Abstract
The utility model relates to the technical field of an electronic and electrical component, in particular to a multipoint high power wire wound resistor. The resistor comprises a ceramic hollow tube. Brackets are respectively arranged at the two ends of the ceramic hollow tube. A plurality of alloy resistance wires are wound on the periphery of the ceramic hollow tube discontinuously. Jointing clamps are respectively arranged between the adjacent alloy resistance wires. The periphery of the alloy resistance wires is encapsulated by an insulating resin layer. After the technical scheme is adopted, a plurality of alloy resistance wires can be wound on the same ceramic hollow tube of the wire wound resistor and are equivalent to a plurality of wire wound resistors. The wire wound resistors can meet the use requirement of a plurality of circuit units and the size of the wire wound resistors is equivalent to the size of one traditional wire wound resistor, therefore the size and the needed installation space of a circuit system are greatly reduced and the cost is saved. Moreover, the output resistance of the multipoint high power wire wound resistor can be adjusted by being connected with different jointing clamps, i.e. one article have multiple purposes.
Description
Technical field:
The utility model relates to electric Element Technology field, refers in particular to a kind of multipoint mode large power winding resistance.
Background technology:
At industrial circles such as electric power system and elevators, need use large power winding resistance usually, according to each several part circuit difference, need with many group wire resistors; Existing large power winding resistance is generally fixes one group of resistance, be that each wire resistor can only use for a circuit unit, so need the large power winding resistance number used many in the entire circuit system, therefore make that entire circuit system occupation space is big, cost is high.
The utility model content:
The purpose of this utility model is to provide a kind of multipoint mode large power winding resistance at the above-mentioned weak point of existing large power winding resistance.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of multipoint mode large power winding resistance, this resistance comprises a ceramic hollow tube, two ends in described ceramic hollow tube are separately installed with support, be arranged with several alloy resistance wires the peripheral discontinuous of described ceramic hollow tube, between adjacent described alloy resistance wire, be provided with binding clip, and described alloy resistance wire periphery is encapsulated by insulating resin layer.
Wear a screw rod in described ceramic hollow tube, described support is fixed on the two ends of described ceramic hollow tube respectively by nut and being connected of screw rod.
After the utility model adopts technique scheme, on the ceramic hollow tube of same wire resistor, the a plurality of alloy resistance wires of winding simultaneously, be equivalent to a plurality of wire resistors, can satisfy a plurality of circuit units uses, its volume then is equivalent to use an original wire resistor, has therefore significantly reduced the volume and the required installing space of Circuits System, saves cost.And the output resistance of the utility model multipoint mode large power winding resistance can also be regulated by connecting different binding clips, promptly realizes one-object-many-purposes.
Description of drawings:
Fig. 1 is the structural representation of the utility model multipoint mode large power winding resistance.
Embodiment:
As shown in Figure 1, wire resistor described in the utility model comprises a ceramic hollow tube 1, in described ceramic hollow tube 1, wear a screw rod 11, be separately installed with support 2 in the two ends of described ceramic hollow tube 1, described support 2 is fixed on the two ends of described ceramic hollow tube 1 respectively by nut 12 and being connected of screw rod 11, the effect of support 2 is to be convenient to whole wire resistor is installed in the circuit.
Be arranged with several alloy resistance wires 3 the peripheral discontinuous of described ceramic hollow tube 1, between adjacent described alloy resistance wire 3, be provided with binding clip 4, and described alloy resistance wire 3 peripheries are by insulating resin layer 5 encapsulation.Insulating resin layer 5 is with the arch section encapsulation of alloy resistance wire 3 and binding clip 4, and the wire connecting portion of binding clip 3 exposes so that connection line.Adopting insulating resin layer 5 encapsulation, can be that alloy resistance wire 3 is isolated from the outside, and avoids oxidized, can keep the resistance wire stable performance, also user and setter is played the effect of insulation protection simultaneously.
After the utility model adopts technique scheme, on the ceramic hollow tube of same wire resistor, the a plurality of alloy resistance wires of winding simultaneously, be equivalent to a plurality of wire resistors, can satisfy a plurality of circuit units uses, its volume then is equivalent to use an original wire resistor, has therefore significantly reduced the volume and the required installing space of Circuits System, saves cost.And the output resistance of the utility model multipoint mode large power winding resistance can also be regulated by connecting different binding clips, promptly realizes one-object-many-purposes.
The utility model is applicable to high voltage, and is high-power, and the heavy current pulse circuit has that volume is little, shatter-proof, moisture-proof, heat-resisting and excellent radiating effect, the overburden of anti-short time the, low noise, a resistance advantage such as stable all the year round.
