Description

Electrical Equipment Upright Lead Hanging Ground Wire Conductor End Installer

technical field

The utility model relates to a conductor end installer for hanging a grounding wire on an upright lead wire of electrical equipment.

Background technique

Most of the newly invested 500 kV substation equipment is HGIS and GIS equipment, and the lead wires of the line outlet bushings are vertical leads. There is no suitable and dedicated installation position for the conductor end of the ground wire, which makes it impossible to connect the ground wire or the position of the ground wire is unreasonable (some Hanging line outlet voltage transformer and lightning arrester), which affects the safety arrangement and personal safety during equipment maintenance, and the existing grounding wire conductor end is in the form of clamping and hanging as shown in Figure 1, which has a narrow scope of application. Only the horizontal device can be hooked, and because it is only roughly clamped by the clamping piece, it cannot maintain sufficient clamping force for different models and shapes of clamped objects.

Contents of the invention

Purpose of the utility model: The utility model provides a conductor end installer for the upright lead wire of electrical equipment to be connected to the ground wire, and its purpose is to solve the existing problems in the past.

Technical solutions:

An installer for the vertical lead wire of electrical equipment to hang the conductor end of the ground wire, which includes an arc-shaped outer bracket, and is characterized in that: an elastic clamping device is arranged in the arc-shaped opening of the arc-shaped outer bracket, and the elastic clamping device includes two upper poles and a plurality of card wheels with bayonet teeth; the card wheels are arranged on the horizontal support rod through the rotating shaft, and the horizontal support rod is connected with the inner side of the arc opening of the arc-shaped outer bracket through the top spring, and the multiple card wheels are divided into two rows The two rows of card wheels are arranged on the left and right sides of the arc-shaped opening, and each row of card wheels is arranged in a row from top to bottom; the adjacent upper and lower card wheels in each row are connected by movable joints to form a chain structure; each row The uppermost card wheel in a row is movably connected with the bottom end of the upper strut through a rotating shaft, and the upper end of the upper strut

The tops of the two upper struts are flexibly connected by clamping torsion springs.

A tension spring is arranged between the two upper support rods.

A plurality of locking teeth on the locking wheel are evenly arranged along the circumferential direction.

The bayonet is a triangular structure with the point facing outward.

The bottom of the arc-shaped outer bracket is provided with a straight rod, and the straight rod and the arc-shaped outer bracket are movably connected by a rotating shaft, and the rotation of the rotating shaft makes the straight rod and the plane where the arc-shaped outer bracket is located perpendicular.

Advantages and effects:

The utility model provides an installer for the conductor end of an upright lead wire of electrical equipment to be hung with a ground wire, which is not only suitable for horizontal lead wire installation, but also suitable for the installation of various vertical lead wires in substations. Solve the problem of overheating of the ground wire conductor end installer on the conductive lead wire and in the electromagnetic field environment. It solves the problem that there is no suitable and dedicated installation position for the ground wire conductor end of the vertical lead wire, which causes the problem that the ground wire cannot be hung or the position of the ground wire is unreasonable (some hang the voltage transformer and lightning arrester at the line outlet), and ensure personal safety. It also solves the problems that the conductor end is easily broken and the transparent sheath is easily damaged when the vertical lead wire is connected to the ground wire.

The utility model adopts the multi-point clamping form of the elastic multi-card wheel, which makes it suitable for clamped objects of various shapes. At the same time, the multi-point clamping form makes the clamping more reliable and increases the stability of use.

detailed description:

The utility model provides an installer for the conductor end of the vertical lead wire of electrical equipment to hang the ground wire, which comprises an arc-shaped outer bracket 1, and an elastic clamping device is arranged in the arc-shaped opening of the arc-shaped outer bracket 1, and the elastic clamping device includes two upper Strut 2 and a plurality of card wheels 4 with bayonet teeth 3; the card wheels 4 are arranged on the lateral support rod 5 through the rotating shaft, and the lateral support rod 5 is connected with the inner side of the arc opening of the arc-shaped outer bracket 1 through the tension spring 6 , a plurality of card wheels 4 are divided into two rows, and the two rows of card wheels 4 are arranged on the left and right sides of the arc mouth, and each row of card wheels 4 is arranged in rows from top to bottom; the adjacent upper and lower card wheels in each row The wheels 4 are movably connected by movable joints 7 to form a chain structure; the uppermost card wheel 4 in each row is movably connected with the bottom end of the upper strut 2 through a rotating shaft, and the upper end of the upper strut 2

The tops of the two upper struts 2 are flexibly connected by clamping torsion springs 8 .

A tension spring 9 is arranged between the two upper struts 2 .

A plurality of locking teeth 3 on the locking wheel 4 are evenly arranged along the circumferential direction.

The locking tooth 3 is a triangular structure with the point facing outward. The function of the locking teeth 3 is to increase the clamping friction.

The bottom of the arc-shaped outer bracket 1 is provided with a straight rod 10, and the straight rod 10 and the arc-shaped outer bracket 1 are flexibly connected by a rotating shaft 11, and the rotation of the rotating shaft 11 makes the plane where the straight rod 10 and the arc-shaped outer bracket 1 are located vertical. 12 among the figure is clamped object.

When the installer is in use, the object to be clamped is stretched between two rows of card wheels 4 for clamping, because there are multiple card wheels 4, and they are connected elastically by the tensioning spring 6, so that the object to be clamped along its Even clamping of the circumference part will achieve uniform multi-point clamping of the clamped object, instead of just two points of left and right clamping as in the past, and its clamping stability is greatly improved. On the other hand, the clamping torque Both the spring 8 and the tension spring 9 can further enhance the firmness of clamping, and when the clamped object is placed horizontally, as shown in Figure 2, it is necessary to rotate the arc-shaped outer bracket 1 so that the straight rod 10 and the arc-shaped outer bracket The plane where 1 is located is vertical, and then the object to be clamped can be clamped on the side. This structure makes it more widely used.
