Abstract
The utility model relates to a switch cabinet cable chamber blocking device. The switch cabinet cable chamber blocking device comprises a hinge which is composed of an upper hinge sheet, a lower hinge sheet and a pin. The switch cabinet cable chamber blocking device is characterized in that the upper hinge sheet and the lower hinge sheet are respectively an L-shaped structure, the upper hinge sheet and the lower hinge sheet form a square cylindrical hinge, a central position of a side face of the upper hinge sheet is provided with a bolt mounting hole with a diameter of 8cm, and central portions of a top face of the upper hinge sheet and a bottom face of the lower hinge sheet are coaxially provided with a program lock mounting hole of a built-in program chip with a diameter of 13cm. When the switch cabinet cable chamber blocking device is used, the lower hinge sheet is opened, a fastening bolt penetrates through a bolt hole at the side face of the upper hinge sheet to enter a fastening thread hole of a cable chamber compartment door, the lower hinge sheet is closed, a program lock which can be opened only through a computer key having an unlocking command in a transformer station is mounted in the program lock mounting hole, the upper hinge sheet and the lower hinge sheet are mutually locked through the program lock, and thereby the error-locking prevention function of the switch cabinet cable chamber is realized.
Description
Technical field
The present invention relates to electric power system middle-high voltage switch, specifically a kind of easy to operate, use safe switch cubicle cable vault locking device.
Background technology
Anti-misoperation locking device is the visual plant that transformer station prevents " five large types " misoperation, and misoperation-proof locking device is the important leverage of the person, electrical network and device security stable operation reliably." 18 great anti-accident measures of electrical network of State Grid Corporation of China " are pointed out: high-tension switch cabinet should be selected the product of " five is anti-" complete function." State Grid Corporation of China's electric power safety working regulation " also clearly specifies: high voltage electric equipment all should be installed perfect misoperation-proof locking device.And have perfect anti-misoperation locking device function, what do not have anti mis-closedown function should install mechanical lock additional.
At present, ZS1 type switch cubicle is the 10kV switch cubicle product of ABB AB's development and production, its cable vault's door is by fastened by screw, no matter banded cable is not charged, with special-purpose cranking bar even screwdriver door can be opened, do not possess anti-incorrect manipulation deadlock function, violate above-mentioned code requirement, very easily cause personnel's electric shock accidents.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of working specification is provided, uses safe switch cubicle cable vault locking device.
The present invention can reach by following measure:
A kind of switch cubicle cable vault locking device, comprise the hinge being formed by upper leaf of hinge, lower jaw sheet and bearing pin, it is characterized in that leaf of hinge and lower jaw sheet are all L-shaped, upper leaf of hinge and lower jaw sheet composition square tube shape hinge, the bolt mounting holes that the central part diameter of the side of upper leaf of hinge is 8cm, the central part of the bottom surface of the end face of upper leaf of hinge and lower jaw sheet is provided with the procedure lock installing hole that coaxial line diameter is the plug-in chip of 13cm.
The back side and the bolt hole wall of upper hinge described in the utility model side are provided with insulating barrier, charged to prevent upper leaf of hinge and lower jaw sheet.
When the utility model uses, open lower jaw sheet, fastening bolt is entered to the fastening screw pit of cable vault's door through the bolt hole of upper leaf of hinge side, close and close lower jaw sheet, openable the computer key side of only holding unlock command in transformer station procedure lock is arranged in procedure lock installing hole, procedure lock locks together upper leaf of hinge and lower jaw sheet, and then reaches the anti mis-closedown function of switch cubicle cable vault.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
A kind of switch cubicle cable vault locking device, comprise by upper leaf of hinge 1, the hinge that lower jaw sheet 2 and bearing pin 3 form, upper leaf of hinge 1 and lower jaw sheet 2 are all L-shaped, upper leaf of hinge 1 and lower jaw sheet 2 form square tube shape hinge, the bolt mounting holes that the central part diameter of the side of upper leaf of hinge 1 is 8cm, the back side and the bolt hole wall of upper hinge 1 side are provided with insulating barrier, charged to prevent upper leaf of hinge and lower jaw sheet, the central part of the bottom surface of the end face of upper leaf of hinge 1 and lower jaw sheet 2 is provided with the procedure lock installing hole that coaxial line diameter is the plug-in chip of 13cm, mechanical strength and the mechanical endurance of upper leaf of hinge 1 and lower jaw sheet 2 all meet the demands, and dimensional structure can effectively splice with the holding screw of cable vault's door of ZS1 type switch cubicle, the procedure lock of plug-in chip is after built-in switch cabinet grounding switch closes, the order that cable vault's door could be opened, when the utility model uses, open lower jaw sheet, fastening bolt is entered to the fastening screw pit of cable vault's door through the bolt hole of upper leaf of hinge side, close and close lower jaw sheet, openable the computer key side of only holding unlock command in transformer station procedure lock is arranged in procedure lock installing hole, procedure lock locks together upper leaf of hinge and lower jaw sheet, and then reach the anti mis-closedown function of switch cubicle cable vault, tool has the following advantages: (1) possesses perfect " five is anti-" requirement, (2) cost is low, economic benefit is high, (3) can realize not having a power failure and install additional, and can not cause interference, impact to operational outfit in installation process, (4) hinge adopts high-strength alloy steel making, should not damage, and compact overall structure, volume are small and exquisite, install additional efficient and convenient.
Claims (2)
1. a switch cubicle cable vault locking device, comprise the hinge being formed by upper leaf of hinge, lower jaw sheet and bearing pin, it is characterized in that leaf of hinge and lower jaw sheet are all L-shaped, upper leaf of hinge and lower jaw sheet composition square tube shape hinge, the bolt mounting holes that the central part diameter of the side of upper leaf of hinge is 8cm, the central part of the bottom surface of the end face of upper leaf of hinge and lower jaw sheet is provided with the procedure lock installing hole that coaxial line diameter is the plug-in chip of 13cm.
