How to judge the structure and support of substation?

2022-07-21

The structure of substation refers to the load-bearing structure composed of seamless steel pipe or concrete pole with busbar and conductor. Apart from lightning protection grounding, it is generally the largest equipment in the substation. Support refers to the power switch, knife switch, four devices and other equipment support, is generally Angle iron frame structure. 


Naturally there are some devices that are very likely to sit immediately and basically, there is no stand.

The key difference between the structure and bracket of the transformer is that the front one is the suspension, and the back one is the support point.


Substation key can be divided into: core substation, terminal equipment substation; Transformer substation, blood pressure lowering substation; Power supply system substation, industrial and mining enterprise substation, railway substation (27.5KV, 50HZ); 1000KV, 750KV, 500KV, 330KV, 220KV, 110KV, 66KV, 35KV, 10KV, 6.3KV and other rated voltage substation; 10KV substation; Box substation.


Use good electronic information technology, modern electronic information technology, communication technology and information resources management of substation secondary equipment such as technical (including relay protection device, control, precise measurement, data signal, common fault wave record, protection and telecontrol equipment, etc.) the role of reliability design, rearrange, A comprehensive automation technology that monitors, accurately measures, manipulates and harmonizes the operation of all substation equipment.


From the point of view of practical operation safety, the error prevention management system composed of control error prevention and substation micro-machine error prevention system software can give a strong technical guarantee for the safety of practical operation, but in addition, the reliability and consistency of the whole control management system has clearly put forward higher provisions. 


The single-machine version of traditional micro-machine error prevention system software for substation can not fully meet the current technical standards, and become a link of the lack of reliability in all system software. It has become a key link to improve the reliability of error prevention management system to complete the installation of two machines of the micro-machine error prevention system software in substation.
