Embodiment Construction

[0026] The temperature control device of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] As shown in Figure 1, the temperature control device of the present invention is mainly made up of thermistor 2, control circuit 3, power management unit 4 and heating refrigerator 5, and control circuit 3 is connected with thermistor 2 and heating refrigerator 5 respectively, The power management unit 4 is connected with the control circuit 3 and introduces the power signal in the meter device 1 into the control circuit 3 .

[0028] figure 2 The Rth in Rth is an inductive element, specifically a thermistor (PTC), whose resistance value changes linearly in direct proportion to the temperature, that is, as the temperature rises, the resistance value becomes larger; when the temperature drops, the resistance value decreases. The thermistor 2 is connected to the control circuit 3 , and the information of its resistance v...

Abstract

The invention relates to a smart meter equipment-based temperature control device, which comprises a thermistor 2, a control circuit 3, a power supply management 4 and a heating cooler 5, wherein the control circuit 3 is connected with the thermistor 2 and the heating cooler 5 respectively; the power supply management 4 is connected with the control circuit 3 and conducts the power supply signal of meter equipment 1 to the control circuit 3; and the control circuit 3 analyzes and processes the temperature information transmitted by the thermistor 2 and sends a control signal to the heating cooler 5. The temperature control device controls the temperature of the working environment of the meter equipment and keeps temperature of the working environment of the meter equipment in a reasonable range, thereby greatly improving the stability and reliability of the meter equipment.

Description

technical field [0001] The invention relates to a temperature control device, in particular to a temperature control device based on smart electric meter equipment. Background technique [0002] In the power system, due to the large regional differences in the working environment of the electric meter equipment, coupled with the temperature difference caused by the season, the temperature of the working environment varies in a wide range, the low temperature can reach below -40 ℃, and the high temperature It can reach above 75°C. Under such a disparity in temperature, the functions, performance, and lifespan of the components in the electric meter equipment will drop sharply, which greatly threatens the reliability, safety, and stability of the entire equipment system. It is because of the existence of these hidden dangers that it is very necessary to add a temperature control device to the meter equipment. [0003] The existing smart meter system generally has not added a...
