一种用于多台10kV柱上开关一次接线同时完成温升试验的方法
摘要：
本发明公开的一种用于多台10kV柱上开关一次接线同时完成温升试验的方法，包括如下步骤：步骤1：将一台大电流发生器的输出端通过测试线与一自动短接装置的输入端连接；步骤2：将自动短接装置的输入端与若干台10kV柱上开关的A、B、C端自动短接起来；步骤3：将每台10kV柱上开关的a、b、c端采用短接线短接起来，形成试验回路；步骤4：通过调节自动短接装置完成每台10kV柱上开关的每相电流的调节，达到每台柱上开关通过的电流为额定电流，满足试验要求后进行试验；步骤5：试验完成后，所述自动短接装置自动断开其输入端与若干台10kV柱上开关的A、B、C端短接。本发明可以大幅提高柱上开关的温升试验的效率。
摘要（英）：

The present invention discloses a method for completing temperature-rise tests of multiple 10kV pole-mounted switches simultaneously via one-time wiring, including the following steps: step 1: connecting an output terminal of a large current generator to an input terminal of an automatic short circuit apparatus by using a test wire; step 2: automatically short-circuiting the input terminal of theautomatic short circuit apparatus to terminals A, B and C of multiple 10kV pole-mounted switches; step 3: short-circuiting terminals a, b and c of each 10kV pole-mounted switch via short-circuiting wires to form a test loop; step 4: adjusting each phase current of each 10kV pole-mounted switch by adjusting the automatic short circuit apparatus, so as to enable a current passing through each pole-mounted switch to be a rated current, and conducting the test after a test requirement is met; and step 5: after the test is completed, automatically disconnecting the input terminal of the automatic short circuit apparatus and the terminals A, B and C of the multiple 10kV pole-mounted switches by the automatic short circuit apparatus. The method can greatly improve the efficiency of the temperature-rise test of the pole-mounted switches.
