Description

Multifunctional insulating rod

Technical Field

The utility model belongs to the technical field of the equipment of installation, maintenance, repair or dismantlement cable or electric wire is exclusively used in, especially, relate to a multi-functional insulator spindle.

Background

The insulating rod is a uniform name of an insulating tool composition specially used in an electric power system, and can be used for live working, live overhaul and live maintenance working appliances. The existing insulating rod is used for an insulating tool for operating live equipment for a short time, such as a high-voltage isolating switch, a drop fuse and the like. However, when the device is used for tests such as alternating current withstand voltage test and partial discharge test of a transformer, the test efficiency is low, the test cost is high, and the like, for example, when the alternating current withstand voltage test and the partial discharge test of the transformer are carried out, a field operator needs to fix the pressurizing wire by using the insulating rod, but the insulating rod does not have any fixable device, so that a large amount of insulating glue is consumed to fix the insulating rod and the pressurizing wire. In addition, in a partial discharge test of the transformer, a site constructor needs to use an insulating rod with a certain length and connect a test wire outside the insulating rod to achieve the purpose of a square wave test, but the test wire is too long and fixed, so that poor contact with the head end of the insulating rod is caused, and the test result and the working efficiency are influenced. Therefore, further improvement is needed to solve the problems of large consumption of the insulating tapes and low test efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model provides a multifunctional insulating rod, aim at make the insulator spindle can fix on cylinder or other positions to can fix pressure line and test wire.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a multifunctional insulating rod, includes the main pole body of being made by the epoxy glass stringing, and the main pole body divides into a plurality of branch body of rod, connects through the metal buckle between each branch body of rod, and the external surface welding of main pole body is a plurality of external buckles of adjustable size, and a plurality of built-in buckles of internal welding of main pole inlay a surface test line of being made by insulating material on the built-in buckle, and the one end of test line is connected with the top of the main pole body, and the afterbody of the main pole body is stretched out to the other end of test line.

Further, the main rod body is made of plastic tape or bakelite.

In order to achieve the above object, the utility model discloses following beneficial effect has:

the utility model discloses an at the external buckle of a plurality of adjustable sizes of the surface welding of the mobile jib body, a plurality of built-in buckles of the internal welding of mobile jib inlay a surface and by the test line that insulating material made on built-in buckle, the one end of test line is connected with the top of the mobile jib body, the afterbody of the mobile jib body is stretched out to the other end of test line. The problem that a large amount of insulating tapes need to be consumed for fixing the pressurizing line and the insulating rod on site is solved by fixing the pressurizing line and the insulating rod at the cylinder or other positions through external buckles, and the test cost is reduced. Simultaneously, fix through the built-in buckle in the insulator spindle in the poor contact problem of square wave process test wire and insulator spindle prelude is beaten in the face of the transformer partial discharge test, prevent to lead to the poor contact problem with the insulator spindle head end because of the test wire overlength is fixed, improve test efficiency and reduce test time.

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.

As shown in fig. 1 and 2, the multifunctional insulating rod comprises a main rod body 1 made of epoxy glass cloth tubes, wherein the main rod body 1 is divided into a plurality of branch rod bodies, the branch rod bodies are connected through metal buckles, a plurality of external buckles 3 with adjustable sizes are welded on the outer surface of the main rod body 1, a plurality of internal buckles 2 are welded inside the main rod body 1, a test wire 4 with a surface made of an insulating material is embedded on the internal buckles 2, one end of the test wire 4 is connected with the top end of the main rod body 1, and the other end of the test wire 4 extends out of the tail of the main rod body 1.

As a further alternative to this embodiment, the main rod body 1 is made of plastic tape or bakelite.

The utility model discloses an application principle does: in the AC voltage withstand test of the transformer, a small number of insulating rods are needed to fix the voltage-applying wire, so that the purpose of suspending the voltage-applying wire is achieved. Therefore, when fixing the insulator spindle, can find the cylinder or other positions that are used for fixed insulator spindle, the size of external buckle 3 is adjusted to accessible cylinder or fixed position's size to reach the purpose of fixed insulator spindle, simultaneously, also can fix the pressure line simultaneously through external buckle 3 on insulator spindle upper portion. When the testing step of square wave beating is needed in the partial discharge test of the transformer, the problem of poor contact with the head end of the insulating rod due to the fact that the testing wire is not fixed at the outer part of the insulating rod is solved through the testing wire fixed by the built-in buckle 2 of the insulating rod.
