Description
Technical field
The utility model relates to a kind of use for electric locomotive DC capacitor formula sleeve pipe, belongs to electric locomotive accessory structure design field.
Background technology
In existing sleeve pipe, insulating sleeve coheres in capacitance core external body by glue, and insulating sleeve is provided with and passes for end shield lead-in wire the perforation be connected with mounting flange.Adopt the deficiency that said structure exists: insulating sleeve and capacitance core body interface easily produce bubble, through gas channel can be formed after numerous bubble is connected, partial discharge phenomenon is formed under voltage effect, product is in During Process of Long-term Operation, partial discharge makes interfacial insulator performance reduce, and insulating sleeve will lose insulating effect; In addition, sternly just have steam does not enter interiors of products by hole of boring a hole to the aperture seal on insulating sleeve, and so the quality of product just cannot ensure.
Utility model content
To this, the purpose of this utility model is to provide a kind of rational in infrastructure, the use for electric locomotive DC capacitor formula sleeve pipe of reliable in quality.
The technical scheme realizing the utility model object is:
A kind of use for electric locomotive DC capacitor formula sleeve pipe, comprises sleeve body and mounting flange, and described sleeve body comprises the electric capacity core body be made up of current－carrying conductor and the capacitance plate being located at described current－carrying conductor outside and the insulating sleeve being located at described capacitance core external body; Described mounting flange and described capacitance plate are gone between by end shield and are connected; Described mounting flange is set in described capacitance core external body, described end shield lead-in wire is weldingly connected with the inwall of described mounting flange, described insulating sleeve sulfuration is formed on the external wall of described capacitance core, and covers described end shield lead-in wire and the gap between described mounting flange and described electric capacity core body.
In technique scheme, described insulating sleeve outer wall forms full skirt.
In technique scheme, described sleeve body two ends are provided with fixture, described fixture comprises clamping plate, folder lid and is connected described clamping plate and describedly presss from both sides the fastening bolt covered, be provided with the clamping hole clamping described current－carrying conductor between described clamping plate and described folder lid, the connecting hole connecting external cord takes shape on described clamping plate.
In technique scheme, in described clamping hole, be provided with double wedge.
In technique scheme, described mounting flange is provided with seal groove, is provided with sealing ring in described seal groove.
The utility model has positive effect: the described insulating sleeve in the utility model is formed on the external wall of capacitance core by high temperature injection sulfuration, insulating sleeve and electric capacity core body can be made like this to combine together, avoid occurring gap between the two, avoid the situation that the inefficacy of described insulating sleeve occurs; Meanwhile, end shield lead-in wire is connected with the inwall of mounting flange, and insulating sleeve also covers end shield lead-in wire and the gap between mounting flange and electric capacity core body, so, without the need to arranging perforation on insulating sleeve, effectively preventing steam from entering interiors of products, ensure that product quality.
