LZZW-36 Outdoor Current Transformer nggikan sa Cebuano: LZZW-36 Kasinugalingang Transformer sa Kuryente

Product Overview

Ang casting sa epoxy resin ug insulasyon nga fully enclosed support construction, nag-enclose sa primary & secondary windings ug annular core sa casting body sa epoxy resin. Ang produkto adunay dako nga periphery insulation creepage distance, molihok sa dirtiness ug dampness. Maayo para sa pag-measure sa electric capacity, current ug protective relaying sa power system sa 36kV (Up to 40.5 kV).

Key Features

• 36kV-Class Outdoor High-Voltage Adaptation Design：Ang LZZW-36 outdoor current transformer gipahimo uban sa 36kV rated voltage, nakuha ang insulation levels sa 95kV para sa lightning impulse ug 50kV para sa power frequency withstand voltage. Ito ay may mahigpit na pagsunod sa GB/T 4703.2 ug IEC 60044-2 standards, optimized specifically for outdoor substations, box-type substations, overhead lines, ug uban pang mga scenario nga operante sa 35kV ug mas batas. Ang design sa struktura niini kompleto nga gi consider ang long-term operational demands sa high-voltage outdoor environments, effectively resisting voltage fluctuations ug insulation aging aron mabawasan ang equipment failure risks caused by insulation breakdown, ensuring stable operation of the power system.

• All-Weather Protection Structure：Kini nga produkto adunay dual-protection barrier gikan sa silicone rubber composite insulation materials ug corrosion-resistant aluminum alloy enclosure. Ito ay nakatanggap ng 8,000 oras ng UV aging testing, enduring prolonged outdoor exposure; achieves IP68 protection for continuous operation 1.5 meters underwater, while special structural designs resist 25mm/h snowfall and 15mm ice loads. Verified by 2,500 oras ng salt spray testing, ito ay nag-offer og creepage distance sa 25mm/kV, adapting to diverse harsh outdoor environments such as coastal areas, high-altitude regions, ug cold zones, thereby reducing the impact of climatic factors on device performance.

• Dual-Winding High-Precision Measurement System：Nag-integrate og 0.2S-class metering winding ug 5P20-class protection winding, ang metering winding maintains a ratio error ≤±0.2% within 1%–120% of rated current, meeting high-precision energy metering and line loss analysis requirements. The protection winding exhibits a composite error ≤5% at 20 times rated current with a response time ≤10ms, enabling rapid triggering of relay protection devices to ensure safe disconnection during grid faults. Equipped with two sets of ratio taps (e.g., 400/5A, 600/5A), adjustable via an outdoor-sealed switch without disassembly, it adapts flexibly to varying load currents, enhancing on-site application versatility.

• Intelligent Monitoring & Multi-Mode Communication:Embedded with sensors for temperature (-40°C–+100°C), humidity, and insulation status, the device collects real-time operational data. It supports protocols such as Modbus RTU and IEC 61850-9-2 while retaining a 4–20mA analog output, enabling seamless integration into smart grid monitoring systems or compatibility with traditional monitoring equipment. Through edge computing modules, it locally analyzes data to remotely push early warnings for anomalies, reducing outdoor inspection frequency and operational costs—ideal for intelligent management of remote outdoor equipment.
