Description
Technical field
The utility model relates to a kind of insulating sleeve of being convenient to use through walls.
Background technology
Known according to the characteristic of electric power system, often use insulating material in electric power system, to reach the purpose of insulation, the insulating material used in electric power system can be referred to as electrical insulating material.Definition by standard GB/T 2900.5 regulation insulating material is: " being used for making the material of device insulation on electric ", the material that namely can stop electric current to pass through, its resistivity is very high, usually in the scope of 10～10 Ω m.As the insulating material used in motor, be arranged on conductor insulating material on every side by the turn-to-turn isolation and keep apart with the stator core of ground connection, to guarantee the safe operation of motor.
In electric power system, usually, at the sheathed insulating sleeve in the outside of cable, play the effect of radial insulation; In the use procedure of insulating sleeve, because the frequent existence of cable need to be through the situation of body of wall, therefore insulating sleeve also needs accordingly through body of wall, existing insulating sleeve is through after body of wall, without any other measures, insulating sleeve is fixed, therefore have loosening situation, can affect the effect that is connected of whole cable and other electric equipments when serious; Therefore design and a kind ofly be convenient to use through walls, and can not become flexible after through walls, can firmly be fixed on body of wall, improve the insulating sleeve of the connection effect between cable, be problem demanding prompt solution.
The utility model content
The purpose of this utility model is to provide a kind of insulating sleeve of being convenient to use through walls, and this insulating sleeve is convenient to use through walls, and can not become flexible after through walls, can firmly be fixed on body of wall, improves the connection effect between cable.
The utility model is achieved through the following technical solutions: a kind of insulating sleeve of being convenient to use through walls mainly consists of sleeve body, guide rod and fixture; Described sleeve body and guide rod are hollow structure, and guide rod runs through the inside that is arranged on sleeve body, and described fixture is arranged on the outer wall of sleeve body.When using insulating sleeve to carry out when through walls, only need to offer in advance a wall hole be complementary with the sleeve body size on body of wall, then sleeve body is passed to body of wall, by fixture, insulating sleeve is fixed on the wall hole of body of wall afterwards, then cable is got final product through guide rod, whole installation process is simple, and insulating sleeve not there will be loosening phenomenon after through walls, can firmly be fixed on body of wall, improve the connection effect between cable.
Further, in order to play better fixed effect, fixture of the present utility model is arranged on the center of sleeve body outer wall.
Further, described fixture clamping or be glued on the outer wall of sleeve body, but mounting means is not limited to clamping or glueds joint two kinds of modes, also can select separately other mounting meanss according to actual conditions, such as bolt connection etc.
As a kind of optimal way of the present utility model, described fixture is flange, this flange is by clamping or be glued on the outer wall of sleeve body, when insulating sleeve, through after body of wall, only need can realize by being fixed together between flange and body of wall the fixing of insulating sleeve.
As another kind of optimal way of the present utility model, described fixture is two clamps that are symmetricly set on the sleeve body outer wall, and all runs through on clamp to be provided with and be fixedly connected with hole.This clamp is to be movably arranged on the outer wall of sleeve body, and between clamp and sleeve body, gap should be as far as possible little, and only need meet clamp can break away from and get final product with sleeve body; When sleeve body is passed the wall hole on body of wall, between clamp and sleeve body, separate, sleeve body is through behind the wall hole, two clamps are penetrated from the two ends of sleeve body respectively, then be pressed on the both sides of body of wall, after location positioning, bolt is passed and is arranged on the hole that is fixedly connected with on clamp, clamp and body of wall are fixed together, due to the position-limiting action of clamp to sleeve body, can realize the fixing of whole insulating sleeve.
Further, between the outer wall of described guide rod and the inwall of sleeve body, exist gap to form air chamber, the air chamber between guide rod and insulator, as supplementary insulation, can reduce capacitance of bushing, improves corona voltage and the sliding lightning of sleeve pipe and presses.The inwall of described sleeve body is coated with semi-conducting glaze, and is provided with spring leaf on the outer wall of semi-conducting glaze and guide rod.When electric pressure is higher, corona will occur and above-mentioned effect was lost efficacy in the above-mentioned air chamber inside be arranged between guide rod outer wall and sleeve body inwall, at this moment adopt the air chamber short-circuit structure, be coated with semi-conducting glaze at the sleeve body inwall, and connect and make the air chamber short circuit with spring leaf and conductor, in order to eliminate inner corona, thereby make air chamber recover to improve the effect of corona voltage and sliding lightning pressure
Further, be provided with the insulation full skirt on the outer wall of described sleeve body.When the inwall coating semiconductor glaze in sleeve body, and be provided with spring leaf on the outer wall of semi-conducting glaze and guide rod, when eliminating inner corona, but corona and sliding the sudden strain of a muscle still may occur in sleeve pipe, by the insulation full skirt is set on the outer wall of sleeve body, improve the flash-over characteristic of sleeve pipe.The number of described insulation full skirt is at least two, and is symmetrical set on its outer wall along the center of sleeve body, thereby plays the effect of better raising sleeve pipe flash-over characteristic.
Further, the material of described sleeve body is preferably pottery or insulating resin, thereby plays the effect of insulation, but the material of sleeve body is not limited to pottery or insulating resin, also can select separately other insulating material according to actual conditions.The material of described guide rod is steel material, but the material of guide rod is not limited to steel material, also can select separately other materials according to actual conditions.
Further, described end cap is installed on the inwall of sleeve body, thereby is convenient to the installation of end cap and the dismounting in when maintenance.Be provided with seal between the inwall of described end cap and sleeve body, thereby can make the zone between the outer wall of the inwall of sleeve body and guide rod form a seal cavity, and then the effect that improves air chamber, significantly reduce capacitance of bushing, improve corona voltage and the sliding lightning of sleeve pipe and press.
The utility model compared with prior art, the advantage had and beneficial effect:
1, the utility model by arranging fixture on the outer wall of sleeve body, realize fixing between insulating sleeve and body of wall by this fixture, thereby make insulating sleeve can not become flexible after through walls, can firmly be fixed on body of wall, improve the connection effect between cable.
2, the utility model is by being arranged to insulating sleeve two parts of mutual sheathing, be positioned at outside sleeve body, and be arranged on the inner guide rod of sleeve body, when using, only cable need be passed from the inside of guide rod, can realize the insulation effect of cable, its mount scheme, and insulation effect is good.
3, gap is set between the outer wall of the utility model by the inwall by sleeve body and guide rod and forms air chamber, can reduce capacitance of bushing, improve corona voltage and the sliding lightning of sleeve pipe and press; By the insulation full skirt is set on the outer wall of sleeve body, improve the flash-over characteristic of sleeve pipe; By between the inwall in end cap and sleeve body, being provided with seal, thereby further improved the effect of air chamber.
