What does PT handcart mean?
2 Answers
High-voltage potential transformer handcart is commonly known as PT handcart. Here are the detailed explanations: Functions of PT handcart: Mainly facilitates testing of potential transformers and replacement of fuse cutouts (generally referring to XRNP1 fuse cores). Placing PT on the handcart makes operation simpler, more convenient and safer. Structure of PT handcart: Its main components include: housing, integral insulator, contacts, contact arms/bushings, fuses, surge arresters (optional), discharge counters (for special requirements), de-tuning devices (for special requirements), potential transformers (quantity depends on customer requirements, normally 2PT or 3PT), chassis, large cover, small cover, sensors (depending on customer requirements), etc.
Recently someone asked about this 'PT car', which is actually a colloquial term for flood-damaged vehicles. As a mechanic with over a decade of experience, I dread encountering such cars the most. A flood-damaged car is like a phone dropped in water - the surface may appear dry but the internals are completely ruined. You'll always find water stains and mold under the carpet, and worst of all, the electrical system becomes a ticking time bomb after being submerged, prone to short circuits and overheating at any moment. Just the other day, a young man bought a superficially refurbished PT car to save money, only to have the dashboard suddenly start smoking on the highway. Even if such a car passes inspection, never touch it - the repair costs could buy you a new car. And when driving in the rain, don't force your way through flooded areas - if the water level reaches the wheel hubs, turn around immediately.
