Formula live detection technology is applied to the state-detection of power transmission and transforming equipment, and the detection that do not has a power failure is increasingly becoming possibility.Electrical network power transmission and transformation set
Standby status assessment data source increasingly lays particular emphasis on the result of the test of live detection, the accuracy of live detection data and degree of accuracy
Particularly important.Power system generally use clamp on amperemeter carry out iron core grounding current live detection, although pincerlike meter precision is relatively
High but be highly prone to on-the-spot electromagnetic interference, there is jump phenomena in detection numerical value, extremely unstable, affects testing result.Therefore,
A kind of power transmission and transformation high precision electro current test table is we have proposed for the problems referred to above.
Utility model content
Having problems for above-mentioned prior art, this utility model provides a kind of power transmission and transformation high precision electro current test table, and electric energy meter has
There is electro-magnetic shielding cover, the significant increase capacity of resisting disturbance of testing current table, solve problem present in background technology.
For achieving the above object, the technical solution adopted in the utility model is: a kind of power transmission and transformation high precision electro current test table, including
Shell and be arranged on the pincerlike iron core of housing top end；Electro-magnetic shielding cover, and electro-magnetic shielding cover are installed in the side of described pincerlike iron core
It is welded on housing top end；Between described shell and electro-magnetic shielding cover, handle is set；The bottom of described shell is provided with display screen, and institute
State surrounding's installation function key of display screen；Measurement range selection knob, and measurement range selection rotation are set between described function key and pincerlike iron core
Button is arranged on shell.
Further, described function key has six, and the area of function key is 1/6th of display screen.
Further, described pincerlike iron core is two semicircular structures.
Further, the diameter of described electro-magnetic shielding cover is more than the diameter of pincerlike iron core.
Further, it is slidably connected between described handle and described shell.
The beneficial effects of the utility model are: this kind of power transmission and transformation high-precision current list structure is compact, it is simple to carry, simple to operate,
Easy to use, safe and reliable, it is not necessary to outage detection, elevator belt electro-detection level, the anti-electromagnetism of testing current table can be effectively improved and do
Disturb ability such that it is able to measure current value accurately and stably, improve accurate testing degree.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
In figure: 1, electro-magnetic shielding cover, 2, handle, 3, shell, 4, function key, 5, display screen, 6, measurement range selection knob,
7, pincerlike iron core.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear,
It is fully described by.Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
Based on the embodiment in this utility model, the institute that those of ordinary skill in the art are obtained under not making creative work premise
There are other embodiments, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, a kind of power transmission and transformation high precision electro current test table, including shell 3 and the pincer that is arranged on shell 3 top
Iron core 7；Electro-magnetic shielding cover 1 is installed in the side of described pincerlike iron core 7, and electro-magnetic shielding cover 1 is welded on shell 3 top；Described
Handle 2 is set between shell 3 and electro-magnetic shielding cover 1；The bottom of described shell 3 is provided with display screen 5, and described display screen 5
Installation function key 4 around；Between described function key 4 and pincerlike iron core 7, measurement range selection knob 6, and measurement range selection knob 6 are set
It is arranged on shell 3 side.
As optimisation technique scheme of the present utility model: described function key 4 has six, and the area of function key 4 is display screen 5
1/6th；Described pincerlike iron core 7 is two semicircular structures；The diameter of described electro-magnetic shielding cover 1 is more than pincerlike iron core
The diameter of 7；It is slidably connected between described handle 2 and described shell 3.
This utility model in use, makes pincerlike iron core 7 and electro-magnetic shielding cover 1 open, by tested current-carrying by pressing handle 2
Wire is placed on electro-magnetic shielding cover 1 the rectangle hole left, when having alternating current to pass through in tested wire, alternating current
Magnetic flux induces electric current in transformer vice-side winding, and this electric current passes through change-over circuit, the measured current value of display on display screen 5,
After tested wire is put into jaw, it should be noted that there is good coincideing in two faces of jaw, it is impossible to allow other object in centre.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and not
