Abstract
The invention discloses an operation method of an L-shaped locking device of isolation baffles of a handcart type switch cabinet. The L-shaped locking device comprises two L-shaped fixed plates with the same size and the same shape, and two ends of each fixed plate are both provided with penetration holes which are respectively a mounting hole and a lock hole; and the two fixed plates are respectively and fixedly arranged on two isolation baffles of the switch cabinet, and the lock holes of the two fixed plates are corresponding to each other and are locked by program locks. The mounting operation method of the L-shaped locking device comprises the following steps: A, two nuts are respectively embedded on the two isolation baffles of the switch cabinet, and the positions of the nuts on the two isolation baffles are symmetric; B, the two mounting holes in the fixed plates are aligned to the two embedded nuts on the isolation baffles and are fixed by screws; and C, lock bars of the program locks penetrate into the lock holes of the two fixed plates to be locked, so that the lock cabinet is locked.
Description
Technical field:
The present invention relates to the L shaped locking device operational method of handcart switch cabinet partitions; Relate in particular to the locking device operational method of handcart switch cabinet partitions; Be that reliable locking partitions prevented personnel's mistakenly entering into charged position when handcart space parts overhauled in cabinet.
Background technology:
Operating 10～35kV handcart switch cabinet (containing mid-cabinet); When parts such as the travel switch in handcart space, kinematic link, transducer, dehumidifier need overhaul in the cabinet; Requirement is reliably sealed partitions; Opens partitions and touch charged position to prevent that personnel from opening by mistake, and present situation is also pessimistic, shows as:
1, security regulations are arranged and the device that puts rules into practice is not comprehensive: several human casualty accident cases relate to " electric power safety working regulation " 4.5.4 regulation in recent years: " after wheelbarrow switch is pulled out in the high-tension switch cabinet; forbid opening after isolating the baffle plate sealing at charged position; and be provided with ' halt, Keep Clear-High Voltage! ' indication plate ", regulation has played guidance, educated and has forbidden effect, but the concrete device of for want of implementing, carrying out, indication plate fails effectively to stop act of violating regulations.
2, the handcart-type switch cabinet static contact is anti-error goes into function and has leak: find through on-site inspection and data consultation; Existing production and operating switch cubicle installed the partitions that can cover charged fixed contact, but do not have the design and installation locking device; After the switch handcart is pulled out; Isolate the plate washer interlinked mechanism and be directly exposed in the cabinet space, a people just can at will open, and this device defect at home and abroad all exists in the product.
3, the anti-measure that is strayed in maintenance scene relies on employee's consciousness and artificial monitoring fully: the anti-measure of taking at present of being strayed into is after the wheelbarrow switch of commentaries on classics inspecting state is pulled out, to pin door of switch cabinet.The anti-problem that is strayed into when this measure has solved " wheelbarrow switch maintenance "; But when parts such as the travel switch in the handcart storehouse, kinematic link, transducer, dehumidifier need overhaul, the cabinet door of locking must be opened, and the anti-measure that is strayed into is compelled to remove; Can only be provided with " halt, Keep Clear-High Voltage! " indication plate, and the monitoring that tightens security, emphasis safety is told somebody what one's real intentions are, and specifies the specific responsibility guardian in case of necessity, in case guardian and maintenance people are careless and inadvertent, danger just possibly take place.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide the L shaped locking device operational method of a kind of handcart switch cabinet partitions; The effect of this device is: when handcart space parts overhauled in cabinet, locking partitions reliably prevented personnel's mistakenly entering into charged position.
Technical solution problem of the present invention adopts following technical scheme:
The L shaped locking device operational method of handcart switch cabinet partitions, said L shaped locking device comprises: two block sizes, L shaped stator that shape is identical are set, and the two ends of each stator all offer perforation, are respectively installing hole and lockhole; Said two stators are fixedly set in respectively on two partitions of said switch cubicle, and the lockhole of two stators is corresponding also through the procedure lock locking; Said two stators adopt stainless steel or deposited zine plate to process, and the corners circle of position slips over and crosses; The installation exercise method of said L shaped locking device is carried out as follows:
A, to the switch cubicle transformation, embedded nut respectively on two partitions of switch cubicle, pre-buried two nuts on the every partitions, the nut location on two partitions should symmetry;
B, a L shaped stator is installed on each piece partitions, two installing holes on the stator are aligned on two embedded nuts on the partitions, stator is fixed on the partitions with screw;
After C, two stators are fixedly mounted on two partitions respectively, the locking bar of procedure lock are penetrated in the lockhole of two stators, to pin to realize the switch cubicle locking.
Compared with present technology, beneficial effect of the present invention is embodied in:
Effect one:
Before the enforcement, the anti-device that is strayed into of handcart type high-voltage switch cabinet is not comprehensive, and carry out safety and rely on manual work fully, and the accident happens case.After the enforcement, remedied the anti-design defect that is strayed into of switch cubicle, the regulation of carrying out " after wheelbarrow switch is pulled out in the high-tension switch cabinet, isolate the baffle plate sealing at charged position then forbid opening " has had device capable of using.
Effect two:
When parts such as the travel switch in the cabinet space, kinematic link, transducer, dehumidifier need overhaul: before the enforcement, interlinked mechanism directly exposed, and the contact partitions can at will be opened, and has personal Danger Electric shock risk.After the enforcement, the fixed contact partitions is reliably sealed, and has effectively isolated charged position, passivation simultaneously the wedge angle and the bead of stator, for personal safety has increased protecting wall.
Effect three:
1, the locking device that adopts stator to be combined into, the upper lock position of a reprogramming lock, thereby do not change operating process, do not have extra increase operation and maintainer's workload.
2, the stator simple structure is with low cost, and is easy for installation, installation site, two places, and different connected modes can supply the optional use of handcart switch cabinet (containing mid-cabinet) user or manufacturer.
3, when parts such as travel switch overhaul, the present invention can reliably seal partitions, opens partitions and touches charged position to prevent that personnel from opening by mistake; Remedied the anti-design defect that is strayed into function of switch cubicle; Do not change the operation flow process, do not influence handcart turnover and equipment safety operation smoothly, security regulations have had the device of carrying out; It is anti-violating the regulations movable to help, for personal safety has increased protecting wall.
The effect of table 2 embodiment of the present invention
Description of drawings:
Fig. 1 is the front view of two stators of the present invention; Fig. 2 is the left view of Fig. 1; Fig. 3 is user mode figure of the present invention (locking with procedure lock when being installed on the partitions of switch cubicle).
