Description
Technical field
The utility model belongs to a kind of support insulator pick-up unit, is applicable to test or detects the response condition of support insulator to certain impact load.
Background technology
At present, power industry is with support insulator in the time carrying out mechanical property test, and research technique all carries out as basis taking static mechanical performance test.Envelope test means, through development for many years, have formed perfect standards system and test method, and have been widely accepted.But in the actual moving process of support insulator, what bear for the support insulator of disconnector and breaker portion is mainly the shock load of repetition, its load character and static mechanical test difference are larger.Especially the in the situation that of switch repetitive operation, the fatigue properties of support insulator under circulation impact load cannot be passed through static mechanical performance test effecting reaction.
By designing a kind of mechanism of simulating shock load, support insulator is carried out to shock load simulation test, can effectively understand by research technique the ability of support insulator resistance to shock loads, investigate its fatigue properties under circulation impact load, assessment support insulator impulse fatigue resistance energy simultaneously.
Summary of the invention
The utility model provides a kind of support insulator shock load simulation test device, and this device is made up of sample erecting bed, surge generator, mounting adapter and safety cradle.For support insulator sample is applied to simulation shock load, to check its impulse fatigue resistance or to test its resistance to shock loads ability.
The above-mentioned test unit course of work is as follows: sample erecting bed is fixed on ground by foot bolt, test specimen support insulator is secured by bolts on sample erecting bed, safety cradle is installed on test specimen support insulator upper flange position, and impact adapter and the shock load generator of installing on adapter are arranged on support insulator by bolt; Shock load generator is also connected with drive pulse generator.Drive pulse generator is responsible for generating electric pulse, and electric pulse is converted to mechanical pulsing via shock load generator, and passes to test specimen support insulator along impacting adapter, makes test specimen support insulator be subject to mechanical impact load.The pulse parameter and the installation site of shock load generator on impact adapter that generate by adjusting drive pulse generator, the shock load size that can regulate sample to be finally subject to.When test specimen support insulator can not withstand shocks load when fracture, safety cradle by constraint live in flange and be mounted thereon hit adapter and shock load generator, the equipment that prevents is born causes damage.
Effect of the present utility model is, by using such test unit, can directly investigate the response condition of support insulator to all size shock load, resistance to shock loads ability and impulse fatigue resistance energy that can more effective reflection support insulator.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Wherein numbered block is as follows: 1-sample holder; 2-foot bolt; 3-test specimen (support insulator); 4-protective device and lanyard; 5-adapter; 6-impact transducer; 7-drive pulse generator.
Embodiment
A kind of support insulator shock load simulation test device, comprise with lower component: sample erecting bed 1 is fixed on ground by foot bolt 2, test specimen support insulator 3 is secured by bolts on sample erecting bed 1, safety cradle 4 is installed on test specimen support insulator 3 upper flange positions, and impact adapter 5 and the shock load generator 6 of installing on adapter are arranged on support insulator 3 by bolt; Shock load generator 6 is also connected with drive pulse generator 7.Drive pulse generator 7 is responsible for generating electric pulse, and electric pulse is converted to mechanical pulsing via shock load generator 6, and passes to test specimen support insulator 3 along impacting adapter 5, makes test specimen support insulator 3 be subject to mechanical impact load.The pulse parameter and the installation site of shock load generator 6 on impact adapter 5 that generate by adjusting drive pulse generator 7, the shock load size that can regulate sample 3 to be finally subject to.When test specimen support insulator 3 can not withstand shocks load when fracture, safety cradle 4 by constraint live in flange and be mounted thereon hit adapter 5 and shock load generator 6, the equipment that prevents is born causes damage.
