A compact alternative low-voltage switchgear includes a front enclosure and a rear enclosure connected to the rear of the front enclosure. The front enclosure contains an incoming line compartment, a metering compartment, a secondary wiring compartment, and a circuit breaker mounting compartment. The incoming line compartment and the metering compartment are vertically aligned and interconnected. The secondary wiring compartment is located beside the incoming line compartment and the metering compartment, and a first partition is provided between the secondary wiring compartment and the incoming line compartment and the metering compartment. The circuit breaker mounting compartment is located below the metering compartment and the secondary wiring compartment, and a second partition is provided between the circuit breaker mounting compartment and the metering compartment and the secondary wiring compartment. Ventilation holes are provided on both the second partition and the first partition. The rear enclosure contains a capacitor bank switch compartment and a capacitor mounting compartment, located vertically and vertically respectively. This invention provides a compact alternative low-voltage switchgear with high space utilization, a reasonable layout, and good heat dissipation and maintenance convenience.

This invention relates to the field of building engineering technology, specifically to a non-vibration pressure grouting construction method for tall steel-concrete composite columns. S1: Grouting holes are opened at the bottom of the steel-concrete column, and vent holes are opened at the top. S2: A grouting connection structure is installed, and a grouting connection pipe is welded at an acute angle to the column axis and extends into the column. A check valve is installed on the pipe, and reinforcing ribs are welded between the pipe and the column. S3: Pressure grouting is performed from the compacted concrete until it overflows from the vent holes. S4: After the concrete has settled naturally, secondary grouting is performed until it overflows from the vent holes again. S5: The check valve is closed to prevent backflow. S6: The grouting holes are sealed after the concrete reaches 70% of its design strength. This invention, through a grouting connection structure with a check valve and reinforcing ribs, combined with a secondary grouting process, systematically solves the problems of concrete backflow, insufficient compaction at the top of the column, and easy damage to the connection structure during the initial jacking process of ultra-high-rise buildings. It significantly improves construction quality, safety, and efficiency, and is applicable to the construction of tall steel-concrete composite columns in industrial and civil buildings.

The application discloses an encoder training method based on decoder side assistance, a feedback method, a terminal device, a network device and a system. The method comprises the following steps: a terminal device acquires decoder side assistance training data; the terminal device encodes target channel state information in a local training data set to obtain feedback load, and reconstructs the feedback load by using the decoder side assistance training data to obtain reconstructed channel state information; finally, a loss function constructed by using the target channel state information and the reconstructed channel state information is used to train an encoder to obtain a trained encoder. The application can make the encoder more adaptive to the channel characteristics of the terminal device, better exert the active adaptation capability of the terminal device, and improve the reconstruction quality of the channel state information while ensuring the intercommunication of the encoder and the decoder, thereby improving the transmission performance of the whole communication system.
