What equipment are used in the power, can help to divide some of the details, as well as the type of equipment under the type of equipment
3 from the degree of importance can be divided intoCore equipment and auxiliary equipment4 from the price can be divided intoLarge valuable equipment, general equipmentPower plant and substation electrical equipment is divided into primary equipment and two equipment. A device (also known as the main equipment) is the main component of the power system, it is the direct production, electricity transmission and distribution equipment, including power generators, power transformers, circuit breaker, isolating switch, power bus, power cables and transmission lines. The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer. The primary equipment and its connected circuit is called primary circuit. Two equipment in accordance with certain rules to connect to achieve some technical requirements of the electrical circuit called the two circuit.Relay protection and safety automatic device, dispatching automation and communication system are the two systems.
Power equipment classification:1 the sequence of electric power in power system can be divided intoPower generating equipment, power generation equipment, power transmission equipment and electric equipment2 the main role of the power system can be divided intoPrimary equipment, two equipment
When drawing the main wiring diagram, the transformer, arrester, capacitor, neutral point equipment and carrier communication can be used to reflect the situation of power supply in normal and accident conditions. Electrical wiring is also known as the main electrical
