Abstract
The utility model discloses an air duct structure for a high-current switch cabinet. A bent plate (6) is arranged below a central partitioning plate (8) to form a relatively closed air intake passage with the central partitioning plate (8), a blower fan (4) is arranged at the inlet port of the air intake passage, three air openings are arranged on the central partitioning plate (8), which are just below three insulated canisters at working positions of a circuit breaker so as to allow the insulated canisters to be a part of the air duct, and an air shield (5) is arranged at the air outlet port of the blower fan. The air duct structure effectively solves problem of the poor watt dissipating capacity in the prior switch cabinet, and has the advantages of safe and reliable usage and convenient installation.
Description
Technical field
The utility model relates to the indoor ac high-voltage switch cubicle in a kind of electrical power distribution system, and is special relevant with the ventilation and heat structure of high-tension switch cabinet.
Background technology
Along with the develop rapidly of national economy, some large-scale electric substations, power plant and use under high load electrician ore deposit enterprise require the electricity capacity of switch cubicle increasing.Because its rated operational current of jumbo switch cubicle is very big, this just requires switch cubicle to have good ventilation and heat ability.General solution is only to install blower fan additional, because wind path is not concentrated, its heat-sinking capability is limited, only is used for little current switch cabinet at present.
Summary of the invention
The purpose of this utility model is the heat dissipation wind channel of a kind of high-current switch of design.
The technical solution of the utility model is: a bent plate is set below median septum, air intake passage with median septum formation relative closure, blower fan is arranged on this air intake passage porch, under three insulating cylinders in circuit breaker service position, the air port is arranged on the median septum, make insulating cylinder become the part in air channel, cold air can directly pass through from insulating cylinder fast, and rushes down the side opening waste cock cabinet of gland by the cabinet top.Fan outlet is provided with deep bead, during operate as normal, opens the air outlet of blower fan under fan action, makes wind path unimpeded; When faults such as generation arcing in the cabinet, under hot air acting, close the air inlet of blower fan, the blocking-up air channel avoids pressure to gush from the air inlet of switch cubicle, guarantees operating personnel's personal safety.
This air channel structure that the utility model provides needs parts few, makes full use of the switch cubicle own characteristic, and individual parts is improved, and has realized the integrality of air channel structure, and easy for installation.
Description of drawings
Accompanying drawing is the utility model switch cubicle air channel structure schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, Switch Insulation Cylinder 2, median septum wind hole 3, mounting panel 4, blower fan 5, deep bead 6, bent plate 7, rush down gland side opening 8, median septum A, air inlet
As shown in drawings, below median septum 8, be provided with a bent plate 6, air intake passage with median septum 8 formation relative closures, blower fan 4 is arranged on this air intake passage porch, three air ports 2 are arranged under three insulating cylinders 1 in circuit breaker service position on the median septum 8, make insulating cylinder become the part in air channel, cold air can directly pass through from insulating cylinder fast, and rushes down the side opening 7 waste cock cabinets of gland by the cabinet top.Deep bead 5 is installed on the air outlet of blower fan, during operate as normal, opens the air outlet of blower fan under fan action, makes wind path unimpeded; When faults such as generation arcing in the cabinet, under hot air acting, close the air inlet of blower fan, the blocking-up air channel avoids pressure to gush from the air inlet A of switch cubicle, guarantees operating personnel's personal safety.
The air direct when direction of arrow is normal operation of circuit breaker among the figure.
