According to the clamp, a cylindrical upper clamping rod of an upper clamp body is fixedly arranged on an upper machine head of a tensile force machine, a cylindrical upper clamping head of the upper clamp body is integrally formed at the lower end of the upper clamping rod, a cylindrical clamping rod of a lower clamp body is fixedly arranged on a lower machine head of the tensile force machine, a cylindrical lower clamping head of the lower clamp body is integrally formed at the upper end of the lower clamping rod, a clamping groove shaped like a circular truncated cone is formed in the middle of the lower clamping head, a connecting groove coaxial with the clamping groove shaped like the circular truncated cone and penetrating through the clamping groove and the upper surface of the lower clamping head is formed in the upper portion of the clamping groove shaped like the circular truncated cone, and the detected disc suspension ceramic insulator is connected between the clamping groove, shaped like the circular truncated cone, of the lower clamping head and the cylindrical upper clamping head of the upper clamp body in a clamped mode. The clamp can accurately detect mechanical performance of the insulator and ensure safe and stable running of a power grid.
Description
Technical field
The utility model belongs to power system device detection technique field, especially a kind of suspension disc insulator Performance Detection special fixture.
Background technology
Suspension disc insulator is important insulating element on transmission line of electricity, and its performance quality is directly connected to mains supply safety.Power system at present takes the method for networking sampling observation to be rigid in checking up to its performance.And in suspension disc insulator mechanical test, often because of complex-shaped bad being installed of insulator.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of suspension disc insulator Performance Detection special fixture.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of suspension disc insulator Performance Detection special fixture, be included in the cylindric upper clamping bar that is fixedly mounted with fixture on puller system on head, be shaped with the cylindric upper grip of fixture in the lower end of upper clamping bar one, under puller system, on head, be fixedly mounted with the cylindric lower clamping bar of lower clamp, be shaped with the cylindric lower chuck of lower clamp in the upper end of lower clamping bar one, be shaped with round table-like clip slot at the middle part of lower chuck, be shaped with coaxial with round table-like clip slot on the top of round table-like clip slot and run through the link slot of clip slot and lower chuck upper surface, tested suspension disc insulator is connected between the round table-like clip slot of lower chuck and the cylindric upper grip of upper fixture.
And the height of described round table-like clip slot and diameter and tested suspension disc insulator steel cap size match, the physical dimension of the height of the cylindric upper grip of described upper fixture and diameter and tested suspension disc insulator steel pin matches.

The utility model can accurately be measured insulator mechanical performance, ensures power network safety operation.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of lower clamp in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is implemented to be further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of suspension disc insulator Performance Detection special fixture, as described in Figure 1, be included in the cylindric upper clamping bar 2 that is fixedly mounted with fixture on puller system on head 1, be shaped with the cylindric upper grip 3 of fixture in the lower end of upper clamping bar one, under puller system, on head 8, be fixedly mounted with the cylindric lower clamping bar 7 of lower clamp, be shaped with the cylindric lower chuck 6 of lower clamp in the upper end of lower clamping bar one, be shaped with round table-like clip slot 5 at the middle part of lower chuck, be shaped with coaxial with round table-like clip slot on the top of round table-like clip slot and run through the link slot 4 of clip slot and lower chuck upper surface, tested suspension disc insulator is connected between the round table-like clip slot of lower chuck and the cylindric upper grip of upper fixture.
In concrete enforcement of the present utility model, because the specification of tested suspension disc insulator is varied, the height of described round table-like clip slot and diameter and tested suspension disc insulator steel cap size match, and the physical dimension of the height of the cylindric upper grip of described upper fixture and diameter and tested suspension disc insulator steel pin matches.
With the upper lower clamp of special shape, the coupling part up and down of fit like a glove electric insulator steel foot and steel cap, ensures vertically deflection not of insulator entirety, thereby reaches the object of Measurement accuracy insulator mechanical performance.
