摘要

残余电流装置(rcd)是低压装置中最常用的装置，用于防止触电和火灾。在触电风险高的情况下，rcd的应用是强制性的。目前，局部直流微电网的推广受到了广泛的关注。这给保护系统，特别是基于rcd的保护系统带来了新的挑战。本研究的主要目的是通过模拟直流微电网中可能发生的情况，测试b型rcd的运行情况，并评估使用这种rcd的电气安全有效性。研究表明，理论上相同的rcd在技术数据方面可能具有不同的脱扣特性，包括对残余直流电没有反应，这有触电的风险。这表明有必要扩大制造商进行的规范性测试。从直流微电网中人员安全的角度出发，说明了这些附加rcd测试的范围。

Electrical safety in low-voltage DC microgrids with B-type residual current devices

Residual current devices (RCDs) are most popular devices used in low-voltage installations for protection against electric shock and fire. In cases of high risk of electric shock the application of RCDs is mandatory. Currently, the spread of local direct current (DC) microgrids is widely considered. This creates new challenges for protective systems, in particular those based on RCDs. The main purpose of the research is to test the operation of B-type RCDs by simulating the conditions that may occur in DC microgrids as well as assessment of the effectiveness of electrical safety with the use of such RCDs. The research has revealed that theoretically identical RCDs in terms of technical data can have different tripping properties, including no reaction to residual direct current, which poses a risk of electric shock. This signalizes the necessity of extension of the normative tests performed by manufacturers. The scope of these additional RCDs tests is indicated, from the point of view of the persons’ safety in DC microgrids.

期刊介绍： The quarterly Eksploatacja i Niezawodność – Maintenance and Reliability publishes articles containing original results of experimental research on the durabilty and reliability of technical objects. We also accept papers presenting theoretical analyses supported by physical interpretation of causes or ones that have been verified empirically. Eksploatacja i Niezawodność – Maintenance and Reliability also publishes articles on innovative modeling approaches and research methods regarding the durability and reliability of objects.
