Abstract
The invention discloses a temperature-measuring bolt. The bolt comprises a nut and a stud, wherein the bottom part of the nut extends out of the stud; and the bolt also comprises a temperature-measuring element, the top part of the nut is provided with a counter pore, one end of the temperature-measuring element is fixed in the counter pore, and the temperature-measuring element is a wired temperature sensor or wireless temperature sensor. The temperature-measuring bolt is mounted on an electrically conductive copper bar on joints at each of the two ends of a circuit breaker, when the temperature of the electrically conductive copper bar rises, the temperature sensor converts a measured temperature signal into an electric signal and transfers or emits the electric signal to a temperature-measuring module inside or outside a power distributing cabinet, and when the measured temperature value exceeds a set safety temperature value, the temperature-measuring module gives sound and light alarms, so that maintainers can repair the copper bar in time to guarantee the normal operation of the whole power system. The temperature-measuring bolt has the advantages of simple structure, convenient maintenance and disassembly-assembly, low cost and high measurement precision.
Description
Technical field
The present invention relates to a kind of temperature measuring equipment, especially a kind of being used to detected the device that connects the copper bar temperature in the power distribution cabinet, belongs to the power supplying and distributing equipment technical field.
Background technology
Isolating switch is mounted in the electric protective device between power supply and the load unit, with the load unit of protection motor, transformer and power transmission line, it is avoided in the power transmission lines because the big electric current that short circuit or earth fault cause and accidents caused.Usually, connect by conducting copper between the sound contact of isolating switch and power supply, the load unit, the conducting copper long-term work is under the operating mode of big electric current, big load, and the joint is exposed in the air, and Effect of Environmental such as dust, greasy dirt in the oxidation of metal and the air strengthen the resistance of copper bar connecting portion, temperature raises, shortened the serviceable life of copper bar, can cause that also copper bar burns, and causes the fault of whole electric system when serious.
The patent No. is that 200720121508 Chinese utility model patent discloses the out-of-limit indication bolt of a kind of temperature, this indication bolt is made up of shell and the inner core that is positioned at enclosure, inner tank theca is provided with groove, be fixed with the butterfly shaped dual metal sheet of a thick middle thin edge in the groove, contact the formation screens by extruding between the edge of butterfly shaped dual metal sheet and the outer casing inner wall, inner core is made of stage clip and caution head, and it is inner that stage clip one end is positioned at the caution head; This bolt is installed in the joint of transmission line wire, when the temperature of transmission line wire joint reaches limit value, the butterfly shaped dual metal sheet temperature distortion of indication bolt inside, the extruding stage clip, inner core caution head is subjected to displacement under the stage clip effect, the caution head outwards ejects, thereby is found by the tour personnel, and line conditions is judged.When the temperature at terminal place raise, this utility model can in time detect and report to the police, but its complex structure, maintenance and dismounting inconvenience, and butterfly shaped dual metal sheet is not good enough to the sensitivity of temperature yet.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, maintenance easy accessibility, temperature-measuring bolt that accuracy of detection is high, when the temperature at terminal place raise, this bolt can detect and report to the police in real time, thereby guarantees the normal operation of whole electric system.
The present invention is achieved by the following technical programs:
A kind of temperature-measuring bolt comprises nut, double-screw bolt, and double-screw bolt is extended in described nut bottom, also comprises temperature element, and the top of described nut is provided with counterbore, and an end of described temperature element is fixed in the described counterbore.
Purpose of the present invention can also further realize by following technical measures.
Aforesaid a kind of temperature-measuring bolt, wherein said temperature element are temperature sensor, and described temperature sensor is wired temperature sensor or radio temperature sensor.
Aforesaid a kind of temperature-measuring bolt, the temperature-measuring range of wherein said temperature sensor are-55 ℃～+ 125 ℃, and in-10～+ 85 ℃ of scopes, precision is ± 0.5 ℃.
The present invention is simple in structure, the maintenance easy accessibility, cost is low, accuracy of detection is high; Bore a counterbore earlier at the bolt top, connect isolating switch termination and conducting copper with this bolt then, the end with temperature sensor is fixed in the counterbore on bolt top at last.When the temperature of conducting copper raises, temperature sensor converts detected temperature signal to electrical signal conduction or is transmitted in the power distribution cabinet or outside temperature measurement module, when detected temperature value surpasses the safe temperature of setting, temperature measurement module sender sound and light alarm, make things convenient for the maintainer in time copper bar to be overhauled, avoid it to burn, guarantee the normal operation of whole electric system.When changing temperature sensor, only need it is taken out from the counterbore on bolt top, change new getting final product, convenient and swift.The present invention is installed in the joint of other transmission lines of electricity also can play same effect.
Advantage of the present invention and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structure for amplifying synoptic diagram of the present invention;
Fig. 2 is the mounting structure synoptic diagram of the embodiment of the invention one.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As described in Figure 1, the present invention includes nut 1, double-screw bolt 2, double-screw bolt 2 is extended in nut 1 bottom, and 1 top of nut is provided with counterbore 11, and an end of temperature element 3 inserts counterbore 11, fixes with glue.Temperature element 3 is a temperature sensor, and temperature sensor can be wired temperature sensor, also can be radio temperature sensor, and an end of temperature sensor injects in the counterbore 11, and temperature sensor converts detected temperature signal to electric signal.When adopting wired temperature sensor, wired temperature sensor other end is connected with temperature measurement module by lead; When adopting radio temperature sensor, convert temperature signal to electric signal by wireless transmit and be transmitted in the power distribution cabinet or outside temperature measurement module.
As shown in Figure 2, the present invention is installed on the three-phase copper bar 5 of joint, isolating switch 4 two ends, and temperature sensor adopts wired temperature sensor, and model is DS18B20, and its temperature-measuring range is-55 ℃～+ 125 ℃, and in-10～+ 85 ℃ of scopes, precision is ± 0.5 ℃.The heat that produces when copper bar 5 work conducts to double-screw bolt 2, be fixed on temperature sensor on the double-screw bolt 2 and detect the temperature value of copper bar 5 heats, then detected temperature value being converted to electric signal is transferred to and is arranged in the power distribution cabinet or outside temperature measurement module, when its detected temperature value surpasses the safe temperature value of setting, temperature measurement module sends alerting signal by the warning device sound and light alarm, the connection copper bar that the maintainer just can overhaul in the power distribution cabinet is eliminated fault, avoid burning copper bar 5, guarantee that power supply-distribution system normally moves.
The present invention also can be installed in the terminal place of other transmission lines of electricity.
