Overvoltage protection device with concentric arcing horns

Abstract: An overvoltage protection device ( 1 ) with a first electrode ( 2 ) which has a first arcing horn ( 3 ), with a second electrode ( 4 ) which has a second arcing horn ( 5 ), with an air-breakdown spark gap ( 6 ) which is active between the arcing horns ( 3, 5 ), and with a housing ( 7 ) which accommodates the electrodes ( 2, 4 ), has the two arcing horns ( 3, 5 ) shaped and arranged relative to one another such that they diverge from a lower ignition area ( 8 ) to their outer ends ( 9, 10 ), so that the air-breakdown spark gap ( 6 ) widens outwardly, proceeding from the ignition area ( 8 ). The overvoltage protection device ( 1 ) has a current carrying capacity which is as high as possible and a high network follow current extinction capacity with an overall height which is as small as possible by the first arcing horn ( 3 ) being made in the shape of a truncated cone and the second arcing horn ( 5 ) being located concentrically around the first arcing horn ( 3 ).

Jumper, and structural unit comprising at least two modular electric terminals and a jumper

Abstract: A jumper is described that comprises a housing (2) and is used for bridging two modular electric terminals (3, 3') which are arranged next to one another and are each equipped with a busbar (4, 4'). At least one opening (5, 6, 7) is formed in the busbars (4, 4'). In order to be able to easily actuate the jumper according to the invention and flexibly and easily insert the same into multiple modular terminals, two mutually insulated contact elements (8) are arranged in the housing (2) so as to engage into an opening (5, 6, 7) in one respective busbar (4, 4'), and a jumper rail (9) is movably retained in the housing (2). The jumper rail (9), which has two contact zones (10) and a connection zone (11) that connects the contact zones (10), can be moved from a first final position in which the contact zones (10) do not contact the contact elements (8) into a second final position in which the contact elements (8) are interconnected in an electrically conducting manner via the jumper rail (9).

Advanced Monitoring, Diagnostics, Remote Indication and Testing of SPDs Connected to Telecommunications and Signalling Networks

Abstract: To protect telecommunications and signalling networks efficiently against man-made and lightning induced surges, reliable surge protective devices (SPDs) are needed. Sometimes SPDs get exposed to voltages and currents beyond their design limits. This can cause overheating in certain applications with relatively high prospective short-circuit currents. For the protection against overheating, new sophisticated thermal disconnect devices and new short-circuiting mechanisms got designed. During their commercial lifetime SPDs can degrade. It's highly desirable to monitor the ”State of Health” of SPDs in a way that ageing SPDs can be detected reliably. This allows to replace SPDs during preventive maintenance. In this paper advanced approaches to ”online” and ”offline” monitoring and to testing of SPDs are discussed - including Smart SPDs with integrated advanced monitoring features, network connectivity, cloud-based ”State of Health” evaluation and cloud-based monitoring of surge impulses.

Temperature measuring module having position compensation

Abstract: A temperature measurement module having position compensation provided for connection to at least one thermocouple includes a temperature-dependent resistor, via which a first temperature of a reference point of the thermocouple can be detected as a resistance voltage. The temperature measurement module includes an evaluation circuit which allows a first temperature value of a measurement point to be determined via the resistance voltage and a thermoelectric voltage of the thermocouple. The temperature measurement module includes a compensation mechanism which modifies the first temperature value depending on the installation position of the temperature measurement module so that thermal influences of the evaluation circuit, which have a thermal effect on at least one of the reference point or the measurement point depending on position, are compensated at least in part.

System cabling for a multiple relay arrangement

Abstract: The invention relates to a multiple relay arrangement consisting of a plurality of relay sockets (1) which are arranged next to each other and a plurality of relays (2). The relay sockets (1) contain additional plug connections (13) by means of which the relays (2) are controlled by the system cabling. Said system cabling contains a distribution section (53) consisting of cable sections (52) and plug connectors (33) and allows the plurality of relays (2) to be controlled.
