An electric disassembly and assembly insulating operating rod

Abstract

The utility model belongs to the technical field of insulating operating rods, in particular to an electric disassembly and assembly insulating operating rod, comprising a telescopic insulating rod with a hollow structure, and a bracket head arranged on the top of the telescopic insulating rod, and also comprising an upper double-tongue component and a lower double-tongue component arranged on the bracket head, and a hammering component arranged on the bracket head. The bracket head is pushed to the top of the cable through the telescopic insulating rod, and then the bracket head is moved downward. The cable passes through the lower double-tongue component and enters the interior of the bracket head, and then the upper lever is toggled to rotate. The upper lever pulls the limit slider to slide inside the limit slide cylinder through a pull rope and a tension spring, and stretches the tension spring. At this time, the cable is clamped between the hammering components, and then the force applied to the upper lever is released. At this time, the tension spring is reset to exert an outward impact on the limit slider, so that the hammer head on the limit slider breaks the ice layer on the outer layer of the cable, thereby ensuring the grounding effect and improving safety.

Description

Technical Field

[0001] The utility model belongs to the technical field of insulating operating rods, and in particular relates to an electrically disassemblyable insulating operating rod. Background Art

[0002] With the rapid development of social economy, the demand for electricity is growing, the number of substations is increasing, the number of primary equipment such as circuit breakers, disconnectors, voltage transformers, current transformers, etc. is increasing, and the maintenance and testing of these primary equipment is also increasing. In order to ensure safety, it is usually necessary to use a high-voltage insulating operating rod to hang the ground wire or remove the ground wire of the corresponding equipment. In the process of hanging the ground wire or removing the ground wire, it is also necessary to frequently pull and close the disconnector or the grounding disconnector. However, the disconnector or the grounding disconnector is often not operated properly due to various reasons. At this time, it is necessary to use a high-voltage insulating operating rod to make secondary adjustments to the moving and static contacts. According to incomplete statistics, there are more than 2,000 disconnectors or grounding disconnectors of Shunyi Power Grid Company alone. It can be seen that the high-voltage insulating operating rod plays an important role in the actual work of the substation;

[0003] When the current insulated operating rod is used in the cold winter in the north, due to the ice layer on the transmission line, if the ice layer at the connection position cannot be removed or penetrated during the grounding operation, it will affect the grounding effect and cause great safety hazards.

[0005] The hammering assembly comprises a pair of left extrusion heads and a pair of right limit slide cylinders arranged on the bracket head, and an upper lever and a lower lever movably arranged on the telescopic insulating rod.

[0006] As an electric disassembly and assembly insulating operating rod of the utility model, preferably, both right limit slide cylinders are provided with limit sliders, the top of the limit slider is provided with a hammer head, and the tail end of the limit slider is provided with a tension spring.

[0012] The bracket head is pushed to the top of the cable through the telescopic insulating rod, and then the bracket head is moved downward. The cable passes through the lower double-tongue assembly and enters the interior of the bracket head. Then the upper lever is turned to rotate. The upper lever pulls the limit slider through the pull rope and the tension spring to slide inside the limit slide cylinder and stretch the tension spring.

At this time, the tension spring resets the limit slider to exert an outward impact force, so that the hammer head on the limit slider breaks the ice layer on the outer layer of the cable, ensuring the grounding effect and improving safety.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 As shown;

[0027] An electric disassembly and assembly insulating operating rod comprises a telescopic insulating rod 1 with a hollow structure and a bracket head 2 arranged on the top of the telescopic insulating rod 1.

[0028] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the current insulating operating rod is used in the cold winter in the north. Due to the ice layer on the transmission line, when the grounding wire operation is performed, if the ice layer at the connection position cannot be removed or penetrated, it will affect the grounding effect and cause great safety hazards." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a hammering component 5 is added on this basis.

[0029] like Figure 1-4 As shown in the figure;

[0030] In combination with the above content, in order to facilitate the removal of the ice layer at the connection position and ensure the grounding effect, it also includes an upper double-tongue component 3 and a lower double-tongue component 4 arranged on the bracket head 2, and a hammering component 5 arranged on the bracket head 2;

[0031] The hammering assembly 5 includes a pair of left extrusion heads 51 and a pair of right limit slide cylinders 52 arranged on the bracket head 2, and an upper lever 53 and a lower lever 54 movably arranged on the telescopic insulating rod 1.

[0032] In an optional embodiment, a limiting slider 521 is disposed inside each of the two right limiting slide cylinders 52 , a hammer head 522 is disposed at the top of the limiting slider 521 , and a tension spring 523 is disposed at the tail end of the limiting slider 521 .

[0033] In an optional embodiment, the right limiting slide cylinder 52 matches the limiting slider 521 , and the limiting slider 521 slides left and right inside the limiting slide cylinder 52 , and a pull rope 524 is provided at the tail end of the tension spring 523 .

[0034] In an optional embodiment, the two pull ropes 524 pass through the inside of the telescopic insulating rod 1 and are fixedly connected to the tail ends of the upper lever 53 and the lower lever 54 respectively.

[0035] In an optional embodiment, the upper lever 53 is connected to a tension spring 523 at the tail end of the limiting slider 521 at the lower portion of the bracket head 2 via one of the pull ropes 524 .

[0036] In an optional embodiment, the lower lever 54 is connected to the tension spring 523 at the tail end of the upper limiting slider 521 of the bracket head 2 through another pull rope 524 .

[0037] Working principle of this utility model:

[0038] The bracket head 2 is pushed to the top of the cable through the telescopic insulating rod 1, and then the bracket head 2 moves downward. The cable passes through the lower double-tongue component 4 and enters the interior of the bracket head 2. Then the upper lever 53 is rotated. The upper lever 53 pulls the limit slider 521 to slide inside the limit slider 52 through the pull rope 524 and the tension spring 523, and stretches the tension spring 523. At this time, the cable is clamped between the hammering components 5, and then the force applied to the upper lever 53 is released. At this time, the tension spring 523 resets the limit slider 521 to an outward impulse, so that the hammer head 522 on the limit slider 521 breaks the ice layer on the outer layer of the cable, ensuring the grounding effect and improving safety.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
