Description
Technical Field
The utility model relates to a wall bushing, in particular to a porcelain bushing for a high-voltage electrostatic oil smoke removing device.
Background
The main structure of the high-voltage electrostatic lampblack removing equipment comprises an equipment shell, an electric field and a peripheral direct-current power supply, wherein the electric field and the peripheral direct-current power supply are arranged in the shell, a connecting cable of the electric field and the peripheral direct-current power supply needs to penetrate through the equipment shell.
The prior art designs of the above-described wall bushing are used in an environment where one end is exposed to outdoor atmospheric conditions and the other end is exposed to the interior of a room, so that the end exposed to the interior of the room has lower fouling performance and lower creepage distance than the end exposed to the exterior of the room.
The service environment of the wall bushing of the high-voltage electrostatic lampblack removing equipment is opposite to the design conditions of the prior art, oil stains, particles and a large amount of water vapor (especially under wet static conditions) exist in the shell of the high-voltage electrostatic lampblack removing equipment, namely the environment condition of one end of the wall bushing exposed indoors (in the equipment shell) is worse than that of the other end exposed outdoors, and in actual operation, the equipment fault is caused by flashover breakdown after the oil stains and the water vapor are adhered to one end of the wall bushing indoors, so that the production of enterprises is influenced, and the operation and maintenance cost is increased.
Disclosure of Invention
To the problem that exists among the prior art, the utility model aims to provide a porcelain bushing's technical scheme.
The utility model relates to a porcelain bushing, including an uncovered cup porcelain bushing, this uncovered cup porcelain bushing appearance is hollow round platform type, the inside and outside surface of porcelain bushing is all smooth and local or all covers high resistance layer like glaze to strengthen its mechanical strength, thermal stability, dielectric strength and be convenient for wipe away characteristics such as washing, the fixed orifices of line hole and symmetrical arrangement has been put to the bottom of cup central point of porcelain bushing, and the installation ear more than two is arranged to rim of a cup edge symmetry, has the bolt hole on the installation ear, and an electric conductor (like the copper bar) passes the line hole is fixed on the axis position of porcelain bushing by the mounting, and the size of crossing the line hole just holds the electric conductor and passes, and rim of a cup one side electric conductor is indoor inner, and bottom of a cup one side electric conductor is indoor outer end, and there are indoor inner wiring hole and outdoor end wiring hole respectively at the electric conductor both ends.
The utility model discloses indoor inner electric conductor and the nearly unsettled arrangement of insulator, its creepage distance is difficult for taking place the flashover because of the environment is abominable greatly, can reduce high-voltage static oil smoke removal equipment fault rate and reduce fortune dimension cost.

Detailed Description
The invention will be further explained with reference to the drawings in the following description:
a porcelain bushing comprises an open cup-shaped porcelain bushing 20, wherein the open cup-shaped porcelain bushing 20 is in a hollow round table shape, the inner surface and the outer surface of the porcelain bushing are smooth, and high-resistance layers such as glaze are partially or completely covered on the inner surface and the outer surface of the porcelain bushing to enhance the mechanical strength, the thermal stability, the dielectric strength, the wiping and washing convenience and the like, a wire passing hole 22 and fixing holes 23 which are symmetrically arranged are formed in the center of the bottom of the porcelain bushing 20, more than two mounting lugs 21 are symmetrically arranged at the edge of a cup opening, bolt holes are formed in the mounting lugs 21, a conductive body 10 (such as a copper bar) penetrates through the wire passing hole 22 and is fixed on the axis position of the porcelain bushing 20 through a fixing piece 13, the conductive body 10 just penetrates through the wire passing hole 22, the conductive body on one side of the cup opening is an indoor end, the conductive body on one side of the cup opening is.
In using, the bolt hole size according to 20 rim of a cup edge internal diameters of insulator and installation ear 21 at high voltage static oil smoke removing equipment shell suitable position corresponds the trompil, then will with the bolt the utility model discloses fix on high voltage static oil smoke removing equipment shell, at insulator 20 and equipment shell contact surface coating temperature resistant sealed glue or set up the annular and seal up the pad, the electric field negative pole of high voltage static oil smoke removing equipment couples to electric conductor 10's indoor end wiring hole 12, outdoor end wiring hole 11 couples to peripheral high voltage direct current power.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, all the equivalent changes or modifications according to the features and spirit of the present invention should be included in the claims of the present invention.
