Description
Technical field
The utility model belongs to a kind of corollary equipment that is used for the mains switch cabinet, is specifically related to a kind of mounting structure of switch cubicle cooling fan.
Background technology
The load of present domestic transformer station is increasing, and many transformer stations all adopt 4000A service entrance switch cabinet and bus connection switch cabinet.4000A switch cubicle running current is big, and it is very serious to generate heat, and the temperature rise speed at the many positions of switch cubicle (comprising bus-bar system, dividing plate, cabinet shell) is fast; Owing to the switch cubicle temperature rise, have a strong impact on the life-span of insulating part (comprising circuit breaker insulating cover, isolation knife insulating case and wall bushing etc.) in the cabinet, make switch cubicle have certain potential safety hazard.
In order to reduce the temperature rise of switch cubicle, people have installed cooling fan in switch cubicle, so that the heat that produces in the switch cubicle in time is discharged to beyond the housing, and the temperature rise of control cabinet inside.But, therefore often need the maintenance cooling fan, and existing cooling fan all is to be fixedly mounted in the switch cubicle, needs to have a power failure when overhauling cooling fan because this cooling fan palpus long-time running is difficult to reach the requirement of switch cubicle long-time running its useful life.Current power reguirements is more and more higher, stops the power supply at transformer station section even whole station in order to overhaul cooling fan, is that power supply department is difficult to accept and the realistic problem of having to accept.
Summary of the invention
The purpose of this utility model provides a kind of mounting structure of switch cubicle cooling fan, and its cooling fan can make things convenient for fast to be changed, and does not need to have a power failure when changing.
For achieving the above object, the mounting structure of switch cubicle cooling fan of the present utility model comprises switch cabinet body and cooling fan, its main feature is, horizontal guide rail is installed in the switch cabinet body, on the horizontal guide rail drawer can be installed slidingly back and forth, described cooling fan is installed in the inner chamber of drawer, and the installation direction of cooling fan up; The diapire of drawer is maked somebody a mere figurehead in the switch cabinet intracoelomic cavity, and the diapire of drawer offers ventilation hole; The rear wall of drawer is provided with attaching plug or supply socket, corresponding supply socket or the attaching plug of being provided with of switch cabinet body; Miniature circuit breaker and circuit breaker controlling organization also are installed in the drawer inner chamber, and the attaching plug of described drawer rear wall or supply socket, miniature circuit breaker, cooling fan series connection form the loop; The antetheca of drawer is concordant with the cabinet sidewall, in the antetheca outside of drawer operating grip is installed also, and operating grip is connected with the operation rotating shaft, and the operation rotating shaft is connected with the circuit breaker controlling organization.So-called " installation direction of cooling fan " is meant the direction that the air-blowing of cooling fan work space-time goes out.
Described drawer also is provided with drawer locking operating mechanism, and described operation rotating shaft is connected with drawer locking operating mechanism.
The utlity model has following advantage and effect:
1, when needs are changed or overhaul cooling fan, only need whole drawer is extracted together with cooling fan, immediately that another is standby then identical drawer is packed into and is got final product, and whole process is consuming time extremely short, can not influence the switch cubicle heat radiation substantially in replacing or maintenance process; And the antetheca of drawer is concordant with the cabinet sidewall, drawer is independent of outside the five-defence block of switch cubicle, extract or insert drawer unit out and needn't open cabinet Qianmen or back door, operating process does not need to operate five-defence block, whole process need not to require switch cubicle to be in the interruption maintenance state, can not influence normal power supply.
Description of drawings
Fig. 1 is the user mode schematic diagram of a kind of specific embodiment of the utility model.
Fig. 2 is the mounting structure schematic diagram of cooling fan among Fig. 1.
Embodiment
Switch cubicle shown in Figure 1 is provided with cabinet 18, lead bus unit 14, current transformer 15, circuit breaker dolly 13, drawer 4, cooling fan 3, and cabinet 18 is provided with air intake passage 16 and air-out passage 17.
The mounting structure of Fig. 1, cooling fan shown in Figure 2 comprises switch cabinet body 18 and cooling fan 3, crossbeam 1 is installed in the switch cabinet body 18, horizontal guide rail 5 is installed on the crossbeam 1, drawer 4 can be installed on the horizontal guide rail 5 slidingly back and forth, described cooling fan 3 is installed in the inner chamber of drawer 4, and the installation direction of cooling fan 3 up; The diapire 41 of drawer is maked somebody a mere figurehead in switch cabinet body 18 inner chambers, and the diapire 41 of drawer offers ventilating opening 42; The rear wall 43 of drawer is provided with supply socket 2, at the corresponding attaching plug 6 that is provided with of switch cabinet body; The supply socket 2 of drawer rear wall is corresponding with attaching plug 6 positions of switch cabinet body; Miniature circuit breaker 7 and circuit breaker controlling organization 8 also are installed in the drawer inner chamber, and the supply socket 2 of described drawer rear wall, miniature circuit breaker 7, cooling fan 3 series connection form the loop; The antetheca 44 of drawer is concordant with cabinet 18 sidewalls, in the antetheca outside of drawer operating grip 11 is installed also, and operating grip 11 is connected with operation rotating shaft 12, and operation rotating shaft 12 is connected with circuit breaker controlling organization 8.Described drawer also is provided with drawer locking operating mechanism 9, and described operation rotating shaft 12 is connected with drawer locking operating mechanism 9.
