Description
Technical field
The invention belongs to technical field of electronic products, be specifically related to a kind of clamp on amperemeter with dust arrester.
Background technology
Clamp on amperemeter is to be combined by current transformer and ammeter.The iron core of current transformer can open when clutching spanner, and the wire that tested electric current passes through can cut off and may pass through the breach that iron core opens, when decontroling spanner back core Guan Bi.When measuring electric current typically by common current table, it is necessary to ammeter could being accessed measurement after circuitry cuts being shut down, this is pretty troublesome, and sometimes properly functioning motor does not allow do so.Now, clamp on amperemeter is used just to seem more convenient, it is possible to measure electric current when not cutting off circuit.
Just become the primary winding of current transformer through circuit-under-test wire unshakable in one's determination, wherein in secondary coil, just induce electric current by electric current.So that the ammeter that secondary coil is connected just has instruction to measure the electric current of test line.Pincerlike meter by the fork shift of permutator, can change different ranges, but do not allow charged being operated during fork shift.Pincerlike meter common accurate is not high, is generally 2.5～5 grades.In order to easy to use, also has the permutator of different range in table for surveying different brackets electric current and measuring the function of voltage.
When detecting electric current with clamp on amperemeter, a tested wire (electric wire) must be sandwiched and sandwich two (parallel lines) and then can not detect electric current.It addition, when using clamp on amperemeter center (iron core) detection, detection error is little, when checking the power consumption of household appliances, using line trap more convenient, some line traps can by detection Current amplifier 10 times.Therefore the electric current of below 1A can detect after amplifying again, when detecting DC current (DCA) with direct current clamp on amperemeter, if the flow direction of electric current is contrary, then demonstrates negative, and the accumulator that can use this Function detection automobile is charged state or discharge condition.
The clamp on amperemeter of meansigma methods mode is by exchanging detection, the meansigma methods that detection is sinusoidal wave, and the value after amplifying 1.11 times (sine wave ACs) is shown as virtual value, the waveform beyond sine wave that waveform rate is different and askew ripple show after amplifying 1.11 times too, so index error can be produced, when therefore detecting the waveform beyond sine wave and askew ripple, the clamp on amperemeter that can directly test out real effective please be select.
Detection of electrical leakage is different from common current detecting, and two (single-phase 2 wire types) or three (single-phase 3 wire types, three-phase 3 wire types) all to clamp.Also can clamp earth lead to detect, low-voltage circuit detects the insulation management method of leakage current, become primary judging means, since it is confirmed by (correction of electrical equipment technical standard in 1997), in the building that can not have a power failure and factory, leakage current split-core type meter is just gradually adopted to detect.
Existing clamp on amperemeter function is gradually improved, and function diversification, but with regard to practicality or unsatisfactory, is often required to corresponding electric appliance is carried out dedusting in detection inspection process；The dust arrester function that tradition clamp on amperemeter does not carry, causes very adverse effect to the efficiency of detection and testing result, and usual dedusting adopts hands to wipe or mouth blows, and not only effect is bad, it is also possible to endanger the health of oneself.
