Advantages of Outdoor Switchgear
First, let's take a look at what an outdoor switchgear is? Outdoor switchgear actually refers to substations installed outdoors, which can be used to receive and distribute electricity, and can also be understood as the 10kV distribution room of a power station. In practical applications, the situation is that the outdoor switchgear expands step by step from the power station, solving the limitation of limited space in the power station, while providing users with sufficient power interfaces, forming a ring network power supply network, which can connect to the power supply from both sides of the outdoor switchgear.
1. Classification of outdoor switchgear
According to the different internal switch cabinets, outdoor switchgear can be divided into primary outdoor switchgear and secondary outdoor switchgear.
Primary outdoor switchgear is generally constructed in Class A and B areas, used for the main network of routes. Under normal circumstances, outdoor switchgear uses dual power supply switches with three-phase five-wire, with each route coming from different substations or different busbars of the same substation. When on-site standards are not available, at least one route must use an external power source, while the other route uses the inter-line of the outdoor switchgear.
Secondary outdoor switchgear is used for residential communities or main lines and end users, serving the function of carrying household loads and small to medium-sized enterprises as well as end-of-line loads. It generally uses dual power supply switches with three-phase five-wire, with one route coming from the substation, and the other route can come from public distribution equipment routes.
2. Functions of outdoor switchgear
The types of switch cabinets inside outdoor switchgear may vary, but the functions are basically the same. They mainly provide 10kV high-voltage power to end users, while also having the functions of intelligent power disconnection and circuit protection. The emergence of outdoor switchgear has liberated the distribution room of the power station, adopting a ring network power supply system, which improves the stability of power supply.
Outdoor switchgear is often used in places with high electricity consumption. Generally, this is due to the need to install multiple distribution rooms or box-type substations, and there is not enough 10kV incoming power supply, so outdoor switchgear is installed to increase the 10kV power supply access points to meet the electricity demand of each distribution room and improve distribution stability.
