Description

Technical Field

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

[0002] In the existing indoor high-voltage vacuum circuit breakers, the sealed pole is fixed on the support frame through its bottom, such as the patented product with patent number: CN105070582A; although the above method can also complete the fixation of the sealed pole, the sealed poles in the above products are all fixed on the support frame at a single point. Therefore, when the sealed pole is maintained and serviced, when the chassis vehicle pulls out the support frame, the sealed pole is easily bent toward the primary high-voltage joint during the separation process from the primary high-voltage joint due to the single-point fixation. Over time, it is easy to cause the sealed pole to shake on the support frame. For this reason, it is usually necessary to set the bottom of the sealed pole into a square structure to expand the contact area between the sealed pole and the support frame. However, the sealed pole is cast with insulating material, so the bottom of the sealed pole is different from the body part in shape, resulting in great processing difficulty, more materials, and high requirements for sealing technology during processing. Utility Model Content

[0003] The purpose of the utility model is to provide an indoor high-voltage vacuum circuit breaker to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an indoor high-voltage vacuum circuit breaker, comprising a chassis vehicle, a support frame installed on the chassis vehicle and a sealed pole installed on the support frame; a connector is also provided between the sealed pole and the support frame, and a connecting column is also provided at the bottom of the sealed pole, and the connecting column passes through the support frame and is connected to a first fastener; the connector comprises a first clamping plate sleeved on one side of the sealed pole, and the first clamping plate is connected to a second clamping plate provided on the other side of the sealed pole; the first clamping plate is connected to a connecting seat provided on the support frame through a second fastener provided.

[0005] As a preferred technical solution of the utility model: a rubber pad is also provided on the support frame, and the rubber pad is placed at the connection between the sealed pole and the support frame.

[0006] As a preferred technical solution of the utility model: the first clamping plate is movably connected to the second clamping plate, and after the two ends of the second clamping plate are inserted into the first clamping plate, the first clamping plate and the second clamping plate are fixed together by means of provided latches.

[0007] As a preferred technical solution of the utility model: a threaded seat consistent with the structure of the connecting seat is also provided on the first clamping plate; wherein one end of the second fastener is threadedly matched with the connecting seat, and the other side of the second fastener is threadedly matched with the threaded seat.

[0008] By adopting the above technical solution, the beneficial effect of the utility model is as follows: after the bottom of the sealed pole is installed on the support frame and the sealed pole is fixed with fasteners, the connector is sleeved on the outside of the sealed pole to further fix the sealed pole. Based on this, while ensuring that the sealed pole works stably and reliably, the connection method of the connector is simple and convenient to solve the shaking of the sealed pole during the pulling process. Since the sealed pole is fixed with a connector, the upper and lower structures of the sealed pole can be unified, thereby reducing the difficulty of processing the sealed pole and saving materials.

[0014] Embodiments of the present utility model 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 utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, 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 utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0015] See also Figure 1-4 The utility model provides an embodiment: an indoor high-voltage vacuum circuit breaker, comprising a chassis vehicle 1, a support frame 5 installed on the chassis vehicle 1, and a sealed pole 2 installed on the support frame 5; a connector 3 is also provided between the sealed pole 2 and the support frame 5, and a connecting column 8 is also provided at the bottom of the sealed pole 2, and the connecting column 8 passes through the support frame 5 and is connected with a first fastener 7; the connector 3 comprises a first clamping plate 30 sleeved on one side of the sealed pole 2, and the first clamping plate 30 is connected to a second clamping plate 31 provided on the other side of the sealed pole 2; the first clamping plate 30 is connected to a connecting seat 4 provided on the support frame 5 through a second fastener 33 provided.

[0016] In summary, after the bottom of the sealed pole 2 is installed on the support frame 5 and the sealed pole 2 is fixed with the first fastener 7, the connector 3 is sleeved on the outside of the sealed pole 2 to further fix the sealed pole 2. Based on this, while ensuring that the sealed pole 2 works stably and reliably, the connection method of the connector 3 is simple and convenient to solve the shaking of the sealed pole during the pulling process. Since the sealed pole 2 is fixed by the connector 3, the upper and lower structures of the sealed pole 2 can be unified to reduce the processing difficulty of the sealed pole 2 and save materials.

[0017] In addition, the first clamping plate 30 and the second clamping plate 31 cooperate with each other to simplify the connection method between the connector 3 and the sealed pole 2. At the same time, the second clamping plate 31 is preferably made of elastic rubber material, so the second clamping plate 31 can be used to absorb the vibration generated in the arc extinguishing chamber; at the same time, the first clamping plate 30 is preferably made of brass, so it can absorb the heat inside the arc extinguishing chamber to enhance the heat dissipation capacity of the device.

[0018] Specifically, the first clamping plate 30 is movably connected to the second clamping plate 31, and after the two ends of the second clamping plate 31 are inserted into the first clamping plate 30, the first clamping plate 30 and the second clamping plate 31 are fixed together by using the provided pins 32. Therefore, the assembly of the two clamping plates can be completed by inserting the pins 32 into the connection between the two clamping plates; conversely, the two clamping plates can be separated by pulling out the pins 32, so that the disassembly and assembly of the two clamping plates is simple and convenient.

[0019] Furthermore, since the first clamping plate 30 is also provided with a threaded seat 34 having the same structure as the connecting seat 4, one end of the second fastener 33 is threadedly engaged with the connecting seat 4, and the other side of the second fastener 33 is threadedly engaged with the threaded seat 34. Therefore, tightening the second fastener 33 tightens the sealed pole 2 on the support frame 5 to ensure the stability of the sealed pole 2 after being connected to the support frame 5.

[0020] Furthermore, since a rubber pad 6 is also provided on the support frame 5, and the rubber pad 6 is padded at the connection between the sealed pole 2 and the support frame 5, the rubber pad 6 can be used to achieve sealing at the connection between the sealed pole 2 and the support frame 5 while also preventing the sealed pole 2 from directly contacting the support frame 5, which would cause the sealed pole 2 to wear or crack at the bottom due to shaking. In particular, when the sealed pole 2 is made of ceramic material, the provision of the rubber pad 6 can extend the service life of the sealed pole 2.

[0021] 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. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
