Abstract
The utility model provides a dry high-voltage wall-penetrating bushing which is characterized in that a wiring board is connected with a conducting rod, an insulating layer is arranged outside the conducting rod, and a flange is arranged in the middle part outside the insulating layer. The insulating layer is wound by dry solid insulating material band and aluminum foil according to the coaxial capacitor dividing structure with uniform thickness, uniform capacitance, and uniform distance; insulating liquid is filled in the insulating layer, a silicone rubber umbrella skirt is sleeved outside the insulating layer. The utility model has the advantages that the insulating layer is an insulating structure with uniform thickness, uniform capacitance and different screen length, the field intensity distance is even, the outer insulating performance and the water-adding performance are good, and the service life is long.
Description
Technical field
The utility model relates to a kind of dry-type high-voltage wall bushing, is applicable to 220KV and following AC electric power systems, makes the wall bushing of the high voltage power transmission bus insulation usefulness of entering the room through walls.
Background technology
Its insulation property of high-voltage wall bushing are poor at present, conductivity and poor radiation, and insulating barrier tool air-gap, partial discharge quantity is big, dielectric loss rate height.
Summary of the invention
Its purpose of the utility model is: a kind of dry-type high-voltage wall bushing is provided, its insulating barrier be equal thickness, etc. electric capacity, do not wait the screen long insulation system, field strength distribution is even, its external insulation characteristic is good and hydrophobicity is good, and long service life.
The utility model is achieved in that a kind of dry-type high-voltage wall bushing, comprise: terminal block links conducting rod, insulating barrier is provided with outside the conducting rod, ring flange is provided with the outer interposition of insulating barrier, its insulating barrier is dry solid insulation material band and aluminium foil, divide the equidistant coileds of electric capacity such as laminated structure equal thickness by ganged condenser, fill iknsulating liquid in it, the silicon rubber full skirt is set in the insulating barrier outside.Its conducting rod is located in the person in charge, and end also was fixedly connected with it before grading shield was provided with insulating barrier.Its zero screen outlet is communicated with ring flange, and its iknsulating liquid is identical with dry solid insulation material band and aluminium foil dielectric constant.
The utility model dry-type high-voltage wall bushing is made up of contact tube, main insulation, grading shield, full skirt, spacer flanger, binding post etc., main insulation is formed by ganged condenser dividing potential drop structural design by poly-band of dry solid insulating material and aluminium foil, for equal thickness, etc. electric capacity, do not wait the long insulation system of electric screen, insulating barrier all adopt half-stack package around, inside is full of the iknsulating liquid close with the insulating tape dielectric constant, to get rid of gas, improve local discharging level, external insulation adopts the silicon rubber full skirt, has good insulation performance characteristic and hydrophobicity.Contact tube is copper pipe or stainless steel tube, have good electrical conductivity and thermal diffusivity, therefore to have field intensity even for this product, do not have that oil, no gas, low office are put, low dielectric loss, anti-filth, prevent that electricity is led, characteristics such as non-maintaining, be desirable high pressure wall isolation equipment, this product structure design novelty, manufacturability is strong, is fit to standardization, generalization, mechanization production.
Elaborate its structure with accompanying drawing in conjunction with the embodiments:

Embodiment
Its structure of the utility model is shown in Fig. 1-2, a kind of dry-type high-voltage wall bushing, comprise: terminal block 1 links conducting rod 6, insulating barrier 7 is provided with outside the conducting rod 6, ring flange 4 is provided with insulating barrier 7 outer interpositions, and its insulating barrier 7 divides the equidistant coileds of electric capacity such as laminated structure equal thickness for dry solid insulation material band and aluminium foil 701 by ganged condenser, fill iknsulating liquid 702 in it, silicon rubber full skirt 3 is set in insulating barrier 7 outsides.Its conducting rod 6 is located at and is responsible in 5, and end also was fixedly connected with it before grading shield 2 was provided with insulating barrier 7.Its zero screen outlet 8 is communicated with ring flange 4, and its iknsulating liquid 702 is identical with dry solid insulation material band and aluminium foil 701 dielectric constants.
This utility model is to realize by following approach:
As shown in Figure 1; terminal block 1 is installed in an end of capacitance plate 7; silicon rubber full skirt 3 is sleeved on capacitance plate or the insulating barrier 7, does the protection of its exterior insulation, avoids it to make moist and increases the creepage distance that compares; grading shield 2 is as capacitance plate formula insulating barrier grading shield; play the uniform electric field effect, ring flange is enclosed within on the capacitance plate, the mounting panel when through walls; this type is simple in structure, is easy to install.
