户外预装式变电站（美式）概述 Overview

本智能型一体化变电站是推出的国产化美式箱变。该产品作为电缆化配电网中重要的供电单元，集高压控制、保护、变电、以及配电设备于一体的成套预装产品，广泛应用于城乡配电网之中。该产品将高压负荷开关、高压熔断器置于变压器油中，具有与变压器身共箱或分箱两种结构形式。油箱采用全密封结构，配有油温表、油位表、压力表、压力释放阀、放油阀等元件监测变压器运行状况。该产品分为环网型、终端型及电源型供电方式。为了使此种产品更适合于我国电网的实际要求，荣尔公司又推出了插拔型干式熔断器，熔丝的熔断不影响变压器油的性能。根据低压馈出要求的复杂程度，此产品分为标准型、加强型和综合型三种外壳形式，使用户和设计单位在选型时，做到更灵活、更经济。

This intelligent integrated transformer substation is a nationalized type American box substation developed by HONGTUO Company. As an important power supply unit in the cable distribution network, it is an in tegrated prefabricated product of high voltage control, protection, power transformation and power distribution, whichis

widely used in the urban and rural distribution network.The high voltage load switch and high voltage fuse are put into the transformer oil, so this product has two structure forms of one box and divided box with the transformer body. The oil box is of full-sealed structure with oil temperature indicator, oil level gauge, pressure gauge,

pressure relief valve and oil drain valve to monitor the operation condition of the transformer. This kind of products has three types of power supply modes ring network type, terminal type and power type. In order to make the product meet the actual demands of the power grid in China better, Ronger Company promotes plug-pull dry

type fuse and the fusing of the fuse wire has no effect to the performance of transformer oil. According to the complicated degree of low voltage outgoing demands, this product has three types of enclosure - standard type, reinforced type and integrated type, as a result, the clients and design agents have more choices.

户外预装式变电站（美式）结构特点 Structural features

箱壳骨架结构采用槽钢及角钢制造，有较高的机械强度，外壳采用铝合金板等材料制造，表面光滑平整，产品美观大方，且具有较好的防腐性能。箱体的基座高出地基300~600mm.

柜壳所有的门均向外开，开启角度大于90°，且设定位装置。并装有把手。暗门和能防雨、防堵、防锈的暗锁。箱体均为全密封防盗结构；为保证在一般周围空气温度下运行时，所有的电器设备的温度不超过其最大允许温度，箱体设有足够的自然通风口和隔热措施。预装式变电站的箱体设有专用接地导体，该接地导体上设有与接地网相连的固定连接端子，其数量为两个以上，有明显的接地标志。接地端子为直径不小于12mm 有铜质螺栓。接地导体采用铜带，其电流密度不大于200A/mm² 截面不小于30mm²，并保证流过最大短路电流时不发生过热和影响周围物体的安全。专用接地导体所承受的动、热稳定电流应与高压配电装置的接地方式相配合。

The framework structure of the box enclosure is made of channel steel and angle steel with higher mechanical strength. the enclosure is made of aluminum alloy plate with smooth surface, beautiful outline and better anticorrosion performance. the base of the box body is 300~600mm higher than the ground.All the doors of the

box enclosure are open to outside, and the opening angle is larger than 90° and is set with location device, handles, secret door, as well as built-in locks which have the functions of rain protection, anti-blockage and rust protection. the box bodies are of the full-sealed theft-proof structure. to assure the operation under the normal

ambient air temperature, the temperature of all the electrical equipment can’t exceed the maximum allowable temperature, and the box body has enough natural ventilation openings and heat insulation measures. the box body of the prefabricated substation is designed with special grounding conductor, on which there are more

than 2 fixed connecting terminals connected to the grounding network and on which there are obvious grounding marks. the grounding terminal is the copper bolt, the diameter of which is not less than 12mm. the grounding conductor is made from copper strip, the current density of which is not higher than 200A/mm2 and the cross

section of which is not less than 30mm2. and it is guaranteed that there is no overheat and there is no bad effect to the safety of the surrounding objects when the maximum short circuit current passes. the dynamic
