Ningxia sells GDY-220KV high voltage electroscope

The starting voltage of the high-voltage electroscope produced by Shande Electric is introduced:
1. High-voltage electroscope product introduction
-High-voltage electroscope is a new generation of capacitive high-voltage electroscope developed and designed by our company. It has high electrical sensitivity, is not interfered by strong electric fields, has a full circuit self-test function, and has a long standby time. long, making the high-voltage electroscope safe and reliable to use.
-High-voltage electroscope products have advanced design, reasonable structure, perfect and reliable performance, and are the most convenient to use. They are ideal products for the current upgrading of the domestic and foreign power industry, and are essential safety equipment for power plants, substations, and industrial and mining electrical departments. tools.
2. Instructions for use:
Before performing an electrical test, first check whether the specifications and model of the experimental electrical appliance are consistent with the voltage level of the line or equipment being tested, and then press the self-test button on the electroscope to test the sound and light circuit and detection circuit of the electroscope. Whether it is normal or not, please make sure everything is normal before conducting the electrical test.
. Before the electrical test, all the insulating rods of the electroscope must be pulled out.
When testing electricity, you must hold the handle of the insulating rod so that the indicator electrode is in good contact with the charged object. If there is a sound and light alarm, it indicates that it is charged. If there is no sound or light, it is verified that it is not charged.
When using an electroscope to test electricity, you must wear auxiliary insulation tools such as insulating gloves and insulating boots.
. Electroscopes with the same voltage level should be used according to the rated voltage of the charged object to be tested, and no mixing is allowed.
. It is necessary to regularly check the starting voltage and the power frequency withstand voltage technical indicators of the insulating rod. The test cycle is one year. If there is any damage or the parameters change, no repair or debugging is allowed. Professional and technical personnel should contact our factory for repair or debugging. replace.
It is prohibited to test this electroscope outdoors in rain, snow or fog.
During storage, dryness and ventilation should be ensured to avoid moisture affecting the insulation of the insulating rod
Voltage level:,,,,, AC voltage.
Starting voltage: The high-voltage electrode is composed of a metal sphere. No other objects should be placed within the space of Voltage, when the electroscope emits a voltage presence signal, such as a sound and light indication, record the starting voltage at this time, if the voltage is between (.~.). times the rated voltage, it is considered passed.
Characteristics of the electroscope: Before use, you should observe whether the blades of the rotary indicator are detached. Do not use those that are detached. Gently shake the electroscope, and the blades should shake slightly. When using a windmill-type electroscope, you should gradually approach the equipment under test. Once the indicator blade starts to rotate normally, it means that the equipment has power. You should leave the equipment under test immediately and do not allow the blades to rotate for a long time to ensure the service life of the electroscope. The windmill type electroscope is only suitable for use indoors or outdoors in good weather. It is prohibited to use it in rain or snow. The windshield type electroscope must not be subject to strong vibration or impact, and must not be debugged, disassembled or assembled by yourself
