Abstract
This invention relates to a connection protection device of capacitor equalizing dry insulated bus bar and terminal. The insulation part is applied with dipped insulation paper with winded epoxy resin and capacitor equalized screens in gap set in the paper layer, a protection layer at the outermost is made up of heat contractible tubes or composite tubes composed of heat contractible tubes and metal tubes.
Description
Technical field
The present invention relates to a kind of electric component, particularly a kind of capacitor voltage equalizing type dry insulation bus and terminal connect protective device.
Background technology
Existing bare bus bar, in use, especially for the compact transformer station of structure, single-phase earthing and phase fault accident take place because of the phase insulation of bus is weak in regular meeting, and reliability is relatively poor; It is dumb that the metal-air enclosed busbar is used, and it is narrow to be suitable for current range, and cable is the cost height then, and can not be according to installation environment and changes shape, and it is convenient inadequately to use.
Summary of the invention
The object of the present invention is to provide a kind of safe and reliable, along even, the anti-corona ability of face field strength distribution capacitor voltage equalizing type dry insulation bus strong, applied widely.
Another object of the present invention is to provide a kind of bus bar terminal strong along even, the anti-corona ability of face field strength distribution, good seal performance to connect protective device, the use of this device can make the bus length of standard specification extend arbitrarily according to installation requirement.
Technology solution of the present invention is: a kind of capacitor voltage equalizing type dry insulation bus, comprise conductor, insulating barrier and overcoat, the two ends that it is characterized in that bus-bars conductor are connected with board-like terminal, the insulating barrier of conductor outside adopts epoxy resin impregnated insulating paper to be entwined, the capacitor voltage equalizing screen is set in the insulating barrier at both ends at interval, the insulating barrier outermost layer is provided with the ground connection electric screen, ground connection electric screen peripheral hardware overcoat.Described overcoat is heat-shrinkable tube or the multiple tube that is made of heat-shrinkable tube and metal tube.The overcoat at bus two ends is outer can be provided with full skirt.Owing to adopted said structure, make this bus have along the strong characteristics of even, the anti-corona ability of face field strength distribution, safe and reliable, the transformer station that it is adapted at compact conformation uses.This bus is made various geometries easily simultaneously, satisfies the needs of installation environment.
The technology solution that realizes another purpose of the present invention is: the outside that bus bar terminal connects the skeleton of protective device is provided with insulation equal gland tube, ground connection electric screen and overcoat successively, and the two ends of the equal gland tube that insulate are provided with and can make the flange that forms seal cavity in the sleeve.The equal gland tube of described insulation is to be twined by epoxy resin impregnated insulating paper to form insulating barrier, and the capacitor voltage equalizing screen of all pressing usefulness is set in insulating barrier at interval.Described skeleton is the metallic shield tube.The ground connection electric screen that bus bar terminal connects protective device is connected with the busbar grounding electric screen, forms equipotential.The skeleton that bus bar terminal connects protective device is connected with the bus terminal by feeler, forms equipotential and connects.The benefit of this connection is equal along the current potential everywhere of bus total length, and electric field is even.The bus of flange passes and is provided with sealing ring in the hole, and the reliable invasion and attack that guarantee not to be subjected in the equal gland tube of insulation moisture and rainwater make the bus bar terminal junction in the space of sealing, and are safe and reliable.
Characteristics of the present invention are: safe and reliable, the generation that can stop frequently to take place single-phase earthing and phase fault accident in service, even along the face field strength distribution, anti-corona ability is strong, applied widely, the transformer station that both had been fit to compact conformation uses, and can make various geometries again, satisfies the needs of installation environment.Cooperate bus bar terminal to connect the use of protective device, further improve its reliability, simultaneously can be according to the installation requirement bus that extends arbitrarily, it is convenient to install.Bus is connected protective device with bus bar terminal do not need casting mold in manufacture process, greatly reduce manufacturing cost.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of bus of the present invention;
Fig. 2 is the partial structurtes schematic diagram of another embodiment of the present invention;
Fig. 3 connects the structural representation of protective device for bus bar terminal of the present invention.
Embodiment
Be described further below in conjunction with accompanying drawing:
