Abstract
The utility model discloses a terminal post of a vacuum circuit breaker. The terminal post comprises a ceramic bottle, a conducting clamp, a conducting bar, a vacuum arc-extinguishing chamber disposed in the ceramic bottle, an outgoing terminal disposed on the vacuum arc-extinguishing chamber, and a moving contact device and a fixed contact device disposed in the vacuum interrupter, and is characterized by further comprising an oil buffer and a current transformer disposed in the ceramic bottle, wherein the current transformer is connected to the conducting clamp by the conducting bar. The terminal post of the vacuum circuit breaker has the advantages of multiple functions, good effects and the like.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, specifically, relates to a kind of vacuum circuit breaker polar.
Technical field
The technical problem that the utility model will solve is that to vacuum circuit breaker polar function singleness in the prior art, the defective of poor effect provides a kind of function many, effective vacuum circuit breaker polar.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of vacuum circuit breaker polar; Comprise porcelain vase, conductive clip, busbar; Be located at the interior vacuum interrupter of said porcelain vase, be located at the outlet terminal of said vacuum interrupter and be arranged at indoor moving contact of vacuum extinction and static contact head device; It is characterized in that: also comprise oil bumper and the current transformer be located in the said porcelain vase, said current transformer links to each other through busbar with conductive clip.
Further, also comprise touch spring and spring base, said touch spring is placed on the said spring base.
Concrete, said spring base one end is connected through double-screw bolt with said vacuum interrupter.
Further, the said spring base other end is connected with guide rod.
Advantages such as compared with prior art, it is many that a kind of vacuum circuit breaker polar that the utility model provides possesses function, effective.
Background technology
Vacuum circuit-breaker is the visual plant in the power network, and it uses vacuum extinction technology, has that breaking capacity is strong, contact is difficult for oxidation, electric arc does not expose, and is safe and reliable, the advantage of high life, and make it in power distribution network, obtain widespread.Vacuum circuit-breaker comprises vacuum interrupter, and vacuum tube is housed in the arc control device.And, when carrying out separating brake and closing a floodgate, be easy to generate high-voltage arc between the dynamic and static contact because dynamic/static contact is operated in the high-tension circuit; Its infringement to contact is very serious; For avoiding this infringement, dynamic/static contact is installed in the vacuum chamber, so that the arc extinction performance of vacuum circuit-breaker is better.But bring a problem simultaneously, vacuum circuit-breaker is often to the having relatively high expectations of vacuum degree in vacuum chamber, in case vacuum degree reduces then lost original arc extinguishing effect.Before this, the insulation crust of general vacuum interrupter is exposed in the air, exists by extraneous dust, moist pollution problems.For reducing this influence, require the shell of vacuum interrupter that enough length is arranged, this not only influences the miniaturization of vacuum interrupter; Also influence the Performance And Reliability of vacuum interrupter; After replace with pole gradually, but existing vacuum circuit breaker polar function singleness, poor effect.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is a kind of vacuum circuit breaker polar structural representation of the utility model;
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, below in conjunction with embodiment and accompanying drawing, to further explain of the present invention:
See also Fig. 1; A kind of vacuum circuit breaker polar; Comprise porcelain vase 100, conductive clip 200, busbar 300; Be located at vacuum interrupter 400 in the said porcelain vase 100, be located at the outlet terminal 410 of said vacuum interrupter 400 and be arranged at trigger device (not illustrating) and the static contact head device (not illustrating in the accompanying drawing) in the vacuum interrupter 400; Also comprise oil bumper 500 and the current transformer 600 be located in the said porcelain vase 100, said current transformer 600 links to each other through busbar 300 with conductive clip 200.
Further, also comprise touch spring 700 and spring base 710, said touch spring 700 is placed on the said spring base 710.
Concrete, said spring base 710 1 ends and said vacuum interrupter 400 are connected through double-screw bolt.
Further, said spring base 710 other ends are connected with guide rod 800.
Advantages such as compared with prior art, it is many that a kind of vacuum circuit breaker polar that the utility model provides possesses function, effective.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
