Abstract

The utility model discloses a 60 to 100 thousand voltage high-voltage oil transformer, which is a novel 60 to 100 thousand voltage high-voltage transformer with small size, light weight and capability of preventing oil leakage. A horizontal suspended structure is adopted. Two wire kits of the transformer are suspended in a casing in parallel; a voltage division shield plate and a baffle plate are arranged between the two wire kits; the interior of an insulating plug is provided with an oil chamber in which insulating oil is filled to divide the oil chamber into multiple layers. The upper cover plate is provided with an expansion and contraction chamber, which can prevent oil leakage, prevent polar substances from arraying and bridging in the medium and reduces the volume and the diameter of the insulating plug as possible. The weight of a 100 thousand voltage transformer is only thirty kilograms.

Description

60-100 thousand voltage high-tension oil transformer

The utility model relates to a kind of six--and 100,000 volts of high voltage oil immersion transformers are the components and parts on a kind of high-pressure electronic tester.

In existing technology, the oil immersion high-tension transformer generally all is that volume is big, Heavy Weight (what have reaches more than hundred kilograms), and conservator is arranged, and form opening structure, need the periodic replacement oil reservoir.Because the restriction of existing structure raises two die openings from widening with voltage, this is the very little main cause that it can not be done.Secondly, the High-Voltage Insulation bolt punctures in order to avoid, and that generally all does is very thick, if operating voltage surpasses 10,000 volts, the diameter of the bolt that insulate with regard to 80mm about.If 30,000 volts, also will carry out consolidation process.More increased weight.It is exactly that variation along with ambient temperature also oil leakage phenomenon can occur that existing oil-immersed type transformer also has a shortcoming, can adopt the method for conservator to solve in the oil-immersed type transformer of style of opening.And on electronic instrument, can't adopt conservator.So can't solve the phenomenon of leakage of oil.

The purpose of this utility model is at above-mentioned shortcoming, and it is little to design a kind of volume, can improve two interpolar voltage endurance capabilities, can prevent the new high voltage oil immersion transformer of leakage of oil.

Scheme of the present utility model is as follows: in order effectively to utilize physical dimension, make that structure is the compactest to be played the lie low suspention of formula of transformer with arm; Dividing potential drop barricades and cutoff board are installed in the middle of two line bags, and high pressure two is divided into two parts, and that it is difficult for is breakdown; In order to make the High-Voltage Insulation bolt avoid breakdown in the High-Voltage Insulation bolt, irritate oil and multilayer separation; Adopt totally enclosed structure, and increase flexible chamber at the top of transformer, when oil during in heat expansion, could be up to flexible indoor, in case leak-stopping oil.

The utility model novel structure has reached designing requirement fully, and overall volume is little, in light weight, High-Voltage Insulation bolt diameter is six--and also have only 55mm in the time of 100,000 volts, weight has only 30 kilograms.Both having made is under 100,000 volts the high pressure, owing to improve two interpolar withstand voltage propertiess, set dividing potential drop barricade and cutoff board can prevent effectively that polar substances from arranging bridging in medium and breakdown.Be provided with the grease chamber in the High-Voltage Insulation bolt and adopt irritate oil and hierarchy repeatedly, also capable of blocking in the oil reservoir polar substances arrange, put up a bridge and puncture, that just it goes without doing is very big for the bolt that insulate like this.Therefore it is little, in light weight, high pressure resistant to have reached volume, can reach and boost six--the purpose of 100,000 volts high pressure.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1--Fig. 5 is embodiment of the present utility model.Fig. 1 is 1 front view; Fig. 2 is a vertical view; Fig. 3 is that A-A is to cutaway view; Fig. 4 is an electrical schematic diagram.Fig. 5 is the installation diagram of dividing potential drop barricade and cutoff board.

Six--100,000 volts of high voltage oil immersion transformers two insulate bolt (1), (1-1), be fastened on by attachment screw (2) and fixture (5) on the upper cover plate (4) of transformer, in upper cover plate (4) and the housing (6) by four arms (12) by four bolts (17), (20) with in two parallel housings of hanging under upper cover plate (4) (6) of line bag.Make it form horizontal overhung construction.Be different from present straight hanging and sink to the bottom the formula structure.Compact conformation, size are minimum as much as possible.Be provided with dividing potential drop barricade (10) and cutoff board (15) between two line bags (8), (18) simultaneously.Dividing potential drop barricade (10) is made by the copper pool, and both sides are clamped the inserted fixed support (11) that is fixed on by epoxy resin board (9) and gone up (as shown in Figure 5).Fixed support is fixed between two plate washers (16).The diameter of two insulate bolt (1), (1-1) has only 55mm.In insulation bolt (1), (1-1), it is grease chamber (3) that a space is arranged, interior jar of insulating oil, and establish separate layer (19) multilayer and separate.Be provided with a flexible chamber (13) on the top of cover plate (4), logical by the oil phase in passage (14) and the housing (6), rise in the flexible chamber (13) when oil expands when ambient temperature raises, thereby can not produce oil leakage phenomenon.In Fig. 3, the iron core (17) of the cutoff board both sides of being seen is iron cores of line bag (8), and figure center line bag (8) is blocked by cutoff board (15).De1 shown in Fig. 2, de2, de3, de4, de5 connector lug respectively with schematic diagram de1 shown in Figure 4, de2, de3, de4, de5 correspondence.De1, de2 are two statures of first coil.De3 is a gage outfit; De4, de5 are two statures on time coil.Because the line bag is two 30KV(or 50KV), be 60KV(or 100KV so insulate between bolt (1), (1-1)).
