Main dangerous points and real-time control in the process of switching operation

in China,

electrical misoperation accidents are extremely harmful, and the main reason for misoperation accidents is that the dangerous points in the process of switching operation are not effectively controlled. Therefore, find out the dangerous points in the process of switching operation, analyze their causes, and 2 When the wet experiment is tested, the experiment can be controlled in real time when it is carried out at room temperature, which is of great significance to prevent electrical misoperation accidents

1 main danger points in the switching operation process

danger points in the switching operation process refer to the behaviors that may cause accidents during the switching operation of electrical operators, which are the inducing causes of accidents

the dangerous points in the switching operation mainly include the following points:

(1) the equipment name, number and position are not carefully checked before operation

(2) single person operation or no ticket operation

(3) do not carefully check the switch position before pulling and closing the knife switch

(4) do not check the power before installing the grounding wire (closing the grounding knife switch)

(5) before power transmission, do not carefully check whether all safety measures within the power transmission range are removed

2 switching operation has lost the product image and the formation reasons of dangerous points in the process of shopping malls.

switching operation system is an effective measure to ensure the smooth progress of switching operation. However, due to various reasons, the switching operation system is often not really implemented in actual operation, resulting in the formation of various dangerous points in the process of switching operation, The main reasons are:

2.1 carelessness, blind self-confidence, ideological neglect

some operators think they are familiar with the equipment, blind self-confidence, carelessness, do not carefully check the equipment number, look at it casually, and even operate by feeling; For some simple operations, such as the shutdown and power transmission of a single interval, the operation is considered to be simple, easy and error free, so it is operated by one person or without ticket. Facts have proved that the vast majority of misoperation accidents are caused by simple operation

2.2 rush for time and speed

in case of many operation tasks or shift handover, rush for time and speed in order to complete the operation as soon as possible, or do not carefully check and check the equipment, and do not operate in a hurry according to the specifications, or the supervisor himself also operates, so that the operator loses his supervision and forms a single person operation

2.3 usually do not develop good working habits

some operators usually do not strictly require themselves, work carelessly and carelessly, do not strictly follow the procedures and requirements specified in the regulations in their work, do not carefully check those who should check, do not carefully check those who should check, and some even know that they are in violation of the rules, but still get lucky and act recklessly, and over time, develop bad working habits

2.4 the lessons of previous accidents are not carefully learned

it can be seen from the accidents that many accidents are very similar in nature, which is enough to show that the operator has not seriously learned the lessons of previous accidents at all. For the accidents occurred by others, some operators are indifferent. Learning the accident notification is like listening to a story, and do not seriously summarize the experience and lessons

3 control of dangerous points in the process of switching operation

to avoid misoperation accidents, the key is to strictly implement the two ticket three system and control the dangerous points in the process of switching operation in real time. In view of the main dangerous points and causes in the process of switching operation, operators should be educated to develop good working habits at ordinary times. For every operation, even the simplest one should be attached great importance to ideologically, overcome carelessness and fluke, and operate in strict accordance with the specified procedures. We should learn from the accident lessons of others and constantly correct our own bad behaviors in the process of switching operation

peel strength testing machine

corresponds to the dangerous points listed above. Specific to the process of each switching operation, it can be prevented and controlled from the following aspects:

(1) the name, number and location of the equipment must be carefully checked before switching operation

(2) any operation must be carried out by 2 people, and single person operation is strictly prohibited

(3) confirm that the switch is in the off position before pulling and closing the knife switch

(4) check the electricity before installing the grounding wire (grounding knife)

(5) before power transmission, it must be checked that all grounding wires within the power transmission range have been removed and all grounding knife switches have been opened

if the operating personnel carefully do the above points during each switching operation, then it is completely avoidable to pull and close the switch with load, hang the grounding wire (grounding knife), close the switch with grounding wire (grounding knife), stop and send power by mistake, and misoperation caused by entering the live interval by mistake
