Definitions

  • the invention relates to a switchgear, and more particularly to the bus bar arrangement of the switchgear.
  • switchgear consists of bus bar for conducting electricity. These bus bars are located on the top of the switchgear, above which the gas duct for extinguishing internal arc is provided. This arrangement renders the access to the bus bars from top difficult thereby requiring access to the bus bar from the front or from the rear of the switchgear. Besides this, having a vent on the top of the switchgear reduces the ingress protection and as such requires caution. Such arrangement of the bus bar and the gas duct increases the size of the switchgear resulting in a larger switchgear occupying more space.
  • the contact arms of the circuit breaker are positioned parallel so as to work in conjunction with the bus bar further contributes to usage of more space.
  • the parallel contact arm arrangement of the circuit breaker creates more dynamic repulsive forces during short circuit and increases the chance for failure of the switchgear.
  • switchgear that has a bus bar arrangement that can be correspondingly positioned along with contact arms of the circuit breaker and the gas duct, that makes the switchgear more compact and reliable in operation.
  • the present invention provides a switchgear comprising a circuit breaker and a bus bar.
  • the switchgear of the invention comprises a circuit breaker and a bus bar arrangement.
  • the circuit breaker have one set of contacts disposed either in upward or downward direction at an angular relationship with other set of contacts.
  • the bus bar arrangement is positioned in corresponding relationship with the one set of contacts and the other set of contacts of the said circuit breaker.
  • FIG. 1 shows a switchgear in accordance with the prior art
  • Fig. 2a shows a switchgear with the bus bar arrangement located in the top portion of the switchgear in accordance with one embodiment of the invention
  • Fig. 2b shows a switchgear with the bus bar arrangement located in the bottom portion of the switchgear in accordance with another embodiment of the invention
  • Fig. 3a shows the bus bar arrangement of the switchgear of Fig. 2a depicting the bushing
  • Fig. 3b shows the bus bar arrangement of the switchgear of Fig. 2 b depicting the bushing.
  • Fig. 1 shows a switchgear (100) according to the prior art.
  • the switchgear (100) comprises a circuit breaker (110) having two contact sets (111, 112) parallel to each other.
  • the bus bar arrangement (120) is located in the top portion of the switchgear (100) and is electrically connectible to the contact sets (111, 112) of the circuit breaker (110) through suitable bushings.
  • An arc duct (130) is provided over the bus bar arrangement ( 120), and may be filled with air or gas suitably to reduce internal arcs.
  • This arrangement of the switchgear (100) with circuit breaker (110) having two contact sets (111, 112) that are parallel, and having a bus bar arrangement (120) and arc duct (130) located on top portion renders the switchgear larger in size occupying more space. Also.
  • the two contact sets (111, 112) being parallel to each other creates more dynamic repulsive forces during short circuit thereby increasing the chances of failure and reducing the reliability in operation of the switchgear (100).
  • the invention is aimed at providing such a switchgear. Accordingly, the invention is further described with reference to non-exhaustive exemplary embodiments depicted in Figs. 2a, 2b, 3a, and 3b. These embodiments shown in Figs. 2a, 2b, 3a, and 3b do not limit the scope of the invention.
  • a switchgear (200) according to one embodiment of the invention is shown, in which the switchgear (200) comprises a circuit breaker (210) having two sets of contacts (211a, 212).
  • the one set of contacts (211a) is provided at an angular relationship with the other set of contacts (212).
  • the angular relationship being perpendicular and the one set of contacts (211a) being positioned in upward direction.
  • the one set of contacts (211a) has slidable contacts and the other set of conatcst (212) has tulip contacts.
  • the bus bars (220) may have a circular cross section to provide improved or increased dielectric performance.
  • the bus bar arrangement (300a) is located on the top portion of the switchgear (200) and is suitably located along with an arc duct (230) integrated therein. Such suitably locating the arc duct (230) may mean locating the arc duct (230) at one side of the bus bar arrangement (300a).
  • the movement of the circuit breaker (210) in and out correspondingly opens and closes the shutters of the shutter mechanism linked or connected thereto with the circuit breaker (210), allowing the one set of contacts (211a) and the other set of contacts (212) to engage or disengage respectively, with their respective contacts of the bus bar (220) thereby breaking or making the electrical circuit.
  • the bushing (310a) has an opening at the top to accommodate the contacts of the bus bar (220), while the opening at the bottom and front portion of the bushing (310a) accommodates the one set of contacts (211a) i.e,, the sildable contacts of the circuit breaker (210).
  • the ingress protection of the switchgear (200) is improved as there are no vents on the top portion of the switchgear (200).
  • the bus bars (220) are now easily accessible say from the top of the switchgear (200) unlike the prior art switchgear (100) where there is an arc duct (130) that makes the access to the bus bar (220) more difficult.
  • Figs. 2b and 3b shows a switchgear (200) according to another embodiment of the invention, in which the switchgear (200) is almost similar in type in comparison with the switchgear shown in Figs. 2a and 3a.
  • This embodiment of the switchgear (200) shown in Figs. 2b and 3b comprises a bus bar arrangement (300b) having bus bar (220) and located on the bottom portion of the switchgear (200).
  • the one set of contacts (211b) is in angular relationship with the other set of contacts (212), such angular relationship may be perpendicular with the one set of contacts (211b) being in downward direction.
  • the movement of the circuit breaker (210) in and out correspondingly opens and closes the shutters of the shutter mechanism linked or connected thereto with the circuit breaker (210), allowing the one set of contacts (21 lb) and the other set of contacts (212) to engage or disengage respectively, with their respective contacts of the bus bar (220) thereby breaking or making the electrical circuit.
  • the bushing (310b) has an opening at the bottom to accommodate the contacts of the bus bar (220), while the opening at the top and front portion of the bushing (310b) accommodates the one set of contacts (211b) i.e,, the sildable contacts of the circuit breaker (210) during the corresponding inward movement of the circuit breaker (210).
  • the bus bar (220) can be accessed from the front portion of the switchgear (200).
