The first inversion unit 1 and the second inversion unit 2 are not controlled.
First inversion unit 1 includes multiple middle splenium parts with the second inversion unit 2 and has similar construction.With first
For inversion unit 1, as depicted in figs. 1 and 2, which includes inverter module 11, earthing switch 12, direct current
Hold 13, input rectifying unit 14, output filter unit 15, crowbar circuit 16, charging transformer 17 and a number of other direct current devices
18.In shown embodiment, inverter module 11 is three-phase module, and each phase module includes thermal component 111, cooling
Circuit can flow through these thermal components 111 to take away the heat in inverter module 11.Preferably, inverter module 11 is that can take out
Formula module out, i.e. each phase module of inverter module 11 all have " drawer type " structure, with being capable of a phase module quilt wherein
Convenient for the maintenance of other middle splenium parts in the first inversion unit 1 when extraction.Due to similar with the first inversion unit 1, second
Details are not described herein again for the construction of inversion unit 2.
The heat exchange unit 4 between the first inversion unit 1 and the second inversion unit 2 is arranged in as shared heat exchange list
Member, be capable of providing simultaneously flow through the first inversion unit 1, the second inversion unit 2 and shared control unit 3 cooling circuit (such as
Air-cooled circuit).Therefore, in the case where needing using two inversion units, compared to the scheme of two frequency conversion cabinets of arrangement, originally
This layout of the frequency converter cartridge assemblies of utility model can make the heat exchange unit 4 that will be shared and the first inversion unit 1,
Two inversion units 2 and shared control unit 3 are arranged in the same frequency-charger cabinet, to reduce economic cost, save sky
Between.
Certainly, this arrangement is not limiting.In fact, the inversion of the frequency converter cartridge assemblies of the utility model
The quantity of unit is not limited to two, can according to actual needs and the size of frequency conversion cabinet determines, and shared heat exchange
Unit 4 may be arranged at any position that can simultaneously effective cool down all inversion units and its control unit, i.e. shared heat
The position of crosspoint 4 only needs to ensure that the heat exchange unit 4 is capable of providing to flow through all inversion units and its control unit
Cooling circuit.
In shown embodiment, heat exchange unit 4 is air-cooled including that can provide in the frequency converter cartridge assemblies
At least one blower 41 in circuit and 2 downstream of the first inversion unit 1 and the second inversion unit is arranged in along the air-cooled circuit
Heat exchanger 42.As non-limiting example, two blowers 41 being sequentially arranged along the vertical direction are shown in Fig. 1.It is true
On, the type and quantity of blower 41 can be determined according to practical radiating requirements.
Fig. 4 be include Fig. 1 to frequency converter cartridge assemblies shown in Fig. 3 a kind of frequency converter modular diagram.Such as Fig. 4
Shown, the frequency converter includes frequency-charger cabinet 7 and the above-mentioned frequency converter cartridge assemblies that are arranged in frequency-charger cabinet 7, the frequency converter
The antetheca 61 of the core shell 6 of cartridge assemblies is not closed, and the frequency converter cartridge assemblies can be made by offering on the antetheca 61
Each opening that the inner wall of each frequency converter unit and frequency-charger cabinet 7 is in fluid communication, even if sharing control unit 3 and frequency-charger cabinet
First opening 611 of 7 inner wall fluid communication makes the second of the inner wall of the first inversion unit 1 and frequency-charger cabinet 7 fluid communication to open
Mouthfuls 612, third opening 613 that the inner wall of the second inversion unit 2 and frequency-charger cabinet 7 is in fluid communication and make heat exchange unit 4 with
The 4th opening 614 that the inner wall of frequency-charger cabinet 7 is in fluid communication, these openings can make the frequency converter cartridge assemblies and frequency-charger cabinet
7 limit the channel in air-cooled circuit jointly.According to a kind of implementation modification, core shell 6 also may not include antetheca 61.
Three partitions 5 extend along the direction vertical with the antetheca 61 of core shell 6 and rear wall 62 and parallel arrangement is in machine
In core housing 6 so that share control unit 3, the first inversion unit 1, heat exchange unit 4 and the second inversion unit 2 from a left side to by
It successively separates, and defines three sub-air channels, i.e., across the first sub-air channel F1 of shared control unit 3, across the first inversion
Second sub-air channel F2 of unit 1 (i.e. across the thermal component 111 of inverter module 11) and across the second inversion unit 2 third son
Air duct F3.The rear wall 62 of these three partitions 5 and core shell 6 is separated with gap, can make to flow out the air of these three sub-air channels
Rear wall 62 along core shell 6 converges.
Solid arrow in Fig. 4 shows the air-cooled circuit in the frequency converter.When blower 41 start after, from blower 41 to
The air of preceding blowout is flowed out from heat exchange unit 4 up to frequency conversion cabinet via the 4th opening 614 on the antetheca 61 of core shell 6
Then 7 antetheca 71 is shunted along the antetheca 71 of frequency conversion cabinet 7 towards left and right, then via first on the antetheca 61 of core shell 6
The 611, second opening 612 of opening and third opening 613 respectively enter the first sub-air channel F1, the second sub-air channel F2 and third sub-air channel
F3 is flowed out with cooling shared control unit 3, the first inversion unit 1 and the second inversion unit 2 respectively from these three sub-air channels respectively
Air finally converge to heat exchanger 42 along the rear wall 62 of core shell 6, to be realized via heat exchanger 42 and external environment
Heat exchange.Due to the rational design of air-cooled return passage, heat exchange unit 4 is realized to shared control unit 3, the first inversion list
It is cooling while member 1 and the second inversion unit 2, meet the higher radiating requirements of the frequency converter cartridge assemblies.
Preferably, heat exchanger 42 is air/water heat exchanger, to be taken away in air-cooled circuit by the water being externally entering
Air heat.In shown embodiment, the ontology of inlet pipeline 421 and outlet pipeline 422 from heat exchanger 42
Extend back and sequentially pass through the rear wall 62 of core shell 6 and the rear wall 72 of frequency conversion cabinet 7 so that the heat exchanger 42 with should
The external of frequency converter realizes water flow transmission.
Certainly, the position of the inlet pipeline 421 of heat exchanger 42 and outlet pipeline 422 is not limitation.According to one
Kind implements modification, and inlet pipeline 421 and outlet pipeline 422 can upwardly extend from the ontology of heat exchanger 42 and sequentially pass through machine
The upper wall of core housing 6 and the upper wall of frequency conversion cabinet 7.In fact, inlet pipeline 421 and outlet pipeline 422 may be arranged at not with
Other any positions that the position of one inversion unit 1 and the second inversion unit 2 interferes." interference " herein be interpreted as due to
There are the first inversion unit 1 and the second inversion unit 2, it is inverse that inlet pipeline 421 and outlet pipeline 422 can not extend through first
Become the position of unit 1 or the second inversion unit 2.
The technology contents and technical characterstic of the utility model are had revealed that above, it being understood, however, that in the utility model
Under creative ideas, those skilled in the art can make various changes and improve to design disclosed above, but belong to this reality
With novel protection scope.The description of above embodiment is exemplary rather than restrictive, the protection of the utility model
Range is determined by claim.
