Information
When we were working as an electrician, there were several common electrical tools:
Wire pliers, pointed nose pliers, round nose pliers, screwdriver, electrician knife, adjustable wrench, test pencil and bolt, tongs, clamp, etc. The meter is divided into ammeter, voltmeter, meter and multimeter.
Here are just a few simple electrical tools.
The screwdriver
The most commonly used electrical tools, consisting of a tool head and a handle. The shape of the knife has a zigzag shape and a cruciform, which is used to screw the head of the head for the transverse groove or the cruciform slot. The specification of a screwdriver refers to the length of a metal rod, which is 75, 100, 125, 150 mm. When used, hold the handle firmly and press the knife firmly against the screw, rotate it clockwise in the direction of clockwise direction, and turn counterclockwise. A screwdriver with a handle that can be struck at the end, but not used for electrical purposes.
Test pencil
It is also known as the test pen, which can only be operated if there is no electricity, which is the most basic requirement of power safety. It can check whether the low voltage line and the electrical equipment case are charged. For ease of carrying, the test pen is usually made of a pen, the front part is a metal probe, and the inside is filled with a safety resistor, a neon tube and a spring. The spring is in contact with the metal body at the end of the pen. When used, the hand should be in contact with the metal body at the end of the pen. The measuring voltage range of the measuring pen is 60 ~ 500 volts. Before use, it is important to verify whether the neon tube can glow normally on the normal power supply to confirm that the test pen is reliable. Because the neon tube is weak, it should be shielded from light when tested in bright light.
Combination pliers
Clamp or cut off metal wires with the hand, and the wire pliers with the cutting edge can also be used to cut off the wire. This kind of clamp is 150, 175, 200 mm, all with rubber insulated sleeve, can be suitable for 500 v below the live work. When used, protect the insulating sleeve so as not to lose the insulation. The wire clamp should not be used as a hammer, so as to avoid the dislocation of the cutting edge and the rotation axis, which affects the normal use.
Long nose pliers
Used for pinching workpieces or wires, especially suitable for small working areas. There are three kinds of specifications: 130, 160 and 180 mm. An insulated conductor for an electrician. Some with a cutting edge, can cut small parts.
The electrician knife
In the installation and maintenance of electrician, the insulation layer, cable insulation and wood trough are used for cutting wires, which have large size and small size. The length of the six blade is 112 mm; The small blade is 88 mm long. Some electrician knife has saw blade and awl, can use to saw small wood chip and conical hole. The electrician knife has no insulation protection and no live work. Use electric knife to avoid cutting hard material to protect the edge of the knife. The edge of the knife is blunt and can be worn with oil. If the blade is partially damaged, it can be worn with grinding wheel, but it must prevent annealing.
