Abstract
The invention relates to a drive for circuit breakers forming part of a circuit breaking system, especially an air-insulated intermediate voltage circuit breaking system, consisting of vacuum circuit breakers which are disposed in a plug-in disconnector unit. The vacuum circuit breakers are integral with the pole module which can be displaced by a disconnector drive so that disconnection can occur. The breaker mechanism is provided with a controllable drive shaft, whereby the rotational displacement thereof is transmitted by drive levers to a radially displaceable control shaft which is connected to a number of horizontally displaceable push rods corresponding to the number of phases which are to be switched. Each push rod vertically displaces a respectively displaceable contact element of the vacuum circuit breaker by means of an articulated lever which is mounted at a fixed pivoting point. The push rods (SS... ) are arranged behind each other in between the drive levers (MH... ) of the control shaft (SW...) in such a way that the control shaft (SW) is alternately subjected to the effects of traction and pressure or vice versa when the displaceable contact elements of the vacuum circuit breaker (VS ) are switched, whereby the tubular drive plane (R3) is offset at an angle of 90 DEG with respect to the plane of the pole module (PE).
Description
The present invention relates to a kind of disconnect equipment that is used for, the drive unit of the circuit breaker in the especially air-insulated medium voltage switchgear equipment, this medium voltage switchgear equipment has the vacuum circuit-breaker that is arranged in the plug-in type Disconnecting switch unit (Trenneinschub), wherein, vacuum circuit-breaker is assembled in the pole module (Polmodul), this pole module is removable by an isolating switch drive unit for realizing isolation features, at this, driving mechanism for switch is equipped with a controllable driving shaft, the yaw motion of this driving shaft passes to a radially deflectable Control Shaft by the drive link in two extreme positions of isolating switch, this Control Shaft is counted the deflectable push rod of corresponding horizontal with quantity and the phase line that remains to be connected and is connected, wherein, every push rod makes vacuum circuit-breaker removable contact component vertical moving separately by a hinged lever that is bearing on the fixing point of rotation.
The circuit breaker of the above-mentioned type is open by German patent application DE 197 53 177 with drive unit.All push rods that are used in the pole module of circuit breaker drive removable contact component are by the driving shaft control of attaching troops to a unit jointly, and this driving shaft is connected with power transfer mode with two drive links.Drive link with the opposed zone of driving shaft in have (control) control lever shaft that is connected with power transfer mode equally with drive link, by it, the yaw motion of driving shaft converts the horizontal deflection campaign of control lever shaft to.Along with the horizontal deflection of control lever shaft, push rod corresponding deflection and with the hinged lever of rotatable supporting makes contact deflection.Necessary power conversion must simultaneously and accurately pass to moving contact to the switching process of vacuum circuit-breaker.But can repeatedly reappear under the situation that switching operation must cause time course to change in the requirement of satisfying relevant reliability and life-span and can be in the contact force of determining the time.
Technical problem to be solved by this invention is, a kind of structural design scheme that is used for pole module of circuit breaker is provided, and has the reliably on/off operation of long-life while to realize circuit breaker.
Above-mentioned technical problem of the present invention solves by following feature:
1.1 described vacuum circuit-breaker on a common pipe transmission plane (Roehrenantriebsebene) but in Be Controlled,
1.2 described pole module on a common pole module transmission plane (Polmodulantriebsebene) but in Be Controlled,
1.3 described pipe transmission plane is with respect to pole module transmission plane at an angle of 90,
1.4 described push rod is provided with before and after between the drive link of Control Shaft so in turn, makes when the moving contact of on/off operation vacuum circuit-breaker, alternately form to one of Control Shaft draw, a compression or is pressed, a tension stress.
Utilize and be in the right angle setting between pipe transmission plane and the pole module transmission plane and make push rod front and back between drive link that the load of average all push rods best is set.This not only plays positive role to realization make-break operation simultaneously moving contact, and to also playing positive role the useful life of improving vacuum circuit-breaker.Simultaneously, can make pole module of circuit breaker that compact structure is arranged, and can adopt simple structural design means by such layout, realize vacuum circuit-breaker be finish its isolation features the mobility that should possess.
Also comprise following characteristics according to an optimal way of the present invention:
2.1 described hinged lever under the control action of an original contact stage clip, makes the tension force of contact stage clip be effective as contact pressure when connecting the moving contact of vacuum circuit-breaker.
The contact stage clip is not in the power accelerating chain stronger between pipeline connecting rod and the driving shaft.In addition, based on the conversion of described spring force, can adopt a spring that bulk is less.
Also comprise following characteristics according to another optimal way of the present invention:
3.1 the moving contact of vacuum circuit-breaker prolongs by a pipeline connecting rod, the free end of this pipeline connecting rod is connected with power transfer mode with corresponding push rod by corresponding hinged lever with meeting at right angles.
By changing the connecting rod of extension, the contact travel of vacuum circuit-breaker simply mode adapts to required situation.
The present invention is described in detail by three execution modes shown in the drawings below, in the accompanying drawing:
Fig. 1 is the three-dimensional view of pole module of circuit breaker, and this pole module has important for the present invention driver part;
