Description
Technical field
The utility model 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, by electricity consumption client electrician personnel, being responsible for operate high pressure equipment and being implemented the features such as safety measure, 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 user, cause the organiztion measure that guarantees electric energy metrical field work safe to be difficult to implement completely; 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 staff lacks again enough awareness of safety, do not fulfil necessary safety measure, just easy mistakenly entering charged chamber, causes human casualty accident.According to statistics in the security incident of ，Jin Liangnian State Grid Corporation of China, the shared ratio of electric energy metrical and the personal electric shock casualty accident of high pressure client power utility check specialty is very high, and presents ascendant trend.
The anti-misoperation locking device with " five anti-" function is to guarantee the person and device security, prevent that misoperation, false touch from touching the important technique measure of charging equipment by mistake, 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 people for misoperation, touch the Developing mainstream that charging equipment has also become electric power safety management by mistake.And in electric power meter part, anti-misoperation locking device not between high-voltage metering cubicle and inlet wire on-load switch, causes generation personnel mistakenly entering charged chamber, touch, the probability of false touch charging equipment increases, and personal electric shock casualty accident very easily occurs by mistake.
Summary of the invention
The purpose of this utility model is to provide a kind of 10 kilovolts of proportioning device of high voltage electric energy accidental opening preventative lockings, and it has mechanical interlocking function, has realized the anti-error dual fail-safe of the high-voltage meter person, effectively avoids personal electric shock casualty accident.
The technical solution of the utility model 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 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, can update handle on rolling disc, and rolling disc coordinates with pressing plate top.
Good effect of the present utility model is; Guarantee field operation personal safety, realize the target of electric energy metrical work on the spot essential safety, effectively avoid personal electric shock casualty accident.

Fig. 3 is enforcement illustration of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is 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 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 end 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, can update handles 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 cannot 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 to move 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 departs 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.
