Embodiment Construction

[0014] The present invention will be further described below in conjunction with drawings and embodiments.

[0015] Such as figure 1 As mentioned above, the present invention includes a nut 1 and a stud 2. The bottom of the nut 1 extends out of the stud 2. The top of the nut 1 is provided with a counterbore 11. One end of the temperature measuring element 3 is inserted into the counterbore 11 and fixed with glue. The temperature measuring element 3 is a temperature sensor. The temperature sensor can be a wired temperature sensor or a wireless temperature sensor. One end of the temperature sensor is inserted into the counterbore 11, and the temperature sensor converts the detected temperature signal into an electrical signal. When a wired temperature sensor is used, the other end of the wired temperature sensor is connected to the temperature measurement module through a wire; when a wireless temperature sensor is used, the temperature signal is converted into an electrical sig...

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 [0001] The invention relates to a temperature measuring device, in particular to a device for detecting the temperature of copper bars connected in a power distribution cabinet, belonging to the technical field of power supply and distribution equipment. Background technique [0002] A circuit breaker is an electrical protection device installed between a power supply and a load unit to protect motors, transformers, and load units of power transmission lines from accidents caused by large currents in power transmission lines caused by short circuits or ground faults. Usually, the static and dynamic contacts of the circuit breaker are connected with the power supply and load unit through conductive copper bars. The conductive copper bars work under high current and heavy load conditions for a long time, and the joints are exposed to the air. Metal oxidation and air Influenced by environmental factors such as dust and oil pollution in the environment, the resis...
