Abstract
The utility model discloses a generating line shielding insulation support, its characterized in that is equipped with rectangular mounting panel, and the interval is equipped with three insulation support of group uniformly on the mounting panel, and three insulation support's of group axis just is parallel to each other with the mounting panel is perpendicular, is equipped with the mounting hole to the peripheral interval of mounting panel, is equipped with the strengthening rib between mounting hole and insulation support, the utility model discloses an integral type structure that high insulating's epoxy vacuum casting formed has following advantage: firstly, this mother wire sleeve is insulating reliable, and inside field distribution is even, does not produce electromagnetic eddy currents, the problems of discharging such as corona and leakage current can not appear, has solved flashover, easy puncture that present high tension switchgear divides the body structure to lead to the fact owing to the insulation support three -phase, life low grade defect, two is rational in infrastructure, simple to operate, and it has the not circular cluster parachute of co -altitude to cross ferry periphery design at the generating line, has increased surperficial creepage distance for the sheathed tube reliability further is protected.
Description
Technical field
The utility model relates to power system power supply device, specifically a kind of bus shield insulating sleeve on high voltage switchgear.
Background technology
As everyone knows, bus shield insulating sleeve is the primary insulation parts of high-tension switch cabinet, that copper busbar enters the vitals carrying out connecting transition between high-tension apparatus and high-tension apparatus, its insulation quality directly affects the insulation property of switch cubicle entirety and the reliability of safe operation, present stage, insulated sleeve of high-tension switch cabinet was that three-phase is split type, the high voltage bus of each phase is equipped with an insulating sleeve, insulating sleeve is the inner sleeve and outer tube suit formation that adopt high insulating material to make, inner sleeve and outer tube not only require coaxial line, and dimension precision requirement is high, often because the mounting arrangements uniformity coefficient of high voltage bus conductor is inadequate in reality, easily cause the non-uniform electric on conductor, electric charge forms electromagnetic eddy under the guiding of non-uniform electric field, inside pipe casing is caused to occur electric discharge, the phenomenon of flashover and insulation breakdown, thus cause the operation that whole switch cubicle can not be safe and reliable.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provide a kind of insulation property reliable, insulating part Electric Field Distribution is even, the bus shield insulating sleeve of convenient and flexible installation.
The utility model can be reached by following measure:
A kind of bus shield insulating sleeve, it is characterized in that being provided with rectangular mounting panel, mounting panel is provided with evenly and at intervals three groups of insulating sleeves, the axis of three groups of insulating sleeves is vertical with mounting panel and be parallel to each other, be provided with installing hole to mounting panel peripheral intervals, between installing hole and insulating sleeve, be provided with reinforcement.
The utility model is provided with front reinforcement and rear reinforcement, and front reinforcement and rear reinforcement are tangent with the external diameter of three insulating sleeves respectively, to improve the bonding strength of insulating sleeve.
Four corners of mounting panel described in the utility model are respectively equipped with installing hole, mounting panel is provided with the arc reinforcement with installing hole concentric, be provided with in splayed and two symmetrical reinforcements in the middle of arc reinforcement and between adjacent insulating sleeve, to improve the bonding strength of insulating sleeve.
Be respectively equipped with installing hole in the middle of former and later two limits of mounting panel described in the utility model, the both sides of installing hole are provided with the installing hole reinforcement be connected with rear reinforcement with front reinforcement, to improve the bonding strength of insulating sleeve.
The utility model adopts the integral structure of the epoxide resin vacuum cast of high-insulativity, have the following advantages: one is that the insulation of this bus casing is reliable, internal electric field is evenly distributed, do not produce electromagnetic eddy, there will not be the electric discharge such as corona and leakage current problem, solve flashover that existing high-tension switch cabinet causes due to insulating sleeve three-phase separate body structure, easily puncture, the defects such as useful life is low; Two is rational in infrastructure, easy for installation, is designed with the circular cluster parachute of differing heights, adds surface creepage distance in bus transition mouth periphery, and the reliability of sleeve pipe is protected further.
