Description

Technical Field

[0001] This utility model relates to an electrical disconnect switch, specifically a C-GIS epoxy integrated three-position disconnect switch. Background Technology

[0002] Many electrical components are used in C-GIS and gas-insulated switchgear to ensure stable operation of electrical equipment. Three-position disconnect switches are commonly used in gas-insulated switchgear. A three-position disconnect switch integrates a disconnect switch and a grounding switch. It is one of the core components of gas-insulated switchgear and has a wide range of applications, fulfilling the isolation and grounding functions of the gas-insulated switchgear in subsequent operations.

[0003] The prior art CN201721058484.0 discloses a three-position disconnect switch and circuit breaker. This utility model discloses a three-position disconnect switch and circuit breaker, including a safety door. The safety door is installed at the front of the housing. An open / close position indicator light is provided in front of the safety door and near the upper right corner. An open button is provided below the open button. An anti-misoperation knob is provided below the open button. A close button is provided to the left of the anti-misoperation knob. The three-position disconnect switch is equipped with both electric control and manual control operations. In this way, when the electric control fails, manual control can be used in an emergency, enabling the three-position disconnect switch to cope with various faults to a greater extent.

[0004] In the existing technology, a cooling fan is installed inside the three-position disconnect switch. This allows the cooling fan to continuously blow air into the interior of the three-position disconnect switch, thereby reducing the internal temperature in a timely manner. However, disconnect switches operating in gas-filled cabinets are prone to problems with insufficient bottom support. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a C-GIS epoxy integrated three-position disconnect switch.

[0006] This utility model is achieved using the following technical solution: a C-GIS epoxy integrated three-position disconnect switch, which is provided with a stationary contact, the stationary contact being divided into a front stationary contact and a rear stationary contact, and an intermediate stationary contact being provided between the front stationary contact and the rear stationary contact. The front stationary contact, the rear stationary contact, and the intermediate stationary contact are concentric. A bottom support is provided at the bottom of the rear stationary contact, and a bracket is provided on the bottom support. The bracket is located at the bottom of the intermediate stationary contact. A bottom lifting component is provided on the bottom support, and the bottom lifting component is a lifting plate. An assembly component is provided on one side of the lifting plate.

[0007] The lifting plate is provided with heat dissipation components, which are heat dissipation holes, and the heat dissipation holes are evenly distributed on the lifting plate.

[0008] The outer surfaces of the front stationary contact, rear stationary contact, and middle stationary contact are provided with a protective layer, which is an epoxy resin protective layer.

[0009] A spacer is provided between the rear stationary contact and the middle stationary contact. The spacer is a spacer break, and an epoxy resin protective layer is provided at the spacer break.

[0010] The assembly component is an assembly stand, which is welded and fixed to the support plate. Assembly holes are provided on the assembly stand, and assembly bolts are installed in the assembly holes.

[0011] Compared to existing technologies, this invention features a front stationary contact, a rear stationary contact, and a middle stationary contact on the disconnector switch with consistent concentricity. This ensures more accurate installation of these contacts. Furthermore, an epoxy resin protective layer is applied to the front, rear, and middle stationary contacts, providing excellent external protection and preventing them from operating at excessively high pressure. Support plates are located at the bottom of each contact, and the cooperation between the support plates and the bottom bracket provides support to the bottom of these contacts, meeting their operational requirements.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] A C-GIS epoxy integrated three-position disconnector is provided, which is equipped with stationary contacts, namely a front stationary contact 1 and a rear stationary contact 2. An intermediate stationary contact 3 is provided between the front stationary contact 1 and the rear stationary contact 2. The front stationary contact 1, the rear stationary contact 2 and the intermediate stationary contact 3 are concentric. A bottom support 4 is provided at the bottom of the rear stationary contact 2. A bracket 5 is provided on the bottom support 4. The bracket 5 is located at the bottom of the intermediate stationary contact 3. A bottom lifting component is provided on the bottom support 4. The bottom lifting component is a lifting plate 6. An assembly component is provided on one side of the lifting plate 6.

[0018] To ensure proper assembly and support of the disconnector switch within the gas-filled cabinet, a bottom support 4 can be installed at the bottom of the rear stationary contact 2. A bracket 5 is mounted on the bottom support 4, providing support to the bottom of the rear stationary contact. Simultaneously, to support the stationary contact as a whole, a support plate 6 can be installed at the bottom of the stationary contact. The support plate 6 effectively supports the stationary contact. A heat dissipation component, namely heat dissipation holes 7, is installed on the support plate 6. Since heat is dissipated during the operation of the stationary contact in the disconnector switch, this heat dissipation component facilitates heat dissipation and flow.

[0019] A protective layer is provided on the outer surface of the front stationary contact 1, the rear stationary contact 2, and the middle stationary contact 3. The protective layer is made of epoxy resin. A spacer is provided between the rear stationary contact 2 and the middle stationary contact 3. The spacer is a spacer break 8. An epoxy resin protective layer is provided on the spacer break 8. An epoxy resin protective layer is provided on both the stationary contact and the spacer break. The epoxy resin protective layer can effectively improve the pressure resistance of the stationary contact.

[0020] To further strengthen the bottom support of the front stationary contact 1, rear stationary contact 2, and middle stationary contact 3, a support plate is provided at the bottom of the front stationary contact 1, rear stationary contact 2, and middle stationary contact 3. This allows for further assembly of the support plate 6 and the gas-filled switchgear. Assembly components can be used, and generally, the assembly component is an assembly stand plate 9. The assembly stand plate 9 and the support plate 6 are welded together. Assembly holes are provided on the assembly stand plate 9, and assembly bolts 10 are installed in the assembly holes. The assembly bolts allow for a more stable assembly of the disconnect switch and the gas-filled switchgear.

[0021] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
