Definitions
- the invention relates to a front cover for a module of a modular drive system having at least two modules, which are arranged spatially next to one another and are connected to one another in an electrically conductive manner by means of a DC voltage intermediate circuit.
- Such a modular drive system is known from the Siemens catalog DA 65.11 - 2001 with the title "SIMOVERT MASTERDRIVES Motion Control", chapter 6, in particular page 6/47.
- the modular drive system shown in Fig. 6/42 has a capacitor module, a supply module with control panel and seven inverter modules with different outputs. These modules are arranged side by side.
- the intermediate circuit busbars of these modules are made using a three-phase busbar system consisting of a plus, minus and PE busbar. Standard copper bars are provided as busbars. These busbars are insulated in a guide unit above the modules.
- the DC link voltage is generated in the supply module and supported by the capacitor module.
- the DC link voltage generated is distributed to all inverter modules using the three-phase rail system.
- the supply module generates a supply voltage of, for example, 24V, which is fed to the inverter modules using a two-core cable. This supply voltage is required to supply the electronics of the inverter modules.
- a further embodiment of a modular drive system is known from the Siemens catalog DA 65.4 - 2001 with the title “SIMODRIVE 611 universal and POSMO", chapter 6, in particular page 6/26.
- This drive system differs from the modular drive system already mentioned in that each module on the front side in the lower part of two the arranged intermediate circuit busbars, each having a connection bracket attached on one side and a contacting screw.
- the intermediate circuit busbars of an inverter module are electrically conductively connected to corresponding intermediate circuit busbars of an adjacent inverter module.
- Each connection bracket hooks onto a corresponding contact screw of the neighboring inverter module, which is then screwed on tightly.
- a vibration-proof contacting of the DC link busbars of two adjacent inverter modules is thus produced.
- These two busbars are covered by a protective cap, which is lined with an EMC sheet.
- This EMC sheet is electrically connected to a PE connection of a module by means of a line.
- each protective cap has spring contacts laterally so that the EMC sheets of the individual modules of a modular drive system are connected to one another in an electrically conductive manner. This means that a PE return conductor of this modular drive system is looped through all modules.
- the modules of this modular drive system are connected to each other at the front using a device bus.
- each module has a slot for a control module, which has a multi-pin socket on the front for connecting a device bus.
- each control module has additional multi-pole sockets on the front, one of which has terminals for forwarding a supply voltage.
- a disadvantage of the last-mentioned modular drive system is the space required for the two intermediate circuit busbars.
- the distance between these two DC link busbars is dimensioned so that when an inverter module is installed or removed from or to the modular drive system, the connection bracket of the lower or upper busbar cannot touch the upper or lower busbar. Consequently at the expense of the space requirement, it is ensured that the DC link of the modular drive system cannot be inadvertently short-circuited.
- handling the connection of the PE return conductor is time-consuming and prone to failure.
- a pre-assembled cable harness or several cables are required for looping through a supply voltage through all modules of a modular drive system.
- the invention is based on the object of developing the modules of a modular drive system in such a way that the disadvantages mentioned no longer come into play.
- the two intermediate circuit busbars are arranged in a step-like manner with respect to one another, the two intermediate circuit busbars can be arranged at a minimal distance from one another, regardless of the design of the connecting bracket. This significantly reduces the space required for the DC link busbars.
- the previous external wiring is no longer required. This means that a supply voltage can be looped through all modules of a modular drive system with little effort using these supply busbars and associated connectors. Since the front hood with the front
- Cover is pivotable and lockable, it is captive and prevents unauthorized persons from working on the DC link busbar of the modular drive system, since a tool is required to unlock it.
- the front cover is between the intermediate circuit busbars on the Rear of the cover arranged a busbar with a contact spring arranged on one side and a contact plate arranged opposite this.
- a PE return of the modular drive system is ground through all modules of this drive system simply by arranging the modules side by side.
- this arrangement of the PE return conductor means that the modular drive system is less susceptible to interference from EMC influences.
- the supply busbars have a shield plate.
- FIG. 1 shows a perspective view of an upper part of the front cover according to the invention
- FIG. 2 shows a side view of that shown in FIG
