Abstract
The utility model relates to an indoor high-voltage vacuum breaker, which comprises a primary conduction part, a box body, a manipulation mechanism and a chassis vehicle. The primary conduction part consists of a vacuum arc extinguishing chamber, vacuum poles, a fixed contact and a movable contact; the fixed contact and the movable contact are arranged inside the vacuum arc extinguishing chamber; the movable contact is connected with the lower vacuum pole and connected with the manipulation mechanism through a pull rod; and the fixed contact is connected with the upper vacuum pole. Primarily, the primary conduction part is poured and fixedly sealed by epoxy resin; and the inner surface of an epoxy resin sealing cylinder on the outer side of the pull rod has a corrugated tube structure to ensure that the inner creepage distance between the lower vacuum pole and the manipulation mechanism reaches 240 mm. The indoor high-voltage vacuum breaker has the advantages of high vacuum degree, good insulation performance, long service life of products and the like, and is suitable for a high-voltage power system of 24kV voltage level.
Description
Technical field
The utility model relates to a kind of switchgear, particularly about a kind of vacuum circuit-breaker.
Background technology
Indoor high-voltage vacuum circuit breaker is used for the control and the protection equipment of power plant, transformer station, industrial and mining enterprises' electric equipment.Its structure is made up of pole part, casing and operating mechanism, chassis car three parts, the pole part is made up of vacuum interrupter, vacuum pole, fixed contact, moving contact, fixed contact, moving contact are indoor in vacuum extinction, moving contact is connected with following vacuum pole, and connect with operating mechanism by pull bar, fixed contact is connected with last vacuum pole.One of its shortcoming be vacuum interrupter and upper and lower vacuum pole by the encapsulation of epoxy resin sleeve, vacuum degree is low, influences product useful life; Two of its shortcoming is the distance between moving contact and casing and the operating mechanism short (for 240mm), and the class of insulation is low, can only be suitable for the electric power system of 12KV electric pressure, and can not be suitable for the high-voltage electric power system of 24KV electric pressure.
Summary of the invention
One of the purpose of this utility model is the shortcoming that exists at prior art, provides a kind of vacuum degree height, the indoor high-voltage vacuum circuit breaker of long product lifecycle;
Two of the purpose of this utility model is the shortcomings that exist at prior art, and a kind of class of insulation height is provided, and can be suitable for the indoor high-voltage vacuum circuit breaker of 24KV electric pressure.
The technical solution of the utility model comprises primary conductive part, casing and operating mechanism, chassis car, the primary conductive part is made up of vacuum interrupter, vacuum pole, fixed contact, moving contact, fixed contact, moving contact are indoor in vacuum extinction, moving contact is connected with following vacuum pole, and be connected with operating mechanism by pull bar, fixed contact is connected with last vacuum pole.Mainly be that the primary conductive part is sealed admittedly by poured with epoxy resin; The epoxy sealing tube inner surface in the pull bar outside is a bellows structure, makes down vacuum pole to the interior creepage distance between the operating mechanism reach 240mm.
One of advantage of the present utility model is that primary conductive part is sealed admittedly by poured with epoxy resin, guarantees the vacuum degree of vacuum interrupter, improves insulation property and product useful life;
Two of advantage of the present utility model is that the epoxy sealing tube inner surface in the pull bar outside is a bellows structure, increase the primary conductive part to the shortest creepage distance between the operating mechanism, make down vacuum pole to the interior creepage distance between the operating mechanism reach 240mm, be suitable for the high-voltage electric power system of 24KV electric pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Indoor high-voltage vacuum circuit breaker as shown in Figure 1, comprise primary conductive part, casing 1 and operating mechanism 3, chassis car 2, the primary conductive part is made up of vacuum interrupter 7, vacuum pole, fixed contact 9, moving contact 8, fixed contact 9, moving contact 8 are in vacuum interrupter 7, moving contact 8 is connected with following vacuum pole 6, and be connected with operating mechanism 3 by pull bar 4, fixed contact 9 is connected with last vacuum pole 10.The primary conductive part is sealed admittedly by poured with epoxy resin, guarantees that vacuum interrupter 7 has higher vacuum degree, improves the working life of vacuum interrupter 7, the reinforced insulation performance.The inner surface of the epoxy sealing tube 5 in pull bar 4 outsides is a bellows structure, increase the primary conductive part to the shortest creepage distance between the operating mechanism 3, make down vacuum pole 6 to the interior creepage distance between the operating mechanism 3 reach 240mm, improve the class of insulation of product, be suitable for the high-voltage electric power system of 24KV electric pressure.
