Operating handle knife combination tool developed applications

        Substation switching operation is one of the main staff of daily work, which require appropriate operating rod handle and manual operation knife and the knife to make aid. Since the knife operating mechanism type, number range, the required operating handle and shake the handle correspondingly more extensive set-only, display confusion, likely to cause loss situation; moreover, the operation is prone to leakage choose to take, take the wrong circumstances, wasting time, influence switching operation efficiency.
        1 Situation Analysis
        Substation grid point station, high and low voltage switching hub, is an important part of the whole grid, are responsible for the security and stability and to ensure the reliability of power supply to the user important responsibilities. As substation operation personnel switching operation can be said that the most important task of daily switching operation according to the requirements of "ready operatives appliance" link states: prepare the operating handle, short films, error prevention means ordinary key operations such as tools, ready insulated gloves, insulated boots, electroscope, grounding wire and other safety equipment (as required inspection test date, without damage, examine the electrical pen high voltage generator, intact ground wire, etc.) which required manual operation handle and shake the handle bars into operation, including:. 220kv to operate the knife handle, 110kv ground knife and knife handle and the operating rod, 35kv and knife to knife operating bar and handle, according to different voltage levels and types of equipment, the operating handle should be prepared also different.
        According to statistics, during a switching operation in accordance with the number of different operating steps, time switching operation generally ranging from 1h 2min to Accept positive start operation after the operator to make the appliance ready link, generally takes about 2min, if halfway operation of industrial equipment does not appear to match or omission return to replace industrial equipment room, it is generally time-consuming again 5min to 10min range, depending on the site where the distance from the safety equipment room may be not only a waste of operating time, reducing operating efficiency, and to interrupt the operation is a hotbed of potential accidents, production safety hazards and caused the loss will be immeasurable addition, according to the State grid Corporation news: July 2, 2008 xx changed occurred because no serious reconciliation device name, the wrong interval, closing earthing knife caused by misuse bus differential motion a vicious accident.
        A major reason for the accident: operating tools ready omissions, resulting operation is interrupted, the return operation wrong interval summary, the current operating handle knife substation used not only put confusion, easy to lose, the more important. when selecting an operating error-prone, process switching operation is unnecessary trouble, affecting the switching operation efficiency, and may even threaten corporate security production targets.
        In order to avoid the operation due to the knife caused by improper operation handle select interruption switching operation to improve efficiency, enhance operational safety level; and to achieve the operating handle knife standardization and fine management, to avoid the guillotine operating handle is missing, improve management efficiency, I set - to enhance the level of operation and maintenance station Mo Rong proposed improvement scheme - making knife operation handle toolbox.
        2 improvement program
        In life, we often see a lot of tools and assembly kit toolbox, such as a screwdriver kit, auto repair tool set with a lorry, electrician toolbox kits, etc. These combination tool not only to carry, easy to use and neatly kept, with the It was taken, access to less error-prone. Therefore, we consider the guillotine operation tool used by the station, too, can be given by a toolbox set, in order to achieve our goal of ease of use and storage specifications.
        2.1 Main analysis can clearly be seen:
        ① personnel to handle what the knife does not apply to master, easy left at the scene after the operation, after arbitrarily placed, due to personal habits of these different reasons, it is difficult to control, not the main reason;
        ② interval range equipment, unified improve a huge project, so it is not the main reason;
        ③ knife handle the interface is not uniform, varying lengths, leading to handle variety, is the main reason;
        ④ select from memory the operating handle, when placed by eye, leading to confusion placed, and easy access to omissions, errors, is the main reason;
        ⑤ safety equipment cabinet set-extensive display space provided does not match with the handle, causing confusion placed, not standardized, it is the main reason.
        2.2 determine improvement program
        2.2.1 Strategies
        (1) Statistics interface type knife handle, the blade segment operating handle truncated unified manual operation section, the joint portion of the knife statistics standard truncated, making the connection port for connecting the handle and the joint, so that we can achieve operating handle knife standardization, refinement requirements;
        (2) the preparation of the knife handle selected correspondence table, each interval knife operation needed to fill in the operating handle part code correspondence table, select the needed operation, so they can avoid the knife caused by improper operation handle select operation interruption;
        (3) making the operating handle kit, the operating handle components in a unified set-box, each box parts category, sub-regional set-in a fixed position, so that we can avoid the knife handle operating loss, improve management efficiency, enhance the level set - .
        OK 2.2.2 truncated segment and the connection head
        Since the voltage levels and different models of different blade operating rod length and interfaces needed, so I decided to sub-section operation bar truncated to a unified operating handle portion, an intermediate connecting portion and special operations joint portion of the rod, each part threaded connection, operation as required for the desired joint to the operating handle, the intermediate connecting rod is mainly used 220kv guillotine operation to lengthen the operating rod. threaded connection should ensure that qualified torque, the torque required to meet the operational requirements. the operating handle truncated , the required header into the shake rocker, special joint operation, which is equipped with rocker unified and uniform connection member, joint special operations connected with the rocker portion unity, rocker and joint use of a snap connection, operation rod operation. snap connection should ensure torque qualified to meet the operational requirements of the desired torque.
        Space and produced by the various components of the operating handle knife combination TOOLBOX 2.2.3 according to standardized intelligence provided safety equipment cabinet, produced a knife operation handle combination toolbox, each member will be lined with foam separator distinction provided part code regulate their tank display, select the corresponding table knife operation handle is placed in a prominent location inside the whole set into safety equipment cabinet.
        3 embodiment and its application prospect
        Through this operation the practical application of the knife handle toolbox, a change in the original operating rod placed the phenomenon of chaos, not only to avoid the operation due to the knife caused by improper operation handle select interruption, the switching operation to improve efficiency, enhance operational safety level and to achieve the knife handle standardized operation, fine management, to avoid the guillotine operating handle is missing, improve management efficiency, enhance the level of set-present toolbox although by the existing operating rod and handle statistics produced but inside the space surplus, if special knife operating mechanism beyond the scope of existing statistical appears, simply make joint special operation, the default setting in the toolbox to meet the requirements.
        4 Conclusion
        Operating handle knife combination tool, is an improvement over the existing operating tool knife, and improve the use of existing operating rod handle and store the weak point, operation and maintenance personnel to solve the substation switching operation of the practical problems.
