Cost control intelligent ammeter convenient to be mounted and dismounted

Abstract

The invention discloses a cost control intelligent ammeter convenient to be mounted and dismounted. The cost control intelligent ammeter is provided with a housing and an internal circuit, the housing is provided with a carrier wave upper cover, a wave carrier button difficult to drop, an embedded type seal and a detachable auxiliary wiring terminal, wherein the housing is made of a flame-retardant insulation material, the internal circuit is provided with a sampling module, a metering module, a microprocessor module, a display module, an indication module, a trip-out power-off module, an ESAM module, a multi-rate metering module, a communication module and an energy storage module, and after the shaft end of the wave carrier is disengaged from an original fixation position, the button does not drop from the wave carrier upper cover. Besides, simple sealing of the housing of the ammeter is realized, wiring of wiring terminals is facilitated, the materials of binding post copper bars are reduced, and the production cost of the ammeter is decreased.

Description

technical field [0001] The invention relates to a fee-controlling smart meter, in particular to a fee-controlling smart meter which is easy to assemble and disassemble. Background technique [0002] The smart meter is a new type of electric energy meter developed on the basis of the national grid smart meter series standards according to the overall requirements of the national grid construction. The smart electric meter has the functions of electric energy measurement, information storage, information processing, real-time monitoring, automatic control and information Interaction and other functions can effectively prevent arrears, and can effectively and timely manage users' electricity consumption scientifically. At present, smart energy meters are widely used in families, school student dormitories, collective dormitories of enterprises and institutions. [0003] However, there are many technical problems in existing smart watt-hour meters. For example, the current samp...

Problems solved by technology

In the current setting method of the current sampling shunt, the two sampling wires are on the same side of the current sampling shunt, so no matter how the two sampling wires are wound, it is difficult to reduce the area surrounded by the two wires. Therefore, The interference of the external magnetic field to the sampling signal is large, and the measurement accuracy of the electric energy meter cannot be guaranteed; at the same time, in the prior art, the position of the upper cover of the carrier corresponding to the button of the carrier is an opening suitable for the shape of the button. Once the shaft end of the carrier wave button is detached from the original fixing place, the carrier button as a whole is easy to fall out of the opening; in addition, in the prior art, commonly used lead seal structures include lead seal screws, lead seal wires and lead seals. The lead seal passes through the seal screw cap on the sealed object and connects with the sealed object. The two ends of the seal wire pass through the seal block and then tie a knot, and then press the seal block with lead seal pliers. flat

It is cumbersome, inconvenient to operate, and has relatively large restrictions on the structure of the shell. The use of traditional lead seals on the meter is cumbersome, unsightly, not smooth, and has poor sealing effect

[0004] At the same time, the auxiliary terminals in the smart meter in the prior art are all fixed on the housing of the meter by direct soldering, and the edge of the copper strip of the terminal exceeds the edge length of the auxiliary terminal, causing the copper strip of the terminal to be too long. Long, wasteful material and meter production costs
