Abstract

The invention provides a power-off-free meter changing device. The device comprises a wiring terminal box, and a wire incoming terminal, a first wire outgoing terminal, a second wire outgoing terminal and a switching copper sheet are arranged in the wiring terminal box; the wire incoming terminal is connected with a live wire inlet, the first wire outgoing terminal is connected with the wire inlet end of an electricity meter, the wire outlet end of the electricity meter is connected with the second wire outgoing terminal, and the second wire outgoing terminal is connected with a user side air switch; and one end of the switching copper sheet is fixedly connected with the wire incoming terminal, and the other end of the switching copper sheet switches the connection position between the first wire outgoing terminal and the second wire outgoing terminal. When the electricity meter needs to be replaced, the other end of the switching copper sheet is rotated from the first wire outgoing terminal to the second wire outgoing terminal, so that no current is input at the wire incoming terminal of the electricity meter when the electricity meter is replaced, and continuous power supply on a user side is realized without being influenced. The device is simple in structure, convenient to use and safe to operate.

Description

technical field [0001] The present invention relates to the technical field of electric equipment, and more specifically, to a meter changing device without power failure. Background technique [0002] At present, most Xintou residential quarters use the form of containerized meters for meter reading to households. The currently used method of loading meters in containers and wiring can only be replaced after a power outage, which has the following disadvantages: 1. The customer cannot be contacted and notified in time: the customer has changed the contact information but has not informed the power supply company, and the staff cannot Contact and inform the customer of the power outage and replacement of the electric meter in time; 2. The customer's electrical equipment is damaged due to the power outage: once there is a power consumption customer's home, there is a 24-hour uninterrupted electrical equipment, such as continuous oxygen supply tropical fish equipment, medical ...
