摘要:
The invention relates to a switch cabinet arrangement of a device for generating electrical energy, wherein the switch cabinet arrangement comprises at least two separate power switch cabinets. The technical object of achieving an optimum scalability of devices for generating electrical energy with at the same time a simple installation and maintenance of the power switch cabinets despite a small available installation space, is achieved according to the invention in that the power switch cabinets respectively comprise a machine connection, a power module, a mains connection and a decentralised control unit, wherein the power module comprises a machine converter, a mains converter, a direct voltage intermediate circuit and a chopper, and wherein the power switch cabinets are electrically connected in parallel to one another via the machine connection and the mains connection.

A modular pump control panel assembly consisting of multiple compartments arranged so as to allow service of each individual compartment without exposure to line voltages while still maintaining operation of the pumping system. The assembly includes a plurality of motor controller compartments each including a lockable handle operator that that is interlocked with its corresponding compartment door. The handle operators are mechanically connected to remote disconnecting devices via flexible cables or mechanical linkage. A key feature/distinction of this invention is that the disconnecting devices are not located in their corresponding motor controller compartments, so that when the handle operator is switched to the OFF position there are no components (e.g. disconnecting device and/or its supply conductors) within the motor controller compartment that remains energized by line voltage.

A control box arrangement including at least one control box which has a frame constructed from vertical and horizontal frame pieces and which is fitted with, or can be fitted with, mounting parts including mounting rails, for the variable design of the inside of the control box for the division thereof. The frame pieces have rows of mounting holes in a defined pattern. The division of the inside of the control box can be varied by single-component connection pieces for connecting the mounting rails to the frame pieces. The connection pieces include a coupling section which protrudes at a right angle from the connection plane of the associated frame piece when applied. The coupling section has a quadratic or rectangular cross-section and has at least one transversally extending threaded borehole. The four planes of the coupling section are parallel to the vertical plane and the horizontal plane of the control box.

A switchgear cabinet with a rack and/or panel elements, wherein a mounting plate can be attached to an interior of the switchgear cabinet. A lower edge of the mounting plate has sliding elements, wherein one or several spacing elements are fastened on a rear panel element and/or on rear parts of the rack, by which the mounting plate is supported in the mounting position. The mounting plate can provide fastening receivers in the area of the lower edge and the upper edge which, in the installation position of the mounting plate, cooperate with fastening elements of the lower and upper contact elements and fix the mounting plate rigidly in place. With sliding elements supported on the bottom or the cover plate and fastening elements at the spacing elements and fastening receivers on the mounting plate, an installation without sliding rails is possible, wherein the switchgear cabinet can be installed facing the attachment area with the bottom plate or the cover plate.
