Description

Multifunctional porcelain insulator wire fixing device for insulated conducting wire

Technical Field

The invention relates to a porcelain insulator wire fixing device for an insulated wire.

Background

The insulated wire adopted by the existing distribution line has three problems, namely 1, the insulated wire is easy to be broken by lightning, which is a system problem; 2. the traditional method for binding porcelain insulator of the insulated conductor faces three major problems. Firstly, the time cost is huge, the number of insulator binding of one company per year is about 10 thousands, and the time cost of 6000 hours is needed for each average 3 to 4 minutes. The large time cost results in large labor cost. And secondly, the phenomenon of expansion with heat and contraction with cold in extreme weather is serious, and the phenomenon that the lead falls off due to strong wind happens sometimes. Thirdly, due to the uneven personnel level, the binding process cannot meet the requirements, the lead is easy to fall off, short circuit and ground fault occur, and great potential safety hazard exists. 3. And the partial lines have insulated wires without grounding rings, and can not be connected with the ground wire in an electroscopic mode.

Disclosure of Invention

The invention aims to provide a porcelain bottle wire fixing device for a multifunctional insulated wire, which has a pressure relief function and can be used for hanging a ground wire in an electroscope mode.

The technical solution of the invention is as follows:

the utility model provides a multi-functional insulator is wire fixing device for wire which characterized by: the porcelain insulator comprises an insulating wire clamp coated on the upper part of a porcelain insulator, wherein an insulating cushion block is arranged in a cavity between the upper section of the porcelain insulator and the insulating wire clamp, the insulating cushion block is positioned above an insulating wire placing groove at the upper end of the porcelain insulator, a metal pressing plate is arranged above the insulating cushion block, a fastening nut is arranged above the metal pressing plate, and a fastening screw penetrates through the insulating wire clamp, is in threaded fit with the fastening nut and is pressed on the metal pressing plate; the outer side of the insulating cushion block is provided with a conductive belt; the fastening nut, the fastening screw and the conductive belt are communicated with the circuit; the bottom of the fastening screw rod is provided with a pricker which penetrates through a center hole of the metal pressure plate and a center hole of the insulating cushion block and is used for pricking an insulating layer of the insulated wire placed in the insulated wire placing groove.

The working method comprises the following steps: placing the insulated wire into the insulated wire placing groove, pressing the metal pressing plate downwards by the fastening screw rod, further pressing the insulating cushion block, pressing the insulated wire, further downwards piercing the insulating layer of the insulated wire by the fastening screw rod to realize electrical conduction, and realizing pressure relief by current leakage outside the porcelain bottle through the fastening screw rod, the conductive belt and the fastening nut; the electricity testing hanger is grounded through the grounding ring.

And clamping a metal clamp at the top of the fastening screw rod, connecting the metal clamp with a grounding ring, and realizing the grounding of the electroscopic hanger through the grounding ring.

The invention solves the system problem that the insulated conductor is easy to be broken by lightning stroke; the efficiency and the quality of fixing the lead are improved, and the accidents of lead falling, grounding and short circuit caused by unreliable personnel binding are avoided; the binding time is shortened to 1/8 of the original binding time, and the working efficiency is greatly improved; the robot can be widely applied to robot operation, and a large number of operation procedures are reduced; the fixing device is suitable for fixing the bare conductor and the insulated conductor with 70-300 square and the hardware fitting; compared with the similar products in the market, the novel pressure relief device has the advantages that the special pressure relief function is added, the fixing mode is changed, the working efficiency is improved, the phase color is increased, and the help is brought to the operation and maintenance of the circuit.
