The arrester leak test base of the utility model has advantages of stable structure and reliable grounding, the arrester can be placed vertically in the process of test, so the test data is made more scientific and accurate while ensuring the test security.
Description
Technical field
The utility model relates to the equipment that uses in the leakage current of an arrester test, refers in particular to a kind of base of lightning arrester DC leakage test.
Background technology
The power-frequency voltage of the electrical equipment of Operation of Electric Systems under bearing normal working voltage, sometimes also can be subjected to the effect of instantaneous overvoltage, switching overvoltage and lightning surge.Because the amplitude of lightning surge and switching overvoltage all can surpass the insulation tolerance level of power equipment, under superpotential impact, can make apparatus insulated damage and cause equipment to have an accident.Therefore must take aggregate measures to limit superpotential in the electric system.Lightning arrester is exactly one of electric system Lighting Protection Measures.
Lightning arrester direct current leakage current testing is to be the manufacturing that checks lightning arrester and the quality of installation, and checks the safety case of lightning arrester in the operational process.Be applicable in check, preventive trial and the maintenance process of lightning arrester, for equipment operation, supervision, maintenance provide foundation.
In lightning arrester direct current leakage current testing, owing to lightning arrester is vertically placed and taken measures to guarantee the base reliable ground without corresponding instrument, easily cause certain potential safety hazard in the testing ground.As when testing, because base unstable, be vulnerable to the impact of external force (such as strong wind) and cause and topple over, make the instantaneous over the ground discharge of high pressure, the safety that can jeopardize testing crew when serious.Whether lightning arrester is vertically placed and reliable ground in addition, has also directly affected the accuracy of test figure.
The utility model content
The technical matters that the utility model mainly solves provides a kind of stabilized structure, when test lightning arrester is vertically placed, and guarantees the lightning arrester Leak Off Test (LOT) base of base reliable ground.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of lightning arrester Leak Off Test (LOT) base comprises the triangular supports of a horizontal positioned, the attaching nut of the fixed installation lightning arrester on the triangular supports plane with is connected the ground stud that connects ground wire; Described attaching nut and ground stud are communicated with.
Further improvement of the utility model is: described attaching nut is three nuts that size dimension is different.
Further improvement of the utility model is: the web joint that described attaching nut and ground stud are made by conductive material is communicated with, and web joint is vertical with a limit of the triangular supports of being made by conductive material and be fixedly connected with; The attaching nut is located at the center of triangular supports.
Further improvement of the utility model is: described three nut close-packed arrays triangular in shape together.
Owing to having adopted technique scheme, the obtained technical progress of the utility model is:
The utility model lightning arrester Leak Off Test (LOT) base is a kind of stabilized structure, can make lightning arrester keep the vertical test base of placing when test, and this base is by the ground stud reliable ground, and is safe and convenient to use.
The base of the utility model lightning arrester Leak Off Test (LOT) is triangular supports, and made by conductive material, design makes leg-of-mutton geometrical stability combine with the electric conductivity of metal like this, changed in the in the past test lightning arrester and can't vertically stablize the shortcoming of placing, the while stability of geometric triangulation shape is also brought into play good supporting role.
The design that the base of lightning arrester Leak Off Test (LOT) adopts conductive material and is furnished with ground terminal has been guaranteed to be connected with the reliable of grounded screen.In warranty test safety, make the data science, accurately more in the test of lightning arrester project.Be equipped with in appearance the caution type poster play more arrive attractive in appearance, the caution, safety effect.
The attaching nut is three nuts that size dimension is different, can be used in conjunction with different lightning arresters.
The plate that attaching nut and ground stud are made by conductive material is fixedly connected on the triangular supports, one side on the limit that is fixed on triangular supports of plate, the remainder of plate extends to the inside of triangular supports.Making the attaching nut is the centre that three compact arranged nuts triangular in shape are in triangular supports, and ground stud is on a limit of triangular supports.Lightning arrester is vertically mounted on the attaching nut during use, and lightning arrester just is in the middle part of triangular supports like this, because leg-of-mutton stability makes this support bring into play good supporting role, so lightning arrester can firmly stand vertically on base.The security of test and the reliability of measurement data have further been guaranteed.
Description of drawings
Fig. 1 is lightning arrester Leak Off Test (LOT) understructure schematic diagram.
Wherein: 1, triangular supports, 2 attaching nuts, 3, ground stud.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
A kind of lightning arrester Leak Off Test (LOT) base comprises the triangular supports 1 of a horizontal positioned, is fixed with attaching nut 2 that lightning arrester is installed on the plane of triangular supports 1 and is connected a ground stud 3 that connects ground wire; Wherein triangular supports 1 is made by conductive material.Attaching nut 2 and ground stud 3 are welded on the web joint of being made by conductive material, one side of web joint is welded on the limit of triangular supports 1, web joint extends to the inside of triangular form support 1, make attaching nut 2 be in the center of triangular supports 1, ground stud 3 is positioned at the junction on the limit of web joint and triangular supports.
Attaching nut 2 is three nuts that size dimension is different, and three nut close-packed arrays triangular in shape are co-located at the centre position of triangular supports 1 together.When detecting the lightning arrester of different model, select to be installed on the corresponding nut according to the model of lightning arrester connecting thread, lightning arrester just is upright on the center of base like this.
When carrying out the test of lightning arrester dc leakage-current, at first lightning arrester Leak Off Test (LOT) base is positioned on the smooth ground, with arrestor porcelain bushing surface wiped clean, then according to the suitable nut of the size Selection of lightning arrester, lightning arrester is installed on the selected nut again.By wire ground stud 3 is connected on the grounded screen, and guarantees reliable ground.Adopt high-voltage D.C. generator to carry out test connection, select trial voltage to test according to the electric pressure of lightning arrester.
