Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: an operating handle of an isolating switch comprises a handle head 1 and a crank handle 3, wherein the handle head 1 is connected with the crank handle 3 in a matching way;

or isolator operating handle includes handle head 1, extension head 2 and crank 3, and handle head 1, extension head 2 and crank 3 cooperate in proper order to connect, realize the effect that can dismantle at any time between each part to make things convenient for the classification of part to deposit and maintain.

The isolating switch operation groove 4 has been seted up to handle 1, and the quantity of handle 1 is a plurality of, sets up the isolating switch operation groove 4 that the structure differs on every handle 1, and the concrete shape of isolating switch operation groove 4 can be chooseed for use according to all kinds of switches in the transformer substation.

The handle head 1 is provided with a sleeve opening part 5, a main part 6 and a handle head insertion part 7 which are connected in sequence, and the isolating switch operation groove 4 is arranged at the sleeve opening part 5; the extension head 2 is provided with an extension head main body 8 and an extension head insertion part 9 which are connected with each other, the length of the extension head main body 8 is 100mm or 150mm, the distance between a hand and the handle head 1 is prolonged, and the possibility of accidental electric shock is reduced. The extension head main body 8 is provided with an extension head slot 12; the crank 3 is provided with a crank mounting head 10 and an adjustable handle which are connected with each other, the handle plug insertion part 7 is matched with the extension head slot 12 and the mounting head slot 13, and the mounting head slot 13 is matched with the extension head insertion part 9. The handle plug-in part 7 and the extension plug-in part 9 are designed in a square shape, when the handle plug-in part 7 is plugged into the extension plug-in part 12 and the extension plug-in part 9 is completely plugged into the mounting head slot 13, or the handle plug-in part 7 is directly plugged into the mounting head slot 13, the crank 3 can be rotated to perform the rotation operation of the handle 1 on various disconnecting switches.

In order to avoid the accidental separation among the handle head 1, the extension head 2 and the crank 3, positioning protrusions are arranged outside the handle head insertion part 7 and the extension head insertion part 9, and positioning grooves matched with the positioning protrusions are arranged in the extension head slot 12 and the mounting head slot 13. The fixing among the handle head 1, the extension head 2 and the crank handle 3 is realized through the matching of the positioning groove and the positioning protrusion.

Because the environment of the isolating switch is complex, the rotating radius of the adjustable handle can be adjusted according to specific construction conditions, and the extending length of the inserting rod 15 can be fixed through rotating a screw by arranging the pipe sleeve 14 and the inserting rod 15 and inserting the inserting rod 15 into the pipe sleeve 14; the grab handle 11 is arranged outside the inserting rod 15, and the grab handle 11 is a rotatable ABS (acrylonitrile butadiene styrene) handle, so that an operator can hold the grab handle 11 to rotate, and the possibility of electric shock is reduced.

Referring to fig. 6, the present invention further provides a portable case:

handle 1, extension head 2 and crank 3's mounting groove has been seted up to the suitcase, and the quantity of the specific handle 1's of quantity cooperation of handle 1 quantity sets up to guarantee that every handle 1 can both obtain stable and reliable saving. The mounting groove of extension head 2 is equipped with two, and specific length cooperation extension head 2 sets up. Therefore, each device in the equipment can be reasonably placed, maintenance is convenient, and management is facilitated.

The working principle is as follows: because the required operation groove structure of all kinds of switches in the transformer substation is different, if every kind of switch all is equipped with an operating handle, then it deposits and the transport will occupy operating personnel very big time and space, and this application is through the cooperation mode that sets up "a handle main part + multiple handle head", good this problem of having solved.

When in use, the handle head 1 with the proper isolating switch operation slot 4 is selected according to the requirement, and if the operation process has no electric shock hazard, the handle head insertion part 7 can be directly inserted into the installation head slot 13; if the whole operation process has the possibility of electric shock, the extension head 2 can be selected according to the situation, the handle head insertion part 7 is inserted into the extension head slot 12, and the insertion part 9 is inserted into the mounting head slot 13, so that the problem of accidental electric shock can be avoided in the process of rotating the crank 3.

The length of the part of the pipe sleeve 14 is 150mm, the length of the inserted rod 15 is 200mm, the radius of the handle can be randomly adjusted according to the surrounding environment and the requirement of a site, the radius range is 150mm and 300mm, and the range is suitable for all disconnecting switches and various disconnecting switches in the AIS transformer substation. In the process of operating the crank 3, a user can adjust the position of the inserted rod 15 inserted into the pipe sleeve 14 according to the needs of the user and fix the inserted rod through a rotating screw, so that the integral rotating radius of the crank 3 can be adjusted, and the crank is further matched with an operator to complete work.

Corresponding numbers are arranged between the mounting groove in the portable box and the parts of each operating handle, so that the parts can be conveniently stored and selected. The portable box is convenient for operators to carry, reduces the storage occupied area of operating tools, is not easy to lose, and simplifies the maintenance and management.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
