Description
Technical field
The present invention relates to a kind of 10 kilovolts of proportioning device of high voltage electric energy accidental opening preventative lockings, for 10 kilovolts of electric power complete set of equipments.
Background technology
The on-the-spot installation of 10 kilovolts of high-voltage electric-energy meters, maintenance, maintenance work, there is the small-sized dispersion of operation field, multi-point and wide-ranging, the concrete single work on the spot time is shorter, be responsible for operate high pressure equipment and implemented the characteristics such as safety measure by electricity consumption client electrician personnel, there are some potential safety hazards in work on the spot.Under running status, the general level of the health of subscriber equipment varies, managerial attention degree and electrician personnel's quality is uneven, cause " two tickets " system in safety management to be difficult to real implementing the user, cause the organiztion measure that guarantees the electric energy metrical field work safe to be difficult to implement fully; In work, find, 10 kilovolts of incomplete situations of high-tension apparatus ubiquity safety protection facility of electricity consumption client, many high pressure clients' incoming line cabinet only adopts artificial padlock protection method, due to long neglected and in disrepair, the reason of mismanagement, lockset is incomplete or hard-to-use situation is a lot, if the staff lacks again enough awareness of safety, do not fulfil necessary safety measure, just easy mistakenly entering charged chamber, cause human casualty accident.According to statistics, in the security incident of nearly 2 years State Grid Corporation of China, the shared ratio of the personal electric shock casualty accident of electric energy metrical and high pressure client power utility check specialty is very high, and presents ascendant trend.
Anti-misoperation locking device with " five anti-" function be guarantee the person and device security, prevent misoperation, false touch misses the important technique measure of touching charging equipment, at present, the links of electrical production has extensively adopted the anti-misoperation locking device with " five is anti-" function, take technological means as main, stop the people and touch for misoperation, mistake the Developing mainstream that charging equipment has also become the electric power safety management.And, in the electric power meter part, do not have anti-misoperation locking device between high-voltage metering cubicle and inlet wire on-load switch, and causing generation personnel mistakenly entering charged chamber, mistake is touched, the probability of false touch charging equipment increases, and personal electric shock casualty accident very easily occurs.
Summary of the invention
The object of the present invention is to provide a kind of 10 kilovolts of proportioning device of high voltage electric energy accidental opening preventative lockings, it has the mechanical interlocking function, has realized the anti-error dual fail-safe of the high-voltage meter person, effectively avoids personal electric shock casualty accident.
Technical scheme of the present invention is achieved in that a kind of 10 kilovolts of proportioning device of high voltage electric energy accidental opening preventative lockings, by metering cabinet with become by electric group, it is characterized in that: at the metering cabinet door and be subject to, between electric cabinet isolating switch, blocking mechanism is installed, blocking mechanism is comprised of jam plate, locking bar, fixed hub, connecting lever, connecting rod, drive link, pressing plate, rolling disc and operating handle; Wherein jam plate is fixed on metering cabinet cabinet door, locking bar one end coordinates with jam plate, the locking bar other end and connecting lever one end active link, the center of connecting lever is connected with fixed hub, and fixed hub is connected with being subject to electric cabinet, and the connecting lever other end is connected and moves up and down with connecting rod, connecting rod is connected with pressing plate by drive link, pressing plate top is 30 degree angles, but update handle on rolling disc, and rolling disc coordinates with pressing plate top.
Good effect of the present invention is; Guarantee the field operation personal safety, realize the target of electric energy metrical work on the spot essential safety, effectively avoid personal electric shock casualty accident.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is plan structure figure of the present invention.
Fig. 3 is embodiments of the invention figure.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described: as shown in Figure 1, 2, 3, a kind of 10 kilovolts of proportioning device of high voltage electric energy accidental opening preventative lockings, by metering cabinet with become by electric group, it is characterized in that: at the metering cabinet door and be subject to, between electric cabinet isolating switch, blocking mechanism is installed, blocking mechanism is comprised of jam plate 1, locking bar 2, fixed hub 3, connecting lever 4, connecting rod 5, drive link 6, pressing plate 7, rolling disc 8 and operating handle 9; Wherein jam plate 1 is fixed on metering cabinet door 10, locking bar 2 one ends coordinate with jam plate 1, locking bar 2 other ends and connecting lever 4 one end active links, the center of connecting lever 4 is connected with fixed hub 3, and fixed hub 3 is connected with being subject to electric cabinet 11, and connecting lever 4 other ends are connected and move up and down with connecting rod 5, connecting rod 5 is connected with pressing plate 7 by drive link 6, pressing plate 7 tops are 30 degree angles, but update handle 9 on rolling disc 8, and rolling disc 8 coordinates with pressing plate 7 tops.
When being subject to electric cabinet isolating switch in closure state (now metering cabinet is charged interval), operating handle 9 is depressed, and pins metering cabinet door 10, and metering cabinet door 10 can't be opened, and prevents operating personnel's mistakenly entering charged chamber; When being subject to electric cabinet 11 isolating switches in separated position, metering cabinet door 10 can be opened.
While opening metering cabinet door 10 in work, connecting rod 5 moves upward and drives connecting lever 4 and moved centered by fixed hub 3 under the control of operating handle 9, locking bar 2 under the drive of connecting lever 4 to left movement, this hour locking lever 2 breaks away from jam plate 1, metering cabinet door 10 can be opened, and while closing as long as operating handle 9 can make connecting rod 5 move downward, drive locking bar 2 to move right in rear insertion jam plate 1, make 10 lockings of metering cabinet door.
