Safety precautions in the use of high voltage electrical equipment
Release time:
2020-09-01
1. Quality control of high-voltage electrical equipment during maintenance The maintenance personnel of high-voltage electrical equipment must be professionally trained and familiar with the internal structure of the equipment; the professional and technical personnel of the user unit must prepare practical maintenance procedures. Disassembly and maintenance of high-voltage electrical equipment should be carried out in dry weather with atmospheric humidity below 60%. At the same time, attention should be paid to prevent dust, impurities and moisture from invading its interior. If necessary, dry hot air should be continuously introduced into the air chamber for maintenance to keep the interior dry.
2. Abnormal sound analysis judges that the internal discharge sound of high-voltage electrical equipment is similar to the sound of light raindrops falling on the metal shell. Because the frequency of local discharge sound is relatively low and the sound quality is different from its noise, sometimes the ear must be attached to the shell to hear it. If the discharge sound is weak, it is difficult to distinguish whether the discharge sound comes from inside or outside the electrical appliance, or it is impossible to judge whether the discharge sound, through partial discharge sound, check the equipment regularly.
3. Personal safety protection in the use of high-voltage electrical appliances (1) indoor SF6 high-voltage electrical appliances, should pay attention to the main control room for airtight isolation;(2)SF6 equipment indoor must be equipped with ventilation equipment, into the indoor ventilation first;
