Description
Technical Field
The invention relates to the technical field of substations, in particular to an arrangement structure of distribution device HGIS equipment.
Background
A power distribution device is a generic term for electrical devices capable of controlling, receiving, and distributing electrical power. The electric energy transmission and redistribution device has the functions of transmitting and redistributing electric energy in normal operation, rapidly cutting off fault parts under fault conditions and recovering operation. Since it is functionally complete, electrical equipment must have various functions in the power distribution device. Such as bus bars, circuit breakers, disconnectors, reactors, lightning arresters, transformers, reactive compensation devices, connection conductors, and measurement protection communications. Distribution devices can generally be categorized according to voltage class or, depending on differences in arrangement, indoor and outdoor distribution devices.
HGIS is short for gas-insulated composite electrical apparatus, according to different users' needs with components integration seal such as circuit breaker, isolator, earthing switch and mutual-inductor in gas-insulated metal casing. The HGIS equipment is a novel high-voltage switch equipment between GIS and AIS. The HGIS is similar in structure to the GIS, but it does not include bus bar equipment. The bus is not arranged in the SF6 air chamber and is exposed, so that the wiring is clear, simple and compact, the installation, maintenance and overhaul are convenient, and the operation reliability is high.
Along with the continuous expansion of the power grid scale, the ultra-high voltage transformer substation is greatly increased, and the main equipment of the ultra-high voltage 500kV transformer substation in China is very important in shape selection along with the environmental and occupied pressure. At present, 500kV ultra-high voltage switches in China mainly have two main types: a gas insulated metal fully enclosed switchgear GIS and a conventional open switchgear AIS. GIS has the characteristics of small occupied area, high operation reliability, strong pollution resistance and shock resistance, etc., but the GIS has the characteristics of high price, difficult repair in a short time after failure and difficult extension. AIS is cheaper than GIS, but area is very big and electrified part exposes more, has restricted the place application that is narrow and small and the environmental condition is abominable in the transformer substation area. Because the HGIS can integrate the advantages of the GIS and the AIS, and simultaneously avoid the defects of the GIS and the AIS, the application and the research of the HGIS are continuously carried out in China.
The 500kV and 330kV voltage levels of the domestic transformer substation are mainly connected by adopting one half-circuit breaker, and due to the characteristics of one half-circuit breaker, the number of the circuit breakers is large and the economy is poor although the reliability is high, so that the 4/3 circuit breaker connection mode can be adopted on the premise of meeting the reliability, and the cost performance is improved. The current 500kV and 330kV voltage class is generally four-row arrangement of 4/3 breaker wires, 3 incoming and outgoing wires are arranged in each 1 string of the 4/3 breaker wires, the current four-row arrangement is adopted, normal incoming and outgoing wire cannot be realized, if a heightened framework is adopted, the problem is solved in a crossing mode, the occupied area of a power distribution device can be obviously increased, the requirement of saving the land cannot be met, the consumption of basic concrete, the foundation treatment and the steel consumption cost of the framework can be greatly increased, the overall engineering economy is poor, and a plurality of inconveniences are brought to later construction, operation, maintenance and the like.
