Utility model content
In sum, for solving existing technical problem, the utility model provides a kind of dolly being exclusively used in the busbar grounding of PT cabinet.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of dolly being exclusively used in the busbar grounding of PT cabinet, comprise supporting bracket and fixed head, the bottom of described supporting bracket is provided with directive wheel, described fixed head is vertically arranged in described supporting bracket, in the side, top of described fixed head, described high voltage induction device is installed, described high voltage induction device is circumscribed with connection copper bar away from one end of described fixed head, and described connection copper bar is circumscribed with away from one end of described high voltage induction device the compression joint type moving contact matched with PT cabinet bus contact;
The grounding switch moving contact of joystick and ground connection is provided with at the middle part of described fixed head, the position corresponding with described grounding switch moving contact in the below of described connection copper bar is provided with grounding switch fixed contact, described connection copper bar connects described grounding switch fixed contact by connector, described joystick can drive described grounding switch moving contact to move by connecting rod, makes the closed of itself and described grounding switch fixed contact or disconnects;
Be provided with charged display device in the described bottom stating fixed head, described charged display device is connected with described high voltage induction device by wire.
Further, the porcelain insulator for supporting described connector is provided with in the position of the corresponding described connector of described fixed head.
Further, described high voltage induction device, described connection copper bar and described compression joint type moving contact are in the inside of insulating sleeve.
The beneficial effects of the utility model are: a kind of dolly being exclusively used in the busbar grounding of PT cabinet that the utility model provides, replace traditional artificial busbar grounding, while guarantee operator safety, accelerate the speed of busbar grounding work greatly, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ground connection.
1, supporting bracket, 2, fixed head, 3, high voltage induction device, 4, directive wheel, 5, connect copper bar, 6, bus contact, 7, compression joint type moving contact, 8, joystick, 9, grounding switch moving contact, 10, grounding switch fixed contact, 11, connector, 12, charged display device, 13, porcelain insulator, 14, insulating sleeve.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of dolly being exclusively used in the busbar grounding of PT cabinet, comprises supporting bracket 1 and fixed head 2, and the bottom of described supporting bracket 1 is provided with directive wheel 4, is realized the transfer of dolly by directive wheel 4.Described fixed head 2 is vertically arranged in described supporting bracket 1, in the side, top of described fixed head 2, described high voltage induction device 3 is installed, described high voltage induction device 3 is circumscribed with connection copper bar 5 away from one end of described fixed head 2, and described connection copper bar 5 is circumscribed with away from one end of described high voltage induction device 3 the compression joint type moving contact 7 matched with PT cabinet bus contact 6.Described high voltage induction device 3, described connection copper bar 5 and described compression joint type moving contact 7 are in the inside of insulating sleeve 14, are got up by above-mentioned part covers by insulating sleeve 14, avoid it to be exposed to outside.
The grounding switch moving contact 9 of joystick 8 and ground connection is provided with at the middle part of described fixed head 2, the position corresponding with described grounding switch moving contact 9 in the below of described connection copper bar 5 is provided with grounding switch fixed contact 10, described connection copper bar 5 connects described grounding switch fixed contact 10 by connector 11, is provided with the porcelain insulator 13 for supporting described connector 11 in the position of the corresponding described connector 11 of described fixed head 2.Described joystick 8 can drive described grounding switch moving contact 9 to move by connecting rod, makes the closed of itself and described grounding switch fixed contact 10 or disconnects.
Be provided with charged display device 12 in the described bottom stating fixed head 2, described charged display device 12 is connected with described high voltage induction device 3 by wire.
When needing to work to the busbar grounding of PT cabinet, first promote Plantago minuta and exercise the compression joint type moving contact 7 arrival position corresponding with bus contact 6, continue to promote the dolly compression joint type moving contact 7 that moves ahead and can prop up bus contact 6, compression joint type moving contact 7 is contacted well with bus contact 6.Then observing charged display device 12, because compression joint type moving contact 7 connects charged display device 12 by high voltage induction device 3, just can judge that whether PT cabinet bus is charged by observing charged display device 12.If judge that bus is not charged, just drive grounding switch moving contact 9 action realization and grounding switch fixed contact 10 to close by joystick 8, complete busbar grounding; If judge that bus is charged, then can not carry out described landing operation, need again to examine and fulfil power failure operation and reaffirm that bus just can carry out ground connection work without after electricity.
In sum, a kind of dolly being exclusively used in the busbar grounding of PT cabinet that the utility model provides, replaces traditional artificial busbar grounding, while guarantee operator safety, accelerates the speed of busbar grounding work greatly, improves operating efficiency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
