Abstract
The utility model provides a dry-type transformer low pressure lead wire, including outer copper bar, interior copper bar and installing support, be equipped with the first insulator between outer copper bar and the interior copper bar of saying, be equipped with the second insulator between interior copper bar and the installing support of saying. The utility model discloses a dry-type transformer low pressure lead wire has following technological effect: 1) because an insulator is added, the insulating strength and the safety of the product are enhanced; 2) because the insulator is added at the position corresponding to the original insulator, the mechanical strength and firmness of the product are enhanced.
Description
Technical field
The utility model relates to a kind of dry-type transformer low-voltage lead, belongs to the transformer technology field.
Background technology
The dry-type transformer low-voltage lead is connected the in-out end of low-voltage coil, uses copper bar as lead-in wire usually, is fixed with an insulator usually between the existing copper bar lead-in wire.Such dry-type transformer low-voltage lead mainly exists following weak point: 1) dielectric strength is lower; 2) because two copper bars have an insulator between going between, and copper bar and mounting bracket are blank parts, the unbalanced situation of mechanical strength can occur.
Summary of the invention
The purpose of the utility model is the weak point that overcomes prior art, and a kind of dry-type transformer low-voltage lead is provided.
The dry-type transformer low-voltage lead of the utility model comprises outer copper line, inner copper line and mounting bracket, is provided with first insulator between said outer copper line and the inner copper line, is provided with second insulator between inner copper line and the mounting bracket.
Preferably,
Said second insulator and first insulator are on the same horizontal level.
The dry-type transformer low-voltage lead of the utility model has following technique effect:
1) owing to increased an insulator, product dielectric strength and fail safe have obtained enhancing; 2) owing on the corresponding position of original insulator, increased an insulator, product
Mechanical strength and fastness have obtained enhancing.
Description of drawings
Fig. 1 is the structural representation of the dry-type transformer low-voltage lead of the utility model.
Wherein, 1 is outer copper line, and 2 is inner copper line, and 3 is mounting bracket, and 4 is first insulator, and 5 is second insulator, and 6 is low-voltage coil.
Embodiment
Come the utility model is done to specify further below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1; The dry-type transformer low-voltage lead of the utility model is fixed on the low-voltage coil 6; Comprise outer copper line 1, inner copper line 2 and mounting bracket 3, be provided with first insulator 4 between outer copper line 1 and the inner copper line 2, be provided with second insulator 5 between inner copper line 2 and the mounting bracket 3.Second insulator 5 and first insulator 4 are on the same horizontal level.
Claims (2)
1. the dry-type transformer low-voltage lead comprises outer copper line, inner copper line and mounting bracket, it is characterized in that, is provided with first insulator between said outer copper line and the inner copper line, is provided with second insulator between said inner copper line and the mounting bracket.
