Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and more specifically, to a vertical spinal disconnect switch. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power sources, performing switching operations, and connecting and disconnecting low-current circuits, without arc-extinguishing capabilities. As a high-voltage switch, the disconnecting switch plays an indispensable role in the field of power switchgear. The main characteristic of a disconnecting switch is its lack of arc-extinguishing capability; it has no special arc-extinguishing device in its structure and is primarily used for isolating power sources, performing switching operations, and can also be used to open and close circuits with no or low current.

[0003] Existing disconnecting switches often lack protection when the moving and stationary contacts are disconnected, which may cause leakage. Furthermore, the adjustment of these moving contacts is generally done manually one by one, which is relatively troublesome.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this invention is to provide a vertical spinal isolating switch to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vertical spinal isolating switch includes a first side plate and a second side plate arranged parallel and symmetrically to each other. The first side plate and the second side plate are fixedly connected on one side by a spinal fixation plate. A pole post is fixedly installed on the spinal fixation plate facing the center between the first side plate and the second side plate. A contact assembly is fixedly installed at the bottom of the pole post. A mounting seat is rotatably installed on the side wall of the first side plate facing the second side plate. An assembly hole is opened on the second side plate facing the mounting seat. The contact assembly is located between the mounting seat and the assembly hole. An isolating shaft is fixedly installed on the mounting seat. The end of the isolating shaft away from the mounting seat passes through the assembly hole. The contact assembly is installed on the isolating shaft.

A grounding bar is fixedly installed on the first crossbeam along its length. A grounding stationary contact is fixedly installed on the side of the grounding bar facing the pole post. An isolation blade facing the contact assembly is fixedly installed on the second crossbeam. The number of contact assemblies, grounding stationary contacts, and isolation blades are equal and correspond one-to-one.

[0009] Furthermore, the pole includes a fixing post, the top of which has an inner cavity, and the top of the fixing post is integrally provided with an outer protective shell. An assembly block is integrally provided on the outer wall of the fixing post, and the assembly block is fixedly installed on the spinal fixation plate. An installation frame located above the inner cavity is fixedly installed inside the outer protective shell. A cam is rotatably installed on the installation frame, and the bottom of the installation frame is also connected to a connecting spine extending directly above the inner cavity.

[0010] Furthermore, symmetrical notches are provided on the sidewalls of the outer casing, and the notches are located close to the adjacent pole posts.

[0011] Furthermore, the bottom of the fixed column is provided with a through hole, which is connected to the inner cavity. The contact assembly includes a copper column, one end of which is fixedly installed in the through hole. The connecting spine is connected to the copper column via an electric wire. A moving contact is hinged to the end of the copper column located outside the through hole. An isolation connecting piece is fixedly installed on the outside of the isolation shaft.

Detailed Implementation

[0022] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0023] Please see Figure 1-6 According to an embodiment of the present invention, a vertical spinal isolating switch includes a first side plate 1 and a second side plate 2 arranged parallel and symmetrically to each other. The first side plate 1 and the second side plate 2 are fixedly connected on one side by a spinal fixation plate 3. A pole post 4 is fixedly installed on the spinal fixation plate 3 facing the center between the first side plate 1 and the second side plate 2. A contact assembly 5 is fixedly installed at the bottom of the pole post 4. A mounting seat 6 is rotatably installed on the side wall of the first side plate 1 facing the second side plate 2. An assembly hole 7 is opened on the second side plate 2, which is directly opposite to the mounting seat 6. The contact assembly 5 is located between the mounting seat 6 and the assembly hole 7. An isolating shaft 8 is fixedly installed on the mounting seat 6. The end of the isolating shaft 8 away from the mounting seat 6 passes through the assembly hole 7. The contact assembly 5 is installed on the isolating shaft 8. By rotating the isolating shaft 8, the contact assembly 5 can be indirectly adjusted.

[0024] A first crossbeam 9 and a second crossbeam 12 are installed on the side away from the spinal fixation plate 3 between the first side plate 1 and the second side plate 2. A grounding bar 10 arranged along its length is fixedly installed on the first crossbeam 9. A grounding stationary contact 11 is fixedly installed on the side of the grounding bar 10 facing the pole post 4. An isolation blade 13 facing the contact assembly 5 is fixedly installed on the second crossbeam 12. The number of contact assemblies 5, grounding stationary contacts 11, and isolation blades 13 are equal and correspond one-to-one. The position of the contact assembly 5 can be adjusted by the isolation shaft 8, thereby enabling the contact assembly 5 to contact the grounding stationary contact 11 or the isolation blade 13.

[0025] The pole post 4 includes a fixing post 14, with an inner cavity 15 inside the top of the fixing post 14. An outer protective shell 16 is integrally formed on the top of the fixing post 14, and an assembly block 17 is integrally formed on the outer wall of the fixing post 14. The assembly block 17 is fixedly installed on the spinal fixation plate 3. A mounting bracket 19 is fixedly installed inside the outer protective shell 16, located above the inner cavity 15. A cam 20 is rotatably mounted on the mounting bracket 19. The bottom of the mounting bracket 19 is also connected to a connecting spine 21 extending directly above the inner cavity 15. The wire extends into the inner cavity 15 through the connecting spine 21 and is finally connected to the contact assembly 5.

[0026] The outer casing 16 also has symmetrical notches 18 on its side wall, which are located close to the adjacent pole post 4. This arrangement allows all the cams 20 to be connected using a single shaft.

[0027] The bottom of the fixed column 14 has a through hole 22, which communicates with the inner cavity 15. The contact assembly 5 includes a copper column 23, one end of which is fixedly installed in the through hole 22. The connecting spine 21 is connected to the copper column 23 via an electric wire. A moving contact 24 is hinged to the end of the copper column 23 located outside the through hole 22. An isolation connecting piece 25 is fixedly installed on the outside of the isolation shaft 8. A connecting plate 26 is hinged to the end of the isolation connecting piece 25 away from the isolation shaft 8. The end of the connecting plate 26 away from the isolation connecting piece 25 is connected to the middle of the moving contact 24 via a connecting block 27. When the isolation shaft 8 is rotated, the isolation shaft 8 will drive the isolation connecting piece 25 to swing. The swing of the isolation connecting piece 25 will pull the connecting block 27 to move through the connecting plate 26 at its end. At this time, the connecting block 27 will drive the moving contact 24 to swing along the end of the copper column 23, so that the moving contact 24 can contact the grounding stationary contact 11 or the isolation blade 13.

[0028] Through the above-described solution of this utility model, the structure of this utility model is simple and compact, the operation is flexible, controllable and stable, and the maintenance is convenient. The structure of the disconnecting switch has been optimized, which can facilitate quick power disconnection during subsequent maintenance and repair, and can also provide leakage protection through the grounding wire, providing a safe environment for the switch cabinet.
