What does receiving electricity mean, what is receiving electricity, and what is feeding

Electricity transmission is the effect of voltage on it.

Power Transmission: The power plant delivers electricity to the consumer. For example, the surplus power in the northwest can realize cross-regional network power transmission.

The power receiving end of the user refers to the property right demarcation of the power supply facility. The power supply and receiving end of the high-voltage special line is the same voltage bus of the substation of the power supply enterprise, and the power supply line belongs to the public use, which is the user's power receiving bus. If the line of the low-voltage power supply user belongs to the user, it refers to the low-voltage bus of the power supply transformer, and the line belongs to the public line, and the power supply side of the electric energy meter is billed for the user.

The electrical equipment of the electric traction locomotive to obtain electrical energy from the catenary is installed on the roof of the locomotive or motor car. The pantograph can be divided into two types: single-arm bow and double-arm bow, both of which are composed of a slide plate, an upper frame, a lower arm bar (a lower frame for a double-arm bow), a base frame, a rising bow spring, a transmission cylinder, a support insulator and other components. Diamond pantographs, also known as diamond pantographs, were very common in the past, but were gradually phased out due to high maintenance costs and easy to break the catenary in the event of a failure, and in recent years, single-arm bows have been mostly used (see figure).

The smoothness of the load current through the contact surface between the contact wire and the pantograph slide plate is related to the contact pressure, transition resistance, and contact area between the slide plate and the contact wire, and depends on the interaction between the pantograph and the catenary.

There is a voltage acting on it.

Well, power delivery.

As the name suggests, receiving power is to accept and transmit power, and feeding is to send out electricity, these two special terms are generally commonly used in the field of cable TV technology, and the amplifiers in the cable TV network often rely on the remote power supply to feed to provide power supply, and these amplifiers can not only receive electricity, but also provide a feeding path for the next level of amplifiers.

Receiving device The power transmission device refers to the relationship between the power supply unit and the power consumption unit. According to the provisions of the Electric Power Law, the first point before entering the user of a public institution and an individual unit is the demarcation, and the power supply device in front of the user is the power receiving device. According to the power credits, power supplies, switches, circuit breakers, and wires are sending point devices.

Load, for the power receiving device.

Power receiving engineering refers to the general term for the construction of electrical facilities such as the power line part and the customer's power substation (distribution) power station located on the customer side at the demarcation point of property rights.

It means to get electricity. For example, the relay is powered by the relay, which means that the relay gets the working voltage.

The meaning of power transmission.

Welcome and wish you happiness.

Receiving electricity, in other words, means that the load or power supply is primary, and the receiving power is secondary.

The power receiving cabinet is a kind of switch cabinet, which is a switch cabinet that introduces power from the outside.

The power receiving cabinet usually introduces 10kV power supply from the power supply network, and the 10kV power supply sends the electric energy to the 10kV bus through the switch cabinet, and this switch cabinet is the incoming power cabinet. 35-110kV and above voltage level.

The substation and incoming cabinet are all referred to as the transformer low-voltage (10kV) switchgear. That is, the first cabinet connected to the initial end of the 10kV bus by the output of the low-voltage side of the transformer: it is called the inlet cabinet, also known as the variable low inlet cabinet.

Incoming cabinet: also known as the power receiving cabinet, is a device used to receive electric energy from the power grid (from the incoming line to the bus), generally installed with circuit breakers, CT, PT, isolation knives and other components. Outlet cabinet:

Also called the feeder cabinet or distribution cabinet, it is a device used to distribute electrical energy (from the bus bar to each outlet), and is generally installed with circuit breakers, CT, PT, isolation knives and other components.

The user's power receiving project is a power project funded by the user, which is the new installation, capacity increase, and change of electricity consumption of the customer's assets.

Power distribution refers to the process of transmitting electricity from the power source to the load center according to the load demand.

Feeder is the meaning of power transmission, for example: feeder is the professional term for power transmission line; The feeder cabinet is called the power transmission cabinet.

Since they all have the meaning of power transmission, what is the difference between power distribution and power feeding?

Personally, I believe that the scope of power distribution is wider, divided into high-voltage distribution, medium-voltage distribution and low-voltage distribution, which is a more comprehensive concept, including substation, transmission, protection, control, use and other content.

Transmission and feeding, on the other hand, only contain the concept of transmitting electricity.

Receiving electricity is better understood as the process by which the load center receives the input of electricity.

The generation and reception of electricity is usually for a certain regional power grid. It is easy to understand in two steps: power generation refers to the amount of electricity produced by the power plant itself and transmitted to the grid company in the region; Electricity received refers to the amount of electricity obtained (received) from other regions, usually the amount of electricity produced by power generation enterprises in other provinces through inter-provincial transmission, and the amount of electricity received by the power grid of the region.

The two are collectively referred to as generating and receiving electricity.

Further, the power received can be positive or negative, and the power received is positive, which means that the electricity presents a net input relationship, and the electricity received is negative, which means that the electricity presents a net output relationship. In reality, power grids such as North China and East China generally receive positive electricity, which is manifested in the fact that part of the electricity is transmitted from other regions to the region; For example, in the southwest and northwest power grids, the power reception is generally negative, which is manifested in the fact that part of the electricity is transmitted from the region to the outside area.
