I. Uses:
This machine is used to obtain a large number of charges and tens of thousands of volts of high voltage in the experiments of electrostatics, together with its
other instruments to carry out experiments related to the conductor surface charge release, electrostatic field of the power line, tip discharge
and vacuum tube discharge. It can also be used for a series of experiments, such as electrostatic induction, fire
flower discharge, tip discharge and capacitor capacitance change and so on.
II. Characteristics:
The conductive layer in the conductive disk of this machine is coated with electric substance, the coating is firm and has a long service life.
Overcome the original use of aluminum foil bonding easy to fall off the shortcomings, and can improve the starting performance, in the humid
In the humid climate and rainy days can still maintain a good starting effect.
III. Main technical parameters:
Diameter of starter disk: 235mm, 275mm
Ambient temperature: -10 degrees Celsius to 40 degrees Celsius
Discharge distance:
1, in the relative humidity of 65% of the environment spark discharge distance ≥ 55mm
2, in the relative temperature is less than 80% of the conditions of spark discharge distance ≥ 30mm
V. Principle of Electricity Generation
The starter is a kind of instrument that utilizes induction to generate electricity.
When the two starter discs rotate rapidly, the charged system, especially the ball of the discharge fork equipped with an insulated handle, will accumulate a large amount of charge of different electrical properties, thus realizing the process and change of current discharge.
The electric current is discharged by the process of inductance and the change of electric current.
VI. Operation and Troubleshooting
The induction starter must be used on a clean and dry surface, otherwise it will be difficult to energize. To
clean the surface, use a soft brush or soft dry cloth to remove dust from the starter. As a general rule, the
The instrument needs to be kept in a dry environment and should be wiped with a dry cloth after wet weather or when the instrument has been exposed to moisture.
Wipe clean with a dry cloth after wet weather or when the instrument has been exposed to moisture.
In some cases, loss of contact or poor contact between the neutralizing brushes and the conductive layer may cause the instrument to fail to start properly.
Therefore, it is necessary to check it at any time, in order to ensure that the contact is good, it is necessary to replace the damaged brushes if necessary.
In order to ensure good contact, it is necessary to replace the damaged brushes if necessary. When the neutralization brush and the collector bar are installed in the opposite position, the instrument will not be able to start the electricity, which should be paid special attention to.
Special attention should be paid to this point. Set the crank handle as the front, the rear belt cross. The brush position should be inclined to
The brushes should be positioned diagonally to the upper left and upper right (as shown in Figure 3) at an angle of about 45° to the vertical line, and the front and rear brushes should be at right angles to each other.
