Description

The mid-board breaker handcart of a kind of 40.5kV advances the work-saving device of pulling out

Technical field

The utility model relates to electrical equipment technical field, is specifically related to the mid-board breaker handcart of a kind of 40.5kV and advances the work-saving device of pulling out.

Background technology

40.5kV mid-cabinet is because volume is little, and handcart is in light weight, interlocking is reliable, to installing that the basis requires advantage such as low and the welcome that receives power consumer.The same with the mid-cabinet of 12kV, the circuit breaker cart of the mid-cabinet of 40.5kV need be used transfer car(buggy) at the push-on switch cabinet or when pulling out switch cubicle, with after switch cubicle docks good position, needs to use manpower that circuit breaker cart is advanced or pulls out at transfer car(buggy).At first the handle on the chassis is inwardly pushed away during operation; Overcoming spring force contracts to the chassis latch; Untie the interlocking of handcart and switch cubicle, promote or spur handcart then and just can make circuit breaker cart slide on the track in the switch cubicle or motion in the other direction from transfer car(buggy).Because the circuit breaker cart width of the mid-cabinet of 40.5kV has 1040mm, the degree of depth has 927mm, and a people can't accomplish this operation at all, must about each people operation of making a concerted effort; And hand will inwardly push away handle overcome spring force, and the another hand will promote or spur handcart, should about firmly; Firmly, good teamwork could be accomplished smoothly again; Not only effort also than higher, impacts for wideling popularize of this switch cubicle to operating personnel's requirement very much.

The utility model content

The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, provides the mid-board breaker handcart of a kind of 40.5kV to advance the work-saving device of pulling out, and this circuit breaker cart should have convenient for unlocking, characteristic of simple structure, to reduce work personnel intensity.

For realizing above purpose, the technical scheme below the utility model has adopted:

The mid-board breaker handcart of a kind of 40.5kV advances the work-saving device of pulling out; Comprise a circuit breaker car body; The rear portion, chassis of said circuit breaker car body is provided with the interlocking device that is used for the switch cubicle interlocking; This interlocking device comprises that two groups receive the latch of stage clip roof pressure to give prominence to the circuit breaker car body left and right sides respectively, and spurs two handles that said two groups of latches shrink to body inner side respectively, and the opening of two handles is all arranged down; It is characterized in that: said circuit breaker cart also disposes a mechanical brake, and the rear end on said chassis is provided with two jacks that are used to install mechanical brake, and it is the most inboard that two jacks lay respectively at the movement locus of two handle openings.

Said mechanical brake adopts iron wire to make, and the right ends of iron wire bends respectively and is useful on the quarter bend that inserts said jack.

The operation principle of the utility model is: with after switch cubicle docks good position, operating personnel can all inwardly move two draw rings to final position, then the two ends of mechanical brake are inserted in two jacks at transfer car(buggy).This moment, the quarter bend of mechanical brake can catch on two handles, offset the active force of stage clip, prevented that two groups of latches from moving laterally, realized the release of circuit breaker cart, afterwards operating personnel can be like a cork with its propelling or pull out switch cubicle.When needs are interlocked with switch cubicle, only need mechanical brake is pulled up, two groups of latches reset and get final product.

The beneficial effect of the utility model is: the utility model is through a mechanical brake, and the interlocking device of circuit breaker cart is remained on unlocked position, and operating personnel only need push away or pull back circuit breaker cart forward; Need not two people and respectively operate a handle, very laborsaving, reduced labor intensity of operating personnel; And it is simple in structure; Easy to use, with low cost, the large tracts of land that helps the mid-cabinet of 40.5kV is promoted.

Embodiment

Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.

As shown in Figure 1; The mid-board breaker handcart of the described a kind of 40.5kV of the utility model advances the work-saving device of pulling out; Comprise a circuit breaker car body 1 (this body construction and conventional circuit breaker car body are similar); 4 rear portions, chassis of said circuit breaker car body are provided with the interlocking device that is used for the switch cubicle interlocking, and this interlocking device comprises two groups of latches 3 (every group comprises one or more latches, is 2 among the figure), two stage clips and two handles 2; Said two groups of latches are installed in the left and right sides at rear portion, chassis respectively, and outstanding with interlock with switch cubicle (promptly outstanding outside car body) to circuit breaker car body left side and right side respectively under the roof pressure of stage clip; Said two handles are connected with two groups of latches respectively, shrink towards body inner side to spur two groups of latches, and direction realizes the release of circuit breaker hand and switch cubicle shown in arrow among Fig. 1.The opening of two handles is all arranged down, is shaped on the chute of said handle on the chassis in addition, and is clean and tidy for making drawing, omits among the figure and do not draw.

Said structure is all similar with conventional circuit breaker cart, and in order to solve the topic that is of release difficulty, the utility model has been made following improvement.

The utility model disposes a mechanical brake 5 on the chassis of said circuit breaker, said mechanical brake adopts iron wire to make, and the right ends of iron wire has bent quarter bend 5-1 respectively.It is the most inboard that the rear end on said chassis is shaped on the movement locus that two jack 6, two jacks that are used to install mechanical brake lay respectively at two handle openings.Operating personnel are drawn to two handles after the inboard; Can the quarter bend of mechanical brake be inserted in the jack of two correspondences, because the right angle plug insertion position is positioned at the opening of two handles, so quarter bend can be offset the active force of stage clip; Prevent that handle from resetting, and realizes the release of latch.When circuit breaker cart need be interlocked, only need mechanical brake is taken off, handle can drive latch and reset under the effect of stage clip, realize interlocking.

For making drawing clean and tidy, stage clip omits and does not draw among the figure.
