Embodiment 1

[0038] A safety management method for energy isolation, comprising the following steps:

[0039] Step 1: Before the maintenance of the equipment, the maintenance personnel shall handle the written power-off approval. After the approval is passed, the electrician shall carry out the power-off operation of the power supply and the control circuit, and confirm that the power supply drawer is pulled out or the switch is turned off, and the equipment is in the "stop" state. "Location.

[0040] Step 2: After the electrician confirms that the equipment has been powered off, hang a special warning sign on the power supply drawer or switch in the electrical room, and the special warning sign is marked with warning words such as "equipment maintenance, prohibit closing".

[0041] Step 3: The maintenance personnel and the electrician lock the pull-out drawer or the switch respectively, and the two locks have different lock cylinders, that is, the maintenance personnel hold the key Ⅰ, and...

Embodiment 2

[0048] Embodiment 2 is basically as attached image 3 with Figure 4 Shown:

[0049]The difference from Embodiment 1 is that the second connecting plate 4 is slidably connected to the horizontal bar 2, and the specific setting is: a chute 6 is opened along the length direction of the horizontal bar 2, and the second connecting plate 4 is slidably connected in the chute 6 , the end of the second connecting plate 4 and the chute 6 away from the first connecting plate 3 is fixed with a compression spring 7, initially the second connecting plate 4 is close to the first connecting plate 3, in addition, in order to improve stability, the first connecting plate 3 and the second connecting plate 4 are both magnetic plates, and the first connecting plate 3 and the second connecting plate 4 attract each other. This can be applied to the sides of power supply drawers of different thicknesses.

Abstract

The invention relates to the technical field of electrical equipment safety management, and particularly discloses a safety management method of energy isolation. The safety management method of energy isolation comprises the following steps that (1) a maintainer handles a written outage approval, and an electrician conducts outage operation of a power source and a control circuit; (2) after the electrician confirms that equipment is in a power outage, a special warning sign is hung on power supply drawers or switches of an electrical room; (3) the maintainer and the electrician lock the drawers which are pulled out or the switches; (4) a centralized lock box is arranged in a central control room, and keys are collected and managed in a unified mode; and (5) the maintainer and the electrician get the locks after going through the specific application procedures, the power supply drawers or the switches of the electrical room are unlocked, and energy isolation is cancelled. By the adoption of the safety management method of energy isolation, the keys which exist after locking is accomplished are placed in the centralized and unified storage lock box, the lock box is arranged in thecentral control room which conducts remote control, and therefore the phenomena that due to the fact that a remote operator, the electrician and the maintainer do not smoothly conduct information communication, the energy isolation of the equipment fails, and the casualty accident happens are avoided.

Description

technical field [0001] The invention relates to the technical field of electrical equipment safety management, in particular to an energy isolation safety management method. Background technique [0002] During the daily maintenance of electrical equipment, cement production enterprises need to cut off the power of the electrical equipment before proceeding. The current energy isolation process is that before the equipment is overhauled, the maintenance personnel will apply for a written power-off approval, and then the electrician will power off the power supply and the control circuit to confirm that the power supply drawer is pulled out or the switch is off, and the equipment is in the "stop" state. position, so that the equipment cannot be started, and the energy cannot be accidentally released. After the maintenance is completed, the electrician will close the power supply drawer or switch. However, due to poor information communication between the electrician and the m...
