Description

Polar armature
Technical field
The present invention relates to a kind of Polar armature that is used for supporting and turn in a kind of gas the arc extinguishing unit of the circuit breaker in the protective gas especially, this Polar armature is made up of an extreme head and a utmost point bearing, and they have the fin that cools off usefulness respectively.
Background technology
As everyone knows, when flowing through, electric current can make the contact heating.Particularly in middle pressure technology, because the use of the heat meeting limiting circuit breaker that big electric current produces in arc extinguishing unit.So need for example stipulate a maximum temperature that mustn't surpass, when surpassing this maximum temperature, for example because the fusing or the oxidation of other parts, will cause having installed circuit breaker equipment damage and can't repair.For this reason, the most handy cooling element reduces the operating temperature of large current interruption device.Especially concerning vacuum circuit-breaker.This cooling element is favourable, because the contact of this circuit breaker arranges in a vacuum, so can not cool off by the gas of convection current.
From the known a kind of circuit breaker that constitutes as vacuum switch of DE 39 41 388 A1, this circuit breaker has an apparatus for vapour-cooling in order to the cooling vacuum switch.This apparatus for vapour-cooling is connected and comprises a mozzle and the cooler with the vaporizer of vaporization cooling liquid, a collecting tank, an end sealing with a contact heat conduction of this vacuum switch.The thermal evaporation that the vaporization cooling agent is produced by electric current also flows under gaseous state in this sealing mozzle, and at this place, the vaporization cooling agent is owing to the cooling effect of cooler condensation again and be in a liquid state and flow back into this contact.But the complex structure of this apparatus for vapour-cooling, thereby significantly increased the manufacturing expense of this vacuum switch.
Have job number E50001-U229-A110 and interconnected network address from the portion of Siemens AG Representation Http:// www.e.ptd.siemens.com/webapp/EVWebApp/index de.jspThe known above-mentioned the sort of Polar armature of catalogue.In this catalogue, the circuit breaker that a kind of model is 3AH3 is disclosed.This circuit breaker comprises flange-cooled Polar armature, so that the contact of cooling vacuum switch.Shown circuit breaker is worked with sulfur hexafluoride gas.But the shortcoming of above-mentioned Polar armature is its cooling effectiveness deficiency.So the utmost point of the out of phase of a circuit breaker can only be installed mutually with sizable distance, thereby especially in medium voltage switchgear equipment, cause the big switchboard of floor space.
Summary of the invention
The objective of the invention is to improve above-mentioned Polar armature, when the breaker structure of compactness, also can reach enough big cooling effect even make it.
The present invention achieves this end like this, and fin has 6～13 mm distance and have 150～200 millimeters length in the flow direction of protective gas.
The present invention is based on following understanding: seek out sufficiently high cooling effectiveness, big as far as possible heat exchange surface must be provided between Polar armature and cool stream.So under the situation of given Polar armature structural capacity, must reduce the distance of fin, thereby increase the number of fin, and increase the area that transmits heat thus.
But cooling effectiveness is except outside the Pass the size with heat exchange surface has, also with cool stream promptly here the protective gas of usefulness to flow through the speed of heat exchange surface relevant.If the distance between the fin is too little, then can cause the obstruction gradually of the flow channel that causes by fluid, so in the distance of fin too hour, flow velocity reduces, thereby cooling effectiveness descends.
Flow process except and fin between distance dependent, also relevant with the fin length in the flow direction, so in claim 1, except providing distance range, give length range.The basis of determining the minimum range of corresponding fin is to draw from the known thermodynamics derived equation of the relation of computation bound layer density δ and fin length x:
δ(x)＝x[3,93Pr -0,5(0,952+Pr) 0,25?Gr(x) -0,25]，
P in the formula rBe equivalent to the Pu Langtuo number, G rBe equivalent to free convection number.
So the theme of claim 1 is a Polar armature with compactness of big as far as possible heat exchange surface, and avoided simultaneously because disadvantageous air-flow causes the danger that the cooling duct is blocked.Compare with prior art, Polar armature of the present invention has the cooling effect of improvement.Because the cooling effect of this improvement is not the increase owing to the external dimensions of armature, and successfully utilized for example volume as a result of regulation owing to the present invention, so in existing equipment, only need to change original Polar armature with Polar armature of the present invention simply and can cut-off bigger electric current.
In addition, the present invention achieves this end like this: extreme head and/or utmost point bearing have outside gauge plate, and fin extends between the gauge plate and in the inside of extreme head and/or utmost point bearing.In this way, the fin that extends in inside is the layered laminate layout, and these fin and the gauge utmost point interconnect, thereby have mechanical stability.In this improved structure, protective gas flows between the fin or protective gas mainly carries out in the side of extreme head from the fin outflow, and the side is not blocked by monoblock gauge plate.
Secondly, the present invention achieves this end like this: extreme head and/or utmost point bearing constitute the side plate that cube also constitutes the plane thus along its envelope, and fin extends between side plate.So on the one hand by side plate with define unlimited large-area cooling duct, both sides by two opposed fin on the other hand, the gas that surrounds this cooling duct is owing to convection current this passage of flowing through.
Certainly, within the scope of the invention, also aforesaid solution can be made up arbitrarily.
The most handy metal of Polar armature is especially made with the alloy of copper, aluminium or these two kinds of metals, so that reach good thermal conductivity.
Polar armature of the present invention is used for a kind of gas and works.But preferably a kind of protective gas of this gas is as the most handy sulphur hexafluoride of protective gas.
Polar armature of the present invention or just extreme head or just utmost point bearing have two circuit links, their mutual correspondences are arranged on the gauge plate.In this way, the electric current that flows by corresponding component is divided into two branch electric currents, so reduced extreme head and/or utmost point bearing because the heating that its internal resistance causes.
In addition, extreme head and/or utmost point bearing preferably have shunt current and come that the electric current that flows by extreme head and/or utmost point bearing is divided into multiply and divide electric current.Divide the composition electric current can reduce corresponding component because the induction by current heating that its internal resistance causes.In order to constitute the shunt that forms on this tie point between fin and gauge plate, corresponding parts can have one and be parallel to the intermediate plate that the gauge plate extends, and this intermediate plate is arranged in the centre of the corresponding component between the gauge plate and interconnects at this place and fin.Like this, the tie point between intermediate plate and the fin is exactly a shunt current, and they are applicable to total current is divided into the parallel branch electric current of multiply.
In a kind of rational improvement structure of Polar armature of the present invention.It is unshakable in one's determination that this utmost point bearing has a supporting, and this iron core comprises that the mutual opposed side plate of monoblock and a piece of cloth put the connecting plate that being used between side plate supported bus-bar.Connecting plate opposite between side plate is provided with fin, and these fin can make protective gas flow into supporting inside unshakable in one's determination.Side plate the additional connection on connecting plate next door unshakable in one's determination by supporting above fin further increased heat exchange surface.In addition, the hole between the fin provides condition and has reached supporting inside cooling unshakable in one's determination thus for the inflow of protective gas simultaneously.
In a corresponding scheme, it is unshakable in one's determination that this utmost point bearing is furnished with a supporting, and the fin that this iron core is cube and has mutual opposed monoblock side plate and interconnect side plate wherein is that the moving component of arc control device unit leaves the space in supporting inside unshakable in one's determination.When this structure of the present invention, mainly cool off in the inside of utmost point bearing.
In a suitable improved structure, on the side plate of utmost point bearing, be provided with outward extending outside heat sink, so just can strengthen inner cooling.
