Description
Technical field
The utility model relates to a kind of unit cabinet of high voltage converter, exactly, relate to a kind of ventilation and heat passage of power model unit, the annular seal space that is used for the cooling power modular unit and formation thereof of cabinet inside, unit of high voltage converter and the mounting structure layout in control room, belong to the structure-design technique field of high voltage converter.
Background technology
Frequency converter is to utilize the switch on and off effect of power semiconductor device power frequency supply to be transformed to the electric energy inverter of frequency adjustable.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.
Referring to Fig. 1, introduce four chief components of high voltage converter:
Transformer case (A): isolating transformer is housed in the cabinet, and the many winding outputs of secondary for power cell provides independently phase shift power supply, can improve the current waveform of net side greatly, and reduction equipment is to the Harmonic Interference of electrical network.
Unit cabinet (B): power cell modular, that can exchange is housed in the cabinet, is convenient to produce and safeguard; Wherein the quantity of power cell depends on power output.Usually, 3 kilovolts unit cabinet is made up of 9 power cells, and per 3 power unit cascades become a phase, three-phase Y connection; 6 kilovolts unit cabinet is made up of 15 power cells, and per 5 power unit cascades become a phase, three-phase Y connection; 10 kilovolts unit cabinet then is made up of 27 power cells, and per 9 power unit cascades become a phase, three-phase Y connection.
Control cubicle (C): controller is housed in the cabinet, be used for the implementation space vector control and and power cell between optical-fibre communications, need 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.
Bypass cabinet (D): the switch of installing in the cabinet can be followed according to user's operating mode and requirement and be selected isolation switch, vacuum contactor or both compound modes for use.After frequency converter is out of service, by the bypass cabinet motor is dropped into the common frequency power network operation, with carrying out continuously of guaranteeing to produce.
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, 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, unit cabinet, control cubicle, bypass cabinet all can increase with the increase of electric pressure.Want to reduce as much as possible their volume, for transformer case, bypass cabinet and control cubicle, produce little effect.So making great efforts to reduce the volume of unit cabinet is the key that reduces frequency converter cabinet volume.
Referring to Fig. 2,6 kilovolts of unit cabinets introducing existing product remove unit installing structure figure behind the door, and 1 is the bulk metal framework among the figure, and 2 is annular seal space, and 3 is the power model unit, and 4 is the cooling vent of power model unit, and 5 is base.Directly over annular seal space 2, blower fan is housed, is used for air-supply and comes the cooling power unit.Adopt the structural advantages of the parallel placement of this every phase power model unit transverse to be: each power cell is concentrated, compact, can fully accept air-cooled.But if more the unit cabinet of voltage levels still adopts this version to place the power model unit, then its volume will increase greatly, and want to allow the power model unit fully cool off, and also need to increase blower fan quantity.Fig. 3 has showed the placement situation of 10 kilovolts of unit cabinet internal power modular units that adopt the said structure form: because every 9 power model unit are arranged mutually, its length reaches 2710mm, has increased 1000mm than the length (1700mm) of 6 kilovolts of unit cabinets (5 power model unit).If higher electric pressure, increasing degree is bigger.So big volume has all brought a lot of difficulties for packing, lifting, transportation and the heat radiation of equipment.Therefore, how to solve, just become the new problem that those skilled in the art are badly in need of solving owing to electric pressure rising, unit cabinet length and the excessive variety of issue that brings of volume increasing degree thereof.
