sensopart electrical components Germany sensopart models sensopart prices

sensopart electrical components are products whose raw material molecular composition is not altered during factory processing, and can be referred to as components. Components belong to devices that do not require an energy source. They include: resistors, capacitors, and inductors. Circuit-type components include diodes and resistors; connection-type components include connectors, sockets, connecting cables, and printed circuit boards (PCB). Devices are products whose raw material molecular structure is altered during factory production and processing. Devices are divided into active devices and discrete devices. The main characteristic of active devices is that they consume electrical energy and require an external power supply. Discrete devices are divided into bipolar junction transistors, field-effect transistors, thyristors, semiconductor resistors, and capacitors. shi

sensopart electrical component classification

Circuit breakers are classified by number of poles: single-pole, two-pole, three-pole, and four-pole; by installation method: plug-in, fixed, and draw-out.

sensopart electrical component structure

The rated current of the fuse element is not equal to the rated current of the fuse. The rated current of the fuse element is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the fuse element and determined in coordination with the main electrical appliance. The fuse mainly consists of 13 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, dimensions, and shape of the fuse element determine the fusing characteristics. Fuse element materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have a low melting point and fuse easily. Due to their higher resistivity, the cross-sectional dimensions of the fuse element made from these materials are larger, generating more metal vapor during fusing, making them suitable only for fuses with low breaking capacity. High melting point materials, such as copper and silver, have a high melting point and are not easy to fuse. However, due to their lower resistivity, they can be made with smaller cross-sectional dimensions than low melting point fuse elements, generating less metal vapor during fusing, making them suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-shaped and strip-shaped. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various fusing characteristic curves, suitable for the needs of different types of protected objects.

sensopart electrical component parameters

1. Nominal varistor voltage: refers to the voltage value across the varistor when a pulse current of specified duration passes through it. 2. Voltage ratio: refers to the ratio of the voltage value generated by the current in the varistor to the voltage value generated by the current in the varistor. 3. Maximum limiting voltage: the peak voltage across the varistor under the maximum pulse peak current Ip that the varistor can withstand and under the specified waveform. 4. Residual voltage ratio: when the current passing through the varistor is at a certain value, the voltage generated across its terminals is called the residual voltage for that current value. The residual voltage ratio is the ratio of the residual voltage to the nominal voltage. 5. Current handling capacity: Current handling capacity, also known as surge current rating, refers to the maximum pulse current value allowed to pass through the varistor under specified conditions. 6. Leakage current: Leakage current, also known as standby current, refers to the current flowing through the varistor when the varistor is under the specified temperature and maximum DC voltage. 7. Voltage temperature coefficient: refers to the rate of change of the nominal voltage of the varistor within the specified temperature range, i.e., the relative change in voltage across the varistor when the temperature changes while the current passing through the varistor remains constant. 8. Current temperature coefficient: refers to the relative change in the current flowing through the varistor when the temperature changes while the voltage across the varistor remains constant. 9. Voltage nonlinearity coefficient: refers to the ratio of the static resistance value to the dynamic resistance value of the varistor under a given applied voltage. 10. Insulation resistance: refers to the resistance value between the lead wires of the varistor and the insulating surface of the resistor body. 11. Static capacitance: refers to the inherent capacitance of the varistor itself. 12. Rated power: the maximum power at which the varistor operates under specific ambient temperature conditions, causing a change in the varistor voltage. 17. Maximum impulse current: the maximum impulse current that causes a change in the varistor voltage when the varistor is subjected to a specific pulse current impact once or twice.
