The beneficial effects of the utility model are that: (1 ) simple structure, low in manufacturing cost, (2 )When the temperature of the temperature check point on distribution equipment was higher than to set the temperature, temperature detect switch will be closed automatically to with whole circuit conduction, the LED lamp will give out light, thereby instructs out the high temperature of this temperature check point, so that the maintainer in time overhauls distribution equipment.
Description
Technical field
The utility model relates to a kind of controller switching equipment excess temperature indicating device, particularly a kind of controller switching equipment excess temperature indicator.
Background technology
Along with the rising of power industry electric pressure and the increase of transfers loads capacity, require more and more higher to controller switching equipment reliability of operation, equipment and wire and wire and terminal place are the places that resistance is larger, due to reasons such as Joule heats, joint easily generates heat, metal is caused to be oxidized, cause the further increase of resistance, joint mechanical performance is easily caused to reduce if go down for a long time, even there is the phenomenon that joint is blown, therefore the heating of equipment is more and more paid attention to, according to respective rules require every half a year thermometric once.
Temperature measuring device conventional at present mainly contains infrared point temperature measurer and infrared thermography, there is following point when infrared point temperature measurer uses:
1, along with the insulation of the transformation of overhead transmission line insulating and joint bare spots is encapsulated, infrared point temperature measurer is made cannot to continue to use;
2, infrared point temperature measurer cannot be measured not near cable shaft or the temperature of the cable mid head of direct-burried (thermometric key point), also cannot measure the device temperature above the upper strata bar that blocked by infrastructure devices;
3, Infrared wavelength is generally more than 5 μm, therefore can not carry out thermometric through various bin view window, and glass has very special reflection and through characteristic, cannot obtain accurate infrared temperature reading.
Infrared thermography is imaged to whole object with the form in " face ", operator just can tentatively judge heat condition and trouble location by the image color of screen display and follow-up of hot issues Presentation Function, then subsequent analysis in addition, thus judge whether to there is focus, but there is following point:
1, infrared thermography is by temperature difference imaging, and the general objectives temperature difference is all little, and therefore infrared chart image contrast is low;
2, infrared thermography detection is less than the temperature difference after this transparent barriers thing of bin window-glass;
3, expensive, generally all more than 100,000 Renminbi.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of structure simple, thermometric can be carried out to the point for measuring temperature on electrical equipment in real time and when the temperature of point for measuring temperature is higher than the controller switching equipment excess temperature indicator sending pilot light during design temperature in time.
In order to solve the problem, controller switching equipment excess temperature indicator of the present utility model, comprise the LED of battery, temperature detect switch (TDS), divider resistance and instruction, described battery, temperature detect switch (TDS), divider resistance and LED are in series, described temperature detect switch (TDS) is provided with temperature sense sheet, and described temperature sense sheet is connected with the temperature detecting point on controller switching equipment.
Further, controller switching equipment excess temperature indicator of the present utility model, described temperature detect switch (TDS) of often opening is adjustablely often drive temperature detect switch (TDS), and described adjustable temperature detect switch (TDS) of often opening is provided with temperature adjustment knob.
Further, controller switching equipment excess temperature indicator of the present utility model, is also in series with a shift knob between described battery and LED.
Further, controller switching equipment excess temperature indicator of the present utility model, described LED is red LED lamp.
The beneficial effect that the utility model obtains is: (1) structure is simple, low cost of manufacture; (2) when the temperature detecting point on controller switching equipment temperature higher than setting temperature time, temperature detect switch (TDS) will close automatically, thus by whole circuit turn-on, LED will be luminous, thus the temperature indicating this temperature detecting point is too high, so that maintainer overhauls controller switching equipment in time; (3) temperature detect switch (TDS) is adjustablely often drive temperature detect switch (TDS), is provided with temperature adjustment knob, is thus convenient to adjust the design temperature of temperature detecting point; (4) be also in series with a shift knob between battery and LED, thus can open fast as required or cut off whole circuit; (5) LED is red LED lamp, and thus pilot light is more eye-catching, more easily causes the attention of maintainer.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present utility model.
In figure: 1, battery, 2, divider resistance, 3, temperature detect switch (TDS), 4, LED, 5, shift knob.
Embodiment
As shown in Figure 1, controller switching equipment excess temperature indicator of the present utility model, the LED 4 comprising battery 1, temperature detect switch (TDS) 3, divider resistance 2 and indicate, described battery 1, temperature detect switch (TDS) 3, divider resistance 2 and LED 4 are in series, described temperature detect switch (TDS) 3 is provided with temperature sense sheet, described temperature sense sheet is connected with the temperature detecting point on controller switching equipment, and described temperature detect switch (TDS) 3 is adjustable temperature detect switch (TDS) of often opening, and described adjustable temperature detect switch (TDS) of often opening is provided with temperature adjustment knob; A shift knob 5 is also in series with between described battery 1 and LED 4; Described LED 4 is red LED lamp.
Controller switching equipment excess temperature indicator of the present utility model, structure is simple, low cost of manufacture, when the temperature detecting point on controller switching equipment temperature higher than setting temperature time, temperature detect switch (TDS) 3 will close automatically, thus by whole circuit turn-on, LED 4 will be luminous, thus the temperature indicating this temperature detecting point is too high, so that maintainer overhauls controller switching equipment in time.
Temperature detect switch (TDS) 3 is adjustable temperature detect switch (TDS) of often opening, and is provided with temperature adjustment knob, is thus convenient to adjust the design temperature of temperature detecting point.
Also be in series with a shift knob 5 between battery 1 and LED 4, thus can open fast as required or cut off whole circuit.
LED 4 is red LED lamp, and thus pilot light is more eye-catching, more easily causes the attention of maintainer.
