Abstract
The utility model discloses a power supply device for an electric energy meter. The power supply device comprises a transformer and a power supply module which are welded on a PCB (Printed Circuit Board) and are in electric connection with each other, wherein the transformer is a 41 iron-core transformer (1). In the power supply device provided by the utility model, as the transformer is the 41 iron-core transformer with a wider range of working voltage, the power supply device has a wider range of working voltage, and further, the electric energy meter adopting the power supply device has wide application range and high operational reliability.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of supply unit that is used for electric energy meter.
Background technology
The supply unit of prior art electric energy meter comprises transformer and the power module that is welded on the pcb board and is electrically connected, and described transformer is that capacity is 35 appendiron core transformers of 2W, and described power module is the common power module.There is following defective in the supply unit that said structure is used for electric energy meter in the use of reality: because the working power scope of 35 appendiron core transformers that adopt is narrower, thereby cause the operating voltage range of supply unit of prior art electric energy meter narrower, thereby make that the scope of application of prior art electric energy meter is little and functional reliability is low.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of operating voltage range the wide supply unit that is used for electric energy meter.
The technical solution of the utility model is, a kind of supply unit that is used for electric energy meter is provided, and comprises the transformer and the power module that are welded on the pcb board and are electrically connected, and described transformer is 41 appendiron core transformers.
After adopting above structure, the utility model compared with prior art has the following advantages:
The transformer that supply unit adopted that the utility model is used for electric energy meter is 41 appendiron core transformers, the operating voltage range broad of this transformer, thereby make the operating voltage range broad of supply unit of the utility model electric energy meter, and then make that the applied widely and functional reliability of the utility model electric energy meter is high.
As improvement, described power module is the wide region switch power module, because this wide region switch power module has efficient height, advantage that the working power scope is wide, therefore make the operating voltage range of supply unit of the utility model electric energy meter further widen, and then make that the scope of application of the utility model electric energy meter is wider and functional reliability is higher.
Description of drawings
Accompanying drawing is the structural representation that the utility model is used for the supply unit of electric energy meter.
1,41 appendiron core transformers shown in the figure, 2, the wide region switch power module.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, a kind of supply unit that is used for electric energy meter of the utility model, comprise the transformer and the power module that are welded on the pcb board and are electrically connected, described transformer is 41 appendiron core transformers 1, promptly is the commercially available EI41 sections core transformer that we are familiar with.
Described power module is a wide region switch power module 2, as the wide region switch power module of Dalian Tai Si Man production.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
Claims (2)
1. a supply unit that is used for electric energy meter comprises the transformer and the power module that are welded on the pcb board and are electrically connected, it is characterized in that: described transformer is 41 appendiron core transformers (1).
