Abstract
The utility model relates to an electric energy metering device which comprises a transition plate, wherein a connecting terminal row and at least an electric energy metering unit are installed on the transition plate, each electric energy metering unit is provided with a live wire lead-in terminal, a zero wire lead-in terminal and a live wire lead-out terminal, the zero wire lead-in terminals of the electric energy metering units are respectively connected with the corresponding connecting terminals on the connecting terminal row, and the connecting terminals are connected together through short-circuit mode. The electric energy metering device is used to resolve the problems that the existing electric energy meters have many wiring points, the installing workload is large and the electric energy meters are burned because of loose wiring.
Description
Technical field
The utility model relates to a kind of electric power meter, belongs to the electrical instrumentation technical field.
Background technology
Present electric power meter comprises the table case and is located at some interior electric energy meters of table case, because this electric energy meter all adopts metering and shows incorporate structure, the external form of electric energy meter is bigger, so each electric energy meter can only be installed in it in table case independently by three screws, and each electric energy meter all has two input terminals and two outlet terminals (comprising live wire and zero terminal), in installation process wiring count more, cause installation workload big, install loaded down with trivial details, wiring faults hidden danger is more, particularly when load current is big,, also can cause the problem of burning table because some connection terminal wiring are insecure.
The utility model content
The purpose of this utility model provides the electric power meter that wiring is counted less in a kind of installation process, installation workload is little, uses the problem that existing connection box of electric energy meter point is many, installation workload big and cause the burning table because of wiring is insecure that solves.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric power meter, this device comprises rebound, connecting terminal block and at least one electric energy meter metering units are installed on the described rebound, described each electric energy meter metering units is provided with live wire input terminal and zero line input terminal and live wire outlet terminal, the zero line input terminal of described each electric energy meter metering units respectively with described connecting terminal block on corresponding connection terminal connect and described connection terminal short circuit together.
The live wire input terminal of described each electric energy meter metering units or live wire outlet terminal are connected with a disconnector.
Described each electric energy meter metering units is provided with draw-in groove and supporting elasticity bayonet lock, also is provided with guide rail on the described rebound, and described electric energy meter metering units is installed on the guide rail.
This electric power meter also comprises the table case, and described rebound is installed in the table case.
The beneficial effects of the utility model are: because the zero line of electric energy meter metering units described in the utility model is all received on the corresponding connection terminal of connecting terminal block on the rebound and these connection terminal short circuits together, make the zero line that is linked into the electric energy meter measuring apparatus only need one, irrelevant with the number of electric energy meter metering units in the table case, compare with existing electric power meter, the number of contacts that zero line is installed significantly reduces, installation workload is little, the unstable hidden danger of wiring is also little in the installation process, has significantly reduced the burning table probability that causes because of wiring is insecure.
The disconnector of the supporting connection of each electric energy meter metering units has played the effect of protection electric energy metrical unit.
Specific volume is little mutually with existing electric energy meter because of each electric energy meter metering units again, and light weight can snap fit onto on the guide rail, reduces the workload of installing, and can expand easily according to number of users.
