The contact net transmission pressure mainly contains aldary, two kinds of materials of aluminium alloy.Because two kinds of different metals directly contact electrochemical reaction (forming primary element, corrosion) can occur, for the wire of copper, two kinds of unlike materials of aluminium, the contact site of corresponding temperature measuring equipment also should be copper or aluminium material when therefore the contact type temperature measuring device was installed.In addition, the sectional area of contact line conducting wire mainly contains 70mm
2, 95mm
2, 120mm
2And 150mm
2Several specifications, wherein 70mm
2, 95mm
2Two kinds of specifications be generally copper conductor, 120mm
2, 150mm
2Two kinds of specifications be generally aluminum conductor, for measure temperature accurately and reaction velocity fast, require the contact site of measurement mechanism as far as possible identical with the surface of contact net transmission pressure.But existing contact type temperature measuring device is general only for the wire of a kind of material, a kind of specification, can't satisfy the temperature survey demand of unlike material, different size contact net transmission pressure.
The utility model content
For above-mentioned deficiency, the utility model provides a kind of transmission pressure contact type temperature measuring device, can the flexible adaptation unlike material, the temperature survey demand of different size contact net transmission pressure.
The technical scheme in the invention for solving the technical problem is: transmission pressure temperature contact measurement device, comprise contact type temperature sensor body and clip, described clip is connected with the contact type temperature sensor body by screw, it is characterized in that, also comprise detachable copper sheet, the base of described contact type temperature sensor body is made by aluminium, is provided with arc groove on the described aluminium base, and is provided with fixing threaded hole in the both sides of arc groove; Described clip is that circular arc clip and two ends are provided with fixedly circular hole, and described screw passes fixedly that circular hole is connected with the fixing threaded hole of sensor body aluminium base; Curved structure and both sides are provided with leg in the middle of the described detachable copper sheet, and the arc groove both sides of described aluminium base are provided with draw-in groove, and described draw-in groove is in order to the leg on fixing detachable copper sheet both sides.
Further, the arc radius of described detachable copper sheet is less than the arc radius of aluminium base arc groove.
During installation, measured wire is put into the arc groove of base, with clip wire is blocked, and with screw clip is fixed on the base, and select whether in arc groove, to install copper sheet according to specification, the material of measured wire.
The beneficial effects of the utility model are: after adopting said structure, the utility model is for aluminum conductor in the contact line conducting wire is thick, copper conductor is thinner characteristics, by increasing a copper sheet that can split flexibly so that same sensor body base can be installed on the thicker aluminum conductor, also can be installed on the thinner copper conductor, not only can flexible adaptation contact net unlike material, the installation requirement of different size wire, improve the adaptive faculty of temperature measuring equipment, and reduced production cost and relevant expense.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
The structural representation of Fig. 1 the utility model one embodiment;
Fig. 2 is the structural representation of another embodiment of the utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of transmission pressure temperature contact measurement device of the present utility model comprises contact type temperature sensor body, clip and detachable copper sheet.The base of described contact type temperature sensor body is made by aluminium, is provided with arc groove on the described aluminium base, and is provided with fixing threaded hole in the both sides of arc groove; Described clip is that circular arc clip and two ends are provided with fixedly circular hole, and described screw passes fixedly that circular hole is connected with the fixing threaded hole of sensor body aluminium base; Curved structure and both sides are provided with leg in the middle of the described detachable copper sheet, and the arc groove both sides of described aluminium base are provided with draw-in groove, and described draw-in groove is in order to the leg on fixing detachable copper sheet both sides.Wherein, the arc radius of described detachable copper sheet is less than the arc radius of aluminium base arc groove.
The structural representation of Fig. 1 the utility model one embodiment.As shown in Figure 1, during the thinner electric transmission copper wire of a kind of transmission pressure temperature contact measurement measurement device of the present utility model, the leg on copper sheet both sides is inserted in the draw-in groove of aluminium base arc groove both sides, this measurement mechanism is fixed on the thinner electric transmission copper wire by clip, this measurement mechanism base is contacted with the electric transmission copper wire with copper product, guarantee contact line conducting wire not to be formed corrosion; Owing to inserted copper sheet, the arc groove degree of depth shoals, and the goodness of fit of this measurement mechanism base and thin electric transmission copper wire is improved.
The structural representation of another embodiment of Fig. 2 the utility model.As shown in Figure 2, during the thicker transmission of electricity aluminum conductor of a kind of transmission pressure temperature contact measurement measurement device of the present utility model, the copper sheet that at first will be arranged in the arc groove takes off, the transmission of electricity aluminum conductor is put in the arc groove on the aluminium base, this measurement mechanism is fixed on the thicker transmission of electricity aluminum conductor by clip, thereby the aluminium base is fully contacted, in order to improve accuracy of measurement with transmission pressure.
