开变所里面内容是什么？

中文版

开变所，即开关变电站，是电力系统中的一个重要环节。那么，开变所里面到底有哪些内容呢？

一、开关设备

开关设备是开变所的核心设备，主要包括断路器、隔离开关、负荷开关等。这些设备用于控制电路的通断，保护电力系统的安全运行。其中，断路器是最关键的开关设备，能够在短路或过载时迅速切断电路，避免设备损坏和事故扩大。

二、变压器

变压器是开变所中的另一个重要设备，用于将高电压变为低电压或将低电压变为高电压，以满足不同设备的用电需求。变压器的工作原理是通过电磁感应实现电压的升降变换，保证电力系统的稳定运行。

三、配电装置

配电装置是开变所中负责分配电能的设备，主要包括母线、开关柜、互感器等。母线是配电装置中的主要导电部分，负责将电能传输到各个开关柜。开关柜则用于控制电能的分配和传输，互感器则用于测量和保护电路。

四、辅助设备

除了上述主要设备外，开变所还包括一些辅助设备，如通风设备、照明设备、消防设备等。这些设备虽然不像主要设备那样直接参与电能的传输和分配，但对于保障开变所的正常运行和人员安全却至关重要。

What Is Inside a Switching Substation?

The switching substation, also known as the switchyard, is a crucial component of the electrical power system. So, what exactly is inside a switching substation?

I. Switchgear

Switchgear is the core equipment in a switching substation, mainly comprising circuit breakers, disconnectors, load switches, and more. These devices control the on/off state of electrical circuits, safeguarding the smooth operation of the power system. Among them, the circuit breaker is the most crucial switchgear, capable of quickly interrupting the circuit during a short circuit or overload to prevent equipment damage and accident escalation.

II. Transformers

Transformers, another essential equipment in the switching substation, convert high voltage to low voltage or vice versa to meet the power requirements of different devices. The transformers work by electromagnetic induction, enabling voltage transformation, thus ensuring stable operation of the power system.

III. Distribution Equipment

Distribution equipment in a switching substation is responsible for allocating electrical energy, including busbars, switchgear cabinets, transformers, and more. The busbars serve as the main conductive part, transmitting electrical energy to various switchgear cabinets. The switchgear cabinets control the distribution and transmission of electrical energy, while transformers measure and protect the circuits.

IV. Auxiliary Equipment

Apart from the aforementioned main equipment, a switching substation also comprises auxiliary equipment such as ventilation systems, lighting systems, and fire protection equipment. Although these devices do not directly participate in the transmission and distribution of electrical energy like the main equipment, they are crucial for ensuring the smooth operation of the switching substation and the safety of personnel.
