Energy isolation system of oil field united station and energy isolation method

Abstract

An energy isolation system of an oil field united station comprises an energy isolation device and a to-be-isolated electromechanical device, wherein a first locking device is arranged on the energy isolation device and can move between a locking position and an unlocking position, and the energy isolation device blocks or isolates energy released by the to-be-isolated electromechanical device when the first locking device is located in the locking position; at least one second locking device is also arranged on the energy isolation device and can keep the first locking device in the locking position. The at least one independent second locking device is additionally arranged outside the energy isolation device and limits the unlocking moving method of the first locking device to prevent the first locking device from moving into the unlocking position, the risk of accidental release of energy caused by misoperation can be effectively prevented, and the accidental release of hazardous energy can be effectively controlled.

Description

technical field [0001] The invention relates to the field of safety equipment for electromechanical devices in production sites in the petroleum field, in particular to an energy isolation system and an energy isolation method for an oil field joint station. Background technique [0002] During the operation of the equipment in the production site in the petroleum field, the staff are always facing the danger of injury caused by the accidental release of energy. The energy that may cause danger to the staff includes, but is not limited to the following: electrical energy, mechanical Shock, chemical toxic and harmful substances, explosion shock, etc. [0003] For example, a typical oil field joint station includes buildings, oil storage tanks, sewage tanks, clean water tanks, pump rooms, power distribution rooms, process pipe networks and other devices. When the staff of the oil field joint station perform maintenance and other tasks, There are risks of accidents caused by t...

Problems solved by technology

[0003] For example, a typical oil field joint station includes buildings, oil storage tanks, sewage tanks, clean water tanks, pump rooms, power distribution rooms, process pipe networks and other devices. When the staff of the oil field joint station perform maintenance and other tasks, There are risks of accidents caused by the release of energy such as electricity, mechanical shock, chemical poisoning, and explosive liquids, and such risks are usually due to the accidental release of energy due to the misoperation of the staff, which in turn leads to safety accidents

[0004] In the prior art, there is no systematic and effective solution for accidents caused by the accidental release of energy in a typical oilfield combined station. The usual solution is usually as disclosed on pages 106-107 of the journal "Modern Occupational Safety" in the 8th issue of 2010 , The staff simply locks and tags out the energy isolation, but
