Question 1: What are the national power equipment? Electric power equipment is nothing more than the upstream and downstream equipment of the power transmission substation. Do you want to be an agent or run a business?

Question 2: What is the difference between electric equipment and electric materials? As the name suggests, the literal meaning of equipment generally refers to equipment and materials. The literal meaning of materials is items and materials. One is electrical appliances and materials, and the other is electrical items and materials. There is no essential difference, just different expressions.

Question 3: Classification of electrical equipment. What are the classifications of electrical equipment? There are many electrical equipment in the power system. According to their different roles in operation, they are usually divided into electrical primary equipment and electrical secondary equipment. .

Electrical primary equipment:

Equipment that directly participates in the production, transformation, transmission, distribution and consumption of electrical energy is called electrical primary equipment. It mainly includes:

Electrical energy processing Production and transformation equipment, such as generators, motors, transformers, etc.;

Switching appliances that connect and disconnect circuits, such as circuit breakers, isolating switches, contactors, fuses, etc.

Current-carrying conductors and gas-insulated equipment, such as busbars, power cables, insulators, wall bushings, etc.

Equipment that limits overcurrent or overvoltage, such as current-limiting reactors, lightning arresters, etc.

Transformer equipment: reducing high voltage and high current in the primary circuit for use by measuring instruments and relay protection devices, such as voltage transformers and current transformers

Secondary power equipment

In order to protect and ensure the normal operation of electrical primary equipment, equipment that measures, monitors, controls and regulates its operating status is called electrical secondary equipment. Mainly include various measuring meters, various relay protection and automatic devices, DC power equipment, etc.

Question 4: What are the electrical equipment? Well, there are a lot of nails and a lot of equipment. Electric power equipment is divided into primary equipment and secondary equipment. Primary equipment refers to primary circuit equipment with large currents, such as generators, transformers, circuit breakers, transformers, etc. Secondary equipment refers to secondary circuit equipment with small operating currents, such as voltmeters and ammeters. Circuit breaker measuring equipment and so on. . . .

Question 5: Electrical equipment. What does electric equipment include? There are many, many, many electric fittings in Changhong, Shanxi. . . . . .

Question 6: What are the list of power equipment stocks?
