Carrying out insulating sheath air insulation distance when experimental, during the insulating sheath that will bond penetrated conductor [ 3 ], the spring structure of conductor [ 3 ] compressed tightly outer contact [ 31 ] with insulating sheath, adjust horizontal non -conductive support rod [ 2 ] and insulating sheath between distance to test distance, with grounding body [ 4 ] the ground connection on the horizontal non -conductive support rod [ 2 ], exert the air insulation distance 0 of test voltage in order to detect insulating sheath for the transmission line on inboard conductor [ 33 ].
Description
Technical field
The utility model relates generally to insulating sheath used for transmission line, refers in particular to a kind of insulating sheath test unit used for transmission line, may be used for the air insulation distance withstand voltage test of 110kV and 220kV circuit insulating sheath.
Background technology
Along with the mankind more and more focus on environmental protection, wild animal living environment is become better and better, and birds quantity gets more and more.Power grid construction paces are more and more faster simultaneously, and transmission line of electricity is more and more intensive, and birds are movable also increasing on the impact of electrical network.Transmission line of electricity presents because relating to bird fault the trend increased year by year, and the safe operation of electrical network in serious threat.Chinese scholars, to relating to bird failure cause and birds habit has carried out deep research, will relate to bird fault and be summarized as and to cause when large shape bird spreads the wings that air gap distance is not enough, bird excrement causes insulator surface to pollute and then cause insulator edge flashing 3 kinds at insulator by defecation on time of tide generation flashover and the large birds cross-arm.
In order to prevent 110kV and 220kV circuit birds droppings flashover, the more measure of present employing for installing bird-resistant, anti-bird baffle plate and using Intelligent bird expelling device etc. on shaft tower, these measures are all prevent bird to drop on shaft tower defecation to solve circuit because of birds droppings flashover, but still have in actual applications because device Rig up error causes the event of line tripping to occur.Have employed again a kind of new measure at present, installing insulating sheath on the line, prevents birds droppings flashover with the insulating property increasing circuit.But for the withstand voltage test of insulating sheath, need require to carry out according to the air insulation distance test (DT) of GB/T3408.8-2007 " electric wire method for testing performance the 8th part: AC voltage test ", in its process of the test, find that insulating sheath contacts with pressure rod not tight, the problems such as air insulation distance adjustment difficulty, in order to solve the problem, devise a kind of insulating sheath test unit used for transmission line newly.
Summary of the invention
In order to the shortcoming that the lack of standard and detection efficiency that solve insulating sheath used for transmission line test are low, the utility model is intended to design a kind of insulating sheath test unit used for transmission line, with the distance test (DT) of specification insulating sheath air insulation used for transmission line, improve insulating sheath used for transmission line test efficiency, reduce the labour intensity of staff.
The technical solution adopted in the utility model is:
When carrying out the distance test (DT) of insulating sheath air insulation, bonding insulating sheath is penetrated in conductor, outer contact and insulating sheath compress by the spring structure of conductor, regulate level insulation support bar and distance between insulating sheath to test distance, by the grounding body ground connection on level insulation support bar, inner conductor applies trial voltage to detect the air insulation performance of insulating sheath used for transmission line.
Described one insulating sheath test unit used for transmission line, its conductor is by outer contact, and spring and inner conductor form.
Described one insulating sheath test unit used for transmission line, its level insulation support bar can move up and down along vertically insulated support bar.
Described one insulating sheath test unit used for transmission line, the distance between its two vertically insulated support bars is greater than 1.5m.
The utility model is adopted to have following advantage:
1, conductor is by outer contact, outer contact can be adjacent to inner conductor by spring and inner conductor composition, facilitate penetrating of insulating sheath used for transmission line, after insulating sheath used for transmission line penetrates insulating sheath, spring is opened, outer contact can be close to insulating sheath.
2, level insulation support bar can move up and down along vertically insulated support bar the adjustment facilitating air insulation distance.
3, the spacing of two vertically insulated support bars is greater than 1.5m, can prevent in test conductor from docking conductive discharge.
In sum: a kind of insulating sheath test unit used for transmission line may be used for the accuracy improving insulating sheath used for transmission line test, also improves the efficiency of insulating sheath used for transmission line test simultaneously, reduces the labour intensity of testing crew.
