ASSAABLOY electrical components Germany ASSAABLOY model ASSAABLOY price

ASSAABLOY electrical components are a type of transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the reverse conversion. It is a component in radio equipment used to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, all rely on antennas for operation. In addition, for energy transmission using electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas possess reciprocity, meaning the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna for transmission or reception are identical. This is the reciprocity theorem of antennas. As we know, radio equipment such as communication, radar, navigation, broadcasting, and television devices transmit information via radio waves and require the radiation and reception of radio waves. In radio equipment, the device used to radiate and receive radio waves is called an antenna. The antenna provides the necessary coupling between the transmitter or receiver and the medium through which radio waves propagate. Like transmitters and receivers, the antenna is also an important component of radio equipment.

ASSAABLOY electrical component performance

1. Protection characteristics: When the impact strength of the surge source does not exceed the specified value, the clamping voltage of the varistor must not exceed the impulse withstand voltage that the protected object can endure. 2. Surge withstand characteristics: The varistor itself must be able to withstand the specified surge current, surge energy, and the average power when multiple surges occur sequentially. 3. Life characteristics include two aspects: first, continuous operating voltage life, meaning the varistor should reliably operate for a specified time (in hours) under specified ambient temperature and system voltage conditions; second, surge life, meaning it can reliably withstand a specified number of surges. 7. After the varistor is integrated into the system, in addition to its "safety valve" protection role, it introduces some additional effects, known as "secondary effects," which should not degrade the normal operating performance of the system. The main factors to consider at this stage are three: first, the inherent capacitance of the varistor; second, the leakage current under system voltage; and third, the influence on other circuits caused by the coupling of the varistor's nonlinear current through the source impedance.

ASSAABLOY electrical component classification

Based on the working power supply of the motor, it can be divided into DC motors and AC motors. Among them, AC motors are further divided into single-phase motors and three-phase motors. Motors can be classified into DC motors, asynchronous motors, and synchronous motors based on their structure and working principle. Synchronous motors can be further divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, etc. Phase asynchronous motors and shaded-pole asynchronous motors, etc. AC commutator motors are further divided into single-phase series-wound motors, AC/DC universal motors, and repulsion motors. Motors can be classified into capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors based on their starting and running methods. Motors can be classified into drive motors and control motors based on their application. Drive motors are further divided into motors for power tools, motors for home appliances, and motors for other general small mechanical equipment. Control motors are further divided into stepper motors and servo motors, etc. Motors can be classified into squirrel-cage induction motors and wound-rotor induction motors based on the rotor structure. Motors can be classified into high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors based on their operating speed.

ASSAABLOY electrical component classification

Thyristors have various classification methods: (1) Classification by turn-off, turn-on, and control methods: Thyristors can be divided into conventional thyristors, bidirectional thyristors, reverse-conducting thyristors, gate-turn-off thyristors, BTG thyristors, temperature-controlled thyristors, and light-controlled thyristors, among others. (2) Classification by pins and polarity: Thyristors can be divided into two-pin thyristors, three-pin thyristors, and four-pin thyristors based on their pins and polarity. (3) Classification by package type: Thyristors can be divided into three types based on their package form: metal-packaged thyristors, plastic-packaged thyristors, and ceramic-packaged thyristors. Among them, metal-packaged thyristors are further divided into bolt-type, flat-type, and round-case types, among others; plastic-packaged thyristors are divided into two types: with heat sink and without heat sink. (4) Classification by current capacity: Thyristors can be divided into three types based on current capacity: high-power thyristors, medium-power thyristors, and low-power thyristors. Typically, high-power thyristors mostly use metal case packaging, while medium and low-power thyristors mostly use plastic or ceramic packaging. (5) Classification by turn-off speed: Thyristors can be divided into conventional thyristors and high-frequency (fast) thyristors based on their turn-off speed. (6) Zero-crossing triggering - generally for power regulation, i.e., triggering occurs when the phase of the sinusoidal AC voltage crosses zero; triggering must occur at the zero-crossing point to turn on the thyristor. (7) Non-zero-crossing triggering - the thyristor can be triggered and turned on regardless of the phase of the AC voltage; common is phase-shift triggering, i.e., changing the output percentage by altering the conduction angle (phase angle) of the sinusoidal AC voltage.
