Description
Technical field
The utility model belongs to power supply, distribution technique field.
Background technology
Electric energy meter seal, wilful damage power supply enterprise electricity consumption WT-MSR, employing additive method that the electricity consumption scene often has the lawless person to forge or open power supply enterprise and seals up deliberately make the inaccurate perhaps inefficacy of power supply enterprise's electricity consumption WT-MSR and carry out stealing; Endangered confession electricity consumption order; Cause state-owned assets to run off in a large number, also grievous injury the interests of power supply enterprise.When the power utility check personnel checked single-phase electric energy meter at the scene, whether owing to there is not the detecting instrument of portable load equipment and specialty, it was normal therefore to be difficult in time to judge the electric energy meter operation.
Summary of the invention
The purpose of the utility model be exactly provide in order to overcome the above problems a kind of field by using load method fast detecting go out the single-phase electric energy meter operation whether normal, have easy and simple to handle, be easy to the single-phase electric energy meter on-site detector that overhauls and safeguard.
The technical scheme of the utility model is design like this: a kind of single-phase electric energy meter on-site detector is characterized in: it comprises casing 10, is loaded on testing circuit, test pencil in the casing 10; Casing 10 vertically divides three interlayers separated: promptly the measurement test pencil on the left side and electrician's utensil at interval 7, middle switchgear and circuit at interval 8, the 1kW pure resistor load interval 9 on the right; Two meter penholder holes 1, nonstick button switch 2, power light 3, voltage table 4, reometer 5 are housed measuring the upper surface of test pencil with electrician's utensil interval 7; Switchgear and circuit 8 upper surfaces at interval are equipped with portable handle 6; 1kW pure resistor load 9 right surface at interval is provided with plexiglass window 11; Testing circuit is to be connected with the parallel branch of voltage table by fuse, power light, RCCB, reometer, 1kW pure resistor load to constitute.
The utility model is to adopt the load method to detect single-phase electric energy meter, and cost is low, easy to use, be easy to carry; Whether being easy to fast detecting, to go out single-phase electric energy meter operation normal, is convenient to site examining and repairing and maintenance.
