qantek electrical components Germany qantek model qantek price

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

qantek electrical component characteristics

The static characteristics of a sensor refer to the relationship between the output quantity and the input quantity of the sensor for static input signals. Since the input and output quantities are independent of time at this point, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input quantity as the abscissa and the corresponding output quantity as the ordinate. The main parameters characterizing the static characteristics of a sensor include: linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: Refers to the degree to which the actual relationship curve between the sensor output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted straight line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of the static characteristics of a sensor. It is defined as the ratio of the increment in the output quantity to the corresponding increment in the input quantity that causes this increment. Use S to represent sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide during the change of the input quantity from small to large (forward stroke) and from large to small (reverse stroke). For the same magnitude of input signal, the output signal magnitudes for the forward and reverse strokes of the sensor are not equal; this difference is called the hysteresis difference. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor input quantity undergoes continuous multiple full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor output changes over time while the input remains constant. There are two reasons for drift: one is the sensor's own structural parameters; the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor input increases slowly from a non-zero value, after exceeding a certain increment, the output undergoes an observable change; this input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor input increases slowly from zero, after reaching a certain value, the output undergoes an observable change; this input value is called the sensor's threshold voltage.

Commonly used circuits include RC phase-shifting bridge trigger circuits, unijunction transistor trigger circuits, bipolar junction transistor trigger circuits, and trigger circuits using small thyristors to trigger large thyristors, etc. The main parameters of thyristors are: 1, rated on-state average current IT Under certain conditions, the average value of the 50 Hz sinusoidal half-wave current that can continuously flow between the anode and cathode. 2, forward blocking peak voltage VPF With the gate open and no trigger signal applied, and before the anode forward voltage exceeds the conduction voltage, the forward peak voltage that can be repeatedly applied across the thyristor. The forward peak voltage withstandable by the thyristor must not exceed this parameter value given in the manual. 3, reverse blocking peak voltage VPR When a reverse voltage is applied to the thyristor and it is in the reverse off-state, the reverse peak voltage that can be repeatedly applied across the thyristor. During use, this parameter value given in the manual must not be exceeded. 4, trigger voltage VGT At a specified ambient temperature, when a certain voltage is applied between the anode and cathode, the minimum gate current and voltage required for the thyristor to switch from the off-state to the on-state. 8, holding current IH At a specified temperature, with the gate circuit open, the minimum anode forward current required to maintain the thyristor in the on-state. Many new types of thyristor components have been introduced, such as fast thyristors suitable for high-frequency applications, bidirectional thyristors that can be controlled to conduct in both directions using positive or negative trigger signals, and thyristors that can be turned on by a positive trigger signal and turned off by a negative trigger signal, etc.

qantek electrical component principles

A diesel engine drives the generator to operate, converting the energy of diesel into electrical energy. Inside the diesel engine cylinder, clean air filtered through the air filter mixes thoroughly with high-pressure atomized diesel injected from the nozzle. Under the compression of the upward-moving piston, the volume decreases, and the temperature rises rapidly, reaching the ignition point of diesel. The diesel ignites, the mixed gas burns violently, the volume expands rapidly, pushing the piston downward, which is called "work". A gasoline engine drives the generator to operate, converting the energy of gasoline into electrical energy. Inside the gasoline engine cylinder, the mixed gas burns violently, the volume expands rapidly, pushing the piston downward to perform work. Whether it is a diesel generator or a gasoline generator, each cylinder performs work sequentially in a certain order. The thrust acting on the piston is converted into force driving the crankshaft rotation via the connecting rod, thereby rotating the crankshaft. By installing a brushless synchronous AC generator coaxially with the power machine crankshaft, the rotation of the power machine can drive the rotor of the generator. Using the principle of 'electromagnetic induction', the generator outputs induced electromotive force, generating current through a closed load circuit.
