Process Parameter electrical components German Process Parameter models Process Parameter prices

Process Parameter electrical components are active-matrix liquid crystal displays driven by thin-film transistors. They primarily use current to stimulate liquid crystal molecules to generate points, lines, and planes, which combine with backlights to form images. IPS, TFT, and SLCD are all subclasses of LCD. Their operating principle is that, under the influence of an electric field, the alignment of liquid crystal molecules changes, altering the transmittance (modulation) of external light sources to complete electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals, color reproduction in the time and spatial domains is completed through red, green, and blue primary color filter films.

Process Parameter electrical component parameters

(1) Rated operating voltage: refers to the voltage required by the coil for the relay to operate normally. Depending on the relay model, it can be AC voltage or DC voltage. (2) DC resistance: refers to the DC resistance of the coil in the relay, which can be measured with a multimeter. (3) Pull-in current: refers to the minimum current required for the relay to perform the pull-in action. During normal use, the supplied current must be slightly greater than the pull-in current so that the relay can operate stably. For the operating voltage applied to the coil, generally do not exceed the rated operating voltage; otherwise, excessive current will burn out the coil. (4) Release current: refers to the maximum current at which the relay performs the release action. When the current in the pulled-in state of the relay decreases to a certain level, the relay returns to the de-energized released state, at which point the current is much lower than the pull-in current. (5) Contact switching voltage and current: refer to the voltage and current that the relay is allowed to handle. It determines the magnitude of voltage and current that the relay can control. Do not exceed these values during use; otherwise, the relay contacts are easily damaged.

Process Parameter electrical component characteristics

Operating characteristics: The main characteristics characterizing the performance of a synchronous generator are the no-load characteristic and the load operating characteristic. These characteristics are important bases for users to select generators. No-load characteristic: When the generator is not connected to a load, the armature current is zero, which is called no-load operation. Armature reaction: When the generator is connected to a symmetrical load, the three-phase currents in the armature windings produce another rotating magnetic field, called the armature reaction magnetic field. Its speed is exactly equal to the rotor speed, and both rotate synchronously. The armature reaction magnetic field of a synchronous generator and the rotor excitation magnetic field can both be approximately considered to be distributed according to a sinusoidal law. The spatial phase difference between them depends on the time phase difference between the no-load electromotive force E3 and the armature current I. The armature reaction magnetic field is also related to the load condition. When the generator load is inductive, the armature reaction magnetic field has a demagnetizing effect, causing the generator voltage to decrease; when the load is capacitive, the armature reaction magnetic field has a magnetizing effect, causing the generator output voltage to increase. Load operating characteristics: Mainly refer to the external characteristic and the adjustment characteristic. The external characteristic is the relationship between the generator terminal voltage U and the load current I when the speed is at the rated value, and the excitation current and load power factor are constant. The adjustment characteristic is the relationship between the excitation current If and the load current I when the speed and terminal voltage are at rated values, and the load power factor is constant.
