Description
[technical field]
The utility model relates to electric energy meter, relates in particular to single-phase electric energy meter.
[background technology]
Electric energy meter is important electric energy metrical product, it is widely used in the every field of national economy such as industrial and agricultural production, national defence, metallurgy, electric power, traffic, urban construction, relates to health of human body, property safety and national economy is played the industrial products of material impact.Electric energy meter is national interests and the indispensable equilibrium point of individual economic interests as a kind of special commodity, and is closely bound up with the electricity consumption policy of country and the people's life.Electric energy meter divides two kinds of mechanical type and electronic types.
The principle of work of mechanical power energy meter is: when electric energy meter is inserted circuit-under-test, just have exchange current to flow through in current coil and the potential winding, these two exchange current produce the magnetic flux of alternation respectively in their iron core; Alternating flux is passed the aluminium dish, induces eddy current in the aluminium dish; Eddy current is subjected to the effect of power again in magnetic field, thereby makes the aluminium dish obtain the initiatively i.e. moment and rotating of torque.The power of load consumption is big more, and is big more by the electric current of current coil, and the eddy current that induces in the aluminium dish is also big more, and the moment that the aluminium dish is rotated is just big more.The size that is torque follows the power of load consumption to be directly proportional.Power is big more, and torque is also big more, and the aluminium dish rotates also just fast more.When the aluminium dish rotates, be subjected to the effect of the braking moment of permanent magnet generation again, braking moment is with initiatively the moment direction is opposite; The size of braking moment is directly proportional with the rotating speed of aluminium dish, and the aluminium dish rotates soon more, and braking moment is also big more.When active moment and braking moment reached transient equilibrium, the aluminium dish was with uniform rotation.The electric energy that load consumed is directly proportional with the revolution of aluminium dish.When the aluminium dish rotates, drive counter, the electric energy that is consumed is indicated.The simple procedure of electric energy meter work that Here it is.
The principle of work of electronic electric energy meter is: electronic electric energy meter is called solid-state electric energy meter again, and present most of advanced persons' electronic electric energy meter all adopts the mixed signal structure, and front end uses high-precision a/d converter, and uses DSP in the rear end.Some ammeters use discrete components, and are most then adopt specialized designs to be used for the ASIC of electric energy metrical, and this mixed signal structure has high precision and long-time stability.Before to electric current and voltage sampling, these two kinds of signals all need to carry out conversion to reach the appropriate signal level, and all electric energy meters all have the voltage and current sensing element.Wherein induction by current is comparatively difficult, because current inductor needs the range of dynamic measurement of a broad, and owing in current waveform, contain a plurality of harmonic components, so also want to handle wider frequency range.Along with the continuous growth of home-use electric weight, Super-Current Measurement will be not limited only in the commercial Application, and as the maximum energy measurement 200A of the new electric energy meter of installing of U.S.'s dwelling house electric current, present induction by current technology can not have been measured so big electric current cost-effectively.Having three kinds of induction technologies the most commonly used at present, is respectively small resistor current bypass, current transformer and hall effect sensor.
The kind of electronic electric energy meter is a lot, and polytypes such as single-phase, three-phase, multi-functional, GPRS are arranged.Wherein the mode of connection of single-phase electric energy meter has two kinds of 1,2 wiring and 1,4 wiring, the position of shunt on base is different in these two kinds of different modes of connection, usually, at the different modes of connection, need to make different terminal box or base, this just needs two pairs of moulds just can meet the different needs, like this, the utilization factor of mould is the end of than, and the cost of manufacture of product is higher.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of electric energy meter that has the commutation seat, makes two kinds of different modes of connection of 1,2 wiring and 1,4 wiring can use identical base.
For achieving the above object, the utility model proposes a kind of electric energy meter that has the commutation seat, include but not limited to base, shunt, brace, described shunt and brace are installed in the base, also comprise the commutation seat, described commutation seat comprises some grooves, and after the commutation seat was installed in the base, shunt was limited in the groove of commutation seat.
As preferably, also comprise gathering sill on the described base, the shape of described gathering sill is identical with the shape of commutation seat, and the installation site of commutation seat is limited.
As preferably, also comprise buckle on the described base, described buckle blocks the part corner of gathering sill, and gathering sill must not be moved or come off.
The beneficial effects of the utility model: the utility model increases an independently commutation seat in the structure of original electric energy meter, like this, shunt adopts two kinds of different modes of connection of 1,2 wiring and 1,4 wiring also can use identical base, do not need to make different terminal boxs or base, only need one pair of mould just can meet the different needs; Simultaneously, according to 1,2 wiring and 1, the position difference of shunt in 4 wiring, structure to the commutation seat is carried out ingenious design, 1, the seat forward that will commutate during 2 wiring is placed the position that groove on the commutation seat just can limit shunt and brace just, 1, to commutate during 4 wiring and place behind the seat Rotate 180 °, groove on the commutation seat just can limit shunt and brace at another correct position again just, though like this 1,2 wiring and 1, the position difference of shunt and brace in 4 wiring, but be to use identical commutation seat just can fix the shunt and the brace of these two kinds of diverse locations, only ° placement of commutation seat Rotate 180 just can need be realized; Simultaneously, the commutation seat of being made by insulating material can also separate live wire with zero line, high low-voltage is isolated.The installation direction that the utility model changes the commutation seat just can adapt to fixing of shunt in two kinds of different modes of connection, terminal box or base then are identical, with respect to traditional method for designing, this design concept is ingenious, make structure compact more, and the cost of manufacture of commutation seat is much lower than terminal box or base, and the utilization factor of mould is improved, and greatly reduces the cost of manufacture of product.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
