                                  產品詳情

                                  產品概述 Product overview

                                  GZDW 系列直流屏用鎘鎳電池、浮充電機、配置自動檢測報警裝置,具有使用壽命長、無污染、維護方便、電壓穩定、超低內阻輸出、承受大電流沖擊及適應性強、可靠性高等特點,是一種較為優良的直流操作電源裝置,可廣泛應用于 500kV 及以下的變配電所及以下的電廠,也可應用于冶金、礦山、石油、廣播電視、計算機房、地下鐵道、高層建筑等部門,作為直流控制、信號電源、斷電保護和斷路器操作機構分合閘電源。 

                                  本產品符合 JB/T5777.4-2000《電力系統直流電源設備通用技術條件及安全要求》標準。 

                                  GZDW series Cd-Ni batteries for DC screens, floating charge motors and automatic detection and alarm devices are characterized by long service life, no pollution, convenient maintenance, stable voltage, ultra-low internal resistance output, strong adaptability and high reliability. They are ideal DC operation power supply devices. They can be widely used in power plants below 500kV and power plants below 500 kV, as well as in departments such as metallurgy, mining, petroleum, radio and television, computer room, underground railway, high-rise buildings, etc. They can be used as DC control, signal power supply, power cut-off protection and on/off power supply for breaker operating mechanisms. 

                                  This product complies with JB/T5777.4-2000《general technical conditions and safety requirements for DC power supply equipment in power system》.

                                  結構特點 Design feature 

                                  微機控制的雙路交流輸入可自動轉換; 

                                  交流輸入過欠壓,過流,缺相缺零自動檢測,顯示和報警保護; 

                                  充電和浮充電裝置采用智能高頻開關整流器模塊,N+1 冗余相合,自動均流,并可以帶電插拔; 

                                  蓄電池均充和浮充過程自動轉換,并可按照電腦設置的正常運行。電網解列、恢復送電等程序實現蓄電池智能均浮充管理; 

                                  在微機控制裝置故障或發出錯誤控制指令時,充電模塊進入工作狀態,輸出電壓為出廠設定的安全電壓,保障系統運行的可靠性。 

                                  智能四遙系統針對交流輸入、直流輸出、電池回路以及擴充的環境監測提供詳細的通訊協議,并具備與變電站綜合自動化系統通訊的智能接口。 

                                  Two-way AC input controlled by microcomputer can be automatically converted. 

                                  Automatic detection, display and alarm protection for AC input over/under voltage, over current, phase and zero deficiency; 

                                  The charging and floating charging device adopts an intelligent high-frequency switching rectifier module, N+1 redundancy is combined, automatic current sharing is realized, and the charging and floating charging device can be plugged and unplugged with electricity; 

                                  The battery charging and floating charging processes are automatically switched and can operate normally according to the computer settings. The intelligent floating charge management of storage battery is realized by the procedures of power grid disconnection, power transmission restoration and the like; 

                                  When the microcomputer control device fails or sends out an error control instruction, the charging module enters an autonomous working state, and the output voltage is the factory-set safe voltage to ensure the reliability of the system operation. 

                                  The intelligent four-remote system provides detailed communication protocols for AC input, DC output, battery circuit and expanded environmental monitoring, and has an intelligent interface for communication with the substation integrated automation system.
