PROTEÇÕES PARA MÁQUINAS E EQUIPAMENTOS

Abstract

The present study has as its theme “Protections for machines and equipment”, with Emphasis on research on electrical protection for machinery and equipment. So the present The aim of this study was to review the literature on the protection requirements for machines and electrical protections. It also aimed to: discuss the regulatory norms, especially the NR12 at work safety; discuss the types of protection on machines and equipments; name the protective electrical devices; talk about the electrical circuits of security. The study is justified and relevant because, despite the undeniable importance of NR12, it is known that the vast majority of Brazilian companies this standard is not observed in full and often not even partially according to recent research This is due to the lack of trained, qualified and qualified professionals in the job market. It has been seen that a security system aims to prevent direct contact operators with moving and dangerous parts of the machines. For these systems devices that prevent their automatic operation are necessary when work failures occur. Thus, it can be concluded that with the various models of instruments and correct installation of them a safe method one can come up with a secure solution in accordance with NR12. Thus it was realized that the functionality of a system safety depends on the correct installation of the safety electrical devices in the machines.
