GE 469-P5-LO-A20-E

是General Electric Multilin的一款專為大中型電機(jī)設(shè)計(jì)的電機(jī)保護(hù)繼電器，配備增強(qiáng)面板。
這款繼電器本身由DEMO金屬手提箱提供保護(hù)，可以抵抗腐蝕、灰塵和高溫。在發(fā)貨時(shí)，繼電器包裝的寬度為12英寸，高度為11英寸，深度為10英寸，包裹的重量約為十七磅。
GE 469-P5-LO-A20-E電機(jī)保護(hù)繼電器通過(guò)其保護(hù)機(jī)制可以延長(zhǎng)電機(jī)壽命并減少系統(tǒng)停機(jī)時(shí)間。其中一些保護(hù)功能包括過(guò)扭矩保護(hù)和接地故障保護(hù)。
過(guò)扭矩保護(hù)功能可以監(jiān)控扭矩何時(shí)超過(guò)用戶設(shè)置的閾值，并保護(hù)驅(qū)動(dòng)負(fù)載免受損壞。當(dāng)扭矩值達(dá)到用戶設(shè)置的閾值時(shí)，會(huì)分配報(bào)警、跳閘和高位報(bào)警功能。
接地故障保護(hù)功能通過(guò)檢測(cè)危險(xiǎn)電流中的直流分量來(lái)保護(hù)電機(jī)免受相地故障的影響。
此外，GE 469-P5-LO-A20-E還有RTD（Resistance Temperature Detector）保護(hù)功能，這是高度可編程的，可以提醒用戶危險(xiǎn)的環(huán)境溫度變化。當(dāng)值達(dá)到用戶設(shè)置的閾值時(shí)，也可以分配報(bào)警、跳閘和高報(bào)警功能。

It is a motor protection relay designed specifically for large and medium-sized motors by General Electric Multilin, equipped with an enhanced panel.
This relay itself is protected by a DEMO metal suitcase and can resist corrosion, dust, and high temperatures. At the time of shipment, the relay packaging has a width of 12 inches, a height of 11 inches, a depth of 10 inches, and a weight of approximately 17 pounds.
The GE 469-P5-LO-A20-E motor protection relay can extend motor life and reduce system downtime through its protection mechanism. Some of the protection functions include over torque protection and ground fault protection.
The over torque protection function can monitor when the torque exceeds the threshold set by the user and protect the drive load from damage. When the torque value reaches the threshold set by the user, alarm, trip, and high level alarm functions will be assigned.
The ground fault protection function protects the motor from the impact of phase to ground faults by detecting the DC component in hazardous currents.
In addition, the GE 469-P5-LO-A20-E also has a RTD (Resistance Temperature Detector) protection function, which is highly programmable and can alert users to dangerous environmental temperature changes. When the value reaches the threshold set by the user, alarm, trip, and high alarm functions can also be assigned.
