Abstract
The utility model discloses a four-quadrant explosion-proof frequency converter installation device which comprises a base and a shell fixed on the seat. Two ends of the shell are respectively provided with wire inlet terminals. Two sides of the shell are respectively provided with a cabinet door and a heat radiator cover. The top of the heat radiator cover is provided with a fan. The four-quadrant explosion-proof frequency converter installation device has the advantages of small size, easy arrangement, good installability and good maintenance, and the device can be widely applied to the field of electric drive.
Description
Technical field
The utility model relates to electric drive field, particularly relates to a kind of four-quadrant explosion-proof frequency converter erecting device.
Background technology
Frequency converter is the electric control appliance of applying converter technique and microelectric technique, controlling alternating current motor by changing machine operation supply frequency mode.Explosion-proof frequency converter is mainly used under coal mine to be had in the dangerous explosion environment such as coal dust, gas, wherein, four-quadrant explosion-proof frequency converter can feed back to electrical network by the inertia energy of load, and have regeneration function and a braking function, the occasion such as potential energy load and the anxious large inertia load slowing down that is suitable for having electric energy regeneration and energy-conserving and environment-protective demand, is mainly used in the speed governing of descending belt conveyer, elevator and winch etc. in colliery.In view of these advantages, four-quadrant explosion-proof frequency converter under coal mine, the application in the inflammable and explosive property place such as dust atmosphere is increasingly extensive.With respect to common frequency converter, the environment that four-quadrant explosion-proof frequency converter is faced is harsher, especially higher to the installability of complete machine structure and maintainable requirement.And current four-quadrant explosion-proof frequency converter, not only movement installation and maintenance inconvenience, and also volume is large, is difficult for arranging.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, and a kind of four-quadrant explosion-proof frequency converter erecting device is provided, and makes it have little, the easy layout of volume, installability and maintainable good feature.
A kind of four-quadrant explosion-proof frequency converter erecting device that the utility model provides, comprise on base, described base and be fixed with housing, described housing two ends are respectively equipped with input terminal, and the both sides of described housing are respectively equipped with cabinet door and radiator cover, and described radiator cover top is provided with blower fan.
In technique scheme, described case top is provided with wire connection cavity, and described input terminal is located at wire connection cavity two ends, and described wire connection cavity top is provided with wire connection cavity lid.
In technique scheme, described cabinet door has two, arranges along shell length direction.
In technique scheme, described blower fan has two, arranges along radiator cover length direction.
Four-quadrant explosion-proof frequency converter erecting device of the present utility model, has following beneficial effect: owing to being arranged in a housing, this device has little, the easy layout of volume, installability and maintainable good feature.
