Description

Technical Field

[0001] This utility model belongs to the technical field of single-phase energy meters, specifically, it relates to a single-phase energy meter with UPS power detection. Background Technology

[0002] Electricity metering is a crucial component of the power system, directly impacting the operating costs of power companies and the accuracy of electricity bill calculations for users. As key equipment for measuring electricity consumption, the electricity meter plays a central role in the power system. Depending on the power supply system, electricity meters are classified into various types, including single-phase meters. In recent years, with the development of smart grids and technological advancements, the functions of electricity meters have been continuously expanded and improved.

[0003] A single-phase energy meter is an instrument used to measure the electrical energy consumption in a single-phase AC circuit. It is the most common type in residential and small commercial environments because these locations typically use single-phase power supply systems. A single-phase energy meter generally includes a current sensor, a voltage sensor, a data processing unit, and a display screen. It calculates electrical energy consumption by measuring the current and voltage in the circuit and displays the results on the meter panel.

[0004] With technological advancements, a new type of single-phase energy meter with special functions has emerged on the market—the energy meter with uninterruptible power supply (UPS) detection. In addition to basic energy metering, this type of meter can monitor the UPS power supply status in real time, which is crucial for ensuring the continuity and reliability of power supply. When the main power supply fails, the UPS automatically starts, using its internal batteries to power critical loads, ensuring that critical equipment does not stop operating due to power outages. Single-phase energy meters with UPS power supply detection can monitor the UPS's operating status in real time, and once an anomaly is detected, it can promptly issue an alarm, helping users take swift action to avoid potential risks.

[0005] While single-phase electricity meters with UPS power detection provide additional safety, their larger size compared to ordinary single-phase meters is due to the integration of more electronic components and complex circuits. Therefore, these meters have stricter requirements for installation location. In actual installation, in confined spaces or structurally complex locations, such as renovation projects in old residential or commercial buildings, unsuitable installation locations often arise. In such cases, due to the size limitations of the meter itself, the installation location must be changed, which not only increases the difficulty of installation but may also lead to additional costs and inconvenience for users.

[0025] Furthermore, the top height of the vertical support frame is equal to the sum of the top height of the electricity meter casing and the height of the bolts.

[0026] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting the height of the vertical support frame to be greater than the height of the electricity meter casing, it is convenient to fix the height of the first bracket.

[0027] Furthermore, the cross-sectional shape of the first bracket is a square tube with recesses on both sides, and the square tube has recesses at both ends. The cross-section of the vertical support frame is a C-shaped tube with inward protrusions at both ends, and the protrusions fit exactly into the recesses at both ends of the first bracket.
