Description
Technical field
The utility model relates to electric power system test grounding technology field, relates in particular to a kind of contact electric equipment secondary terminals short circuit jockey.
Background technology
Electric equipment is in operation, and it is deteriorated that electric insulation can be occurred by the effect of electric field, temperature and mechanical oscillation for a long time gradually, deteriorated deteriorated with part comprising entirety, forms defect.AC voltage withstand test is to identify insulation of electrical installation intensity the most effectively and the most direct method, is an important content of preventive trial.In addition, because AC voltage withstand test voltage is generally high than working voltage, after test, equipment has larger margin of safety, and therefore AC voltage withstand test is a kind of important means that guarantees electric equipment safe operation.But, when the electric equipments such as current transformer, voltage transformer, arc suppression coil, GIS/HGIS are carried out to AC voltage withstand test, its secondary circuit etc. must be carried out to short circuit grounding.Traditional short circuit mode is: wire is crimped on below electric equipment secondary terminals screw, reaches the object of ground connection after the wiring of short circuit secondary terminals.But because the terminal on electric equipment is more, secondary terminals present position is often narrower and small, secondary terminals being carried out to when short circuit connects needing the connection of a terminal of a terminal, so be difficult to fast by all smooth short circuit groundings of secondary terminals.In addition, when the short circuit connecting line adopting at present carries out short circuit and connects many electric equipments, need frequently dismounting screw etc., very loaded down with trivial details time-consuming, reduces operating efficiency greatly.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, convenient and swift, and short circuit electric equipment secondary terminals fast and accurately completes the contact electric equipment secondary terminals short circuit jockey of AC voltage withstand test work.
For realizing the technical scheme that the purpose of this utility model adopts, be: a kind of contact electric equipment secondary terminals short circuit jockey, comprise earth clamp, wire and terminal short-circuit device, one end of described wire is connected with earth clamp, and the other end is connected with terminal short-circuit device.
Described terminal short-circuit device comprises software magnetic stripe and be arranged on the helical metal wire on described software magnetic stripe, and described wire is connected with described wire.
Described terminal short-circuit device comprises software magnetic stripe and be arranged on the wavy flexible sheet metal piece on described software magnetic stripe, and described sheet metal is connected with described wire.
Described software magnetic stripe arranges insulating barrier.
Described terminal short-circuit device comprises flexible rubber bar and is arranged on the some U-shaped folder on described rubber strip, is mutually electrically connected and is electrically connected with wire between described some U-shaped folders.
The utility model terminal short-circuit device connects, effectively realized the short circuit of electric equipment secondary terminals has been connected, and connect earth clamp by wire, effectively realized the short circuit grounding to electric equipment secondary terminals, terminal short-circuit device adopts software magnetic stripe and helical metal wire, the two all has good pliability, can the terminal of the multiple different azimuth on electric equipment be all shorted together by repeatedly bending fast, easy, quick; In addition, because software magnetic stripe self has certain magnetic, ferrous metal silk is had to certain suction-operated, therefore can effectively avoid the wire chip in use rupturing to drop to inside electric appliance, ensure the safe and stable operation of electric equipment.Further, by adopting, wavy flexible sheet metal piece is set on software magnetic stripe, can easily electric equipment secondary terminals be connected in to wavy flexible sheet metal piece, realize the short circuit grounding of secondary terminals; Further, by adopting, some U-shaped folders that are interconnected are set on flexible rubber bar, can, when carrying out short circuit connection, fast U-shaped folder be clamped to each secondary terminals, guaranteed the reliable short circuit of each terminal.The utility model is easy, practical, cost is low, is conducive to increase work efficiency, and thoroughly eliminates current unfavorable factor, reaches the effect of putting things right once and for all, and is convenient to promote the use of.
