Description
Technical field
The present invention relates to a kind of electric energy meter, particularly a kind of electricity stealing prevention device for electric energy meter that can effectively stop electricity filching behavior.
Background technology
At present, some lawless persons bore that electric power is installed, managerial leak, deliberately change phase place, the voltage of electric energy meter measurement loop, the mode of connection of electric current, change the properity of electric energy meter itself, without restraint carry out stealing, thereby make power supply department and national resources, property cause heavy losses.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, can prevent by the electricity stealing prevention device for electric energy meter of stealing and provide a kind of.
A kind of electricity stealing prevention device for electric energy meter, it is characterized in that: include magnet-sensitive switch, magnetic sheet, slip insulating polar pole, start-stop post, coded lock, back-moving spring and binding post, magnetic sheet is arranged near of magnet-sensitive switch two contacts, and relatively magnet-sensitive switch do away from or close linear reciprocating motion, magnetic sheet is connected with slip insulating polar pole, slip insulating polar pole earthing prefastening force spring inserts in binding post and the terminal that can connect does linear reciprocating motion, described prefastening force spring is pressed in the magnetic sheet being connected with slip insulating polar pole can allow the position of magnet-sensitive switch two contact point adhesives, a side at slip insulating polar pole is provided with a groove, slide during in release conditions by the compacted groove side that is arranged at slip insulating polar pole of the start-stop post of coded lock control and at prefastening force spring on the traffic direction of insulating polar pole, two contacts of described magnet-sensitive switch are connected with two contacts of binding post conducting strip respectively, described conducting strip stage casing forms the middle nonconducting structure of two ends conduction for being made up of insulating material.
The electricity stealing prevention device for electric energy meter of this structure, because magnet-sensitive switch is a kind of special key, be made up of special material its two contacts, is encapsulated in the glass tube of vacuum.As long as approach it with magnet, two contacts will be pulled together, and make circuit turn-on.Therefore the present invention utilizes this feature of magnet-sensitive switch, magnet-sensitive switch is incorporated in anti-electricity-theft device, and magnetic sheet is set near magnet-sensitive switch, utilize magnetic sheet control the suction of magnet-sensitive switch and close, and magnetic sheet passes through structure simply cleverly, be connected with slip insulating polar pole by magnetic sheet, slip insulating polar pole is pressed in binding post by preloading spring, once having people's stealing transfers to input power live wire from ammeter terminal, at this moment slide insulating polar pole because the effect of preloading spring is moved immediately, make insulating polar pole drive magnetic sheet away from magnet-sensitive switch, thereby make two contact separation of magnet-sensitive switch, input end live wire is disconnected, thereby reach the function of cutting off input live wire, in insulating polar pole action, slip in groove that time that start-stop post matches with it at the groove of insulating polar pole, due to the effect of coded lock, start-stop post is by locked slip insulating polar pole, make it to reset, cut off power supply thereby realize, to play anti-electricity-theft object.As need restore electricity, after must having power supply department personnel that the password setting is opened, make the slip insulation utmost point make it near magnet-sensitive switch magnetic sheet jack-up thereby the insulating polar pole that makes to slide resets and power firestreak is accessed to binding post, make contact action closure recover normally work.
Described magnet-sensitive switch is tongue tube.
Described magnetic sheet is ndfeb disk.It has little, the lightweight feature of volume, is a kind of artificial permanent magnet, is to have up to now the permanent magnet of strong magnetic force.
Described binding post or can directly utilize the binding post of former electric energy meter to reequip it, is divided into two by former firewire binding post conductive metal sheet, separates with bakelite insulating material in centre.Can certainly directly replace original binding post with new binding post, new binding post is that its conductive metal sheet is that two sections are the sheet metal of conduction, and stage casing is the insulating segment that insulating material forms.
Described coded lock is the coded lock of three bit digital.
In sum, the present invention's following advantage compared to existing technology:
This electricity stealing prevention device for electric energy meter, reasonable in design, easy to use, safe and reliable, once have people's stealing, the module for anti-fraudulent cut-out input power of working immediately, the loop of cutting off the electricity supply, overcome a unsolved difficult problem for a long time, effectively stoped electricity filching behavior.It can directly add this device in new electric energy meter, also can reequip existing old electric energy meter, and also very simple and convenient of repacking, only need reequip the conducting strip of former connection box of electric energy meter post, therefore very applicable.

Embodiment
Below in conjunction with embodiment, the present invention is described in more detail.
An electricity stealing prevention device for electric energy meter as shown in Fig. 1-6, comprises a 16A tongue tube 1, ndfeb disk 2, slip insulating polar pole 3, start-stop post 4, three bit digital coded locks 5, preloading spring 6 and an electricity stealing prevention device for electric energy meter of binding post 7 common compositions.Ndfeb disk is arranged near of tongue tube two contacts, and relatively tongue tube do away from or close linear reciprocating motion, magnetic sheet is connected with slip insulating polar pole, slip insulating polar pole earthing prefastening force spring inserts in binding post and the terminal that can connect does linear reciprocating motion, described prefastening force spring is pressed in the magnetic sheet being connected with slip insulating polar pole can allow the position of tongue tube two contact point adhesives, a side at slip insulating polar pole is provided with a groove, slide during in release conditions by the compacted groove side that is arranged at slip insulating polar pole of the start-stop post of coded lock control and at prefastening force spring on the traffic direction of insulating polar pole, two contacts of described tongue tube are connected with two contacts of binding post conducting strip 9 respectively, described conducting strip stage casing is to be formed and formed the middle nonconducting structure of two ends conduction by insulating material-bakelite insulator 10.
In normal situation, tongue tube is the contact of one group of closure, and contact 1,2 is static closed, normal power supply, wire 8 withstands slip insulating polar pole 3, makes ndfeb disk 2 approach 16A tongue tube 1, tongue tube contact 1,2 closures, connect input circuit, make electric energy meter in normal operating conditions.Once having people's stealing extracts input power live wire from ammeter terminal, at this moment anti-electricity-theft slip insulating polar pole 3 is because the effect of preloading spring 6 is moved immediately, start-stop post 4 slides in groove, make ndfeb disk 2 leave 16A tongue tube 1, now the back contact 1,2 of tongue tube is opened, input end live wire is disconnected, thereby reach the function of cutting off input live wire.At this moment due to the effect of three bit digital coded locks 5, start-stop post 4, by locked slip insulating polar pole 3, makes it to reset, and realizes and cuts off power supply, plays so anti-electricity-theft object.As need restore electricity, after only having power supply department personnel to open with the password setting, slip insulating polar pole 3 could reset, and again access wire 8, slip insulating polar pole 3 after reset, by ndfeb disk 2 jack-up, near 16A tongue tube 1, moves tongue tube 1, contact 1,2 closures, the closed rear normal work that recovers.
It is same as the prior art that the present embodiment is not stated part.
