Q: What are the general requirements for working on distribution equipment?: Can be plugged into the elbow cable connector, not load operation.

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: DC transmission equipment: DC screen commonly known as intelligent maintenance free DC power supply screen, referred to as DC screen, the general model is GZDW.

Q: What is the difference between power supply and distribution: Power supply and distribution is part of the use of general by the Architectural Design Institute of electrical professional

Q: Distribution system equipment classification: Mechanical equipment is made up of mechanism, power mechanism, transmission mechanism, actuator and control system

Q: High and low voltage distribution equipment: Distribution equipment refers to a variety of power plants, substations and factories and enterprises in the low-voltage power distribution system for power, distribution and lighting of the complete sets of equipment.

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: Main equipment of high voltage direct current transmission: The utility model comprises a converter, a converter transformer, a smoothing reactor, an AC filter, a DC lightning arrester and a control protection device.

Q: Power distribution equipment should be prepared before the blackout?: after the high and low voltage power failure, the work must be carried out before the first inspection
