What is Indoor Switchgear ?

Indoor Switchgear Definition

Indoor switchgear is defined as a type of electrical switchgear enclosed in a grounded metal case, commonly used for medium voltages.

Indoor Switchgear Classification

Metal-enclosed indoor switchgear.

Metal-clad indoor switchgear

Gas-Insulated Systems

Indoor switchgear often uses GIS, insulated with SF6 gas, which has superior dielectric properties compared to air.

Metal-Clad Switchgear

This type of indoor switchgear is highly customizable and uses vacuum-type circuit breakers, offering isolated relaying and metering instruments.

Advantages of Indoor Substation

More reliable and safer

Takes lesser space than the outdoor system

Easier maintenance and durability

Lower operating costs

Reduced risk of electrocuting due to grounded metal enclosures

More security

Lesser prone to environment conditions

Limitations of Indoor Switchgear

The main drawbacks are higher installation costs and less economic viability for high-voltage applications.

Application of Auto-Reclosing Residual Current Protective Devices in Lightning Protection for Communication Power Supplies

Application of Auto-Reclosing Residual Current Protective Devices in Lightning Protection for Communication Power Supplies

1. Power Interruption Problems Caused by RCD False Tripping During Lightning StrikesA typical communication power supply circuit is shown in Figure 1. A residual current device (RCD) is installed at the power supply input terminal. The RCD primarily provides protection against electrical equipment leakage currents to ensure personal safety, while surge protective devices (SPDs) are installed on power supply branches to protect against lightning intrusions. When lightning strikes occur, the senso

Reclosing Charge Time: Why Does Reclosing Require Charging? What Effects Does Charging Time Have?

Reclosing Charge Time: Why Does Reclosing Require Charging? What Effects Does Charging Time Have?

1. Function and Significance of Reclosing ChargingReclosing is a protective measure in power systems. After faults such as short circuits or circuit overloads occur, the system isolates the faulty circuit and then restores normal operation through reclosing. The function of reclosing is to ensure continuous operation of the power system, improving its reliability and safety.Before performing reclosing, the circuit breaker must be charged. For high-voltage circuit breakers, the charging time is g
