What part of an electrical tool is not allowed to be carried when using it?

When using electrical tools, do not lift the wires or rotating parts of the electrical tools. When using electrical tools on ladders, safety measures should be taken to prevent electric shock from falling. When working with electrical tools, if you leave the workplace or temporarily stop working for any reason, or encounter a temporary power outage, you must immediately cut off the power supply.

Electrical Engineering (English: Electrical Engineering), referred to as EE, is a core discipline and key discipline in the field of modern science and technology.

Traditionally electrical engineering is defined as the sum of related disciplines used to create electrical and electronic systems. This definition was originally very broad, but with the rapid development of science and technology, the current concept of electrical engineering has far exceeded the scope of the above definition. A professor at Stanford University pointed out: "Today's electrical engineering covers almost all engineering behaviors related to electronics and photons."

It is the great progress of electronic technology that has promoted the arrival of the information age based on computer networks and changed all aspects including human life and work patterns. The electrical engineering discipline of American University, also known as the Department of Electrical Engineering, the Department of Electrical Engineering and Information Science, the Department of Electrical Engineering and Computer Science, etc., mainly focuses on computer and information technology as its research direction and focus.

Extended information:

1. Electrical installation part

Electrical installation mainly refers to: equipment and services in power transformation and distribution stations Ground-dispersed power and lighting distribution boxes.

Such as: dry-type power transformers, complete sets of high-voltage and low-voltage distribution cabinets, DC cabinets for control operation (with batteries), backup uninterruptible power supply cabinets, lighting distribution boxes, power distribution boxes (cabinets), power Factor capacitor compensation cabinet and backup diesel generator set, etc.

Its characteristics are: a combination of independent functional electrical components, the rated voltage is mostly 10KV or 380V/220V, only the voltage in the control system is 24V or 12V.

2. Cabling system part

The wiring system consists of: wires, cables and busbars; a combination of fixed components (for wires, cables and busbars) and protection components (for wires, cables and busbars) ;

Function of wiring system: Mainly plays the role of transmitting power.

Most of the wiring systems in building electrical engineering have rated voltages of 380V/220V.

3. Electrical part of electrical equipment

The electrical part of electrical equipment: mainly refers to the electric drive, electric heating, electric lighting, etc. that are matched with other building equipment to directly consume electric energy and convert it into other The part that can.

Such as: dedicated or converted power supplies for motors and electric heaters and their start-up control equipment, lighting and decorative lamps and switches and sockets, communications, film and television and intelligent engineering, as well as special DC power supplies for environmentally friendly dust removal and kitchen fume removal. wait.
