The locking device is characterized in that the upper press plate is divided into a clamping end and a connecting end; the clamping end is fixed with the primary guide wire; the connecting end is perpendicular to the clamping end, and a pin hole is arranged in the connecting end; the axes of the pin hole is perpendicular to the primary guide wire; the device further comprises a connecting piece; the upper end of the connecting piece is provided with a groove matched with the connecting end of the upper press plate; the groove is connected with the connecting end of the upper press plate by a pin shaft; and the lower end of the connecting piece is connected with the upper end of the coupling capacitor. The clamping end of the upper press plate is provided with a groove; the device further comprises a lower press plate matched with the clamping end of the upper press plate; the lower press plate is further provided with a groove; and the primary guide wire is fixed between the groove of the clamping end of the upper press plate and the groove of the lower press plate. The locking device for the coupling capacitor with the structure is good in a locking effect, small in volume, compact and simple in structure, and easy to assemble and maintain since a bolt can not be influenced by the swinging of the primary guide wire,.
Description
Technical field
The utility model relates to a kind of locking device, relates in particular to a kind of be used to prevent lead and the loosening locking device of coupling capacitor.
Background technology
In electric power system, coupling capacitor is one of electric equipment important in the electric power system.Coupling capacitor is mainly used in hf channel, makes two systems of forceful electric power and light current through capacitor-coupled and isolation, and the high-frequency signal path is provided, and stops power current to get into weak electricity system, guarantees personal safety.The coupling capacitor that has capacitor-voltage detecting device also can extract power-frequency voltage and supply protection and reclosing to use except that above effect, plays the effect of voltage transformer.
In the running, coupling capacitor leans on single bolt to be connected with a lead mostly at the scene.So occur causing the swing of a lead often, thereby cause bolt looseness because of extraneous wind-force.Because the loose contact that bolt looseness causes discharges and recharges faults such as instability in the time of can causing two systems of forceful electric power and light current through capacitor-coupled, bring very big hidden danger for the safety in production of electric energy.
The utility model content
To the technical problem of above-mentioned existence, the utility model provides a kind of coupling circuit check device, can prevent because becoming flexible between the coupling circuit that the swing of lead causes and the lead.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of coupling capacitor locking device comprises a top board that is used to connect lead and coupling capacitor, and it is characterized in that: described top board is divided into bare terminal end and link; Said bare terminal end and a lead fixed; Said link is vertical with bare terminal end, and link is provided with pin-and-hole; The axis of said pin-and-hole is vertical with a lead; Also comprise a connector; The upper end of said connector is provided with the groove that cooperates with the link of top board; Said groove relies on bearing pin to be connected with the link of top board; The lower end of said connector is connected with the coupling capacitor upper end.The bare terminal end of top board is provided with groove; Also comprise a lower platen that cooperates with the top board bare terminal end; Said lower platen also is provided with groove; Lead fixed is between the groove of the groove of top board bare terminal end and lower platen.
As a kind of improvement, the bare terminal end of said top board is provided with groove; Also comprise a lower platen that cooperates with the top board bare terminal end; Said lower platen also is provided with groove; Lead fixed is between the groove of the groove of top board bare terminal end and lower platen.
As a kind of improvement, be provided with insulating part between said connector and the coupling capacitor.
The usefulness of the utility model is:
Coupling capacitor locking device with said structure, because the swing of a lead can not impact bolt, anti-loosing effect is good, and volume is little, compact conformation, simple is easy to assembling and safeguards.Utilize upper and lower pressing plate to fix a lead, be convenient to loading and unloading.Be provided with insulating part between connector and the coupling capacitor other electric equipments are played the better protection effect.
Description of drawings
Fig. 1 is this use new structure sketch map.
Mark among the figure: 1 lower platen, 2 top boards, 2a bare terminal end, 2b link, 3 connectors, 4 insulating parts, 5 coupling capacitors, 6 leads, 7 fixed heads.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1:
The utility model comprises a top board 2 that is used to connect lead 6 and coupling capacitor 5, and it is characterized in that: described top board 2 is divided into bare terminal end 2a and link 2b; Said bare terminal end 2a and a lead 6 are fixing; Said link 2b is vertical with bare terminal end 2a, and link 2b is provided with pin-and-hole; The axis of said pin-and-hole is vertical with a lead 6; Also comprise a connector 3; The upper end of said connector 3 is provided with the groove that cooperates with the link 2b of top board 2; Said groove relies on bearing pin to be connected with the link 2b of top board 2; The lower end of said connector 3 is connected with coupling capacitor 5 upper ends.Be provided with insulating part 4 between connector 3 and the coupling capacitor 5.In addition, coupling capacitor 5 lower ends can also fixedly mount fixed head 7.Fixed head 7 relies on bolt and coupling capacitor 5 to fix.Fixed head 7 is used for fixing coupling capacitor 5.
When using, one time lead 6 swings with the wind, also drives top board 2.Because the motion of the link 2b of top board 2 receives the restriction of groove two walls of connector 3, can not impact bolt.Therefore effectively solved the loosening problem between lead 6 and the coupling capacitor 5.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
