Fig. 2 is the structural schematic diagram of embodiment two；

Fig. 3 is the partial enlarged view in Fig. 2；

Fig. 4 is the exploded view of porcelain insulator in embodiment three.

In figure, 1 copper bar, 2 go out head, and 31 through-holes, 32 bands, 41 bolts hole, 42 cushion blocks, 43 fixing bolts, 44 second is logical Hole, 51 copper inserts, 52 porcelain elements, 53 full skirts, 54 grooves.

Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples：

Referring to figures 1-4.

Embodiment one：Present embodiment discloses a kind of novel foil low-voltage coil lead copper bar fixed structures, including two Copper bar 1 is equipped with the clamping machine for clamping two copper bars 1 between the top of described two copper bars 1 and the head 2 out of lower section The head 2 that goes out of structure, 1 upper and lower of copper bar simultaneously clamps on fixation by clamping device, keeps low-voltage coil coiling more compact, copper bar ruler The small not deviation of very little deviation.

The clamping device includes through-hole 31, the band 32 that two 1 upper and lowers of copper bar are arranged in and go out on head 2, the bundle With 32 one end sequentially pass through two copper bars 1 go out head 2 through-hole 31 after two ends be fixedly connected, the present embodiment pass through band 32 One end sequentially pass through two go out head 2 on through-hole 31 after, the head and the tail of band 32 are connected and fixed, structure is simple, and cost is just Preferably, easy to operate, keep low-voltage coil coiling more compact, the small not deviation of copper bar dimensional discrepancy.

The aperture of the through-hole 31 is 10mm, is gripped convenient for band 32.

Embodiment two：The present embodiment is repeated no more with same section in embodiment one, the difference is that, the clamping machine Structure includes that two 1 upper and lowers of copper bar are arranged in go out the bolt hole 41 on head 2, go out the cushion block 42 and fixed spiral shell between head 2 Bolt 43, the cushion block 42 are equipped with the second through-hole 44 passed through for fixing bolt 43, and the present embodiment passes through between head 2 out Cushion block 42 is placed, the second through-hole that setting is passed through for fixing bolt 43 on cushion block 42, such 1 top and the bottom of copper bar press from both sides simultaneously It fastens, keeps coil winding more compact, the small not deviation of 1 dimensional discrepancy of copper bar.

Preferably, second through-hole 44 and the bolt hole 41 are coaxial；The hole of second through-hole 44 and bolt hole 41 Diameter is equal with the outer diameter of the fixing bolt 43, it is ensured that after fixing bolt 43 can sequentially pass through bolt hole 41, the second through-hole 44 Copper bar 1 is gripped, and will not be of different sizes because of aperture and the outer diameter of fixing bolt 43, and causes fixing bolt 43 can be subjected to displacement radially, influence using effect；Cushion block 42 is preferably laminated wooden unit in the present embodiment, can be very good absolutely Edge.

The fixing bolt 43 is bakelite bolt, further strengthens the insulation between copper bar 1, avoids the work for influencing transformer Make.

Embodiment three：The present embodiment is repeated no more with two same section of embodiment, the difference is that：The cushion block 42 is Porcelain insulator, the porcelain insulator include two copper inserts 51, porcelain element 52, and the porcelain element 52 is solid porcelain body, the porcelain Full skirt 53 is equipped with outside element 52；52 both ends of porcelain element are equipped with groove 54, and described two copper inserts 51 are fixed on described recessed On slot 54, two copper inserts 51 are embedded on the both ends groove 54 of porcelain element 52 as adhesive by using cement and are constituted 2kv porcelain insulator effectively increases the creepage distance of porcelain insulator, improves structural strength.

52 surface of porcelain element is equipped with buffer layer, and the buffer layer is applied to the outside of porcelain element 52, to eliminate product The harmful stress because caused by longterm expansion coefficient is different under field conditions (factors).

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technical field, It is also included in the patent protection scope of the utility model.
