電流互感器過電壓保護器使用說明書
the instruction manual for the surge protector of current transformer ZY-CTB-X系列 a range of ZY-CTB-X 卓源電氣 ZUOYUAN Electrical 用途 Use ZY-CTB-X電流互感器保護器廣泛應用于電力系統中,用于室內高壓開關柜內電流互感器、戶外電流互感器、箱式變電站內電流互感器等各種安裝電流互感器的場所。 The place where install the ZY-CTB-X current transformer widely used in the electricity system, use for a high-valtage switchboard indoor、The current transforme outdoor、The current transforme in the cabinet type transformer station and so on. ZY-CTB-X保護器應用于CT側的差動繞組、過流繞組、測量繞組、母線保護繞組、備用繞組等。 ZY-CTB-X protective devices is applied in the differential protection of CT、circuit winding、measure winding、bus protection winding、spare winding and so on. 概述 Outlined 電流互感器(CT)在電力系統中,廣泛應用于一次測量與控制,。正常工作時,互感器二次側處于近似短路狀態、輸出電壓很低。在運行中如果二次繞組開路,或一次繞組流過異常電流(如雷電流、諧振過電流、電容充電電流、電感啟動電流等),都會在二次側產生數千伏甚至上萬伏的過電壓。這不僅給二次系統絕緣造成危害,還會使互感器過激而燒損,甚至危及工作人員的生命安全。 The current transformer in the power system,are widely applied in measuring and control. In the normal operation, continuous contract panel of the current transformer be in short-circuit likely, Output voltage is low.if the continuous winding is open or once winding flows abnormal electric current(as the lightning current、resonance oscillation current、battery charging current 、inductance starting current and so so), may produces a thousand volts even ten thousand in the Secondary Transformer. This not only for second time the system causing harm to the insulation,but also endanger the safety of staff. 使用ZY-CTB-X互感器過電壓保護器就能有效的防止因電流互感器二次開路引起的事故。 Use the ZY-CTB-X protection of overvoltage Of instrument transformer can effectively prevent the current transformer secondary open rcause accident 技術指標 technical specifications 1、 正常漏電流the normalleakage current:≤5uA 2、 導電電壓electricity voltageUC:160V±10% 3、 導通時間working time of the switching:Ts:50ms≤Ts≤250ms 4、 遙信繼電器接點容量: the capacity of remote relay contact AC220V/5A,DC220V/2A 5、 保護繼電器接點容量:the capacity of the protection relays.AC250V/10A 6、 使用的CT規格The using of CT specifications:二次側峰值大于150V the second primary side data greater than 150v 7、 外形尺寸Fire emergency luminari:48*48*90(單繞組)simplex winding 145*90*73(2-6繞組)2-6 winding 155*110*110(9-12繞組)9-12winding 8、安裝方式 form of installation;導軌式安裝 the circuit guide installation 主要功能 the primary functions 1、 正常工作時,流入保護器的電流不超過0.1mA,不影響CT正常工作。In the normal working,the electric current flow in protective devices not more than 0.Ma, Not affect the normal work of CT 2、 當A相(或B相,C相)與N相兩端電壓超過160V±10﹪時,CTB裝置就會將A相(或B相,C相)和N相短接。When the voltage above 160v±10 ﹪ if A phase ( or B to C )is with N,the device of CTB can jumpers A phase ( or B to C )is with N 3、 繼電器的接點容量大于6A。所以故障時,能使CT二次側可靠短路。The contacts capacity above 6A, Malfunction can be made CT the second side to be shorted 4、 繼電器接點具有保持功能,按壓“復位”按鈕,才能解除保護。Relays contacts with keeping Press the "clear" button before their protection 5、 裝置提供一對常開接點COM、CK和一對常閉接點COM、CB其中COM為公共端,接點容量5A/220VAC.可接各種聲光報警器或提供給綜合保護裝置是信息遠傳。The device supply a couple of usually open contacts COM、CK and a couple of usually close contacts COM、CB,the COM is public end,the capacity is 5A/220VAC, can connecting with acousto-optic alarm or provides comprehensive protection device that information away from 安裝使用installation using 1、 外形尺寸dimensions 2.接線圖wiring diagram 3、適用方法method 1、把ZY-CTB-X的A(或B/C),N端子并接到CT二次側(圖10) A phase ( or B /C )of the ZY-CTB-X,phase ordered to CT secondary transformer(Figure 10) 2、如果需要把COM或CB或CK連接到其他裝置上 the COM or CB contact to other device if need. 3、若保護工作,則面板上指示燈亮 the light in the panel is bright when the protection is working 4、故障解除后,接壓面板上“復位”按鈕,指示燈滅,故障消失 after clearing the failure , pressing the "clear" button in the panel the indicator light is out, the failure is disappearing 5、若是在斷電情況下排除故障,則不需要操作,掉電后裝置自動復位。When Clearing failure in power failure,that does not need to become any operations , device reset automatically after power failure. |
