ELEKTROBOCK electrical components are indispensable measuring instruments for departments such as power electronics, generally aimed at measuring voltage, current, and resistance. Multimeters are classified by display type into analog multimeters and digital multimeters. They are multifunctional, multi-range measuring instruments. A typical multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels; some can also measure AC current, capacitance, inductance, and certain semiconductor parameters (such as β). A multimeter is a magnetoelectric instrument equipped with a rectifier, capable of measuring various electrical parameters such as AC/DC current, voltage, and resistance. For each electrical quantity, there are generally several ranges. Also known as a multitester or simply multimeter. A multimeter consists of a magnetoelectric ammeter (meter head), measuring circuit, and selector switch. By switching the selector switch, various electrical parameters can be measured conveniently. The main basis for its circuit calculation is Ohm's law for closed circuits. There are many types of multimeters, which should be selected according to different requirements during use.

ELEKTROBOCK electrical component characteristics

(1) offers wide transient response range and strong harmonic measurement capability. The quality of transient characteristics is an important parameter for determining whether a transformer can be applied in power systems, particularly regarding coordination with relay protection operation times. Traditional electromagnetic transformers have poor response characteristics to high-frequency signals due to the presence of an iron core and cannot correctly reflect the transient process on the primary side. In contrast, the frequency range of optoelectronic transformers is mainly determined by the electronic circuit section, without iron core saturation issues, thus accurately reflecting the transient process on the primary side. The structure of optoelectronic sensors allows measurement of harmonics on high-voltage power lines, which is difficult for electromagnetic induction transformers to achieve. (2) Digital interface with strong communication capability: Since optoelectronic sensors transmit optical digital signals, they interface easily with communication networks, and there is no measurement error during transmission. Meanwhile, with the widespread adoption of microcomputer-based protection and control equipment, optoelectronic transformers can directly provide digital quantities to secondary equipment, thereby eliminating the converters and A/D sampling sections in original protection devices, greatly simplifying secondary equipment and promoting research into new protection principles. (3) Small size, light weight, and easy upgradability meet the requirements for substation miniaturization and compactness. Since optoelectronic sensors rely on sensor heads and electronic circuits for signal acquisition and processing, they are small in size, with weights generally below 1003 kg, making them easy to integrate into AIS or GIS, thereby significantly reducing the footprint of substations and meeting the requirements for substation miniaturization and compactness. Additionally, optoelectronic transformers connect to secondary equipment via a small number of optical fibers, greatly reducing cable trenches and cabling.

ELEKTROBOCK electrical component characteristics

The characteristics of inductors are exactly opposite to those of capacitors; they block AC while allowing DC to pass smoothly. The resistance when a DC signal passes through a coil is simply the wire's own resistance, resulting in a very small voltage drop. When an AC signal passes through a coil, a self-induced electromotive force is generated at both ends of the coil. The direction of this self-induced electromotive force is opposite to that of the applied voltage, hindering the passage of AC. Therefore, the characteristic of an inductor is to pass DC and block AC; the higher the frequency, the greater the coil impedance. Inductors often work together with capacitors in circuits to form LC filters, LC oscillators, etc. Additionally, people utilize the characteristics of inductance to manufacture chokes, transformers, relays, etc. Passing DC: Refers to the inductor presenting a conductive state to DC. If the resistance of the inductor coil is ignored, DC can pass through the inductor 'unimpeded.' For DC, the coil's own resistance has very little hindering effect, so it is often ignored in circuit analysis. Blocking AC: When AC passes through an inductor coil, the inductor impedes the AC. This impedance to AC is the inductive reactance of the coil.

ELEKTROBOCK electrical component types

1. Rotating thermometers are made from a curled bimetallic strip. One end of the bimetallic strip is fixed, and the other is connected to a pointer. Because the two metal strips expand to different degrees, the curling degree of the bimetallic strip varies at different temperatures, causing the pointer to indicate different positions on the dial. The temperature can be determined from the reading on the dial. 2. Semiconductor thermometers differ from metals in their resistance change; as temperature rises, their resistance decreases, and the magnitude of change is significant. Therefore, even small temperature changes cause noticeable resistance changes, resulting in thermometers with high precision, often called thermistors. 3. Thermocouple thermometers consist of two different metals connected to a sensitive voltmeter. At different temperatures, the metal junctions produce different potential differences at the ends of the metals. Since the potential difference is very small, a sensitive voltmeter is required for measurement. The temperature can be determined from the voltmeter reading. 4. Optical pyrometers: When an object's temperature is high enough to emit significant visible light, its temperature can be determined by measuring the amount of thermal radiation. This type of thermometer is an optical pyrometer. It mainly consists of a telescope equipped with a red filter and a circuit containing a small bulb, galvanometer, and variable resistor. Before use, establish the relationship between the filament brightness corresponding to different temperatures and the galvanometer readings. During use, align the telescope with the object to be measured and adjust the resistor until the bulb's brightness matches that of the object. The temperature of the object can then be read from the galvanometer. 5. Liquid crystal thermometers made with different formulations have different phase transition temperatures. During phase transition, their optical properties change, causing the liquid crystal to appear to change color. If liquid crystals with different phase transition temperatures are coated on a sheet of paper, the temperature can be determined by the color change of the liquid crystal. The advantage of this thermometer is easy reading, while the disadvantage is insufficient precision. It is commonly used in ornamental fish tanks to indicate water temperature. 6. Digital thermometers use temperature sensors to convert (temperature) into digital signals, which are then displayed in numerical form via a display (such as LCD, digital tube, LED matrix, etc.). They can quickly and accurately measure the maximum human body temperature. Compared with traditional mercury thermometers, they offer advantages such as convenient digital reading, short measurement time, high measurement precision, memory function, and audible alerts. Especially since digital thermometers do not contain mercury, they are harmless to the human body and the surrounding environment, making them particularly suitable for use in hospitals and homes.
