Description
Product Overview
The Three-Phase Three-Wire Dry-Type Metering Box (Outdoor Epoxy Resin Cast) is an upgraded product developed based on similar products, specifically designed for outdoor power systems with a rated frequency of 50Hz and rated voltages of 10KV and 6KV. It is mainly used for energy metering, providing accurate and reliable energy data for power transmission and distribution. As an ideal replacement for traditional oil-immersed metering boxes, this product solves the defects of oil leakage, high maintenance, and poor environmental adaptability of old-fashioned products, and is widely favored by overseas power engineering and procurement clients.
With an outdoor epoxy resin cast design, the metering box features excellent weather resistance, insulation performance, and durability, making it suitable for long-term stable operation in various outdoor harsh environments. It fully complies with international electrical standards, ensuring safe and efficient energy metering for outdoor power networks.
Product Structure & Composition
The metering box is composed of two main parts: a combined voltage and current transformer, and a metering instrument box. The detailed structure is as follows:
-
Combined Voltage & Current Transformer: The transformer is equipped with two independent voltage transformers and current transformers, which are separately installed in Phase A and Phase C. This reasonable layout ensures accurate measurement of voltage and current, providing reliable signal support for energy metering.
-
Metering Instrument Box: The outer side wall of the combined transformer is equipped with active and reactive watt-hour meters, as well as a joint connection box for testing. During operation, the meter box is covered with a protective cover to prevent electricity theft, ensuring the safety and accuracy of energy metering data.
-
Outdoor Epoxy Resin Cast Design: The entire product adopts an epoxy resin casting process, which integrates the transformer components into a whole, achieving excellent insulation, moisture resistance, dust resistance, and corrosion resistance. It is fully suitable for outdoor long-term operation without the risk of oil leakage.
-
Upgraded & High Performance: Improved based on similar products, with optimized structure and stable performance, effectively solving the common problems of traditional metering boxes and ensuring accurate energy metering for a long time.
-
Ideal Replacement for Oil-Immersed Products: As a dry-type product, it completely replaces old-fashioned oil-immersed metering boxes, avoiding oil leakage, environmental pollution, and high maintenance costs, and reducing operational and procurement costs for users.
-
Outdoor Epoxy Resin Cast: High-quality epoxy resin casting ensures superior insulation performance, strong weather resistance, and adaptability to harsh outdoor environments (high temperature, humidity, dust, corrosion), with a long service life.
-
Three-Phase Three-Wire System: Specially designed for three-phase three-wire outdoor power systems, matching the common power grid structure of most countries and regions, with wide applicability.
-
Anti-Theft Design: The meter box is covered with a protective cover during operation, effectively preventing electricity theft and ensuring the accuracy and safety of energy metering data, reducing economic losses.
-
Easy Installation & Low Maintenance: The integrated structure and reasonable design simplify the installation process, and the dry-type epoxy resin cast design requires no regular maintenance, saving time and labor costs.
-
Accurate Metering: Equipped with high-precision voltage and current transformers, ensuring stable and accurate energy metering, meeting the requirements of power supply departments and industrial and commercial users for energy statistics.
