Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for electric power equipment, in particular to a buckle-type insulating rod used for measuring insulation resistance. Background Art

[0002] According to the "Electric Power Safety Work Regulations" and "Electric Power Industry Technical Management Regulations" of the People's Republic of China, in order to ensure personal safety and protect equipment from damage, safety measures must be implemented before operating or repairing electrical equipment.

[0003] Insulation resistance is the most basic insulation indicator of electrical lines and equipment, and it can effectively reflect the actual working conditions of the equipment. Before the power plant unit is energized, the operator must measure the insulation resistance of the unit equipment to check the insulation status of the electrical equipment and determine whether the equipment has defects such as aging and leakage, so as to ensure that the unit works in a normal state. When measuring the insulation resistance of high-altitude equipment, it is necessary to use an insulating rod to hang the branch conductor to the measurement position. At present, hydropower stations often use an insulating rod for hanging branch conductors. During operation, only the metal hook is placed on the conductor. There is a risk of misoperation of the insulating rod during the measurement process, causing the rod body to fall, which can easily cause harm to the operator. Therefore, when measuring the insulation resistance of high-altitude equipment, how to ensure the stability of the insulating rod and not fall off has become a problem that needs to be solved urgently.

[0004] In order to solve the above technical problems, it is urgently necessary to provide a snap-on insulating rod for insulation resistance measurement. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a snap-on insulating rod used for insulation resistance measurement to solve the problems raised in the background technology.

[0006] The utility model solves the above technical problems and adopts the following technical scheme: a buckle-type insulating rod used for insulation resistance measurement, comprising a rod body, a metal hook is arranged on the upper end of the rod body, and a telescopic element is installed at the end of the metal hook.

[0007] Preferably, the telescopic element is a groove-shaped structure, the main body of the telescopic element is a telescopic sleeve rod, and connecting buckle strips are arranged at both ends of the telescopic sleeve rod.

[0008] Preferably, anti-slip material is provided on the inner side of the buckle strip.

[0009] Preferably, one end of the metal hook is connected to the rod body, and the other end of the metal hook is connected to a buckle strip at one end of the telescopic element.

[0010] The utility model has the following beneficial effects:

[0011] The utility model solves the problem of unstable hanging of high conductor ends existing in the original hook by improving the metal hook structure at the upper end of the insulating rod, realizes stable operation when measuring insulation resistance at higher positions such as the generator outlet side and the low-voltage side of the transformer, so that the branch wire of the insulation meter can be stably hung at the measuring position of conductors with different thicknesses, ensuring the smooth progress of insulation measurement, thereby reducing safety hazards and ensuring the life safety of operating personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the telescopic element structure of the utility model. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0015] See also Figure 1 to Figure 2 A snap-on insulating rod for insulation resistance measurement includes a rod body 1, a metal hook 2 is arranged at the upper end of the rod body 1, and a telescopic element 3 is arranged at the end of the metal hook 2. This design can meet the needs of operating conductors of different thicknesses and ensure the smooth operation of insulation measurement.

[0016] Preferably, the telescopic element 3 is a slot-shaped structure, the main body of the telescopic element 3 is a telescopic sleeve rod 3.1, and connecting buckle strips 3.2 are arranged at both ends of the telescopic sleeve rod 3.1. This design can adjust the length of the telescopic sleeve rod arbitrarily according to the width of the conductor during use, which is convenient for operation. The buckle strips at both ends of the telescopic element are convenient for one end to be connected with the metal connecting rod, and the other end can buckle the conductor during use to play a stabilizing role.

[0017] Preferably, the inner side of the buckle strip 3.2 is provided with anti-skid material. Providing the anti-skid material on the inner side of the buckle strip can prevent the conductor from falling off and deviating when hooking it, thereby reducing safety hazards.

[0018] Preferably, one end of the metal hook 2 is connected to the rod body 1, and the other end of the metal hook 2 is connected to the buckle strip 3.2 at one end of the telescopic element 3. The design of the metal hook increases the operating space and can more flexibly measure conductors of different sizes.

[0019] The working principle of this embodiment is as follows:

[0020] When the utility model is in use, during operation, the height of the telescopic sleeve rod is adjusted according to the conductors of different thicknesses. After the adjustment is completed, the insulated meter branch wire is clamped at the metal end of the side of the buckle strip, and then the metal connecting rod is hung to the measuring conductor position, and it is pulled back to make the telescopic element clamp the conductor, and the operation is completed after confirming that it is clamped tightly without looseness.

[0021] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
