Abstract
The invention relates to a solid-sealed vacuum circuit breaker for a high voltage alternating-current generator. The product is compared with the existing open type vacuum circuit breaker, and the galvanic circle is completely sealed inside epoxy resin without being influenced by the environment, so that the insulating property is extremely high. The design of a cast pole has two obvious characteristics that a major loop inside the pole adopts hat type soft connection; and jet self-cooling U-typed ventilation tunnels are arranged on both sides of the pole, so that the temperature rise value satisfies national standard when the running current is 5000A. The product can replace the presently running open type vacuum circuit breaker so that more safe and reliable running of the generator is ensured.
Description
Technical field
The present invention relates to a kind of high-voltage alternating current generator solid sealing type vacuum circuit breaker.
Background technology
Existing generator is the pole unenclosed construction with vacuum circuit-breaker, and namely major loop is open in atmosphere, polluted by dust, moisture, and insulation property reduce, and finally cause insulation fault, destroys safe operation of power plant.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of high-voltage alternating current generator solid sealing type vacuum circuit breaker that makes the operation of high-voltage generator safety and reliability ground.
Complete skill scheme of the present invention is, a kind of high-voltage alternating current generator solid sealing type vacuum circuit breaker, comprise with as a whole vacuum interrupter and the upper and lower electric-conductor of poured with epoxy resin, be provided with the hat type connector on the galvanic circle of described pole, described hat type connector comprises upper connector and lower connector.
The both sides of described pole are provided with the self cooling U-shaped air duct of injecting type.
The rated current 5000A of described pole, drop-out current 50kA.
Therefore the present invention has compared following beneficial effect with present technology:
High-voltage alternating current generator of the present invention solid sealing type vacuum circuit breaker vacuum interrupter, it is as a whole that electric-conductor is all used poured with epoxy resin up and down, namely becomes solid envelope shape galvanic circle, avoids dust, moisture pollution, guaranteed the insulation property of major loop.The soft link of hat type is adopted in the pole galvanic circle, thereby significantly reduces loop resistance, reduces heating power.The pole both sides are designed with the self cooling U-shaped air duct of injecting type, and the self cooling effect of utilizing smokestack effect heat outwards to spray reduces thermal accumlation in the pole, has reduced temperature rise value.
Description of drawings
Accompanying drawing described herein is used to provide a further understanding of the present invention, consists of the application's a part, does not consist of to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment 1:
A kind of high-voltage alternating current generator solid sealing type vacuum circuit breaker of the present embodiment, comprise with as a whole vacuum interrupter 1 and the upper and lower electric-conductor of poured with epoxy resin, be provided with the hat type connector on the galvanic circle of pole, the hat type connector comprises upper connector and lower connector, the both sides of pole are provided with the self cooling U-shaped air duct of injecting type, the rated current 5000A of pole, drop-out current 50kA.
Therefore, high-voltage alternating current generator of the present invention solid sealing type vacuum circuit breaker vacuum interrupter, it is as a whole that electric-conductor is all used poured with epoxy resin up and down, namely becomes solid envelope shape galvanic circle, avoids dust, moisture pollution, guaranteed the insulation property of major loop.The soft link of hat type is adopted in the pole galvanic circle, thereby significantly reduces loop resistance, reduces heating power.The pole both sides are designed with the self cooling U-shaped air duct of injecting type, and the self cooling effect of utilizing smokestack effect heat outwards to spray reduces thermal accumlation in the pole, has reduced temperature rise value.
The above technical scheme that the embodiment of the invention is provided is described in detail, used specific case herein principle and the execution mode of the embodiment of the invention are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, all will change on embodiment and range of application, in sum, this description should not be construed as limitation of the present invention.
