Abstract
The utility model discloses a direct-current resistance tester. When the direct-current resistance is tested, a temperature and humidity gauge is additionally arranged on the inner cover of the tester box, so as to enable the testing person to accurately record temperature and humidity in the test environment. The direct-current resistance tester comprises a box cover, a box body and a handle, and is characterized in that the temperature and humidity gauge is arranged at the inner side of the box cover; a temperature pointer and a humidity pointer are arranged on the temperature and humidity gauge, and a scale is marked around each pointer. The direct-current resistance tester has the advantages that as the temperature and humidity gauge is additionally arranged on the inner cover of the tester box, the testing person can accurately record temperature and humidity in the test environment, and test reliability is improved.
Description
Technical field
The utility model relates to a kind of tester of measuring transformer direct current resistance.
Background technology
Transformer Winding direct current resistance m easurem ent is a very important pilot project.< < power equipment testing regulations > > is defined in transformer handing-over, overhaul, light maintenance, change tap joint position, trouble shooting and prerun etc., the direct current resistance of necessary measuring transformer winding.The measurement of direct current resistance can inspection layer between, whether turn-to-turn have or not each position contact of short circuit, shunting switch good etc.Meanwhile, temperature and humidity has a certain impact for the measurement result of direct current resistance, so will record temperature and humidity in DC Resistance of Transformer test.But the instrument for measuring DC resistance using does not have humiture instrument, so testing crew often estimates humiture at the scene, affects integrality and the accuracy of measurement result.
Summary of the invention
The purpose of this utility model be at the scene staff when measuring direct current resistance, by covering and install a thermohygrometer additional in tester chest, make testing crew can accurate recording under the temperature and humidity of experimental enviroment.
For achieving the above object, the technical solution adopted in the utility model is:
, comprise case lid, casing and handle, it is characterized in that: the inner side of case lid is provided with a thermohygrometer above thermohygrometer, having two pointers of temperature pointer and humidity pointer, each pointer is labeled with scale around.
Instrument for measuring DC resistance according to described, is characterized by: on described thermohygrometer, be also labeled with humiture warning line.
The utility model has the advantages that: by covering and install a thermohygrometer additional in tester chest, make testing crew can accurate recording under the temperature and humidity of experimental enviroment, be beneficial to the reliability that improves experiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, case lid; 2, panel; 3, casing; 4, handle; 5, thermohygrometer; 6, temperature pointer; 7, humidity pointer.
Embodiment
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
The utility model is to install thermohygrometer 5 additional at existing instrument for measuring DC resistance chest, records the temperature and humidity while measuring direct current resistance.Thermohygrometer 5 be buckled in tester chest in cover, on thermohygrometer 5 dial plates, mark warning line, for example can use red scale mark to indicate warning scale.On thermohygrometer 5, also fill antisitic defect sheath.This device one is can facilitate staff to check to record humiture, and surpasses suitable detected temperatures, has warning value to indicate; The 2nd, can effectively avoid instrument damage, do not affect outward appearance and the transportation of tester.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineering technical personnel make the technical solution of the utility model, all should fall into protection domain of the present utility model.
