High voltage metering cabinet is an electrical energy metering device used in power systems, usually installed in high-voltage distribution systems to measure and record the consumption of electrical energy.
Definition and purpose:
High voltage metering cabinet, also known as high-voltage electrical energy metering device, is a specialized electrical energy metering equipment used in 50-60Hz AC three-phase system networks.
It achieves precise measurement and recording of electrical energy in high-voltage power systems by combining components such as transformers and instrument boxes, providing accurate basis for electricity bill settlement.
Structure and composition:
High voltage metering cabinets are usually composed of primary electrical equipment such as high-voltage voltage transformers, high-voltage current transformers, and high-voltage live displays, as well as secondary electrical equipment such as active energy meters and reactive energy meters.
The cabinet structure is sturdy and has strong protective performance, ensuring stable operation of the equipment in harsh environments.
Functional features:
Equipped with data collection function, it can read meters in real time and conduct electricity statistics.
Equipped with distribution monitoring function, it can view real-time load active power, reactive power, voltage, current and other electrical parameters and curve graphs.
Some high-voltage metering cabinets also have functions such as load breaking, microcomputer protection, prepayment, anti-theft, mechanical locking of isolating switches and grounding switches.
Application scenarios:
High voltage metering cabinets are widely used in high-voltage power systems such as power plants, substations, and industrial and mining enterprises to measure and record the consumption of electrical energy.
In situations where precise measurement of electrical energy is required for electricity bill settlement, the role of high-voltage metering cabinets is important.
