Abstract
The utility model discloses a relay with manganin, which comprises a manganin diverter and current sampling signal lines, wherein sampling terminals are arranged on the manganin diverter, and are symmetrically arranged on the two sides of the center of the manganin diverter, and input ends of the current sampling signal lines are fixedly connected with the sampling terminals in a welding manner. According to the relay, the existing relay with the manganin is designed and improved, and a current sampling signal is output in the middle of the manganin diverter in a manganin center current signal sampling mode, so that interference of scrambled alternating magnetic fields in a surrounding environment with a manganin sampling signal can be prevented; a metering performance index of a meter in electric energy meter application can be increased greatly; for a power company, a risk of electricity stealing by a user can be reduced; and the safety of state property can be ensured.
Description
Technical field
The utility model relates to a kind of electric energy meter device, relates in particular to a kind of relay with copper-manganese.
Background technology
At present, the relay with copper-manganese that uses of existing most single-phase electric energy meter on the market, all special adaptations is not done in the impact of alternating magnetic field, when other users' large ampere wires passes through non-loaded user, the magnetic field that induces because of large electric current can cause non-loaded user to have good luck, although therefore former thereby the comparision of quantity of electricity of having good luck that cause is little, also can cause unnecessary controversial issue in the course of time.
The utility model content
The purpose of this utility model is to provide a kind of relay with copper-manganese that prevents that alternating magnetic field from disturbing.
The relay with copper-manganese that the utility model provides, comprise manganese copper diverter and current sampling signal line, be provided with sampling terminal on described manganese copper diverter, the both sides, center that are arranged in described manganese copper diverter of described sampling terminal symmetry, the input of described current sampling signal line is fixedly connected on described sampling terminal by the form of welding.
The output of described current sampling signal line connects by a solder plug.
Described solder plug adopts two core modular connections.
The utility model is by carrying out design improvement to existing relay with copper-manganese, by adopting the mode of copper-manganese center current signal sampling, in manganese copper diverter mid point output current sampled signal, can prevent that not only alternating magnetic field mixed and disorderly in surrounding environment from producing interference to the copper-manganese sampled signal, can also significantly promote the metering performance index of table meter in electric energy meter is used, and for Utilities Electric Co., more can reduce the risk of user's stealing, guarantee the safety of national wealth.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As can be seen from Figure 1, this relay with copper-manganese of the utility model, comprise manganese copper diverter 1 and two current sampling signal lines 2, in the manganese copper diverter 1 monosymmetric punching in center, two sampling terminals 3 are arranged, the input of each current sampling signal line 2 is fixedly connected on corresponding sampling terminal 3 by the form of welding, and the output of current sampling signal line 2 connects by the solder plug 4 of two core standards.
Under equivalent environment, the utility model and prior art are carried out following concrete test:
Test one: when externally disturbing with the 60A electric current
The current value that induces on ammeter of the present utility model belongs to below shunt running point less than 15mA, and the metering of his-and-hers watches meter is without impact; The current value that induces on the ammeter of prior art can reach 40mA, also can reach 100mA during the multi-turn test, exceeds the starting standard of electric energy meter, may cause table meter error count amount.
Test two: under the interference environment of 0.5mT
The measuring accuracy of the utility model 5A test point is in ± 0.4%, and the measuring accuracy of prior art 5A test point is in ± 2.5% left and right.
Test three: when power transformer not being calibrated in metering circuit
The impact that sampling produces on the utility model is in 0.05% left and right, and the impact that sampling produces on prior art is in 1% left and right.
This shows, compared with prior art, the utility model is extremely insensitive on the impact of the alternating magnetic field in surrounding environment, disturbs and is effectively offset, and his-and-hers watches meter metering performance index improves.
