Electrical appliances are instruments that detect whether objects are charged and roughly estimated. The typical structure is shown in the figure on the left.When the conductor of the tested object is exposed to the top of the electrical appliance, the charges they bring are passed on to the foil in the glass cover.Because the same type of charge is repulsive, the foil will be automatically separated, and Zhang Cheng will be automatically separated.Based on the size of the two foils, it is estimated that the size of the objects power is estimated.
How to use electrical appliances
How to use low -voltage electrical appliances: Before use, you should first check the integrity of the electrical pens. Whether the four major components are lacking, whether the bubbles are damaged, and then verify it in a place with electricity.Perform electricity check.When using, be sure to hold the metal hook or tail screw of the pen hat, and the tip of the tip of the pen tip is contacting the strip equipment.How to use high -voltage electrical appliances: When checking the electricity, the operator must wear insulating gloves and insulating boots to prevent the damage to the human body by step voltage or contact voltage.The operator should be checked on the electrical equipment below the handling ring below the hood.During the inspection, it should be gradually moved near the band -mounted equipment until it glows or sounds to verify the integrity of electrical appliances.Then detect on the equipment that requires electricity checking.When the multi -layer lines are checked in the same rod rack, the low pressure should be verified first, the high pressure is tested, and the lower layer should be verified.
Electrical Electrical Production
Step 1: First of all, the bottle cap of the glass bottle must be removed, and then the center of the bottle cap is nailed to nail a small hole. The size of the small hole is about the diameter of the wire.Remove a distance from the outer end of the ends. At this time, you need to use the piping of the thread to remove about 3cm. After the subtraction, you can pass through the glass bottle of the wire.Step 2: After wearing the wires, cut the aluminum foil and cut the aluminum foil into two pieces. The length of the two aluminum foil is 6cm, both, and the width of 0.5cm, and then fold the two aluminum sheets.In the future, a small hole is hit on the upper end of the two aluminum foil. After the small holes are touched, the wires that can be penetrated into the bottle cap are also passed through the two foils, and the wire is twisted into a ring shape to speed up the passing speed.Step 3: After completing the wiring and foil, put the prepared lime into the glass bottle, because the lime can be chemically reacted at the normal temperature environment, which can be used as a desiccant for the device. Finally, the glass bottle of the glass bottle can be finally.Just cover it.At this time, the production of electrical appliances is completed.
The role of electrical appliances
1. Check whether the conductor is charged.Will be tested directly with the metal balls of the electrical appliances directly or connected to the two with a wire. Observe whether the electrical gold foil is opened, you can determine whether the conductor is charged.You can also close the tested conductor that is not in contact with the electrical appliances and is close to its metal ball. If the conductor is charged, the metal ball and gold foil of the electrical appliances are also sensoring the alien charges and the gold foil will be opened.2. Check the electricality of the conductor.Let the metal balls that have been used with the electrical appliances that have been used to be close to the tested conductor are approaching. If the gold foil of the electrical appliances becomes larger, it means that the tested conductor is positive electricity.The charge on the top moved to the gold foil and made it bigger.If the golden foil of the electrical appliances becomes smaller, it means that the tested conductor is negative or without charging. This is due to the suction of the opposite sex charge, so that the positive charge on the gold foil to the metal ball to make the corner smaller.In this case, the tested conductor can approach the metal ball of the electrical appliances that are known to be known as the negative power. If the gold foil becomes larger, it can be confirmed that the tested conductor must be negative.

The working principle of electrical appliances
When inspection is tested by electrical appliances, objects are generally exposed to metal plates.Once the object is charged, the charge will be transmitted to the two gold foil. Because the power of the gold foil is the same and the charge is the same, it will be rejected with each other.In this way, the gold foil will be opened, and the size of the opening is dependent on the amount of charge. The more the electricity is, the larger the open angle.When the object itself does not have a point, the gold foil will not be separated.
