Description

But quick assembly disassembly's direct current fills stake power module soon Technical Field The utility model belongs to the technical field of charging piles, and particularly relates to a direct-current quick-charging pile power module capable of being quickly disassembled and assembled. Background Along with the rapid popularization of new energy automobiles, the direct current rapid charging pile is used as core energy supplementing equipment, and higher requirements are put on the power density, the heat dissipation performance and the operation and maintenance efficiency of a power module of the direct current rapid charging pile. The traditional direct current fast filling pile power module adopts a bolt fixing or welding integration mode, and although the basic functions can be met, the following obvious defects are exposed in practical application: The installation and maintenance efficiency is low, the existing module depends on a plurality of groups of bolts to fasten (usually 8-12M 6 bolts are needed), holes are positioned one by one during installation, and special tools are used for tightening, so that the time for single disassembly and assembly is as long as 30-45 minutes. Frequent mechanical operations during peak operation and maintenance periods tend to lead to thread slippage (incidence > 18%), further increasing maintenance costs. In addition, although the stability of the welded structure is improved, the module needs to be cut and disassembled when damaged, the maintenance period is prolonged to 2-3 days, and the availability of the charging pile is severely restricted. The anti-vibration and anti-loose capability is insufficient, the traditional bolt fixation depends on static pretightening force, and under the action of long-term running vibration (typical frequency is 5-200 Hz) of the charging pile, the bolt is easy to be subjected to stress relaxation, so that the contact resistance is increased (the degradation rate is about 0.5 mu omega/month), and local overheating and even ablation are caused. Experimental data show that after the conventional structure continuously vibrates for 48 hours, the locking force is attenuated by 35%, and serious potential safety hazards exist.
