Inotec electrical components are instruments that measure by converting high primary current to low secondary current based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series in the circuit where the current needs to be measured. Therefore, the full line current often flows through it. The secondary winding has many more turns and is connected in series in the measuring instrument and protection circuits. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils connected in series in the measuring instrument and protection circuits is very small, and the operating state of the current transformer is close to a short circuit. The current transformer converts high primary current to low secondary current for measurement; the secondary side must not be open-circuited.

Inotec electrical component principles

The working principle of a discharge tube is gas gap discharge. i When a certain voltage is applied between the two poles of the discharge tube, an uneven electric field is generated between the poles. Under the action of this electric field, the gas inside the tube begins to ionize. When the external voltage increases to the point where the field strength between the poles exceeds the insulation strength of the gas, the gap between the two poles will break down and discharge, transforming from the original insulating state to a conductive state. After conduction, the voltage between the two poles of the discharge tube is maintained at the residual voltage level determined by the discharge arc channel. This residual voltage is generally very low, thereby protecting electronic equipment connected in parallel with the discharge tube from overvoltage damage.

Inotec electrical component functions

(1) often compares the functions of sensors to the 5 major sensory organs of humans: photosensitive sensors for vision, acoustic sensors for hearing, gas-sensitive sensors for smell, chemical sensors for taste, and pressure-sensitive, temperature-sensitive, and fluid sensors for touch. (2) Classification of sensitive elements: Physical category, based on physical effects such as force, heat, light, electricity, magnetism, and sound. Chemical category, based on the principles of chemical reactions. Biological category, based on molecular recognition functions such as enzymes, antibodies, and hormones. Usually, they can be divided into ten major categories according to their basic sensing functions: thermal elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic-sensitive elements, humidity-sensitive elements, acoustic-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements (some have also classified sensitive elements into 55 categories).

Inotec electrical component structure

Three basic configurations of fiber optic sensor networks. Fiber optic sensor networks have three basic configurations, one of which is called the single-point sensor. Here, a single fiber optic cable serves only as a transmission medium. Another type is the multi-point sensor, where a single fiber optic cable connects many sensors in series, allowing many sensors to share a light source to achieve networked monitoring. Then there is the intelligent fiber optic sensor. Multi-point fiber optic sensors appear externally as a section of grating, with periodic intervals discovered through ultraviolet irradiation. When light is incident on the fiber, if the wavelength of the light exactly equals twice the interval, the light wave will be strongly reflected. If the fiber is subjected to temperature changes or strain, etc., this reflected wavelength will change. Many such sensors can be made on a single fiber, and connecting them allows for various sensing applications. Because fiber optics are flexible, they can be arranged in two-dimensional and three-dimensional spaces, so the horizontal axis represents spatial position, and the vertical axis represents the measurement object. What problems does such a sensor network solve? It solves the problem of what happened at what location and the intensity of that event, thereby providing two-dimensional information. This is the problem that intelligent fiber optic sensors need to solve. They have very prominent requirements, including small size, high strength, good stability, and implantability in materials. They are resistant to electromagnetic interference and environmentally durable.
