Abstract
Three-position switch (DS..) driving device (AE) for electricity supply and distributing switch equipment (SA) includes a thrust-rods (SB..) having one free end joined to a lifter-drive (HA) so that the thrust-rods (SB) undergo an approximately vertical lifter-drive deflection (HG) to obtain an approximately horizontal thrust-rods amplitude of oscillation (SG). The thrust-rods (SB..) are joined to the three- position switches (DS) which are arranged tandemly in the switch apparatus (SA) such that the movable parts of the three- position switches are swivelled into the controlled switching positions IN,OUT and EARTH by means of a radial deflection (RA). The driving device of the invention is especially applicable to an air-insulated middle voltage switching device.
Description
The present invention relates to that in a kind of power supply and the distribution switchgear three-position type switch is used, especially the drive unit that the three-position type switch is used in the gas-insulated medium voltage switchgear equipment, it is located at central rotatable selector axle, on the selector axle, always arrange its quantity and the corresponding crank of the number of phases that will select side by side, the position of the switch " connection ", " disconnection " and " ground connection " of the three-position type switch that is arranged in juxtaposition equally on can parallel selection distribution board by means of them.
The drive unit of the described type of preface for example from DE 3239839C1 as can be known.Wherein described drive unit discloses by making and has been used for the principle design of three-phase three-position type electric switch of maneuveringair insulated switching installation.The design that is used for the drive unit of gas-insulated switchgear is similarly, but the transmission device of introducing from the outside in this case, cable joint etc. all enter the gas tank inner chamber by means of airtight insulating sleeve.Such as already mentioned, depend on that basically the three-phase three-position type switch of the manipulation of these known drive means is arranged in juxtaposition, so the switchgear that for example has three phase places that will select, volume must design quite greatly.In addition, for gas isolated switchgear, must the relatively more expensive gas-tight container of preparation.
The objective of the invention is to, overall for switchgear, but especially determine a kind of drive unit for gas isolated switchgear, it can make switchgear that remarkable compactness and low-cost configuration are arranged, yet can not be lower than safety standard general in present technique.
The object of the present invention is achieved like this, promptly, adopt that in a kind of power supply and the distribution switchgear three-position type switch is used, especially the drive unit that the three-position type switch is used in the gas-insulated medium voltage switchgear equipment, it is located at central rotatable selector axle, the position of the switch " connection ", " disconnection " and " ground connection " of waiting to connect phase place on can parallel selection distribution board by this selector axle, wherein
1.1 this drive unit has the push rod of alternative device axle,
1.2 this push rod respectively is connected with stroke driving device by a free end, makes can make the push rod of each distribution board obtain a push rod amplitude of oscillation that is similar to level by a deflection that is similar to vertical stroke driving device,
1.3 the three-position type switch is arranged before and after in switchgear,
1.4 push rod is connected with the three-position type switch, makes to be similar to the push rod amplitude of oscillation of level by them, and the motion parts of three-position type switch is selected in the position of the switch " connection ", " disconnection " and " ground connection " pivotally by radial deflection.
By using push rod, thereby particularly adopt the deflection of push rod by means of simple stroke driving device, by power transmission along straight line, substitute the power transmission radially of known drive axle and give the moveable contact part of three position switch, thereby can will in series and no longer be to be arranged in the switchgear side by side before and after the three-position type switch.Therefore, the floor space of three-position type switch becomes along the positive degree of depth of switchgear from the frontal width along switchgear to be laid, the switchgear volume that has consequently obtained generally obviously to reduce when power ratio is identical.This vantage of comparing with known switch equipment is also owing to the radial deflection of three-position type switch moving component is further strengthened.
According to a favourable improvement design of the present invention, wherein
2.1 stroke driving device acts on the push rod of two arrangements parallel to each other simultaneously; And
2.2 be connected to the parallel motion always of the push rod of these arrangements parallel to each other with the moving component of three-position type switch.
Therefore obtain the power transmission of symmetry effect on the switch contact of motion, it can all evenly be converted to switch contact the different position of the switch with respect to the loss of switch corner tinily.
Another favourable improvement design code of the present invention has following feature:
3.1 stroke driving device by means of transmission gear for electric motor and/or can be manual transmission device realize.
Because this feature can satisfy desired lower-cost condition in this type of air or gas-insulated switchgear.
Below by means of further specifying the present invention at the embodiment shown in three accompanying drawings, shown in it as the three-phase, gas insulated medium voltage switchgear equipment of switchgear scope.
Fig. 1 is the end view of three-phase, gas insulated medium voltage switchgear equipment;
Fig. 2 is the vertical view of medium voltage switchgear equipment shown in Figure 1;
Fig. 3 is the front view of this switchgear.
For see clearer for the purpose of, only be depicted as briefly and understand parts essential to the invention.
Fig. 1 represents that the gas-insulated switchgear SA that is made of three continuously arranged phase place SF1, SF2, SF3, its three-position type switch DS.. are contained in the public air chamber.For realizing selectively power supply and distribution, cable joint KA.. is by means of three-position type switch DS.. and relevant bus SS.. connection in the known manner.Connect in order to cut off this, three-position type switch DS.. can be by means of push rod SB not further radially deflection of zone of the stationary contact member on bus SS.. of expression from figure.The motion of push rod SB.. produces on fork SH by means of the deflection HG of the stroke driving device of stroke driving device HA by being similar to vertical effect.By on off state " ground connection " (in the motion contact element of this state three-position type switch DS.. and relevant earthing contact EK connection), operating personnel can be non-dangerously near cable joint KA...Represent also among the figure that in addition cable joint KA.. and stroke driving device HA are by means of insulating sleeve DF.. or other the capping inner chamber of insertion switch equipment SA airtightly.
Fig. 2 is the vertical view of gas isolated medium voltage switchgear equipment, therefrom mainly can see two parallel push rod SB1, SB2, is furnished with three-position type switch (DS.. among Fig. 1) the quilt contact element of transmission campaign symmetrically between them.In addition, locate successively before and after can seeing, here the three-position type switch that does not indicate adopts this layout can obtain the special compact structure form of switchgear SA.
Fig. 3 is the front view of medium voltage switchgear equipment, can see especially that therefrom the bus SS.. of perforation comes extension facility by the joint that it is positioned at the air chamber outside.Can see can be from the below approaching cable joint KA.. that is arranged in the air chamber outside equally, they with figure in not expression be used to power and being connected of the cable of distribution, by means of removable screw connection by manually finishing.
