Abstract
The invention discloses a short-circuit test method of a card holder of a card-inserting electric energy meter. The short-circuit test method comprises the steps of: firstly, inserting a metal sheet being consistent with a user card of the card-inserting electric energy meter in size into the card holder of the electric energy meter to ensure that the metal sheet is in contact with a contact point of the card holder, shortcircuiting the contact point; secondly, applying a working voltage to the card-inserting electric energy meter, if the card-inserting electric energy meter normally works, judging that the card-inserting electric energy meter is qualified; and if the card-inserting electric energy meter is halted or in a blank screen, judging that the card-inserting electric energy meter can not resist the short-circuit attack and is not qualified. A card-reading contact embedded in the card holder is short-circuited by inserting the metal sheet, therefore, the short-circuit attack resistance capacity of the card-inserting electric energy meter can be conveniently tested, and the testing efficiency is greatly increased.
Description
Technical field
The present invention relates to a kind of card insert type electric energy meter deck short circuit test method.
Background technology
In card insert type electric energy meter application process, the individual user inserts tinsel or sheet metal at the card inserting mouth of deck, thereby the card reader short circuit that deck is embedded causes the ammeter can't operate as normal, causes the power stealing leaky.Because the user is the card inserting mouth destruction ammeter internal circuit through deck, destroys the lead sealing of mark meter, when handling analogue, can't confirm the party responsible, has brought enormous economic loss to electric power enterprise.For fear of this situation, now general way is to take electric energy meter apart, adopts the electric shock short circuit with deck of lead or bare copper wire then, thus test electric energy meter deck the Short Circuit withstand attacking ability, this method efficient is lower, is not suitable for applying.
Summary of the invention
The technical matters that the present invention will solve provides a kind of easy to use, card insert type electric energy meter deck short circuit test method that efficient is higher.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is: a kind of card insert type electric energy meter deck short circuit test method, and the step of said method is:
1) will be inserted in the ammeter deck with card insert type electric energy meter subscriber card sheet metal of the same size, and sheet metal contacted, with the contact of deck its short circuit;
2) add work voltage for the card insert type electric energy meter, if its ability operate as normal, it is qualified then should to show; If its deadlock or blank screen, then this table can not be resisted the short circuit attack, and it is defective.
Above-mentioned sheet metal material is stainless steel or aluminium flake, and its length and width, gauge are 86mm * 55mm * 0.9mm.
Adopt the beneficial effect that technique scheme produced to be: the present invention is through inserting the sheet metal Card Reader contact short circuit that deck is embedded; Thereby can test the Short Circuit withstand attacking ability of card insert type electric energy meter deck easily; Avoid the deck of card insert type ammeter to measure because of the table that short circuit causes; Economic loss to electric power enterprise brings simultaneously compared with existing deck short circuit test method, can improve detection efficiency greatly.
Embodiment
The concrete steps of the method that the present invention adopted are:
1) adopt stainless steel or aluminium flake to make a sheet metal; The size of sheet metal and intelligent electric energy meter subscriber card are measure-alike, and (length and width, gauge are 86mm * 55mm * 0.9mm); Then this sheet metal is inserted in the electric energy meter deck; Sheet metal is contacted, with the contact short of deck with the contact of deck;
2) add work voltage for then the card insert type electric energy meter, make the card insert type electric energy meter in running order, if the table meter is in proper working order, it is qualified then should to show, and it is described can resists the deck short circuit and attack; If its deadlock or blank screen, judge that then its deck can not resist short circuit and attack, it is defective.Underproof table meter is directly return producer changes, avoided the hypodynamic table meter of deck Short Circuit withstand impact energy to put into operation, for enterprise avoided enormous economic loss and and the user between dispute.
Claims (2)
1. card insert type electric energy meter deck short circuit test method, it is characterized in that: the step of said method is:
1) will be inserted in the ammeter deck with card insert type electric energy meter subscriber card sheet metal of the same size, and sheet metal contacted, with the contact of deck its short circuit;
2) add work voltage for the card insert type electric energy meter, if its ability operate as normal, it is qualified then should to show; If its deadlock or blank screen, then this table can not be resisted the short circuit attack, and it is defective.
2. card insert type electric energy meter deck short circuit test method according to claim 1, it is characterized in that: said sheet metal material is stainless steel or aluminium flake, its length and width, gauge are 86mm * 55mm * 0.9mm.
