Abstract
The utility model discloses an impact interlocking device of a high-voltage fuse, comprising an impact plate (1), an insulated revolving rod (2), a connecting rod (3) and a microswitch (4), wherein the impact plate (1) is connected with one end of the insulated revolving rod (2) and fixed on a fixed support (5), and the other end of the insulated revolving rod (2) is connected with the connecting rod (3); the microswitch (4) is arranged on a microswitch frame (6), the microswitch frame (6) is also provided with a slideway (7); the other end of the connecting rod (3) is also connected and provided with a screw shaft (10) which can slide in the slideway (7); and beside the slideway (7), a top plate (8) which can force the connecting rod to rotate around the shaft, change angle and impact the microswitch (4) to move when the connecting rod (3) drives the screw shaft (8) to slide in a linear way is arranged. The impact interlocking device can be flexibly used in various occasions where high-voltage fuses are used for protecting circuits; the parts are convenient for assembly; and the impact interlocking device has good universality and can be installed randomly along with the high-voltage fuse.
Description
Technical field
The utility model relates to a kind of fuse interlock of switchgear assembly, particularly a kind of high-tension fuse bump interlock.
Background technology
The ac high-voltage switchgear assembly mainly comprises control loop and three-phase major loop.When the major loop of three-phase alternating current when wherein certain short trouble occurs mutually, by this phase fuse fusible core that is contained in the loop its short circuit current is disconnected, the striker of top opening can produce the bump action to high-tension fuse bump interlock rapidly on this phase fuse simultaneously.The instruction that all the other two-phase currents rely on the striker bump high-tension fuse bump interlock on the short circuit phase fuse to provide is moved the electric mechanical switch of control major loop operating current rapidly, cut off the electric current of all the other two-phases, thereby the situation that prevents phase-deficient operation occurs.
Existing high-tension fuse bump interlock all is a specialized designs, is attached on the special switch, and versatility is poor, and when high pressure switchgear assembly electric appliance component changed, original interlock just can not use.
The utility model content
The purpose of this utility model provides a kind of high-tension fuse bump interlock that can be used in the use occasion of various high-tension fuse protective circuits neatly.
For achieving the above object, the technical solution of the utility model is: a kind of high-tension fuse bump interlock, comprise crash panel, insulation bull stick, connecting rod and sensitive switch, crash panel is connected with the insulation bull stick and is fixed on the fixed support, and an end of insulation bull stick is connected with connecting rod; Described sensitive switch is arranged on the sensitive switch frame, also be provided with slideway on the sensitive switch frame, the other end of connecting rod also connects and is arranged on the screw shaft that can slide in the slideway (7), is provided with connecting rod on the slideway limit and drives and can force it to sway when screw shaft is made linear slide to change the top board that angle bump sensitive switch makes it to move.
Can easily slide in slideway in order to allow connecting rod drive screw shaft, and the angle that top board is swayed is controlled in the scope that needs, screw shaft is provided with the roller of the diameter dimension that meets the requirements.
This high-tension fuse bump interlock has used on the high-voltage capacitor of controlling running current with high-tension fuse short-circuit protection and electric mechanical switch (contactor), reactor combination sideboard.Each parts is easy to assembly, and the device versatility is good, can install arbitrarily with high-tension fuse, can realize the safeguard protection of three-phase major loop operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, a kind of high-tension fuse bump interlock comprises crash panel 1, insulation bull stick 2, connecting rod 3 and sensitive switch 4, and crash panel 1 is connected with insulation bull stick 2 and is fixed on the fixed support 5, and an end of insulation bull stick 2 is connected with connecting rod 3.
Described sensitive switch 4 is arranged on the sensitive switch frame 6, also be provided with slideway 7 on the sensitive switch frame 6, the other end connection of connecting rod 3 is arranged on the screw shaft 10 that can slide in the slideway (7), roller 9 is loaded on the screw shaft 10, be provided with connecting rod 3 on slideway 7 limits and drive screw shaft 10 slips, roller 9 is rotated and displacements, force top board 8 to turn over an angle, promote sensitive switch 4 actions, provide cut-off signal and carry out disjunction.
With insulation on the bull stick 2 fixed support 5 and sensitive switch support 6 fixing after, when the major loop of three-phase alternating current when wherein certain short trouble occurs mutually, by this phase fuse fusible core that is contained in the loop its short circuit current is disconnected, the rapid crash panel 1 on the bump high-tension fuse bump interlock insulation bull stick 2 of the striker of top opening on this phase fuse simultaneously, insulation bull stick 2 is rotated, drivening rod 3, connecting rod 3 drives screw shaft 10 again and slides, the roller that is loaded on the screw shaft 10 9 is rotated and do straight-line displacement along slideway 7, force top board 8 to turn over an angle, promote sensitive switch 4 actions and provide instruction, the electric mechanical switch of control major loop operating current is moved rapidly, cut off the electric current of all the other two-phases, thereby the situation that prevents phase-deficient operation occurs.
This high-tension fuse bump interlock has used on the high-voltage capacitor of controlling running current with high-tension fuse short-circuit protection and electric mechanical switch (contactor), reactor combination sideboard.Each parts is easy to assembly, and the device versatility is good, can install arbitrarily with high-tension fuse, can realize the safeguard protection of three-phase major loop operation.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
Claims (2)
1. a high-tension fuse clashes into interlock, it is characterized in that comprising crash panel (1), insulation bull stick (2), connecting rod (3) and sensitive switch (4), crash panel (1) is connected with an end of insulation bull stick (2) and is fixed on the fixed support (5), and the other end of insulation bull stick (2) is connected with connecting rod (3); Described sensitive switch (4) is arranged on the sensitive switch frame (6), also be provided with slideway (7) on the sensitive switch frame (6), the other end of connecting rod (3) also is connected with the screw shaft (10) that can slide in slideway (7), be provided with connecting rod (3) on slideway (7) limit and drive screw shaft (10) can force its change angle bump sensitive switch (4) that sways to make it to move when making linear slide top board (8).
