[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0017] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0018] like Figures 1 to 5 The intelligent metering box device shown includes an intelligent metering box body 1 for providing space for the installation of internal components. The intelligent metering box body 1 is made of SMC material and has a structure design with protective features such as rainproof, dustproof and shockproof. Multiple protective covers 2 are installed inside the intelligent metering box body 1 for protection. The protective cover 2 has multiple plug-and-play electricity meter plug-ins 203 installed on its side. The bottom of each plug-in 203 is connected to multiple miniature circuit breakers 202 to ensure the safe and stable operation of the equipment via cables. The vertical inner wall of the smart metering box 1 is equipped with a smart door lock 201 to improve security and management convenience. The smart door lock 201 can be used to comprehensively analyze electricity theft models such as abnormal unlocking, abnormal opening of the meter cover, clock deviation, abnormal line loss value, and abnormal current to generate suspected electricity theft events and actively report them to the fusion terminal (ECU type or TTU type).

[0019] The vertical inner wall of the intelligent metering box 1 is equipped with an incoming main control switch 104 for controlling and protecting the entire circuit system. The handle of the incoming main control switch 104 is manually operated to close it. At this time, the circuit is connected, and the power supply can be supplied to the metering module and subsequent circuits through the incoming main control switch 104. When it is necessary to disconnect the circuit, or when there is an overload, short circuit or other abnormal situation in the circuit, the overload protection element (bimetallic strip) inside the incoming main control switch 104 bends and deforms under the heat generated by the overload current, pushing the tripping mechanism, or the strong magnetic field generated by the short circuit current drives the electromagnetic tripping device to act quickly, so that the switch automatically opens and disconnects the circuit. In addition, the incoming main control switch 104 can also be connected to the control module. The control module can perform the opening and closing operation of (104) through the control circuit according to the preset logic or the received remote command. The top of the incoming main control switch 104 is connected to the three-phase mutual inductor 105 for detection and protection system through the cable. The top of the three-phase mutual inductor 105 is connected to the terminal 107. By installing the incoming main control switch 104, the three-phase mutual inductor 105 and the miniature circuit breaker 202 module, the short circuit and grounding judgment of the meter box can be supported, the fault point can be accurately perceived, and the fault work order of short circuit and grounding in the meter box can be reported, supporting the precision of on-site fault repair. By collecting the status of the circuit breaker or reporting when there is an abnormality, the user's internal power outage perception can be realized, and the safety can be improved.

[0020] The interior of the smart meter box 1 is equipped with a displacement detection unit 106 for detecting the position of the smart meter box 1. The sides of the smart meter box 1 are equipped with two doors 101 that can be opened and closed for easy operation and maintenance.

[0021] Both doors 101 are equipped with multiple observation mirrors 102 for observing the internal tooling status. One door 101 has an electronic tag 103 for identifying the smart metering box 1 on its side. The smart metering box 1 has multiple heat dissipation vents 3 for exhausting hot air from inside the box. The heat dissipation vents 3 are equipped with dustproof nets for air circulation and heat dissipation inside the box, while preventing sand and dust from entering. The bottom of the smart metering box 1 has an inlet 301 for cable entry and exit.

[0022] Working principle When using this intelligent metering box device, first, the cable is threaded through the inlet 301 and connected to the various components inside the intelligent metering box 1. The three-phase transformer 105 can convert high voltage to low voltage and large current to small current, and detect and protect the system. When it is necessary to connect the circuit, the operator opens the box door 101 and manually operates the handle of the main control switch 104 to close it. At this time, the circuit is connected, and the power can supply power to the metering module and subsequent circuits through the main control switch 104.
