Description
Technical Field
The utility model belongs to electric power construction tool field relates to an insulating pull rod, especially a 10KV insulating pull rod suitable for jet fuse.
Background
With the continuous development of the engineering of changing coal into electricity, a large number of new devices are put into production in succession, and a batch of column-mounted comprehensive transformers with novel structures fall off, namely, the jet fuse. The fuse is mainly used for urban and rural power transmission and distribution systems in the power industry, can realize full-range protection (overload and open circuit faults), and is an updated product of the traditional drop-out high-voltage fuse. The jet fuse is composed of a porcelain bushing and a fuse tube inserted in the porcelain bushing, the lower contact of the porcelain bushing is of a horn mouth structure, the lower contact has the functions of righting and guiding the fuse tube, the combined pressing success rate reaches 100%, and the defect that the traditional drop fuse is low in switching-on success rate is overcome.
Because the fuse wire of fuse is the tubulose, need during the installation to have a power failure with this circuit, climb the pole by the operating personnel and upwards insert the installation with the fuse tube from fuse porcelain bushing bottom, so both prolonged user's power off time, also influenced the reliability of power supply.
Through a search for a patent publication, no patent publication that is the same as the present patent application is found.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, provide a simple structure, easy to assemble, but live working, guarantee the reliability of power supply, provide installation effectiveness, the 10KV insulating pull rod suitable for jet fuse who easily realizes.
The utility model provides a its technical problem take following technical scheme to realize:
a10 KV insulated pull rod suitable for a jet fuse, which comprises an insulating rod, and is characterized in that: the top of the insulating rod is provided with an external thread, the insulating rod further comprises a clamping seat, the clamping seat is of a structure that an internal thread is arranged on the inner wall of one end of the clamping seat, an arc clamping plate is arranged on the inner wall of the other end of the clamping seat at intervals, and the clamping seat and the insulating rod are installed in a threaded mode.
And the clamping seat is sleeved with the outer sheath.
Moreover, the outer sheath is made of ABS engineering plastics.
The utility model has the advantages that:
1. the 10KV insulated pull rod suitable for the jet fuse can realize the operation of installing the fuse tube in a live-line manner, shorten the power failure time of a user and improve the power supply reliability.
2. The 10KV insulating pull rod suitable for the jet fuse can prevent the damage to the porcelain sleeve part of the fuse during operation through the arrangement of the outer sheath.
3. The utility model has the advantages of scientific and reasonable design, but have easy to assemble, live working, guarantee the reliability of power supply, provide installation effectiveness, easily realize, be one kind have higher novelty be applicable to the 10KV insulating pull rod of injection formula fuse.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings:
a10 KV insulated pull rod suitable for a jet fuse comprises an insulating rod 2, and is characterized in that: the top of the insulating rod is provided with an external thread, and the insulating rod clamping device further comprises a clamping seat 3, wherein the clamping seat is of a structure that an internal thread is arranged on the inner wall of one end of the clamping seat, an arc clamping plate 4 is arranged on the inner wall of the other end of the clamping seat at intervals, and the clamping seat and the insulating rod are installed in a threaded mode.
The height from the upper part of the internal thread in the clamping seat to the bottom of the clamping arc plate is the same as the height from the bottom of the fuse tube to the upper end face of the bulge of the fuse tube.
The clamping seat is characterized by further comprising an outer sheath 1, and the outer sheath is sleeved outside the clamping seat.
The outer sheath is made of ABS engineering plastics.
The utility model discloses when using, need install fuse tube 6 earlier in insulating pull rod clamp the seat, after the installation is stable, stand insulating pull rod again, the manual work is in the porcelain bushing 7 is inserted with the fuse tube at subaerial handheld insulator spindle.
When the fuse tube is installed, the installation is completed by means of two lugs 5 which are oppositely arranged at two ends of a copper sleeve on the fuse tube, namely, the two lugs are arranged between two clamped arc plates on a clamping seat, the bottom of the fuse tube is contacted with the top of an insulating rod, then the fuse rod is screwed, the two lugs are screwed to the lower parts of the clamped arc plates, and the fuse tube is stably installed on an insulating pull rod by means of up-down positioning; after the insulating pull rod is inserted into the porcelain sleeve, the two convex blocks are screwed out from the lower part of the clamping arc plate, and then the insulating pull rod can be separated.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
