The invention provides an intelligent protection locking system used for controlling accidental release of electric energy. The system comprises an intelligent locking device and an intelligent bracelet, wherein the intelligent locking device covers an electric operating equipment switch, so that accidental switching on by other operators is effectively prevented; and the intelligent bracelet is worn on a wrist of a maintainer, and is used for receiving various instructions transmitted by the intelligent locking device. Through cooperative work between the intelligent bracelet worn on the wrist of the maintainer and the intelligent locking device locked to the electric operating equipment switch, the system has an accidental unlocking alarming function, a locking overtime prompting function and other functions; particularly, energy isolation is implemented through intelligent means, and then accidental release of dangerous energy is effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment safety protection, and in particular relates to a protection locking system for controlling accidental release of electric energy. Background technique [0002] During the operation of the equipment in the production site of petrochemical enterprises, especially when the staff is performing work tasks such as inspection and maintenance, the staff is always facing the danger of injury caused by the accidental release of energy, which may cause dangerous energy to the staff including, but Not limited to the following types: electrical energy, mechanical shock, hazardous chemicals, explosion shock, etc. And such a risk is often due to the accidental release of energy due to misoperation by the staff, which in turn leads to safety accidents. [0003] In petrochemical enterprises, when inspecting and maintaining various equipment, because of the electrical energy and mechanical energy tha...
