It is in flap to state conductive part, and uniform along the circumferencial direction of the conducting rod main body section, the conducting rod main body periphery ring portion
And between two conductive parts of arbitrary neighborhood be insulation division, each conductive part in the conducting rod main body and each return
End conductor connects one to one.
The conductive part section is in fan-shaped flap.
The conductive part is made up of section in fan-shaped aluminium bar.
The insulation division is silicon rubber.
The advantages of the utility model is with good effect：
1st, the utility model using silicon rubber cast makes insulated part and current-carrying part is combined into one structure, is effectively ensured
Insulation effect.
2nd, the utility model conducting rod main body section is in more valve structures, improves conductive rod area, Jin Erti to greatest extent
The resistance to short circuit current ability of high current transformer.
Brief description of the drawings
Fig. 1 is end view of the present utility model,
Fig. 2 is use state diagram of the present utility model.
Wherein, 1 is conductive part, and 2 be insulation division, and 3 be oil conservater, and 4 be return conductor.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, the utility model includes conducting rod main body and screening conductive pipe, and the conducting rod main body places
In oil conservater 3, screening conductive pipe is cased with the outside of conducting rod main body and is isolated with the oil medium in oil conservater 3, the conducting rod
Main body section is in more valve structures, and rounded on the outside of each valve, mutual so as to improve electric current to improve conductive rod area to greatest extent
The resistance to short circuit current ability of sensor.
As shown in figure 1, the conducting rod main body is cylindrical and including insulation division 2 and multiple conductive parts 1, led along described
The axial direction of electric pole main body is looked, and the conductive part 1 is in fan-shaped flap, and uniform along the circumferencial direction of conducting rod main body section,
It is insulation division 2 between the conducting rod main body periphery ring portion and two conductive parts 1 of arbitrary neighborhood, in the present embodiment, institute
State conductive part 1 to be made up in fan-shaped aluminium bar of section, the insulation division 2 is that silicon rubber cast forms, and utilizes respective mode during production
Tool, which completes cast, makes the insulation division 2 and each conductive part 1 be combined into one structure.
As shown in Fig. 2 the end of the conducting rod main body is connected with multiple ends of return conductor 4 on oil conservater 3, and institute
The each conductive part 1 stated in conducting rod main body connects one to one with each return conductor 4 end, and insulation division 2 plays absolutely
Edge acts on, and because silicon rubber has an excellent heat endurance and resistant of high or low temperature, insulation division 2 of the present utility model can-
Long-term work under 60 DEG C~+250 DEG C states, anti-corona, electric arc, electric spark are very competent, weather-resistant and radiation, gas permeability
It is good, insulation effect is effectively ensured.
Operation principle of the present utility model is：
The utility model insulation division 2 and each conductive part 1 are combined into one structure, and the insulation division 2 pours for silicon rubber
Note forms, and has excellent heat endurance and resistant of high or low temperature, insulation effect is effectively ensured, and conducting rod main body section is in more in addition
Valve structure, conductive rod area is improved to greatest extent, and then improve the resistance to short circuit current ability of current transformer.
