Abstract
The invention relates to a multipole switch (2) for interrupting multi-phase current, and especially relates to an on-load isolating switch for low pressure. The multipole switch (2) is provided with switch contact points which are both movably and fixedly disposed and are correspondingly assembled for each current. The switch contact points are mutually separated through a switch shaft (3) to disconnect the switch (2). The switch shaft is composed of cylinder-shaped switch shaft modules (11). The end sides of the switch shaft modules (11) directly lean against each other and are mutually connected by means of a connecting device to transmit torque. Each switch shaft module (11) is assembled with at least one switch contact point pair. To keep the structural space of the switch (2) small, it is suggested that the connecting device comprises middle components (13) and grooves (12) which coordinate with each other. The groove (12) is designed at the end side of the switch shaft module (11) and extends along the rotation aixs of the switch shaft. The middle components (13) are respectively inserted into the grooves (12) which are oppositely disposed.
Description
Technical field
The present invention relates to a kind of multipole switch, load disconnecting switch in particular for low pressure, this switch has movable and switch contact fixed and arranged that sets for each current phase correspondence, described switch contact is separated from each other by the rotation of switch shaft, in order to disconnect described switch, this switch shaft is by columniform switch shaft module composition, described switch shaft module is distolateral directly mutually to recline and interconnects so that transmitting torque by jockey antitorquely, wherein, set at least one switch contact pair for each switch shaft module.
Background technology
The multipole switch of load disconnecting switch form is known and be used for to interrupt multiphase current.For current phase sets movable and switch contact fixed and arranged in this correspondence, this switch contact lays respectively in the pole shoe and by switch shaft and is separated from each other so that cut-off switch.Switch shaft is comprised of a plurality of modules (shaft part), and these module sides directly recline mutually.Module interconnects antitorquely, so that can transmitting torque.For each module is furnished with at least one pair of switch contact.
Disclose a kind of switch shaft by module composition by patent documentation WO2005/069324, wherein, module interconnects by the cooperation of shape face.At this, form a gear (external gear) in each module, in the internal gear of the module complementation of this gear insertion direct neighbor.Essential is that external gear correspondingly stretches out affiliated pole shoe, that is side direction stretches out from switch for this reason.
Deflection structure space by this way, this has confirmed it is disadvantageous especially in being installed to switch cubicle the time.Because it is rotatable mobile parts, so also can block.Therefore, need side direction to hide to I haven't seen you for ages.In addition disadvantageously, the driven flank of tooth and tooth relatively easily produce tolerance, and this has reduced the quality of fit of each module.
Have intermediary element or the intermediate module that needs the gap by patent documentation WO 03/050830 and US 6,259, the 338 known switch shafts that formed by shaft part.This has the shortcoming that increases the switch width equally.
Summary of the invention
Technical problem to be solved by this invention is, advises a kind of switch shaft by module composition, and this switch shaft has been avoided above-mentioned shortcoming.
This technical problem is by a kind of multipole switch, in particular for the load disconnecting switch solution of low pressure.This multipole switch has movable and switch contact fixed and arranged that sets for the current phase correspondence, this switch contact is separated from each other by the rotation of switch shaft, so that cut-off switch, this switch shaft is by columniform switch shaft module composition, this switch shaft module is distolateral directly mutually to recline and interconnects so that transmitting torque by jockey antitorquely, wherein, set at least one switch contact pair for each switch shaft module.
This solution regulation, jockey comprises mutual synergistic intermediary element and groove, wherein, it is distolateral upper and extend along the switch shaft rotation that groove is separately positioned on two of switch shaft, and intermediary element is inserted respectively in the groove that faces with each other.Guarantee by this way, the switch shaft module side is to not stretching out electrode box.Exist respectively on distolateral and have suitable cross-sectional profiles, for example quadrangle, hexagon, star or criss-cross groove.Intermediary element is inserted respectively in the opposed facing groove, that is, their shape face formula ground filling grooves.This intermediary element is the section moulding, have the object of corresponding outline in its whole length.
Description of drawings
The below further describes the present invention according to embodiment.In the accompanying drawing:
Fig. 1 before installing not with intermediary element, have the stereogram of the isolating switch of operating means,
Fig. 2 is the stereogram of two switch shaft modules isolating switch, that have intermediary element shown in Figure 1,
Fig. 3 be intermediary element the first cross form of implementation and
Fig. 4 is the second cross form of implementation of intermediary element.
Embodiment
Fig. 1 is illustrated in the switch with operating means 12 before installing, and wherein, switch 2 is designed to three utmost point load disconnecting switchs, that is, have three electrode box 2a.Switch 2 has switch contact not shown further, and this switch contact can disconnect and closure by the switch shaft 3 that is made of switch shaft module 11 (referring to Fig. 2).(only seeing the end face that belongs to respectively switch shaft module 11 (shaft part) electrode box 2a, that have end face groove 12 (referring to Fig. 2) from switch shaft 3 in Fig. 1) isolating switch 2 can be connected with three-phase circuit by connector 4,5.
Operating device 1 is arranged in housing 6, and the free end of driving shaft 7 stretches out from the sidewall of housing 6, and driven shaft 8 stops with this sidewall with switch shaft module 11 the same ground with flushing.
When mounted, the switch shaft module 11 of driven shaft 8 and switch shaft 3 interconnects antitorquely.In order to connect driven shaft 8 and corresponding switch shaft module 11 and each switch shaft module 11 to be interconnected, distolateral groove 12 comprises that the corresponding intermediary element 13 (referring to Fig. 2) of inserting in this groove 12 is as jockey.
Driving shaft 7 further has groove 9 equally, and the end of handle can be inserted in this groove 9.Driving shaft 7 can turn to the make position I from open position 0 (as shown in fig. 1) at this, and vice versa.Mark 10 represents open position 0 in Fig. 1.
Fig. 2 illustrates two switch shaft modules 11 of switch shaft 3, and this two switch shaft modules 11 distolateral has respectively groove 12, and each groove 12 has four spring groove 12a that arrange at its circumference.Two switch shaft modules 11 directly recline under installment state mutually, and wherein, as intermediary element 13, middleware 13a when mounted shape face longitudinally inserts in two opposed grooves 12 along switch shaft ordinatedly.Because the cross section outline of their complementations (have four ear shapes expand the outline 14 of the 14a of section), intermediary element 13 respectively transfer function on switch shaft module 11 and therefore be applied to moment of torsion on the switch shaft 3.
Fig. 3 illustrates the criss-cross structural design of intermediary element 13.Criss-cross intermediary element 13 (outline 14 with tooth 15 of four rectangular parallelepiped shapes) has interference fit with adjacent switch axle module 11 at this in a side, and having matched in clearance at opposite side, this can realize the axial tolerance compensating of switch shaft module 11.
At intermediary element 13 (outline 14 with tooth 16 of four rectangular parallelepiped shapes) in same criss-cross structural design shown in Figure 4, connection between each driven flank of tooth (each tooth 16) designs to such an extent that have resilient flexibility, in order to compensate in the circumferential direction of the circle pitch error.
