Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an outdoor AC high-voltage vacuum circuit breaker. Background Art

[0002] High-voltage vacuum circuit breakers are the main power control equipment in substations. They have arc extinguishing characteristics. When the system is operating normally, they can cut off and connect the no-load and load currents of the lines and various electrical equipment. When a system fault occurs, it cooperates with the relay protection to quickly cut off the fault current to prevent the scope of the accident from expanding.

[0003] However, in the prior art high-voltage vacuum circuit breaker, such as the prior art with publication number CN117810020B, it is relatively complicated to obtain power from the circuit breaker. Utility Model Content

[0004] The purpose of the present utility model is to provide an outdoor AC high-voltage vacuum circuit breaker to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: an outdoor AC high-voltage vacuum circuit breaker, comprising a base, on which an isolating knife switch, a sealed pole and a knife holder are provided; the base is also provided with a mounting plate, and a capacitor is provided on the mounting plate; the upper end of the capacitor is connected to the sealed pole, and the bottom of the capacitor is connected to an aviation socket provided on the base via a provided wire.

[0006] As a preferred technical solution of the present invention: the wire is fixed to the base via a fastener.

[0007] As a preferred technical solution of the present invention: the isolation knife gate includes a first clamping plate and a second clamping plate, and is connected to a provided nut after a provided bolt passes through the first clamping plate and the second clamping plate.

[0008] As a preferred technical solution of the present invention: a spring is further provided between the first clamping plate and the bolt, and the spring is sleeved outside the bolt.

[0009] As a preferred technical solution of the present invention: one end of the spring away from the first clamping plate is connected to the bolt via a provided cover plate.

[0010] As a preferred technical solution of the present invention: protrusions are provided on the facing surfaces of the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are in contact with the tool holder through the protrusions.

[0011] By adopting the above technical solution, the beneficial effect of the utility model is as follows: since a mounting plate is directly provided on the base and a capacitor is mounted on the mounting plate, and the upper end of the capacitor is electrically connected to the sealed pole, and the bottom of the capacitor is connected to the aviation socket through a wire, when the external plug is connected to the aviation socket, the power supply can be led out. Based on this, the device has the advantage of convenient power removal while ensuring circuit safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present invention are described in detail below, and 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, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0020] See also Figure 1-5The utility model provides an embodiment: an outdoor AC high-voltage vacuum circuit breaker, comprising a base 1, on which an isolating knife switch 5, a sealed pole 6 and a knife seat 4 are provided; the base 1 is also provided with a mounting plate 2, and a capacitor 3 is provided on the mounting plate 2; the upper end of the capacitor 3 is connected to the sealed pole 6, and the bottom of the capacitor 3 is connected to the aviation socket 7 provided on the base 1 through a provided wire 9.

[0021] In summary, since mounting plate 2 is directly mounted on base 1, capacitor 3 is mounted on mounting plate 2, and the upper end of capacitor 3 is electrically connected to encapsulated pole 6, for example, via a wire or conductive plate; and the bottom of capacitor 3 is connected to aviation socket 7 via wire 9, power can be drawn out when an external plug is connected to aviation socket 7. Based on this, the device not only ensures circuit safety but also has the advantage of convenient power removal. Furthermore, although the device has a simple structure, current vacuum circuit breakers do not have the function of drawing power.

[0022] Furthermore, since the wire 9 is fixed to the base 1 by the provided fastener 8, the wire 9 and the base 1 are relatively fixed, thereby preventing the wire 9 from swinging with the wind.

[0023] Based on the above scheme, the isolation knife gate 5 includes a first clamping plate 10 and a second clamping plate 11, and is connected to a nut 12 after passing through the first clamping plate 10 and the second clamping plate 11 through a provided bolt 14, thereby making the isolation knife gate 5 easy to assemble.

[0024] Furthermore, since a spring 13 is provided between the first clamping plate 10 and the bolt 14, and the spring 13 is sleeved outside the bolt 14, the elastic force of the spring 13 can be used to enable the two clamping plates to be reliably clamped on the knife holder 4, avoiding poor contact.

[0025] Furthermore, since the end of the spring 13 away from the first clamping plate 10 is connected to the bolt 14 through the provided cover plate 15, the cover plate 15 can be used to cover one end of the spring 13 to improve the stability of the spring 13 during operation.

[0026] In addition, since the first clamping plate 10 and the second clamping plate 11 are provided with protrusions 16 on the facing surfaces, and contact the knife seat 4 through the protrusions 16, the isolation knife gate 5 and the knife seat 4 are more reliable. At the same time, by gold or silver plating on the outer wall of the protrusion 16, the spark phenomenon of the isolation knife gate 5 when in contact with the knife seat 4 is reduced, thereby extending the service life of the knife seat 4 and the isolation knife gate 5.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
