Abstract
A double motor operating device of a breaker comprises motors (2), transmission gears (5), a tooth bar (7), a joint (10), two clamping rods (11), a slideway (8), a chute (9) and a slide rod (12). The two motors (2) are a pair of synchronous reversible motors with the same specification and model and are arranged side by side with the same horizontal height. Each motor is provided with one transmission gear (5) and the two transmission gears are arranged with the same horizontal height. The two transmission gears are respectively engaged with or separated from left and right teeth of the tooth bar (7). An upper fixing plate (1) is disposed between the transmission gears (5) and an upper side of the tooth bar (7), and a lower fixing plate (6) is disposed between the transmission gears (5) and a lower side of the tooth bar (7). A pair of mutually engaged hand-operated or electric conversion gears (3) is arranged on the upper fixing plate (1), and one of the conversion gears is provided with a turn button (4). The double motor operating device serves as a both electric and hand-operated operating mechanism that is suitable for a large plastic casing breaker with rated current higher than or equal to 800A. The advantages are that the double motor operating device is small in size, light in weight, low in cost and low in electricity consumption, and the height of the entire device accords with requirements.
Description
Technical field
The utility model relates to a kind of electrically operated device that is installed in the circuit breaker in the three-phase and four-line low-voltage circuit distribution box, especially by bi-motor drive, can be electronic after the tripping operation or the operating means of hand-reset.
Background technology
The deenergizing of in three-phase and four-line low-voltage circuit distribution box, installing, in recent years very fast in China's development, the residual current circuit breaker of especially various models, function is different from structure, and kind is a lot.Because family's standard has requirement to the interior height of distribution box, thereby placed restrictions on the height of circuit breaker.Be the large shell frame breaker of plastic casing of 800A if circuit breaker is a kind of rated current, being used as power with single motor routinely, then need dispose one 20 watts synchronous reversible motor, or join one 200 watts series machine, not only price is high, power consumption is many for these motors, volume is large, and the whole height of circuit breaker surpasses the interior height of distribution box, can't be installed in the case.
The utility model content
The technical problems to be solved in the utility model is to design a kind of bi-motor operating means of circuit breaker.
Solve this technical problem and adopt following technical scheme: the bi-motor operating means of this circuit breaker, comprise motor, travelling gear, there is the tooth bar of slide bar and chute the centre, the connector that connects tooth bar and handle, folder is toward two clamping bars of handle on the connector, the slideway of connector left and right sides, the slide bar in the chute of the left and right sides is inserted respectively at chute on the slideway and two ends, it is characterized in that motor is the identical a pair of synchronous reversible motors of specifications and models, the same level height is installed side by side, the travelling gear of respectively installing with a same level height, two travelling gears can mesh with the left and right tooth of same tooth bar respectively or separate as required, driving cog wheel and rack upper, there is respectively upper mounted plate and the bottom plate that covers in being fixed on the below, a pair of intermeshing manual or electric rotating gear changing is arranged on the upper mounted plate, on one of them this conversion gear knob is arranged, have below this conversion gear and its coaxial mounted cam of stirring the engagement of driving cog wheel and rack or separating.
Described bi-motor is that every power is the reversible electric machine of making a positive and a negative synchronous rotary of 5W.
Described travelling gear is the gear that two specifications and the number of teeth equate, do a positive and a negative synchronous rotary.
The beneficial effects of the utility model are for the circuit breaker of 800A, adopt two respectively for the synchronous reversible motor of 5W is used as power, surpass 800A, be used as power with summary two synchronous reversible motors higher than 5W, lightweight, inexpensive, power saving, the height of complete machine meet high standard requirement in the distribution box.

Embodiment
Structure embodiment and described in detail with reference to accompanying drawing below the utility model; Referring to Fig. 1 and Fig. 2, the bi-motor operating means of this circuit breaker, comprise motor 2, travelling gear 5, there is the tooth bar 7 of slide bar and chute the centre, the connector 10 that connects tooth bar 7 and handle 13, folder is toward two clamping bars 11 of handle on the connector, the slideway 8 of connector left and right sides, the slide bar 12 in the chute of the left and right sides is inserted respectively at chute 9 on the slideway and two ends, motor is the identical a pair of synchronous reversible motors 2 of specifications and models, the same level height is installed side by side, the travelling gear 5 of respectively installing with a same level height, two travelling gears can mesh with the left and right tooth of same tooth bar 7 respectively or separate as required, travelling gear 5 is upper with tooth bar 7, there is respectively upper mounted plate 1 and the bottom plate 6 that covers in being fixed on the below, a pair of intermeshing manual or electric rotating gear changing 3 is arranged on the upper mounted plate 1, knob 4 is arranged on this conversion gear, have below this conversion gear and its coaxial mounted cam of stirring travelling gear 5 and tooth bar 7 engagements or separating.
Described bi-motor is that every power is the reversible electric machine of making a positive and a negative synchronous rotary 2 of 5W.
Described travelling gear is the gear that two specifications and the number of teeth equate, do a positive and a negative synchronous rotary.Described a positive and a negative be one turn clockwise, a counterclockwise rotation.During the work of this device, press energize, motor 2 rotates, band nutating gear 5 rotates, thereby promotion tooth bar 7 seesaws, and under the acting in conjunction of connector 10, chute 9, slide bar 12, two clamping bars 11, push-and-pull the handle 13 that is clipped in 11 of two clamping bars and made the action that resets and close a floodgate.When circuit breaker trip cuts off the power supply, need electronic or hand-reset, then with knob 4 along or counter-clockwise direction turn manual and electric conversion gear 3, just the dialling and backwash of rotation cam coaxial mounted with it, make 7 engagements of travelling gear 5 and tooth bar or separate, realize respectively electronic or manual resetting and combined floodgate.
