Abstract

The utility model relates to a convenient intelligent air circuit breaker, which comprises a circuit breaker box body. One face of the circuit breaker box body is provided with a panel; the panel is respectively provided with a reset button, a closing button, a closing and opening indicator, an opening button, an energy storage and energy release indicator, and an energy storage handle groove; a manual energy storage handle, an in-out device and wiring terminals are hinged inside the groove; one side of the circuit breaker box body is provided with a backplane; a copper bar wiring terminal is fixedly arranged on the backplane via two fixing pieces; two integratedly-manufactured connection pieces which are parallel in a spacing mode form the copper bar wiring terminal; connection through holes are correspondingly arranged on the upper and the lower connection pieces; the top end of the manual energy storage handle is hinged with a handle via a hinge shaft; and the handle is bent inwardly to be embedded inside the groove of the handle. According to the convenient intelligent air circuit breaker, the contact area of the wiring terminal is doubled, resistance is reduced and heat loss is reduced as the conductive area is increased, and the wasted electric energy during the transmission process can be effectively reduced.

Description

Portable type intelligent universal circuit breaker

Technical field

The utility model belongs to field of circuit breakers, especially a kind of portable type intelligent universal circuit breaker.

Background technology

At present, known intelligent universal circuit breaker is comprised of parts such as shell, contact system, arc quenching system, upper and lower pedestal, operating mechanism, motor, manual transmission, current transformer, Intelligent tripping device, auxiliary switch, secondary inserting piece decompression, shunt releases.Main contact material is alloy are-tight, anti-weldering, and for improving the electrodynamical stability of contact system, contact system is by multi-channel parallel.In operating mechanism, adopt the free tripping mechanism of Si Even bar Bian Wu Even bar, for meeting the intelligent needs of controlling, mechanism need be designed to pre-energy storage pattern, in circuit breaker use procedure, mechanism is always in pre-energy storage position, as long as circuit breaker one is received the order of closing a floodgate, circuit breaker is instantaneous closure immediately just, and the release of pre-energy storage can button or release energy electromagnet and complete with manually releasing.

According to the retrieval, find the following patent documentation about intelligent universal circuit breaker, its Patent Literature CN1832083 discloses a kind of intelligent universal circuit breaker, Up Highway UHW copper bar, centre bore through current transformer, the secondary coil output signal of current transformer connects computer, moving contact, the fixed contact of netted or planar band ventilating microhole, Down Highway row forms the mechanical operating mechanisms such as general supply closed-loop path and electricity Qi Even connects, it is characterized in that: the fixed contact that is welded with netted planar band ventilating microhole, on hollow, copper bus-bar is through the centre bore of current transformer, be welded with copper bus-bar under the hollow of fixed contact of netted or planar band ventilating microhole, the flexible dielectric substrate of moving contact copper bus-bar is housed, fulcrum band bearing and the support of bearing on lever, lever lower fulcrum, sieve silk, the energy storage mechanisms that spring forms etc. form electric power loop.

The technical scheme of above-mentioned patent and the application's difference are larger, can not realize the application's object, solve the application's technical problem, larger with the application's difference.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of contact area large, save the energy, portable type intelligent universal circuit breaker easy to assembly.

The technical scheme that the utility model is realized object is as follows:

A kind of energy-conservation intelligent universal circuit breaker, comprise circuit breaker case, an installation panel of circuit breaker case, reset button is installed respectively on panel, switch knob, the indication of combined floodgate separating brake, opening button, energy storage is released and can be indicated, energy storage handle groove, in groove, hinge fills manual energy storage handle, in-out apparatus, binding post, a side at circuit breaker case is installed backboard, on backboard, by two stators, be fixedly mounted with copper bar binding post, it is characterized in that: described copper bar binding post is comprised of the brace of integrally formed two spaced and parallel, on upper and lower two braces, correspondence is shaped with connecting through hole, the top of described manual energy storage handle is by filling a joint handle compared with axle hinge, handle bends inwards and embeds in the groove of handle.

And described connecting through hole is four.

The beneficial effects of the utility model are:

The binding post of the portable type intelligent universal circuit breaker that 1, the utility model provides is comprised of the brace of integrally formed two spaced and parallel, integral body is scissors-type, during connection, the binding post being connected is directly inserted in the middle of brace, screw down, connect laborsavingly, save time, reduce energy consumption.

2, the utility model provides the contact area of the binding post of portable type energy type omnipotent breaker to increase by a generation, after conductive area increases, and resistance decreasing, thermal loss diminishes, and effectively transmits the electric energy of wasting in overshoot.

3, the utility model provides the top of manual energy storage handle of portable type energy type omnipotent breaker by filling a joint handle compared with axle hinge, has increased so the firmly length of handle, has increased moment, reduced to press down be firmly, make circuit breaker be more prone to operation.

Embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.

A kind of energy-conservation intelligent universal circuit breaker, comprise circuit breaker case 1, an installation panel 3 of circuit breaker case, reset button 11 is installed respectively on panel, switch knob 4, combined floodgate separating brake indication 10, opening button 8, energy storage is released and can be indicated 9, energy storage handle groove 5, in groove, hinge fills manual energy storage handle 6, in-out apparatus 12, binding post 2, a side at circuit breaker case is installed backboard 13, on backboard, by two stators 14, be fixedly mounted with copper bar binding post 16, circuit breaker case is that all kinds circuit breaker case that prior art exists all can, the application's innovation has two places, the first is about the improvement of copper bar binding post, it two is improvement about manual energy storage handle, concrete improved narration is as follows:

1, described copper bar binding post is comprised of the brace 15 of integrally formed two spaced and parallel, and on upper and lower two braces, correspondence is shaped with four connecting through holes 17.

2, the top of described manual energy storage handle is by filling a joint handle 19 compared with axle 18 hinges, and handle bends inwards and embeds in the groove of handle, has increased so the firmly length of handle, has increased moment, has reduced, to pressing down exerting oneself of being, to make circuit breaker be more prone to operation.

The structure of circuit breaker case inside is identical with the internal structure of intelligent universal circuit breaker of the prior art, the application does not do the architecture advances of circuit breaker case inside, emphasis is to improve copper bar binding post, therefore the structure of circuit breaker case inside is no longer described in detail.
