Description
Technical field
The utility model relates to a kind of double power supply automatic transfer switch, particularly a kind of CB level double power supply automatic transfer switch.
Background technology
The automatic turn-off of duplicate supply closes and is widely used in some and does not allow the place (as fire-fighting, airport, radio and television, hospital, market, bank, chemical industry, metallurgy, skyscraper and military equipment etc.) that cuts off the power supply.China's national standard and IEC standard are divided into PC level and two ranks of CB level with double power supply automatic transfer switch.PC level double power supply automatic transfer switch is merely able to disjunction and connects load, does not possess short circuit and excess current protective function, the general PC level double power supply automatic transfer switch protection component (as circuit breaker) that needs to increase electric power in distribution line.CB level double power supply automatic transfer switch main body by two open circuit, controlling organization and operating mechanism form; unusual (the outage of controlling organization in can testing circuit; short circuit etc.); and close a floodgate according to the separating brake that unusual condition control operation mechanism finishes circuit breaker; thereby have short circuit and excess current protective function, so function is more comprehensive.
The double power supply automatic transfer switch subminaturization is the main developing direction in this field of present stage, realize that the subminiaturized key of the automatic conversion of duplicate supply is the miniaturization of operating mechanism, present operating mechanism comprises electromagnetic type and single electric motor type, single motor double-acting power unit has " dial-slide plate bidirectional operating mechanism " at present, and " dial-fork double-acting power unit " reaches " gear-slide plate bidirectional operating mechanism ".Because parts such as dial, fork, gear, slide plate are subjected to structural limitations, size is bigger, and parts are various, is difficult to realize the subminaturization of operating mechanism.
The utility model of the patent No. 02289463.2 " double power supply automatic transfer switch " discloses a kind of small-sized double power supply automatic transfer switch, this device is provided with swing arm on motor output shaft, the circuit breaker handle transmission of driving lever and both sides is arranged in the swing arm, reach the purpose of separating brake and combined floodgate.Though this duplicate supply control switch structure is fairly simple, and motor control component is not set, when separating brake or combined floodgate were finished, motor can't cut out.Because the distance of swing arm is bigger, and mechanism reliability is not high, when concrete the use, break down easily in addition, install also more complicated.In addition, circuit breaker in the past is fixed in the draw-in groove on chassis, and more complicated is installed, and also is unfavorable for the compactness of mechanism.
Summary of the invention
The utility model provides a kind of volume small and exquisite in order to overcome the defective of prior art, compact conformation, and the reliability height, easy for installation and can stop the novel duplicate-power control switch of motor automatically.
In order to realize above purpose, the double power supply automatic transfer switch of the utility model design, comprise controlling organization, operating mechanism, circuit breaker commonly used and back-up breaker, circuit breaker commonly used and back-up breaker are arranged on the operating mechanism left and right sides, described operating mechanism comprises motor, dial, action bars, dial is connected with the output shaft of motor, there are two pairs of driving levers to be arranged on dial the right and left perpendicular to the dial plane, two action bars are fixedlyed connected with the back-up breaker handle with circuit breaker handle commonly used respectively, one end of action bars stretches into respectively between the corresponding a pair of driving lever, also be provided with the gag lever post vertical on the dial, the corresponding motor sensitive switch that is provided with gag lever post with the dial plane.
More than the beneficial effect of She Zhiing is: the output shaft by motor rotates the drive dial, the driving lever touching also drives action bars, because action bars is fixedlyed connected with circuit breaker handle, therefore thereby action bars drives circuit breaker handle and finishes the action that opens and closes lock, when the gag lever post on the dial reaches switching lock precalculated position at action bars, just in time touch the motor sensitive switch, send signal and stop motor.When the separating brake axle of dial one end drove breaker open operation, the combined floodgate axle of the other end will drive breaker closing, can guarantee the timely switching of power supply like this, also makes the two-way power supply can not connect simultaneously.Such mechanism is with respect to swing arm and circuit breaker transmission, compact conformation, and reliability is higher, and mechanism is simple, and part is few, thereby can accomplish that volume is small and exquisite.The while gag lever post cooperates with the motor sensitive switch, has also well solved original technology when finishing separating brake or closing a floodgate, automatically the problem of disable motor.
Further setting of the present utility model, described dial is made of last dial and following dial, and the two pairs of driving levers are arranged on up and down between the dial, and two ends are connected with dial up and down respectively, about an end of action bars stretches between the dial.Such setting is for fixing driving lever, makes driving lever be difficult for distortion in transmission process.Therefore gag lever post is arranged on down under the dial owing to will cooperate with the motor sensitive switch.
Further setting more of the present utility model, a side of described circuit breaker commonly used and back-up breaker is close to the operating mechanism shell, and opposite side is provided with clamping plate.Clamping plate are fastening by the long screw that runs through circuit breaker, and the long screw end is fixed in the operating mechanism shell, fix with respect to traditional groove, and the mode fixed structure of clamping plate is simple, and the tightness height between circuit breaker and the operating mechanism installs also more convenient.
Further setting of the present utility model, the input and the output of circuit breaker commonly used and back-up breaker are coated with the arc cover.This is provided with in order to intercept electric arc, increases the device coefficient of safety.
Further setting more of the present utility model, there is square insulation crust to cover controlling organization end face and side, the insulation crust end face is provided with axis hole, motor output shaft stretches out insulation crust by axis hole and is connected with a manual turntable, the top of circuit breaker also is provided with square insulation crust, and the insulation crust at circuit breaker top is connected with the arc cover of circuit breaker side.This insulation crust not only has insulating effect, also plays the effect of an integral component simultaneously, can only need to connect the structure between each module when mounted with parts respectively by module production when producing, and makes easier for installation like this.Can also use the manual turntable drive motor output shaft at top to open a sluice gate or close lock when needed.
The utility model is described in further detail below in conjunction with accompanying drawing.
