Vacuum interrupter, push rod drive the mechanical movement of the switch contact inside vacuum interrupter.The drive of traditional medium/high voltage breaker
Dynamic device is based on mechanical spring, pneumatically or hydraulically electromagnetism, stored energy mechanism.Particularly in the breaker with mechanical spring driver
In, as component, transmission parts and the electric connector of the function group of energy storage, locking, release and mutual interlocking gear are more or less divided
Cloth is in drive shell body.
The shortcomings that this well-known breaker produces be：
- too many modification, is set without construction set, and great effort spends in logistics, storage, first item inspection etc..
- without rational circuit breaker element it is prefabricated/possibility of test/storage.
- great effort spends in the training and guidance to production and maintenance personal.
Stock's production of the breaker of-a large amount of modification, rather than a small amount of prefabricated drive module.
- production time and of high cost.
- be only linked to a factory driver and breaker production, rather than the flexible production of drive module
Place, then assembles breaker.
It is disclosed in similar to this well-known breaker in such as DE19936986A1.
The content of the invention
It is therefore an object of the present invention to reasonable prefabricated and finally this with arranging with breaker drive module
The compact form of the flexibility of drive module overcomes these shortcomings.
The present invention is implemented with the combinations of features of claim 1.
Further advantageous embodiment is disclosed in the dependent claims.
In order to overcome disadvantages mentioned above and realize above-mentioned purpose, in the present invention, driver is configured to modular event driven device, and
And the modular event driven device is made of combined module so that modular event driven device adapts at least different breaker grades
And pole span.
Mentioned mould above-mentioned function successively in the block is implemented by supporting prefabricated to realize the intention of enhancing manufacture.
In a further advantageous embodiment, driver includes single energy-storage module, lock modules, interlocking module and connection
Device module, they mechanically and are functionally connected with each other successively so that energy-storage module and lock modules are mechanically fastened together
To console, and connector modules are caused to be mechanically connected to interlocking module and energy-storage module.
In a further advantageous embodiment, energy-storage module includes spring and " spring energy-storage " shape for indicating mechanical energy storage
The device of state.Therefore, all these correlation functions referred to and detection function are directly embodied in energy-storage module.
In a further advantageous embodiment, lock modules include mutual interlocking gear, on/off button and for indicating breaker
Switching state ON/OFF indicator.
In a further advantageous embodiment, connector modules include being used for energy storage instruction and/or are controlled for energy storage motor
Toggle switch, and/or auxiliary switch, and/or anti-trip relay and/or circuit breaker drive is connected to switchgear panel
Plug.
In a further advantageous embodiment, auxiliary switch is linked to lock modules via gear segment.Therefore, after assembling not
Need to be adjusted the stroke of auxiliary switch.
In a further advantageous embodiment, energy-storage module is linked to lock modules via main shaft and leverage.
In a further advantageous embodiment, energy-storage module is prefabricated into the modification of the actuating power of different definition, and then
It is placed on release unit for the required actuating power of definition.
Brief description of the drawings
Fig. 1 shows the embodiment of the present invention in view of all critical elements.
Embodiment
The essential characteristic of the present invention is the modular event driven device established for medium voltage breaker.Modularity follows the structure of definition

4.Connector modules 6 are threaded into interlocking module 5 and energy-storage module 3.
Lock modules 4 include the on/off button for switching, ON/OFF indicator, locking and interlocking relieving mechanism.
Connector modules 6 include be used for energy storage indicate and for energy storage motor control toggle switch, auxiliary switch, anti-trip relay with
And breaker is connected to the plug of switchgear panel.Auxiliary switch is linked to lock modules 4 via such as gear segment.
Energy-storage module 3, lock modules 4, interlocking module 5 and connector modules 6 are manufactured and stored independently of each other.
Driver 1 is completed by adding main shaft 7, curve disc 8, lever 9 and coupling bar 10.
Energy-storage module 3 is linked to lock modules 4 via main shaft 7 and leverage.The energy-storage module of adaptation, lock modules
Different breaker types, grade and the requirement of configuration are designed to meet with connector modules and interlocking module.
According to the type and grade of breaker, the different modifications of energy-storage module are designed with by using a variety of spring performances
Spring multilevel energy is provided.
The component of lock modules is designed according to the spring used in energy-storage module.
The modification of connector modules is designed to different boost voltage grades.Interlocking module is designed to inhomogeneity
The switchgear for being equipped with breaker of type.
Therefore, can be by energy-storage module, lock modules, connector mould for the driver with different grades of breaker
The modular system of block and interlocking module forms.
The front view of one typical embodiment of the modular event driven device of the present invention is that energy-storage module is located at lock modules
Right-hand side, and connector modules are located at the top of energy-storage module, and interlocking module is located at the left-hand side of connector modules and closes
The top of lock module.
