Embodiment one
It please refers to Fig.1 and Fig. 2, the torque for being respectively the present embodiment tightly locks the explosive view of attachment device and the section view of ontology
Figure；Include ontology 1 and be set at least one hold-down bolt of ontology 1 as shown, the torque of the application tightly locks attachment device
2.Wherein ontology 1 includes first connecting portion 11 and second connecting portion 12, and first connecting portion 11 is used to connect the leading-out terminal of transformer
Son, second connecting portion 12 match electric lead for connecting.The first connecting portion 11 of the present embodiment includes round tube hole 111 and waist hole 112,
Waist hole 112 is located at the side of round tube hole 111.The second connecting portion 12 of the present embodiment includes that two compression screw holes 121 and one insert
String holes 122, two compression screw holes 121 and plug wire hole 122 intersect vertically.Correspondingly, the present embodiment include two hold-down bolts, two
A hold-down bolt 2 is correspondingly arranged in two compression screw holes 121 respectively.
More specifically, round tube hole 111 or waist hole 112 correspond to the outlet terminal for being sheathed on transformer, according to actual installation
Position, outlet terminal corresponding selection round tube hole 111 or waist hole 112 are docked, and outlet terminal can be moved to appropriate in waist hole 112
Position.
Further, when there was only one with electric lead, the plug wire hole of second connecting portion 12, distribution are inserted in electric lead
It after conducting wire is inserted into the plug wire hole 122 of second connecting portion 12, then is compressed by two hold-down bolts 2 and matches electric lead, pass through two
Hold-down bolt 2 compresses, and prevents from deviating from electric lead.Preferably, the inner wall of plug wire hole 122 be equipped with screw thread, to increase hole wall with
Frictional force with electric lead, connection are more firm.More specifically, the bolt head of two hold-down bolts 2 includes the first bolt head
21 and second bolt head 22, the first bolt head 21 is located at the lower end of the second bolt head 22, wherein the first bolt head 21 and the second spiral shell
The maximum weighted torque of the junction of bolt head 22 is 20~25Nm.When tightening two hold-down bolts 2, operating personnel turns
Two bolt heads 22 are held to prevent 2 excessive pressure close-fitting electric lead of hold-down bolt from damaging the crust with electric lead or even breaking conducting wire
When the continuous torque for turning bolt is more than 20~25Nm, the junction of the first bolt head 21 and the second bolt head 22 will be broken,
Operating personnel just can not turn hold-down bolt 2 by turning the second bolt head 22 again, to indicate that hold-down bolt 2 is realizing pressure
It will not also cause to break damage conducting wire while tight conducting wire.After second bolt head 22 is twisted into two parts disengaging, in subsequent maintenance, lead to
It crosses and turns the first bolt head 21 to turn hold-down bolt 2, or replace and use new hold-down bolt 2.Preferably, the first bolt
First 21 and second the junction of bolt head 22 be arranged with rubber ring 23, junction is reinforced by rubber ring 23, promotes junction
Stress.
