What is the understanding of loop power supply? What does circuit loop mean?

Loop power supply understanding: that is, closed loop power supply, each loop must be closed to be effective. To put it simply, a circuit is a connected circuit, and the electrons in the circuit must start from the positive electrode and pass through the entire circuit.

Loops are a fundamental concept of physical electricity. It generally refers to the current path composed of power supply, electric keys, electrical appliances, etc. A single circuit refers to a circuit in which a load has a power supply; A double circuit is a circuit in which one load has two power supplies.

The line that supplies power to the substation is called the power supply circuit. The distribution station then sends power to each workshop, which is called the distribution circuit. The control loop, simply put, is a circuit that allows the machine tool to move and stop.

1. The circuit power supply can be one of multiple circuits, whether there is a distribution switchboard or a multi-transmitter, multi-isolator configuration after the difference between the name.

2 power supply is a requirement and "action", 24V is a specific reference, in fact, the switching power supply generally needs 220V AC power supply, the distribution single circuit can also be called the circuit power supply, or the instrument only has AC DC power supply configuration called its own DC circuit power supply.

Double-circuit power supply refers to two substations or two lines of the same voltage from two substations or two substations. When one line fails and the power goes out, the other line can be switched over and put into use immediately. It is mostly used in schools, enterprises and institutions, which is convenient and fast.

My understanding is that the 24V DC power supply is the internal power supply of the equipment, while the loop power supply is the AC power supply 220V or 380V power supply.

That is, closed loops, each loop must be closed to be effective.

To put it simply, a circuit is a connected circuit, the current in a circuit must start from the positive pole through the entire circuit, of course, there must be resistance in the circuit, otherwise a short circuit will be formed, and a closed circuit will be formed after all electrical appliances return to the negative pole.

What is a loop is a live wire, and a neutral wire forms a closed circuit.

The two ends of the power supply are directly connected by wires without passing through any electrical equipment, which is called a short circuit. In the event of a short circuit, a very large current will occur in the circuit, which is called a short circuit current. When a short circuit occurs in a circuit, the short-circuit current can increase to far exceed the allowable current limit of the wire, causing the wire to heat up violently and even burn the electrical equipment.

"Independent loop" is a concept commonly used when writing equations for column loop circuits.

For each independent loop defined, there must be, at least one unused branch, until all the branches have been used, so that the equations written in the column are guaranteed to be independent and the unknown quantity can be solved simultaneously.

For example, a circuit with a zigzag structure has three circuits, but only two independent circuits.

These two independent circuits can be two small "mouth" glyph circuits, or one small "mouth" glyph plus the outermost closed circuit.

Another set of independent circuits" in a circuit, which can be understood as "another independent circuit".

The primary circuit is a single-branch circuit, but an independent circuit is not necessarily a primary circuit.

The primary loop must be an independent loop, but an independent loop is not necessarily a primary loop.

For a given tree, when a conjunction, a loop is formed, and this loop is composed of tree branches except for the added branches. Such a circuit is called a basic circuit, also known as a single-branch circuit.

A loop is when the current goes from the positive pole of the circuit to the negative pole, creating a potential difference.

If there is no such circuit, the circuit will be incomplete and will not be able to work normally. The other circuit must be closed, otherwise no current will be generated.

An electrician is a person (type of work) engaged in industrial production systems such as electricity production and electrical manufacturing, electrical maintenance, and construction and installation industries. A person who is engaged in the study of objective laws and their applications in the field of electromagnetism is usually called an electrical engineer. Electrical engineering, a discipline, as opposed to electronics, focuses on the study of strong electricity.

It can also be short for electrical engineering. There are five levels of electricians. The skill appraisal is:

Elementary Skills (Level 5 Qualification), Intermediate Skills (Level 4 Qualification), Advanced Skills (Level 3 Qualification), Technician (Level 2 Qualification), Senior Technician (Level 1 Qualification). Professional qualifications belong to the technical level, not to the professional title, but the state recognizes that the two are treated the same (salary, housing, hukou, etc.), and the level 3 qualification (advanced skills) is equivalent to that of an assistant engineer.

Level 2 qualification (technician) corresponds to engineers, and level 1 qualification (senior technician) corresponds to senior engineers. Professional titles are divided into: technician (junior title), assistant engineer (junior title), engineer (intermediate title).

Senior Engineer (Deputy Senior Title.

Professor-level engineer (senior title), researcher-level engineer (the same senior title as professor-level engineer).
