Abstract
The utility model relates to an electric closing device for a guide rod breaker, which is composed of an electric control circuit and a mechanical operating mechanism. A motor is connected with a screw rod; the outer screw of the screw rod is matched with the inner screw of a slide block; the slide block is connected with a handle of a knife switch; the motor and the screw rod are fixed on a support frame; an upper and a lower stroke switches are at the easy contacting points of both ends end points of the stroke of the slide block or the knife switch; a polished rod and the screw rod are parallel arranged on the support frame; the slide block is sheathed on the screw rod and the polished rod. The utility model is suitable for the electric apparatus with electric switches of air switches and electrical leakage breakers; the utility model has the advantages that the slippage of the slide block is smooth and straight, and the clamping can not exist when he knife switch is closed and pulled apart.
Description
The utility model relates to the electric switch of a kind of air switch, residual current circuit breaker automatic closing.
Qianlong Electric Appliance Co., Ltd., Lin-an, Hongzhou had once applied for " electric switch-on device of breaker " patent, application number is 00208566.6, the model machine analysis that patented technology from the said firm applies for it is produced, can solve air switch, the automatic closing problem of residual current circuit breaker, but because this technology is to use motor after slowing down, be connected with screw mandrel, be with the slide block that internal thread cooperates with the external screw thread of this screw mandrel on the screw mandrel, slide block connects the handle of air switch, the rotation of driven by motor screw mandrel, screw mandrel drives slide block and makes line sliding, just spurs the handle action, the motor forward or reverse, handle just closes a floodgate or operates a switch.What this structure was slightly felt deficiency is that slide block easily rocks in sliding, and very end is straight for track, and the handle that it involves in closing a floodgate, operating a switch, probably has the worry of clip.
The purpose of this utility model is to increase on the basis of the above guide post, change some corresponding constructions, the purpose that can effectively reach automatic closing, operate a switch not only, slide block is not rocked in sliding, the running orbit end is straight, the combined floodgate of the handle that slide block affects, do not have the worry of clip when operating a switch, meet the standard of zero tolerance.
The purpose of this utility model can realize by following measure: it is made up of electric control circuit and the mechanical handling two large divisions of mechanism, the projecting shaft of motor connects screw mandrel behind deceleration device, the external screw thread of screw mandrel matches with the interior spiral shell strand of slide block, slide block links to each other with the handle of plug-in strip, motor and screw mandrel are fixed on the support, upper and lower stroke switch is fixed on easy touching place of the terminal point at slide block or plug-in strip stroke two ends, and polished rod and screw mandrel are installed in parallel on the support, and the slide block chuck is on screw mandrel and polished rod.
Fig. 1 is the utility model structural representation.
Fig. 2 is electrically connected block diagram for the utility model.
Fig. 3 is electric control circuit figure.
The utility model is described in detail below in conjunction with accompanying drawing: whole device is made up of electric control circuit and the mechanical handling two large divisions of mechanism, its mechanical part is that motor 1 links to each other with screw mandrel 2 through reducing gear, should, screw mandrel 2 cooperates with slide block 5, makes the deceleration of sliding of slide block also possess certain effect.There is bearing screw mandrel 2 ends, the screw-internal thread fit of the external screw thread of screw mandrel 2 and slide block 5, slide block 5 links to each other with the handle 4 of plug-in strip, slide block 5 chucks are on two screw mandrels parallel to each other 2 and polished rod 3, " chuck " described here, three kinds of modes can be arranged: slide block is recessed into half slot in 5 both sides, is clipped between two bars 2 and 3; Slide block 5 one side grooves are stuck in wherein on the bar (polished rod or screw mandrel), and slide block 5 has a hole in addition, is enclosed within on another bar; Slide block 5 diplopores are enclosed within respectively on polished rod and the screw mandrel.Motor 1, screw mandrel 2, polished rod 3 all are fixed on the support 6.Upper and lower stroke switch is fixed on easy touching place at slide block 5 or plug-in strip stroke two ends.
Shown in Figure 2 is electrically connected in the block diagram, electrical apparatus control circuit B is behind the reclosing command of receiving signal input part XH input, reverse pumping goes out reverse electrical source to motor 1, motor 1 drives screw mandrel 2 counter-rotatings, make and be stuck in the slide block 5 drive male contact handles 4 that the other internal thread of screw mandrel 2 sides cooperates with this screw mandrel 2 and move to the direction that resets, carry out reset operation, when slide block 5 or plug-in strip move to the touching lower stroke switch, latter's output resets and finishes signal, and this signal is defeated by electric control circuit B, make B output be rotated in the forward power supply and give motor 1, motor 1 just drives screw mandrel 2 commutation rotations, slide block 5 and coupled male contact handle 4 also move to opposite (combined floodgate) direction, and up to combined floodgate, this moment, upper stroke switch was touched, finish signal to electric control circuit B output combined floodgate, B just instructs and is rotated in the forward power supply and stops to motor 1 power supply, motor 1, screw mandrel 2, slide block 5 threes all shut down, and whole closing operation program is finished.
The present residual current circuit breaker of producing is made the critical piece of break-make power supply with air switch, and therefore, for ease of understanding, the plug-in strip in the utility model can be with air switch as an example.Other parts and the structure of residual current circuit breaker are prior aries, do not give unnecessary details.
