Abstract
The utility model is designed to provide an electricity metering box for intelligent anti-theft by which electric power is shut off automatically and is not transmitted automatically once the metering box door is opened without permission, including a grid power supply box and a user power supply box connected together, a brake type switch and a meter arranged inside the grid power supply box and an air switch inside the user power supply box. The grid power supply box is also provided with an air switch with excitation release and an intelligent controller connected with the air switch with the air switch with excitation release through signal line. The entering line end of the air switch with excitation release is connected with the output end of the brake type switch through wires, the outgoing line end of the air switch with excitation release is connected with the entering line end of the air switch through wires and the power wire of the intelligent controller is connected with the entering line end of the brake type switch. As the intelligent controller is adopted in the utility model, the effects of anti-theft electricity consumption and eliminating electricity consumption based on violating the regulations are cleverly reached. The utility model is mainly applicable to the electric power departments.
Description
Technical field
The utility model relates to the equipment that a kind of electric industry department is used for electric-power metering, specifically, relates to a kind of antitheft power consumption metering box.
Background technology
In recent years, the equipment that electric industry department is used for electric-power metering takes place often to be opened privately, and is changed the thing of metering outfit privately, cause the heavy economic losses of electric industry department thus, even the frequent generation that electric shock causes people's casualty accident occurs, cause very bad influence to society.Cause the generation of people's casualty accident for fear of economic loss and electric shock, electric industry department tries every possible means and stops this type of thing appearance, various antitheft electricity consumption metering outfits have successively been made, but produce little effect, analyze reason, be that mainly the batch meter chamber door is opened after, the user can freely send electricity and outage, even can change the attribute or the coefficient of gauging table privately, make electric industry department suffer economic loss.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, in case a kind of intelligent anti-theft power consumption metering box that the batch meter chamber door just cuts off the power supply automatically and can't send electricity voluntarily of opening privately is provided.
Goal of the invention of the present utility model is to realize by following technical scheme:
A kind of antitheft power consumption metering box, comprise the mains supply case and the user power utilization case that link together, be arranged on the disconnecting link formula switch 1 and the gauging table 2 of mains supply case the inside and the air switch 4 that is arranged on user power utilization case the inside, be provided with the air switch 5 and the intelligent controller 6 that is connected with air switch 5 by signal wire that has the excitation dropout in mains supply case the inside, described air switch 5 ends of incoming cables connect disconnecting link formula switch 1 leading-out terminal by lead, air switch 5 leading-out terminals connect air switch 4 ends of incoming cables by lead, and described intelligent controller power lead connects the end of incoming cables of disconnecting link formula switch 1;
Be provided with the lead interlayer in mains supply case the inside, signal wire, lead and intelligent controller power lead are arranged on lead interlayer the inside;
On mains supply case chamber door and user power utilization case chamber door, be respectively arranged with locking device;
Described intelligent controller comprises the chamber door turn on sensor, verification key hole, power supply, control circuit, voicefrequency circuit and delay circuit reset.
The utility model has substantive distinguishing features and progressive with respect to prior art, specifically, following beneficial effect is arranged: 1, adopt intelligent controller, make illegal electric consumer in case open the batch meter chamber door privately, intelligent controller just can make the air switch that has the excitation dropout cut off the power supply automatically, and under the resetting of the electron key that does not obtain legal user or guardian, the air switch that has the excitation dropout can't send electricity, and illegal user can't send especially voluntarily; Simultaneously, in a single day this intelligent controller finds that illegal user opens chamber door, can in time report to the police; 2, this batch meter structural design is novel unique, compact, and good looking appearance, inside is provided with the lead interlayer, good concealment, preventing destructing performance is good; 3, during operation, the intelligent controller power consumption is extremely low.

Embodiment
For advantage of the present utility model and technical characterictic further are described, provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of antitheft power consumption metering box, comprise the mains supply case and the user power utilization case that link together, be arranged on the disconnecting link formula switch 1 and the gauging table 2 of mains supply case the inside and the air switch 4 that is arranged on user power utilization case the inside, be provided with the air switch 5 and the intelligent controller 6 that is connected with air switch 5 by signal wire that has the excitation dropout in mains supply case the inside, described air switch 5 ends of incoming cables connect disconnecting link formula switch 1 leading-out terminal by lead, air switch 5 leading-out terminals connect air switch 4 ends of incoming cables by lead, and described intelligent controller power lead connects the end of incoming cables of disconnecting link formula switch 1; Disconnecting link formula switch 1 inlet wire termination power supply grid, air switch 4 outlet termination consumer networks, gauging table 2 connects current transformers 3, current transformer 3 be installed between disconnecting link formula switch 1 and the air switch 5 the lead outside all around.
Be provided with the lead interlayer in mains supply case the inside, signal wire, lead and intelligent controller power lead are arranged on lead interlayer the inside, reach with this and to prevent that illegal electric consumer or transgression for using electricity person from revising the box house circuit without authorization, causes the damage grid equipment, even cause personal injury;
On mains supply case chamber door and user power utilization case chamber door, be respectively arranged with locking device, according to circumstances adopt general lockset to get final product;
As shown in Figure 2, described intelligent controller comprises the chamber door turn on sensor, verification key hole, power supply, control circuit, voicefrequency circuit and delay circuit reset; The chamber door turn on sensor self has memory function, adopts the electromagnet that has the electromagnetism locking mechanism usually; Control circuit adopts PLC or single-chip microcomputer; The verification key hole that resets can carry out the multidigit arranging and encoding according to actual needs, and the verification key forms one to one or the relation of one-to-many with resetting; Voicefrequency circuit sends caution sound when chamber door is just opened, but resetting of the verification key that do not obtain resetting in official hour will be sent alarm sound always.Intelligent controller is provided with five light emitting diodes, is used for showing the duty of primary power, air switch 5, audio alarm, password and check reset respectively, and light emitting diode makes system state clear, is convenient to management.
As shown in Figure 3, each stitch of the verification key that resets and each stitch of verification key hole that resets shown in Figure 2 mate mutually, and this each stitch of verification key that resets all is serially connected with diode, have anti-test, preventing decryption function.
