Description

Technical Field

[0001] This utility model relates to the technical field of outdoor pressure-resistant high-voltage ring network boxes, specifically an outdoor pressure-resistant high-voltage ring network box. Background Technology

[0002] The outdoor ring main unit microcomputer integrated protection device is an economical protection system integrating measurement, control, protection, and communication. Custom-designed for high-voltage distribution cabinets in distribution networks, it features three-stage omnidirectional current protection as its core and is equipped with power grid parameter monitoring and acquisition functions. It eliminates the need for traditional ammeters, voltmeters, wattmeters, frequency meters, and electricity meters. Measurement data and protection information can be remotely transmitted to a host computer via a communication port, facilitating distribution network automation. Based on the characteristics of distribution network power supply, the device integrates a backup power automatic transfer function, flexibly enabling incoming line backup transfer and busbar backup transfer functions. The integrated protection device adopts internationally advanced DSP and surface mount technology, as well as flexible fieldbus technology, to meet the requirements of different voltage levels in substations. It realizes the coordination, digitalization, and intelligence of substations. This series of products can complete the functions of protection, measurement, control, regulation, signaling, fault recording, electricity acquisition, low current grounding line selection, and underfrequency load shedding in substations. This makes the technical requirements, functions, and internal wiring of the products more standardized. The products adopt distributed protection and control devices, which can be centrally assembled or installed in a decentralized manner. The configuration can also be changed arbitrarily according to user needs to meet different scheme requirements.

[0003] However, it still has some drawbacks. For example, most of the vents only have movable vanes, which provide ventilation, but also allow dust to enter the equipment. Furthermore, the fixing devices used when moving the high-voltage electrical box are prone to damage. For instance, existing fixing devices are mostly simple single-ring or single-bolt structures, which cause stress concentration when hoisting heavy boxes, making them prone to plastic deformation or breakage, resulting in poor stability and safety hazards.

[0004] To address the aforementioned issues, this application proposes an outdoor pressure-resistant high-voltage ring network box. Summary of the Invention
