IRAZOLA electrical components Germany IRAZOLA model IRAZOLA price

IRAZOLA 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 action of an electric field, the alignment direction of liquid crystal molecules changes, altering the transmittance (modulation) of external light sources to achieve electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals through red, green, and blue color filters, color reproduction in the time and space domains is completed.

IRAZOLA electrical component principle

Circuit breakers generally consist of a contact system, arc extinguishing system, operating mechanism, trip unit, and housing. During a short circuit, the magnetic field generated by the high current overcomes the reaction spring, and the trip unit activates the operating mechanism, causing the switch to trip instantaneously. During overload, the current increases, intensifying heat generation; the bimetallic strip deforms to a certain extent to push the mechanism into action (the higher the current, the shorter the action time). Electronic types use current transformers to collect the current magnitude of each phase and compare it with set values. When the current is abnormal, the microprocessor sends a signal to cause the electronic trip unit to activate the operating mechanism. The function of a circuit breaker is to connect and disconnect load circuits, as well as to interrupt fault circuits, preventing accident escalation and ensuring safe operation. Arc extinguishing is a critical issue for high-voltage circuit breakers. The principle of blowing out and extinguishing arcs mainly involves cooling the arc to weaken thermal ionization. On the other hand, blowing the arc elongates it, strengthening the recombination and diffusion of charged particles, while simultaneously dispersing charged particles in the arc gap to rapidly restore the dielectric insulation strength. Low-voltage circuit breakers, also known as automatic air switches, can be used to connect and disconnect load circuits and to control motors that do not start frequently. Their functions equate to the sum of partial or complete functions of electrical components such as knife switches, overcurrent relays, undervoltage relays, thermal relays, and residual current protective devices. They are important protective appliances in low-voltage distribution networks. Low-voltage circuit breakers have multiple protection functions (overload, short circuit, undervoltage protection, etc.), adjustable action values, high breaking capacity, convenient operation, and safety advantages, so they are widely used. Structure and working principle: Low-voltage circuit breakers consist of an operating mechanism, contacts, protection devices (various trip units), and an arc extinguishing system. The main contacts of a low-voltage circuit breaker are closed manually or via electric closing. After the main contacts close, the free-trip mechanism locks the main contacts in the closed position. The coil of the overcurrent trip unit and the heating element of the thermal trip unit are connected in series with the main circuit, while the coil of the undervoltage trip unit is connected in parallel with the power supply. When a short circuit or severe overload occurs in the circuit, the armature of the overcurrent trip unit attracts, causing the free-trip mechanism to act and the main contacts to disconnect the main circuit. When the circuit is overloaded, the heating element of the thermal trip unit generates heat, causing the bimetallic strip to bend and push the free-trip mechanism into action. When the circuit voltage is too low, the armature of the undervoltage trip unit releases, also causing the free-trip mechanism to act. The shunt trip unit is used for remote control; during normal operation, its coil is de-energized. When remote control is required, pressing the start button energizes the coil.

IRAZOLA electrical component structure

For rubber and plastic power cables, copper cores are preferred for power, lighting, and internal installation of electrical equipment. For large cross-section conductors, compacted stranded cores are recommended. Conductors for fixed installations generally adopt Class 1 or Class 2 conductor structures. Insulation materials generally include four types: natural styrene-butadiene rubber, polyvinyl chloride (PVC), polyethylene, and nitrile-PVC compounds. Heat-resistant power cables use PVC rated for 90 °C. Sheath materials generally include five types: PVC, cold-resistant PVC, ant-termite PVC, black polyethylene, and neoprene rubber. Black polyethylene and neoprene sheathed power cables are suitable for extreme cold resistance and outdoor overhead laying. In environments with external forces, corrosion, or humidity, power cables with rubber or plastic sheaths can be used. Rubber and plastic flexible power cables use copper cores with a flexible structure, consisting of multiple single wires stranded together. Flexible conductors generally adopt Class 5 or Class 6 conductor structures. Insulation materials generally include natural styrene-butadiene rubber, PVC, or soft polyethylene plastic. The cabling lay ratio multiplier is small. The outer protective layer uses cotton yarn braiding to prevent overheating and damage to the insulation layer. To facilitate use and simplify production processes, a three-core balanced structure is adopted, saving production labor hours and improving efficiency. For shielded insulated power cables, tinning of conductor cores is permitted in certain occasions. The surface coverage density of the shielding layer must comply with standards or meet user requirements. The shielding layer should be braided or wrapped with tinned copper wires. If an extruded sheath is added outside the shield, the shield may use soft round copper wire braiding or wrapping. To prevent internal interference between cores or pairs, individual phase shielding structures for each core (or pair) can be produced. General-purpose rubber-sheathed rubber power cables use copper flexible wire strands with a flexible structure; paper wrapping is permitted on the surface of large cross-sections to improve bending performance. Insulation uses natural styrene-butadiene rubber, which has good aging properties. Outdoor product rubber uses neoprene or a neoprene-dominated mixed rubber formula. Mining rubber power cables use copper cores with a flexible structure, consisting of multiple single wires stranded together. Flexible conductors generally adopt Class 5 or Class 10 conductor structures. Insulation materials generally use rubber. The cabling lay ratio multiplier is small. Many products use metal braiding to equalize the electric field and improve the sensitivity display of insulation status. They have thicker outer sheaths and are color-coded underground in mines to help construction personnel understand the different voltage levels of the rubber power cables.

IRAZOLA electrical component features

Among various switches, there is a component with the ability to 'sense' objects approaching it—the displacement sensor. Using the sensitivity of the displacement sensor to approaching objects to control the switching on or off is the purpose of a proximity switch. When an object moves toward the proximity switch and approaches within a certain distance, the displacement sensor 'senses' it, and the switch acts. This distance is usually called the 'detection distance.' Different proximity switches have different detection distances. Sometimes, detected objects move toward the proximity switch one by one at certain time intervals and then leave one by one, repeating continuously. Different proximity switches have different response capabilities to detection objects. This response characteristic is called 'response frequency.'
