Background technology
In low-voltage distribution system, switching device is placed in shell.Switching device includes switchgear.Switchgear is to recall unit, and its form is the drawer in the cupboard being inserted into being placed in shell.Switchgear includes one group of main contacts and one group of auxiliary contact.Two groups of contacts are all placed in the back side of equipment.Main contacts is for contacting with the paired distribution bus of arranged perpendicular in frame.Auxiliary contact are for contacting with the relief cable side contacts of the cable being connected to auxiliary circuit.
Switchgear provides multiple connection status, and they are by main isolation switch and select by recalling switchgear partially or completely from cupboard.Under indicate various states.
| State | Unit | Main isolation | Main contacts | Auxiliary contact | Testing button lamp |
| Connect conducting | Insert | Guan Bi | Connect | Connect | Go out |
| Connect and turn off | Insert | Disconnect | Connect | Connect | Go out |
| Test | Recall 30mm | Disconnect | Disconnect | Connect | Bright |
| Disconnect | Recall 45mm | Disconnect | Disconnect | Disconnect | Go out |
| Remove | Remove from frame | - | - | - | - |
Switchgear is configured such that state only can change to one or two corresponding to moving up or down in other states of a line in table.It is configured so that for reasons of safety.Therefore, in order to connect the transition between off state and test mode, main isolation must flow through main isolation and switches off.For this, there is a kind of specific mechanism.
In order to keep connecting in " connecting conducting " and " test " state, the relief cable side contacts of auxiliary circuit extends upwardly to few 30mm in the side that drawer is withdrawn.When drawer is withdrawn into " test " state from " connecting conducting " or is further inserted into cupboard to " connecting conducting " state from " test " state, auxiliary contact slide along relief cable side contacts.But, the contact of slip is less reliable, because they are worn and are likely to contaminated.
But, there is following risk: drawer is likely to unexpectedly to close or it is likely to from recalling the position change of 45mm to the position only recalling 30mm.Such as when someone or something are encountered drawer or lean on drawer, it may occur however that this accidental switch off or position change.The accidental change of this position corresponds to the change of state and is therefore dangerous.Such as, when from recall 45mm be changed to recall 30mm, auxiliary circuit connect or disconnect.
Summary of the invention
It is an object of the invention to provide a kind of switchgear reduced at least in part or eliminate this problem.
According to the first embodiment of the present invention, it is provided that a kind of switchgear, including
-with the first contact of the first electrical contact；
-the second contact of contacting with second circuit；
-the first drive mechanism；
-the second drive mechanism, including fan-shaped mechanism and rackwork, rackwork is connected to the second contact and fan-shaped mechanism is configured to be transformed into the rotation of rotatable drive member the movement of rackwork；
-rotatable drive member has the orientation of the first scope, and wherein, the first drive mechanism drives the first contact between the first link position and the first open position, and wherein, fan-shaped mechanism does not engage with rackwork；And having the orientation of the second scope, wherein, rackwork engages with fan-shaped mechanism and drives the second contact between the second link position and the second open position.
It will be appreciated by those skilled in the art that sector and anodontia sector that fan-shaped mechanism includes having tooth, and rackwork has tooth.Those skilled in the art will also appreciate that, in the combination of fan-shaped mechanism and rackwork, relative to the orientation of rackwork, fan-shaped mechanism determines that fan-shaped mechanism engages with rackwork and rackwork is driven, or fan-shaped mechanism does not engage with rackwork and rackwork is not driven.This is because only when the sector with tooth is engaged with tooth bar, when namely wherein having the indented joint of tooth and rackwork of the sector of tooth, fan-shaped mechanism can mobile rack.Therefore, when fan-shaped mechanism rotates, by the continuous rotation of rotatable drive member, rackwork is driven intermittently.The orientation of the first scope corresponds to anodontia sector in the face of rackwork, and the orientation of the second scope corresponds to the sector with tooth in the face of rackwork, and the indented joint of the tooth of this sector and rackwork.
Because rotatable drive member also drives the first drive mechanism, so the connection status of the first contact and the second contact can also be controlled by drive member, so that the first contact can be disconnected and the second contact maintenance connection.Here, when rotating in the orientation in the first scope, rotatable drive member drives the first contact indirectly between the first link position and the first open position.In the orientation of the first scope, (that is, the tooth of the sector with tooth of sector mechanism not with the indented joint of rackwork) engage with rackwork by fan-shaped mechanism.Therefore, in the orientation of the first scope, rackwork does not move, and thus the second contact is not moved.
Because rotatable drive member drives the first drive mechanism and the second drive mechanism by rotating, it is possible to handle switchgear by introducing the rotary motion of rotatable drive member.This is preferably as motor or the rotating disk that is configured to be operated by user can be passed easily through to provide rotary motion.
According to the second embodiment of the present invention, provide the switchgear of first embodiment, wherein, rotating parts rotation in a first direction is corresponding to moving the second contact to the second link position from the second open position, and is moved to the first link position from the first open position the first contact.
In this embodiment, when drive member rotates enough angles, the second and first contact is sequentially connected.It is apparent that will sequentially disconnect the first contact and the second contact by rotating in a direction opposite the first direction.
According to the third embodiment of the invention, first drive mechanism includes fan-shaped mechanism and is connected to another rackwork of the first contact, fan-shaped mechanism included by first drive mechanism is configured to be transformed into the rotation of rotatable drive member the movement of another rackwork, wherein, when rotatable drive member is in the orientation of described second scope, the fan-shaped mechanism of the first drive mechanism does not engage with another rackwork.
The rotary motion of rotatable drive member is converted to the linear mobile of the first contact by another rackwork included by the first drive mechanism and fan-shaped mechanism.
Because when rotatable drive member is in the orientation of the second scope, namely when the second contact is moved between the second link position and the second open position, this another rackwork does not engage (being namely not engaged with) with the fan-shaped mechanism of the first drive mechanism, so switchgear can keep relatively small.This is because otherwise when the fan-shaped mechanism of another rackwork and the first drive mechanism engages, the linear mobile of it will be continued in the first contact, thus certain space being needed to adapt to this linear movement.
In the 4th favourable embodiment of the present invention, the switchgear fan-shaped mechanism included by the 3rd embodiment and the first drive mechanism is the fan-shaped mechanism included by the second drive mechanism, and the tooth of fan-shaped mechanism is crossed over the sector less than 180 degree and rackwork and another rackwork and diametrically configured around fan-shaped mechanism.
By rackwork and another rackwork are arranged in the position diametrically that the half around less than circumference has the fan-shaped mechanism of tooth, the tooth of fan-shaped mechanism can not simultaneously engage with rackwork and another rackwork simultaneously.Therefore, the first contact and the second contact can not be moved simultaneously.
By using a fan-shaped mechanism for the first drive mechanism and the second drive mechanism, switchgear needs little space.Additionally, this is relatively inexpensive scheme.
According to the fifth embodiment of the invention, fan-shaped mechanism is configured around fan-shaped mechanism shaft and rotates, and connecting rod is hingedly attached to rackwork at the first end and is hingedly attached to drive rod at the second end, and drive rod is connected to the second contact；Connecting rod is configured around being parallel to pivotally turning of fan-shaped mechanism shaft.
The advantage of this embodiment is the motion of the rackwork motion in particular directions drive rod corresponding to having rightabout component.Therefore, the rotation in a direction of the fan-shaped mechanism is moved in the same direction corresponding to the first contact and the second contact, rather than moves in the opposite direction.
According to the sixth embodiment of the invention, fan-shaped mechanism is configured around fan-shaped mechanism shaft and rotates, connecting rod is connected to rackwork by the first pin, connecting rod is connected to the drive rod being connected with the second contact by the second pin, first pin is configured to rotate and slide through the first groove of connecting rod, second pin is configured to rotate and slide through the second groove of connecting rod, and wherein, connecting rod is configured around being parallel to pivotally turning of fan-shaped mechanism shaft.
The advantage of this embodiment is the motion of the rackwork motion in the direction drive rod corresponding to having rightabout component.Therefore, (the enough angles) rotation in a direction of fan-shaped mechanism is moved in the same direction corresponding to the first contact and the second contact, rather than moves in the opposite direction.
Additionally, because pin can rotate in corresponding groove and can slide in corresponding groove, so connecting rod only transmits the power of the moving direction being parallel to the second tooth bar.Additionally, the second contact moves up in the side parallel with the moving direction of the second tooth bar, it is not necessary to expose to the power driving it in vertical direction.
Preferably, drive rod is directed to part guiding to cause pin slip in they corresponding grooves.
According to the seventh embodiment of the invention, the tooth of the tooth of rackwork and another rackwork points to same direction, and when rotatable drive member (15) rotates in a first direction, fan-shaped mechanism and another fan-shaped mechanism are configured to rotate in the same direction.
