An electrical appliance that sends an alarm signal when the residual current exceeds a predetermined value. GB/T 19214 "Residual Current Monitor (RCM) for Electrical Accessories" refers to A series of standards for residual current monitor products is planned to consist of 2 parts. ---Part 1.Residual current monitors for household and similar purposes. The purpose is to specify the performance of RCM for household and similar purposes requirements and test methods and other product-related requirements. ---Part 2.Residual current monitors for industrial use up to 1000VAC. The purpose is to provide for industrial use of RCM Product-related requirements such as performance requirements and test methods. Electrical accessories residual current monitor (RCM) Part 1.Household and similar use surplus Current monitor1 ScopeThis document applies to residual current for household and similar purposes with a rated voltage not exceeding AC 440V and a rated current not exceeding 125A. monitor. This document specifies the classification, characteristics, technical requirements and testing of RCM. Note 1.A standard (IEC 62020-2) for residual current monitors whose rated operating voltage and rated voltage of the circuit being monitored exceeds 440V AC is under consideration. RCM is used to monitor the residual current in the installation and the residual current generated between live parts and exposed conductive parts or ground. An alarm signal is issued when the predetermined value is exceeded. RCM detects suddenly applied or slowly rising residual current in AC circuits (such as AC residual current, pulsating DC residual current current, smooth DC residual current). Note 2.RCM for DC systems is under consideration. This document is applicable to functions that can simultaneously detect residual current, compare the residual current value with the residual operating current value, and the current A monitor that provides a specified alarm signal when the residual current exceeds the residual operating current value. The technical requirements of this document apply to normal environmental conditions (see 7.1). For RCMs used in locations with harsh environmental conditions, it may be necessary to Additional technical requirements are required. RCM is suitable for environments with pollution level 2 and overvoltage category III. For environments with higher pollution levels, it is advisable to use Protection grade casing. RCM conforming to this document applies to TN, TT and IT systems. The RCM involved in this document cannot be used to protect electrical appliances. This document does not cover internal battery powered RCMs. This document does not cover insulation monitors (IMD), which fall within the scope of IEC 61557-8. Note 3.The difference between RCM and IMD is that the monitoring function of RCM is passive and can only respond to the unbalanced fault current of the monitored device. IMD monitoring And the measurement function is active, it can measure the balanced and unbalanced insulation resistance or impedance in the device (see IEC 61557-8).2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text.
