PRIMO electrical components Germany PRIMO model PRIMO price

PRIMO electrical components are devices for making detachable (active) connections between optical fibers. They precisely align the end faces of two optical fibers to maximize the coupling of light energy from the transmitting fiber into the receiving fiber, while minimizing the impact on the system due to their insertion into the optical link. This is the basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and various performance metrics of optical transmission systems.

PRIMO electrical components structure

The basic structure of a voltage transformer is very similar to that of a transformer; it also has two windings, one called the primary winding and the other called the secondary winding. Both windings are mounted on or wound around the iron core. There is insulation between the two windings and between the windings and the iron core, providing electrical isolation between the two windings and between the windings and the iron core. During operation of the voltage transformer, the primary winding N1 is connected in parallel to the line, and the secondary winding N11 is connected in parallel to instruments or relays. Therefore, when measuring voltage on high-voltage lines, although the primary voltage is very high, the secondary voltage is low, ensuring the safety of operators and instruments.

PRIMO electrical components function

A multimeter can not only be used to measure the resistance of the object under test, but also AC and DC voltages, including DC voltage. Some multimeters can even measure the main parameters of transistors and the capacitance of capacitors. Proficient mastery of multimeter usage is one of the most basic skills in electronic technology. Common multimeters include analog multimeters and digital multimeters. An analog multimeter is a multifunctional measuring instrument with a meter head as the core component, and the measured value is read from the pointer of the meter head. The measured value of a digital multimeter is directly displayed in numerical form on an LCD screen, which is convenient to read, and some models also feature voice prompt functions. A multimeter is an instrument that integrates a voltmeter, ammeter, and ohmmeter using a common meter head. The DC current range of a multimeter is a multi-range DC ammeter. Connecting a shunt resistor in parallel with the meter head expands its current range. The DC voltage range of a multimeter is a multi-range DC voltmeter. Connecting a voltage-dividing resistor in series with the meter head expands its voltage range. Different voltage-dividing resistors result in different ranges. The meter head of a multimeter is a magnetoelectric measuring mechanism, which can only pass DC. Diodes are used to convert AC to DC, thereby enabling the measurement of AC electricity.

PRIMO electrical components role

The starter solenoid switch is a key component of the starter motor, and the design quality of the solenoid switch directly affects the reliability of the starter motor. The starter solenoid switch has two functions: first, to connect the main circuit to rotate the starter motor, and second, to push the drive gear out via the shift fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have corresponding suction force, corresponding stroke, and contacts capable of reliably switching high currents. Additionally, it is required to minimize volume and weight as much as possible. Based on these characteristics, the contact structure of solenoid switches generally adopts a contact form, i.e., the moving contacts are made in bridge or disc shapes to provide larger heat dissipation areas and thermal capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements of corresponding stroke, corresponding suction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly within a brass bushing equipped with a solenoid coil. The moving iron core pull rod is connected to the shift fork and one-way clutch. Under the action of the return spring, the moving iron core remains in the non-operating initial position during normal conditions. During starting, the starter drive gear needs to move forward by approximately 12-21mm. Therefore, when the solenoid switch begins to engage, a large magnetomotive force is required to generate the necessary initial suction force. After engagement, the air gap decreases, and the electromagnetic suction force increases sharply, greatly exceeding the force required to maintain the engaged state. For this reason, the solenoid switch employs two coils (an attraction coil and a holding coil). Initially, both the attraction coil and the holding coil jointly generate electromagnetic suction force. After the switch contacts engage, the attraction coil automatically disengages from the operating state, and the holding coil alone maintains the switch in the engaged state. The holding coil current is relatively small, allowing it to be wound with thinner wire. This reduces the volume of the solenoid switch while achieving reasonable suction force matching. To ensure the reliability of the starter motor, special attention must be paid to the design quality of the solenoid switch.
