Abstract
The invention discloses a kind of single-phase electronic energy meter galvanic element structure, including relay (1), transformer (2), preceding conducting strip (3), rear conducting strip (4) and flexible conductor (5), the preceding conducting strip (3) is welded through (2) after transformer and one end of flexible conductor (5), and one of current sheet of the other end of flexible conductor (5) and relay (1) welds, another current sheet and the rear conducting strip (4) of the relay (1) are welded.Each conductive component of the present invention is attached by welding manner, and can effectively reduce caloric value using transformer, is effectively reduced the thermal runaway probability of electric energy meter, is drastically increased reliability.
Description
Technical field
The present invention relates to a kind of electric energy meter component structural, more particularly to a kind of structure of electric energy meter internal current part.
Background technology
Electric energy meter is the instrument for measuring electric energy, also known as kilowatt-hour meter, energy meter, kilowatt-hour table, refers to the various electricity of measurement
The instrument of amount.The galvanic element of traditional single-phase electronic energy meter uses mode connects for screw using current divider and conducting strip, is fully loaded with
Caloric value is big during excessively stream, exists and burns risk.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of single-phase electricity of high reliability
Minor electric energy meter current modular construction.
Technical scheme：To achieve the above object, the technical solution adopted by the present invention is：
A kind of single-phase electronic energy meter galvanic element structure, including relay, transformer, preceding conducting strip, rear conducting strip
And flexible conductor, the preceding conducting strip are welded after passing through transformer with one end of flexible conductor, and the other end of flexible conductor with
One of current sheet welding of relay, another current sheet and the rear conducting strip of the relay are welded.
Preferably：The preceding conducting strip and rear conducting strip are Z-shaped.
Preferably：The transformer, rear conducting strip are respectively arranged at the both sides of relay.
The present invention compared with prior art, has the advantages that：
The single-phase electronic energy meter galvanic element structure of the present invention, each conductive component are attached by welding manner,
And caloric value can be effectively reduced using transformer, the thermal runaway probability of electric energy meter is effectively reduced, drastically increases reliability.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein, 1 relay is represented, 2 represent transformer, and conducting strip before 3 expressions, conducting strip after 4 expressions, 5 represent flexible conductors.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these examples are merely to illustrate this
Invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are various to the present invention's
The modification of the equivalent form of value falls within the application appended claims limited range.
A kind of single-phase electronic energy meter galvanic element structure, as shown in figure 1, including relay 1, transformer 2, preceding conduction
Piece 3, rear conducting strip 4 and flexible conductor 5, the preceding conducting strip 3 pass through after transformer 2 to be welded with one end of flexible conductor 5, and
The other end of flexible conductor 5 welds with one of current sheet of relay 1, another current sheet of the relay 1 and rear conduction
The complete single-phase electronic energy meter galvanic element of shape one after piece 4 is welded.The preceding conducting strip 3 and rear conducting strip 4 are equal
To be Z-shaped.The transformer 2, rear conducting strip 4 are respectively arranged at the both sides of relay 1.
The current divider of existing electric energy meter is actual be exactly a resistance sincereness very little resistance, because its is cheap, mesh
Preceding single-phase electric meter generally uses, and when meter case is designed as narrow volume, the heating of current divider just becomes extremely important
, because amount of heat caused by current divider can not be dissipated by the shell of narrow volume, ultimately result in current-carrying in ammeter
Part temperature rise is too high so as to cause insulated support not bear, and internal short-circuit can be caused to trigger electrical fire when serious, and originally
The galvanic element of the single-phase electronic energy meter of invention uses transformer, while each conductive component takes welding manner to complete
Connect, and transformer 2, rear conducting strip 4 are separately positioned on to the both sides of relay 1, found through temperature rise test comparing result, application
The structure of the present invention can effectively reduce preceding conducting strip 3 and rear more than the surface temperature rise 10K of conducting strip 4, so as to effectively reduce electric energy
The thermal runaway probability of table, drastically increases reliability.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
