Cortem electrical components Germany Cortem model Cortem price

Cortem electrical components refer to lightning arrestor tubes or antenna switch tubes used for overvoltage protection, which contain two or more electrodes and are filled with a certain amount of inert gas. A gas discharge tube is a gap-type lightning protection component used in the lightning protection of communication systems. Gas discharge tubes are gap-type lightning protection components that have been widely used in the lightning protection of communication systems. Discharge tubes are often used in the first or first two stages of multi-stage protection circuits to discharge instantaneous lightning overcurrents and limit overvoltages. Due to the very high inter-electrode insulation resistance and very small parasitic capacitance of the discharge tube, it has clear advantages for lightning protection of high-frequency signal lines. The main disadvantage of the discharge tube's protection characteristics is its large discharge delay and less-than-ideal operating sensitivity, making it difficult to effectively suppress lightning waves with a steep wavefront rise. There is also a follow-current issue in the lightning protection of power systems. Commonly used gas discharge tubes include two-electrode and three-electrode discharge tubes, and their encapsulation housing material is mostly ceramic, hence they are called ceramic discharge tubes.

Cortem electrical component structure

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, where the thermoelectric potentials output by each thermocouple are superimposed. Used to measure small temperature differences or average temperatures. Structure of a thermopile: the radiation receiving surface is divided into several sections, each connected to a thermocouple; connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made in wire type and thin film type, as well as multi-channel and array devices.

Cortem electrical component principle

The construction of a mercury switch is very simple. The exterior is a sealed cylindrical insulating housing containing approximately one-fifth mercury. Two wires led out from the inside are fixed at one end of the housing. This constitutes a mercury switch. Due to gravity, the mercury bead flows to the lower part of the container; if it contacts both electrodes simultaneously, the switch closes the circuit, turning the switch on. The shape of the container also affects the conditions under which the mercury bead contacts the electrodes.
