A transformer bus protection device

Abstract

The invention discloses a transformer bus protection device. The transformer bus protection device comprises an upper shell, a lower shell and an outer shell, wherein a support plate is integratedly formed at a left side and a right side of the lower shell, the upper shell is inserted to an upper end of the lower shell, the outer shell sleeves outer walls of the lower shell and the upper shell, and a matching plate is integratedly formed on the outer shell and is matched with the support plate. The bus protection device designed by the invention has favorable sealing performance and favorablesupport performance; meanwhile, extra support performance also can be provided by a fixed rack and a support rack, and the risk that a bus is broken by an outer force is effectively reduced; and moreover, two stages of air cooling are employed in the device, the cooling demand of the bus is satisfied, an environment where the bus is arranged is completely isolated with the outside during the cooling process, so that the bus is prevented from being affected with damp and circuit-shorted, working safety and stability of a residential transformer are improved, and the transformer bus protection device has high practical value.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a transformer bus protection device. Background technique [0002] There are a large number of closed communities in my country. In order to facilitate power management, the same transformer is installed inside the community for power supply. However, due to the large scale of power consumption in my country's communities, it becomes more difficult to use traditional cables to transmit power to transformers. Instead, busbars are used for power transmission. has become mainstream. The bus bar is generally a metal strip with a rectangular or circular cross-section, which can be used for high-current power transmission due to its large cross-section, but there are many problems in bus power transmission.

The bus bar is generally a metal strip with a rectangular or circular cross-section. Because it has a large cross-section, it can be used for high-current power transmission, but there are many problems in bus power transmission.

[0003] First of all, the busbar is generally not equipped with a spare cable, so once it is broken by an external force, it will directly lead to the paralysis of the power system. Secondly, the busbar is generally a bare wire. If it is wet, it is very easy to cause a short circuit and cause a major accident, and because the current transmitted in the busbar is large, The heat dissipation section is small, so it is easy to heat up and fail, which will affect the stability of the circuit. Therefore, it is necessary to use appropriate auxiliary equipment to protect the busbar
