Description

Technical Field

[0001] This utility model relates to the field of electrical technology, specifically to high-voltage circuit breakers. Background Technology

[0002] The high-voltage circuit breaker includes a high-voltage circuit breaker body, which in turn includes a mounting base. A support column is located on the mounting base, and electrodes are mounted on the support column. The electrodes include two electrodes: a first electrode and a second electrode. An operating lever connected to an operating handle is also mounted on the support column. A contact blade is connected to one end of the first electrode via a first hinge shaft, and the operating lever is connected to the middle of the contact blade via a second hinge shaft. Operating the handle, and moving the operating lever, allows the other end of the contact blade to contact or separate from the second electrode, thus opening or closing the circuit breaker. The first electrode, the second electrode, the operating lever, and the contact blade form an isolating switch.

[0003] In existing technologies, the operating rods, contact blades, and electrodes of high-voltage circuit breakers are all exposed. These components are prone to oxidation and contamination, which affects their service life. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a high-voltage circuit breaker whose components, such as the operating lever, contact blade, and electrodes, are less prone to oxidation and contamination, thus extending their service life—a high-voltage circuit breaker that is completely enclosed.

[0005] The technical solution of this utility model is as follows: a high-voltage circuit breaker with a fully enclosed isolation mechanism includes a high-voltage circuit breaker body, which in turn includes a mounting base. A support column is mounted on the mounting base, and electrodes are mounted on the support column. The electrodes include two electrodes: a first electrode and a second electrode. An operating lever connected to an operating handle is also mounted on the support column. A contact blade is connected to one end of the first electrode via a first hinge shaft. The operating lever is also connected to the middle of the contact blade via a second hinge shaft. Operating the handle and moving the operating lever allows the other end of the contact blade to contact or separate from the second electrode, thus opening or closing the circuit breaker. The first electrode, the second electrode, the operating lever, and the contact blade form an isolating switch. The feature is that a protective cover is installed around the operating lever, the contact blade, and the electrodes, forming a sealed structure for the operating lever, the contact blade, and the electrodes.

[0006] Furthermore, the protective cover is made of a transparent material plate.

[0007] Furthermore, the protective cover has surrounding edges and side panels filled on the edges, the edges being made of epoxy resin and the side panels being made of a transparent material sheet.

[0008] The beneficial effects of this utility model are: such a high-voltage circuit breaker has the advantages that components such as the operating rod, contact blade, and electrodes are not easily oxidized or contaminated. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 , 2 As shown in Figures 3 and 4, a fully enclosed high-voltage circuit breaker with disconnecting switch includes a high-voltage circuit breaker body, which in turn includes a mounting base 1. A support column 2 is mounted on the mounting base, and electrodes 3 are mounted on the support column. The electrodes include two electrodes: a first electrode 31 and a second electrode 32. An operating lever 5 connected to an operating handle 4 is also mounted on the support column. A contact blade 6 is connected to one end of the first electrode via a first hinge shaft 71. The operating lever 5 is also connected to the middle of the contact blade 6 via a second hinge shaft 72. Operating the handle, and moving the operating lever, allows the other end of the contact blade to contact or separate from the second electrode, thus opening or closing the circuit breaker. The first electrode, the second electrode, the operating lever, and the contact blade form a disconnecting switch. The characteristic feature is that a protective cover 8 is installed around the operating lever, the contact blade, and the electrodes, forming a sealed structure for the operating lever, the contact blade, and the electrodes.

[0016] This invention achieves its purpose by providing protective covers for the control lever, contact blade, and electrodes, thereby reducing the exposure of these components, minimizing their chance of oxidation, and reducing external dust pollution.

[0017] The connection relationship between the control lever, the contact blade, and the electrode is the connection relationship in the prior art.

[0018] Furthermore, the protective cover is made of a transparent material plate.

[0019] This design also has the advantage of facilitating the observation of the working status of the stent.

[0020] For example, the transparent material mentioned is plexiglass, etc.

[0021] Furthermore, the protective cover has a surrounding edge 81 and a side panel 82 filled on the edge, the edge being made of epoxy resin and the side panel being made of a transparent material plate.

[0022] This design also ensures the sturdiness of the protective cover, making it durable.

Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
