Description
Technical field
The invention belongs to ring main unit double circuit power supply interlock protection technical field, more particularly to a kind of it is used in ring main unit
The procedure lock interlock of F cabinets.
Background technology
In present distribution network systems, to improve power supply reliability and stability, double-power supply loop power supply is much employed, when one
When individual power-supply system breaks down, the power supply of another power-supply system can be quickly switched into, guarantee does not power off.
In power system, two power-supply systems are because certain difference be present in frequency, voltage, electric current, power factor (PF), no
Allow the power supply that is directly cascaded.During normal power supply, only a power-supply system plays a role, and another power-supply system is made
For stand-by power supply.This just needs to add blocking device among two power-supply systems, to ensure that synchronization only has a power supply
System provides power supply.
In existing ring main unit, L cabinets and V cabinet-type air conditioners structure carry procedure lock blocking function, when can realize dual power supply
Blocking function, i.e., synchronization only has an inlet wire L cabinet to close a floodgate, and another inlet wire L cabinet can not operate.
And F cabinets as inlet wire when, there is presently no procedure lock interlocking, for making the ring main unit of power supply entering line with F cabinets and
Speech, it is clear that the reliability requirement of power supply can not be met.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of ring main unit procedure lock interlocking dress
Put, F cabinet-type air conditioner structure procedure lock interlock protections can be realized, improve the power supply reliability of product.
The purpose of the present invention is completed by following technical solution, and this ring main unit procedure lock interlock includes connection
Latch mechanism, the procedure lock for inserting key, described procedure lock be arranged on interlocking mechanism front end face, the side of the procedure lock with
Locking plate is in contact, and the locking plate is slidably connected on cabinet, and the opposite side of procedure lock is in contact with the front end of interlocking mechanism；Institute
The rearward-facing end of the interlocking mechanism stated is provided with energy-stored spring, is abutted against after energy-stored spring energy storage in interlocking mechanism.
Preferably, the both sides of described procedure lock are respectively equipped with left tapered end, right tapered end, the front of procedure lock, which is provided with, to be used
In the jack for inserting key.
Preferably, the left tapered end of described procedure lock is resisted against the front of interlocking mechanism after energy-stored spring energy storage
Side.
Preferably, the right tapered end of described procedure lock is in contact after procedure lock opening with locking plate, and pass through interlocking
Piece stops the rotation of operating shaft.
Preferably, described interlocking mechanism includes guide rod, fixed block, described guide rod one end is fixed on fixed block
On, and the guide rod other end is in contact with energy-stored spring, procedure lock is arranged on the fixed block, and the left tapered end of procedure lock
It is in contact with fixed block.
Beneficial effects of the present invention are：When occurring in power system scheme by the use of F cabinets as power supply entering line cabinet, pass through connection
The mutual cooperation of latch mechanism and procedure lock and composition two lock a key inter lock, using two one key schemes of lock, synchronization,
Only a key can use, when also ensuring that dual power supply, can only power transmission all the way, can not be grasped all the way in addition
Make, ensure the safety and reliability of power supply.
Brief description of the drawings
Fig. 1 is the F cabinet-type air conditioners structure and interlock mounting structure schematic diagram of the present invention.

Label in accompanying drawing is respectively：1st, interlocking mechanism；2nd, procedure lock；3rd, locking plate；4th, cabinet；5th, energy-stored spring；6、
Operating shaft；11st, guide rod；12nd, fixed block；21st, left tapered end；22nd, right tapered end；23rd, jack.
Embodiment
Below in conjunction with accompanying drawing, 1,2 couple of present invention does detailed introduction：The present invention includes interlocking mechanism 1, for inserting key
Procedure lock 2, described procedure lock 2 be arranged on interlocking mechanism 1 front end face, the side of the procedure lock 2 connects with locking plate 3
Touch, the locking plate 3 is slidably connected on cabinet 4, and the opposite side of procedure lock 2 is in contact with the front end of interlocking mechanism 1；Described connection
The rearward-facing end of latch mechanism 1 is provided with energy-stored spring 5, is abutted against after the energy storage of energy-stored spring 5 in interlocking mechanism 1.
The both sides of described procedure lock 2 are respectively equipped with left tapered end 21, right tapered end 22, and the front of procedure lock 2, which is provided with, to be used for
Insert the jack 23 of key.
The left tapered end 21 of described procedure lock 2 is resisted against the front end side of interlocking mechanism 1 after the energy storage of energy-stored spring 5.
The right tapered end 22 of described procedure lock 2 is in contact after the opening of procedure lock 2 with locking plate 3, and is hindered by locking plate 3
Keep off the rotation of operating shaft 6.
Described interlocking mechanism 1 includes guide rod 11, fixed block 12, and described one end of guide rod 11 is fixed on fixed block 12
On, and the other end of guide rod 11 is in contact with energy-stored spring 5, procedure lock 2 is arranged on the fixed block 12, and procedure lock 2
Left tapered end 21 be in contact with fixed block 12.
The present invention operation principle be：Procedure lock 2 is bolted on the front end face of interlocking mechanism 1, extracts key
Operation sequence lock 2 is locked, and the right tapered end 22 of procedure lock 2 promotes locking plate 3, to realize the stop to operating shaft 6, prevents F machines
The operation of structure；
When procedure lock 2 is opened with key, F cabinet-type air conditioners structure can normal energy storage, and carry out on/off switch operation, and key is
It can not pull out；
Because the left tapered end 21 of procedure lock 2 connects with interlocking mechanism 1, after mechanism energy storage, energy-stored spring 5 is close to
Left tapered end 21 withstands in interlocking mechanism 1, interlocking mechanism 1, and now key can not be extracted；
So, synchronization is ensure that from mechanically actuated, only when a key opens procedure lock, F cabinet-type air conditioners structure is
Can be operated, ensure that double-power supply loop power supply when, synchronization only all the way inlet wire can operate, in addition primary Ioops without
Method operates, and ensure that the reliability of power supply.
It is understood that it will be understood by those skilled in the art that technical scheme and inventive concept are subject to
The protection domain of appended claims of the invention should all be belonged to replacement or change.
