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.

Switchgear cabinet monitoring arrangement

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.

A switchgear cabinet monitoring arrangement with a monitoring unit (&Uuml;E) having a control device (ST), an indicator control and inputs for connecting sensors, outputs for connecting actuators, and a programming unit which is or can be connected with the monitoring unit, and with an indicator device. An improved adaptation to various uses of the switchgear cabinet is achieved because visual and/or acoustical notices for the distribution via the indicator device can be provided and changed by the programming unit and can be transmitted to the monitoring unit and stored in a memory device. As a function of the switchgear states detected via the sensors, the notices can be transmitted by the control device to the indicator device and can be displayed on the indicator device.
