Description
Technical field
The utility model is related to interlock technical field, more particularly to a kind of switch-cabinet grounding mechanism across screen interlocking dress
Put.
Background technology
Required according to standard, middle-high voltage switch must possess five anti-interlockings, at present routine interlock method there are 3 kinds：Machinery
Interlocking, procedure lock, electric interlock.
Mechanical interlocking is with the mechanical mechanism for conditioning each other and linking between switch cubicle or the operating position of outdoor switch blade
To reach the interlock requirement of priority action.Mechanical interlocking is in operation without using auxiliary operations such as keys, it is possible to achieve
Correctly carrying out with operation order, automatically unlocks step by step.When maloperation occurs, it is possible to achieve automatic interlock, prevent to grasp by mistake
The carrying out made.Mechanical interlocking can realize the interlock requirement of forward and reverse, directly perceived with interlocking, be hardly damaged, service work
Amount is little, the advantages of easy to operate.But mechanical interlocking can only be in the mechanical action dependent part of inside switch cabinet and outdoor switch blade etc.
Apply between position, between two cabinets or between switch cubicle and the outer controller switching equipment of cabinet and between outdoor switch blade and switch (other plug-in strips)
Interlock requirement it is also beyond one's ability to help.So on switch cubicle and outdoor switch blade, can only also need to be aided with other based on mechanical interlocking
Interlocking method, can reach all five anti-requirements.
Procedure lock (or claiming Mechanically programm's lock) is to reach priority unlocking operation with operation sequence transmission or displacement with key
Requirement.Its great advantage is that key transmission is not limited by distance, and procedure lock has in operation the transmission of key and key
The auxiliary movement of spoon number change, meets the requirement of the operation order that unlocking condition is limited in operation order, with regulation in operation order
Track route it is completely the same.But often there is the situation of loss in key transmittance process, skeleton key is also required to especially management.Separately
Outward, the mechanism more for unlocking condition, needs professional to understand operation order, and operating procedure is complicated.
Electric interlock is that the electromagnetic mechanism action by solenoid is operated to realize unlocking, and is being prevented between mistakenly entering into charged
Every interlocking link in be indispensable blocking element.The advantage of electric interlock is easy to operate, without auxiliary movement, but
Following outstanding problem is there is also in installing and using：1. when in general electromagnetic lock is used alone, only unlocking function does not have
There is reverse interlocking function.Need and electric interlocking circuit is used cooperatively and there could be forward and reverse interlock；2. as interlocking unit
The electromagnetic lock structure of part is complicated, and out of doors moisture-sensitive is mould bad for solenoid, and insulating properties are reduced, and increased the failure of straight-flow system
Rate；3. cabling is needed, increases extra construction volume；4. the auxiliary contact for sealing in operating mechanism are needed.It is auxiliary according to operating experience
Contact is helped easily to produce the reliability of loose contact and impact action；5. in the controlling switch of breaker, connection is typically all lacked
Lock measure.
Therefore, routinely all there is a kind of various, new interlock of urgent need in interlocking to three of the above.
