Abstract
The utility model discloses a composite insulating tube-shaped bus, which relates to a composite insulating tube-shaped bus used for an electric power system. The composite insulating tube-shaped bus is designed in order to resolve the contact problems between the terminal fitting of the composite insulating tube-shaped bus currently sold in the market and the contact surface of the draft tube of the tube-shaped bus, such as low contact pressure, high contact resistance, high temperature rise and high cost. The composite insulating tube-shaped bus comprises a composite insulating tube-shaped bus draft tube and a composite insulator; wherein, the terminal of the draft tube is tabular; and the draft tube is provided with a venthole. The composite insulating tube-shaped bus, which has the advantages of simple structure and low cost, can be directly connected with other terminals and does not need a plug-in terminal fitting or an external hooping terminal fitting, thus reducing the transitional link in connection, the temperature rise at the joint of the bus terminal is low, and thereby, the safety coefficient of the operation of the composite insulating tube-shaped bus can be greatly increased.
Description
Technical field
The utility model relates to a kind of electric power system 6-35kV electric pressure compound inslation tubular bus.
Background technology
At present, the compound inslation tubular bus terminal of selling on the market mainly contains two kinds of connected modes for circular during construction, a kind of employing interpolation method, and its shortcoming is that mounting process complexity, interpolation junction resistance are big, terminal fitting weight is heavier; Another mode is to adopt outer anchor ear mode, and its shortcoming is that terminal fitting takies than large space, and junction resistance is bigger, and terminal fitting weight is greater than first kind of mode; The mozzle contact-making surface contact pressure of above dual mode terminal fitting and tubular bus is little, and contact resistance is big, and temperature rise is higher, the cost height.
Summary of the invention
It is little that the technical problems to be solved in the utility model provides a kind of junction resistance, the compound inslation tubular bus that operating safety factor is high.
Above-mentioned purpose is achieved in that existing compound inslation tubular bus comprises mozzle and compound inslation, we are pressed into the terminal of mozzle tabular by circle, terminal fitting as the compound inslation tubular bus, on mozzle, be processed with air vent hole, tabular terminal fitting can be processed into different size respectively according to the electric current difference, to guarantee the needs of ampacity.
The utility model has the advantages that simple in structurely, cost is low, can directly be connected with other terminal, can save interpolation terminal fitting or outer anchor ear terminal fitting, thereby reducing the transitional link that connects, the temperature rise of bus bar terminal junction is low, can greatly improve the coefficient of safety of compound inslation tubular bus operation.
Description of drawings
Fig. 1 is that master of the present utility model looks cross-sectional view.
Fig. 2 is a plan structure schematic diagram of the present utility model.
Embodiment
With reference to accompanying drawing 1,2, existing compound inslation tubular bus comprises mozzle 2 (copper pipe or aluminum pipe), compound inslation 1 is arranged on the mozzle, the terminal fitting 3 of mozzle is pressed into tabular, in the pressing process, pressure needs enough greatly, so that two metallic plate compactings of tabular terminal fitting, be processed with air vent hole 4 on mozzle, tabular terminal fitting can be processed into different size respectively according to the electric current difference, to guarantee the needs of ampacity.
Claims (1)
1. the compound inslation tubular bus comprises compound inslation (1), mozzle (2), and the terminal fitting (3) that it is characterized in that mozzle has air vent hole (4) for tabular on mozzle (2).
