Transformer dc resistance test instrument is an indispensable test project of Transformer after handing in pick up overhaul and change sub-pick up switch. In general using traditional methods (bridge method and pressure drop method) measurement transformer winding group and dc resistance of large power inductance equipment is a time-consuming and time-consuming work. In order to change this situation shorten measurement time and reduce the work burden of test personnel huatian electric power company developed Transformer dc resistance test instrument (hereinafter referred to as direct resistance instrument). It adopts new power supply technology featuring stable performance rapid measurement small volume easy to use high measurement precision and good data repeatability. Measurement transformer around the group and large power inductor dc resistance ideal equipment.

Dc resistance around the group of measurement transformers 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 names Dc resistance tachometer Transformer dc resistance test instrument Transformer direct resistance speed meter Transformer direct resistance quick test instrument Inductive load Dc resistance tachometer Inductive load dc resistance rapid test instrument Inductive load dc resistance test instrument Dc resistance rapid test instrument
The test transformer calls the booster it is the basic test equipment used by the power station supplying and distributing the electrical power system and the scientific research unit. Which used in the insulated intension test on all kinds of electrical products electrical equipments and insulated materials testing the insulated level of products discovering the insulated objection of quizzee scaling the capacity burdened voltage AC HV Testing Transformer Classification: There are four kinds of high voltage testing transformer according to the medium points: 1. Oil-immersed high voltage transformer test: large capacity, cheap, convenient maintenance, mainstream products. 2. Inflatable high voltage test transformer : interrupter resistance, and light weight. 3. Dry type high voltage testing transformer: light weight, light volume, can run backward, price expensive. 4. Series type high voltage testing transformer: small volume, low voltage, light weight, easy to transport and install.
