Abstract

The utility model relates to devices used in the electric power industry, in particular for twisting connecting oval clamps (COM) for self-supporting insulated wires (SIP-3). The objective of the utility model is to expand the arsenal of technical means used for twisting connecting oval clamps (COM) for self-supporting insulated wires (SIP-3). The technical result consists in the speed and quality of twisting the oval clamp COM on a self-supporting insulated wire (SIP-3). The problem is solved, and the technical result is achieved by creating and using a device consisting of a base made of a lightweight steel square profile, to one side of which an emphasis for fixation (COM) is welded, and on the other - a lock nut, a steel rod with an emphasis is inserted into the base for fixing (COM) on one side and with the other adjustable bolt, which is screwed into the lock nut for high-quality fixation of the oval clamp (COM).

Description

The utility model relates to devices used in the electric power industry, in particular for twisting connecting oval clamps (COM) for self-supporting insulated wires (SIP-3).

When installing overhead power lines, special connecting oval clamps (COM) of different diameters are used to connect self-supporting insulated wires.

To connect a self-supporting insulated wire (SIP-3), the wire is peeled from the insulating coating to a distance equal to the length of the connecting oval clamp (COM), then inserted from both sides with the cleaned ends of the wires into the oval clamp and twisted using special devices. Known devices for twisting connecting oval clamps MI-230K [Device for twisting MI-230K (Electronic resources. https://yandex.ru/video/touch/preview/?text=%D0%9C%D0%98%20230%D0 %9A&path=yandex_search&parent-reqid=1664265162192104-3597507900491256888-sas6-5247-e4e-sas-17-balancer-8080-BAL-3470&from_type=xl&filmId=21382877444864189075, -skruchivaniya-provodov -mi-189k.html)].

The disadvantages of this device are:

the complexity of the process, twisting the oval clamp COM in the field conditions due to the inability to install the device on a flat surface;

significant weight and bulky design of the device.

The objective of the utility model is to expand the arsenal of technical means used for twisting connecting oval clamps (COM) for self-supporting insulated wires (SIP-3).

The technical result consists in the speed and quality of twisting the oval clamp COM on a self-supporting insulated wire (SIP-3).

The problem is solved, and the technical result is achieved by creating and using a device consisting of a base made of a lightweight steel square profile, to one side of which an emphasis for fixation (COM) is welded, and on the other a lock nut, a steel rod is inserted into the base, with an emphasis for fixing (COM) on one side and with the other adjustable bolt, which is screwed into the lock nut for high-quality fixation of the oval clamp (COM).

The claimed device for twisting connecting oval clamps (COM) for self-supporting insulated wires (SIP-3) is explained using:

fig. 1 - side view;

fig. 2 - device in operation;

fig. 3 - photo of the device.

The device consists of a base (1) made of a lightweight square profile. A lock nut (2) is welded to the profile on one side, and a stop (3) for fixing (COM) on the other. A steel rod (4) is inserted into the base with a stop (5) for fixing (COM) on one side, and an adjusting screw (6) on the other, which is screwed into the lock nut (2) for high-quality fixation of the oval clamp (7) (COM).

The operation of the device for twisting connecting oval clamps (COM) for self-supporting insulated wires (SIP-3) is carried out as follows. The electrician strips the wire from the insulating coating to a distance equal to the length of the connecting oval clamp (7) (COM), then inserts it from both sides with the stripped ends of the wires into the oval clamp, the device is installed on the clamp from both sides using the adjusting screw (6) and the oval clamp is clamped between stops (3), (5) and twist in opposite directions from each other.

Using the device, it is possible to quickly and efficiently twist the oval clamp (COM) for connecting self-supporting insulated wires (SIP-3).

The introduction of this device makes it possible to refuse the use of the MI-230K device when connecting self-supporting insulated wires (SIP-3).

For the declared design, working drawings, strength calculations were made and a prototype was made, which was successfully tested when twisting the connecting oval clamps (SOM) for self-supporting insulated wires (SIP-3) on the 10 kV overhead line feeder Sever in the Gryazovets LPUMG of Gazprom transgaz Ukhta ".

Claims (1)

A device for twisting connecting oval clamps (COM) for self-supporting insulated wires SIP-3, consisting of a base made of a lightweight steel square profile, to one side of which an emphasis is welded for fixing the COM, and on the other - a lock nut, a steel rod with stop and adjustable bolt, which is screwed into the locknut.
