DH - YKS4900 Electrical fire monitoring equipment
The power supply circuit short circuit, long-term overload operation,aged circuit cause leakage current,some part high temperature caused by leakage current,electric arc or electric spark, above mentioned problems may be cause the electrical fire. The residual current electrical fire monitoring system can monitor the change of the residual current continuously for a long time. When residual current is too large, it will alarm and timely points out the alarm parts to find the problem point. It's really have the forewarning function on electric fire.
At present, overload protection circuit breaker is the mainstream electric fire protection products in the market. Its basic function is to accurately and automatically cut off power supply to prevent the overload current which generate heating effect thus to combustion. But its defect is which can't self-adjustment while the rated current be setting, the working line of different rated current must match the overload protection circuit breaker. It can only monitor the current flowing through itself, and it can't monitor the electric leakage of whole working line. Obviously, overload protection circuit breaker can not meet the requirements of electric fire protection.
In China, the mandatory national standards and 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 has compulsory CCCF certificate of Chinese fire protection sector.
Product introduction
DH-YKS4941(independent type)series residual current type electrical fire monitoring detector and temperature measuring type electrical fire monitoring detector(Hereinafter referred to as the detector)The detector use AC220V power supply, and have 2 loop residual current detection signal input and 2 loop temperature detection signal input,2 loop control node output (2 loop current, 2 loop temperature, contact capacity of 3A/250V AC or 3A/30V DC), it can linkage two circuit breakers independently. The detector working steadily and reliable. It not only be used independently,but also realize the alarm at site and control circuit breaker. Control circuit breaker action have manual/automatic two types, automatic type delay time is 1~99s. It can also be connected to the bus of DH-YKS4900 electrical fire monitoring devices and composed a electrical fire monitoring system.
DH-YKS4942 Series residual current electrical fire monitoring detector (Hereinafter referred to as the detector) use AC220V power supply.
With 10 road residual current detection signal input, stable and reliable work. It not only be used independent testing to realize the alarm function. But also be connected to the bus of DH-YKS4900 electrical fire monitoring devices and 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) use AC220V power supply, and have 5 loop residual current detection signal and 5 loop temperature detection signal input, stable and reliable work. It not only be used independent testing to realize the alarm function, but also it be connected to the bus of DH - YKS4900 electrical fire monitoring devices and composed a electrical fire monitoring system.
DH-YKS4941 Configuration(Mutual inductor and temperature sensors)
Setting principles of residual current type electrical fire monitoring detector
The 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 form of 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. Which can 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 detector
Electrical 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
