Description
Technical Field
The invention relates to the technical field of high-voltage switch detection equipment, in particular to a medium-high voltage ultra-fast switch and detection equipment thereof.
Background
The high voltage is an electric service wire of which the alternating voltage of a distribution line is more than 1000V or the direct voltage is more than 1500V. The low voltage is low voltage when the alternating current low voltage is below 1000V or the direct current voltage is below 1500V.
The safe voltage does not exceed 36V of alternating current and 50V of direct current. The 1000KV and above ac voltage class in the power system supplies extra-high voltage power, and is generally used only as large power long-distance transmission line because the energy loss during transmission can be reduced. The voltage used in different fields is different because according to the formula P ═ IU, in order to reduce the loss of electric energy in the transmission process, the current must be reduced, and to ensure the total power is not changed, the voltage must be properly increased, and the electric energy passes through a voltage reduction substation and finally reaches the home of a user.
The high-voltage switch is important control and protection equipment in electrical equipment of a power plant and a transformer substation, can be used for opening and closing a circuit to realize control on the high-voltage circuit, and can be used for automatically opening the circuit when the circuit is overloaded or short-circuited, so that the circuit and the electrical equipment are protected. The high-voltage switch needs to be subjected to final inspection before being produced, packaged and delivered from a factory, and the final inspection comprises electrical test links such as loop withstand voltage test and loop resistance test and appearance inspection; when a loop voltage withstand test or a loop resistance test is carried out, the tulip contact of the high-voltage switch needs to be connected with a final inspection system through a test contact on test equipment to form a test loop; because the inner diameters of the tulip contacts of the high-voltage switches of different models are different, in order to ensure that the tulip contacts can be tightly connected with the test contacts, when the high-voltage switches of different models are tested, the test contacts matched with the sizes of the tulip contacts are required to be used, the test contacts used by the existing high-voltage switch final inspection equipment are fixed in size, when the high-voltage switches of different models are tested, the test contacts need to be manually replaced, and when the high-voltage switches are replaced, the whole test contacts need to be detached and replaced by new test contacts, so that the operation is complicated and the efficiency is low.
