Abstract
The invention discloses a power line lead insulation protecting device which is an insulating pipe sleeved on a bare conductor outside a power line or adopts an insulating pipe and an insulating sleeve sleeved on the bare conductor outside the power line. The insulating pipe is an insulating pipe the opening of which can be fastened or an insulating pipe with the opening of which can be stuck or welded. The adopted insulating sleeve is an insulating material sleeve filled between the insulating pipe and the bare conductor. Insulating seal plugs for sealing a cavity between the insulating pipe and a line lead is additionally installed at both ends of the insulating pipe, a liquid insulating material mixed with a solidifying agent and a foaming agent is injected into the sealed cavity, and the insulating sleeve is formed after mixing reaction and solidification. The position without injecting the insulating material has air insulation. The device can be installed at any bare part of the power line except for a support point; because the dead weight is small, the change on the perpendicularity of the lead is small. The device overcomes the protecting defect of the traditional power line, improves the insulating strength of the power line and can prevent the threatening external factors to the safe transmission of the power line and ensure the safe running of power equipment.
Description
Technical field
The present invention relates to a kind of power circuit protector, especially a kind of power line lead insulation protecting device.
Background technology
Flourish along with electric utility, the safe transmission of electric power is most important.The safe transmission of electric power be unable to do without the security protection of power circuit.For current power circuit, particularly the overhead transmission line of mesohigh is still mostly is to adopt bare circuit, the unsettled of this circuit is by supports such as insulator support, suspention or tractives by shaft tower, and circuit itself is exposed to atmosphere, only can keep limited safety in being unlikely to the safe distance of foreign object discharge, there is no other specific aim safeguard procedures at circuit under the general meteorological condition.Along with the variation of power circuit running environment or the violation invasion of other facility etc., external object near in addition entry-line be unlikely to externally discharge safe distance situation can get more and more, its result often forms the threat to the power circuit safe transmission, even causes serious security incident.
Summary of the invention
The present invention is in order to solve the defective that present power circuit protection exists, a kind of safe power line lead insulation protecting device is provided, can effectively improve the security protection of power circuit, avoid external object near or enter and cause externally discharge and cause serious security incident of circuit.
The technical solution used in the present invention is as follows:
The form that the protection of power circuit is intended taking to install the safe insulation device additional on the lead of power circuit is protected.
A kind of power line lead insulation protecting device is the insulated tube that is placed on the outer plain conductor of power circuit.But this insulated tube is the insulated tube of folding, and the insulation blocking is established at the insulated tube two ends.
Another kind of power line lead insulation protecting device then comprises the insulated tube and the insulating case that are placed on the outer plain conductor of power circuit.But described insulated tube is the insulated tube of folding, and described insulating case is the insulating material sleeve that is filled between insulated tube and the outer plain conductor.Insulated tube and its interior insulating case two ends are provided with the insulation blocking of sealing insulating case.
The above insulated tube is the insulated tube that opening can fasten, and single port snapping or twoport snapping all can.
Described insulated tube is that opening can be bonding or the insulated tube of welding.
The insulating material that described insulating case is filled adopts plastics, resin, rubber, shellac is any or more than one mixture.
The interior external diameter of described insulation blocking cooperates with the outer plain conductor of power circuit and insulated tube respectively or seals, and forms sealed hollow thereby make between lead and insulation tube wall.
Above-mentioned insulated tube opening is fastened, after the bonding or welding, installs the insulation blocking additional, promptly form the wire insulation protector of power circuit, if in insulated tube, recharge the insulating case that constitutes by insulating material, its better protecting effect.The wall thickness of insulated tube can just determine that the length of pipe is looked on-the-spot actual needs and selected according to voltage, and the internal diameter of pipe is greater than line conductor line footpath, but is basic demand with deflecting naturally of envelop line conductor.
This device can be installed at any lead position except that the circuit strong point on the power circuit, and is because its deadweight is little, little to the sag change of circuit.
This device overcomes the protection defective that existing power circuit occurs targetedly, has improved the dielectric strength of power circuit, can avoid extraneous factor to the threat that the power circuit safe transmission produces, and guarantees the safe operation of power equipment.
Description of drawings
Accompanying drawing is the structural representation of second kind of technical scheme of the present invention
Embodiment
Introduce embodiments of the invention below in conjunction with accompanying drawing.
As shown in the figure, this power line lead insulation protecting device comprises insulated tube 2 and insulating case 4, and insulated tube 2 is placed on the outer naked power line lead 1, insulating case 4 places between insulated tube 2 and the line conductor 1, and insulated tube 2 is provided with the insulation blocking 5 that seals insulating case 4 with insulating case 4 two ends.
When power circuit is installed additional protection, but the insulated tube 2 of folding is placed on the outer naked line conductor 1, but the insulated tube 2 general hollow insulated tubes that adopt the opening bracelet of folding, but single port snapping or twoport snapping be (not shown) all, looks actual needs and also can adopt the opening can be bonding or the hollow insulated tube of welding.Opening fastens, after the bonding or welding, the blocking of being made by insulating material 5 is loaded onto at cavity two ends between insulated tube 2 and line conductor 1, external diameter is sealed and matched with line conductor 1 and insulated tube 2 respectively in the blocking 5, make this section line conductor 1 be insulated encirclement, the inner enclosed cavity that has contained line conductor 1 that forms.Before injecting an amount of curing by the set inlet 3 in the upper end of insulated tube 2 in cavity is the insulating material of liquid state, and suitably admix small number of curing agents and blowing agent etc., mixture is stirred, liquid insulating material is selected any or more than one mixture such as plastics, resin, rubber, shellac for use, and curing agent and blowing agent can be by the required adapteds of insulating material.Install port lid sealing inlet 3 then additional, make mixture finish course of reaction in this cavity, the foam of generation solidifies after being full of enclosed cavity, forms insulating case 4.Insulating case 4 is isolated the bigger line conductor of insulated tube 2 and electric field strength 1, has not only strengthened the dielectric strength of this protector, and the steam by the outside intrusion of insulated tube also capable of blocking causes insulation destroyed.
This power line lead insulation protecting device can be installed in the power circuit strong point any exposed position in addition.
To insulated tube 2 and line conductor 1 and insulation blocking 5 contained enclosed cavity do not inject any insulating material, also can be used as power line lead insulation protecting device, first kind of scheme of the present invention that Here it is, but its protection effect is not as injecting the ideal of insulating material.
