Intelligent practical training device for electrified exchange of electric energy meter

Abstract

The invention belongs to the technical field of electrician practical training equipment, and particularly relates to an intelligent practical training device for electrified exchange of an electric energy meter. The device comprises an installation shell, a timer body, the three-phase intelligent electric energy meter, a concentrator, a combined junction box and a virtual load power amplifier arefixedly installed in the installation shell, filter screen plates are arranged at the two sides of the installation shell, installation blocks are fixedly connected to the two ends of each filter screen plate, placement grooves and strip-shaped grooves are formed in the two sides of the installation shell, fixing rods are fixedly connected to the interiors of the strip-shaped grooves, and the outer surfaces of the fixing rods are sleeved with springs. According to the invention, through the three-phase intelligent electric energy meter, the installation shell and a no-voltage and no-current timer, a practical trainee can operate better and is better improved in practical training, so that the problem that the workload of a trainer in practical training guidance and assessment is very large is avoided, and the phase of a fault can be judged timely and accurately.

Description

technical field [0001] The invention relates to the technical field of electrician training equipment, in particular to an intelligent training device for exchanging electric energy meters with electricity. Background technique [0002] In the management of power metering, when the electric energy meter enters the rotation cycle, the configuration does not meet the requirements, or the metering accuracy or functional failure occurs, the metering electric energy meter must be replaced. In order to minimize the impact on the user's electricity consumption, in addition In addition to the direct-connected watt-hour meter that must be replaced when the power is turned off, usually the high-voltage metering watt-hour meter and the low-voltage transformer-connected watt-hour meter adopt the method of live exchange for replacement operations. Higher risk. At the same time, there is also the problem of replenishing the electricity due to the transformer out of operation for a short t...
