Abstract

The invention provides a junction box with a load for replacing a metering device, and aims to solve the problem that power needs to be cut off when the metering device is replaced in the prior art. The junction box comprises a box body, a short-circuit plug, two live wire terminals and two null wire terminals; the live wire terminals are connected between a live wire and a corresponding live wire connector of the metering device, and the null wire terminals are connected between a null wire and a corresponding null wire connector of the metering device; the live wire terminals and the null wire terminals are arranged on the box body; and the box body is provided with a jack matched with the short-circuit plug, the two live wire terminals are turned on by the short-circuit plug, and the two null wire terminals are turned on by the short-circuit plug. The box body, the two live wire terminals and the two null wire terminals connect the live wire and the null wire with the metering device; when the short-circuit plug is plugged, the current of the live wire and the null wire passes through the short-circuit plug instead of the metering device, so when the metering device is replaced, a user does not need to cut off power; and more convenience is brought to power utilization of users.

Description

technical field [0001] The invention relates to a junction box for replacing a metering device with load. Background technique [0002] With the rapid development of social economy, the demand for continuity and stability of power quality is constantly increasing. At present, when the staff replaces the metering equipment, due to the basic structural design and technical reasons, the staff must first cut off the normal power consumption of the user before the replacement, and then restore it after the end. caused a power outage for the user. Although the time is not long, it will cause the user to call for inquiries if it is mild, and it will cause complaints from users if it is serious, and even damage the electrical appliances in the user's home. Contents of the invention [0003] The invention provides a junction box for replacing a metering device with load, aiming at solving the problem in the prior art that the metering device needs to be cut off when replacing the...
