Description

Technical Field

[0001] The utility model relates to a high-voltage isolating switch structure of a ring network cabinet, belonging to the technical field of isolating switches. Background Art

[0002] Isolators are essential devices used in power systems. Their primary function is to disconnect circuits and completely isolate the power supply, ensuring safe operation during power outages. They are commonly used during maintenance and repair of electrical equipment to effectively prevent electric shock and damage, ensuring the safety of both operators and equipment. Simple and reliable, easy to operate, and durable, isolators play a vital role in the management and safety control of power supply systems.

[0003] A Chinese patent application (publication number: CN 207818456 U) discloses a disconnector for a high-voltage ring network cabinet. The disconnector comprises a frame, two cylinders disposed above the frame, a cylinder disposed within the cylinders, a through slot disposed above the frame on one side of the cylinders, two second mounting plates disposed within the frame, a movable rod disposed between the second mounting plates, a mounting rod disposed on the second mounting plates corresponding to the through slots, and the upper ends of the mounting rods extending through the through slots. One end of the fixed rod extends through one side of the cylinders and is disposed within the fixed slots. An insulator is disposed above the cylinders, a locking plate disposed on one contact seat, a contact spring disposed on one side of the contact blade, a limit plate disposed at one end of the movable rod, and a spring sleeved on the movable rod between the limit plate and the second mounting plate. This device has a simple structure and is easy to operate, making it easier for workers to maintain or repair damaged disconnectors, while improving work efficiency and reducing repair time.

[0004] The above patent operates the movable rod by pulling the handle to move the fixed rod out of the fixed slot and remove the isolating switch, thereby facilitating maintenance and repair. However, the fixing structure of the above isolating switch is relatively simple and there is no corresponding locking assembly. Personnel who are not doing the corresponding work can operate the movable rod by pulling the handle to move the fixed rod out of the fixed slot and remove the isolating switch. The isolating switch is an indispensable and important component in the power system. It is mainly used to switch circuits under no-load conditions and provide safety guarantees for maintenance work. The design and installation of the isolating switch is to ensure the safe operation of the power system. Random removal may cause damage to the equipment, such as insulator rupture, contact heating, and even short circuit, which reduces safety. In addition, fatigue cracks may occur in the spring during long-term repeated loading and unloading, eventually causing it to break and become unusable, reducing the practicality of the equipment.

[0005] Therefore, a high-voltage disconnect switch structure of a ring main unit is proposed. Utility Model Content
