Cable accessory gold utensil is HV cable accessories gold utensil particularly, and its enough physical strength is the prerequisite that ensures cable accessory effective sealing, thereby has guaranteed the insulating property of cable accessory.
At present, the design of cable accessory gold utensil can obtain by theoretical Calculation and Analysis of Force in physical strength, and whether its theoretical value can meet the requirement of cable accessory practical application can be verified by pressure testing machine.But for HV cable accessories gold utensil, for example top cover, base plate, snap ring etc., physical dimension is larger mostly, and conventional pressure testing machine cannot meet in suitable dimensions.The pressure testing machine of selecting large specification, experimentation cost is high; Be arranged in a whole set of HV cable accessories and verify, waste time and energy.
Summary of the invention
The purpose of this utility model is in order to address the deficiencies of the prior art, design a kind of HV cable accessories gold utensil physical strength demonstration test device, HV cable accessories gold utensil physical strength demonstration test can be realized simple and effectively, reduced near the cost of the gold utensil physical strength demonstration test of high-tension cable simultaneously.
The utility model is achieved in that a kind of HV cable accessories gold utensil physical strength demonstration test device, it is characterized in that: by base plate and panel two ends are with bolts, become a groined type framework test stand 1, double acting hydraulic cylinder 3 is placed in the center of test stand 1, double acting hydraulic cylinder base is seated in test stand 1 base plate center, double acting hydraulic cylinder 3 sidepieces connect high-pressure pipeline 9 and the first hydraulic hand-pump 10, the second hydraulic hand-pump 11, hydralic pressure gauge 8, the radial position of double acting hydraulic cylinder 3 adopts and is bolted on test stand 1 base plate, test fitting 5 is adopted and is bolted on fixed head 2 by cushion block 7, double acting hydraulic cylinder 3 is made mechanical strength test by jacking block 4 to test fitting 5, test fitting 5 measurement faces are provided with the dial gauge of the deformation numerical value that in reflection test, test fitting 5 produces, 8 of hydralic pressure gauges show the mechanical strength value applying in test.Shape, size and the thickness of described cushion block 7 are determined according to the shape of test fitting 5, and jacking block promotes to move upward to contact with test fitting 5 bottom surfaces by double acting hydraulic cylinder piston.
The beneficial effects of the utility model are: the utility model is applicable to the physical strength demonstration test of 110kV and above HV cable accessories gold utensil, and the test of suitable for various size size gold utensil, there is versatility, HV cable accessories gold utensil physical strength demonstration test can be realized simple and effectively, reduce existing experimentation cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, test stand; 2, fixed head; 3, double acting hydraulic cylinder; 4, jacking block; 5, test fitting; 6, bolt; 7, cushion block; 8, hydralic pressure gauge; 9, high-pressure pipeline; 10, the first hydraulic hand-pump; 11, the second hydraulic hand-pump.
Embodiment
With reference to the accompanying drawings, a kind of HV cable accessories gold utensil of the utility model physical strength demonstration test device becomes a groined type framework test stand 1 by base plate and panel two ends are with bolts, double acting hydraulic cylinder 3 is placed in the center of test stand 1, double acting hydraulic cylinder 3 bases are seated in test stand 1 base plate center, double acting hydraulic cylinder 3 sidepieces connect high-pressure pipeline 9 and the first hydraulic hand-pump 10, the second hydraulic hand-pump 11 and hydralic pressure gauge 8, the radial position of double acting hydraulic cylinder 3 adopts and is bolted on test stand 1 base plate, test fitting 5 is adopted and is bolted on fixed head 2 by cushion block 7, double acting hydraulic cylinder 3 is made mechanical strength test by jacking block 4 to test fitting 5, test fitting 5 measurement faces are provided with the dial gauge of the deformation numerical value that in reflection test, test fitting 5 produces, 8 of hydralic pressure gauges show the mechanical strength value applying in test.Shape, size and the thickness of described cushion block 7 are determined according to the shape of test fitting 5, and jacking block promotes to move upward to contact with test fitting 5 bottom surfaces by double acting hydraulic cylinder piston.Fixing of the applicable large scale test fitting of fixed head 2.Jacking block 4 and cushion block 7 are Replacement Part, according to corresponding test fitting, are used in conjunction with.
Before test, first jacking block 4 is placed on fixed head 2, with bolt 6, cushion block 7 and test fitting 5 is fixed on fixed head 2 subsequently, then dial gauge is arranged on the measurement face of test fitting 5.During test, start the second hydraulic hand-pump 11 and make double acting hydraulic cylinder 3 actions, thereby impel the piston of double acting hydraulic cylinder 3 pushing away jacking block 4, slowly move upward.When jacking block 4 touches test fitting 5, the inner beginning of oil cylinder supercharging.Under the continuation effect of the second hydraulic hand-pump 11, the inner pressure producing of hydraulic cylinder is delivered on test fitting 5, makes test fitting 5 stressed.The reading of hydralic pressure gauge has reflected the stressed size of test fitting 5 indirectly.The reading of dial gauge directly reflects elastic deformation and the plastic yield situation in test fitting 5 loading processes.
The feature of the utility model test unit is: can meet the test of large scale gold utensil.Adopt conventional hydraulic tool output test power, convenient effective.By changing the test of jacking block 4 and cushion block 7 all right suitable for various size size gold utensils, there is versatility.Fixing and the force way simulation gold utensil real use state of test, makes the result more convincing.
