Definitions

  • the present disclosure relates to an indicating element suitable for being applied to a pushbutton of an apparatus, in order to provide the pushbutton with any desired information.
  • the indicating element may for example indicate an operative status in which the apparatus is put upon a pushing action on the pushbutton, or may indicate a function or driving operation which is activated on the apparatus by acting on such a pushbutton.
  • the indicating element enables an already existing pushbutton to be adapted to particular standard requirements, i.e. to be easily provided with a desired mark or symbol representing a closing or opening status of an electric circuit, such a status being decided by acting on the corresponding pushbutton.
  • the indicating element of the present disclosure is suitable to be used in connection with a mechanical actuator connected to a circuit breaker of a medium voltage switching apparatus.
  • the term medium voltage refers to applications in the range from 1kV up to some tens of kV, e.g. 30 kV.
  • a circuit breaker of a switchgear can be electrically opened or closed remotely by driving coils or locally by manually exerting a pushing action on an opening pushbutton or on a closing pushbutton.
  • the opening pushbutton and the closing pushbutton are distinguished from one other by respective different symbols and/or colours and/or words.
  • the closing pushbutton may be of a green colour, and may be provided with an "I" mark or also with an "ON" word.
  • the opening pushbutton may be of a red colour, and may be provided with an "O” mark or also with an “OFF” word.
  • the colour, the word, the symbol or mark of each pushbutton may be different according to particular standard requirements and regulations which may vary in the time and/or for different geographical areas or countries. Furthermore, it may be required to change the function or application associated with a given pushbutton and consequently it is necessary to adapt the suitable colour, and/or word, and/or symbol and/or mark to be provided on the pushbutton. All this implies that during the production assembly/storage it is necessary to manage a large number of types of mechanical actuators or similar devices, each having a small difference with respect to the others, due for example to different colours or symbols etc.. Therefore, very high costs are involved in the production, assembly, and storage procedures of these mechanical actuators.
  • the glued stickers are not able to cover a pushbutton in an effective and satisfactory way. Zones of the pushbutton may remain uncovered, especially top and bottom surfaces of the pushbutton, and this may constitute a serious problem when the standard regulations impose to have a particular colour for the visible external surfaces of the pushbutton. Furthermore, the glued stickers, with the passing of time and the use often in harsh working conditions, are prone to separate from the pushbuttons and the graphic quality of the symbols or words which are printed thereon deteriorates.
  • the present disclosure encompasses also an electrical switching apparatus, e.g. a circuit breaker, comprising at least a pushbutton and at least one indicating element of the type described hereinafter and as defined in the appended claims which is associated to such pushbutton.
  • an electrical switching apparatus e.g. a circuit breaker, comprising at least a pushbutton and at least one indicating element of the type described hereinafter and as defined in the appended claims which is associated to such pushbutton.
  • an indicating element 1, 10 which is suitable for being applied to a pushbutton 2, 20 in order to provide the latter with any information needed so as to comply with particular standards or desired requirements.
  • any words or symbols already provided on the pushbutton 2, 20 for indicating, in a given way, an operative status may be covered by the indicating element 1, 10 which is configured for being applied on the pushbutton 2, 20 and which includes information means.
  • the information means may include desired word/s and/or symbol/s and/or mark/s which indicate the above mentioned operative status but in a different desired way with respect to the form of indication given by the state of the art pushbuttons. Only the new desired word/s and/or symbol/s and/or mark/s and/or coloured surfaces of the indicating element 1, 10 result visible to a user once the indicating element 1, 10 has been applied to the pushbutton 2, 20.
  • the indicating element in particular an indicating element 1 and a further indicating element 10 which are suitable for being applied to a pushbutton 2 and a further pushbutton 20 respectively.
  • the pushbutton 2 and the further pushbutton 20, in the example disclosed, comprise an opening pushbutton 2 and a closing pushbutton 20 respectively of a mechanical actuator 3 connected to a circuit breaker of a medium voltage switchgear.
  • the term medium voltage refers to applications in the range from 1 kV up to some tens of kV, e.g. 30 kV.
  • the indicating element 1 and the further indicating element 10 in this case have a shape substantially similar to one other. Due to the minor structural differences between the indicating element 1 and the further indicating element 10, only a more detailed description of the indicating element 1 will follow.
  • the indicating element 1 comprises a cover body 4 which is shaped for covering at least a part of the associated opening pushbutton 2.
  • the cover body 4 comprises a front wall 5, which is intended to be applied to a front surface 6 of the opening pushbutton 2.
  • the front wall 5 is intended to receive a pushing action by a user desiring to act on the pushbutton 2.
  • the cover body 4 further comprises a top wall 7 and a bottom wall 8, which are transversely arranged with respect to the front wall 5 and which are intended to be applied to a top surface 9 and a bottom surface 11 of the opening pushbutton 2 respectively.
  • the cover body 4 further comprises side wall means 13 which extend from the top wall 7 to the bottom wall 8.
  • the side wall means 13, comprises one side wall 13 connecting the top wall 7 to the bottom wall 8.
  • the side wall 13 is in the form of a band wall 13 linking a peripheral zone of the top wall 7 with a further peripheral zone of the bottom wall 8.
  • the side wall 13 may also have different geometrical shapes, for example may be shaped so as to cover the whole side surface of the opening pushbutton 2, and/or can be realized in a different number of parts or pieces; for instance, the indicating element 1 may comprise a pair of side walls provided at opposite lateral side with respect to each other.
  • the function of the opening pushbutton 2, in this exemplifying case, is to put the circuit breaker in an electrical opening status. Accordingly, the information means 12, in this case, acts for indicating the electrical opening function of the opening pushbutton 2.
  • the information means 12 are of the visual type and may comprise visual information marks which are printed or moulded on the cover body 4.
  • the visual information marks can be printed or moulded on the front wall 5.
  • the information means 12 of the indicating element 1 may comprise any desired word/s, and/or mark/s and/or symbol/s and/or coloured surface/s which is/are different from the word/s and/or mark/s and/or symbol/s and/or coloured surface/s already present on the opening pushbutton 2.
  • the indicating element 1 so configured enables to easily and effectively adapt the existing mechanical actuator 3 so as to comply with any standard regulations of a particular geographic area or country and/or to meet specific requirements of a user.
  • a green coloured indicating element 1 can be chosen from the above set of indicating elements 1.
  • the opening button 2 has an inscription such as "push off” and a particular user desires to have a different inscription, such as the word “open” or “OFF” or desires to have only a "O" symbol on the opening pushbutton 2, this can be achieved through an appropriate indicating element 1 which can be chosen from the above set.
  • the indicating element 1 can be obtained from a material having a desired colour.
  • the indicating element 1 can be obtained by moulding a coloured plastics material.
  • the desired coloured aspect of the indicating element 1 so given acts as visual information means included in the indicating element 1.
  • a dye of a specific colour can be applied on the cover body 4, such a dye acting as visual information means included in the indicating element 1.
  • the dye may give the indicator element 1 an external red or green coloured aspect, which is indicative of a the specific operative status in which the circuit breaker can be put by acting on the corresponding pushbutton.
  • the indicating element 1 comprises connecting means 14 configured for connecting the cover body 4 to the opening pushbutton 2.
  • the connecting means comprises snap-fitting means 14 configured for mechanically joining the cover body 4 to the pushbutton 2.
  • the snap-fitting means 14, in the exemplifying version here described, comprises hooking-protrusion-means 14 which protrude from the cover body 4 and are so configured as to removably engage with edge zones of the pushbutton 2.
  • the hooking-protrusion-means comprise a top-hooking-protrusion 15, projecting from a peripheral edge of the top wall 7 and a pair of bottom-hooking-protrusions 16, projecting from a peripheral edge of the bottom wall 8.
  • top-hooking-protrusion 15 and the bottom-hooking-protrusions 16 project from the cover body 4 in a direction away from the front wall 5, so as to be able to engage with rear edge zones of the opening pushbutton 2.
  • the two bottom-hooking-protrusions 16 are mutually parallel and spaced apart from one other.
  • the bottom-hooking-protrusions 16 project from respective opposite end zones of the peripheral edge of the bottom wall 8.
  • the top-hooking-protrusion 15 projects from a middle zone of the top peripheral edge of the top wall 7.
  • the top-hooking-protrusion 15 and the bottom-hooking-protrusion 16 comprise holding tips 21 (see Figures 4 and 9 ) which are configured for clasping the cover body 4 at a top-rear-edge 17 and at a bottom-rear-edge 18 of the opening pushbutton 2.
  • the top-hooking-protrusion 15 and the bottom-hooking-protrusion 16 elastically flex for enabling positioning of the holding tips 21 on a rear surface 22 of the opening pushbutton 2.
  • the further indicating element 10 comprises a left side wall 23 provided on the left side thereof.
  • the further indicating element 10 comprises further information means 24 which have a function analogous to the information means 12.
  • the further information means 24 acts for indicating the electrical closing function of the closing pushbutton 20.
  • the further indicating element 10 like the indicating element 1, enables to adapt the mechanical actuator 3, in particular the closing pushbutton 20, so as to comply with given standard regulations of a particular geographic area or country or so as to meet specific requirements of a user.
  • the further indicating element 10, in the same way as the indicating element 1, covers at least the whole front surface of the closing pushbutton 20, thus replacing the already existing inscription/s and/or mark/s and/or symbol/s and or coloured surface/s of the closing pushbutton 20 with new ones, according to the desired requirements.
  • a black coloured indicating element 1 can be chosen from the above set of indicating elements 10.
  • the closing pushbutton 20 has an inscription such as "push on” and a particular user desires to have a different inscription, such as the word “close” or “ON” or desires to have only a "I” symbol on the closing pushbutton 20, this can be achieved through an appropriate indicating element 10 which can be chosen from the above set.
  • the indicating element 1, 10 of the present disclosure there is no longer need for managing a large number of types of mechanical actuators or similar devices, each having a small difference with respect to the others, due for example to different colours or symbols required for the pushbuttons.
  • the indicating element of the present disclosure it is also possible to assemble a mechanical actuator with one or more pushbuttons which have a neutral colour and/or which are devoid of any words, marks and symbols, thus noticeably reducing the overall production costs thereof.
