- Q:DC transmission equipment
- Power supply operation of power plant and substation in nowadays are used in DC power supply, it provides power for the control of the load and power load and DC emergency lighting load, is the foundation of modern electric power system control and protection
- Q:What is the difference between power supply and distribution
- The problem is you estimate from the injection test out the electric power, is the power system of power plant and the national grid is responsible for part of the design, the design of power plant and power lines, its design must be designed by a qualified electric power design institute
- Q:What is the role of transmission system and distribution system in power grid
- The distribution of power resources and power load centers in most countries in the world is inconsistent.
- Q:What is the power equipment in the distribution room?
- High voltage distribution room generally refers to the 6kV - 10kV high voltage switch room; low voltage distribution room is generally refers to the 10kV or 35kV station with variable line 400V distribution room
- Q:Are electric wires and cables belong to distribution equipment?
- Distribution equipment (Electrical Equipment) is in the electric power system of HV switchgear, generator, transformer, power circuit, circuit breaker, low voltage switch cabinet, distribution board, switch box, control box and other equipment collectively.
- Q:Rural high voltage transmission line equipment ownership
- the transformer can be what, look at the role of electrical appliances can be
- Q:AC distribution equipment including distribution box
- so there will be in the power distribution cabinet a reference line and a zero line selection of single-phase 6A can switch.
- Q:An introduction to the interpretation of flexible AC transmission systems
- synchronous compensator (STATCOM), reactive power distribution is mainly used to improve the system, to adjust voltage and improve the voltage stability of the system;
- Q:High and low voltage distribution equipment
- High voltage distribution equipment: high voltage fuse; high voltage isolation switch; high voltage load switch; high voltage circuit breaker.
- Q:Power distribution equipment should be prepared before the blackout?
- Before the power failure, the person in charge or the electrical appliance technician should fill in the work order.
