Embodiment 1

[0054] This embodiment provides an emergency power supply method for a metering turnover cabinet, which can provide emergency power supply for a metering turnover cabinet with a power of 150W (watts), see figure 1 , the method flow provided by this embodiment is specifically as follows:

[0055] 101. The dual power supply switch monitors the power supply of the external power supply to the metering turnover cabinet in real time;

[0056] 102. When the dual power supply switch detects that the external power supply stops supplying power to the metering turnover cabinet, the dual power supply switch switches the connection between the external power supply and the metering turnover cabinet to the connection between the metering turnover cabinet's own emergency power supply and the metering turnover cabinet connect;

[0057] Among them, there are many reasons for the external power supply to stop supplying power to the metering turnover cabinet, for example: the external power s...

Embodiment 2

[0079] This embodiment provides an emergency power supply system for metering turnover cabinets, see figure 2 , because the problem-solving principle of the metering turnover cabinet emergency power supply system is the same as figure 1 The emergency power supply method of the metering turnover cabinet shown is similar, so the implementation of this system can be found in figure 1 The embodiment of the method shown is not repeated here.

[0080] The emergency power supply system for the metering turnover cabinet provided in this embodiment includes: an external power supply 201, a metering turnover cabinet 202, a dual power supply switch 203, a self-contained emergency power supply 204 for the metering turnover cabinet, and an inverter 205;

[0081] Wherein, the power of the metering turnover cabinet 202 is 150W;

[0082] One end of the dual power switch 203 is connected to the external power supply 201, and at the same time this end is connected to the inverter 205, and th...

Abstract

The invention relates to an emergency power supplying method, owned emergency power source and emergency power supplying system of a measurement transferring cabinet, and belongs to the technical field of electric power systems. The method includes the steps that when a dual-power selector switch monitors that an external power source stops supplying power to the measurement transferring cabinet, the dual-power selector switch changes the connection between the external power source and the measurement transferring cabinet into the connection between the owned emergency power source of the measurement transferring cabinet and the measurement transferring cabinet; the owned emergency power source of the measurement transferring cabinet supplies power to the measurement transferring cabinet. According to the method, when the external power source stops supplying power to the measurement transferring cabinet, the dual-power selector switch changes the connection between the external power source and the measurement transferring cabinet into the connection between the owned emergency power source of the measurement transferring cabinet and the measurement transferring cabinet, and the owned emergency power source of the measurement transferring cabinet supplies power to the measurement transferring cabinet, so that normal power supplying of the measurement transferring cabinet is guaranteed under the condition that the external power source stops supplying power to the measurement transferring cabinet, and the utilization requirements of measurement-instrument out-in-warehouse handling and meter-installation power supplying of normal measurement persons are met.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an emergency power supply method for a metering turnover cabinet, a self-contained emergency power supply, and an emergency power supply system. Background technique [0002] At present, the third-level warehouses of power supply enterprises are used to store the metering turnover cabinets for electric energy meters. The efficiency of asset entry and exit, and at the same time prevent the occurrence of asset outflow. [0003] Through the use of turnover cabinets for a period of time, it is found that in the case of power outages and power failures in the office, the turnover cabinets cannot be used normally, which brings inconvenience to the management of the metering assets in and out of the power supply station and the asset collection of meter installation and connection personnel, directly affecting The time limit for meter installation and power connection is added. ...
