Below, describe the present invention in detail in conjunction with the preferred embodiments and with reference to accompanying drawing, wherein:
Fig. 1 is the partial perspective schematic diagram of first embodiment of the invention;
Fig. 2 is the local schematic side view that term illustrates Fig. 1 device of the present invention;
Fig. 3 is the local schematic side view that is in the second embodiment of the invention under the non-off-state of releasing device;
Fig. 4 is the view corresponding to Fig. 3 that is under the off-state of releasing device.
Concrete form of implementation
Perspective view cuts open in the office that figure 1 illustrates first embodiment of the invention.Fig. 1 shows the shell that is assembled by two and half shells.This shell surrounds out a space that holds the electricity piece of mains switch.This shell has and is used for wanting the different supporting points of support unit and will be described later on.In the following description, be bearing on the shell and typically refer to, corresponding bearing neck, dead eye etc. are formed on the shell.This shell is made and preferably is made of plastics by insulating material.In addition, Fig. 1 shows contact supporting plate 22 in the enclosure, and it has a fixed contact that is mounted thereon 20 of mains switch 1.For the purpose of coming into plain view, the armature contact that belongs to fixed contact 20 is not shown here.Formed one one-tenth rotating circular pole orbit that touches the armature contact of bridge form in shell wall, this can see in Fig. 1.In addition, formed dead eye on shell, bridge is touched in their rotatably support activities circularly.
Switch 1 also has a release axle 2 as relieving mechanism, and it effectively is connected with armature contact, so that armature contact and fixed contact 20 are separated.This mains switch has a disconnecting apparatus (not shown), it with touch bridge and effectively be connected.This disconnecting apparatus can be an earth terminal, ratchet mechanism or similar means.This disconnecting apparatus effectively is connected with release axle 2.If operation (rotation) discharges axle 2 on the direction disconnecting, then disconnecting apparatus make touch bridge on shell the supporting point rotation and fixed contact 20 and armature contact (not shown) are separated.Like this, disconnected circuit by mains switch.
In addition, disconnecting apparatus has a kind of like this mechanism, promptly after mains switch discharges side by side except disconnect cause, makes the closing of contact by this mechanism again.Be equipped with electric arc arc control device 4 (hereinafter referred to as arc control device) for fixed contact 20.The ground, shell base that is roughly parallel to level from arc control device 4, one arc extinguishing passages 6 in Fig. 1 extends to the shell lateral surface.Arc extinguishing passage 6 and this arc extinguishing channel formation are lived on the shell side of mains switch fore side by shell wall partial closure.This arc extinguishing passage is preferably on shell one end face port, thereby can settle a plurality of shells side by side, and does not block the arc extinguishing passage mutually.The function of arc extinguishing passage and arc chamber will be described subsequently.
First lever arm 8 of one lever 10 is charged into arc extinguishing passage 6, forms an obstruction face 14 on the end face in it is arranged at arc extinguishing passage 6, and it blocks cross-section mouthful and/or cross section of arc extinguishing passage at least in part.Lever 10 turns or is bearing in swingably in the fulcrum 80 of shell.Second lever arm 18 and first lever arm 8 of lever 10 are integral, and it has a driving lever 12 on its that end opposite with fulcrum 80.Driving lever 12 is arranged on retaining 16 opposite and it and is designed in order to carry out dispose procedure discharge spool with being formed at that the retaining that discharges on the axle 2 16 contact and stirring when the released movement.By becoming the design of driving lever 12 forms, wherein this driving lever acts on retaining 16 on the disconnection direction that discharges axle 2, discharges axle 2 and can irrespectively disconnect on direction at it with driving lever 12 and moving.Therefore, can operate release axle 2 by another relieving mechanism, and not be subjected to the influence of lever 10 (driving lever 12).
Can also in Fig. 1, see, 18 one-tenth dual-shaped of the lever arm of lever 10, promptly lever arm 18 has the shape that roughly becomes U-shaped (just be " U " shape) in Fig. 1.When " U " shape bottom constitutes shaft-like driving lever 12, will " U " shape leg end rotate and be supported on the fulcrum 80 that aligns with it.In Fig. 1, the leg of U-shaped lever arm 18 is also curved C shape, thereby in Fig. 1, driving lever 12 is compared to the right with lever arm 18 fulcrums 80 with the application point of retaining 16 and offsetted.In Fig. 1, show the resting position of lever 10, the curved resting position of having aimed at lever 10 of the C shape of its Caused by Lever Arm 18, thus obstruction face 14 has obviously dwindled and/or has almost blocked arc extinguishing passage 6.The flow direction that the obstruction face of being noted that 14 is approximately perpendicular in the arc extinguishing passage is provided with.Obstruction face 14 also can outside the arc extinguishing passage, be arranged at its lead to extraneous opening near.As long as obstruction face 14 can bear the compression shock in the arc extinguishing passage 6, this is just much of that.
In the case, suitably adjust lever 10 resting positions of Fig. 1 by the weight balancing situation on lever shape and the lever 10.But, also can guarantee this resting position by springing part (not shown).This springing part can be into the tongue of helical spring, on shell or lever of extension spring or stage clip form, in addition when lever and/or shell be die casting when forming, this springing part is a tongue piece that simply is cast into.In addition, also can so design lever 10, i.e. its retaining 16 of on resting position and open position, all reclining and discharging axle with low-force.
Below, describe the function of mains switch 1 in detail in conjunction with Fig. 2.Fig. 2 is the partial side view of the mains switch of Fig. 1.As shown in Figure 1, Fig. 2 has for clarity sake also omitted armature contact or has touched bridge.
Under release conditions, by electronic repulsion make the armature contact (not shown) leave fixed contact 20 ground in Fig. 2 to moving down.When fixed contact 20 and armature contact (not shown) when touching bridge joint and touch, realized electronic repulsion by the magnetic field (following horizontal part) around the contact 22 and the bridge (not shown) that touches that is parallel to contact 22 placements.If there is high-current flow to cross mains switch, then flow through to current opposite in direction two parallel conductors (contact shoe and touch bridge).The magnetic field in the same way that the phase mutual repulsion around conductor, occurs.If electric current is big, then magnetic field is so strong, and promptly they overcome closing of contact power ground with the contact pressure separately.Obtain this closing force by spring mechanism.When separating in the armature contact (not shown) in fixed contact between 20 open electric arc cause the air pressure (about 0.5msec) in arc control device 4 to raise very apace.Pressure raises and produces the pressure wave of propagating once arc extinguishing passage 6.Arc extinguishing passage 6 is connected with extraneous, so that will become the pressure of pressure wave form to be discharged into the external world.
Through arc extinguishing passage 6 time, the obstruction face 14 that very fast pressure wave impinges is dwindled arc extinguishing passage 6 cross sections.Obstruction face because of occur surge promptly in face of stopping up the pressure reduction between the back bend towards the lateral surface (in Fig. 2 to the right) of arc extinguishing passage 6.By the bending of obstruction face 14, the lever 10 that its first lever arm 8 is provided with obstruction face 14 turns right in Fig. 2.
It should be noted that as long as obstruction face 14 bears pressure wave, promptly do not need sealing between obstruction face 14 and arc extinguishing passage 6, this is just much of that.Mainly hold up the skew of carrying out obstruction face 14 by the speed that pressure wave kinetic energy is converted at obstruction face 14 places.In other words, lever is dynamically to realize because of obstruction face is offset.Obstruction face 14 is arranged on the effect that can further strengthen obstruction face 14 in the arc extinguishing passage 6, because pressure wave is passed on the obstruction face better.
In Fig. 2, lever 10 is rotated counterclockwise around the fulcrum 80 on the shell.Second lever arm 18 on fulcrum 80 opposite sides turns left in Fig. 2.Being arranged on driving lever 12 on second lever arm, 18 ends abuts against the axle journal shape retaining 16 that discharges axle 2 and make its rotation thus on release direction.So, mains switch is released, and promptly armature contact (not shown) and fixed contact 20 are rotated and further separated by disconnecting apparatus such as earth terminal, ratchet mechanism or other similar means and by touching bridge.In other words, extinguished between the contact electric arc and in arc control device 4 arc extinguishing.
As clearly shown in Figure 2, can so select the length ratio of first lever arm 8 and second lever arm 18, the deflection of promptly bearing first lever arm 8 of low-force causes the deflection of second lever arm 18 that bears big active force.Exactly, first lever arm 8 is obviously long than second lever arm 18.Therefore, a power is applied to by driving lever 12 and discharges on the axle 2, and it is enough to discharge reliably mains switch.The bar displacement and the lever force of first lever arm and second lever arm are inversely proportional to.Pressure wave through arc extinguishing passage 6, also can successfully on second lever arm 18 produce bigger power thereby obstruction face 14 is bearing pressure reduction all the time in the long bar displacement of first lever arm 8 that is occurred with almost equal pressure.
Be to be noted that a lever 10 with an obstruction face 14 can be attached troops to a unit in each arc extinguishing passage of mains switch.Especially under the situation of multipole mains switch, it is worked under the situation in the passage of arc extinguishing separately of each lever at each utmost point that an obstruction face is respectively arranged.Perhaps, an independent lever can be connected with a plurality of obstruction faces, and these obstruction faces belong to an arc extinguishing passage respectively.For example, by the suitable sealing in arc extinguishing passage side, can realize respectively stopping up interconnecting of face.A simple solution also can be the lever that is provided with a plurality of obstruction faces at each extraneous opening part of arc extinguishing passage, promptly at each arc extinguishing channel end one obstruction face is arranged exactly simply.So, can simplify lever construction, the connection of obstruction face and arc extinguishing channel design.Obstruction face also can be designed to seal the form of the cover plate of arc extinguishing passage, and they can prevent that exotic from invading.
Now, referring to Fig. 3,4 another embodiment of the present invention is described.Its effect is represented with same tag with the same parts among Fig. 1,2, so need not these parts of repetition.
This embodiment especially is with different the pointing out of previous embodiment, stops up the arrangement of face and pressure is passed to lever construction as the release axle of relieving mechanism, and therefore here emphasis is described difference with first embodiment.
Fig. 3 is the partial side view that is in the mains switch of non-off-state, and Fig. 4 is illustrated in the identical view under the mains switch off-state.
Figure 3 illustrates arc control device that belong to the pair of contact (not shown).These arc control device are in communication with the outside by an arc extinguishing passage 6.An obstruction face 14 that is connected with a rotation axis 80 is set in arc extinguishing passage 6.Be arranged at the lever projection 18 of axle on 80 and formed second lever arm 18 of lever 10, and first lever arm of lever 10 is formed by obstruction face 14.
Be connected with first lever arm 108 of a drawbar 100 by a hinge 110, the second lever arms 18.Drawbar 100 can be fixed on the shell in a fulcrum 800 rotationally.So form hinge 110, promptly lever 10 causes drawbar 100 being rotated counterclockwise around fulcrum 800 around turning clockwise of axle 80.Corresponding situation is applicable to be put upside down when turning to.
Drawbar 100 forms a driving lever 12 on its second lever arm 118, it can with discharge axle 2 one under retaining 16 cooperating so that discharge mains switch.Similarly carry out driving lever 12 with first embodiment and cooperate, thereby abandoned repeat specification at this with retaining 16.
When producing a pressure wave (seeing the form of implementation of Fig. 2) by the electric arc between the contact in arc extinguishing passage 6, obstruction face 14 is pressed to the right in Fig. 3.In this case, obstruction face 14 also makes axle 80 and second lever arm 18 that is contained in the lever 10 on the axle turn right (clockwise).Be connected with the first drawbar arm 108 by hinge 110 by second lever arm 18, drawbar 100 is rotated counterclockwise around fulcrum 800.Second lever arm 118 turns left, and driving lever 12 makes by retaining 16 and discharges axle 2 and rotate on release direction and discharge disconnecting apparatus.Fig. 4 shows the final position of the drawbar under release condition.
So design of hinges 110 and/or driving lever 12 are connected with retaining 16, and promptly when by pressure wave release mains switch, two levers 10,100 remain on the off-position.Thus one, can see release conditions by the suitable mark on shell (color mark, range estimation window etc.) simply.In addition, hinge not only is contained in two terminal formations of the drawbar between the pin by one, but also constitutes by a film hinge, and it for example is to form when the die casting of lever 10 and drawbar 100.
, also can select the lever situation so here, promptly on the driving lever 12 of drawbar 100, produce enough release forces.
Fig. 3 or embodiment shown in Figure 4 are particularly useful for multipole mains switch, and it has a plurality of arc extinguishing passages corresponding to number of poles ground.A plurality of obstruction faces can by rotation axis 80 within each arc extinguishing passage or on so interconnect, promptly guide rotation axis through the hole in the sidewall of arc extinguishing passage separately.So, obtained the simple support of rotation axis and the excellent sealing of each arc extinguishing passage, thus the pressure wave that can in every arc extinguishing passage, remain valid.
By all obstruction faces are only connected with a drawbar that can cause that all utmost points of mains switch disconnect, can obtain a simple structure, when only when short circuit occurring on extremely for one, can discharge mains switch soon by this simple structure.
It is to be noted that in this embodiment, obstruction face also can be arranged on the end of arc extinguishing passage and/or its outside, as originally referring to Fig. 1 described.
