swissbit electrical components refer to lightning arresters or antenna switching tubes used for overvoltage protection, which contain two or more electrodes and are filled with a certain amount of inert gas. A gas discharge tube is a gap-type lightning protection component used in the lightning protection of communication systems. Gas discharge tubes are gap-type lightning protection components that have been widely applied in the lightning protection of communication systems. Discharge tubes are commonly used in the first or first two stages of multi-stage protection circuits to discharge instantaneous lightning overcurrents and limit overvoltages. Due to the very high inter-electrode insulation resistance and very small parasitic capacitance of the discharge tube, it has clear advantages for lightning protection of high-frequency signal lines. The main disadvantages of the discharge tube's protection characteristics are its large discharge delay and less-than-ideal operating sensitivity, making it difficult to effectively suppress lightning waves with a steep wavefront rise. There is also a follow-current issue in the lightning protection of power systems. Commonly used gas discharge tubes include two-electrode and three-electrode discharge tubes. Their encapsulation housing material is mostly ceramic, hence they are called ceramic discharge tubes.

swissbit electrical component function

The main purposes of disconnect switches (knife switches) are: 1, to isolate the power supply, disconnecting high-voltage maintenance equipment from live equipment, creating a clearly visible break point between them. 2, disconnect switches cooperate with circuit breakers to perform switching operations according to system operation requirements, thereby changing the system wiring configuration. 3, to connect or disconnect low-current circuits. Disconnect switches can perform the following operations: connect or disconnect bypass currents of loop switches; connect or disconnect grounding wires at transformer neutral points, but if an arc-suppression coil is connected to the neutral point, operation is only permitted when the system is fault-free; connect or disconnect voltage transformers and lightning arresters; connect or disconnect capacitive currents of busbars and equipment directly connected to the busbars; connect or disconnect no-load lines with capacitive currents not exceeding 5 amperes; triple-pole disconnect switches can connect or disconnect loads with voltages at or below 10 kilovolts and currents below 17 amperes. When operating disconnect switches, note that when energizing a line, close the busbar-side disconnect switch first, then the line-side disconnect switch, and finally the circuit breaker. When de-energizing a line, open the circuit breaker first, then open the disconnect switches. Do not operate high-voltage disconnect switches under load.

swissbit electrical component principle

The forward characteristic of the volt-ampere curve of a Zener diode is similar to that of a standard diode. In the reverse characteristic, when the reverse voltage is below the reverse breakdown voltage, the reverse resistance is very high and the reverse leakage current is extremely small. However, when the reverse voltage approaches the critical value of the reverse voltage, the reverse current increases suddenly, known as breakdown. At this critical breakdown point, the reverse resistance drops suddenly to a very small value. Although the current varies over a wide range, the voltage across the diode remains basically stable near the breakdown voltage, thereby achieving the voltage regulation function of the diode.

swissbit electrical component principle

A fuel cell is an energy conversion device that converts the chemical energy stored in fuel and oxidant directly into electrical energy isothermally according to electrochemical principles, i.e., the working principle of a primary battery. Thus, the actual process is an oxidation-reduction reaction. A fuel cell mainly consists of four parts: the anode, cathode, electrolyte, and external circuit. Fuel gas and oxidant gas are introduced into the anode and cathode of the fuel cell, respectively. The fuel gas releases electrons at the anode; the electrons are conducted through the external circuit to the cathode, where they combine with the oxidant gas to form ions. Under the action of the electric field, the ions migrate through the electrolyte to the anode, react with the fuel gas, complete the circuit, and generate current. Meanwhile, due to the electrochemical reaction itself and the internal resistance of the battery, the fuel cell also generates a certain amount of heat. In addition to conducting electrons, the cathode and anode also serve as catalysts for the oxidation-reduction reaction. When the fuel is a hydrocarbon, the anode requires higher catalytic activity. The cathode and anode are typically porous structures to facilitate the introduction of reactant gases and the removal of products. The electrolyte serves to transport ions and separate the fuel gas from the oxidant gas. To prevent mixing of the two gases, which would cause a short circuit within the battery, the electrolyte is typically a dense structure. The composition of a fuel cell is the same as that of a general battery. Its single cell consists of positive and negative electrodes (the negative electrode is the fuel electrode and the positive electrode is the oxidant electrode) and an electrolyte. The difference is that the active materials of a general battery are stored inside the battery, thus limiting the battery capacity. In contrast, the positive and negative electrodes of a fuel cell do not contain active materials themselves but are merely catalytic conversion elements. Therefore, a fuel cell is truly an energy conversion machine that converts chemical energy into electrical energy. During battery operation, fuel and oxidant are supplied externally to undergo reaction. In principle, as long as reactants are continuously input and reaction products are continuously removed, the fuel cell can generate electricity continuously.
