Henan sells rod-type telescopic high-voltage electroscope

How to use Shande Electric's rod-type telescopic high-voltage electroscope (1) Before use, use an electroscope with an appropriate voltage level and a telescopic insulating rod according to the rated voltage of the equipment to be tested
(2) The electroscope should be self-checked before testing. During the test, press the self-test button and the electricity test indicator will emit intermittent oscillating sound and light signals, which proves that the performance of the electroscope is intact and you can proceed with the electricity test. At this time, the telescopic insulating rod can be pulled apart to perform the electricity test operation. Do not cross it with your hands. The specified safety ring, the electroscope contacts and the level of the live body touch, the mouth will emit intermittent sound and light signals, indicating that there is electricity, if no intermittent sound and light signals are issued, it means that there is no electricity
(3) Replace the battery, screw The battery can be replaced by opening the upper cover of the detector. The circuit of the machine works with an electronic automatic switch. It is continuously on standby for a long time. It turns on when there is a signal input and automatically turns off when there is no signal. It consumes little power and does not need to change the battery frequently, so it uses No. 3 silver oxide. Four batteries, voltage, consider replacing the battery when no sound and light signals are emitted during self-test
(4) The electroscope should follow the electrical industry safety work regulations when performing power tests on electrical equipment. To ensure the safety of personal equipment Regular preventive tests are required according to electrical industry safety regulations
High-voltage electroscopes are mainly used to test high-voltage electrical equipment whose ground voltage is above the equipment. At present, three types are widely used: luminous type, sound and light type, and windmill type. They generally consist of three parts: the detection part (indicator part or windmill), the insulation part, and the handshake part. The insulating part refers to the part from the metal connecting screw at the bottom of the indicator to the cover guard ring, and the handshake part refers to the part below the cover guard ring. The insulation part and handshake part have different lengths according to different voltage levels.
Before the electricity test operation, the electroscope should be self-tested by pressing the self-test button and the electricity test indicator should send out a clear audible and visual alarm signal. If there is no sound and light indicator signal during the self-test, the electrical test operation is not allowed. Before the electrical test operation, it is also necessary to check whether the grounding down lead is intact and whether the contact point is reliable. The sequence of connecting the ground down conductor is to clamp the ground roll of the ground down conductor to a good ground rail or pole reliably. Insert the plug at the upper end of the grounding down wire reliably into the jack at the end of the first pole
