Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in more detail.
As it is shown in figure 1, SF6Density monitor test platform includes air-path interface 800 and data communication interface 900；Described air-path interface 800 and SF6The air feed interface 11 of the relay body 1 of density monitor connects, and air-path interface 800 is used for supporting relay body 1；Data communication interface 900 is for being connected by wire with the signals collecting line interface 12 of relay body 1.
As in figure 2 it is shown, be provided for tapping the tapping device of described relay body 1 at relay body 1 away from the side of signals collecting line interface 12 side.And be fixed on positioning base 202 by assembled plate 201 bottom the housing 203 of tapping device；It is fixed on bottom positioning base 202 on test platform 100, can realize tapping the guarantee of height and position by positioning base.Consequently, it is possible to the function rapped can be integrated on test platform, it is also possible to realize rapping test in check test.
As it is shown on figure 3, relay body 1 comprises the drain pan 14 for installing dial plate and for sealing the face shield 15 of drain pan 14；Face shield 15 is transparent material towards user one side；The position of tapping device shock relay body is positioned at the side of described drain pan 14.Can be by the percussion of drain pan be realized measuring the most accurately process, because the core such as dial plate and gear thereof needs the parts measured to be respectively positioned in drain pan, tapping drain pan is to be obtained in that reliable results.
As shown in Figure 4, for SF6The electricity driving displacement tapping device of density monitor test platform, including the housing 203 being fixedly installed on test platform 100, and raps assembly 200 in housing 203；The described assembly 200 that raps includes rapping bar 206 and raps, for driving, the electromagnetic drive that bar 206 moves axially, described in rap and on bar 206, be set with back-moving spring 205, its one end is stretched out outside housing 203, and this end is fixedly connected with tapping head 214.
Operation principle is: electromagnetic drive is energized, and driving is rapped bar 206 and moved, and makes tapping head 214 clash into relay body；Electromagnetic drive power-off, is resetted by back-moving spring 205 and raps bar 206.
