Abstract
The utility model relates to a rapid short-circuit device of a secondary side of a current transformer. The device is formed by fixed ends and a ground wire that is connected with the fixed ends; the fixed ends are connected in parallel to the ground wire by leads; and one end of the ground wire is grounded. Besides, the fixed ends can be conductive clamps, magnets, or short-circuit fixed devices. According to the utility model, due to implementation of the technical scheme, the provided device can be rapidly connected with a terminal strip for secondary connection; the time for the dielectric loss of the current transformer and the capacity measurement test can be shortened; the test quality can be ensued; and the regular checking efficiency can be improved.
Description
Technical field
The utility model relates to the quick short-circuit device of a kind of Current Transformer Secondary side.
Background technology
At present, when doing current transformer dielectric loss and capacity measurement test need short circuit secondary side, usually use fuse, and make shorting stub temporarily.A current transformer was made these needs of Dielectric Loss Test 2 ~ 5 minutes, just needed 10 ~ 20 minutes but make shorting stub and secondary side is carried out short circuit.This kind short circuit method has prolonged test period greatly.So need a kind of quick short-circuit device of development, shorten test period, improve and surely examine efficient.
Summary of the invention
The purpose of this utility model is to propose a kind of quick short-circuit device of Current Transformer Secondary side that is connected with secondary connection use terminal row fast.
The purpose of this utility model is achieved in that the quick short-circuit device of Current Transformer Secondary side, it is characterized in that: it is by stiff end, and the ground wire that links to each other with stiff end composition, and stiff end is connected in parallel on the ground wire by wire, ground wire one end ground connection.Described stiff end can be the clip of conduction, also can be magnet, can also be the short circuit stationary installation.
Owing to implementing technique scheme, this device can use terminal row to be connected with secondary connection fast, shortens current transformer dielectric loss and capacity measurement test period, and the warranty test quality improves and surely examines efficient.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the quick short-circuit device structural representation of magnet-type Current Transformer Secondary side;
Fig. 2 is the quick short-circuit device structural representation of wire-clamp-type Current Transformer Secondary side;
Fig. 3 is the quick short-circuit device structural representation of short connection type Current Transformer Secondary side.
Legend: 1, ground wire, 2, stylus, 3, leg, 4, fixed mount, 5, fixed block, 6, tension spring, 7, tension spring, 8, stiff end.
Embodiment: the utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, 2, 3, the quick short-circuit device of Current Transformer Secondary side is by stiff end 8, and ground wire 1 composition that links to each other with stiff end 8, and stiff end 8 links to each other with the current transformer with secondary connection use terminal row.Stiff end 8 is connected in parallel on the ground wire 1 by wire, ground wire 1 one end ground connection.Described stiff end 8 can be the clip of conduction, also can be magnet, can also be the short circuit stationary installation.
Described short circuit stationary installation is comprised of the stylus 2 and the leg 3 that are fixed on the fixed mount 4, and in 4 four jiaos of perforates of fixed mount, the hole lower port is provided with fixed block 5 outward, is inserted with leg 3 in the hole.Turning up in 5 times edges of fixed block, forms rib.Leg 3 bottoms are provided with the card rib, and cover has tension spring 6 between card rib and rib.Leg 3 lower end outsides offer back-shaped groove, and this groove and secondary connection use the terminal row outermost to buckle.Have groove in fixed mount 4 centers, fixed block 5 is laid at the outer interval of groove lower port, is inserted with stylus 2 in each fixed block 5, and stylus 2 lower ends are tip, and stylus 2 lower end upsides are provided with the card rib, are provided with tension spring 7 between card rib and rib.Stylus 2 upper ends are parallel on the ground wire 1, ground wire 1 one end ground connection.
When stiff end 8 was magnet, the secondary connection that magnet directly is adsorbed on current transformer used on the terminal row, and by the wire series connection, wire uses terminal row to be connected with secondary connection between each magnet.
When using the short circuit stationary installation to be connected with secondary connection use terminal row, leg 3 buckles with it, and stylus 2 lower ends contact with it.Be the fastness that guarantees to connect, the pulling force of tension spring 6 is greater than the tension force of tension spring 7.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
