Abstract
The utility model relates to a shielding ammeter case mainly is applied to the surreptitiously electric field of hi -Tech that prevents, including the box, the box internal surface sets up first shielding magnetic field net, sets up the case lid on the box, first shielding magnetic field net earth connection, case inner surface of the cover sets up secondary shielding magnetic field net, secondary shielding magnetic field net earth connection. The utility model discloses simple structure, the simple installation, solved through plus the high -intensity magnetic field problem of stealing the electricity, materials are few, with low costs.
Description
Technical field
The utility model relates to a kind of shielding ammeter box, is mainly used in and prevents high-tech stealing field.
Background technology
For the present situation of current high-tech stealing, the motionless lead sealing of a lot of stealing users, need not open ammeter box, and the special stealing instrument that power utility check personnel are difficult to find carries out stealing.Mainly contain two kinds of methods, one is implement interference with strong magnet to ammeter, makes its not charging or few charging within a period of time, reaches the object of stealing; Two is the readings rewriting ammeter with special radio writing instrument, reaches the object of stealing.
For above problem, a kind of ammeter box is had to completely cut off field signal by arranging armoured magnetic field plate at present, avoid illegal user by additional high-intensity magnetic field stealing, solve additional high-intensity magnetic field stealing problem like this, but armoured magnetic field plate consume material is many, cause cost too high, cause waste, bring difficulty to all-round popularization.
Utility model content
The purpose of this utility model is to provide a kind of shielding ammeter box, and structure is simple, and simple installation, solve the problem by additional high-intensity magnetic field stealing, materials are few, and cost is low.
Shielding ammeter box described in the utility model, comprises casing, and interior arranges the first armoured magnetic field net, and casing arranges case lid, the first armoured magnetic field net ground wire; Case lid inside surface arranges secondary shielding magnetic field net, secondary shielding magnetic field net ground wire.
Described shielding ammeter box, ammeter is installed in casing, covers the magnetic line of force, solve the problem by additional high-intensity magnetic field stealing around ammeter by the first armoured magnetic field net and secondary shielding magnetic field screen; By adopting the first armoured magnetic field net and secondary shielding magnetic field net, decreasing materials, providing cost savings.
The first described armoured magnetic field net and/or secondary shielding magnetic field net are brass wire shielding magnetic field net.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model structure is simple, covers the magnetic line of force, solve the problem by additional high-intensity magnetic field stealing by the first armoured magnetic field net and secondary shielding magnetic field screen;
(2) first armoured magnetic field nets and secondary shielding magnetic field net are designed to netted, can either meet the requirement of armoured magnetic field signal, save materials simultaneously, provided cost savings;
(3) first armoured magnetic field nets and secondary shielding magnetic field net respectively ground wire, effectively prevent the first armoured magnetic field net and secondary shielding magnetic field guipure electricity is hurted sb.'s feelings, effective guarantee use safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1.
In figure: 1, casing 2, first armoured magnetic field net 3, ammeter 4, secondary shielding magnetic field net 5, case lid.
Embodiment
Below in conjunction with embodiment, the utility model is described further:
As shown in Figure 1, shielding ammeter box described in the utility model, comprises casing 1, and casing 1 inside surface arranges the first armoured magnetic field net 2, casing 1 is arranged case lid 5, the first armoured magnetic field net 2 ground wire; Case lid 5 inside surface arranges secondary shielding magnetic field net 4, secondary shielding magnetic field net 4 ground wire.First armoured magnetic field net 2 and/or secondary shielding magnetic field net 4 can be brass wire shielding magnetic field net.
Principle of work:
Described shielding ammeter box, ammeter 3 is installed in casing 1, shields the magnetic line of force, solve the problem by additional high-intensity magnetic field stealing around ammeter 3 by the first armoured magnetic field net 2 and secondary shielding magnetic field net 4; By adopting the first armoured magnetic field net 2 and secondary shielding magnetic field net 4, decreasing materials, providing cost savings, be conducive to popularizing in an all-round way.
Shield the magnetic line of force by the first armoured magnetic field net 2 and secondary shielding magnetic field net 4, the requirement of armoured magnetic field signal can either be met, solve the problem by additional high-intensity magnetic field stealing; Save materials simultaneously, provided cost savings; First armoured magnetic field net 2 and secondary shielding magnetic field net 4 be ground wire respectively, effectively prevent the first armoured magnetic field net 2 and secondary shielding magnetic field net 4 is charged hurts sb.'s feelings, effective guarantee use safety.
Claims (2)
1. a shielding ammeter box, it is characterized in that, comprise casing (1), casing (1) inside surface arranges the first armoured magnetic field net (2), casing (1) is arranged case lid (5), the first armoured magnetic field net (2) ground wire; Case lid (5) inside surface arranges secondary shielding magnetic field net (4), secondary shielding magnetic field net (4) ground wire.
