In the presence of the potential safety hazard of electric shock.
In addition, in the temperature checking method of the cable primary side cable accessory of prior art, surface acoustic wave thermometry is real
The method for now monitoring practical on-line, its principle is that surface acoustic wave is passed in one kind that solid half-space surface is present along surface
Broadcast, energy concentrates on the elastic wave of near surface, its temperature is determined by measuring surface acoustic wave.Surface acoustic wave thermometry it is detailed
Details condition refer to the work such as Yao Jianhua《In-Line Temperature Measure System design and development based on SAW Temperature Sensors》, carry《Zhejiang
River electric power》4th phase in 2014；Old snow common vetch《The research of GIS switch contact temperature monitorings based on surface acoustic wave》, March 1 in 2015
Day, the pertinent literature such as North China Electric Power University's Master's thesis.
Utility model content
The purpose of this utility model is that design one has safety can in the cable primary side cable accessory of longtime running
By the SAW Temperature Sensors of property, it is to avoid the safety risks that con-ventional handheld thermometric is present.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of temperature monitoring sensor for cable primary side cable accessory, including metal temperature-sensitive bottom plate and be embedded in described
It is provided with and connects with primary side cable accessory on surface acoustic wave temperature detecting module on metal temperature-sensitive bottom plate, the metal temperature-sensitive bottom plate
The breach connect.
A preferred embodiment of the present utility model, in addition to it is located at the sensor day of the metal temperature-sensitive backplate surface
Line, the sensor antenna is electrically connected with the surface acoustic wave temperature detecting module.
A preferred embodiment of the present utility model, the material of the metal temperature-sensitive bottom plate is corronil.
A preferred embodiment of the present utility model, the surface acoustic wave temperature detecting module uses EPCOS632 chips.
In a preferred embodiment of the present utility model, the breach includes the opening and semicircular holding part of rectangle.
Temperature monitoring sensor of the present utility model, the function with surface acoustic wave temperature monitoring, while metal temperature-sensitive bottom
Plate also has sealing connection sheet function, and metal temperature-sensitive bottom plate is attached on primary side cable accessory, and accuracy of data acquisition is high, without electricity
Source, performance safety are reliable.
Brief description of the drawings
, below will be right in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The accompanying drawing used required in embodiment or description of the prior art is briefly described.
The temperature monitoring sensor structural representation for cable primary side cable accessory that Fig. 1 provides for the present embodiment.
Fig. 2 is the temperature monitoring sensor use state schematic diagram of the present embodiment.
Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described
Embodiment is a part of embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality
Novel protected scope.
As shown in figure 1, the temperature monitoring sensor for cable primary side cable accessory that the present embodiment is provided, including gold
Belong to temperature-sensitive bottom plate 1 and the surface acoustic wave temperature detecting module 2 being embedded on the metal temperature-sensitive bottom plate 1, the metal temperature-sensitive bottom plate 1
On be provided with the breach 11 being connected with primary side cable accessory.Preferably, breach 11 includes the opening and semicircle of rectangle
Holding part, semicircular holding part is in order to which the shape with cable is engaged.
Fig. 2 is please also refer to, this temperature monitoring sensor 100 is arranged on to the tail of primary side cable accessory 200 of cable 300
End closure, according to shown in arrow, primary side cable is enclosed on by the breach 11 of the metal temperature-sensitive bottom plate 1 of temperature monitoring sensor 100
On annex 200, it is screwed on terminal.Temperature monitoring sensor of the present utility model, due to metal temperature-sensitive bottom plate 1 with
Primary side cable accessory is contacted, and the surface acoustic wave temperature detection mould on essentially identical temperature, metal temperature-sensitive bottom plate 1 is kept with it
Block 2 is using surface acoustic wave thermometry monitoring cable primary side cable accessory temperature conditions, to judge cable primary side cable accessory
Whether overheating conditions are had.On the one hand this sensor has the function of surface acoustic wave temperature monitoring, while metal temperature-sensitive bottom plate is also real
Show sealing connection sheet function, instead of the sealing of cable primary side cable accessory tail end in flakes.With taking hand-held in the prior art
The metering system of sensor is compared, by the way that metal temperature-sensitive bottom plate 1 is fixed in terminal block, instead of primary side cable accessory tail end
Seal gasket, is directly contacted with sites of heat generation, and accuracy of data acquisition is high, reliable without power supply, performance safety.Due to without artificial
Hand-held sensor is close to power supply, it is to avoid Personal Risk.
