Problems solved by technology

However, as a practical engineering application, there are still defects, because the low-voltage power distribution system is a project with a huge base. This separate design requires that the controller has the same number of ports as the users in the meter box to connect to the corresponding user's electric meter. Assuming that the meter There are 24 electric meters in the box, so 24 power lines need to be connected between the controller and each electric meter, which brings great inconvenience to the site construction, and is easy to make mistakes and cause accidents, which also increases the cost

Embodiment Construction

[0008] see Figure II , the smart meter is equipped with a strobe relay (the controller does not need to set a strobe circuit), one end of the normally open point of the strobe relay is connected to the common end of the three phase-selection magnetic latching relays of the user ammeter, and the other end is output to the outside of the meter to switch with the controller The common wire of the circuit is connected.

[0009] The system composition in the table box is as follows: Figure three As shown, assuming that No. 1 ammeter needs to switch from phase A to B, and No. n ammeter needs to switch from B phase to C phase. The specific working process is as follows: 1. The controller issues an instruction to close the strobe relay of No. 1 ammeter, In this way, the common end of the magnetic latching relay of the No. 1 ammeter is connected with the common end of the switching circuit of the controller, which meets the condition of continuous power commutation. At the same tim...

Abstract

The invention provides an intelligent electric meter capable of active power distribution. The intelligent electric meter is characterized in that the electric meter is provided with a gating switch,and cooperates with a phase changing circuit of a controller to achieve the active power distribution. The intelligent electric meter provided by the invention has the positive effects that the construction complexity and the cost can be reduced.

Description

technical field [0001] The invention designs an intelligent single-phase electric meter forming an active distribution network, which belongs to the field of electric equipment. Background technique [0002] The current distribution network mainly takes out single-phase power from the three-phase output end of the three-phase distribution transformer to supply power to users. This low-voltage power distribution has been fixed and installed during construction and cannot be changed casually. With the increase of high-power single-phase electrical appliances and the randomness of power consumption, the fixed low-voltage distribution network cannot adapt to the needs of variable loads. Therefore, it is necessary to establish a low-voltage active distribution network that can adjust the topology at any time. In the invention application with the application number 201410078122.2, the problem of uninterruptible power distribution network structure adjustment has been solved. In t...
