Generally speaking, it is shorter that testing equipment is used for the test wire length of ground connection, and the work place is put far away from special-purpose ground connection ranking simultaneously; Usually ground wire one end of test apparatus is inserted on the earth jack of instrument; The other end is clipped in clip on the earth point of repair apparatus nearby, and this earth point is with a nut ground wire to be tightened fixingly, and surface of contact is very little; Will cause ground connection insecure like this, particularly the staff can't judge whether good earth of earth point intuitively.When many instruments needed ground connection simultaneously, circuit was chaotic, is unfavorable for trouble free service.
The power supply of test apparatus is inserted on three sockets of a power supply cylinder on the other hand, and the plug of cylinder is placed on the indoor wall socket.If the live wire of wall socket and zero line connect instead, live wire and ground wire connect instead, and the power supply of drawing thus is used on the test apparatus, might cause the be short-circuited generation of phenomenon of instrument internal circuit.Especially the testing equipment insulation is bad or aging, the outer casing electrification of equipment at this moment can occur, and direct threats staff's personal safety.
The utility model content
The purpose of the utility model is: to the problem of above-mentioned prior art existence; A kind of porous ground connection and power supply test communication means is proposed; The power supply that has not only guaranteed electrical test equipment is stable; And in use ground connection is reliable can also to guarantee experimental facilities, guarantees the electrical equipment operate as normal.
In order to reach above purpose; A kind of porous ground connection of the utility model and power supply test communication means comprise cabinet and the earth leakage protective device, voltage table, ohmmeter, linked switch, receptacle terminal, first signal lamp and the secondary signal pilot lamp that are arranged in the cabinet; Connect the cable of a band three-pin plug on the said cabinet, the entrance point of said earth leakage protective device links to each other with live wire with the zero line of said cable, and said receptacle terminal links to each other with the endpiece of said earth leakage protective device; The ground wire of said cable links to each other with the ground hole of said receptacle terminal with first signal lamp through linked switch successively, and the ground hole of said receptacle terminal links to each other with the zero line of said cable with linked switch through the secondary signal pilot lamp successively; Said cabinet is provided with is convenient to the earth jack that is connected with ground connection row, and said earth jack links to each other with the ground hole of said receptacle terminal; Be connected with ohmmeter on the said earth jack in turn and link to each other with the ground wire of said cable with linked switch, said voltage table is connected between the zero line and live wire of said cable.
The further qualification technical scheme of the utility model is: aforesaid porous ground connection and power supply test communication means; For the ease of distinguishing failure cause, said first signal lamp and secondary signal pilot lamp are respectively emitting red light diode and yellow light-emitting diode.
Aforesaid porous ground connection and power supply test communication means are provided with current-limiting resistance between said first signal lamp and secondary signal pilot lamp and the linked switch.
Further, aforesaid porous ground connection and power supply test communication means, said receptacle terminal is three sockets.
The invention has the beneficial effects as follows: the utility model provides the multichannel grounding ports and can judge whether dead earthing of grounding ports; Can test equipment for many bench teats good grounding ports is provided simultaneously; The ground wire plug-in mounting is easy to use, and can make multiple devices ground connection simultaneously, and it is clear that test circuit is simplified; Can be through the indication of ohmmeter; Judge directly whether ground connection is good, give one of user signal intuitively, avoid the generation of virtual earth; Can multiple power supplies be provided and can judge the correctness of power supply wiring for experimental facilities; Can provide multichannel reliable power supply for testing equipment simultaneously; The phenomenon of avoiding disorderly connecing power supply takes place, and can detect the zero line and the live wire of power supply intuitively through the indication of voltage table and reddish yellow pilot lamp, and whether the live wire and the ground wire order of connection is correct; Avoid causing the generation of electric shock accidents, guarantee personal safety because of reversal connection.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model profile synoptic diagram.
Fig. 2 is the utility model electrical principle synoptic diagram.
Among the figure: 1 power supply three-pin plug, 2 special-purpose ground wire geometrical clamps, 3 cables, 4 linked switches, 5 earth leakage protective devices, 6 voltage tables, 7 ohmmeters, 8 receptacle terminals, 9 earth jacks, 10 first signal lamps, 11 first signal lamps, 12 cabinets.
Embodiment
