, Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of circuit breakers, and more specifically relates to, a tulip contacts suitable for a switching device, in particular to a circuit breaker.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Electrical switching apparatus, such as circuit breakers, provide protection for electrical systems from electrical fault conditions such as, for example, current overloads, short circuits, abnormal voltage and other fault conditions. Typically, circuit breakers include an operating mechanism which opens electrical contact assemblies to interrupt the flow of current trough the conductors of an electrical system in response to such fault conditions. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.
[0004] Circuit breakers are generally installed to protect equipment from overcurrent (than its rated current) situations, for example, when a short circuit or ground fault occurs in an electrical supply conductor. Upon the occurrence of any such overcurrent condition, electrical contacts inside circuit breaker get opened, and stop supply of electrical current to equipment. Designs for circuit breakers generally include accommodations for both high quiescent currents and high withstand currents. To maintain a high withstand current rating, the contacts must be locked closed at the current withstand rating and be able to withstand the large electrodynamics repulsion forces generated by the current flow.
[0005] Tulip contact is generally used in middle and/or high voltage switching devices. The contact fingers are essentially intended for rated electrical current disconnection operation and current transmission by providing a contact finger-trap which is connected to a mating contact. In the medium voltage field, it is known the use of a tulip-contact-assembly for the electrical connection of a movable conducting terminal, provided on a draw-out circuit breaker, to a stationary conducting terminal of switchgear.
[0006] A known tulip-contact-assembly comprises a support-frame which is defined by a pair of star-shaped flanges which are mutually parallel and spaced apart and which are fixed to one other by rod elements. The tulip-contact-assembly comprises a plurality of distinct and separated contact-fingers which rest into seat-portions obtained on the star-shaped flanges and are urged against the latter by helicoidal springs extending with a ring-shape around a central axis of the support-frame. Suitable external recesses are obtained on the contact-fingers in order to house, and keep in a correct position, the helicoidal springs. In a further type of tulip-contact-assembly the support-frame comprises, instead of the pair of star-shaped flanges, a solid support-core-element with which the contact-fingers are coupled through more helicoidal springs and apposite anchoring elements. Therefore, such a tulip-contact-assembly comprises a rather high number of distinct interconnected components, each of which is subjected to dedicated manufacturing-processes.
[0007] Each contact-finger extends parallel to the above mentioned central axis and comprises a front contact-portion for removably engaging with a stationary contact-pin of switchgear, and a rear-contact-portion intended to keep in contact with a conducting-arm of the movable circuit breaker.
[0008] The front contact-portion and the rear-contact portion have rectangular cross-sections and plane-contact-surfaces and tangentially contact with the curved surface of the stationary contact-pin and of the conducting-arm respectively. This means that the front contact-portion and the rear-contact-portion touch the stationary contact-pin and the conducting-arm respectively in single localized contact zones. In order to improve the electrical transmission capability, a further type of tulip-contact-assembly has been proposed in the past which comprises a greater number of contact-fingers, compared with the above discussed type of tulip-contact-assembly, and which increases the number of electrical contact-zones with the stationary contact-pin and with the conducting-arm. In this type, the contact-fingers are distributed around the central axis in pairs and each contact-finger has a smaller thickness with respect to the previously discussed contact-fingers. Nevertheless such a tulip-contact-assembly is even more structurally complicated with respect to the previously discussed tulip-contact-assembly, due to the high number of distinct interconnected components. Furthermore, the high number of contact-fingers implies larger surfaces to be treated for complying with conductivity-requirements, and this means a cost increase in the manufacturing which makes this tulip-contact-assembly rather expensive.
[0009] All the versions of tulip-contact-assembly above discussed therefore include a remarkable plurality of distinct parts that are mutually mechanically interconnected thus defining a multitude of junction zones that prove to be rather critical as far as the heat-dissipation, electrical-transmission-capability and mechanical resistance requirements are concerned. Further, in the existing tulip assembly, contacts without spacer can collapse due to the tolerance on the contact finger and spring force which leads to the high insertion force and damage the silver plating but with the spacer in place contact. Furthermore, in the conventional tulip contact assembly, there is a difficulty in inserting breaker. Additionally, in the existing prior-art, there is high insertion force.
[00010] Whereas there is certainly nothing wrong with existing tulip-contact-assembly, nonetheless, there still exists a need to provide an efficient, effective, reliable, and improved tulip contact assembly that improves the electrical connections, in particular by providing a technical solution which makes possible to obtain a reliable connection with increased conductivity performances, at the same time, is structurally simple and cheap to obtain. Further, there is also need of an improved tulip contact assembly that improves the reliability of the plug-in contact. Furthermore, there is a dire need of an improved tulip contact assembly that significantly reduces the insertion force.

[00066] In an embodiment, an MCCB (6) can be connected to a panel board, the operator has to mount the MCCB (6) and connect all the terminations on the breaker to a busbar using cables. During the time of maintenance the operator must switch OFF the upstream breaker (which will lead to the closure of various other dependency), then remove all the terminations and un-mount the breaker from the panel in order to do his maintenance work. Using a Plug-in circuit breaker decreases the time taken in doing this operation. Initially the operator has to mount the Plug-in base (7) to the panel board and connect all the terminations to the base. Now he will attach the conversion kit to the breaker and insert it into the base. At the time of maintenance the operator just has to switch OFF the MCCB (6) and remove the breaker from the base and it can substitute the main breaker with a temporary breaker. After maintenance activities are over on the main breaker he can replace the temporary breaker. By doing this the lead time during maintenance can be avoided. The working of plug-in is explained as follows, one of the important functions of plug-in unit is to establish electrical contact between the busbar and breaker, for this there are fixed contacts placed in the plug-in base (7). The moving pin (5) can be attached to the breaker by means of bolts is forced into the contact when the user pushes the breaker assembly into the plug-in base (7).
