Q1: What is the working principle of capacitor compensation cabinets?
A1: Capacitor compensation cabinets provide reactive current compensation to the grid by paralleling capacitors, thereby reducing reactive currents in the grid and improving the power factor.
Q2: What are the main components of a capacitor compensation cabinet?
A2: Main components include the cabinet shell, busbars, circuit breakers, isolating switches, thermal relays, contactors, surge arresters, capacitors, reactors, primary and secondary wiring, terminal blocks, and automatic power factor compensation control devices.
Q3: How do capacitor compensation cabinets improve power supply quality?
A3: By compensating reactive power, they improve the power factor, reduce line losses, enhance voltage quality, and thus improve overall power supply quality.
Q4: Do capacitor compensation cabinets require regular maintenance?
A4: Regular inspections and maintenance are necessary to ensure normal operation. Maintenance includes checking capacitor capacity, testing control system performance, cleaning equipment, etc.
Q5: What is the lifespan of a capacitor compensation cabinet?
A5: Typically lasts over 10 years, depending on product quality, usage environment, and maintenance practices.
