In the six to 10,000 volt substation and distribution personnel, according to the signal must not be used for different purposes, the commonly used models have infrared signals and wireless signals, and then can be used for driving operations.
-
In the 61 pkp elevator, the elevator is not allowed to use the diagram according to the signal, but the commonly used signal, some put so seven, do not follow the signal normal light to continue.
-
In the distribution and distribution of six to 10,000 volts, if the common diagram is based on the different signals, then the commonly used models should be digital signals and infrared signals and so on.
-
In 6-10kV substations, according to the different uses of signals, the commonly used signals are (CDE). A, sound signal B, light signal C, position signal D, accident signal E, warning signal.
-
In the process of power transformation and distribution, the signal can not be used, the signal is different, we have to identify different jumping green distribution according to different models and uses.
-
The battery is equipped with the east according to the signal, the commonly used signal for different purposes will have a Unicom, mobile or something.
-
Of course, there is, but it can't be without this signal.
-
Commonly used signal transmission, data acquisition relies on control cables.
-
There are commonly used signals in substation and distribution according to the different uses of signals, and I think it is better if the signal is strong.

Press the power system where the substation is located.
The position, role and characteristics are divided into: system hub substation, regional primary substation, secondary substation in the ground file guess area, and terminal substation.
The hub substation is located at the pivot point of the power system, and its voltage is the highest transmission voltage of the system, the current voltage level.
There are 220kV, 330kV (Northwest Power Grid only) and 500kV, the hub substation is connected into a ring network, and after the power failure of the whole station, it will cause the system to be disconnected, and even the whole system is paralyzed, so the reliability requirements of the criminal hub substation are higher.
The main transformer of the hub substation has a large capacity and a wide range of power supply. The regional primary substation is located at the pivot point of the regional network, which is a regional power receiving substation connected to the main transmission network, and its task is to receive power directly from the main network and supply power to the power supply area. After the power outage of the whole station, it can cause the collapse of the regional power grid and affect the power supply of the entire region.
The voltage level is generally 220kV or 330kv.
The main transformer capacity of the primary substation in the region is large, the number of outgoing circuits is large, and the reliability requirements for power supply are also relatively high.
The regional secondary substation receives power from the regional primary substation, and directly supplies power to the local load, the power supply range is small, and the capacity and number of main transformers are based on the power load.
Depends. After the power outage at the whole station, only the local area lost power.
The terminal substation is at the end of the transmission line, close to the load point of the good cavity, and directly supplies power to the user after the voltage is reduced.

Answer: Kira] Punch and bend: a, c, d
According to their different roles in power transmission and distribution in the power system, power transformers can be divided into step-up transformers, step-down transformers and distribution transformers; According to its different cooling medium, it can be divided into dry-type transformer and oil-immersed transformer.

6 What are the types of power transformers used in 10kV substation and distribution according to winding insulation and cooling methods? Each applies.
6 What are the types of power transformers used in 10kV substation and distribution according to winding insulation and cooling methods? 6 10kV substation and distribution transformers mainly have three types: dry-type transformers, oil-immersed transformers and oil-cooled transformers. 1.
The dry-type transformer is to pressurize the oil into air, insulate the windings by air, and then cool the display transformer. Due to the advantages of small package size, good vibration resistance, high insulation performance, and light weight, dry-type transformers are generally used in low-voltage power grids and low-voltage loads. 2.
An oil-immersed transformer is a special type of transformer in which both windings are immersed in a transformer container. It can gently insulate the windings, so as to effectively control the short-circuit current, and the orange has better insulation and vibration resistance, which makes its unit cost very high, even in the 6000 10 000V high voltage power grid it is also commonly used. 3.
The oil-cooled transformer is to immerse the transformer in the transformer container into the electrical insulating oil around the Wudan group, use the oil as the medium to transfer heat, and use the fan cooler to dissipate the heat. Due to its common use in high-voltage systems, the sibling shed has a large capacity and can reach a rating of 6000 10 000V. Oil-cooled transformers are widely used because of their low vibration and temperature rise, so they are more reliable and more affordable than oil-immersed transformers.

Answer]: B According to the provisions of Article 1 of the "Design Code for Substations of 20kV and Below" (GB 50053-2013), substations should be arranged in a single layer. When a double-layer arrangement is adopted, the transformer should be located on the ground floor, and the distribution room on the second floor should be equipped with a passage, platform or hole for handling equipment.
Silver Jane. According to the provisions of the article, a separate duty room shall be set up for the source of the substation with people on duty. The duty room should be directly connected to the distribution room or through the passage, and the duty room should have a door leading directly to the outside or to the walkway outside the substation. When the low-hail voltage-containing distribution room is also used as a duty room, the area of the low-voltage distribution room should be appropriately increased.
