Product Name: Residual Current Electrical Fire Monitoring Detector Model NO.: DH-YKS4941 Application: Home, Industry, Communication Electronic Products, Special Equipment, Traffic, Factory Certification: ISO, CCC, Cccf Installation Mode: Wall Mounted Usage: Electrical Fire Monitoring Equipment Type: Electrical Fire Monitoring Detector Trademark: GQ Transport Package: Standard Export Packing Specification: GB Origin: China Product Description DH - YKS4900Electrical fire monitoring equipmentThe power supply circuitshort circuit,long-term overload operation,agedcircuitcauseleakage current,some parthigh temperature caused by leakage current,electric arc or electric spark, above mentioned problemsmay because the electrical fire. The residual current electrical fire monitoring system can monitor thechange of the residual currentcontinuously for a long time.When residual current is toolarge,itwillalarm and timely points out the alarm parts to find the problempoint. It's really have the forewarning functionon electric fire.At present,overload protection circuit breaker is the mainstream electric fire protection productsin the market.Its basic functionis to accurately and automatically cut off power supplytopreventtheoverload currentwhich generateheating effect thus to combustion. But its defect is which can't self-adjustmentwhile the rated currentbe setting, the working line of different rated current must match theoverload protection circuit breaker.It can only monitor the current flowing through itself, and it can't monitor the electric leakageof whole working line.Obviously, overload protection circuit breakercan notmeetthe requirements of electric fire protection.In China, themandatory national standardsand building design specification for fire monitoring products of electric fire protection products is higher than the execution of international standard in the world now. The product hascompulsoryCCCFcertificateofChinese fire protection sector.Product introductionDH-YKS4941(independenttype)series residual current type electrical firemonitoring detector and temperature measuring type electrical firemonitoring detector(Hereinafter referred to as the detector)The detectoruseAC220V power supply, and have 2loopresidual current detection signal input and 2looptemperature detection signal input,2 loopcontrol node output(2 loop current,2 loop temperature, contact capacity of3A/250V AC or 3A/30V DC), it can linkage two circuit breakersindependently. The detectorworking steadilyand reliable. It not onlybe used independently,but also realize the alarm at site and control circuit breaker. Control circuit breaker actionhave manual/automatictwo types, automatic type delay time is 1~99s. It can also be connected to the bus of DH-YKS4900 electrical fire monitoring devicesand composed a electrical fire monitoring system.DH-YKS4942 Series residual current electrical fire monitoring detector(Hereinafter referred to as the detector) useAC220V power supply.With 10 road residual current detection signal input, stable andreliable work. It not onlybe used independent testingto realize the alarm function. But also be connected to the bus of DH-YKS4900 electrical fire monitoring devicesand composed a electrical fire monitoring system.DH-YKS4943 Series residual current type electrical fire monitoring electrical fire detector and temperature measuring type monitoring detector(Hereinafter referred to as the detector) useAC220V power supply, and have 5 loopresidual current detection signal and 5 looptemperature detection signal input, stable and reliable work. It not onlybe used independent testingto realize the alarm function, butalsoitbe connected to the bus of DH - YKS4900 electrical fire monitoring devicesand composed a electrical fire monitoring system.DH-YKS4941 Configuration(Mutual inductorand temperature sensors)ModelMain circuit currentWindow dimension(mm)Outline dimension(mm)CT510100-CA0~60AØ2550(L)×22.3(W)×55(H)CT510200-CB0~100AØ4578(L)×24.2(W)×86(H)CT510300-CC0~160AØ65100(L)×25.3(W)×105(H)CT510400-CD0~225AØ80116(L)×28.5(W)×120(H)CT510500-CE0~400AØ105145(L)×25(W)×150.5(H)CT510600-CF0~630AØ150188(L)×28(W)×194(H)CT510700-CG0~1000AØ200252(L)×33(W)×270(H)ModelMain circuit currentWindow dimension(mm)Outline dimension(mm)CT510800-RA0~100A102×20157(L)×16(W)×50(H)CT510900-RB0~100A100×25174(L)×24.6(W)×70(H)CT511000-RC0~225A150×20206(L)×20(W)×53(H)CT511100-RD0~225A142×32214(L)×28.6(W)×81(H)CT511200-RE0~400A180×35270(L)×28(W)×85(H)CT511300-RF0~630A220×45310(L)×28(W)×95(H)CT511400-RG0~1000A300×45390(L)×28(W)×95(H)CT511500-RH0~1500A400×45495(L)×36(W)×155(H)temperature sensorDetection by testing the temperature of the power supply circuitSetting principles of residual current type electrical fire monitoring detectorThe setting of the residual current type electric fire monitoring detector is based on the principle of terminal detection and it should be set at the end of the total power supply or the end of branch line.The residual current type electric fire monitoring detector alarming parameter value must be set match with the detection of electrical lines appropriate, the detector alarm leakage current is not less than the maximum of 2 times of leakage current of the protection of electrical lines and equipment which under the normal operation.The rated current, rated voltage and other indicators of residual current type electric fire monitoring detector should meet the requirements of the protected line.Earthing formof residual current type electric fire monitoring detector should be mounted as TN-C-S system or TT system of electric power distribution. Residual current type electric fire monitoring detector should be used for alarm. Whichcan cut the power supply only under the situation on protecting the place and equipment without high requirements.The following electrical equipment whithout requirement on residual current type electrical fire monitoring detectorElectrical equipment that uses a safe voltage supplyElectrical equipment with reinforced insulation (double insulation) under normal environmental conditionsElectrical device that uses an isolating transformer and whose secondary is powered by an ungrounded systemElectrical equipment with non-conductive conditions
