Description

Technical Field

[0001] This utility model relates to the field of busbar trunking technology, and in particular to a protective device. Background Technology

[0002] Busbar trunking is a highly efficient power distribution and transmission device, also known as a bus trunking system, used to transmit and distribute electrical energy in low-voltage power distribution systems. Compact busbar trunking is a prefabricated metal structure, typically made of aluminum or copper, with multiple conductors for transmitting and distributing electrical energy. It employs a modular design, consisting of multiple adjacent conductor units installed within a closed enclosure and isolated by insulating materials.

[0003] While high-density busbar trunking is mostly used indoors, some projects still require higher enclosure protection levels, such as IP65 or even IP66. Considering the impact of protection level on heat dissipation, higher protection levels lead to higher temperature rises. Therefore, most busbar trunking systems increase their protection level by applying sealant on-site, as their inherent structure cannot directly meet the requirements for high protection. This results in additional workload for on-site installation, and the varying skill levels of operators make it difficult to guarantee the effectiveness of the sealant application.
