Abstract
The utility model discloses a heavy current switch cabinet forced air cooling device comprising a middle separating plate (1) which is arranged on an air inlet of a switch cabinet. The middle separating plate (1) is provided with multiple ventilation grooves (1.1). The air inlet of the switch cabinet is internally provided with an installation plate (2) and a blower (3). The blower (3) is fixed on the external side of the installation plate (2) which is provided with a ventilation opening. The heavy current switch cabinet forced air cooling device is characterized in that the installation plate (2) is provided with a baffle plate device so that the ventilation opening can be covered or opened. An internal fire protection function can be realized by the heavy current switch cabinet forced air cooling device so that internal high pressure airflow and metal particles can be prevented from being sprayed out of the ventilation grooves.
Description
Technical field
The utility model relates to switch cubicle technical field, is specifically a kind of high-current switch air blast cooling device.
Background technology
High-current switch is because main circuit current is larger, inner produces a large amount of heats, as heat can not distribute in time, certainly will produce temperature rise and exceeds standard, and affecting switch cubicle performance even cannot normal power supply; Therefore for the common high-current switch of the normal operation of assurance equipment is mostly with forced air cooling device; conventional implementation is directly to install blower fan additional; switch board housing is driven ventilation slot; although this can realize forced air cooling function; but brought degree of protection to can not meet requirement simultaneously; and cannot realize inner arcing safeguard function, when internal fault, inner red-hot high pressure draught and metallic particles can spray from ventilation slot, threatens personal life and device security.
Utility model content
The technical problems to be solved in the utility model is, adopts and a kind ofly can realize inner combustion protective function, avoids inner high pressure draught and metallic particles from the high-current switch air blast cooling device of ventilation slot ejection.
The technical solution of the utility model is, a kind of like this high-current switch air blast cooling device of following structure is provided, comprise the median septum that is located at switch cubicle air inlet, described median septum is provided with a plurality of ventilation slots, in described switch cubicle air inlet, be provided with mounting panel and blower fan, described blower fan is fixed on the outside of mounting panel; Described mounting panel is provided with ventilating opening; Described mounting panel is provided with a retaining device that can cover or open ventilating opening.
Described retaining device comprises baffle plate and extension spring, and a side and the mounting panel of described baffle plate are rotationally connected, and opposite side is connected with extension spring, and the other end of extension spring is fixed on switch cubicle.
Described mounting panel is obliquely installed.
Adopt after said structure, the utility model compared with prior art, has the following advantages: blower fan is housed on mounting panel, has ventilation slot on median septum, the protection woven wire that can meet degree of protection is housed on ventilation slot, have extension spring on baffle plate.Normal condition lower baffle plate is opened, and blower fan drives cold air to carry out cooling to switch cubicle; When break down in inside, because internal pressure increases, when air pressure is greater than the pulling force of extension spring, powerful air-flow compressing causes flapper closure ventilation hole, avoids inner high pressure draught and metallic particles from ventilation slot is ejected into cabinet, can realize inside and fire protective function.
