Description
Technical field
The utility model belongs to a kind of disconnecting switch, and in particular to a kind of heavy current disconnecting switches of high reliability.
Background technology
Present heavy current disconnecting switches are in the majority with guillotine type.Such as figure (1) and figure (2).
Electric current flows to contact knife component from contact and finally flows to touch base.Since electric current is larger, copper bar is thicker, easily leads to and copper bar
Being formed during overlap joint forces connection to cause contact deflection.And contact deflection is little by little, contact can be caused to be contacted with contact knife bad, can caused
Switch fever is even burnt.
Switch separating brake, combined floodgate are to promote main shaft rotation to drive rod assembly to rotate by operating mechanism, finally promote contact knife
Component is rotated to realize separating brake, close a floodgate.And the sliding block of rod assembly front end is straight with link insulator front end riveting thread head
Connect and be connected through a screw thread.There are gap certainly between link insulator front end riveting screw thread head thread and sliding block internal thread.More
Screw thread can be damaged or even slide tooth in secondary separating brake, making process.
Two contact knife rear portions of contact knife component are connected with touch base, be utilize through bolt pass through bearing saddle bore formed supporting
Point.Meanwhile there is compression spring to push contact knife component to two outsides in non-locking state open in bearing block both sides.Contact knife forward portion
And one positioning sleeve when closing a floodgate in the medium design through bolt.Also there is compression spring in set both sides, contact knife is in non-lock
Also it is pushed under tight state.Contact knife is all pushed in open position to closing position.I.e. contact knife component is with touching
There is gap between seat (head).Meanwhile there is gap between bearing block and the bolt that passes through.In this way, contact knife component can divide, close
It can be rocked during lock.Equally, contact knife supporting hole and also there is gap through bolt.Contact knife component is also resulted in divide, closing
Rocked during lock.Rock it is final will result in contact knife deflection formed during divide-shut brake, contact knife is with touching in making process
Easily contact knife is caused to rest on contact during head contact.Switch is caused to lock or can not close a floodgate in advance.
Contact knife component separating brake is only hauled after in place by rod assembly, since electric current substantially contact knife is made big, final contact knife
It is too heavy.After separating brake, contact knife is still separated downwards due to dead weight, damage switch.
Utility model content
The utility model proposes a kind of heavy current disconnecting switches of high reliability regarding to the issue above, its is compact-sized,
Simple and convenient, dependable performance is installed.
Specific technical solution is as follows：
A kind of heavy current disconnecting switches of high reliability, including contact, touch base, contact knife component, main shaft and rod assembly, are touched
Seat is equipped with bearing block, and bearing block is equipped with support holes, and contact and touch base are oppositely arranged, main shaft between contact and touch base,
Rod assembly one end is connected with main shaft, the other end is connected with contact knife component, and contact knife module back is passed through by bolt
Support holes are arranged on bearing block, contact knife component is rotated centered on bolt, by the rotation of contact knife component, are touched
Knife assembly is anterior to realize folding, the contact surface structure in the arc-shaped of contact and contact knife forward portion between contact；
The bearing block is equipped with only hook bolt, and only bolt is locked in support holes by hook bolt through bearing block
In, passed through on contact knife component and bushing is equipped with the supporting hole of bolt, bushing is coated on outside bolt and bushing and supporting spiral shell
Transition coordinates between bolt, and resetting spring is equipped between bearing block and contact knife component both sides, and resetting spring cladding is arranged on bushing
Outside, the length of the bushing are more than the thickness of contact knife.
A kind of heavy current disconnecting switches of above-mentioned high reliability, wherein, the rod assembly includes link insulator, commutation
Pull rod and sliding block, commutation pull rod is radially fixed on main shaft, and link insulator is fixed on commutation pull rod by the way that axis pin is rotatable
One end, rivets thread head on the link insulator other end, and thread head is fixed by nut check again after being threadedly coupled with sliding block, sliding
Block is fixed on contact knife component.
A kind of heavy current disconnecting switches of above-mentioned high reliability, wherein, the touch base is equipped with caging bolt, with bearing block
Spacer pin is equipped between connected contact knife, cooperating between spacer pin and caging bolt, it is spacing to realize.
The beneficial effects of the utility model are：
(1) high-current switch electric current flows to contact knife component from contact and flows into touch base outflow, and it is easy that contact overlaps thicker copper bar
The contact surface of deflection, contact and contact knife uses arc-shaped structure, even if there is contact deflection, contact knife is that line connects with contact circular arc
Touch, still do not influence conduction.
(2) nut check is used after being threadedly coupled between link insulator front end riveting thread head and sliding block, eliminates pull rod riveting
The gap of screw thread between thread head and sliding block threaded hole is connect, is not in thread damage in switch point, combined floodgate.
(3) after switch debugging is good, increases an only hook bolt on bearing block, allow the bolt through bearing block to abut against axis
On bearing inner hole wall, it can not rotate, its gap is eliminated.Increase bushing, liner sleeve length in supporting hole of the contact knife through bolt
It is longer than contact knife thickness much to be coordinated between bushing endoporus and bolt using transition, add the stability of contact knife component.Also finally
Contact knife is withstood with resetting spring.In this way, contact knife will not rock.
(4) contact knife component is overweight, props up spacer pin with caging bolt afterwards in place in separating brake, contact knife component will not fall.
