The utility model is illustrated with the compensation tuned cell product structure being directed in electrical equipment, but not
It is practical new to may be applicable to this for other track electrical equipments for the compensation tuned cell being only limited in track electrical equipment
Type.
As shown in Figure 1, compensation tuned cell product in the prior art includes box body 1 and lead wire cable 2, compensation tuning
Electric part in unit product is located at the inside of box body 1.When the prior art is to compensation tuned cell product test, only test is drawn
Connection cable 2 is located at the end outside box body 1, due to the deformation of lead wire cable 2, will cause the error of measurement result, and work as
When compensation tuned cell product breaks down, it is difficult to determine fault location.
As shown in Fig. 2, opening up test point mounting hole 5 to it, and in test point mounting hole 5 in 1 thermosetting of box body processing
It is put into built-in fitting 3.
As shown in figure 3, built-in fitting 3 is made from multiple components, it is fixedly connected between plurality of component, on built-in fitting 3
Internal electricity connection end 31 is connect with the electrical component in box body 1, and exposed electrical connecting pin 37 is then located at the outside of box body 1, is supplied
Test equipment is attached thereto.
The floor map of built-in fitting 3 as shown in Figure 4, the first clamping portion 33 and the second clamping portion 35 are gear-like,
The contact area of built-in fitting 3 Yu box body 1 is significantly increased, the reliability that built-in fitting 3 is contacted with box body 1 is ensure that, prevents pre-
It is relatively moved between embedded part 3 and box body 1.
Further, built-in fitting 3 is copper product, and copper product is to use fine copper or copper alloy for made of main Raw material processing
Daily necessity, the general designation of industrial goods.Subtracted using the characteristic of its excellent conductive of copper product when the electric current of test equipment passes through
Error when test is lacked.
As shown in figure 5, the installation of built-in fitting 3 and box body 1, wherein internal electricity connection end 31 is located at the inside of box body 1 simultaneously
It is connect with electrical component, exposed electrical connecting pin 37 is inserted into rubber plug 4, and rubber plug 4 is located in test point mounting hole 5.
Further, as shown in fig. 6, mounting assembly 6 is bolt assembly, bolt assembly more can easily be fixed pre-buried
The position of part 3, it is only necessary to which rotating nuts 61 allow nut 61 close to the side wall of box body 1, and gasket 62 then plays the work for preventing loosening
With.
As shown in fig. 7, being fixed with high-temperature resistant seal ring 38, the diameter of high-temperature resistant seal ring 38 on the first connector 34
It greater than the diameter of the first connector 34, can fully ensure that the gap between built-in fitting 3 and test point mounting hole 5 is filled, prevent
Only the leakproofness of box body 1 is caused to die down due to the test point mounting hole 5 that opens up.
The schematic perspective view of rubber plug 4 as shown in Figure 8, cylindrical cavity 43 are located at the upper of rubber chassis 41
Portion.
As shown in figure 9, cylindrical cavity 43 can wrap up exposed electrical connecting pin 37.To prevent exposed electrical connecting pin
37 it is exposed prevent the exposed electrical connecting pin 37 of the built-in fitting 3 of vapour corrosion copper product in air, prevent it from corroding,
Influence test.Also, rubber plug 4 is filled in test point mounting hole 5, also can guarantee the smooth of 1 surface of box body, guarantees its beauty
It sees.
Further, rubber plug 4 is truncated cone-shaped, can more closely be filled in test point mounting hole 5, abundant exclusion of water
The corrosion of vapour.
In order to verify the test result precision after this device increases test point, with accurate positionin 2 failure of lead wire cable
Comfort level, to being accumulated at the compensation tuned cell structure for not increasing test point of same place, increased the benefit of test point
Ten pairs of compensation tuned cell structures for repaying tuned cell structure in the event of a failure, are counted and are averaged, and are recorded as follows
Shown in table 1:
Table 1
Wherein, actual value is defined as: after removing box body 1, using test equipment to compensation tuned cell internal electric member
The numerical result that part is directly tested.
As shown in table 1, directly lead wire cable 2 is tested using the prior art, the deviation of test value and actual value
Rate is 7.33%, significantly larger than increase test point after, using test equipment directly built-in fitting 3 test it is obtained
3.21% deviation ratio, it is entirely avoided the drawbacks of the variation of inductance caused by 2 change in shape of lead wire cable, it is ensured that whole
The judgement of machine index and the consistency of test result.
In addition, when being occurred by product failure, the comparison of spent time, the time of the determination abort situation of the prior art
It determines that fault time is 5min considerably longer than after increase test point for 21min, has greatly shortened the working time of staff,
It improves work efficiency.
The utility model extracts rubber plug 4, keeps the exposed electrical connecting pin 37 of built-in fitting 3 exposed in test equipment
Outside, the direct test by test equipment to external electricity connection end 37 is conducive to caused by avoiding 2 deformation of lead wire cable
Inductance variation, ensure that the accuracy of test result, also, while increasing test point, utilize refractory seals
Circle 38 and stair-stepping built-in fitting 3 are conducive to steam protection, prevent the test point mounting hole 5 opened up because increasing test point,
Influence the air-tightness of device；In addition, the test point added under the premise of guaranteeing air-tightness, can when product breaks down,
Faster be accurately positioned is failure existing for failure existing for lead wire cable 2 or the electrical component inside box body 1, convenient
Fast.
