A switchgear cabinet or rack comprises a mounting unit with vertical mounting sections laterally delimiting a cabinet frame for installed user-side units, said sections having flat fixing sections that lie on a front mounting plane used to fix laterally projecting mounting sections of the installed units, and comprising components for determining the presence of an installed unit in an installation position of the cabinet frame. A vertical antenna strip contains antenna elements and code carriers as transponder elements. In order to ensure the secure installation and reliable functioning of the detection device, each transponder element is attached to the mounting section of the associated installed unit that adjoins the antenna strip by a retaining element via a connecting section and the retaining element has a support section that adjoins the connecting section and projects outwards, parallel to the mounting plane. The transponder element is attached to the support section.

A switchgear cabinet or rack comprises a mounting unit with vertical mounting profiles laterally delimiting an installation space. Flat fixing sections lie on a mounting plane to fix laterally projecting mounting sections of installed units and comprise components of a detection device for determining the presence of an installed unit in the installation space. A vertical antenna strip is attached to a mounting section and contains antenna elements. Code carriers designed as transponder elements are provided on the installed units. The front face of the antenna strip lies on or is set back by a maximum of 10 mm from said plane, with each transponder element in front of the front face of the antenna strip, fixed to a support section of a retaining element that overlaps the antenna strip, said retaining element being attached to the neighboring mounting section of the associated installed unit by a connection section.

The invention relates to a switchgear cabinet or rack comprising a mounting unit, the front of which has vertical mounting profiles that laterally delimit an installation space for installed user-side units, said profiles having fixing sections for attaching mounting sections of the installed units, and comprising components of a detection device for determining the presence of an installed unit in an installation position of the installation space. he components of the detection device have a vertical detector strip that is attached to a mounting profile and contains detector elements associated with the installed positions and arranged on or in said strip and code carriers that are provided on the installed units, the information from said carriers being transmitted for evaluation via the detector elements to a monitoring and control unit, either wirelessly or by wire. Clearly-represented user information is achieved for the switchgear cabinet using light elements mounted on or in the detector strip, said elements being associated with the installation positions and achieved by the fact that the light elements can be controlled in accordance with the information in the code carriers.

The invention relates to a switchgear cabinet or rack comprising a mounting unit, the front of which has vertical mounting profiles that laterally delimit an installation frame for installed user-side units, the front of said profiles being provided with flat fixing sections for attaching laterally projecting mounting sections of the installed units, and comprising components of a detection device for determining the presence of an installed unit in an installation position of the installation frame. The components of the detection device have a vertical detector strip that is attached to a mounting section and contains detector elements and code carriers that are provided on the installed units. To achieve a simple assembly with a precise allocation of the components of the detection device, the mounting section has a cavity that is at least partially adapted to the cross-section of the antenna strip, is open at the front and is located laterally outside the neighboring fixing section, an abutment section that is set back in relation to the plane of the fixing section at least by the cross-sectional depth of the detector strip and an inner boundary wall that delimits the cavity on the side facing the installation space.

Equipment that is housed in at least one switchgear cabinet or rack on the user side, or equipment that is to be supplied with electricity can be or is connected to the electric supply device. To achieve simple and reliable connection options, a sub-distribution device is located in the switchgear cabinet or rack or in a separate cabinet or rack. The device has at least one sub-distribution unit that can be or is connected to the primary power supply, having a housing or frame and being retained and secured by a mounting unit. According to this invention, the sub-distribution unit can be or is connected to primary supply lines that lead to the primary power supply and to pre-fabricated connection lines that lead to the rack.

Switchgear cabinet assembly or rack assembly

A liquid cooling system having cooling units individually assigned to electronic component groups housed in a rack or a switchgear cabinet, which are to be cooled, and having a monitoring and control arrangement for monitoring a cooling temperature. Effective cooling and temperature monitoring is obtained because the cooling units are liquid cooling units and are connected via branch points to a common central liquid line system integrated into the rack or the switchgear cabinet. The control and monitoring arrangement is for monitoring the cooling temperature in the central liquid line system and for emitting an error signal when a predetermined or a predeterminable threshold temperature in a liquid return branch is exceeded, or when a predetermined or predeterminable threshold temperature difference between a temperature in an inlet branch and a temperature in the return branch is exceeded, or when the liquid flow falls below a predetermined or predeterminable threshold value.

Liquid cooling system

A method and a device for detecting leaks in components conducting liquids by a sensor reacting to leaks. The component to be monitored is inserted into a closable envelope containing the leaked liquid. Electrodes are embedded into the envelope. The resistance and/or the capacitance between the electrodes is changed if leaking liquid enters the closed envelope. With a sensor connected to the electrodes, which reacts to the resistance and/or capacitance changes, a display and/or alarm signal is triggered. It is possible to monitor the entire component for leaks.

Method for the detection of leaks in components conducting liquids and device for executing the method

A switchgear cabinet monitoring and control arrangement with several switchgear cabinet monitoring and control devices connected to a network, and with at least one personal computer, which is in communication with the devices through the network. Simple operation is achieved because the at least one personal computer is connected to the network by a web browser. A server is assigned to a group of the switchgear cabinet monitoring and control devices, in which a management device containing information regarding the switchgear cabinet monitoring and control devices stored therein and including their respective identification, is arranged. The information can be called up using the at least one personal computer.

Switchgear cabinet monitoring and control arrangement

A switchgear cabinet monitoring arrangement with a control device for monitoring switchgear cabinet functions, including a door position, and for generating monitoring signals for signaling to and/or controlling components relating to the switchgear cabinet functions and installed in the switchgear cabinet or on the switchgear cabinet. A simple and compact design is achieved because the control device is limited to monitoring preselectable threshold values, a door position switch is installed on or in the device housing, and the device housing has one or several indicator elements which react with a visual or acoustic indication when at least one threshold value is upwardly or downwardly exceeded.

A switchgear cabinet including a smoke indicator which has an intake pipe and, in a housing, a smoke sensor as well as a fan or ventilator, which draws air from the interior of the switchgear cabinet into the housing via an inlet aperture in a housing wall and discharges the air via an outlet into the space outside the housing. A sensitive smoke indicator, which is also usable with the switchgear cabinet partially open, has the intake pipe communicating by its upper end region with the inlet aperture. The housing which is enclosed in a sealing manner apart from the intake pipe and the outlet, is disposed in the interior of the switchgear cabinet.

Switchgear cabinet including a smoke indicator means

A switchgear cabinet monitoring arrangement having a monitoring unit with several inputs for connecting sensors, as well as several outputs connected with the inputs via a linkage device for the connection of actuators, and having a programming unit. An adaptation to various uses is available because the linkage device is designed with connections between the inputs and the outputs, which can be preset and changed by means of the program unit.

A switchgear cabinet monitoring arrangement having a base monitoring device which is arranged or intended to be arranged in a switchgear cabinet and has at least one bus connection, several sensor connections and at least one triggering connection, for monitoring, controlling and/or regulating switchgear cabinet functions. Various monitoring and control functions of several different switchgear cabinets, along with a relatively simple construction, are achieved because a further monitoring device arranged or to be arranged in a respective further switchgear cabinet is assigned to the base monitoring device, which is connected to the base monitoring device by a field bus. The further monitoring device also has several sensor connections and at least one triggering connection and is designed for monitoring, controlling and/or regulating switchgear cabinet functions.
