Abstract
The invention discloses a switch cabinet front door fastening device. The device is suitable for an indoor alternating current switch cabinet of a power system and belongs to the technical field of electric appliances, wherein the rated voltage of the indoor alternating current switch cabinet is 3.6 to 12kV. The technical improvement of the device provided by the invention lies in that a lock hook system which is positioned by a guide column is arranged in a front door; and a lock groove which is corresponding to the lock hook is arranged on a door frame of the cabinet body. According to the switch cabinet front door fastening device, four sides of the front door can be fastened; when an arcing fault occurs, the device has the advantages of uniform stress and difficult deformation; the spilling of arc light and splashings can be effectively prevented; and the safety of personnel and equipment can be ensured.
Description
Technical field
The invention discloses a kind of front door of switch cabinet and tightly plug with molten metal device, it is applicable to the indoor AC switch cubicle of electric power system rated voltage 3.6-12kV, belongs to technical field of electric appliances.
Background technology
At present, China's electric power system rated voltage is the switch cubicle of 3.6-12kV, the confinement mode of its many employings left and right sides, cabinet Qianmen, when arcing fault occurs, cabinet Qianmen is under pressure and impacts very easily deformation, the effusion of arc light, high-temperature gas and splashings, often causes the direct injury of equipment and operating personnel.
Summary of the invention
The object of the invention is to solve the deficiency existed in above-mentioned technology, a kind of Qianmen device that four sides is tightly pluged with molten metal is provided.
In technical solution of the present invention, the inside at Qianmen is provided with the latch hook system of being located by guide pillar, and cabinet doorframe is provided with the longitudinal locked groove corresponding with latch hook and horizontal locked groove.
Wherein, described latch hook system, by door lock, gear, gear bar, longitudinal jam plate, horizontal jam plate, arc connecting plate, latch hook are formed, longitudinal jam plate and horizontal jam plate are equipped with latch hook, gear bar is equipped with at the middle part of longitudinal jam plate, and two horizontal jam plates are connected with longitudinal jam plate by two arc connecting plates respectively, and the mandrel that gear is fixed on door lock engages with gear bar.
When rotating clockwise door lock handle, gear drive gear bar behind closedown Qianmen, drive longitudinal jam plate lengthwise movement, horizontal jam plate transverse movement, latch hook correspondence enters longitudinal locked groove on cabinet doorframe and horizontal locked groove, and Qianmen is blocked, rotate counterclockwise door lock handle, Qianmen is unlocked.
Adopt the present invention, when arcing fault occurs, Qianmen uniform force can be made, not easily deformation, effectively can prevent the effusion of arc light, high-temperature gas and splashings, ensure that personnel and device security.
Accompanying drawing explanation
Fig. 1 is the stereogram of front door of switch cabinet.
Fig. 2 for after opening Qianmen depending on the stereogram being arranged on the latch hook system of inside, Qianmen.
Fig. 3 is the stereogram of the locked groove on cabinet doorframe.
Embodiment
Details of the present invention and operation principle is described in detail below in conjunction with accompanying drawing.
Contrast Fig. 1, can find out Qianmen 10 and door lock 15.Contrast Fig. 2, can find out the latch hook system being arranged on inside, Qianmen 10.Contrast Fig. 3 can find out that cabinet doorframe 12 is provided with the longitudinal locked groove corresponding with latch hook 13 and horizontal locked groove 14.
Latch hook system, by door lock 15, gear 16, gear bar 17, longitudinal jam plate 18, horizontal jam plate 19, arc connecting plate 20, latch hook 13 are formed, longitudinal jam plate 18 is equipped with latch hook 13 with horizontal jam plate 19, gear bar 17 is equipped with at the middle part of longitudinal jam plate 18, article two, horizontal jam plate 19 is connected with longitudinal jam plate 18 by two arc connecting plates 20 respectively, and the mandrel that gear 16 is fixed on door lock 15 engages with gear bar 17.
Door lock 15 handle is rotated clockwise after closing Qianmen, gear 16 driven wheel bar 17, drive the lengthwise movement of longitudinal jam plate 18, horizontal jam plate 19 transverse movement, latch hook 13 correspondence enters longitudinal locked groove on cabinet doorframe 12 and horizontal locked groove 14, Qianmen 10 is blocked, and rotate counterclockwise door lock 15 handle, Qianmen 10 is unlocked.
After Qianmen 10 is blocked, when there is arc fault in any compartment of switch cubicle, Qianmen 10 is confined by four sides, upper and lower, left and right, bear pressure uniform, avoid deformation, high-temperature gas, arc light and particle can not be overflowed at Qianmen 10, effectively ensure that operating personnel and device security.
