hugro electrical components are resettable fuses, known in Japan as permanent fuses. Immediately after interrupting an overload or short-circuit current, the fusible element automatically restores to its original state. The housing is made of austenitic stainless steel, with a beryllium oxide ceramic core embedded in the center. The space between the stainless steel and the ceramic core is filled with glass to seal and secure the ceramic core. The fine pores in the ceramic core are filled with metallic sodium as the fusible element, and the void behind the piston is charged with argon gas to compress the metallic sodium. Under normal operating conditions, current can enter from lead terminal A, pass through the metallic sodium in the fine pores of the ceramic core, conduct to the stainless steel housing, and exit via output terminal B. When a short-circuit current passes through the fuse, it rapidly heats the metallic sodium in the fine pores of the ceramic core, causing it to change from a solid to a high-temperature, high-pressure plasma vapor. The resistivity increases rapidly, thereby strongly limiting the short-circuit current and interrupting it instantaneously. At the end of the interruption, the metallic sodium vapor immediately returns to liquid and solid states, while the argon gas pushes the piston again to compress the metallic sodium, re-establishing the circuit connection.

hugro 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, this can be AC voltage or DC voltage. (2) DC resistance: refers to the DC resistance of the relay coil, which can be measured with a multimeter. (3) Pull-in current: refers to the minimum current required to produce the pull-in action of the relay. For normal use, the applied current must be slightly greater than the pull-in current to ensure stable relay operation. The working voltage applied to the coil should generally not exceed the rated operating voltage; otherwise, excessive current may burn out the coil. (4) Release current: refers to the maximum current at which the relay produces the release action. When the current in the pulled-in state decreases to a certain level, the relay returns to the de-energized released state. This 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. These values determine the magnitude of voltage and current the relay can control. Do not exceed these values during use, as doing so can easily damage the relay contacts.

hugro electrical component functions

Antennas radiate radio waves and also receive radio waves. However, what the transmitter sends to the antenna via the feed line is not radio waves, nor can the receiving antenna directly send radio waves to the receiver via the feed line; an energy conversion process is required. Below, we analyze the signal transmission process using radio communication equipment as an example to illustrate the energy conversion role of antennas. At the transmitting end, the modulated high-frequency oscillating current (energy) generated by the transmitter is input to the transmitting antenna via the feeding device (which may directly transmit current waves or electromagnetic waves depending on frequency and form). The transmitting antenna converts the high-frequency current or guided wave (energy) into radio waves—free electromagnetic waves (energy)—radiating them into the surrounding space. At the receiving end, radio waves (energy) are converted by the receiving antenna into high-frequency current or guided wave (energy), which is transmitted to the receiver via the feeding device. From this process, it is evident that the antenna is not only a device for radiating and receiving radio waves but also an energy converter, serving as the interface component between the circuit and space.
