How to design the substation architecture, what is the architecture

The structure of the substation is divided into cement and steel structure, and there are gate types and types. It also depends on the single-layer or multi-layer arrangement of the equipment.

Definition A rigid frame combination used for suspension conductors, support conductors, or switchgear and other electrical equipment.

Substation biàndiànzhàn. (1) Refers to a power system substation with one or more converters, that is, a place where voltage is raised and lowered, and electric energy is controlled and distributed.

2. Citations and Explanations.

In the power system, it is a place to raise and drop voltage, control and distribute electric energy. It is mainly equipped with transformers, power distribution devices and control equipment, etc., and some are also equipped with phase modulation equipment such as condensers or capacitors to regulate voltage. According to the size of the scale, it is called a substation, a substation, a substation, etc.

4. A villager surnamed Luo from Niumiandi Village, Jiancun Village Committee, pointed to another oil-stained river not far away and told Li Hu that a month ago, after a fire broke out at the Zengcheng substation upstream, he found that the water surface was full of oil.

5. Starting from the actual situation of substation engineering construction, the method of reducing the grounding resistance of substation is analyzed, in order to benefit the construction of substation grounding network.

The structure in the substation refers to the load-bearing structure composed of steel pipes or concrete poles for hanging bus bars and leads, and is generally the highest equipment in the substation except for lightning rods. The bracket refers to the support of switches, switches, four small devices and other equipment, which is generally a truss structure composed of angle steel. Of course, there are also some devices that may sit directly on the foundation and do not have a stand.

The main difference between the two is that the former is suspended, and the latter is supported.

Hello dear, the requirements of the State Grid substation structure are as follows: the State Grid substation spike structure is generally designed according to the voltage level, generally more than 6 meters, and the height is 12 meters. When dismantling, the first type of work ticket for substation or the first type of work ticket for the line should be handled.

The general steps of the civil construction process of the substation are as follows: 1. Level the site; 2. Excavation frame foundation, house foundation, and then equipment foundation; 3. Cable trench construction, pay attention to the cable trench construction should be considered and reserved with the equipment, kiss hello, I hope the answer can help you.

The box transformer generally adopts the structure of each unit independent of each other, which is equipped with a transformer room, a high-voltage switch room and a low-voltage switch room, which are connected to a complete power supply system through wires.

The transformer room is generally placed at the rear. In order to facilitate the needs of users for maintenance, replacement and capacity increase, the transformer can be easily pulled out of the box or hoisted out of the upper part.

Because the transformer is placed in the shell, its favorable factor is that it can prevent the temperature rise caused by direct sunlight irradiating the transformer, and at the same time, it can also effectively prevent external collisions, impacts and touch shock accidents; The disadvantage is that it puts forward higher requirements for the heat dissipation of the transformer.

The high-voltage switch room is installed with an independent enclosed high-voltage switchgear, and the cabinet is generally installed with a gas-producing type, compressed gas or vacuum type load switch-fuse combination electrical appliance, and the high-voltage fuse installed on it can ensure that any phase fuse can make its main switch open when it is fused, so as to avoid phase loss operation.

In addition, it is also equipped with grounding switch, which is interlocked with the main switch, that is, only after separating the main switch, the grounding switch can be closed, and after the grounding switch is closed, the main switch can not be closed, so as to ensure the safety during maintenance.

Box-type substation (referred to as box-type substation) is a kind of high-voltage switchgear distribution transformer, low-voltage switchgear, electric energy metering equipment and reactive power compensation device combined in one or several boxes according to a certain wiring scheme. It is suitable for use in three-phase AC systems with a rated voltage of 10 for the use of lines and distribution of electrical energy.

Compared with the European box with the same capacity, the structure of the American box is more reasonable. Because the European-style box transformer is installed in the same metal shell box with the transformer and ordinary high-voltage electrical equipment, the room temperature of the transformer is very high, which causes heat dissipation difficulties and affects the output; On the other hand, ordinary high-voltage load switches, fuses and low-voltage switchgears are used in the box, so the European-style box transformer is larger. The structure of the American-style box transformer is different from that of the European-style box transformer.

From the perspective of layout, its low-voltage room, transformer room, and high-voltage room are not arranged in a zigzag pattern, but in a zigzag layout. From the structural point of view, this box-type variant is divided into two parts, front and rear for high and low voltage operation intervals, and the operation interval includes high and low voltage terminals, load switch operating handles, no-load voltage regulation section switches, plug-in fuses, oil level gauges, etc.; The rear part is the oil injection tank and heat sink, and the transformer winding, iron core, high-voltage load switch and fuse are put into the transformer oil tank.

The arrester also adopts an oil-immersed metal oxide arrester. The transformer cancels the oil pillow and adopts the principle of constant volume of oil and air gap to design the sealed oil tank, and the oil tank and radiator are exposed to the air without heat dissipation difficulties. The low-voltage circuit breaker adopts the molded case circuit breaker as the main circuit breaker and the outgoing circuit breaker.

Due to the simplification of structure, the floor area and volume of this box-type substation are greatly reduced, because its volume is very small and only one side opens the door, its required floor area is only 1 4 of the European-type box transformer, and the volume is only 1 5-1 3 of the European-type box transformer of the same capacity. The high-voltage side of the American-style box transformer is protected by a fuse, and the low-voltage side is protected by a molded case automatic air circuit breaker, which is the same as the protection method of China's 10kV distribution transformer. The high-voltage fuse protects the transformer from internal faults, and the automatic air circuit breaker protects the low-voltage side line from overcurrent, short circuit, and undervoltage faults.

The shortcomings of the American box transformer. Because the load switch is immersed in oil, the oil is carbonized and decomposed by the arc, producing harmful gases such as acetylene, which reduces the performance and causes accidents. No obvious disconnection point can be seen, and maintenance is inconvenient.

Because the low-voltage protection and metering methods in the United States are different from those in China, the American-style box transformer itself does not carry low-voltage protection and metering. In order to meet the needs of domestic users, domestic box transformers are equipped with low-voltage distribution cabinets on the low-voltage side. Because the box-type transformer is under the direct sunlight for a long time, it affects the heat dissipation of the molded case circuit breaker, so that the circuit breaker can not normally break the load and short-circuit current, which is easy to cause high-voltage side faults.
