Abstract
The utility model discloses a disc series resistance furnace with variable powers. The combination of not less than two groups of grouped resistance wires on a furnace core is changed by a regulator via conductor wires, so that the work resistance value of the utility model is changed to change the working power of the resistance furnace. A plurality of fixed working powers can be obtained to adapt to different situations, which has large temp. changing range and saves energy. In addition, fitting the feature of the variable powers, a plurality of kinds of reasonable and beautiful groove winding path shapes of the furnace core can be obtained, which breaks the single mode of the traditional groove winding path, so that the disc resistance furnace develops from simplification toward seriation.
Description
The utility model relates to the electric furnace technical field.
Existing weighing apparatus Winchester disk formula resistance furnace is to be switched on or switched off power supply by a bimetal leaf temperature distortion, makes the resistance furnace temperature weighing apparatus fixed constant.Have only a fixing operating power during use, can not satisfy and temperature requiredly use when lower or higher, and groove detours and has only the shape of a dullness.
The purpose of this utility model is just at above-mentioned deficiency, and providing a kind of can change on several fixing operating powers, and extent of alternating temperature is big and can be from the combustion chamber groove series resistance stove of unification situation of breaking traditions that detours.
In order to achieve the above object, cooperate to become these characteristics of power, detour in shape, increased several shapes that detour attractive in appearance rationally at the combustion chamber groove of resistance furnace.Go up several tie points of casting at these a series of combustion chamber grooves (the combustion chamber groove that comprises prior art), each tie point by lead with adjuster or the positive and negative connection of power supply, the present position of tie point and the mode of connection are divided into the resistance wire on the combustion chamber grouping resistor group that is no less than two groups, change the work in combination resistance value of the resistance wire that respectively divides into groups again by adjuster, thereby change the operating power of resistance furnace.
Below in conjunction with a description of drawings embodiment of the present utility model.
Figure (1) is a kind of concrete structure schematic diagram of the present utility model.
Figure (2) is the profile of figure (1) adjuster swing bolster along the A-A line.
Figure (3) is the oblique view of figure (1) adjuster swing bolster.
With reference to figure (1), in the combustion chamber groove of the existing shape that detours, respectively from two ends of groove, progressively mobile inwards certain position place casts two groups of tie points (3) that are no less than two pairs and plane symmetry simultaneously.During alternative point of contact (3) position, should be taken into account that can not allow the resistance furnace maximum service rating cross resistance wire takes advantage of loading capability.Tie point (3) can be through hole, also can be metallic object, mainly is convenient to resistance wire (2) and is connected with lead (4).Regulator base (9) is formed by the insulating material casting, be fixed with two winding contact (6) and the two piece metal arc plates (5) identical above with tie point (3) quantity, they all distinguish the center symmetry, and on two circumference in the same center of circle, the swing bolster of the fluid origin lower hollow of insulating material (7) is being supported at base (9) by rotation axis (11) and is upward freely rotating around the concentric circles center of circle, hollow space is inserted with two sheet metals that can vertically move (8), and two metal sheets (8) can contact or separation (being separation among the figure) in moving.Crossbeam (7) bottom has four grooves (10) according to the position of contact head (6) and arc plate (5) place circumference, and sheet metal (8) can be contacted with contact head (6) and arc plate (5).During wiring, the lead (4) of being drawn at two tie points (3) of the last plane symmetry of combustion chamber (1) must be connected with two centrosymmetric contact heads (6) respectively, and two arc plates (5) connect positive and negative electrode respectively.Also available other adjusters change the compound mode of grouping resistance wire.
During use, as long as transfer adjuster, the operating power of resistance furnace just can change, and resistance furnace institute thermal discharge (being usually said temperature) can change thereupon.Extent of alternating temperature is big, and can save electric energy.
Figure (4), figure (5), figure (6), figure (7) are that of the present utility model other are implemented illustration.Adjuster identical with embodiment () (two metal sheets＜8＞contacted), the mode of connection changes to some extent.The combustion chamber groove of figure (5), figure (6), figure (7) shape that detours is different from the shape of prior art.The resistivity of resistance wire should be suitably littler when implementing figure (4), figure (5), figure embodiment such as (7).
Claims (5)
1, a kind of change power disc type series resistance stove, comprise combustion chamber (1), resistance wire (2), tie point (3) and adjuster, it is characterized in that, be around in the resistance wire (2) on the combustion chamber groove of the various shapes that detour, be cast in tie point (3) in the groove from the present position and the mode of connection be divided into the grouping resistance wire that is no less than two groups, change the work in combination resistance value of the resistance wire that respectively divides into groups by adjuster.
2, according to the said change power of claim 1 disc type series resistance stove, the shape that detours that it is characterized in that said combustion chamber groove is to be shaped as benchmark with what an independent groove that is cast in the combustion chamber bosom detoured, and the groove of the several same shape of in layer equally spaced casting detours from inside to outside.
3, according to the said change power of claim 1 disc type series resistance stove, the shape that detours that it is characterized in that said combustion chamber groove is to be an end points with the combustion chamber central part, is helical form from the progressively equally spaced from inside to outside coiling of this end points.
4, according to the said change power of claim 1 disc type series resistance stove, the shape that detours that it is characterized in that said combustion chamber groove is with the combustion chamber center on a shape meaning circumference (i.e. Xiang Xiang circumference) that is the center of circle, uniform distribution is no less than two point, from the groove of the outside respectively identical shape that detours that evenly distributes of each point.
5, according to the said change power of claim 1 disc type series resistance stove, the profile that it is characterized in that said combustion chamber is discoid.
