Embodiment
Parts or element identical or same function indicate identical Reference numeral in the accompanying drawing.
Fig. 2 is for the erection unit 1 of electricity, be the schematic diagram of the housing of opening of line protection switch here.Between input terminal 9 and outlet terminal 10, current circuit at first along terminal board 29, be welded on the support end that is designed to the U-shaped arc 5 that first conductor segment 14 on this terminal board extends to supporting leg 4.The stiff end 3 of the strap 2 that is made of the thermo bimetal is welded on the free end 6 of supporting leg 4.The opposed free end 7 of thermo bimetal's strap 2 is connected with twisted wire 20.This twisted wire guides to the contact lever 17 that is supported on support zone 21 swingably with electric current, and the free end of contact lever has movably contact 18.This contact forms the contact site with static contact 19.Current circuit continues to stretch the circuit breaker 16 of process magnetic until outlet terminal 10 from static contact 19.The open position of contact lever 17 is shown with solid line among Fig. 2, is shown in broken lines its bonding station.At open position, this moment, the contact site disconnected, and movably contact 18 is positioned near the support end 5 of U-shaped arcuation.
If the electric current in the main current circuit is higher than rated current for a long time, it is so-called overcurrent, then thermo bimetal's strap 2 with the opposed free end of stiff end because the electric heating that causes by overcurrent and bending therein, thereby it affacts on the latching device 8 by position 22, and is responsible for making junction to thread off there.The reciprocation of thermo bimetal's strap and latching device 8 can adopt simple mode to realize, a kind of scheme wherein illustrates in described DE 10 2,008,006 863 A1.After junction is threaded off, switching mechanism affacts on the contact lever 17 by position 24, and make this contact lever swing clockwise, thereby movably contact 18 separates with static contact 19, and the contact site disconnects, and kept disconnecting by latching device 8, referring to contact lever 17 with the position shown in the solid line.
Realize connecting once more by shift knob 27, this shift knob passes through position 26 and latching device 8 mating reactions, and allows junction to be connected once more when touching, if thermo bimetal 2 is bent back to its initial position again after overcurrent disappears.13 couples of thermo bimetals 2 regulate by adjustment screw.This adjustment screw is supported in the fixing thread mechanism of unshowned here housing.The for example screw shell of thread mechanism can be injected on the medial surface of clamshell.Adjustment screw makes supporting leg 4 around its support end 5 swings.It changes the U-shaped opening between the supporting leg 4 and the first limit leg 32 thus.Because thermo bimetal's strap 2 is welded on the supporting leg 4 below, so the free stiff end 7 of the swing scalable thermo bimetal strap 2 by supporting leg 4 is at a distance of the spacing of latching device 8.
The current circuit if short circuit current, many times the electric current that promptly rises to rated current are in a short period of time flowed through, then magnetic circuit breaker 16 responds.This magnetic circuit breaker directly and apace strikes on the contact lever 17 by position 25 then, and it also affacts on the latching device 8 by position 23 simultaneously, disconnects so that realize the dropout of this latching device and keep in touch the position enduringly.
When clashing into the contact site apace, between the contact that motion is left mutually, produce switching arc.This switching arc commutated to static touch controls bus 30 after the short time, and commutated to electric arc control bus 12 by the first limit leg 32, and imported to the arc control device 15 that are used for arc extinguishing.As long as electric arc does not extinguish as yet, this electric arc just has short circuit current.This moment flow through first conductor segment 14, U-shaped support end 5, electric arc and static touch controls bus of short circuit current, until arc extinction.The U-shaped support end is the loop that stream has electric current.According to the utility model, in the position of the close removable contact 18 of support end, at the contact site gap, the effect of the U-shaped arc of support end is as big arc blow-out loop.At this, by U-shaped bending of the present utility model, strengthened electromagnetism arc blowing function to electric arc, this helps to make electric arc to enter into arc control device apace, and then helps electric arc to extinguish apace.
Electric arc control bus 12 has the projection of having mentioned 31 in its left side towards the contact site.This projection is approximately U-shaped, has: the first limit leg 32, and it directly is connected with electric arc control bus 12; With the second limit leg 4, it forms supporting leg 4, thereby is also referred to as supporting leg 4.The producing method of supporting leg 4 is: 31 support end that the is also referred to as crooked position 5 places bendings of mentioning of feasible projection.The electric arc control bus 12 that has projection 31 can be made by parts.These parts are the sheet metal bending part of steel preferably.Steel is owing to its magnetic, robustness and low cost are preferably used.Electric arc controls bus 12 and the first limit leg, 32 housings are supported regularly and maintenance, and this can adopt various mode to realize, for example by the clamping between bridgeware realizes in the housing inboard.It is removable that supporting leg 4 must keep, as in the above in conjunction with as described in thermo bimetal's adjusting.The fixing position of the first limit leg 32 is very important for the release property of heat because adjusted once after thermo bimetal 2 also be maintained fixed thus with respect to the position of latching device 8.
Fig. 1 is to decompose
Detail drawing illustrate projection 31 and with the situation that is connected of input terminal 9.Can see that electric arc control bus 12, the first limit leg 32 and the second limit leg 4 are designed to the sheet metal bending part of steel integratedly.Bending position on form support end 5, the steel band sheet is slotted.Produce the part strap 41,42 of two extends parallel thus.One of these part straps are bent downwardly as support arm 41.The part strap 42 that is positioned at its next door is also referred to as contact arm 42, and stretches afterwards bending once more vertically downward through short-range, and flatly towards input terminal 9.Therefore it form first conductor segment 14, and this conductor segment is welded on and the bus-bar of input terminal 9, the connecting portion 33 of terminal board 29.Input terminal 9 for example can be known two-stroke-cylinder terminal.Terminal board 29 is a bus-bar at this, presses against on the described bus-bar under the bonding conductor of access or the situation of tightening clamped at terminal, and produces electricity and mechanical being connected thus between bonding conductor and terminal board.Comprise electric arc control bus 12, projection 31, thermo bimetal's strap 2 (not shown in figure 1)s and can make prefabricated construction unit, and adopt simple mode to be encased in the installation switchgear when mounted by the construction unit of terminal board 29 welding input terminal 9 thereon.According to the utility model, in construction unit, do not use flexible twisted wire, but use fixing bus-bar or conductor strap fully, they are welded to each other, can certainly spiral connect or adopt other known mode power to cooperate and/or material fit interconnect.Use fixed part and abandon using flexible twisted wire can be implemented in being easy to control assembly when installing.
The free end 6 of support arm 41 is stair-stepping L shaped, thereby the stationary plane 61 at place has certain spacing at a distance of support arm 41 during the stiff end 3 of sweating heat bimetallic strap.Therefore thermo bimetal's strap 2 can clamp the position bending around it under the situation that does not contact support arm 41.Above the clamping position, the outstanding flag shape part 43 of side direction is installed on support arm.This flag shape part is formed for the bearing of adjustment screw 13.Adjustment screw 13 stretches near the plane thermo bimetal's strap 2 thus, and can not have influence on this thermo bimetal's strap.Can realize saving very much ground, space in this way is arranged on component heat circuit breaker 34 in the housing of installation switchgear 1.
