Jean Mueller electrical components refer to switching devices capable of closing, carrying, and breaking current under normal circuit conditions, and closing, carrying, and breaking current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage and low-voltage types based on their application range; the boundary between high and low voltage is somewhat ambiguous, but generally, equipment above 3kV is referred to as high-voltage apparatus. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When severe faults such as overload, short circuit, or undervoltage occur, they can automatically disconnect the circuit. Their function is equivalent to a combination of fuse-switches and over/under thermal relays. Moreover, component replacement is generally not required after interrupting fault currents. They have been widely applied. In the generation, transmission, and use of electricity, power distribution is an extremely important link. Distribution systems include transformers and various high- and low-voltage electrical equipment, with low-voltage circuit breakers being a widely used type of electrical apparatus.

Jean Mueller electrical component principles

A transformer is a device that changes AC voltage using the principle of electromagnetic induction. Its main components are the primary coil, secondary coil, and iron core (magnetic core). In electrical equipment and wireless circuits, it is commonly used for stepping voltage up or down, impedance matching, and safety isolation. In generators, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electromotive force is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux linking the coil varies; this is the principle of mutual induction. A transformer is a device that utilizes electromagnetic mutual induction to transform voltage, current, and impedance.

Optical measurement and control systems are diverse, developed based on different principles of how luminous flux acts on photoelectric elements. According to the nature of the output from the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, which has a single-valued relationship with the measured quantity. Based on the method of measuring the target object, analog photoelectric sensors can be classified into three major types: transmission (absorption) type, diffuse reflection type, and light-blocking (beam interruption) type. The transmission type refers to placing the measured object in the optical path; the light energy emitted by a constant light source passes through the measured object, and after partial absorption, the transmitted light is projected onto the photoelectric element. The diffuse reflection type refers to projecting light from a constant light source onto the measured object, which then reflects off the surface of the object and is projected onto the photoelectric element. The light-blocking type refers to when part of the luminous flux emitted by the light source is blocked by the measured object, causing a change in the luminous flux projected onto the photoelectric element; the degree of change depends on the position of the measured object within the optical path. Photodiodes are the most common type of light sensor. A photodiode resembles a standard diode in appearance. When there is no illumination, it behaves like a ordinary diode with very small reverse current, known as the dark current of the photodiode. When illuminated, carriers are excited, generating electron-hole pairs, referred to as photo-generated carriers. Under the influence of an external electric field, these photo-generated carriers participate in conduction, forming a reverse current much larger than the dark current; this reverse current is called photocurrent. The magnitude of the photocurrent is proportional to the light intensity, allowing an electrical signal that varies with light intensity to be obtained across the load resistor.
