Embodiment 1

[0040] The 10~220kV multifunctional insulating operating rod includes a plurality of insulating rods, and also includes a plurality of rod heads, and a connecting mechanism for connecting the rod heads, and the rod heads are movably connected to the head of the insulating rod through a connecting structure.

[0041] Wherein, the club head can be made into various club heads in the prior art, such as Figure 1~Figure 4 shown.

[0042] The connecting mechanism itself can be fixed on the head of the insulating rod, or be movably connected to the head of the insulating rod. The connection mechanism itself can adopt connection methods in the prior art, such as: bolt connection, screw connection and the like. It is preferably connected by snap fit.

[0043] The snap-fit ​​connection is as follows: a connecting buckle is provided at the end of the rod head, and an outwardly protruding protrusion is provided at the bottom of the buckle; the connecting mechanism includes a cylindrical...

Embodiment 2

[0050] This embodiment proposes an improved solution on the basis of Embodiment 1.

[0051]On the basis of the practical application of Example 1, a card slot is added on the stopper.

[0052] In Example 1, under the double action of the metal pressure piece and the stopper, the connecting buckle will not be displaced in the vertical direction, but in the horizontal direction, it will be displaced in a small range under the condition of external force interference .

[0053] Add a card slot on the stopper, such as Figure 10 As shown, the protruding portion of the connecting buckle can be accommodated in the slot, limiting the displacement of the connecting buckle in the horizontal direction.

Embodiment 3

[0055] On the basis of the foregoing two embodiments, a technical solution for improving the connection and fastening effect between two insulating rods is proposed.

[0056] Most of the traditional insulating rods are connected by simple bolts, which is prone to gaps, resulting in the phenomenon of "bending" of the insulating rod when lifting the rod. Doing this often will reduce the life of the insulating rod.

[0057] A reinforcing mechanism is added at the joint of the two insulating rods; the reinforcing mechanism is independent from the connecting mechanism between the two insulating rods, and the role of the reinforcing mechanism is to eliminate the problem of loosening of the joint caused by threaded connection or snap-fit ​​connection.

[0058] The reinforcing mechanism can adopt methods such as locking buckles and positioning pins, and preferably adopts the method of metal connecting pieces proposed in this embodiment.

[0059] The way of metal connecting piece is a...

Abstract

The invention relates to the field of electrician equipment, specifically to a 10-220kV multifunctional insulating operating rod. The 10-220kV multifunctional insulating operating rod comprises a plurality of insulating rods, a plurality of rod heads and connecting mechanisms for connecting the rod heads, wherein the rod heads are movably connected to the head portions of the insulating rods through connecting structures, the tail portions of the rod heads are provided with connecting buckles, and the bottom of each buckle is provided with an outwardly protruding boss. Each connecting mechanism comprises a cylindrical pedestal, a metallic compressing sheet and a constant force spring, wherein a cylindrical cavity is arranged in the pedestal, the bottom of the pedestal is enclosed, the top end is provided with a circular through hole with a gap, and the central inner wall of the pedestal is provided with a backstop for clamping the boss. The bottom of each constant force spring contacts with the bottom of the cavity, the top end of the constant force spring contacts with the metallic compressing sheet, and the metallic compressing sheet is arranged between the backstop and the constant force spring. The insulating operating rod is upgraded and improved, and the problem that a conventional is monotonous in function and inconvenient to use is solved. The insulating operating rod, cooperating with a plurality of rod heads, is comprehensively compatible with conventional rod heads or tools.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a 10-220kV multifunctional insulating operating rod. Background technique [0002] Insulated operating rod is an indispensable safety tool in the process of power equipment operation and maintenance. It is used for opening and closing isolating switches, hanging and removing grounding wires, high-voltage test wiring of electrical equipment, and checking phases and phase sequences of high-voltage lines. to the insulating lever. The insulating operating rod can effectively isolate the human body from the live parts and possible live parts of the electrical equipment, reducing the occurrence of electric shock accidents. [0003] The situation of the power grid is relatively complicated, old and new substations exist at the same time, and the equipment in the substations varies greatly. From the perspective of circuit breakers, from old-fashioned oil-less circuit breakers to the ...
