Description

Technical Field

[0001] The invention belongs to the technical field of electric energy metering boxes, in particular to an electric energy metering box with a security structure. Background Art

[0002] The electric energy meter box is a combination of metering instruments and auxiliary equipment necessary for measuring electric energy. It includes electric energy meters, voltage and current transformers for measurement and their secondary circuits, electric energy metering panels, cabinets, boxes, etc. It plays an important role in electric energy measurement and management.

[0003] The energy meter is a precision measuring instrument whose working principle and performance may be affected by the ambient temperature: (1) For electronic energy meters, temperature changes may affect the performance of electronic components, such as resistance and capacitance, and thus affect the measurement accuracy. High or low temperatures may cause changes in the parameters of electronic components, resulting in measurement errors; (2) For traditional electromechanical energy meters, temperature changes may affect the wear of mechanical parts, the state of lubricating oil, and the performance of coils, all of which may affect the accuracy of the energy meter; (3) At extreme temperatures, the error of the energy meter may increase. For example, an increase in temperature may cause the energy meter to run faster, resulting in overcounting; while at low temperatures, the energy meter may run slower, resulting in undercounting.

[0004] In order to ensure the accurate counting of the energy meter, the energy meter usually has a calibrated operating temperature range, for example, usually between -25℃ and 55℃. Within this temperature range, the performance and accuracy of the energy meter can be guaranteed. If the ambient temperature exceeds this range, it may be necessary to calibrate the energy meter or take appropriate temperature control measures.

[0005] Therefore, when installing and using the electricity meter, the influence of ambient temperature should be considered to ensure that it operates within an appropriate temperature range to ensure the accuracy of measurement.

[0006] At present, the electric energy meter boxes are all provided with heat dissipation holes on the side walls of the box body, so as to dissipate the heat generated in the electric energy meter as quickly as possible and avoid affecting the electric energy meter in the electric energy meter box. However, the heat dissipation requirements are different for different regions and seasons, and the heat dissipation holes on the current electric energy meter boxes are all fixed in opening size, which cannot be adaptively adjusted according to external factors such as regions and seasons.
