Abstract
The utility model provides a 500 KV lead-out device for a transformer. The 500 KV lead-out device for the transformer is characterized by comprising a stainless steel shielding tube, wherein insulation paper is wrapped outside the stainless steel shielding tube; one port of the stainless steel shielding tube extends into the angle ring of a coil, and the other port extends into a shield ring system; and an angle ring system is arranged on the shield ring system and used for dividing an oil clearance on the surface of the shield ring system. The lead-out device solves the head-end lead-out problem of 500 KV the transformer, has a simple structure, and is convenient in installation and low in cost.
Description
Technical field
The utility model relates to a kind of 500 kilovolts of outgoing line devices, is used for 500 kv transformer high pressure head end outlets.
Background technology
The power transformer of present domestic highest voltage level is 1000kV, but only has tentative circuit seldom, and product is that large factory of domestic a few family and overseas-funded enterprise are carved up.The ceiling voltage system of operation is 500kV in addition, and the manufacturer that at present product by State Grid Corporation of China's audit can hanging net operation has about 15, and the designing technique production technology of its 500kV transformer all is secret for each producer.The 500kV outlet of its high pressure head end is the key of production for the 500kV transformer, the outlet insulation level of head end is the highest, and near the grounding electrode it is complex-shaped, causes Electric Field Distribution complicated, processes careless slightlyly will discharge or produce partial discharge.
Summary of the invention
The purpose of this utility model provides a kind of outgoing line device of the 500kV of solution transformer head end outlet problem.
In order to achieve the above object, the technical solution of the utility model has provided a kind of transformer with 500 kilovolts of outgoing line devices, it is characterized in that: comprise stainless steel shielding pipe, be wrapped with insulating paper at stainless steel shielding pipe, a port of stainless steel shielding pipe stretches in the square ring of coil, its another port stretches in the shading ring system, is provided with to cut apart the square ring system of shading ring system surfaces oil clearance in the shading ring system.
Preferably, the outer insulating paper of a port that is wrapped in described stainless steel shielding pipe is wrapped up tapered.
Preferably, described shading ring system comprises the two-layer shading ring of vertical placement, is wrapped with insulating barrier at every layer of shading ring.
Preferably, the system of square ring shown in comprises at least 3 formable layer square rings of stacked on top of one another.
Preferably, the external diameter of described stainless steel shielding pipe is 100mm.
Preferably, described another port is tapered.
The utility model provides a kind of outgoing line device of the 500kV of solution transformer head end outlet problem, and this apparatus structure is simple, and is easy for installation, and with low cost.
Description of drawings
A kind of transformer that Fig. 1 provides for the utility model is with 500 kilovolts of outgoing line devices.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
In conjunction with Fig. 1, the utility model provides a kind of transformer with 500 kilovolts of outgoing line devices, comprises that external diameter is the stainless steel shielding pipe 1 of 100mm, is wrapped with insulating paper 2 at stainless steel shielding pipe 1.A port A of stainless steel shielding pipe 1 stretches in the square ring of coil, and is tapered in insulating paper 2 wrappings of this port A outer wrapping.Another port B of stainless steel shielding pipe 1 extend in the shading ring system 3, and B is tapered for this port.In the present embodiment, shading ring system 3 comprises the two-layer shading ring of vertical placement, is wrapped with insulating barrier at every layer of shading ring.Stainless steel shielding pipe 1 connects extremely by a lead-in wire with transformer coil outlet with shading ring system 3, guarantees that current potential is identical and guarantees not current-carrying of shielded-plate tube.Be provided with square ring system 4 in shading ring system 3.Square ring system 4 comprises 5 formable layer square rings of stacked on top of one another.The effect of square ring system 4 is oil clearances of cutting apart shading ring system 3 surfaces, improves the tolerance field intensity of oil clearance.
