Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breakers, and more particularly to an intelligent vacuum circuit breaker. Background Technology

[0002] Vacuum circuit breakers are named for their high-vacuum arc-extinguishing medium and the high-vacuum insulation medium in the contact gap after arc extinguishing. They are characterized by their small size, light weight, suitability for frequent operation, and maintenance-free arc extinguishing, making them widely used in power distribution networks. Vacuum circuit breakers are indoor power distribution devices in 3-10kV, 50Hz three-phase AC systems, used in industrial and mining enterprises, power plants, and substations for the protection and control of electrical equipment. They are particularly suitable for applications requiring oil-free operation, minimal maintenance, and frequent operation. Circuit breakers can be installed in medium-voltage switchgear, double-layer switchgear, and fixed switchgear for the control and protection of high-voltage electrical equipment.

[0003] Traditional structures typically lack physical isolation or interlocking devices, allowing operators to directly access operating components. This can easily lead to misoperation due to negligence or misjudgment, such as accidentally pressing the trip button when closing the circuit breaker, causing an electrical accident. Traditional structures also have insufficient sealing, allowing dust, moisture, and corrosive gases to easily penetrate the interior, leading to decreased insulation performance or mechanical jamming. Furthermore, in high-temperature, high-humidity, or strong electromagnetic interference environments, traditional structures are prone to failure due to material aging or electromagnetic interference.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example: This example provides an intelligent vacuum circuit breaker, see [link to example]. Figures 1-4 Specifically, it includes a protective frame 1, a vacuum circuit breaker body 2, a protective plate 3, and a removable assembly; a ventilation opening 5 is provided on one side of the protective frame 1; the vacuum circuit breaker body 2 passes through the top of the protective frame 1, and the vacuum circuit breaker body 2 is provided with a closing pull ring 6, a opening pull ring 7, an emergency opening pull ring 8, and an opening / closing indicator 9; the protective plate 3 is fitted into the protective frame 1; the removable assembly is located inside the protective plate 3, and the removable assembly includes a limiting mechanism for fixing the protective plate 3 and a transmission mechanism for driving the limiting mechanism to move, the limiting mechanism including a limiting plate 16; both sets of the limiting plates 16 are slidably mounted on the protective plate 3 and engaged with the protective frame 1, and the protective frame 1 has a strip groove for the insertion of the limiting plates 16.

[0026] In the specific implementation process, such as Figure 4 As shown, the limiting mechanism further includes a mounting frame 12 and a sliding plate 15; two sets of mounting frames 12 are respectively disposed on the inner walls of both sides of the protective plate 3; both sets of sliding plates 15 are slidably disposed on the mounting frame 12, and the mounting frame 12 is provided with a guide unit for limiting the movement of the sliding plate 15; the limiting plate 16 is disposed on the mounting frame 12; the guide unit includes a guide post 13 and a spring 14; the guide post 13 is disposed on the mounting frame 12 and passes through the two sets of sliding plates 15; the spring 14 is connected to the two sets of sliding plates 15;

[0027] When it is necessary to fix the protective plate 3, the sliding plate 15 and the limiting plate 16 can be slid on the mounting frame 12 and the guide post 13 by operating the transmission mechanism until the limiting plate 16 passes through the protective plate 3 and inserts into the protective frame 1, so that the protective plate 3 can be installed and fixed, thereby improving the protection of the operating components on the vacuum circuit breaker body 2.

[0028] In the specific implementation process, such as Figure 4As shown, the transmission mechanism includes a connecting column 10, a guide plate 11, and a transmission plate 17; the connecting column 10 rotates through the protective plate 3; the guide plate 11 is rotatably disposed inside the protective plate 3 and connected to the connecting column 10; the two ends of the transmission plate 17 are rotatably connected to the guide plate 11 and the sliding plate 15, respectively, and the transmission plate 17 is provided with two sets; one end of the connecting column 10 is provided with a rotating block 4 that rotates it, and the rotating block 4 is located outside the protective plate 3;

[0029] The connecting column 10 and the guide plate 11 are rotated by manually operating the rotating block 4, which in turn drives the transmission plate 17 to rotate, thereby guiding the sliding plate 15 and the limiting plate 16 to adjust their position on the mounting frame 12, thus enabling the quick installation and disassembly of the protective plate 3.

[0030] Specifically, the working principle and operation method of this utility model are as follows:

[0031] In use, the position of the sliding plate 15 and the limiting plate 16 can be adjusted under the action of the rotating block 4. When the protective plate 3 needs to be positioned, the limiting plate 16 can be inserted into the protective frame 1. When the protective plate 3 needs to be removed, the limiting plate 16 can be retracted. The protective plate 3 can shield external pollutants such as dust, moisture, and corrosive gases, preventing them from entering the vacuum circuit breaker body 2 and reducing the risk of insulation performance degradation or jamming of operating parts.
