Abstract
The utility model aims to disclose an electric grounding switch device which comprises a switch body. An electric operating device and a position switch are arranged on the switch body, and the position switch is arranged at an output end of a large shaft of the switch body. Compared with the prior art, the electric grounding switch device has the advantages that the electric operating device is added without changing the switch body, the electric grounding switch device solves the problem that a grounding switch can only be manually opened and closed but cannot be electrically opened or closed, automatic complete equipment is possibly developed, manual operation and electric operation can be arbitrarily switched, the electric grounding switch device has a manual priority function and is simple in structure, safe and reliable to operate and suitable for automatic development trend, the technical requirement of a national grid on bidding is met, and the purposes of the electric grounding switch device are achieved.
Description
Technical field
The utility model relates to a kind of Grunding switch gear device, particularly a kind of electric ground switch device that is used for the high-voltage earthing in power transmission and distribution field.
Background technology
In the prior art, though the fast branch that all has of electric ground switch closes function soon, can possess the ability of closing short circuit current of closing, operation is all accomplished before cabinet with operating grip by manual pick nearby, if operator's violation operation very easily causes casualties.
Along with people's is to the requirement of intelligent electrical network; It is particularly important that automation mechanized operation seems day by day; Particularly as far as earthed switch, the casualties that the remote-control operation earthed switch can avoid misoperation to cause, the realization of earthed switch electric operating function is particularly important as far as automation thus.
In addition, use when earthed switch is used for overhauling more, be generally not charging operation, during maintenance manual operation nearby also essential, electronic and manually between must reliably switch, this just needs reliable arrangement of clutch to accomplish.
Therefore, need a kind of electric ground switch device especially, to solve the above-mentioned existing problem that exists.
The utility model content
The purpose of the utility model is to provide a kind of electric ground switch device, to the defective that prior art exists, overcomes that manual earthed switch can only manually carry out branch, closing operation and can not electronic problem of carrying out branch, closing operation.
To achieve these goals, the technical scheme of the utility model is following:
A kind of electric ground switch device is characterized in that it comprises a Switch main body, and said Switch main body is provided with an electrically operated device and a position switch, and said position switch is arranged on the output of the macro-axis of said Switch main body.
In an embodiment of the utility model; Said electrically operated device comprises a motor, a clutch gear, one first travelling gear, one second travelling gear and valve control electromagnet; Said motor, clutch gear, first travelling gear link to each other mutually with valve control electromagnet successively; Said second travelling gear is arranged on the macro-axis of said Switch main body, and said first travelling gear and said second travelling gear intermesh.
Further, said second travelling gear is fixed on the macro-axis of said Switch main body through axle sleeve.
The electric ground switch device of the utility model, compared with prior art, not doing change at Switch main body increases electrically operated device on the basis; Solved that earthed switch can only manually carry out branch, closing operation and can not electronic problem of carrying out branch, closing operation, for the development of automation complete set of equipments provide maybe, electric and hand can switch arbitrarily; Possesses the manual priority function; Simple in structure, handling safety is reliable, is suitable for the product automation developing direction; Satisfy state's net bid specification requirement, realize the purpose of the utility model.
The characteristics of the utility model can consult this case graphic and below better execution mode detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the structural representation of the utility model electric ground switch device;
Fig. 2 is the structural representation of electrically operated device in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
As depicted in figs. 1 and 2; The electric ground switch device of the utility model; It comprises a Switch main body 100, and said Switch main body 100 is provided with an electrically operated device 110 and a position switch 120, and said position switch 120 is arranged on the output of the macro-axis 130 of said Switch main body 100.
Said electrically operated device 110 comprises a motor 111, a clutch gear 112, one first travelling gear 113, one second travelling gear 114 and valve control electromagnet 115; Said motor 111, clutch gear 112, first travelling gear 113 link to each other mutually with valve control electromagnet 115 successively; Said second travelling gear 114 is arranged on the macro-axis 130 of said Switch main body 100, and said first travelling gear 113 intermeshes with said second travelling gear 114.
Said second travelling gear 114 is fixed on the macro-axis 130 of said Switch main body 100 through axle sleeve.
When needing to close a floodgate; Motor 111 is just changeing; Driving clutch gear 112 rotates; Thereby drive first travelling gear 113, second gear rotate 114 and the macro-axis 130 corresponding energy-stored springs 140 that turn to cross the positions, dead point, position switch 120 automatic switchover motors 111, earthed switch closes a floodgate fast under energy-stored spring 140 effects.
When needing separating brake, motor 111 counter-rotating, corresponding drive clutch gear 112, first travelling gear 113, second gear rotate 114 and macro-axis 130 counter motions, and energy-stored spring 140 is to the dead point, and position switch 120 switches once more, the realization quick acting switching-off.
During manual operation, because valve control electromagnet 115 effects, the clutch gear 112 and first travelling gear 113 are thrown off, and the loop of motor 111 and macro-axis 130 break away from, and can realize manually divide-shut brake fast.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
