Abstract
The utility model discloses an electric energy meter, in particular to an overload protection energy meter, including a circuit breaker and an energy meter. The circuit breaker is fixed on the soleplate of the energy meter and is positioned below the energy meter instrument and the circuit breaker is connected with the output circuit of the meter. The utility model has a small volume and is provided with overload protection function and simple structure and others.
Description
Technical field
The utility model relates to a kind of electric energy meter, especially relates to a kind of electric energy meter that possesses the overload protection ability, belongs to instrument field.
Background technology
Now common electric energy meter self can not reach the requirement of overload protection, and passing through of having when overload installed an air switch additional and come holding circuit safety, and this way takies very big space, but can not play the effect of an overload protection for ammeter self.This has become a problem that urgent need will solve.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, volume is little, have the overload protection electric energy meter that when overload can disconnecting circuit plays a protective role.
The electric energy meter of overload protection of the present utility model comprises isolating switch, electric energy meter, and described isolating switch is fixed on the electric energy meter base plate and is positioned at the below of electric energy meter instrument; Described isolating switch is connected on the output circuit of ammeter.
Described isolating switch can be an air switch.
Described fixing can be that the projection guide rail is arranged on the base plate of electric energy meter, and described isolating switch has the groove that cooperates with guide rail; Described fixing also can be by nut or screw isolating switch and electric energy meter base plate to be linked into an integrated entity.
Electric energy meter according to above-described overload protection has characteristics such as cost is low, easy for installation, volume is little.
Figure of description
Fig. 1 is a circuit working schematic diagram of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Embodiment
In the drawings; the electric energy meter of overload protection comprises isolating switch 1 and ammeter 2; described isolating switch 1 is fixed on the base plate of ammeter 2; isolating switch 1 is positioned at ammeter ends relative with instrument ammeter 2 base plates; the end face that isolating switch and ammeter base plate join is fluted; on ammeter 2 base plates projection is arranged, described projection can embed in the groove of isolating switch, thereby both are fixed together.
Claims (3)
