產品概述 Product overview

XHLX-PV 智能光伏直流匯流箱是將 24 路光伏電池組件串的直流輸入匯流合成 1 路或多路輸出，每路配熔斷絲，輸出配備防雷器和斷路器，大大簡化了直流配電柜及逆變器的輸入接線。提供防雷保護，短路保護和接地保護。匯流箱分為智能和非智能兩種類型。智能直流匯流箱內部裝有匯流監測單元，能監測每路光伏電池串輸入的電流、匯總輸出電壓、箱體內的溫度及防雷器狀態、斷路器狀態等。 

該裝置內部布置簡潔明了，布線整齊合理。可靠性高，維護簡單。戶外壁掛式安裝，能適應各種惡劣環境。除了相關核心元器件外，其他可按用戶要求定制。

XHLX-PV Intelligent Photovoltaic Lightning Protection Junction Box combines DC inputs of up to 24 photovoltaic cell module strings into one or more outputs, each of which is equipped with fuse, and the output is equipped with lightning protector and circuit breaker, greatly simplifying the input wiring of DC power distribution cabinet and inverter. Provide lightning protection, short circuit protection and grounding protection. The junction box is divided into intelligent and non-intelligent types. The intelligent lightning protection junction box is internally provided with a junction monitoring unit, which can monitor the current input by each photovoltaic cell string, summarize the output voltage, the temperature in the box, the state of the lightning protector, the state of the circuit breaker, etc. 

The internal arrangement of the device is simple and clear, and the wiring is neat and reasonable. High reliability and simple maintenance. Outdoor wall-mounted installation can adapt to various harsh environments. In addition to related core components, other components can be customized according to user requirements.

功能特點 Functional characteristics

匯流箱的防護等級達到 IP65，具備防水、防灰、防銹、防鹽霧，滿足室外安裝的要求； 

可同時接人多至 24 路電池串列； 

每路電池串列的正負都配有光伏專用熔絲，對組件串出現故障時進行保護，熔斷器底座及熔絲配套使用，減少業主后期維護成本，有效保護維修人員的人身安全； 

采用光伏專用高壓防雷器能對匯流后的母線正對地、負對地進行保護，持續工作電 ( Uc) 可達到 1000VDC； 

匯流箱內的電源模塊能夠接入 1000DCV 的光伏電壓； 

匯流箱測控模塊采用性能可靠的霍尼韋爾霍爾元件（直流 CT 傳感器），對每一路光伏組串進行電流、母線電壓進行采集監測、報警和本地故障定位，并能對匯流箱內的溫度進行測量，防雷器及輸出斷路器的狀態檢測等； 

匯流箱內的監測模塊具備數碼顯示功能，能在設備上顯示每串組件串的電流，母線電壓，匯流箱內的溫度，斷路器防雷器的狀態，系統功率及設備地址等相關信息； 

具備 RS485/MODBUS-RTU 串口通信； 

與外部接口部分均有防雷保護； 

能接收本地監控裝置的參數下載，進行分析處理； 

匯流箱工作電源可選擇外界 220VAC/DC 或者由匯流箱本身提供的電源供電，如果采用匯流箱本身提供電源，現場可以不需要針對供電、單獨布線。 

The protection grade of the junction box reaches IP65, which is waterproof, ash-proof, rust-proof and salt fog-proof, and meets the requirements of outdoor installation. 

Up to 24 battery strings can be connected simultaneously; 

The positive and negative poles of each battery string are equipped with photovoltaic special fuses to protect the aZLembly string in case of failure. The fuse base and fuses are used together to reduce the later maintenance cost of the owner and effectively protect the personal safety of maintenance personnel. 

The adoption of photovoltaic special high-voltage lightning protector can protect the bus positive pole to ground and the bus negative pole to ground after bus convergence, and the continuous working power (Uc) can reach 1000VDC；. 

The power supply module in the bus box can be connected with photovoltaic voltage up to 1000DCV; 

The bus box measurement and control module adopts Honeywell Hall element (DC CT sensor) with reliable performance to collect and monitor current and bus voltage of each photovoltaic group string, alarm and locate local faults, and can measure the temperature in the bus box, detect the status of lightning arresters and output circuit breakers, etc. 

The monitoring module in the bus box has a digital display function, which can display the current, bus voltage, temperature in the bus box, status of breaker lightning protector, system power, equipment addreZL and other relevant information on the equipment. 

With RS485/MODBUS-RTU serial port communication; 

Lightning protection is provided for the external interface parts; 

Can receive the parameter download of the local monitoring device for analysis and proceZLing; 

The working power supply of the bus box can be selected from the outside 220VAC/DC or the power supplied by the bus box itself. If the bus box itself is used to supply power, there is no need for separate wiring for power supply on site.
