三相交流保護繼電器ABJ1-W系列簡介

一、保護特點:

1.過壓.欠壓保護:指被保護線路電壓超出設定值范圍。指示燈形式為黃（下）燈亮。

2.動態斷相靜態斷相保護:指被對象（如壓縮機、電動機）運行狀態或沒有運行狀態中任意一相發生斷相故障。指示燈形式為黃（上）燈亮,并優先。

3. 電壓不平衡保護:指三相電壓不平衡將會引起過載和安全運行的一種電壓不平衡率設定值保護。指示燈形式為黃（上）燈亮,并優先。

4. 錯相保護:防止A.B.C三相交流相序接錯的一種保護措施,即時動作。指示燈形式為紅燈亮 。

5.延時保護:有故障出現時保護繼電器延時幾秒后動作,繼電器釋放。

二、性能特點:

1.欠壓保護時為了防止電壓在負載連接和斷開時的來回跳動，保護繼電器具有回差電壓保護功能，出廠默認欠壓保護回差電壓5VAC。

2.保護繼電器的保護功能不受線路或負載的電流大小.不平衡電流和負載性質的影響。用于電動機保護時對電動機接線方式無要求。

3.保護繼電器能夠全性能.全氣候長期工作。

三、工作特點:

1.A.B.C三相接線正確,保護繼電器綠燈亮,常開觸點14.11吸合;如果相序接錯,保護繼電器紅燈亮,常開觸點14.11斷開;只要交換A.B.C三相中的任意兩相,保護繼電器就能認定該相序并正常工作。當被保護的線路正常工作后出現紅燈亮.繼電器不吸合時,應視為外線路相序誤接,保護繼電器具有防誤接保護功能。

2.A.B.C.過壓或欠壓黃（下）燈亮,綠燈不亮.常開觸點14.11斷開,電壓正常后常開觸點14.11吸合。

3.A.B.C.接三相交流電壓;14.11為常開觸點;11.12為常閉觸點。使用U型接線片或導線連接接線端子。

Three-phase AC protection relay ABJ1-W Series Overview

1, protection features: 
1. Overvoltage. Undervoltage protection: means the protection circuit voltage beyond the set value range. Indicator light in the form of yellow (bottom) lights. 
2. Dynamic-phase-phase static protection: means the objects (such as compressors, motors) running or not running the state of any one phase-phase fault occurs. Indicator light in the form of yellow (top) lights, and give priority to. 
3. Voltage unbalance protection: means the three-phase voltage unbalance will cause overload and safe operation of a voltage imbalance in the rate of protection settings. Indicator light in the form of yellow (top) lights, and give priority to. 
4. Wrong phase protection: to prevent three-phase AC phase sequence ABC pick the wrong one protection measures, immediate action. Indicator in the form of red light. 
5. Delay Protection: Protection relay malfunctioning occurs, after a few seconds delay action relay to release. 
2, performance characteristics: 
1. Undervoltage protection order to prevent the voltage at the load connect and disconnect bounce back and forth when the protection relay with hysteresis voltage protection, undervoltage protection back to the factory default voltage difference 5VAC. 
2. Protection of relay protection function from the current size of the line or load. Unbalance current and load properties. Protection for the motor wiring to the motor did not ask. 
3. Protection relay to the whole performance. All-weather long-term work. 
Third, work characteristics: 
1.ABC three-phase wiring is correct, the protection relay green light, normally open contacts 14.11 Pick-up; If you pick the wrong phase sequence protection relay red light, normally open contact 14.11 disconnect; so long as the exchange of any of the three-phase ABC two-phase protection relay will be able to identify the phase sequence and working properly. When the line to protect the red light after work. Relay not to breathe timely, shall be deemed wrong phase sequence outside the line access, protection relays wrong with anti-pick protection. 
2.ABC overvoltage or undervoltage yellow (below) lights green light does not shine. Normally Open contact 14.11 off, the voltage to normal pull-14.11 Normally Open contact.
