Abstract
The utility model relates to the technical field of the structural design of a high-voltage frequency converter, and especially relates to a design of the control cabinet body of a series type high-voltage frequency converter. The control cabinet body is mainly composed of a transformer cabinet, a control cabinet, a control panel, an upper mounting plate, a lower mounting plate and a control panel support. The control cabinet is embedded in the transformer cabinet. The control cabinet body is reasonable in design, compact in structure, and convenient and reliable in mounting. A conventional independent control cabinet serves as the transformer cabinet of a high-voltage frequency converter for a component of the transformer cabinet, such that the body of the control cabinet is saved, the space is further saved, the material cost and the manufacturing cost of the cabinet body are saved, and the volume is more compact. Moreover, both the control cabinet body and the transformer cabinet body are simple in wiring, and the wiring distance is close, thereby working reliably and stably.
Description
Technical field
The utility model relates to the structure-design technique field of high voltage converter, particularly relates to a kind of control cubicle cabinet design of tandem high voltage converter.
Background technology
Frequency converter is to utilize the switch on and off effect of power semiconductor device that power frequency supply is transformed to the electric energy inverter that frequency adjustable saves.Along with development of social productivity, as a kind of novel product, high voltage converter is widely used in thermal power plant, oil, chemical industry, running water, mine, and numerous industry inner high voltage electric machine speed regulations such as metallurgy, energy-conservation, soft start and intelligent control.The effect of its control cubicle also has it important, and controller is housed in the cabinet, is used for optical-fibre communications between control and the power cell of implementation space vector, needs electrical isolation completely.In addition, the interface board of installing in the cabinet is responsible for the digital and analog signaling of system and is handled, to satisfy the requirement of different application occasion.
Because it is more to form the cabinet of high voltage converter, so its volume is also correspondingly bigger.Along with the extensive use of frequency converter, its technology is more and more ripe, and its outward appearance and structure are also proposed requirements at the higher level.Under the prerequisite that satisfies the prior art parameter, can reduce the trend that the frequency converter volume is a Future Development as far as possible.Because the volume of the transformer case in the frequency converter, power cabinet, control cubicle, bypass cabinet all can increase with the increase of electric pressure.Want to reduce as much as possible their volume, be that transformer case, power cabinet, bypass cabinet and control cubicle overall construction design in the frequency converter are reduced frequency converter cabinet volume is only key.
At present, frequency converter is made up of transformer case, power cabinet, bypass cabinet and four kinds of independent cabinets of control cubicle, at last through and cabinet connect with bolt.As shown in Figure 1, be the transformer case and the control cubicle cabinet outline drawing of present high voltage converter, its structure is made up of transformer case 1 and 2 two independent cabinets of control cubicle, and the volume ratio of frequency converter is bigger, if higher electric pressure, increasing degree is bigger.So big volume has all brought a lot of difficulties for installation wiring, packing, transportation and the heat radiation of equipment.Therefore, how to solve the variety of issue that electric pressure raises, the volume increasing degree of cabinet is excessive and bring, become the new problem that those skilled in the art are badly in need of solving.
The utility model content
The utility model provides the control cubicle cabinet design of a kind of simple in structure, ingenious, neat appearance, tandem high voltage converter easy for installation; Solved in the prior art and made its cabinet volume increase, the problem of many-sided difficulty such as the installation that is caused, packing, transportation because of electric pressure raises.
The control cubicle cabinet design of the tandem high voltage converter of the utility model, its structure mainly is made up of transformer case, control cubicle, control board, upper mounting plate, lower installation board and control board support, and said control cubicle is embedded in the transformer case.
The control cubicle cabinet design of the tandem high voltage converter of the utility model, said control board support is welded in the said transformer case.
The control cubicle cabinet design of the tandem high voltage converter of the utility model, said control board, upper mounting plate and lower installation board are separately fixed on the said control board support.
The control cubicle cabinet design of the tandem high voltage converter of the utility model, said control board, upper mounting plate and lower installation board all adopt screw to be connected with the control board support.
The control cubicle cabinet design of the tandem high voltage converter of the utility model, the inside of said transformer case is provided with centrifugal blower, and centrifugal blower is air-cooled to carrying out in the control cubicle.
Compared with prior art the beneficial effect of the utility model is: 1, the utility model adopts the control cubicle cabinet design of tandem high voltage converter; In high voltage converter, not only can save the cabinet of control cubicle; Master Cost, the manufacturing cost of further conserve space and cabinet, volume are compact more.2, also have greatly improved in frequency converter wiring and aspect of performance, make that the wiring of two cabinets is simple, the wiring distance is near, thus reliable operation, stable.3, cabinet right portions in transformer case front is as the control room.Not only saved control cubicle, and centrifugal fan 7 is inner through cabinet, also air-cooled (its back side panel is provided with ventilation hole) is carried out in the control room in passing.4, mounting panel and control board support are welded in the transformer case, make cabinet intensity more solid and reliable, and control board all adopts screw to be connected with the control board support with mounting panel, are convenient to dismounting behind the installation electric components, and firmly not yielding.
