EFFEKTA electrical components Germany EFFEKTA model EFFEKTA price

EFFEKTA electrical components are chemical devices that directly convert the chemical energy of fuel into electrical energy, also known as electrochemical generators. They are the fourth power generation technology after hydropower, thermal power, and nuclear power. Since fuel cells convert part of the Gibbs free energy in the chemical energy of fuel into electrical energy through electrochemical reactions, they are not limited by the Carnot cycle effect, resulting in high efficiency; in addition, fuel cells use fuel and oxygen as raw materials and have no mechanical transmission parts, so they emit very few harmful gases and have a long service life. It can be seen that, from the perspective of energy conservation and ecological environment protection, fuel cells are the most promising power generation technology. A power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through electrochemical reactions. Fuel cells can theoretically operate at a thermal efficiency close to 100%, offering high economic efficiency. Currently, due to various technical limitations and considering the energy consumption of the entire system, the total conversion efficiency of various practically operating fuel cells is mostly in the range of 45% to 60%; if waste heat utilization is considered, it can reach over 80%. In addition, fuel cell devices contain no or very few moving parts, operate reliably, require less maintenance, and are quieter than traditional generator sets. Furthermore, the electrochemical reaction is clean and complete, producing very few harmful substances. All these factors make fuel cells regarded as a very promising energy power device. A fuel cell is an electrochemical power generation device that converts chemical energy directly into electrical energy isothermally via electrochemical methods without going through a heat engine process, is not limited by the Carnot cycle, and thus has high energy conversion efficiency and no pollution, becoming an ideal way of energy utilization. At the same time, with the continuous maturity of fuel cell technology and the sufficient natural gas supply provided by the West-East Gas Pipeline Project, the commercial application of fuel cells has broad development prospects.

EFFEKTA electrical component principle

Generators can convert mechanical energy into electrical energy, and dry cells can convert chemical energy into electrical energy. Generators and batteries themselves are not charged; their two poles have positive and negative charges respectively, generating voltage (current is formed by the directional movement of charges under the action of voltage). Charges already exist in conductors; to generate current, only voltage needs to be applied. When conductors are connected to the two poles of a battery, positive and negative charges are released to generate current. When the charges are exhausted, the current (and voltage) disappears. Dry cells and the like are called power sources. A device that converts alternating current into direct current through transformers and rectifiers is called a rectified power supply. Electronic devices that can provide signals are called signal sources. Crystal transistors can amplify the signal sent from the previous stage and transmit the amplified signal to the subsequent circuit. For the subsequent circuit, the crystal transistor can also be regarded as a signal source. Rectified power supplies and signal sources are sometimes also called power sources.

EFFEKTA electrical component characteristics

Under normal circumstances, the actual static characteristic output of a sensor is a curve rather than a straight line. In practical work, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximately represent the actual characteristic curve. Linearity (non-linear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero input and full-scale output points is used as the fitted straight line; or the theoretical straight line with the minimum sum of squared deviations from each point on the characteristic curve is used as the fitted straight line, which is called the least squares fitted straight line.

EFFEKTA electrical component structure

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, with the thermoelectric potentials output by each thermocouple superimposing on each other. Used to measure small temperature differences or average temperatures. Structure of a thermopile: the radiation receiving surface is divided into several sections, each connected to a thermocouple, and connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made into wire-type and thin-film types, as well as multi-channel and array-type devices.
