Abstract
The utility model discloses a clamp piece insulation structure with a fixed grounding wire. The clamp piece insulation structure comprises a web plate and pad blocks which are arranged on the web plate side by side. The pad blocks comprise a grounding pad block, right-angle groove opening pad blocks and middle pad blocks. The grounding pad block is placed on the outer side, one end of the grounding pad block extends out of the web plate, an iron core grounding hole is formed in the extending-out end, the right-angle groove opening pad blocks are evenly distributed below the web plate, and the middle pad blocks are arranged between two adjacent right-angle groove openings. During mounting, the problem that a supporting plate is welded on a clamp piece is avoided, other insulation pieces for fixing a grounding wire are of no need, the structure is simple, manufacturing is convenient, and cost is low.
Description
Technical field
The utility model belongs to transformer installation component, relates in particular to the clamp insulation structure of transformer box cover grounding sleeve.
Background technology
In high-power transformer, General Requirements has special grounding sleeve, far away apart from case lid from iron core earth connection out, if do not have fixingly, apart from the distance of live part, cannot guarantee, if weld support from folder, installs comparatively loaded down with trivial details.
Summary of the invention
Goal of the invention: in order to solve many shortcoming of prior art, the utility model provides a kind of clamp insulation structure with dead earth line, is convenient to iron core earth connection out and installs.
Summary of the invention: in order to reach foregoing invention object, the utility model is by the following technical solutions: a kind of clamp insulation structure with dead earth line, comprise web and be located at side by side the cushion block on web, described cushion block comprises ground connection cushion block, the middle cushion block of right angle notch cushion block, described ground connection cushion block is positioned at outside, web is stretched out in one end, and is provided with iron core grounding hole at this external part; Described right angle notch cushion block is evenly distributed under web; In the middle of described, cushion block is located between adjacent two right angle notches.
As preferably, described right angle notch cushion block is comprised of two filler strips, and single filler strip end is provided with step, and the step of two filler strips is established relatively.
As preferably, described right angle notch cushion block has 3.
Compared with prior art, the utlity model has following advantage: during installation, avoid welding support plate on folder, and other are for the insulating part of dead earth line; And simple in structure, easy to make, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
Wherein, web 1, ground connection cushion block 2, right angle notch cushion block 3, middle cushion block 4, iron core grounding hole 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated further; it may be noted that: embodiment is only for the content of the technical solutions of the utility model of explaining; do not limit protection range of the present utility model; on after reading comprehension technical solutions of the utility model; those skilled in the art are not departing under the prerequisite of the utility model principle; can also make further modification and retouching to said apparatus, these modifications and retouching are also considered as protection range of the present utility model.
As shown in Figure 1, a kind of clamp insulation structure with dead earth line, comprises web and cushion block, and concrete design and installation method is as follows:
Web (insulating board DY100/00) size determines according to the size of folder, general the same with folder size or smaller, and the hole on web is definite according to the position of other screw rod and thickness, and it is thick that web is generally 3mm.
Cushion block (laminated paper board DY100/00) has three kinds of specifications, and a kind of is the ground connection cushion block of ribbon core ground hole, and height determines according to fuel tank height etc., and one of quantity is located at outermost; With a right angle notch cushion block for right angle notch, height is the same with folder, the general 30 ~ 100mm of width, and notch is definite according to iron core shrouding size, and quantity is 3; Finally a kind of is not with holes and middle cushion block notch, and height is the same with folder, the general 30 ~ 50mm of width, and thickness is determined according to the distance of folder and iron core, and quantity is determined (distance between general warranty cushion block is at 30 ~ 50mm) according to the length of folder.
Cushion block is bonded on web by white glue with vinyl by above principle defined size.
Note: with the cushion block of ground hole, be placed on left side or the right side of clamp insulation, and be to be placed on high-pressure side, or low-pressure side, according to the position of grounding sleeve on case lid, determine.
Claims (3)
1. the clamp insulation structure with dead earth line, it is characterized in that: comprise web and be located at side by side the cushion block on web, described cushion block comprises ground connection cushion block, the middle cushion block of right angle notch cushion block, described ground connection cushion block is positioned at outside, web is stretched out in one end, and is provided with iron core grounding hole at this external part; Described right angle notch cushion block is evenly distributed under web; In the middle of described, cushion block is located between adjacent two right angle notches.
