Problems solved by technology
[0002] High-frequency line protection is directly related to the safe operation of the main network; high-frequency channels often have "channel abnormality" defects randomly and suddenly; at present, the necessary equipment for quickly troubleshooting fault points is a high-frequency level meter, and there are many inconvenient
[0003] Commonly used high-frequency level meters have the following disadvantages: 1. Heavy weight: each weighs about 18 kg; 2. Complicated operation: there are 15 adjustable switches and wiring; 3. Power supply required: in the outdoor field, away from work The power point requires a 220V AC power panel, of which the AC power panel is 45 meters long and weighs 6 kg; 4. Preheating is required: it takes 2 minutes for the frequency selection level meter, and at least 3 minutes for the vacuum tube millivolt meter; 5. Valuable equipment : The equipment is stored in the laboratory, which is very inconvenient for emergency use at night
