In spark gap direct current leakage current testing, owing to carrying out being disposed vertically and take measures to ensure base reliable ground by spark gap without corresponding instrument, easily cause certain potential safety hazard in testing ground.As when testing, due to the instability of base, it is vulnerable to the impact of external force (such as strong wind) and causes and topple over, make that high pressure is instantaneous to discharge over the ground, the safety of testing crew time serious, can be jeopardized.Additionally whether spark gap is disposed vertically and reliable ground, also directly affects the accuracy of test data.
CN202649243 U proposes a kind of spark gap leak test base, its general configuration is the connecting plate of the upper surface one piece of rectangle of welding on one limit of triangular supports of horizontal positioned, connecting plate welds three attaching nuts and a ground stud, three nut centers being arranged closely together and be positioned at triangular supports triangular in shape.This base can detect the spark gap of three different sizes simultaneously, and these three specification is specific, does not possess versatility.And the spark gap specification of different manufacturers, different model and batch is a lot, so the practicality of this base is the highest.Additionally, due to the connection screw rod of spark gap at two ends, its main by weight concentrates on the interlude of band shirt rim, this base is acted foolishly fixing each spark gap to by the connection of nut Yu screw rod, balance is kept by mutually supporting between three spark gaps, and, attaching nut is positioned at the inner of connecting plate, and the inner of connecting plate is in vacant state, so defect unstable after spark gap connects will necessarily be there is, so that test process is dangerous and test data are inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of universal really can realize the Test bench that spark gap vertically fixedly secures, to meet spark gap safety in test process and to ensure the accuracy of test data.
The utility model discloses a kind of universal test base of 10kV spark gap, including the Base body of metal material and be connected to some support columns of Base body upper end, the short transverse center position of each support column has circular hole, the corresponding position of Base body has aperture to be less than the installing hole in support column center position circular hole aperture, Base body reliable ground.
As preferably, the cuboid-type housing that described Base body uses bottom surface to be open side, its Sidewall Height is less than the length and width size of top board.
As preferably, described Base body uses stainless-steel sheet to make.
As preferably, described support column is axially hollow annulus, and its external diameter is less than the external diameter of spark gap full skirt, and the aperture of its axial central through hole is more than the core outside diameter of spark gap.
As preferably, the quantity of described support column is six, and the top board length direction along described Base body is that two rows are uniform.
As preferably, the installing hole at the corresponding each support column of described Base body is circular hole, and its aperture is more than the maximum gauge value connecting screw rod of 10kV spark gap series.
As preferably, the top board of described Base body being vertically connected with bolt by corner, earth lead is connected between the screw rod head of bolt and the contact surface of Base body, and the body of rod of bolt is fastened by nut, to ensure the reliable ground of Base body after top board.
This utility model, by arranging support column in Base body, is connected the screw rod of spark gap end, is supported a piece of full skirt in bottom of spark gap by the upper end of support column by the installing hole in support column central hole Base body.When spark gap is fixed, only the screw rod of its lower end need to be inserted in the installing hole in Base body, make to be placed on the upper surface of support column under a piece of full skirt in bottom of spark gap, then by locking nut, screw rod is connected as one with Base body.So, the vertical stability of the spark gap after fixing is fine, the most fine with the connection contact performance of Base body.What i.e. spark gap can be the most stable is fixed in Base body, thus realizes spark gap safety in test process and ensure the purpose of test data accuracy.
In order to improve the work efficiency of this pedestal, multiple support column can be connected on pedestal, carry out the performance test work of multiple spark gap simultaneously, simultaneously take account of this pedestal easy to carry, the quantity of support column is set to about six.
In order to make Base body can be easy to the good ground connection of horizontal positioned, work efficiency can be improved again as far as possible, the cuboid-type housing that Base body uses bottom surface be open side, and make its height dimension be easy to the fastening of screw rod top nut when spark gap connects.
In order to ensure the reliable ground of whole pedestal, the top board of Base body vertically connects screw rod, so earth lead only need to be connected between the screw rod head on screw rod and the contact surface of Base body, is integrated with Base body locking by screw rod by nut, easy to operate.
