Embodiment Construction

[0020] Now in conjunction with accompanying drawing, the present invention will be further described.

[0021] Such as Figure 1~4 As shown, the main body of the combined solid-sealed pole is an insulating cylinder 1, and the insulating cylinder is divided into upper and lower layers of chambers arranged in parallel and separated from each other, namely the upper chamber 101, the lower chamber 102, and the upper and lower chambers The right ends of each are open, and the open ends are hermetically connected to the sealing cover 19. The internal structure of the combined solid-sealed pole is specifically: a bearing seat 9 and an outlet seat 8 are embedded in the left end of the upper chamber, the bearing seat is fixed with the outlet seat by screws, and a deep groove ball bearing 10 is arranged in the bearing seat. The middle part of the upper chamber is embedded with a pair of static conductive seats arranged at intervals, which are the static conductive seat 3 at the left en...

Abstract

The invention relates to a combined solid encapsulated pole and a working principle thereof. The combined solid encapsulated pole comprises an insulating cylinder with an upper cavity and a lower cavity, wherein one end of the insulating cylinder is connected to a seal cover. An outgoing line base is arranged at the left end inside the upper cavity, a pair of static conducting bases which are arranged at intervals and connected with each other are arranged in the middle, and a grounding base is arranged at the right end inside the upper cavity. The static conducting base at the left end is partially embedded in the left end inside the lower cavity. A screw rod for rotary positioning is arranged in the upper cavity, one end of the screw rod extends out of the seal cover, the screw rod is in threaded connection with a dynamic touch sleeve which is in contact match with the outgoing line base, the static conducting bases, and the grounding base and forms three conducting stations. A vacuum arc-extinguishing chamber is arranged in the lower cavity, the static contact of the vacuum arc-extinguishing chamber is connected to the static conducting base at the left end, the outer end of the dynamic contact is provided with soft connection and is fixedly connected with the left end of an insulating pull rod, the soft connection is connected with one end of a lower outgoing line rod fixedly sealed at the lower part of the insulating cylinder, and the right end of the insulating pull rod movably extends out of the seal cover. The combined solid encapsulated pole is small in size and relatively convenient and reliable to mount and use, and is suitable for being used as switch equipment.

Description

technical field [0001] The invention relates to a solid-sealed pole, which is a combined solid-sealed pole for switchgear and its working principle. Background technique [0002] Embedded pole means that the conductive parts related to the vacuum interrupter and circuit breaker are embedded in an easily curable solid insulating material such as epoxy resin to form a pole, which is used to control the switchgear. At present, the inflatable ring network cabinets that use SF6 gas as the insulating medium in China, due to environmental protection requirements, SF6 gas is a poisonous gas, has been gradually eliminated, and a new generation of solid insulation, gas insulation, and composite insulation switchgear products are thriving. is in a stage of vigorous development. The three-position switches in these devices also have many structural forms. One type uses a vacuum tube, which is combined with the vacuum interrupter assembly and sealed in the same insulating pole, but the ...
