Product Introduction

Dc resistance around the group of measurement transformer is a very important test project. In the "test regulations of electric power equipment" its order ranks the second in the transformer test project. The "regulations" stipulates that pick up overhaul minor repair change sub-pick up head position fault check and pre-test etc. should be done in transformer. Measurement transformer must have dc resistance around the group whose purpose is:

(1) check the welding of line and lead line around the group;

(2) check if the pick up touch is good;

(3) check whether there is a broken place around the group or leading line;

(4) check the correctness of the parallel branch whether there is a few parallel guide lines winding into the winding group or a few broken line situation;

(5) check whether there is a short circuit between layers and turns.

The interface design of Dc resistance rapid test instrument adopts microcomputer control big screen backlit Chinese liquid crystal screen show operation is simple show clear man-machine interaction interface friendly measurement process and instrument work state prompt is clear and sufficient no operation personnel need to memorize too many procedures; Huatian electric power adopts current source line-based compensation technology with stable test high measurement precision and fast speed improving measurement efficiency and reducing work intensity of operation personnel. Technically "four-end" measurement is adopted to eliminate the measurement error caused by line resistance with pick up contact. Overvoltage protection function can resist electric potential impact. Panel printer can print measurement results quickly (selected). Small size light weight easy to carry.

Dc resistance rapid test instrument is applicable to measurement with analysis of various electric transformer transformer winding group and other perceptual low resistance.

Product Characteristics

1、Test fast: Dc to hold rapid test instrument maximum charging current can be up to 5 a when the measurement is effective to compensate large inductance equipment current inertia It accelerates the core saturation thus shortening the charging time and improving the test speed It is hundreds of times faster than traditional instrument single and double arm bridge
2、High accuracy: Dc resistance rapid test instrument not only adopts the advanced four-terminal measurement method but also adopts the advanced constant current power supply technology so that the current of inductive load charging is kept at a relatively stable value with stable sensitivity resistance and strong anti-interference ability thereby ensuring the measurement accuracy. Besides high-quality components imported from abroad are adopted with high measurement result accuracy and good repeatability
3、Measuring range wide： resistance measuring range1μΩ～20kΩ， range wide
4、Deliver dc dual-use: dc resistance rapid test instrument is attached with rechargeable battery group deliver dc power supply portable design easy to use and carry
