Background technology
The task of electric switch equipment, such as chopper is, when specific interference so that multiple load and power supply network
Depart from.Common interference is the appearance of short circuit current, and chopper is generally designed to, in the case of this short circuit current
Make switch element motion and hence in so that connection decoupling between load and electrical network.
The present invention relates to a kind of electric switch equipment, the chopper particularly in low voltage range." low-voltage " typical case
Refer to until about 1000 volts of voltage.The structural accordingly design of the separate section of circuit can be this to be also used for exceeding
1000 volts, for example until 6.3kv switching voltage switching device.Especially, this electric switch equipment, such as low-voltage open circuit
Device is designed under overcurrent situations and/or cuts off current path in a short-circuit situation.They can be designed as one pole or
Multipole, particularly three poles.
Electric switch equipment is usually placed in switch cubicle, to protect this electric switch equipment.Generally, this switch cubicle
It is arranged in the region of machine, it is controlled by the electronics internal mechanism (innenleben) of switch cubicle.So that without awarding
Power personnel can not touch electric switch equipment it is known that being designed as cabinet door lockable.In order to switch on and off electricity
Air cock equipment, this electric switch equipment has driving means.That is, drive arrangement on electric switch equipment simultaneously
And enable to switch on and off electric switch equipment.Especially, here applies and can transport between on-position and open position
The dynamic, driving means for being switched on or switched off electric switch equipment.
For example there is known direct drive unit as driving means, the couplet on the door connects rotating driving device, side wall rotation driving dress
Put and motor drive.In order to protect personnel it is known that rotation driving for electric switch equipment, such as low voltage switch equipment
The mechanical door locking device of device.Here, mechanical door locking device one as direct drive unit in direct drive unit
Ingredient realize, it is as the part of electric switch equipment.Connect in rotating driving device in the couplet on the door, mechanical door locking device is made
For the ingredient of the one of connection element, to realize for the axle of handle.There is no machinery known to the wall rotating driving device of side
Door lock assembly.
In known mechanical door locking device for driving means disadvantageously, it is very inflexible and depends on
Electric switch equipment.
Content of the invention
The purpose of the present invention is: eliminates the known machine door of the driving means for electric switch equipment at least in part
The aforesaid drawbacks of locking device.Especially, the purpose of the present invention is: realizes a kind of flexible and unrelated with electric switch equipment
Mechanical door locking device.
Described purpose according to the present invention by a kind of have according to claim 1 the mechanical door locking device of feature and
Realized by a kind of locking unit with feature according to claim 6.Other features of the present invention and details by
Draw in dependent claims, specification and drawings.Here, the spy of the description that combines with according to the mechanical door locking device of the present invention
Levy and be of course also apply to combine with according to the locking unit of the present invention and vice versa respectively, thus single with regard to each
The disclosure of inventive aspect all the time reciprocally with reference to or can reciprocally reference.
According to the first aspect of the invention, described purpose passes through a kind of at least one driving dress for electric switch equipment
Realizing, this electric switch equipment is arranged in switch cubicle the mechanical door locking device put, and this switch cubicle can be by movingly cloth
The cabinet door put on the doorframe of switch cubicle carrys out locking.Mechanical door locking device is characterised by, this mechanical door locking device has
Gate cell for the doorframe unit that is fixed on doorframe with for being fixed on cabinet door, wherein doorframe unit has and can transport
Dynamic latch, this latch designs in the following manner: latch is joined to gate cell for latch switch cabinet door in locked position of coupler
Receiving portion in and remove from the receiving portion of gate cell to open cabinet door in unlocked position.Additionally, in machine
It is designed as in tool door lock assembly, in order that latch moves between locked position of coupler and unlocked position, Bao is arranged on doorframe unit
Step on the first end of line, the wherein the second end of Bowden cable can with least one driving means effect of electric switch equipment even
Connect.
The mechanical door locking device of so driving means for electric switch equipment of design can be extremely flexibly using simultaneously
