Embodiment Construction
[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0025] see Figure 1-Figure 7 As shown, the present invention provides a solid-sealed pole type outlet bushing, which includes a conductor rod 1, a vacuum interrupter 4 connected to one end of the conductor rod 1, and an insulation cast on the outside of the conductor rod 1 and the vacuum interrupter 4. Sleeve 3; the conductor rod 1 is a solid straight rod, and the conductor rod 1 is collinear with the central axis of the vacuum interrupter 4; the end of the co...

The solid-sealed polar pole type outgoing line sleeve comprises a conductor rod, a vacuum arc-extinguishing chamber connected with one end of the conductor rod, and an insulating sleeve poured on theouter sides of the conductor rod and the vacuum arc-extinguishing chamber, the conductor rod and the central axis of the vacuum arc-extinguishing chamber are collinear. One end, far away from the vacuum arc-extinguishing chamber, of the conductor rod and one end, far away from the conductor rod, of the vacuum arc-extinguishing chamber extend out of the outer side of the insulating sleeve, and oneend, far away from the vacuum arc-extinguishing chamber, of the conductor rod is provided with a wire outlet terminal; the outer side of the insulating sleeve far away from one end of the vacuum arc-extinguishing chamber is sleeved with an umbrella skirt, and the surface of the insulating sleeve located outside the vacuum arc-extinguishing chamber is provided with a plurality of annular lines distributed at intervals. According to the invention, the number of detachable parts is small, the reliability is high, the product structure is simplified, and miniaturization of the switch cabinet is facilitated; in addition, the manufacturing cost is reduced, and the percent of pass of products is increased.
Description
technical field [0001] The invention relates to the technical field of vacuum switches, in particular to a solid-sealed pole type outlet sleeve. Background technique [0002] In the field of medium-voltage power transmission, especially in the 12kV class, vacuum circuit breakers are widely used. The wide application of vacuum circuit breakers is inseparable from the continuous progress of vacuum circuit breaker technology, the most important of which is the technological progress of solid-sealed poles. The pole insulation of vacuum circuit breakers has gone through three stages: air insulation, composite insulation, and solid-seal insulation. The function of the solid-sealed pole is to extinguish the arc through the vacuum interrupter, so as to break the overload current and protect the electrical equipment. The structure of the currently used embedded pole is relatively complex, and the manufacturing is difficult and costly. Therefore, it is necessary to design a new type...
