Description
Technical field
The invention belongs to the thermometric instruments technical field, be specifically related to a kind of temperature-induction nut testing instrument that is used to detect the temperature variations of power conductor contact.
Background technology
The temperature of many equipment equipment in operational process itself all will change, and these situations of change have often reflected the ruuning situation of equipment.The bearing of equipment for example, motor, if the temperature that the joint of transmission line of electricity etc. are located than the unexpected rising of normal operating temperature, then often devices illustrated breaks down at this moment or has potential faults, has influence on the security of operation and the serviceable life of equipment.If can monitor the temperature at above-mentioned position in real time; Make the indication of reporting to the police when rising is overheated suddenly in temperature; Just can let the plant maintenance personnel in time find, and make corresponding processing, just can avoid the generation of some serious equipment breakdowns to prevent the equipment failure expanded range.
To above-mentioned situation; Applicant has applied for that in 2008 application number is 200820026016.x, 200820026021.0,200810140166.8; 200820026879.7 Deng 4 patents about the temperature indicator (TI) that transfinites; Be used for the online detection of power transmission and transforming equipment running temperature, above-mentioned patented product has been filled up domestic blank, and its commodity are called " temperature-induction nut ".But in the prior art, also there is not the instrument that specially temperature-induction nut is carried out performance test.
Summary of the invention
The purpose of this invention is to provide a kind of instrument that is exclusively used in the temperature-induction nut performance test.
The following technical scheme of the concrete employing of the present invention:
A kind of temperature-induction nut testing instrument comprises the tester body, it is characterized in that,
Have temperature controller on the said tester body, tester top one side is provided with blower fan, and opposite side is provided with pick-up unit;
Said pick-up unit comprises two clamping plates; Two clamping plates adopts set bolt to fix; Clamping has heating plate between the clamping plate, and said heating plate is the heater element of sheet, and temperature-induction nut to be detected is tightened on one of them set bolt; Temperature-induction nut point for measuring temperature sensor is fixed in the temperature-induction nut test point, and the upper surface of clamping plate is provided with point for measuring temperature therein.
Also be provided with the wind speed adjusting knob on the said tester, be used to regulate the wind speed size of blower fan.
Tester of the present invention mainly is to be used for simulating the approximate environment that temperature-induction nut moves on power transmission and transforming equipment.Its main design philosophy is: the circuit clamping plate are heated the local pyrexia phenomenon that forms at this position because of loose contact when simulating circuit clamping plate in the practical application through electric current with heater element; And come analog line clamping plate residing external environment condition when working with fan.
Tester of the present invention is provided with the two-way point for measuring temperature: temperature-induction nut point for measuring temperature and circuit folder point for measuring temperature.Circuit folder point for measuring temperature is used for detecting the temperature rise situation of change of measurand; The temperature-induction nut point for measuring temperature is used for simulating the actual temperature that is reached of temperature-induction nut itself.The difference of the temperature of these two points for measuring temperature is the thermograde characteristic between measurand and the temperature-induction nut.
Control core parts of the present invention are temperature controllers, and the function that it is accomplished is:
1. temperature controller itself has keyboard and display, and it is preset to control temperature.
2. detect the temperature at temperature-induction nut point for measuring temperature and circuit folder point for measuring temperature place in real time; Temperature according to circuit folder point for measuring temperature compares with control temperature preset value; Control the break-make of solid-state relay with comparative result, change the heat that heating plate sends, thus the temperature of operation circuit folder point for measuring temperature.
3. can detect the temperature-induction nut switching node in when action, thus the temperature value of temperature-induction nut point for measuring temperature during the action of locking temperature-induction nut.When temperature locked, temperature controller was then controlled heating plate and is stopped heating.
4. when needs are simulated temperature-induction nut at outdoor work environment, can send control command through temperature controller, the control blower fan is simulated the environment of moderate breeze; Also can be through manually controlling the start-stop of blower fan.
The present invention is simple in structure, and it is easy to use to be used for the inspection of temperature control nut.

Embodiment
As shown in Figure 1, the temperature-induction nut testing sensor is used for detecting the temperature of temperature-induction nut point for measuring temperature; Circuit folder testing sensor is used for detecting the temperature at thalposis circuit folder point for measuring temperature place.The output electric signal of these two sensors becomes certain funtcional relationship with the temperature of the point of being tested.Sensor is sent these two electric signal into the input end that the A/D in the temperature controller changes, and simulating signal is become digital signal.Contain CPU in the temperature controller; This digital signal analyzed and handle export the break-make that a control signal is controlled solid-state relay then; Thereby realize the control of the break-make electricity of heating plate, make the control temperature at circuit clamping plate point for measuring temperature 10 places among Fig. 2 reach the temperature of setting.Among Fig. 1, a CS is arranged.When temperature controller when this switch is set is automatic, in test process, temperature controller is controlled the start-stop of blower fan automatically; If temperature controller is when this switch is set is manual, in test process, need think the start-stop of control blower fan, to reach the requirement of simulation external environment condition moderate breeze.
The input of one temperature-induction nut action connection point switch is arranged among Fig. 1, when this switching signal is effective, represent that tested temperature-induction nut moves, the temperature of temperature-induction nut point for measuring temperature when temperature controller will automatically lock switch motion, this temperature are exactly the operating temperature of temperature-induction nut.
As shown in Figure 2, a kind of temperature-induction nut testing instrument comprises tester body 2, has temperature controller 3 on the said tester body 2, and tester body 2 tops one side is provided with blower fan 1, and said blower fan 1 blowing is used for the simulating chamber external environment, and opposite side is provided with pick-up unit.
Like Fig. 3, shown in 4; When tester of the present invention uses; Earlier tested temperature-induction nut 7 is tightened in set bolt 6, temperature-induction nut point for measuring temperature sensor is fixed in temperature-induction nut test point 8, the control temperature at circuit clamping plate point for measuring temperature 10 places is set through keyboard on the temperature controller 3 and display.Heating plate 11 is sheet heater elements, and its power supply lead wire is drawn from instrument internal.The heat that heating plate 11 is sent receives the control that data are set of temperature controller 3.When the outdoor work environment of needs simulations temperature-induction nut, can through the setting of temperature controller or manually wind speed adjusting knob 4 control the rotating speed of blower fan 1, to reach the requirement of environmental simulation.
