A fixed-point high-precision temperature measurement device

Abstract

The invention discloses a fixed-point high-precision temperature measuring device, which includes an operating handle, a main body and a sensing part; the sensing part includes a main body spring, a temperature measuring device and a twisting device, and the temperature measuring device is arranged at the end of the main body spring; each twisting device It includes at least three controllable coils, and in the main body spring, at least two turns of the spring are provided with twisting devices; the main body part includes a protective case, a digital display module and a central control module, and the digital display module and the central control module are arranged on the protective case; The operating handle includes a handle and a direction control button, and the direction control button is arranged on the handle; the beginning end of the main body spring and one end of the handle are connected to the protective shell; the temperature measuring device, the controllable coil, the direction control button and the digital display module are electrically connected to the Central control module. The fixed-point high-precision temperature measuring device has the characteristics of high safety in use.

Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to a fixed-point high-precision temperature measurement device. Background technique [0002] At this stage, most of the substations are located in remote mountainous areas, especially in summer. According to the requirements of the operating regulations, in order to ensure the safety of substation equipment and employees, the staff need to conduct special inspections in the substation on a regular basis, and conduct moisture-proof inspections on precision equipment such as mechanism boxes. [0003] When carrying out moisture-proof and anti-fouling operations, the staff need to check whether the heater in the mechanism box is working normally, but for the mechanism box without temperature display and indicator light, it is difficult for the staff to judge the working condition of the heating plate in the mechanism box. The heater for the temperature display and indicator ligh...

Problems solved by technology

[0003] When carrying out moisture-proof and anti-fouling operations, the staff need to check whether the heater in the mechanism box is working normally, but for the mechanism box without temperature display and indicator light, it is difficult for the staff to judge the working condition of the heating plate in the mechanism box. The heater for the temperature display and indicator light will have external air enter the box when the box is opened for inspection, which will affect the temperature inside the box

[0004] When the staff detects the temperature of the heating plate, because there is no suitable detection tool, they use the back of their hands to sense the heat emitted by the heating plate when necessary, which can easily cause accidental touches, resulting in personal accidents such as burns or electric shocks. At the same time, the test results are also inconsistent stability

In addition, due to the inconsistency of the structures in different mechanism boxes and the different installation positions of the mechanism boxes, it is often necessary to avoid other equipment when measuring the temperature of the heating plate. Blocking, can not effectively reach the location of the measured object
