-mentioned mechanical locking structure is complex, and
It is high to the processing request of part, it needs to accurately control cam and interlocks the positional relationship of column, be otherwise difficult to reach control effect.
Therefore, there is an urgent need in the art to a kind of structures simply, the mechanical interlocking structure of operation is facilitated to control breaker, from
And greatly improve the security performance of product.

122 is hinged.It is connected between the drive shaft 23 and connecting lever 13 by shaft coupling 15, the drive shaft 23 is close to one end of connecting lever 13
It is fixedly connected with the first half a coupler 151, the connecting lever 13 is fixedly connected with the second half close to the first half a coupler 151 on one side
Shaft coupling 152,152 cooperating of first half a coupler 151 and the second half a coupler.
For the ease of installation, the specific structure of the shaft coupling 15 of the present embodiment is as follows: first half a coupler 151 includes
First convex block, second half a coupler include the second convex block, and the shape of first convex block and the second convex block can freely be set
It sets, as long as transmission effect can be reached.Due to that can exist and first install two in the use process of the mechanical locking structure
Breaker, rear the case where installing mechanical locking structure, in order to facilitate the installation of, it is this that first convex block may be configured as linear type
The shape that thickness is kept constant may be alternatively provided as the shape that other thickness are gradually incremented by, such as trapezoidal column etc..Second convex block
Shape and the first convex block shape be adapted, when the shape of first convex block be trapezoidal column when, second convex block can be set
Be set to two, the adaptable structure of the medial surface of two the second convex blocks and two opposite sides of trapezoidal column, such as in order to it is trapezoidal
The two sides of column are adapted, and two medial surfaces are arranged and constitute splayed.In order to easy to process, the application preferably the first convex block and
Two convex blocks are linear type convex block, and the second number of slugs is two, and two the second convex blocks are parallel and are oppositely arranged, and described the
One convex block gos deep among two the second convex blocks.In addition to this, in separating brake, " one " of the first convex block and the second convex block is rationally set
Font convex block is respectively positioned on horizontality, convenient when two breakers are in gate-dividing state, takes out intermediate mechanical chain knot
Structure, and then conveniently mechanical locking structure and breaker are overhauled respectively.
The working principle of the shaft coupling of the present embodiment are as follows: " one " of the first half a coupler 151 after linkage structure installs
Realize that power transmits when font convex block accesses among two parallel lugs of second half a coupler 152, under gate-dividing state, institute
