An arrangement and a process for monitoring an electrical safety interlock, based on the task of providing a solution with which affordable and robust monitoring in a safety interlock is facilitated and the overall complexity of the circuitry is reduced. This task is resolved on the arrangement side by the separate circuit being connected to a signal generation and evaluation unit that generates a continuous and value-discrete signal. On the process side, the task is resolved by the monitoring of the circuit being performed using a continuous and value-discrete signal, which is provided by a signal generation and evaluation unit and whose transfer via the circuit is evaluated by the signal generation and evaluation unit.

Arrangement and process for monitoring an electrical safety interlock

The invention, which relates to a choke arrangement () for application in an EMC filter, has as its objective specifying a choke arrangement () that is mechanically robust and that enables improved insulation of the windings (). The objective is attained by disposing about the toroidal core () a two-part enclosure () and by disposing an insulation web () in the two-part enclosure ().

The invention which relates to an EMC filter () addresses the problem of specifying an EMC filter () that is simple of structure, cost-effective and temperature resistant. This problem is resolved thereby that the core of the choke () is comprised of one or two core parts (), that at least one first planar or convex heat transfer area () is located on an outside of the core and that the core with this first planar or convex heat transfer area () is disposed on a housing () of the refrigerant compressor, wherein the housing () in the region of the first planar or convex heat transfer area () is implemented planar or concave.

A high voltage (HV) safety lock for HV components in a vehicle has an HV plug, including a safety bridge arranged in the HV plug and connected to a central vehicle control via an internal bus system within the vehicle or a simple switched signal via a decentral control and regulating unit of an HV component. The safety bridge is connected to an LV power supply configured with electric isolation from the HV system.
