Converter technique is used more and more extensive in our productive life, the especially mining situation of popularizing that reached.Existing frequency converter adopts the vertical structure layout, but the shockproof properties of vertical structure layout is not high, and running into emergency case may be damaged.And the radiator of existing frequency converter inside generally all adopts heat-pipe radiator, and the manufacturing process of this radiator is complicated, but effect is general, dispels the heat also unhappy.Therefore be badly in need of the mining anti-explosion frequency converter that a kind of shockproof properties is high and the manufacturing process simple effects is good.
The utility model content
In order to address the above problem, the utility model provides the mining anti-explosion frequency converter that a kind of shockproof properties is high and the manufacturing process simple effects is good.
A kind of mining anti-explosion frequency converter in the utility model, comprise casing, control device and terminals, described casing internal upper part is provided with control device, the bottom is provided with the air channel, is provided with radiator in described air channel, and described terminals are connected with control device, described radiator is fin-inserted radiator, described fin-inserted radiator comprises base plate of radiator and fin, and several fin are installed on described base plate of radiator, and described body structure adopts horizontal type structure.It is cooling, convenient and swift that fin-inserted radiator does not need other equipment to get final product nature in small-sized explosion-proof frequency converter.
In such scheme, also comprise explosion-proof fan, described explosion-proof fan is connected with the air channel and to the radiator air blast.In large-scale explosion-proof frequency converter, the use of explosion-proof fan makes radiator to dispel the heat faster.
In such scheme, also comprise water pipe, described water pipe is connected with the air channel and to the radiator water delivery.
In such scheme, described casing comprises upper cover and base plate, covers on described and is provided with handle, and described casing is provided with button and knob.Button and knob have facilitated operability.
In such scheme, described terminals are provided with the wire connection cavity lid.The wire connection cavity lid has been protected terminals.
In such scheme, be provided with radiator base plate between described control device and radiator.
In such scheme, the outside, described air channel is provided with the air channel rubber blanket.
In such scheme, described terminals comprise three binding posts.
In such scheme, also comprise protective plate, described protective plate is located at the both sides of casing.Protective plate has better been protected frequency converter.
Advantage of the present utility model and beneficial effect are: the utility model provides the mining anti-explosion frequency converter that a kind of shockproof properties is high and the manufacturing process simple effects is good.Owing to adopting the horizontal type structure layout, not only saving resource, improved utilance, more greatly improved the shockproof properties of product.Inner radiator adopts fin-inserted radiator, can naturally cooling, air-cooled, water-cooled mixed structure, and configuration convenient according to the operating mode needs, and manufacturing process is simple, and effective, also greatly reduce cost.Product with compact structure, the convenient installation and maintenance.
