Abstract
The present invention relates to a kind of method for carrying out cable connecting terminal detection using flaw detection compensation block, the binding post includes left side tabletting end and right side threading end, and the method comprising the steps of has：(1) make and agree with completely with right side threading end left end face and height identical same material compensation block on the top at tabletting end；(2) using the vertical transillumination of X-ray, scanning thickness T=tablettings end thickness T1+ compensation block T2 select tube voltage, tube current, time for exposure and focal length to carry out x-ray inspection shooting further according to used X-ray machine X.The problem of cable connecting terminal of the present invention can not be Polaroid when solving radiographic inspection applied on binding post with radiographic inspection compensation block, has opened up application of the radiographic inspection in field of power transmission, the safety of transmission line of electricity has been ensured significantly.
Description
Technical field
The invention belongs to power system technical field of power generation and power equipment manufacture system of processing technical field, particularly one
Plant the method for carrying out cable connecting terminal detection using flaw detection compensation block.
Background technology
Crimp type binding post is generally used during the in-service transmission line of electricity wiring of power system, in recent years, due to binding post
Crimped when quality problems itself is with crimping it is improper caused by electric power accident attract attention.In order to ensure gold utensil in itself
Quality and compression joint technique quality, it is to avoid underbead crack or overvoltage occur, under-voltage, can use X-ray to be detected, such as Fig. 1 institutes
Show, binding post includes the tabletting end 1 in left side and the threading end 3 on right side, and due to binding post tabletting end itself and threading end
Intersecting root shape and thickness difference, can cause image blackness on egative film to differ greatly, it is impossible to realize Polaroid.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, and to propose a kind of to carry out cable connection using flaw detection compensation block
The method of terminal test.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of method for carrying out cable connecting terminal detection using flaw detection compensation block, the binding post includes left side tabletting
End and right side threading end, are formed with two bolts hole in left and right, it is as follows that the method comprising the steps of on the tabletting end of left side：
(1) according to the right side threading end of binding post left side tabletting end top shape and thickness difference, at tabletting end
Top is made agrees with and height identical same material compensation block completely with right side threading end left end face；
(2) using the vertical transillumination of X-ray, scanning thickness T=tablettings end thickness T1+ compensation block T2 are penetrated further according to using
Line machine selection tube voltage, tube current, time for exposure and focal length carry out x-ray inspection shooting.
Moreover, the length of the compensation block is to extend to the left and right two to the left by the interface at tabletting end and threading end
The middle part of bolt hole.
Advantages and positive effects of the present invention are：
1st, when cable connecting terminal of the present invention solves radiographic inspection applied on binding post with radiographic inspection compensation block
Can not be Polaroid the problem of, application of the radiographic inspection in field of power transmission is opened up.
2nd, the present invention is suitable for the radiographic inspection compensation block of in-service power line cables binding post, and transmission of electricity has been ensured significantly
The safety of circuit.
Brief description of the drawings
Fig. 1 is the structural representation of middle connecting terminal of the present invention；
Fig. 2 is that compensation block is placed on the structural representation on binding post in the present invention；
Fig. 3 is Fig. 2 top view.
Embodiment
The embodiment of the present invention is further described below：It is emphasized that embodiment of the present invention is explanation
Property, rather than it is limited, therefore the present invention is not limited to the embodiment described in embodiment, it is every by this area
The other embodiment that technical staff's technique according to the invention scheme is drawn, also belongs to the scope of protection of the invention.
A kind of method for carrying out cable connecting terminal detection using flaw detection compensation block, it is as follows that the method comprising the steps of：
(1) shape of the right side threading end 3 of binding post of the basis as shown in Fig. 1 or 2 or 3 on the top of left side tabletting end 1
And thickness difference, make and agree with completely with right side threading end left end face and the compensation of height identical same material on the top at tabletting end
Block 3.
(2) using the vertical transillumination of X-ray, scanning thickness T=tablettings end thickness T1+ compensation block T2 are penetrated further according to using
Line machine selection tube voltage, tube current, time for exposure and focal length carry out x-ray inspection shooting, take egative film after darkroom disposal
It can be observed by viewbox, discover whether there is binding post underbead crack or overvoltage, under-voltage phenomenon.
In the specific implementation of the present invention, two bolts hole in left and right, institute are being formed with the left of the binding post on tabletting end
The length for stating compensation block is to extend to the middle part of two bolts hole in the left and right to the left by the interface at tabletting end and threading end, this
Sample, in x-ray inspection shooting process, the bolt hole below compensation block can form shade, and the border of the shade can be for
Than the feature of pair of wire connection terminals underbead crack.
Claims (2)
1. a kind of method for carrying out cable connecting terminal detection using flaw detection compensation block, the binding post includes left side tabletting end
