In power systems, switchgear primarily includes circuit breakers, disconnect switches, earthing switches, and load switches. These devices play a critical role in the operation and safety of the electrical network.Circuit breakers can quickly interrupt the circuit in the event of a fault, protecting...

Abnormal temperature rise is a critical factor affecting the performance and safety of vacuum circuit breakers (VCBs).First, overloading is one of the main causes of increased temperature. When the load exceeds the design capacity, the current generates additional heat. Additionally, poor internal c...

Energy storage failure in earthing switches usually arises from several factors.First, mechanical faults are a major cause—particularly the wear or aging of springs, which can reduce the effectiveness of the energy storage mechanism. Additionally, electrical issues such as unstable voltage or poor c...

The safe operation of high-voltage electrical equipment depends on several fundamental requirements.First, the equipment must have excellent insulation performance to prevent leakage currents and short-circuit accidents. Second, regular maintenance and inspection are essential to ensure proper opera...

The overheating of switchgear contacts is typically caused by several factors.First, poor contact connections can generate excessive heat when current passes through. For example, loose bolts or contaminated contact surfaces can increase contact resistance, leading to overheating of the contacts.Sec...

In power systems, when a vacuum circuit breaker (VCB) operates under high-voltage conditions, its insulation performance and switching capability are significantly affected. High voltage intensifies the electric field strength, increasing the risk of insulation breakdown, which may lead to equipment...

The basic working principle of an earthing switch is to safely connect or disconnect electrical equipment from the ground by controlling the grounding point within the circuit. Its structure typically consists of contacts, a driving mechanism, and an energy storage device.During operation, the energ...

During operation, high-voltage equipment may experience mechanical jamming faults, typically caused by internal wear, insufficient lubrication, or the intrusion of foreign objects. When such jamming is detected, the equipment should first be shut down for inspection, and the affected components shou...

Switchgear is an indispensable component of power systems, primarily used to control, protect, and isolate electrical equipment. Its functions range from enabling the connection and disconnection of electrical currents to ensuring equipment protection during faults and preventing the escalation of a...
