Compared with prior art, beneficial effect is the utility model:
1) temperature probe that the present embodiment provides, except having the basic function of thermometric, also has intensification function, can adopt DC constant voltage source to power, and can provide enough heating powers for thermal convection test of composite insulator etc.
2) temperature probe that the present embodiment provides can guarantee that volume reaches minimum.Use little probe first can reduce comparatively really the inner composite insulator that has heating defect on actual track, avoid causing because probe is excessive jacket thickness to cross thin or plug effective diameter minimizing, thereby affect the accuracy of test findings, little probe can also reduce the probability damaging when sheath injection forms simultaneously.
Accompanying drawing explanation
The structural representation of the temperature probe heating up that Fig. 1 provides for the utility model embodiment.
The manufacture method process flow diagram of the temperature probe that Fig. 2 provides for the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, the temperature probe 1 that can heat up in the present embodiment mainly comprises thermopair 11, insulating tape 12, manganese-copper filament 13 and wire 14.
Wherein, insulating tape 12 is by the anti-surface that is affixed on thermopair 11 of epoxy glue; The tight individual layer of manganese-copper filament 13 and interval are wound on insulating tape 12; Wire 14 has three wires, is respectively two heating wire electric power conductors and a thermopair transfer wire, and two heating wire electric power conductors connect respectively the difference end of manganese-copper filament 13, and thermopair transfer wire connects thermopair 11.
Refer to shown in Fig. 2, the manufacture method of the temperature probe 1 that can heat up in the present embodiment is specially:
201, the thermopair 11 of selecting suitable types, its temperature-measuring range should be greater than 300 ℃, and size should be as far as possible little, recommends: 30*5*2.5mm.
202, on thermopair 11 surfaces, apply epoxy glue, and by the anti-surface that is bonded at thermopair 11 of insulating tape 12, make its toughness one side outwardly.
203, select manganese-copper filament 13, closely on the insulating tape 12 of winding of single layer on thermopair 11.
On the one hand, because heating power is directly proportional to the coiling length of manganese-copper filament, in order to provide enough heating powers under less electric current, so the coiling length of manganese-copper filament answers long enough, the winding that manganese-copper filament should be close as far as possible, and be wound around degree of tilt should be less.And on the other hand, in order to ensure between mutually insulated, manganese-copper filament should not touch mutually, manganese-copper filament must winding of single layer, this has just limited the maximum possible coiling length of manganese-copper filament.Meanwhile, in order to make the temperature measurement result of probe as far as possible close to the actual temperature of manganese-copper filament, should be large as far as possible by the thermopair area that manganese-copper filament was wound around.Therefore the following method of recommend adoption is wound around in this enforcement, the probe that uses this canoe to obtain, its manganese-copper filament temperature and measured temperature are in 250 ℃, error is less than ± and 0.5 ℃: selecting diameter is the about 120 Ω/m of enamel-cover manganese-copper filament 13(of 0.07mm), closely on the insulating tape 12 of winding of single layer on thermopair 11, during winding, manganese-copper filament 13 can not be overlapped, and the spacing d between two row's manganese-copper filaments 13 should not surpass 0.5mm; In addition, on thermopair 11, the coiling length of manganese-copper filament 13 should be greater than the 80%(L1/L2>0.8 of thermopair 11 total lengths), the degree of tilt α of winding should be less than 30 °.
204, use electric soldering iron by upper and lower side joint and the wire bonds of manganese-copper filament 13.
The principle of work of the above-mentioned temperature probe heating up 1: use direct supply to apply voltage to manganese-copper filament 13 two ends, under the effect of ohm effect, manganese-copper filament 13 will generate heat, due to manganese-copper filament 13 be wrapped in thermopair 11 surface and with its close contact, therefore, can use thermopair 11 to read the actual temperature of manganese-copper filament 13, and due to the heating of manganese-copper filament 13, the bulk temperature of temperature probe 1 also will raise, thereby the inherent vice of testing for thermal convection provides thermal source.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
