Definitions
- the invention relates to drive devices for interrupter units of switchgear for power supply and distribution, in particular for vacuum circuit breakers of medium-voltage switchgear, with lever arrangements controllable by means of solenoid drives for actuating the movable contact parts of the switchgear by means of coupling rods, each of the switchgear having at least one pole part and one drive part is equipped and each solenoid drive has a movable armature as well as a closing coil and a closing coil.
- the conventional spring-loaded drives for the interrupter units which are formed from a large number of mechanical individual elements, are here by
- the movable contact part of the interrupter unit - here designed as a circuit breaker within a vacuum chamber - is vertically deflected via a so-called coupling rod, the coupling rod being connected to a lever shaft coupled by the magnetic drive Lever shaft is connected at one end to the coupling rod of the interrupter unit, while the other end of the coupling rod is also controlled by the armature of the magnetic drive
- the lifting force of the magnetic drive for actuating the movable contact part of the interrupter unit becomes So deflected by means of the lever shaft such that within the 2 interrupter unit again a deflection in the vertical direction.
- the magnetic drive has a switch-on coil and a switch-off coil, the switch-on coil and the switch-off coil only being used for switching, while the generation of the holding forces is achieved solely by the permanent magnets.
- the object on which the invention is based is to improve the known magnetic drive devices for the interrupter units in terms of construction and to significantly simplify them kinematically and, moreover, to design the interrupter units themselves as a compact functional unit.
- lever arrangements are an integral part of the linear motor drives
- the linear motor drives can be influenced in each case by a control unit which optimizes the movement sequences of the switching processes that are relevant to the switching physics,
- each linear motor drive is controlled via a mains connection.
- linear motor drives for the interrupter units, force redirection is no longer required to control the moving contact parts.
- the linear motor drives thus provide 3 are very simple drive means that easily meet the high demands in this technology with regard to greater reliability with a correspondingly high switching frequency. With the simple linearly acting power transmission, the design expenditure compared to the previously known drive devices is limited to a minimum.
- linear motor drives are realized by three-phase linear motors
- the three-phase linear motors are formed from thrust force and movement stroke determining individual components, 2.3 the individual components are realized by the number of motor coils and / or by the number of motor modules operated in parallel.
- the interrupter units can be designed as compact components which are known to be manufactured with a correspondingly small volume in the gas space filled with insulating gas or air, for example. 4 A further advantageous embodiment of the invention sees the features
- FIG. 1 showing an interruption unit with three vacuum switches that are controlled by a common linear drive
- FIG. 2 this interrupter unit together with one
- FIG. 1 shows the interrupter unit UE with three vacuum switches, the movable contact parts of which are actuated by the linear motor drive LA in the movement stroke marked by the arrow by means of the common lever arrangement HA. Furthermore, it is indicated that the linear motor drive LA is realized by the three-phase linear motor DL, the movement stroke of which directly effects the actuation of the lever arrangement HA from the motor coils MS. Depending on the required thrust and the required movement stroke, the number of motor coils MS and / or the number of motor modules MM can be adapted accordingly in the linear motor drive.
- the linear motor drive LA is connected to the control unit SE, with which the movement sequences relevant to the switching physics of the movable contact parts of the interrupter units UE can be optimally controlled.
- FIG. 2 shows a further exemplary embodiment of the invention, in which the interrupter unit UE is accommodated together with the three-phase linear motor DL and the control unit SE in the gas space GR.
- the necessary network connection NA for the control unit is led directly into the gas space GR by means of a known gas-tight bushing, not shown.
- the individual components in the gas space GR can be of correspondingly smaller dimensions in order to implement the same performance requirements.
- FIG. 3 provides a further merging of the individual components of the interrupter unit UE, in which the linear motor drive LA with the
- Control unit SE are housed directly in the vacuum switch.
- the required mains connection NA is led into the interior of the vacuum switch by means of a gas-tight bushing.
