Abstract

The utility model provides a convenient wiring transformer aiming at solving the defects that wiring terminals interfere with each other during the tapping and wiring structures are inconvenient to switch during the use when explosion-proof dry type transformers are produced. The convenient wiring transformer casing comprises a transformer casing with a low-voltage output end cover and is formed by fixing a tapping box with wiring terminals on the low-voltage output end cover of the transformer casing.

Description

Make things convenient for the wiring transformer shell

Technical field

The utility model discloses a kind of wiring transformer shell that makes things convenient for, belong to equipment for power transmission and distribution manufacturing technology field, is that a kind of shell that is used for flameproof dry type transformer, flameproof mining mobile transformer substation uses concretely.

Background technology

Flameproof dry type transformer is the visual plant that electrical source of power is provided for mining industry.Known flameproof dry type transformer includes transformer case, is provided with end cap on transformer case, is fixed with the binding post that high pressure and low pressure wiring are used on the transformer housing in the end cap; At the transformer case internal fixation transformation coil is arranged, the lead of coil be fixed on transformer case on, binding post in the end cap is electrically connected; Especially be connected with the outlet of binding post at low-voltage side coil, generally be directly to draw a, b, c, x, y, z totally 6 junction blocks, 1 temperature signal controller junction block and the chain control junction block of high-low pressure from the low pressure wire cavity, totally 8 junction blocks, this existing flameproof dry type transformer has following defective in actual applications: this is because the structure space of transformer case low pressure side is limited, draw the control of 6 junction blocks and 1 temperature signal, the chain control junction block of high-low pressure simultaneously, the position is difficult to arrange; The soft copper row of transformer end cap inside, conducting rod connect and the interior lead-out wire of wire cavity, and are fixed on binding post interference mutually between tap of transformer case, exist potential safety hazard; Simultaneously, the low pressure Y-connection need be switched when connecting into triangle, flameproof dry type transformer then needs the low pressure wire cavity of dismantling, and installs the low pressure wire cavity again after having switched tap; Flameproof mining mobile transformer substation need be dismantled low tension switch lid, installs switch cover again after having switched tap, and every under mine, operating condition is limited, switches that tap extremely bothers and difficult, influences mine safety production.

Summary of the invention

At flameproof dry-type transformer producing the time binding post between tap, interfere mutually, use in the defective of wiring construction inconvenience when switching, the utility model provides a kind of wiring transformer shell that makes things convenient for, thisly make things convenient for the phase mutually noninterfere between tap of wiring transformer shell binding post in the mill, use in wiring construction do not need when switching the to dismantle low pressure wire cavity of transformer, easy to operate.

Taked following technical scheme for realizing the purpose of this utility model:

Make a kind of wiring transformer shell that makes things convenient for, this transformer case that makes things convenient for the wiring transformer shell to comprise to contain the low-voltage output lid, the described wiring transformer shell that makes things convenient for is to cover at the transformer case low-voltage output to be fixed with the breakout box that contains binding post.

Characteristics of the present utility model are simple in structure, easy to manufacture, easy to use; Its remarkable advantage is convenient when wiring construction is switched in binding post phase mutually noninterfere between tap when producing, the use, reduces the trouble of dismounting end cap.

Description of drawings

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:

The broken section structural representation of Fig. 1, an embodiment of the utility model;

The side-looking of Fig. 2, embodiment Fig. 1, broken section structural representation.

Among the figure: 1, end cap 2, tap box body 3, bolt 4, cover plate 5, binding post

Embodiment

As shown in Figure 1 and Figure 2,1 among the figure is the end cap that makes things convenient for wiring transformer shell low-voltage output, is fixed with tap box body 2 on end cap 1, is fixed with cover plate 4 by bolt 3 on tap box body 2, makes breakout box; At the breakout box internal fixation binding post 5 is arranged, binding post 5 is electrically connected with the lead of transformer case interior loop.

Because the utility model is fixed with breakout box on the end cap 1 of transformer case low-voltage output, the binding post 5 of breakout box internal fixation can be connected with the coil in the transformer case, therefore, thisly make things convenient for the binding post phase mutually noninterfere between tap in the mill of wiring transformer shell, use in wiring construction do not need when switching the to dismantle low pressure wire cavity of transformer, easy to operate.

This structure also is adapted to make flame-proof type mobile substation, ore deposit.

Claims

1. one kind makes things convenient for the wiring transformer shell, this transformer case that makes things convenient for the wiring transformer shell to comprise to contain low-voltage output lid (1) is characterized in that: the described wiring transformer shell that makes things convenient for is to be fixed with the breakout box that contains binding post (5) on transformer case low-voltage output lid (1).
