DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1A shows a front view of the converter cabinet according to the first embodiment (the front door has been removed).In the converter cabinet 1, a plurality of converter modules 2 are arranged in two rows. They are arranged one on top of the other. Each converter module has two half cylinders 2a and 2b, which are connected to each other by a half cylinder flange 2c. In this embodiment, a total of five converter modules 2 are provided, three of which are stacked vertically in the first module row, and another two
The modules are stacked vertically in a second row of modules. These modules are rectifier or inverter units. One module row has two rectifier modules, for example for converting an alternating current voltage into a direct voltage, and the other module row has three phases of an inverter converting a direct voltage into a three-phase voltage. Three inversion devices are provided. Each converter module 2 has a plurality of module plug-in electrical contacts 3. When the module 2 is inserted, this contact piece engages in the corresponding conductor bar insertion device 4 on the cabinet side. This conductor bar insertion device 4 is fastened to a vertically running conductor bar 5. The vertical assembly of the converter modules within the converter cabinet has the advantage that the cross-coupling that necessarily occurs between the conductor bars and the electronics cables is minimized.

A plurality of support capacitors (Stuetzk
In this embodiment, the support capacitors 6 are stacked in six rows each having three support capacitors arranged horizontally. Rubber seats 6a are provided between two horizontally arranged support capacitors 6, and are tightened with setscrews 6b. The connections between the supporting capacitors 6 and between the supporting capacitors 6 and the conductor bars 5 are evident in FIG.

The converter module 2 is normally liquid-cooled, preferably oil-cooled. That is, the heat loss generated during use is transferred from the converter cabinet 1 through the liquid circuit or oil circuit, and is exhausted to the outside air via the external cooler. For the transfer of cooled oil to the converter cabinet 1 and the transfer of heated oil from the converter cabinet 1, a vertical support is provided near the back plate of the cabinet.
Liquid sending profiles 7, ie, one outgoing profile 7a, 7b and one return profile 7c, 7d are provided for each converter module row. The outward profile 7a is provided with an oil supply flange 8, and the return profile 7c is provided with an oil discharge flange 9. Lines leading to an external cooler are connected to these flanges 8,9. In order to connect the two outgoing sections and the two return sections, another horizontally arranged support/liquid section 10, specifically, the horizontal outgoing section 10a is connected to the vertical outgoing section 7a, 7b, and the horizontal return side profile 10b
is provided between the vertical return side sections 7c and 7d. This supporting/liquid-feeding profile 7 is used both as an oil frame for guiding oil and as a support for providing a mechanically rigid structure for the converter cabinet. In addition to oil, a liquid such as ordinary water or deionized water can be used as required.

After installing the converter module in the converter cabinet, using a suitable tool (not shown),
Once the module is locked, there is no need for a quick-seal joint 12 with any other special locking device.

Support and cable duct profiles 11 are arranged along both front edges of the converter cabinet on both sides of the support capacitor 6 and oriented vertically towards the front. This profile 11 is used to guide cables for electronic devices, control lines, power lines, etc. to predetermined locations, and also as a support to provide a mechanically strong structure to the converter cabinet. The connection between the gate units of the individual converter modules 2 and the corresponding cables or wires passed through the support and cable duct profile 11 takes place via plug-in contacts.

[0014] A converter module generally includes not only the converter rectifying elements but also the necessary circuit elements such as chokes, capacitors, resistors, diodes. Generally, the structure of the converter module is as follows. That is, the semiconductors of the module, such as GTOs and diodes, have a vertically assembled structure as a fixed assembly, spatially connected on one side to an external conductor bar or support capacitor arranged on the front side of the converter cabinet and on the other side also on the front side. electronic drive means. On the other hand, circuit elements and chokes close to the GTO are generally arranged at the full depth of the cabinet, toward the rear wall of the cabinet.

FIG. 1B shows a plan view of the converter cabinet of the first embodiment (however, the cover plate has been removed in this figure).
The fluid circuit communication between c, 7d and the converter modules 2 takes place via quick-seal joints 12, each converter module 2 having two such joints 12. One of the joints 12 is used for the outgoing oil path, and one is used for the return path. Also, the capacitors 6 are connected to each other by the capacitor connection path 14, and the capacitor 6 and the conductor bar 5 are connected to each other by the capacitor connection path 14.
The connection between is made by a connecting bar 13. Furthermore, FIG. 2 shows the slightly open front door 15 and the module plug-in contact surface 3 being gripped by the bar plug-in device 4 which is connected to the conductor bar 5 . Also support/
The shape of the U-shaped cross section of the cable duct profile 11 is also clearly indicated. After the electronic wires have been inserted, the opening in the profile is closed with a cover plate.

FIG. 2A shows a side view of the converter cabinet of the first embodiment. However, the side walls have been removed. FIG. 2A will be explained in detail below. In the diagram,
The vertical support/cable duct profile 11 on the front side, the vertical support/conveying profile 7 on the back side and the horizontal connection profile 16 connecting the two profiles 7, 11 are shown. The horizontal connection and rail profile 16 serves on the one hand as a support for the mechanically rigid structure of the converter cabinet and on the other hand for guiding the rollers 17 of the converter module 2. The converter module 2 has four converters on the upper side and four on the lower side.
The converter module 2 can be easily inserted into and removed from the converter cabinet 1 by means of two rollers 17 on each horizontal side edge of each side surface.

A centering guide pin 18 fixed to the back plate of the converter cabinet 1 engages with a guide hole 19 provided on the back side of the converter module 2 when the module is inserted. Optionally, the guide pins 18 can also be provided in the converter module and the guide holes 19 in the converter cabinet. In this case, the quick seal joint 12 can be easily and accurately connected by making preparations in advance. Depending on selection, the converter module 2 can also be inserted into the converter cabinet with the upper side facing down and the lower side facing up. This provides the advantage that the same converter module 2 can be inserted into either the left or right module row of the cabinet 1. In this case, the plug contacts are in each case directed towards a support capacitor 6 arranged between two rows of modules and a conductor bar 5 fixed vertically thereon.

Regardless of whether the module is inserted into the left or right module row, the oil circuit inside the module 2 must always reliably flow in the same predetermined direction. For this purpose, the refrigerant 7a, 7 on the outgoing side of the supporting/liquid-feeding shape member is
b, and the return side sections 7c and 7d are shown in (A) and (B) in Fig. 1.
They are arranged in the order shown. That is, the outgoing side profile 7a,
7b is along the rear outer edge of the cabinet, and return side sections 7c, 7d are arranged between these outgoing side sections.

In order to increase the stability of the converter cabinet, braces 20 are provided between the connection/rail profile 16 and the support/conveying profile 7 and between the connection/rail profile 16 and the support/cable duct profile 11. It is placed at the joint between the two. FIG. 2A further shows the front door 15 of the cabinet 1, the horizontal support/liquid feeding profile 10a, and the gate unit 21 of the converter module 2.

The above-described modular construction of the converter cabinet not only has the advantage that converter modules can be easily replaced in the event of a failure, but also can be used for a disconnector function. To do this, the module plug-in contacts 3 of the converter module are pulled out of the bar plug-in device 4 and the module is locked in this disconnected position until the required electrical contact spacing for the disconnector function is achieved at the predetermined voltage. As a result, the power supply section that supplies power to the converter and the converter are cut off, and the converter and the load to which power is supplied are cut off, making it possible to eliminate the need for a conventional auxiliary disconnect switch.

FIG. 2B shows a front view of the converter cabinet of the second embodiment. This embodiment differs from the first embodiment mainly in the following points. That is, the inserted converter modules 23 are not stacked vertically in a plurality of stages in the converter cabinet 22, but are placed, for example, in one three-phase converter module 23 on the left and right sides of the support capacitor 6 disposed in the center. It is placed as. However, this converter module 23 includes a set of rectifiers equipped with a protection device, such as a short-circuit protection device, or a set of three-phase inversion devices for all phases. Further, the converter frame 23 is movable by the truck frame 24 provided with the rollers 17, and can be easily inserted into and removed from the cabinet 22. The converter module 23 has a transverse module plug-in contact piece 3, as already mentioned in the first embodiment.
