Abstract
The utility model discloses a plug-in type multipoint temperature measuring device for power cables, and relates to the cable temperature measurement technology field. The device comprises a temperature signal transmission line, one end of which is connected with a temperature measuring probe and the other end of which is connected with an earphone plug, wherein a temperature variation signal of the temperature measuring probe is transmitted to a temperature measurement instrument through the earphone plug. The plug-in type multipoint temperature measuring device has the advantages that only one temperature measurement instrument is needed to be installed, only a temperature sensor is installed at some position of paralleled power cables through the temperature signal transmission line, and therefore the temperature variation at the position of the paralleled power cables can be detected conveniently; and the plug-in type multipoint temperature measuring device is simple in structure, amount of temperature measurement instruments used is decreased, and money is saved.
Description
Technical field
The utility model relates to a kind of cable thermometry field, specifically a kind of plug-in type multiple spot power cable temperature measuring equipment; For detection of power cable a part skin temperature variation.
Background technology
The temperature measuring equipment that the variation of online detection power cable a part skin temperature is adopted usually is that a temperature sensor is installed on every power cable, heating causes that skin temperature raises after the cable energising, pass to temperature sensor, then by temperature sensor, temperature variation is passed to measurement instrument.In this way or device detect the skin temperature of each power cable, a temperature sensor and corresponding signal processing apparatus must be installed on every cable, cause production cost to increase, if several cables are arranged on a certain power circuit, several sensors and several device for signalling to be installed.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of plug-in type multiple spot power cable temperature measuring equipment, and can detecting easily herein, Temperature of Power Cables changes.
The utility model is realized with following technical scheme: a kind of plug-in type multiple spot power cable temperature measuring equipment, comprise a temperature signal transmission line, and one of the temperature signal transmission line connects temperature probe, other end frames connecting with headphone plug; On temperature probe, the temperature variation signal is sent on temperature instrumentation by headset plug.
Described temperature probe adopts temperature sensor 18B20, described headset plug adopts the dual sound track plug for earphone structure, headset plug is provided with temperature sensor 18B20 power supply ground end, temperature sensor 18B20 digital signal I/O end and the external power supply input end of temperature sensor 18B20, and temperature instrumentation is provided with 8 earphone jacks that match with headset plug.
The beneficial effects of the utility model are: when needs during at a several Temperature of Power Cables of area monitoring, only need to install a temperature detection instrument, by the temperature signal transmission line, a temperature sensor is installed in these power cables arranged side by side a part and Temperature of Power Cables variation herein just can be detected easily; Simple in structure, can reduce the usage quantity of temperature measuring device, reduce investment outlay.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model structural representation.
In figure: 1, temperature instrumentation, 2, earphone jack, 3, temperature sensor 18B20 power supply ground end, 4, temperature sensor 18B20 digital signal I/O end, 5, the external power supply input end of temperature sensor 18B20,6, the temperature signal transmission line, 7, temperature probe.
Embodiment
As shown in Figure 1, plug-in type multiple spot power cable temperature measuring equipment has a temperature signal transmission line 6, and one of temperature signal transmission line 6 connects temperature probe 7, other end frames connecting with headphone plug; On temperature probe 7, the temperature variation signal is sent on temperature instrumentation 1 by headset plug.Certain or many places at the power cable of the whole circuit that transmits electric power are close to temperature signal transmission line temperature probe 7 on power cable with snap ring or the mode of tying up.
In the present embodiment, described temperature probe 7 adopts temperature sensor 18B20, described headset plug adopts the dual sound track plug for earphone structure, headset plug is provided with temperature sensor 18B20 power supply ground end 3, temperature sensor 18B20 digital signal I/O end 4 and the external power supply input end 5 of temperature sensor 18B20, and temperature instrumentation 1 is provided with 8 earphone jacks 2 that match with headset plug.Can connect 8 temperature signal transmission lines, just be known the temperature variation of a part that temperature probe is installed on power cable by the indication of the temperature on temperature measuring device (or demonstration).
During power cable was carried electricity, the skin temperature rising that the abnormal conditions adstante febre can cause power cable appearred in certain root in power cable or a part of whole power cable.Because temperature probe 7 is close on power cable, therefore the rising meeting of power cable skin temperature is passed to temperature probe 7 with heat, this temperature variation is sent to temperature variation signal on temperature probe 7 on temperature instrumentation 1 by temperature signal transmission line 6 again, can in time reflect contact power cable position temperature situation from the numeral of temperature instrumentation 1 indication (or demonstration), illustrate that simultaneously this temperature measuring equipment can obtain the temperature variation data of a place on power cable or many places at any time.
