Q: What are the two power distribution equipment?: Such as measuring instrument, relay, switch, button operation and automatic control to provide some of these devices the energy supply device, signal equipment, computer equipment, and control cable (such as batteries, silicon rectifier, etc.).

Q: What are the distribution network equipment: suburbs, towns and rural areas, further allocation and supply industry, agriculture, commerce, industry and residents with special needs for electricity secto

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: 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 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: Transmission system and distribution system: Distribution system is the power supply to the distribution load for the purpose of the general voltage level of not more than 10KV

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: Main equipment of high voltage direct current transmission: It is composed of two or more converter bridges, which can realize the AC DC AC converter.

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
