oehlbach electrical components Germany oehlbach model oehlbach price

oehlbach electrical components are components that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance and only impedes changes in current. If the inductor is in a state with no current flowing through it, it will attempt to impede current flow when the circuit is connected; if the inductor is in a state with current flowing through it, it will attempt to maintain the current unchanged when the circuit is disconnected. Inductors are also known as chokes, reactors, and dynamic reactors.

oehlbach electrical component composition

1. Generally, a fuse consists of three parts: first, the fusible element, which is the core of the fuse and serves to cut off the current when it melts. For fuses of the same type and specification, the fusible elements must have the same material, identical geometric dimensions, minimal and consistent resistance values, and most importantly, consistent fusing characteristics. Household fuses are commonly made of lead-antimony alloy; second, the electrode part, usually consisting of two electrodes, which are important components connecting the fusible element to the circuit. They must have good conductivity and should not produce significant installation contact resistance; third, the support part. Since the fusible element of a fuse is generally thin and flexible, the support's role is to fix the fusible element and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not exhibit breaking, deformation, combustion, or short circuits during use. 2. Arc extinguishing device: Fuses used in power circuits and high-power equipment not only have the three general parts of a fuse but also include an arc extinguishing device. This is because the circuits protected by such fuses not only have large operating currents, but also high voltage across the terminals when the fusible element melts. Often, the fusible element may have melted (fused) or even vaporized, but the current is not interrupted. The reason is that arcing occurs between the two electrodes of the fuse at the moment of fusing due to the action of voltage and current. This arc extinguishing device must have strong insulation and good thermal conductivity, and be negatively charged. Quartz sand is a commonly used arc extinguishing material. 6. Fusing indication device: Some fuses have a fusing indication device. Its function is to cause a certain change in appearance after the fuse operates (melts), making it easy for maintenance personnel to detect, such as emitting light, changing color, or popping out a solid indicator.

oehlbach electrical component structure

The basic structure of a voltage transformer is very similar to that of a transformer. It also has two windings, one called the primary winding and the other called the secondary winding. Both windings are mounted on or wound around the iron core. There is insulation between the two windings and between the windings and the iron core, providing electrical isolation between the two windings and between the windings and the iron core. During operation of the voltage transformer, the primary winding N1 is connected in parallel to the line, and the secondary winding N5 is connected in parallel to instruments or relays. Therefore, when measuring voltage on high-voltage lines, although the primary voltage is very high, the secondary side is low voltage, ensuring the safety of operators and instruments.
