Description

Technical Field

[0001] This utility model belongs to the field of switchgear technology, specifically a new type of high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is widely used in power systems, industrial and mining enterprises, and rail transportation. In power systems, it controls, regulates, and distributes current, playing a crucial role in ensuring safety and control. In industrial and mining enterprises, high-voltage switchgear ensures the safety and stability of the power system, especially in industries with heavy loads such as steel, petrochemicals, and aluminum. In rail transportation, such as subways and high-speed railways, high-voltage switchgear ensures the stability and safety of the power system. High-voltage switchgear mainly consists of two parts: the cabinet and the circuit breaker. The cabinet comprises the shell, electrical components (including insulation), various mechanisms, secondary terminals, and wiring. The structure of high-voltage switchgear is generally similar, mainly divided into busbar compartment, circuit breaker compartment, secondary control compartment (instrument compartment), and feeder compartment, with steel plates generally separating these compartments. The busbar compartment is used to install and arrange the three-phase high-voltage AC busbars and connect them to the stationary contacts via branch busbars. The circuit breaker compartment is equipped with specific guide rails for the circuit breaker trolley to slide and operate. The working principle of high-voltage switchgear is to achieve the transmission, distribution, and control of the power system through the opening and closing of circuits by switching equipment. When a circuit needs to be opened, operators manually or remotely control the switching equipment to connect the circuit, thereby enabling power transmission and distribution. When a circuit fault occurs or maintenance is required, operators can disconnect the circuit or perform grounding operations using the switching equipment, ensuring the safe operation of the power system. During circuit opening and closing, phenomena such as electric arcs and overvoltages can easily occur; therefore, high-voltage switchgear needs to be equipped with appropriate protective devices, such as arc control devices, overvoltage protectors, and surge arresters, to ensure the safety of equipment and personnel.

[0003] The existing switch cabinet contains multiple electrical components, many of which are connected by cables. These cables are prone to coming loose due to tangling. The frequent opening and closing of the switch cabinet also allows dust to enter, which can easily lead to overheating and damage to the electrical components. Utility Model Content
