Abstract
The utility model discloses an intelligent electronic digital anti-electric larceny measuring pocket used for distribution transformer outlet electric power total measuring, and comprises a measuring pocket body, a pocket door, a door lock, a pocket body installing supporting frame, a demountable anti-larceny cover and a current transformer. The utility model is characterized in that the door lock is an electronic digital lock, and the copper busbar telescoping connector connected with a copper bar behind the pocket body is formed by metal sheets through overlapping connecting. The electric meter arranged in the pocket body not only can record the practical power consumption output by the transformer and effectively prevent electricity theft, but also can realize the intellectualized management through a computer.
Description
Technical field
The utility model relates to a kind of electric metering box, in particular for the digital electricity-stealing prevention metering tank of the intelligent electronic of the total metering of substation transformer outlet electric power.
Background technology
Artificial now pernicious stealing electricity phenomenon is very serious, causes country and electric power enterprise to cause very big economic loss.According to investigations, the electricity filching means of electricity filching person, mostly being no table connects, electricity consumption before the table, the forgery lead sealing is opened the table lid and is dialled character code, falls anti-mutual inductor polarity, use the electrical burglary of remote control, light sensation etc., go into seriously its electricity filching means, all be nothing but to open electric energy metering box (cabinet), thereby reach the purpose that ammeter, mutual inductor are juggled things.The batch meter (cabinet) that electric system is at present used, sealing is generally all very poor, illegally opened easily, though the use that has special lead sealing or common electronic lock because the lead sealing transreplication, the ordinary electronic lock easily is decrypted, so anti-electricity-theft performance extreme difference.In addition, adopt hard copper ear or copper bar with the low pressure outlet that transformer low voltage outlet sleeve pipe is connected more, owing to expand with heat and contract with cold, often that transformer outlet capital is bad, cause leakage of oil.
China's utility model patent, the patent No. 99206254 discloses a kind of " anti-electricity-theft codified machinery control electric metering box ", this electric metering box is the line of electric force entrance hole that will be provided with on the batch meter backboard and be connected foot rest and covered by pilferproof closure, pilferproof closure is connected in casing with the casing backboard, the problem of stealing before preventing from effectively to show.But because metering casing door lock adopts mechanical type coding lock, as easy as rolling off a log be decrypted or the people for divulging a secret.
Summary of the invention
The utility model is to solve the problem that existing electric metering box adopts ordinary electronic lock, the anti-electricity-theft poor performance of mechanical code lock.
The utility model is achieved in that the digital electricity-stealing prevention metering tank of this intelligent electronic, by the metering casing, chamber door, door lock, the casing mounting bracket, removable pilferproof closure, the line of electric force binding post, ammeter mounting bracket in the casing, current transformer is formed, the bottom of casing backboard is provided with the line of electric force entrance hole, the casing mounting bracket is arranged on the outside of line of electric force entrance hole, pilferproof closure covers casing mounting bracket and line of electric force entrance hole, door lock adopts the electronic puzzle lock with memory function, and flexible the connecing by the electrically conductive elastic sheet metal is superimposed of the copper busbar that is connected with copper bar behind the case connects and composes.
The utility model is compared with existing electric metering box, has following outstanding advantage:
1, cipher random design, not for known to anyone, high safety.
2, can read batch meter by key at any time and be locked in information whenever, comprise time, the number of times that lock is unlocked at every turn and open key numbering etc., and by the computer realization intelligent management.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a front elevation of the present utility model.
Fig. 3 is the rear view after the utility model is pulled down pilferproof closure.
Fig. 4 is the flexible structural representation that connects of the utility model copper busbar.
Embodiment
Referring to Fig. 1-Fig. 4, the digital electricity-stealing prevention metering tank of this intelligent electronic, by metering casing (4), chamber door (2), door lock (3), casing mounting bracket (13), removable pilferproof closure (8), line of electric force binding post (6), ammeter mounting bracket (5) in the casing, current transformer (7) is formed, the bottom of casing backboard is provided with line of electric force entrance hole (12), casing mounting bracket (13) is arranged on the outside of line of electric force entrance hole (12), pilferproof closure (8) covers casing mounting bracket (13) and line of electric force entrance hole (12), door lock (3) adopts the electronic puzzle lock with memory function, simultaneously, for strengthening the overload capacity of electric current, preventing that copper bar from expanding with heat and contract with cold causes the transformer leakage of oil with transformer outlet capital is bad, and the copper busbar that is connected with copper bar behind the case is stretched and connect (14) and connect and compose by copper sheet is superimposed.In addition, because chamber door (2) is provided with observing window (9), for preventing stealing on the ammeter tie point, chamber door (2) medial surface is provided with the thief-proof plate washer of ammeter table pin (1).
Electronic puzzle lock can be divided into two parts: electronic section and mechanical part.The key of electronic section has a cover software administration, must on the read-write sign indicating number device that computer connects, be provided with before unblanking each time electron key, being provided with can be by management software to electron key effective time, effective degree is provided with, simultaneously can also write down the reason of unblanking, data such as unlocking person are set up the archives of each lock.It is unknown by the people that password between key and the lock is that computer is provided with at random, can not divulge a secret, and crypto chip has 2,800,000,000 kinds of combinations, never repeats, and really reaches thief-proof purpose.When unblanking the electron key that sets is aimed at the electron key hole (10) of lock, contact can be opened after the electronic section confirmation more than 0.3 second automatically, just can open anti-electricity-theft chamber door after opening mechanical part with mechanical key by mechanism's keyhole (11) again.Each key can also retaking of a year or grade when unblanking the first eight time in lock information of unblanking, can understand Box for avoiding fraudulent use of electricity by the deciphering of code reader and whether once illegally be entered, reach general management to lock, guaranteed the metering safety of electric power enterprise.
