Abstract

The utility model discloses a temperature-measuring screw bolt which comprises a screw cap and a screw stud, wherein the screw stud extends out of the bottom of the screw cap. The temperature-measuring screw bolt further comprises a temperature-measuring element, wherein a counter bore is formed at the top of the screw cap, one end of the temperature-measuring element is fixed in the counter bore, and the temperature-measuring element is a wired temperature sensor or a wireless temperature sensor. When the temperature-measuring screw bolt is mounted on a conductive copper bar at joints at two ends of a circuit breaker, and the temperature of the conductive copper bar rises, the temperature sensor converts a detected temperature signal to an electrical signal and further conducts or transmits the electrical signal into a power distribution cabinet or an external temperature-measuring module, and if the detected temperature value exceeds the set safe temperature, the temperature-measuring module emits a signal for audible and visual alarm, thereby facilitating the timely overhaul of the copper bar of overhaul staff and ensure the normal running of a whole power system. The utility model has the advantages of simple structure, convenient maintenance, disassembly and assembly, low cost, and high detection precision.

Description

A kind of temperature-measuring bolt
Technical field
The utility model relates to a kind of temperature measuring equipment, and 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.
The utility model content
The purpose of this utility model provides a kind of simple in structure, maintenance easy accessibility, temperature-measuring bolt that accuracy of detection is high, and 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 utility model 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.
The purpose of this utility model 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 utility model 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 utility model is installed in the joint of other transmission lines of electricity also can play same effect.
Advantage of the present utility model 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 utility model;
Fig. 2 is the mounting structure synoptic diagram of the utility model embodiment one.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As described in Figure 1, the utility model comprises nut 1, double-screw bolt 2, and 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 utility model is installed on the three-phase copper bar 5 of joint, isolating switch 4 two ends, and temperature sensor adopts wired temperature sensor, model is DS18B20, 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 utility model also can be installed in the terminal place of other transmission lines of electricity.
