山东电气成套设备中变压器的安装位置科普：与适配的双重考量

　　Popular science on the installation location of transformers in Shandong Electric's complete equipment: dual considerations of safety and adaptability

　　在电气成套设备系统中，变压器的安装位置直接关系到设备运行、维护便捷性与整体性能发挥。不少行业同仁在安装布局时容易忽视环境适配与规范要求，埋下隐患。作为电气成套生产厂家，今天就为大家详细拆解变压器在电气成套设备中的常见安装位置，结合适配场景与规范要求，助力科学布局。

　　In electrical equipment systems, the installation position of transformers directly affects the safe operation, maintenance convenience, and overall performance of the equipment. Many industry colleagues tend to overlook environmental adaptation and regulatory requirements when installing layouts, which can lead to safety hazards. As a manufacturer of electrical complete sets, today we will provide a detailed breakdown of the common installation positions of transformers in electrical complete sets of equipment, combined with adaptation scenarios and regulatory requirements, to assist in scientific layout.

　　独立变配电所：油浸式变压器的“专属区”

　　Independent Substation: Exclusive Safety Zone for Oil Immersed Transformers

　　独立变配电所是油浸式变压器的核心安装场景，其设计初衷围绕油浸式变压器的特性展开。

　　The independent substation is the core installation scenario of oil immersed transformers, and its design intention revolves around the safety characteristics of oil immersed transformers.

　　油浸式变压器依靠绝缘油散热，若发生泄漏可能引发火灾风险，因此需安装在独立的变配电所内，通过物理隔离避免对其他电气设备和操作人员造成影响。

　　Oil immersed transformers rely on insulating oil for heat dissipation, and leakage may pose a fire risk. Therefore, they need to be installed in independent substations to avoid affecting other electrical equipment and operators through physical isolation.

　　这类安装位置通常具备专门的防火、防爆与通风设施，能有效应对油浸式变压器运行时的散热需求与风险，是保障电力系统稳定的重要布局方式，常见于变电站、大型工业厂区的配电。

　　This type of installation location usually has specialized fire, explosion, and ventilation facilities, which can effectively meet the heat dissipation requirements and safety risks during the operation of oil immersed transformers. It is an important layout method to ensure the stability of the power system and is commonly used in substations and distribution centers in large industrial plants.

　　室内变压器室：干式变压器的“防护主场”

　　Indoor transformer room: the "protective main field" of dry-type transformers

　　室内变压器室专为干式变压器设计，根据设备防护等级分为两种安装形式。

　　The indoor transformer room is designed specifically for dry-type transformers and is divided into two installation forms based on the equipment protection level.

　　无防护外罩的干式变压器必须安装在单独的变压器室内，通过封闭空间提供必要的防尘、防触碰防护，避免外界环境对设备的侵蚀与人员误触风险。

　　Dry type transformers without protective covers must be installed in separate transformer rooms, providing necessary dust and touch protection through enclosed spaces to avoid external environmental erosion of equipment and the risk of accidental contact by personnel.

　　带有防护外罩（防护能力不低于IP2X）的干式变压器，虽可安装在普通室内环境，但需与其他电气设备保持适当距离，确保散热通畅且不影响周边设备运行，适用于高层建筑、医院、商业综合体等室内配电场景。

　　Dry type transformers with protective covers (with a protection capacity not lower than IP2X) can be installed in ordinary indoor environments, but they need to maintain an appropriate safe distance from other electrical equipment to ensure smooth heat dissipation and not affect the operation of surrounding equipment. They are suitable for indoor power distribution scenarios such as high-rise buildings, hospitals, and commercial complexes.

　　与低压柜组合安装：空间优化的“集成方案”

　　Combined installation with low-voltage cabinet: an integrated solution for space optimization

　　在空间有限的配电场景中，干式变压器可与低压柜组合安装，但需严格遵循防护等级对应的间距要求。

　　In limited space distribution scenarios, dry-type transformers can be installed in combination with low-voltage cabinets, but the spacing requirements corresponding to the protection level must be strictly followed.

　　若干式变压器防护外罩达到IP3X，具备较强的防尘与防触碰能力，可与低压开关柜贴邻安装，实现空间利用，适配小型配电室、车间配电房等紧凑布局场景。

　　Several types of transformer protective covers reach IP3X, with strong dust and touch resistance, and can be installed adjacent to low-voltage switchgear to achieve efficient space utilization, suitable for compact layout scenarios such as small distribution rooms and workshop distribution rooms.

　　若防护外罩为IP2X，防护等级相对较低，其与低压柜的小净距不宜小于0.8m，通过预留足够空间保障散热效果与检修通道，避免因距离过近导致热量积聚或维护不便。

　　If the protective cover is IP2X and the protection level is relatively low, the minimum clear distance between it and the low-voltage cabinet should not be less than 0.8m. Adequate space should be reserved to ensure heat dissipation and maintenance channels, avoiding heat accumulation or inconvenient maintenance due to close proximity.

　　户外箱式变电所：户外场景的“一体化布局”

　　Outdoor Box type Substation: Integrated Layout for Outdoor Scenarios

　　户外箱式变电所是针对户外安装需求设计的一体化解决方案，内部集成了变压器、配电柜等核心设备，适用于户外配电场景。

　　Outdoor box type substation is an integrated solution designed for outdoor installation needs, which integrates core equipment such as transformers and distribution cabinets, and is suitable for outdoor power distribution scenarios.

　　安装时需关注基础验收，变电所基础必须高于室外地坪，防止雨水倒灌；同时确保周围排水通畅，避免积水侵蚀设备底部。

　　During installation, special attention should be paid to foundation acceptance. The foundation of the substation must be higher than the outdoor floor to prevent rainwater from flowing back; At the same time, ensure smooth drainage around and avoid water accumulation from eroding the bottom of the equipment.

　　这类安装位置无需单独建设厂房，布局灵活且施工便捷，广泛应用于城市郊区、住宅小区、户外充电桩集群等户外配电需求场景，能有效适应户外复杂的气候环境。

　　This type of installation location does not require a separate factory building, with flexible layout and convenient construction. It is widely used in outdoor power distribution demand scenarios such as suburban areas, residential communities, and outdoor charging pile clusters, and can effectively adapt to complex outdoor climate environments.

　　厂家安装建议

　　Professional installation suggestions from manufacturers

　　作为电气成套生产厂家，提醒大家：选择变压器安装位置时，需先明确变压器类型（油浸式/干式）、防护等级，结合安装环境（室内/户外）与空间条件综合判断；严格遵循电气安装相关标准，关注防火间距、散热空间、防护隔离等核心要求。安装前务必核对设备参数与安装环境的适配性，建议由技术人员现场勘查规划，避免因布局不当导致设备故障或事故。

　　As an electrical complete set manufacturer, we remind everyone that when choosing the installation location of transformers, it is necessary to first clarify the transformer type (oil immersed/dry-type), protection level, and make a comprehensive judgment based on the installation environment (indoor/outdoor) and spatial conditions; Strictly follow the relevant standards for electrical installation, with a focus on core requirements such as fire separation distance, heat dissipation space, and protective isolation. Before installation, it is necessary to check the compatibility between the equipment parameters and the installation environment. It is recommended that professional technicians conduct on-site investigation and planning to avoid equipment failure or safety accidents caused by improper layout.

　　结语
