Description
Technical field
The utility model relates to a kind of switchgear, relates in particular to a kind of switchgear with electronic propelling handcart.
Background technology
When switchgear is prepared to put into operation, after handcart need push in cabinet from switch cubicle, move to service position from test position again, this process will overcome the handcart self gravitation, the frictional force of handcart wheel or directive wheel and track, and the effect of the resistances such as frictional force when on handcart, moving contact and switch cubicle upper static contact are pegged graft, for the safe distance of operating personnel and live part, consider simultaneously, directly shift handcart onto service position from test position by the people and both difficultly also had potential safety hazard, thereby the special propulsive mechanism cooperatively interacted must be set in handcart and switch cubicle, shaking handle by operating personnel realizes the propelling of handcart or exits.
The handcart that in existing switchgear, configuration manually advances usually, the location fixture block that comprises handcart, is loaded on the worm-and-wheel gear on handcart and is loaded on the switch cubicle both sides, after handcart pushes switch cubicle from cabinet, the location connecting lever that coaxially is connected with worm gear and stretches out the handcart two ends snaps in the location fixture block that is loaded on the switch cubicle both sides, now shaking a hand drive worm screw rotates, thereby driving handcart moves forward until service position, when handcart need to exit, shake a hand drive worm screw in the other direction and rotate, can drive handcart and move backward until test position.
In existing switchgear, the propelling of handcart is still realized by manpower, or handcart that capacity larger higher for electric pressure, need overcome larger resistance, harder during operation.And must be advanced and retreat in switchgear erecting bed handcart operation of operating personnel, both there is potential safety hazard, simultaneously because not realizing Long-distance Control, also restricted the development of Automation System of Power Network and unattended substation.
The utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is improved prior art, a kind of switchgear with electronic propelling handcart is provided, solve the handcart of switchgear in current technology by manual feed, can't realize the problem of automation and Long-distance Control.
For solving above technical problem, the technical solution of the utility model is:
A kind of switchgear with electronic propelling handcart, it is characterized in that, comprise switch cubicle, handcart, motor drive mechanism and transmission mechanism, described handcart is pushed in switch cubicle and is connected with transmission mechanism, motor drive mechanism passes through the transmission mechanism transferring power to handcart, transmission mechanism converts the rotary power of motor drive mechanism between the test position of axial thrust push-and-pull handcart in cabinet and service position to and moves, to realize the conversion of primary conductive loop between isolation/open position and work/on-position of handcart, safety labor-saving, and can realize far distance controlled, meet the miniaturization of modern power network to switch cubicle, automation, the requirement of high reliability, be applicable to Automation System of Power Network and unwatched transformer station.
Further, transmission mechanism adopts the screw mandrel propulsive mechanism to carry out transmission, on the screw mandrel propulsive mechanism, cover has hooked scarf, the screw mandrel propulsive mechanism is connected with motor drive mechanism by joint, motor drive mechanism drives screw mandrel propulsive mechanism radial rotary, hooked scarf does not rotate, and by screw thread, is driven along the axial advancement of screw mandrel propulsive mechanism and is retreated.Adopt the screw mandrel propulsive mechanism can realize that axial low speed advances, avoid excessive velocities that destruction equipment occurs to collide, the screw mandrel propulsive mechanism can also be realized intermittently pausing simultaneously, if any emergency, occur, disable motor rapidly, handcart stops advancing at once, safe and reliable, can offer the sufficient crash time of people.The transfers great efforts of screw mandrel propulsive mechanism, can promote heavy handcart very easily, saves the energy that drives handcart, flexible.
Further, be provided with location-plate on handcart, location-plate is connected with the mode of hooked scarf by engaging, and hooked scarf drives handcart along the axial advancement of screw mandrel propulsive mechanism and retreats.Handcart in being pushed into switch cubicle after, be fixed by location-plate and hooked scarf, thereby drive motion vertically by the screw mandrel propulsive mechanism; When needs are safeguarded handcart, untie location-plate and handcart can be pulled out to switch cubicle with engaging of hooked scarf, avoid insufficient light in switch cubicle, space is also not enough, to maintenance, brings inconvenience.
Further, the screw mandrel propulsive mechanism also is provided with crank for manually advancing handcart.When because of reasons such as power failures, needing the manual operation handcart to advance, can realize that the door-closing operation handcart is from the test position to the service position, the potential safety hazard of having avoided opening door operation to bring, simple to operation, flexibility and reliability.
Compared with prior art, the utility model advantage is:
Switchgear with electronic propelling handcart described in the utility model drives the screw mandrel propulsive mechanism by motor drive mechanism and realizes the electronic propelling of handcart or exit, safety labor-saving, and can realize far distance controlled, meet the requirement of modern power network to the miniaturization of switch cubicle, automation, high reliability, be applicable to Automation System of Power Network and unattended substation; Propulsive mechanism is the screw mandrel propulsive mechanism, and the transfers great efforts can easily promote handcart, also is equipped with crank to advance by manual operator car under the situations such as power failure, the potential safety hazard of having avoided opening door operation to bring simultaneously; The utility model is simple in structure, is easy to realize, and flexible and convenient operation, safe, low cost of manufacture.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
The disclosed a kind of switchgear with electronic propelling handcart of the utility model embodiment, take that the handcart of realizing switchgear advances automatically, Long-distance Control is purpose.
Referring to Fig. 1, a kind of switchgear with electronic propelling handcart, comprise switch cubicle 1, handcart 2, motor drive mechanism 8 and transmission mechanism, handcart is pushed in switch cubicle and is connected with transmission mechanism, motor drive mechanism 8 passes through the transmission mechanism transferring power to handcart 2, transmission mechanism converts the rotary power of motor drive mechanism 8 between the test position of axial thrust push-and-pull handcart 2 in cabinet and service position to and moves, to realize the conversion of primary conductive loop between isolation/open position and work/on-position of handcart.
