    • The present invention relates to a Compact Secondary Substation comprising a fault protection system and a method for fault protection in Compact Secondary Substations (CSS). The CSS comprises a Ring Main Unit (RMU), a transformer and a Low Voltage (LV) switchgear.The object of the invention is to fault protect a secondary switchgear, a further object of the invention is in fault situations to bring the secondary switchgear back in operation as soon as possible. The objects can be fulfilled by a system where the CSS comprises a number of detectors (114, 116, 118, 126, 128, 134), which detectors can be placed at least in one of the RMU, the transformer or in the LV switchgear, which detectors can be connected to a control unit (106), which control unit by fault detection by the detectors can activate a fast operating switch (112) for grounding. By using the fast operating grounding switch (112) and controlling this on the basis of the detectors placed inside the CSS, an active arc fault protection is achieved. The control unit (106) also controls the fast operating grounding switch (112) so that it works as a working grounding switch.
    • 本发明涉及一种紧凑型二次变电站,其包括故障保护系统和紧凑型二次变电站(CSS)中的故障保护方法。 CSS包括环形主单元(RMU),变压器和低压(LV)开关设备。本发明的目的是对二次开关设备进行故障保护,本发明的另一个目的是在故障情况下使二次开关柜 尽快恢复运作。 这些物体可以通过系统来实现,其中CSS包括多个检测器(114,116,118,126,128,134),该检测器可以至少放置在RMU,变压器或LV开关柜中的一个中 ,哪些检测器可以连接到控制单元(106),通过检测器的故障检测,该控制单元可以激活用于接地的快速操作开关(112)。 通过使用快速操作的接地开关(112)并根据放置在CSS内部的检测器进行控制,可实现有源电弧故障保护。 控制单元(106)还控制快速操作的接地开关(112),使其作为工作接地开关。

    • The present invention relates to a Compact Secondary Substation (CSS) containing at least one transformer (6, 108, 208) which is connected to a high voltage input (110, 210) and through a low voltage switch board (112, 212) to consumers. The object of the invention is to perform cooling of a CSS in a way that mostly isolates the inner volume of the CSS from atmospheric air. This object can be fulfilled if the transformer is cooled by a cooling system comprising a heat exchanger (8, 104, 214) in which a first medium and a secondary medium are circulated, where the first medium contains heat generated by the transformer and the secondary medium is circulated through pipes or tubes arranged in the soil around the CSS and is thus cooled by heat transmission towards the soil. Such a CSS can also have a much smaller volume than a typical air-cooled CSS.
    • 本发明涉及包含至少一个变压器(6,108,208)的小型次级变电站(CSS),其连接到高电压输入端口(110,210),并通过低压开关板(112,212)连接到 消费者。 本发明的目的是以大部分将CSS的内部容积与大气隔离的方式进行CSS的冷却。 如果变压器由包括第一介质和第二介质循环的热交换器(8,104,214)的冷却系统来冷却,则第一介质包含由变压器产生的热量和次级 介质通过布置在CSS周围的土壤中的管道或管道循环,并因此通过向土壤的热传递而被冷却。 这样的CSS也可以比典型的空气冷却CSS小得多的体积。

    • There is disclosed an adapter in combination with an MCCB having terminals for incoming and outgoing terminals and to be placed on a low voltage switchboard. The switchboard comprises a set of busbars and is used in distributing electrical energy to consumers. The adapter comprises an adapter base to which connectors are mounted. The connectors are connected to the busbars and to said incoming or outgoing terminals of the MCCB. The product improves the installation phase of the MCCB and also allows easing of the production of the mechanical fastening device. The adapter base has an opening, and aligned first ends of said connectors extend through said opening and are arranged at a front side of the adapter base in order to form the incoming or outgoing terminals to be placed in the terminals of the MCCB. Moreover the second end of said connectors are provided with a clamp being arranged in predefined different positions at the rear side of the adapter base corresponding to the positions of the busbars and having a clamping part for gripping over a busbar to establish electrical connection and mechanical stability. Each clamp has a tightening means aligned with a hole in said adapter base to be operated from the front side of the adapter base through said hole.
