>>>>型號:REF620E 饋線保護(hù)和測控裝置 提高通信可靠性

【功能描述】

REF620E是一款饋線保護(hù)和測控裝置，專門用于保護(hù)、控制、測量和監(jiān)視公共和工業(yè)電網(wǎng)，包括輻射、環(huán)形和網(wǎng)狀電網(wǎng)。

REF620E它作為專用饋線保護(hù)裝置，具有廣泛的應(yīng)用場景和多樣的功能特點(diǎn)。

REF620E提供饋線過流和接地故障保護(hù)，這種保護(hù)可應(yīng)用于中性點(diǎn)不接地網(wǎng)絡(luò)和電阻或阻抗中性點(diǎn)接地網(wǎng)絡(luò)，為電網(wǎng)的安全穩(wěn)定運(yùn)行提供了重要保障。此外，利用裝置先進(jìn)的站級間通信功能，REF620E也可以用于環(huán)形網(wǎng)狀配電

網(wǎng)絡(luò)或輻射網(wǎng)絡(luò)保護(hù)，實(shí)現(xiàn)了電網(wǎng)的靈活配置和高效管理。

REF620E具有單母線和雙母線兩種配置可選，每種母線配置又有一個或兩個斷路器及多個開關(guān)裝置配置可選，同時支持大量手動和電動隔離開關(guān)和接地開關(guān)，滿足了不同電網(wǎng)配置的需求。

在通信方面，REF620E通過PRP或HSR規(guī)約在通信故障時為無延時的冗余以太網(wǎng)提供一個可選以太網(wǎng)口或提供一個環(huán)網(wǎng)自愈RSTP通信。這種設(shè)計消除了單點(diǎn)故障影響，提高了通信可靠性，確保電網(wǎng)信息的實(shí)時、準(zhǔn)確傳輸。

REF620E還具有集成在一臺繼電保護(hù)裝置中的保護(hù)、控制、監(jiān)測和管理功能，為公共和工業(yè)配電系統(tǒng)提供了緊湊和通用的方案。其廣泛的保護(hù)和控制功能以及可擴(kuò)展性和廣泛的應(yīng)用性，使用戶可輕松定制配置應(yīng)用程序以滿足具體要求。

總的來說，REF620E是一款功能強(qiáng)大、配置靈活、通信可靠的饋線保護(hù)和測控裝置，適用于各種公共和工業(yè)電網(wǎng)場景，為電網(wǎng)的安全、穩(wěn)定、高效運(yùn)行提供了有力保障。

【英文介紹】

The REF620E is a feeder protection and measurement and control device specifically designed to protect, control, measure and monitor public and industrial power grids, including radiant, ring and mesh grids.

REF620E As a dedicated feeder protection device, it has a wide range of application scenarios and a variety of functional features.

The REF620E provides feeder overcurrent and ground fault protection, which can be applied to neutral ungrounded networks and resistance or impedance neutral ground networks, providing an important guarantee for the

 safe and stable operation of the grid. In addition, the REF620E can also be used for ring mesh distribution network or radiation network protection with the device's advanced interstation communication capabilities, enabling

 flexible configuration and efficient management of the grid.

The REF620E is available in single and dual bus configurations, with one or two circuit breakers and multiple switchgear configurations for each bus configuration, and supports a large number of manual and electric isolation 

switches and ground switches to meet the needs of different grid configurations.

In terms of communication, the REF620E provides an optional Ethernet port for redundant Ethernet without delay or a ring self-healing RSTP communication in the event of a communication failure via PRP or HSR protocols. 

This design eliminates the effect of single point of failure, improves the reliability of communication, and ensures the real-time and accurate transmission of power grid information.

The REF620E also features protection, control, monitoring and management functions integrated into a single relay protection unit, providing a compact and versatile solution for public and industrial power distribution systems.

 Its extensive protection and control capabilities, as well as its extensibility and wide range of applications, make it easy for users to customize and configure applications to meet specific requirements.

Overall, the REF620E is a powerful, flexible and reliable communication feeder protection and measurement and control device for a variety of public and industrial power grid scenarios, providing a strong guarantee for the safe,

 stable and efficient operation of the power grid.
