aries electrical components are indispensable measuring instruments for departments such as power electronics, generally with the main purpose of measuring voltage, current, and resistance. Multimeters are divided into analog multimeters and digital multimeters according to the display method. It is a multi-function, multi-range measuring instrument. General multimeters can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels, etc. Some can also measure AC current, capacitance, inductance, and some semiconductor parameters (such as β), etc. A multimeter is a magnetoelectric instrument with a rectifier that can measure various electrical parameters such as AC/DC current, voltage, and resistance. For each electrical quantity, there are generally several ranges. Also known as a multi-meter or simply multi-meter. A multimeter consists of a magnetoelectric ammeter (meter head), measuring circuit, and selector switch, etc. Through the switching of 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, and they should be selected according to different requirements during use.

aries electrical component principle

In the lines for power generation, transformation, transmission, distribution, and consumption, the current magnitude varies significantly, ranging from a few amperes to tens of thousands of amperes. To facilitate measurement, protection, and control, it needs to be converted to a relatively uniform current. Additionally, the voltage on the lines is generally high, making direct measurement very dangerous. Current transformers serve the role of current transformation and electrical isolation. For analog ammeters, the secondary current of current transformers is mostly at the ampere level. For digital instruments, the sampled signal is generally at the milliampere level. The secondary current of miniature current transformers is at the milliampere level, mainly serving as a bridge between large transformers and sampling. Miniature current transformers are also referred to as "instrument current transformers." ("Instrument current transformer" implies precision current transformers with multiple current ratios used in laboratories, generally for expanding instrument ranges.) Similar to transformers, current transformers operate based on the principle of electromagnetic induction; transformers transform voltage, while current transformers transform current. The winding of the current transformer connected to the measured current is called the primary winding; the winding connected to the measuring instrument is called the secondary winding. The ratio of the primary winding current I1 to the secondary winding I6 current is called the actual current ratio K. The current ratio when the current transformer operates at rated current is called the rated current ratio of the current transformer, denoted by Kn.

aries electrical component applications

The structure and characteristics of Schottky diodes make them suitable for high-frequency rectification in low-voltage, high-current output applications. They are used for detection and mixing at very high frequencies (such as X band, C band, S band, and Ku band) and as clamps in high-speed logic circuits. In addition to the characteristic parameters of ordinary PN junction diodes, the electrical parameters of Schottky diodes used for detection and mixing include intermediate frequency impedance, voltage standing wave ratio, and noise figure, etc. Schottky barrier diodes are a type of low-power, ultra-high-speed semiconductor device. The most significant feature is the extremely short reverse recovery time (which can be as small as a few nanoseconds). They are mostly used as high-frequency, low-voltage, high-current rectifier diodes, freewheeling diodes, and protection diodes. They are also used as rectifier diodes and small-signal detection diodes in circuits such as microwave communications. They are relatively common in communication power supplies, variable frequency drives, etc. A typical application is in the switching circuit of bipolar junction transistors BJT, where connecting a Shockley diode to the BJT clamps it, so that the transistor is actually close to the cutoff state when in the conduction state, thereby improving the switching speed of the transistor. The main feature of Schottky diodes is the smaller forward voltage drop. At the same current, its forward voltage drop is much smaller. Additionally, its recovery time is short. It also has some disadvantages: lower voltage resistance and slightly larger leakage current. These factors must be considered comprehensively when selecting.

aries electrical component structure

Some gas discharge tubes use glass as the tube encapsulation shell, while others use ceramic as the encapsulation shell. The discharge tube is filled with inert gases with stable electrical properties (such as argon and neon, etc.). Common discharge tubes generally have two or three discharge electrodes, separated by inert gas. According to the number of electrodes, discharge tubes can be divided into two-electrode and three-electrode discharge tubes. Ceramic two-electrode discharge tubes consist of main components such as pure iron electrodes, nickel-chromium-cobalt alloy caps, silver-copper welding caps, and ceramic tube bodies. Radioactive oxides are coated on the discharge electrodes inside the tube, and radioactive elements are also coated on the inner wall of the tube body to improve discharge characteristics. Discharge electrodes mainly have two structures: rod-shaped and cup-shaped. In discharge tubes with rod-shaped electrodes, a cylindrical heat shield is installed between the electrode and the tube wall. This heat shield ensures uniform heating of the ceramic tube body, preventing local overheating that could cause tube fracture. Radioactive oxides are also coated inside the heat shield to further reduce discharge dispersion. In discharge tubes with cup-shaped electrodes, a molybdenum mesh is installed at the cup opening, and cesium element is installed inside the cup, also to reduce discharge dispersion. Three-electrode discharge tubes are also composed of components such as pure iron electrodes, nickel-chromium-cobalt alloy caps, silver-copper welding caps, and ceramic tube bodies. Unlike two-electrode discharge tubes, three-electrode discharge tubes add a nickel-chromium-cobalt alloy cylinder as the third electrode, i.e., the ground electrode.
