Description
Technical field
The invention belongs to low-voltage distribution system interlock design fields, are specifically related to a kind of breaker interlocking
Device and a kind of breaker group with the interlock.
Background technique
Power supply-distribution system is one of core content of electrical design, even if high voltage power supply is derived from same bus section, busbar section, in order to limit
System short circuit capacity processed prevents parallel operation of transformers, is also required to be interlocked between transformer low voltage bus section, busbar section.Therefore, exist
After power supply and load determine, the interlock method of low-voltage distribution system becomes an important factor for influencing system wiring scheme.
Interlock method is generally divided into two class of electric interlock and mechanical interlocking.It is connected and is realized by breaker secondary control loop
Interlock is common electric interlock mode, and primary system scheme is flexible, and secondary connection scheme is mature, but is interlocked reliable
Safety often cannot get the approval of power supply department not as good as mechanical interlocking mode, simple electrical interlocking system.It applies in recent years
Universal all kinds of intelligent universal low-voltage circuit breakers all provide mechanical interlocking function, but due to recognizing not mechanical interlocking at present
Enough abundant, low-voltage circuit breaker mechanical interlocking will appear the various requirements being unable to satisfy in the application.Omnipotent breaker machinery connection
Latch mechanism is divided into two classes: one kind be for prevent breaker itself close a floodgate operation mechanical locking, such device have prevent
The safety lock and padlock of crank hole, sealing cover or safety lock on mechanical switch knob are opened, mechanical separating brake is pressed with electrical combined floodgate
Locking device etc. on button, by locking the switch knob of circuit breaker operation mechanism, to reach the requirement that cannot be closed a floodgate；It is another kind of
It is the mutual mechanical interlocks of omnipotent breaker, suitable for the mechanical interlocking between two or three breakers, interlocking dress
It sets using circuit breaker operation mechanism and reaches requirement, sub-lever interlocks firmly and the soft interlock of wirerope；Wherein lever interlocks dress firmly
It sets commonly used in three right angle setting breakers, such as two breakers interlockings need to only remove a breaker for end, between breaker
Being arranged vertically occasion necessarily requires installation vertical range between breaker no more than 90cm, is difficult in this way or cannot achieve three
Any interlocking between breaker, use occasion is opposite to be limited to, poor universality.
The low-voltage distribution mode among two-way power supply power supply for busbar breaker is widely used in low-voltage distribution system, needs
It wants to realize mechanical interlocking between three breakers, it is required that are as follows: one or two breakers can be arbitrarily closed, when closing two
After breaker, third platform circuit breaker lock cannot close a floodgate.In three circuit breaker interlocking devices, using any interlock
The both ends of drive connecting rod are all connect with one end of the follower lever on other two switch interlocking devices with wirerope, realize separating brake and conjunction
The mechanical interlocking of lock controls；In its circuit breaker interlocking device, follower lever and driven shaft are an entirety, as long as driven shaft is drawn
The trip shaft on interlock is pushed down in rotation, locks the driving shaft of this TV station switch, then this TV station switch can not just close a floodgate；The operation
Mode is high to device required precision, it is easy to the problem of interlock failure, poor reliability occurs.
Through retrieving, license notification number is the Chinese patent of CN102664112, discloses a kind of machine for breaker
Tool interlock, this application include three interlocking units being connected with three circuit breaker transmission devices, between each interlocking unit
Pass through transmission hawser connection.Each interlocking unit by bracket, baffle, movable pulley, lower lever, upper lever, first back-moving spring,
Second back-moving spring, adjusting block, upper shift plate, set aside board group at.The device drives upper lever using the rotation of interlocking unit movable pulley
It turns an angle, when upper lever rotational angle range reaches the angle for acting emergency brake-dividing device, is then interlocked with this single
The emergency brake-dividing device movement of the connected breaker of member, this breaker can not close a floodgate；When any two of them interlocking unit connects
The breaker closing connect, then the switching signal of the two interlocking units drives the movable pulley rotation of third interlocking unit, so that
Upper lever rotational angle reaches the angle for acting emergency brake-dividing device, to realize any two breaker closings, then third
Breaker cannot close a floodgate, which has structure simple, tear tune open and facilitate advantage, but being reached by angular range makes emergency opening
The implementation method of the angle of device action will appear angle in the actual operation process and grasp difficult, poor reliability, safety difference
Disadvantage and device assembly precision is required high.
Summary of the invention
Goal of the invention: high, existing to the requirement of device assembly precision when in order to overcome three breaker interlockings in the prior art
The problem of interlock poor reliability, safety difference, the present invention provide a kind of breaker interlock, interlock safety
Property, high reliablity, stability are good；The interlock requirement between three breakers, strong applicability can at least be met；And it operates and debugs
Convenient, convenient disassembly is flexible；The breaker group with interlock that the present invention provides a kind of simultaneously, the breaker group guarantee
At least a breaker is in gate-dividing state in use process, and strong applicability is with good expansibility, and can satisfy reality
To the different demands of product interlocking in the application of border.
