Electric switch equipment 10 shown in Figure 1, particularly high-voltage switch gear switchgear.Switchgear 10 has and is separated/the series circuit that forms of earthed switch TE2 be attached thereto second by the first separation/earthed switch TE1, the power switch LS that is attached thereto.
First separation/earthed switch TE1, power switch LS and the second separation/earthed switch TE2 are configured to independently switching device respectively.Power switch LS and/or two separation/earthed switch TE1, TE2 can be arranged in the container of filling with separation gas at this.
Two separation/earthed switches TE1, TE2 have three links 11,12,13 respectively, wherein link 13 ground connection.The link 11 of the first separation/earthed switch TE1 is connected with the first I/O EA1, and on the link 11 of the second separation/earthed switch TE2, is connected with the second I/O EA2.The link 12 of the first separation/earthed switch TE1 is connected with the power switch LS with an one link, and on the link 12 of the second separation/earthed switch TE2, is connected with the power switch LS with its another link.
Each in two separation/earthed switches TE1, TE2 can have following three on off states: two links 11,12 are interconnected; Three links 11,12,13 are not interconnected; Link 11 is connected also therefore ground connection with link 13.These three on off states are separated the/state P21 of earthed switch TE2, P22, P23 hereinafter referred to as the state P11 of the first separation/earthed switch TE1, P12, P13 with second.
Two separation/earthed switches TE1, TE2 and common driving mechanism for switch 15 mechanical couplings.Mechanical couplings is only schematically depicted as arrow 16,17 in FIG respectively.The driving mechanism for switch less than 15 of Fig. 1 further describes by Fig. 2.
Power switch LS is closed and therefore conducting connects or opens and therefore cause interruption.Can by means of the mechanism's Reciprocative switch being only schematically marked as arrow 19 in FIG between two on off states of power switch LS.
Illustrate in greater detail the first embodiment 15 ' of the common driving mechanism for switch 15 for two separation/earthed switches TE1, TE2 in fig. 2.The left side of driving mechanism for switch 15 ' is indicated and to be separated/the mechanical couplings 16 of earthed switch TE1 with first, and indicate on the right side of driving mechanism for switch 15 ' and to be separated/the mechanical couplings 17 of earthed switch TE2 with second.In addition, on off state P11, P12, P13, P21, P22, P23 of two separation/earthed switches TE1, TE2 is indicated in fig. 2, that is respectively with affiliated electric switch symbol.It should be noted that, the switch symbols illustrated only exist for purposes of illustration and must not exist forcibly.
Driving mechanism for switch 15 ' has support 21, maintains motor 22 thereon.Motor 22 has driving shaft 23, this driving shaft carrying cam disc 24.The axis of cam disc 24 and the driving shaft 23 of motor 22 directed coaxially.Therefore cam disc 24 can be rotated along both direction around its axis by motor 22.
In cam disc 24, there are two serpentine track KB1, KB2, described serpentine track is introduced in cam disc 24 in this as recess.First serpentine track KB1 configures to the first separation/earthed switch TE1, and the second serpentine track KB2 configures to the second separation/earthed switch TE2.
In the first serpentine track KB1, be engaged with the first probe AS1, this first probe remains on bar 26.Bar 26 can translationally be passed in guiding piece 27.Guiding piece 27 is fixing on the stent 21.In the corresponding way, the second probe AS2 is engaged in the second serpentine track KB2, and wherein the second probe AS2 remains on corresponding bar 28, and this bar is from can translationally be passed in guiding piece 29.
For purposes of illustration, each in two bars 26,28 is provided with positioning indicator SA1, SA2.First positioning indicator SA1 shows: the first separation/earthed switch TE1 occupy in three possible on off state P11, P12, P13 which; And the second positioning indicator SA2 shows: the second separation/earthed switch TE2 occupy in three possible on off state P21, P22, P23 which.It is noted that aforesaid state indicating device SA1, SA2 only exist for the object illustrated, and must not force existence.
According to Fig. 2, bar 26 is parts of mechanical couplings 16, driving mechanism for switch 15 by this bar be separated with first/earthed switch TE1 connects.Correspondingly, bar 28 is parts of mechanical couplings 17, driving mechanism for switch 15 by this bar be separated with second/earthed switch TE2 connects.The translation of corresponding bar 26,28 is moved and is therefore caused the movement of the on off state of affiliated separation/earthed switch TE1, TE2 and cause it to change if desired.
The initial condition of cam disc 24 shown in Figure 2, roughly lays respectively at the beginning of affiliated serpentine track KB1, KB2 at this initial condition two probes SA1, SA2.As by two positioning indicators SA1, SA2 learn, two separation/earthed switches TE1, TE2 are on off state P11, P21 in this initial condition, and the link 11,12 of separation/earthed switch TE1, TE2 is interconnected respectively in a state in which.
Assuming that: power switch LS is in its closure state.According to Fig. 1, therefore electric current is from the first I/O EA1 to the second I/O EA2 or be possible on the contrary.
If open now power switch LS, so two separation/earthed switches TE1, TE2 such as can be switched as follows by common driving mechanism for switch 15 '.
Rotating along counterclockwise first of cam disc 24 causes: two separation/earthed switches TE1, TE2 are transitioned into its on off state P12, P22.This represents: the link 11,12,13 of two separation/earthed switches TE1, TE2 is not interconnected and therefore two separation/earthed switches TE1, TE2 open, but does not have ground connection.
Causing along another counterclockwise rotation of cam disc 24: the first separation/earthed switch TE1 remains on its on off state P12, and the second separation/earthed switch TE2 is transitioned into its on off state P23.Second I/O EA2 is therefore by the second separation/earthed switch TE2 ground connection.
Causing along counterclockwise further rotation of cam disc 24: the second separation/earthed switch TE2 remains on its on off state P23, and the first separation/earthed switch TE1 is transitioned into its on off state P13.First I/O EA1 is therefore by the first separation/earthed switch TE1 ground connection.
Therefore two I/O EA1, EA2 ground connection.
Not only the rotation in opposite direction of cam disc 24, to cause along clockwise rotation: two separation/earthed switches TE1, TE2 but also turn back to its initial condition, namely on off state P11, P21.
Self-evident, by means of the respective extension scheme of two serpentine track KB1, KB2, more or less change of the on off state of two separation/earthed switches TE1, TE2 and/or other changes of on off state also can be caused.Self-evident equally, driving control by motor 22 corresponding can affect on off state pace of change in addition.
