Problems solved by technology

In 2019, the construction of the ubiquitous power Internet of Things will be deployed. So far, there are no special test instruments and standardized inspection methods for the temperature and humidity sensors of the Internet of Things for power equipment.
The disadvantage of the existing measurement and detection sensors is that the measurement time is long, because the heating and humidification in the box, the heating space is large, the response of the measured sensor and the sensor for comparison is relatively slow, and it takes several minutes to set and more than ten minutes to make the temperature of the equipment approximately The second is to add humidity to the overall equipment, which may affect the life cycle of other equipment and cause greater damage to the equipment

Embodiment Construction

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 and figure 2 As shown, a clamping device for verifying temperature and humidity sensors of the Internet of Things for power equipment of the present invention includes a handle 13, a clip 14, a connecting shaft 15, and a shrapnel 16, wherein two handles 13 are connected by a connecting shaft 15, and the clip 14 is connected to the handle 13 is integrally arranged, and the shrapnel 16 is clamped between the two handles 13, so that when the handle 13 is pressed down firmly, the two clips 14 are opened, and the tested sensor 9 and the high-precision temperature and humidity sensor 10 (the present invention) can be respectively Compared with the tested sensor 9, the high-precision temperature and humidity sensor 10 is generally an order of magnitude higher than the tested sensor 9. If the temperature accuracy of the test...

Abstract

The invention relates to the technical field of electric infrastructure, and in particular relates to a calibration and clamping device and a calibration method for the temperature and humidity sensorof the Internet of Things of electric equipment. The clamp provided by the invention is divided into a left clamp, a right clamp and a nozzle window. The left clamp and the right clamp are located onboth sides of the nozzle window respectively. The nozzle window is a hollow cavity. The left clamp and the right clamp are semi-sealed. According to the invention, a tested sensor and a high-precision temperature and humidity sensor are arranged in a small enclosed space, so that the temperature and humidity rise rapidly; and the temperature and humidity changes of two sensors are consistent, thereby improving the test accuracy.

Description

technical field [0001] The invention relates to the technical field of electric power infrastructure, in particular to a verification clamping device and a verification method for a temperature and humidity sensor of the Internet of Things of power equipment. Background technique [0002] According to the development needs of the power industry, the State Grid Corporation of China has proposed the strategic goal of "three types, two networks, and world-class", comprehensively deploying and promoting the construction of the ubiquitous power Internet of Things, and empowering traditional power grids with informatization, digitalization, and modernization. Since 2019, in order to comprehensively perceive the status of power equipment and obtain environmental parameters in real time, a large number of IoT sensors for power equipment have been put into use. A wireless temperature and humidity sensor is installed. If the temperature and humidity sensor fails, the temperature and ...
