Abstract
The utility model discloses a closing degree indicating device of an outdoor alternating-current high-voltage isolator. The closing degree indicating device comprises a moving contact indicating signboard (1) and an insulating base indicating signboard (2), wherein the moving contact indicating signboard (1) is fixedly installed on the side of a moving contact (3) of the high-voltage isolator, perpendicular to a copper arm (4) of the moving contact (3) and rotates along with the moving contact (3); and the insulating base indicating signboard (2) is obliquely arranged at a silicone rubber skirt (6) of a high-voltage isolator insulating base (5), and when the moving contact (3) of the high-voltage isolator switches in place, the moving contact indicating signboard (1) rotates to be in the same straight line with the insulating base indicating signboard (2). By means of the closing degree indicating device, the contact area of moving and fixed contacts of a switch blade can be enlarged, the contact resistance is reduced, potential risks of switch blades are restrained effectively, and the improvement cost is quite low.
Description
Technical field
The utility model relates to a kind of combined floodgate degree indicating device of outdoor AC high-voltage isolating switch.
Background technology
24kV outdoor AC high-voltage isolating switch is very important device for switching in the medium-voltage distribution circuit, generally form and the medium voltage breaker with both sides plug-in strip or one-sided plug-in strip supports the use, its major function is: guarantee medium-voltage distribution equipment and the safety of device when service work, play isolation voltage, can not with cut off, drop into load current and cut-off short circuit current, only can be used for not producing some handover operation of powerful electric arc, that is to say that it does not have arc-suppression function.The use of plug-in strip forms obvious fracture and live part isolation while having guaranteed the controller switching equipment maintenance, due to isolating switch do not have arc-control device and connecting-disconnecting function low, so during disconnecting switch operation, must observe order, while being power transmission, the bus bar side of at first closing isolating switch, next line side isolating switch that closes, the circuit breaker that finally closes, have a power failure in above-mentioned contrary.The general structure of 24kV outdoor AC isolation switch, its electric connecting member is as follows: form fixed contact by a curved rectangular copper coin, its porose end can be connected with bus by screw; The other end is shorter, and during combined floodgate, it contacts with cutting blade (moving contact).Article two, copper coin forms bow strip, be called again moving contact, certain angle can rotate around the axis, during combined floodgate, it clamps fixed contact, in actual motion, whether 24kV outdoor AC isolation switch combined floodgate puts in place, and (exposure level that directly affects moving contact and fixed contact) there is certain impact in safe operation for distribution line, during the plug-in strip operation, do not get togather fully, medium voltage breaker, plug-in strip charging operation close in the situation not in place of closing a floodgate.Now moving contact and fixed contact contact position repulsion are very large, and its contact area is inadequate, and the edge of a knife closes not sternly, causes surface oxidation, and contact resistance is increased, and line load is overweight in addition, according to Q=I
2* R, now can cause the contact portion temperature very high, and long-time running is at so high temperature, and the plug-in strip that is not incorporated into position just becomes the operating hidden danger point of circuit, tends to cause more serious consequence.
Summary of the invention
The utility model provides a kind of combined floodgate degree indicating device of outdoor AC high-voltage isolating switch, and it can be so that the contact area of plug-in strip dynamic/static contact increases, and contact resistance reduces, and has effectively contained the potential safety hazard of guillotine kind, and improvement cost is very low.
The utility model has adopted following technical scheme: a kind of combined floodgate degree indicating device of outdoor AC high-voltage isolating switch, it comprises moving contact indicating signboard and insulating base indicating signboard, the moving contact indicating signboard is fixedly mounted on the moving contact side of high voltage isolator, the moving contact indicating signboard is vertical with the copper arm of moving contact, the moving contact indicating signboard is along with the rotation of moving contact, the insulating base indicating signboard is positioned on the silicon rubber shirt rim of high voltage isolation switch insulating pedestal and is inclined to set, when the moving contact switching of high voltage isolator puts in place, the moving contact indicating signboard turns to the insulating base indicating signboard on same straight line.
Described moving contact indicating signboard is silicane rubber plate, and the moving contact indicating signboard is arrow shaped.Described insulating base direction board is silicane rubber plate, and the insulating base direction board is arrow shaped.
The utlity model has following beneficial effect: after having adopted above technical scheme, the utility model can to plug-in strip whether close a floodgate put in place carry out one as seen, distinguishing rule intuitively, indicating gage puts in place and means that the plug-in strip combined floodgate puts in place, thereby make the contact area of plug-in strip dynamic/static contact increase, contact resistance reduces, the potential safety hazard of effectively having contained guillotine kind, " combined floodgate degree " indicating gage principle is simple simultaneously, for existing plug-in strip, change very little, improvement cost is very low, suits large area to popularize.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
