Abstract
The utility model relates to an electromagnetic hydraulic circuit breaker which comprises a casing with the structure that a tripping device and a coil assembly are arranged in the casing, wherein the coil assembly comprises a hydraulic cylinder, coils are coated outside the hydraulic cylinder, resisting medium is filled in the hydraulic cylinder, an armature is arranged in the hydraulic cylinder, one end of the armature is provided with a reset spring, and a magnetic conductor is arranged outside the hydraulic cylinder at one side of the reset spring; simultaneously, a tripping buckle is arranged at the side of the tripping device near the magnetic conductor and the tripping device realizes tripping linkage through the action of the tripping buckle. The tripping protection of the utility model only concerns the current strength of the coil, therefore a circuit can be normally protected in a rapidly changing condition of temperature; simultaneously, through the adjustment of the degree of coherence of the resisting medium, the adjustment of the delay time of the contact of the armature with the magnetic conductor can be realized, namely the tripping delay time of the circuit breaker, and the tripping situation of the circuit breaker in the condition of instant wave current and voltage can be prevented; however, too much current is enough to cause the circuit breaker to trip instantly.
Description
Affiliated technical field
The utility model relates to a kind of electromagnetic hydraulic pressure circuit breaker.
Background technology
Existing circuit breaker adopts the structure of bimetal leaf mostly to the protection of overcurrent in the circuit, and this structure is subjected to the influence of ambient temperature very big, and when the variation of circuit breaker ambient temperature was bigger, the work of existing circuit breaker will be undesired.Simultaneously, the function of neither one deferred action when existing circuit breaker takes place at overcurrent, the electric current and voltage at circuit has under the condition of fluctuation like this, and misoperation usually takes place in existing circuit breaker.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of not temperature influence, the circuit breaker that has certain time-delay escape function simultaneously.
The utility model comprises housing, be provided with trip gear and coil assembly in the housing, wherein coil assembly comprises hydraulic cylinder, hydraulic cylinder coats coil outward, be full of resisting medium in the hydraulic cylinder, be provided with armature in the hydraulic cylinder, an end of armature is provided with back-moving spring, is provided with magnetic conductor outside the hydraulic cylinder that is positioned at back-moving spring one side; Simultaneously, trip gear is provided with the tripping operation button near magnetic conductor one side, and trip gear is realized the interlock of threading off by the action of tripping operation button.
The resistance that the utility model utilizes the armature in the coil drive hydraulic cylinder to overcome resisting medium and back-moving spring moves to magnetic conductor, when armature with the magnetic line of force major part in the armature is concentrated in the magnetic conductor after magnetic conductor contacts, thereby the tripping operation button in the trip gear is moved to magnetic conductor, make circuit breaker tripping.By the above-mentioned course of work as seen, dropout of the present utility model protection is only relevant with the current strength of coil, therefore, can be under temperature condition jumpy normal protective circuit.Simultaneously, the utility model can reach by the sticky limit adjustment to resisting medium adjusts the time of delay that armature contacts with magnetic conductor, i.e. the delay escape time of circuit breaker, prevent that circuit breaker escape situation takes place under transient fluctuation electric current and voltage conditions.But excessive electric current is enough to make circuit breaker moment escape.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of present embodiment
Embodiment
As shown in the figure, present embodiment comprises housing 1, be provided with trip gear and coil assembly in the housing 1, wherein coil assembly comprises hydraulic cylinder 21, the hydraulic cylinder 21 outer coils 22 that coat are full of resisting medium in the hydraulic cylinder 21, are provided with armature 23 in the hydraulic cylinder 21, be provided with back-moving spring 24 between one end of armature 23 and hydraulic cylinder 21 inwalls, outside the hydraulic cylinder 21 that is positioned at back-moving spring 24 1 sides, be provided with magnetic conductor 25.
Simultaneously, trip gear is provided with tripping operation button 31 near magnetic conductor 25 1 sides, and trip gear is realized the interlock of threading off by the action of tripping operation button 31; Wherein trip gear comprises handle 32, snap close 33, tripping 34, connecting plate 35, support 36, tripping operation plate 31, moving contact rack 37, moving contact 38 and fixed contact 39.Wherein, moving contact 38 is arranged on the moving contact rack 37, and fixed contact 39 is provided with on the housing 1 position corresponding with moving contact 38.
In this device, Handle axis 41 links together handle 32 and support 36, and handle spring 42 1 ends are stuck on the support 36, and the other end withstands on first axle 43, the power that generator dropout back handle 32 resets makes handle 32 make circular motion by thorny arbor 41 simultaneously.
Snap close 33 forms first hinge by first axle 43 with handle 32 and is connected, and connecting plate 35 is connected by second axle, 44 formation, second hinge with snap close 33,37 of moving contact racks form the 3rd hinge with connecting plate 35 by the 3rd axle 45 and are connected, and are provided with connecting plate spring 52 between moving contact rack 37 and the connecting plate 35.Tripping 34 then is hinged on the connecting plate 35 by the rivet 46 of semiaxis form, is provided with tripping spring 51 between tripping 34 and the connecting plate 35, and semiaxis rivet 46 partly leans with the pinning of snap close 33.Moving contact rack 37 is hinged by main shaft 47 and support 36, is provided with main spring 48 between moving contact rack 37 and the support 36.Tripping operation plate 31 is hinged with support 36 by the 4th axle 49, and the rear end of tripping operation plate 31 is provided with tripping operation sheet reset spring 50 near the movable end of tripping 34 between tripping operation plate 31 and the support 36.
The slight spring force of tripping spring 51 under normal circumstances reliably overlaps tripping 34 with snap close 33, connecting plate spring 52 can reset connecting plate 35 smoothly after the device tripping operation, main spring 48 not only provides dynamic and static contact 38,39 required pressure when making current, can make moving contact rack 37 jump out of fixed contact 39 fast after also making the device tripping operation, to quicken arc extinguishing.
Entire mechanism is put into housing after connecting into a reliable integral body by axle, rivet, spring again, by corresponding axle location hole on the housing entire mechanism is positioned in the housing.
Under shown position, when handle moves clockwise, because of the semiaxis of snap close and tripping is abutted together, make second articulated link chain by locked, order about moving contact rack and make clockwise circular motion around main shaft, all the other are formed the each several part of mechanism and also make corresponding sports, when dynamic and static contact contacts, just can make Handle axis and first, second and third hinge point-blank, then when handle is done motion more slightly, just can cross the mechanism dead point and make firm the combining of dynamic and static contact.When phenomenon of the failure, tripping is stirred in tripping operation button rear end makes tripping move counterclockwise around semiaxis, drives semiaxis simultaneously and moves counterclockwise, and the releasing tripping is connected with snap close, thereby the chain state of entire mechanism is removed.Moving contact rack motion counterclockwise makes moving contact break away from fixed contact, and handle is return under the drive of handle spring, drives snap close simultaneously and is back to the state as figure, and each assembly all is back to as figure state under the drive of respective springs power.
