Abstract
The utility model relates to an electrical detection assisting device, in particular to an electrical zero-electric and zero-magnetic interference detection device. The electrical zero-electric and zero-magnetic interference detection device consists of a metal box body, an inner bottom insulating plate, a grounding wire and a circuit pipeline, wherein four sides of the metal box body are closed, the metal box body is made of steel plates, the inner bottom insulating plate is arranged on the ground in the metal box body, a metal grounding wire is arranged outside the metal box body, and the circuit pipeline which is a metal pipe is arranged on the side surface of the metal box body. The electrical zero-electric and zero-magnetic interference detection device is convenient to move and is hardly interfered.
Description
Technical field
The utility model relates to electric power and detects servicing unit equipment, is specially a kind of electric power zero electromagnetic interference detecting device.
Background technology
Present power equipment detects as equipment directly carries out work to ready-made, and the large voltage of power transmission and transformation power is high, and the radiation field that produces in environment at the scene is very strong, and is large to the Accuracy of equipment, causes data distortion.In detection, one is to need the band electro-detection to obtain data, the 2nd, and the data that have after outage can't record.
Summary of the invention
This patent provides a kind of electric power zero electromagnetic interference detecting device for above technical matters, and purpose is to obtain to get rid of the accurate measurement data of interference acquisition of electric current electromagnetic field.
The concrete technical scheme of this patent is as follows:
Electric power zero electromagnetic interference detecting device, formed by metal cabinet, insulcrete of the interior end, ground wire, cable tubing, it is characterized in that: metal cabinet seals on four sides, the material of metal cabinet is steel plate, in metal cabinet, ground arranges insulcrete of the interior end, metal cabinet arranges the metal ground wire outward, and the side of metal cabinet arranges cable tubing, and cable tubing is metal tube.
Metal cabinet is arranged on the truck rear portion, move with car, place the electric power pick-up unit in metal cabinet, the electric power pick-up unit is placed on insulcrete of the interior end, the data connecting line of electric power pick-up unit passes cable tubing and is connected with outside, after arriving at detection site, the outer metal ground wire that arranges of metal cabinet carries out the ground connection operation.The utility model is convenient mobile, is disturbed few.Because the bulk metal of metal cabinet, the middle electromagnetic interference (EMI) of environment can't break through to inside, is not vulnerable to the interference of the problems such as electromagnetic field, has realized the relatively accurate of detection.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of this patent.
Wherein, 1---metal cabinet, 2---insulcrete of the interior end, 3---ground wire, 4---cable tubing.
Embodiment
Below in conjunction with embodiment, this patent is described further.
