Description

Body fixed structure of combined insulated dry current transformer

Technical field

The utility model relates to current transformer field, specifically a kind of combined insulated dry current transformer is primary Body fixed structure.

Background technique

As shown in figure 3, in the prior art, U-typed body of combined insulated dry current transformer is stood in cabinet, device Body bottom end is placed in a upside on the body seat of cambered surface, and body center bottom is fixed with a fixed plate, user in use, P1 terminal is coupled with conducting wire respectively with P2 terminal, thus make P1 terminal with P2 terminal respectively by phase outside pulling force F1 And F2, it is generally the case that the conductor length on both sides is different, or is conducting wire connection on one side, is that pipe mother connects on one side, this The pulling force F2 that the pulling force F1 and P2 terminal that sample P1 terminal is subject to is subject to is different, it is easy to cause a body big to pulling force A side inclination because fixing fixation plate thickness usually only 1.0mm used in a body bottom end, stress is limited, electric current At runtime, if it find that there is body inclination conditions, just necessary horse back power failure processing, certain warp is caused to substation to mutual inductor Ji loss.

In addition as shown in figure 4, in the prior art, set on cabinet there are two watt seat, a U-typed body it is vertical it is good after, Two ends of open side are each passed through corresponding watt of seat, and are fixed with certain thickness tile, are then withstood with bolt Tile, but certain alignment watt seat center can not be completely secured since tile thickness cannot change, when erecting a body, There can be certain deviation, allow for that the position that body has is too tight, and some positions are too loose in this way, exert oneself unevenness to a body It is even, it is easy to make a body to generate screen sliding phenomenon in this way, and watt have certain gap between seat and tile, rainwater is also easy to Entered in cabinet by gap.

Utility model content

The purpose of this utility model is to provide a kind of body fixed structure of combined insulated dry current transformer, The bottom of box is equipped with fixed casting portion and a body is auxiliarily fixed, while being equipped with connection pouring layer in watt seat and realizing a body Connection between end and watt seat guarantees that a body is fixed and uniform force, while guaranteeing that rainwater may not flow into cabinet It is interior.

The purpose of this utility model is achieved through the following technical solutions:

A kind of body fixed structure of combined insulated dry current transformer, including a body and cabinet, a device Body is set in cabinet, is equipped with body seat in the bottom of box, a body bottom end is placed on the body seat and passes through one admittedly Fixed board is fixed on the bottom of box, is equipped with fixed casting portion in the bottom of box, and the body seat and fixed plate are all set in It in the fixed casting portion, is set on the upside of the box roof there are two watt seat, and two ends difference on the upside of a body Across corresponding watt of seat, connection pouring layer is equipped between a body upper side end and corresponding watt of seat.

Body seat upper surface is in cambered surface, and one time body bottom end is placed in the cambered surface.

Two ends of side opening are connected after being each passed through corresponding watt of seat with corresponding terminal post on body.

The fixed casting portion forms for poured with epoxy resin.

The connection pouring layer forms for poured with epoxy resin.

The cabinet includes upper box and lower box, and the lower box internal diameter is less than upper box, in the lower box upper end Outside is equipped with pivot flange, and the tank wall lower end of the upper box is bolted on the pivot flange outer end, fixed casting Portion is set to lower box bottom.

The advantages of the utility model and good effect are as follows:

1, the utility model is equipped with fixed casting portion in the bottom of box and a body is auxiliarily fixed, even if P1 terminal and the end P2 Sub- under tension has a certain difference, body will not run-off the straight, while also increasing cabinet base intensity.

2, the utility model casting epoxy resin in watt seat forms connection pouring layer and fixes a body end, both guarantees Body end uniform force, and there is no gaps, and rainwater to be allowed to flow into cabinet between watt seat and a body end, Tile structure is also eliminated simultaneously, reduces processing cost.

Wherein, 1 is a body, and 2 be cabinet, and 201 be upper box, and 202 be lower box, and 203 be pivot flange, and 3 be solid Fixed board, 4 be body seat, and 5 be tile, and 6 be bolt, and 7 be watt seat, and 8 be fixed casting portion, and 9 be connection pouring layer.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Fig. 1~2, the utility model includes a body 1 and cabinet 2, and one time body 1 is set in cabinet 2, 2 bottom of cabinet is equipped with the body seat 4 that upper surface is in cambered surface, and one time 1 bottom end of body is placed in the cambered surface of the body seat 4, and institute It states 1 center bottom of body to be fixed on the bottom plate of the cabinet 2 by a fixed plate 3, be equipped in 2 bottom of cabinet Fixed casting portion 8, and the body seat 4 and fixed plate 3 are all set in the fixed casting portion 8, are divided on the upside of the cabinet 2 Not She You P1 terminal post and P2 terminal post, on a body 1 two ends of side opening pass through 2 top plate of cabinet and point It is not connected with P1 terminal post and P2 terminal post, is set on the upside of 2 top plate of cabinet there are two watt seat 7, and as shown in Fig. 2, described Two ends of 1 upside of body are connected after being each passed through corresponding watt of seat 7 with corresponding terminal column, 1 upside of body Connection pouring layer 9 is equipped between end and corresponding watt of seat 7.In the present embodiment, the fixed casting portion 8 and connection pouring layer 9 are equal It is formed for cooled and solidified after casting epoxy resin.

As shown in Figure 1, the cabinet 2 of the utility model is in inverted convex, the cabinet 2 includes upper box 201 and nowel Body 202, and 202 internal diameter of the lower box is less than upper box 201, and pivot flange is equipped on the outside of 202 upper end of lower box 203, the tank wall lower end of the upper box 201 is bolted on 203 outer end of pivot flange, and fixed casting portion 8 is poured In lower box 202, guarantee 2 barycentre steadiness of cabinet, so that the support of cabinet 2 is more firm, the dismounting of cabinet 2 is also very convenient, convenient Poured with epoxy resin in lower box 202 forms fixed casting portion 8 and a body 1 is stood up, and can also reduce epoxy resin and pour Fluence reduces cost.

The working principle of the utility model are as follows:

As shown in figure 3,1 bottom of a body in the prior art is usually only fixed by a fixed plate 3, when P1 terminal With P2 terminal when the pulling force F1 and F2 of different sizes by two sides, one time body 1 is easy to happen inclination, in addition as shown in figure 4, one Tile 5 is typically provided between secondary 1 upper side end of body and watt seat 7, the tile 5 is fixed in watt seat 7 by bolt 6, is erected Certain alignment 7 center of watt seat can not be completely secured when body 1, there can be certain deviation, so that a body 1 Unbalance stress is easy to produce screen sliding phenomenon, and has certain gap between watt seat 7 and tile 5, and rainwater is also easy to pass through seam Gap enters in cabinet.

As shown in Figure 1, the utility model is using traditional fixed plate 3 and 4 structure of body seat simultaneously, to 2 bottom of cabinet It is poured a certain amount of epoxy resin and forms fixed casting portion 8 for a body 1 to be auxiliarily fixed, accordingly even when P1 terminal and the end P2 Even if sub- under tension has a certain difference, body 1 will not run-off the straight, while also increasing 2 pedestal intensity of cabinet.Separately Outside as shown in Fig. 2, the utility model casting epoxy resin in watt seat 7, which forms connection pouring layer 9, fixes 1 end of body, Both 1 end uniform force of a body had been guaranteed, and has allowed rainwater stream there is no gap between watt seat 7 and 1 end of body Enter in cabinet 2, while also eliminating 5 structure of tile.
