[0014] Compared with the prior art, the present invention provides a fast-response vacuum arc circuit breaker with the following beneficial effects: 1.

[0015] 2. The present invention uses a sealing detection vacuum device to make the connection between the scale support rod and the first cylindrical shell a snap-on connection. When the sealing detection vacuum device is found to have a fault during the maintenance process, the pressure difference is reduced, thereby reducing the pressure on the scale support rod and the T-shaped sliding rod. Then, the scale support rod and the T-shaped sliding rod can be quickly removed to check for the problem. When the problem is solved, the scale support rod and the T-shaped sliding rod can be quickly installed back, thereby reducing the time required for the maintenance process.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0022] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0023] For example 1, please refer to Figure 1-3 The present invention provides a technical solution: a fast-response vacuum arc circuit breaker, comprising a first cylindrical shell 1, a first circuit breaker 2 being fixedly connected to the interior of the first cylindrical shell 1, and a sealing detection vacuum device 3 being fixedly connected to the top of the first cylindrical shell 1; the sealing detection vacuum device 3 is used to increase the sealing effect between the first cylindrical shell 1 and the sealing detection vacuum device 3 while checking the internal air pressure of the first cylindrical shell 1, and the sealing detection vacuum device 3 comprises a scale support rod 301, the scale support rod 301 is snap-fitted to the first cylindrical shell 1, the scale support rod 301 is made of a transparent material, the outer shape of the scale support rod 301 is conical, the sliding groove on the surface of the scale support rod 301 is rectangular, the scale support rod 301 is slidably connected to the interior of the scale support rod 302, and the width of the first sliding rod 302 is consistent with the width of the sliding groove on the surface of the scale support rod 301, The surface of the scale support rod 301 is movably connected with a first rubber sealing ring 303, and the first rubber sealing ring 303 is sleeved with the first cylindrical shell 1. The end of the first sliding rod 302 away from the scale support rod 301 is fixedly connected with a T-shaped sliding rod 304, and the vertical part of the T-shaped sliding rod 304 is conical. The conical design of the vertical part of the T-shaped sliding rod 304 is used to increase the pressure generated by the pressure difference to increase the sealing effect of the T-shaped sliding rod 304 and the first cylindrical shell 1. The cylindrical surface of the T-shaped sliding rod 304 is movably connected with a first compression spring 305, and the first compression spring 305 is located at the top of the second rubber sealing ring 306. The cylindrical surface of the T-shaped sliding rod 304 is movably connected with a second rubber sealing ring 306, and the second rubber sealing ring 306 is sleeved with the first cylindrical shell 1. The surface of the first cylindrical shell 1 is fixedly connected with an acceleration sealing device 4.

[0024] The working principle of the first embodiment is as follows: the pressure difference between the inside of the first cylindrical shell 1 and the outside world causes the T-shaped sliding rod 304 and the scale support rod 301 to be subjected to pressure in the direction close to the first cylindrical shell 1, and as the pressure difference increases, the pressure on the T-shaped sliding rod 304 and the scale support rod 301 also increases, and then the pressure is transmitted to the first compression spring 305 through the T-shaped sliding rod 304. When the pressure reaches the compression limit of the first compression spring 305, the first compression spring 305 begins to compress. According to the size of the pressure, the compression degree of the first compression spring 305 is also different. During the compression of the first compression spring 305, the T-shaped sliding rod 304 moves in the direction close to the first cylindrical shell 1. Since the vertical part of the T-shaped sliding rod 304 is conical, as the T-shaped sliding rod 304 moves, the T-shaped The pressure exerted by the sliding rod 304 on the first rubber sealing ring 303 will also increase, and the first sliding rod 302 will be driven to move inside the scale support rod 301 during the movement of the T-shaped sliding rod 304. When the internal air pressure inside the first cylindrical shell 1 reaches the vacuum condition, the first sliding rod 302 will also stay at a specific position inside the scale support rod 301. During the maintenance process, if it is found that the sealing detection vacuum device 3 fails, the pressure on the T-shaped sliding rod 304 and the scale support rod 301 can be reduced by reducing the pressure difference, and then the T-shaped sliding rod 304 and the scale support rod 301 can be pulled out. When the T-shaped sliding rod 304 and the scale support rod 301 need to be installed back, the T-shaped sliding rod 304 and the scale support rod 301 are reinserted into the first cylindrical shell 1, and then the pressure difference between the first cylindrical shell 1 and the outside world is increased again.

[0026] The working principle of the second embodiment is as follows: the fan blades on the output shaft are driven to rotate by the first airflow generating device 407, and the circular support plate 4063 is driven to rotate in the process, and then the circular support plate 4063 drives the impact block 4064 to rotate inside the annular slide groove, and during the rotation process, the impact block 4064 applies a thrust to the top rod of the rotating push rod device 4065, so that the top rod of the rotating push rod device 4065 contacts the limit block 403, and then the first telescopic device 4066 drives the circular support plate 4063 to retract, and the circular support plate 4063 drives the impact block 4064 to retract, so that the impact block 4064 does not contact the rotating push rod device 4065 during the rotation process. Contact, the top rod of the rotating push rod device 4065 pushes up the upper cover 402, so that a gap is generated between the upper cover 402 and the second cylindrical shell 401, and then as the first airflow generating device 407 rotates, the airflow is accelerated to enter the interior of the first cylindrical shell 1. When it is necessary to close the gap between the upper cover 402 and the second cylindrical shell 401, the first airflow generating device 407 is rotated in the opposite direction, and then the circular support plate 4063 is extended by the first telescopic device 4066, and the circular support plate 4063 drives the impact block 4064 to extend, so that the impact block 4064 contacts the rotating push rod device 4065, and the rotating push rod device 4065 leaves the limit block 403.
