>>>>>型號(hào):469-P1-HI-A20-E 控制電源型號(hào) 大型電機(jī)系統(tǒng)
【功能描述】
GE Multilin 469 系列的這種增強(qiáng)型號(hào)能夠保護(hù)和控制中型到大型電機(jī)系統(tǒng)。469-P1-HI-A20-E-H 與大多數(shù)型號(hào)不同，它帶有可選的保形涂層;這種薄的聚合物層有助于保護(hù)設(shè)備免受灰塵、高溫等的影響。因此，保形涂層延長(zhǎng)了電機(jī)壽命，尤其是在危險(xiǎn)的操作環(huán)境中。
469-P1-HI-A20-E-H 的增強(qiáng)型面板可分為大約四個(gè)部分：包括用于直接連接到運(yùn)行 EnerVista 469 的筆記本電腦的 RS232 端口、用于輸入和編輯設(shè)定值的重新設(shè)計(jì)的鍵盤、擴(kuò)展的 40 字符液晶顯示屏以及表示系統(tǒng)內(nèi)各種狀態(tài)的 LED。
1-P1-HI-A469-E-H 型號(hào)中的“P20”表示繼電器與 1 A 相 CT 次級(jí)兼容。與以“P5”型號(hào)表示的 5 A 相 CT 次級(jí)相比，用戶應(yīng)確保標(biāo)稱相電流額定值與所有連接的 CT 的連接和次級(jí)額定值相對(duì)應(yīng)。 不匹配的 CT 會(huì)隨著時(shí)間的推移對(duì)系統(tǒng)造成損壞，并且即使這種損壞不會(huì)立即變得明顯，也無(wú)疑會(huì)導(dǎo)致保護(hù)減弱。
該繼電器還能夠進(jìn)行自我評(píng)估，評(píng)估電機(jī)健康狀況，并提供可配置的警報(bào)，以便在出現(xiàn)轉(zhuǎn)子問(wèn)題時(shí)提醒用戶。 這種早期檢測(cè)系統(tǒng)除了減少停機(jī)時(shí)間外，還縮短了故障排除時(shí)間。與電機(jī)健康相關(guān)的指標(biāo)也可以在通用電氣 Multilin 的 EnerVista 469 程序中查看，這比使用鍵盤手動(dòng)瀏覽繼電器的菜單更有效。

【英文介紹】
This enhanced version of the GE Multilin 469 series protects and controls medium to large motor systems. 469-P1-HI-A20-E-H Unlike most models, it comes with an optional conformal coating; This thin polymer layer helps protect the device from dust, heat, and more. As a result, conformal coatings extend motor life, especially in hazardous operating environments.
The 469-P1-HI-A20-E-H enhanced panel can be divided into approximately four parts: Includes an RS232 port for connecting directly to a laptop running EnerVista 469, a redesigned keyboard for entering and editing Settings, an expanded 40-character LCD display, and leds for indicating various states within the system.
The "P20" in the 1-P1-HI-A469-E-H model indicates that the relay is compatible with the 1 A-phase CT secondary. In contrast to the 5 A phase CT secondary indicated by the "P5" model, the user should ensure that the nominal phase current rating corresponds to the connection and secondary ratings of all connected CTS. Mismatched CT can cause damage to the system over time, and even if this damage does not become immediately apparent, it will undoubtedly lead to weakened protection.
The relay is also capable of self-assessment, assessing motor health and providing configurable alarms to alert the user if there is a rotor problem. In addition to reducing downtime, this early detection system also reduces troubleshooting time. Indicators related to motor health can also be viewed in GE Multilin's EnerVista 469 program, which is more efficient than manually navigating the relays' menus using a keyboard.
