Abstract

The embodiment of the invention relates to a temperature detector and a measuring device for detecting the temperature of an electric energy meter terminal base, and the temperature detector comprisesa control module and at least two temperature detection modules, wherein each temperature detection module comprises a temperature collection unit and a temperature sensor. According to the measuringdevice for detecting the temperature of the electric energy meter terminal seat, the temperature acquisition unit acquires signal data of the temperature of the electric energy meter terminal seat through the temperature sensor, and the temperature acquisition unit performs amplification, conversion and ADC encoding processing on cold-end temperature signal data and temperature signal data in thesignal data to obtain temperature codes; the control module converts the temperature code into temperature data taking DEG C as a unit, and the temperature data is subjected to cold short compensation and nonlinear correction of the temperature acquisition unit, so the temperature data of the electric energy meter terminal seat detected by the measuring device for detecting the temperature of theelectric energy meter terminal seat is accurate; the problem of inaccurate temperature data of the detected electric energy meter caused by non-linear and cold junction compensation phenomena of thetemperature sensor of the existing thermocouple is solved.

Description

technical field [0001] The invention relates to the technical field of electric energy meter temperature detection, in particular to a temperature detector and a measuring device for detecting the temperature of a terminal block of an electric energy meter. Background technique [0002] When the electric energy meter is installed and used on site, if the crimping screw on the terminal is not tightened to clamp the wire, or the wire used is too thin, the contact surface is too small and the contact is poor, resulting in a large contact resistance or a circuit current greater than the maximum current of the electric energy meter etc. When the electric energy meter has a large current and runs for a long time, the terminal of the electric energy meter will heat up. In severe cases, the terminal and the electric energy meter will be burned, causing fire, personal injury and other safety accidents. [0003] With the advancement of science, the rapid development of smart energy me...
