Description

technical field [0001] The invention relates to a portable substation inspection key bag. Background technique [0002] There are a large number of substation daily inspection keys, which brings a lot of convenience to the management and use of the staff. Many keys are put together in the process of use, and it usually takes more than one minute to select the required key from dozens of keys, and sometimes it takes three to five minutes, and it takes only one minute to unlock the key after selecting it. It takes a few seconds to select the key, which consumes a lot of energy and time of the staff, directly affects the work efficiency of the patrol staff, and increases the labor intensity; in addition, the staff cannot put the key back to the original position after the key is used After three uses, the key is placed in a disorderly manner, which increases the difficulty of selecting the key, prolongs the time of selection, and increases the probability of misusing the key....

AI Technical Summary

Problems solved by technology

Many keys are put together in the process of use, and it usually takes more than one minute to select the required key from dozens of keys, and sometimes it takes three to five minutes, and it takes only one minute to unlock the key after selecting it. It takes a few seconds to select the key, which consumes a lot of energy and time of the staff, directly affects the work efficiency of the patrol staff, and increases the labor intensity; in addition, the staff cannot put the key back to the original position after the key is used After three uses, the keys are placed in a disorderly manner, which increases the difficulty of selecting keys, prolongs the selection time, and increases the probability of misuse of keys

Moreover, since many keys are placed together, some of them are lost during use and are difficult to find in time, and cannot be found or replenished in time. Therefore, when it is necessary to open the substation equipment urgently, the key cannot be found. Bring extremely serious adverse consequences and bring unnecessary heavy losses to the substation
