Description

Bimetal leaf mechanism and thermal relay
Technical field
The utility model relates to a kind of thermal relay, relates in particular to a kind of bimetal leaf mechanism of thermal relay.
Background technology
In the electric power system, thermal relay is a kind of relay commonly used.The purposes of thermal relay is very extensive, therefore, replaces the thermal relay quantity of getting off because breaking down also very huge.If exist the thermal relay of fault to reclaim, disassemble, assemble to these, can produce fairly obvious economic benefit.Through the fault of a large amount of thermal relays is analyzed, the damage of finding bimetal leaf mechanism is more, and find that the common ground that a lot of thermal relays damage is: single-phase or two-phase is wrapped in the wire fusing on the bimetal leaf, but auxiliary node is intact with residue sheet metal mutually on each thermal relay, be which intact parts can also be used on other thermal relays, if because a thermal relay that has fault is abandoned in the damage of bimetal leaf mechanism, real is unfortunate, therefore need a kind of bimetal leaf mechanism of design in order in polyphase circuit, during the bimetal leaf mechanism failure of a certain phase, can simply replace intact bimetal leaf mechanism; Perhaps damage at other position of thermal relay and bimetal leaf mechanism when not being damaged, intact bimetal leaf mechanism can be removed as parts for subsequent use.
Summary of the invention
The thermal relay that the purpose of this utility model is to provide a kind of bimetal leaf mechanism and has this bimetal leaf mechanism causes the abandoned problem of thermal relay with what the solution prior art existed because bimetal leaf damages.
To achieve these goals, the bimetal leaf mechanism that the utility model provides is characterised in that, described bimetal leaf mechanism is made of bimetal leaf section and bearing, described bimetal leaf section comprises heating resistance wire, insulation integument and bimetal leaf, described insulation integument be coated on described bimetal leaf around, described heating resistance wire is wound in the outside of described insulation integument, described bimetal leaf section is fixed on the described bearing, described bearing is provided with screw, by cooperating of screw and described screw described bimetal leaf mechanism being fixed on the electromechanical equipment.
According to a kind of preferred implementation of above-mentioned bimetal leaf mechanism, wherein, described bearing is L-shaped.
According to a kind of preferred implementation of above-mentioned bimetal leaf mechanism, wherein, the end of described bimetal leaf section is fixed on the described bearing.
The thermal relay that the utility model provides comprises: housing; With above-mentioned arbitrary described bimetal leaf mechanism, utilize screw that screw is provided with by described bearing that described bimetal leaf mechanism is fixed on the described housing.
According to a kind of preferred implementation of above-mentioned thermal relay, wherein, described thermal relay has a plurality of described bimetal leaf mechanisms and a plurality of described bearing, and each described bimetal leaf mechanism is individually fixed on the described bearing.
Because bearing of the present utility model is convenient to dismounting, therefore after a bimetal leaf mechanism damages, can change easily the bimetal leaf mechanism of other thermal relays, the utility model can save production cost like this, solve on-the-spot practical problem, and that the utility model also has advantages of is simple and practical, easy operating, raising work on the spot efficient.
Description of drawings
Fig. 1 is the structural representation of the bimetal leaf mechanism of the utility model preferred embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Thermal relay based on this preferred embodiment comprises housing (claim again bimetal leaf mechanism to fix and use pedestal, be not shown) as shown in Figure 1 the bimetal leaf mechanism identical with a plurality of structures.Fig. 1 schematically shows the structure of the bimetal leaf mechanism of the utility model preferred embodiment, as shown in the figure, wherein said bimetal leaf mechanism comprises a bimetal leaf section and a bearing 4, described bimetal leaf section comprises heating resistance wire 3, insulation integument 2 and bimetal leaf 1, the insulation integument 2 be coated on bimetal leaf 1 around, heating resistance wire 3 is wound in insulation integument 2 outsides, and an end of bimetal leaf section is fixed in described bearing 4.
Fig. 1 only illustrates a bearing 4 of this preferred embodiment, but the thermal relay that is based on this preferred embodiment can comprise the bimetal leaf mechanism that a plurality of structures are identical, like this so that the parts between this preferred embodiment have interchangeability, (an end and bearing 4 such as bimetal leaf section are connected and fixed) on the bearing 4 is fixed in a bimetal leaf section, and bearing 4 is provided with screw 41 by screw bearing 4 is fixed on the housing of thermal relay.
In this preferred embodiment, bearing 4 is L-shaped, and certainly, the utility model is not as limit.
In this preferred embodiment, the bimetal leaf mechanism of different thermal relays is identical with seat structure, function is identical, bimetal leaf mechanism and bearing thereof can be general, bearing is easy to dismounting, therefore, and when the bimetal leaf mechanism of a preferred embodiment shown in Figure 1 breaks down, the dismantle identical bimetal leaf mechanism of preferred embodiment shown in Figure 1 of another damage changes, and the thermal relay that damages has so just been fixed.Through test, the parameters of keeping in repair complete thermal relay meets the demands.
To sum up, the utility model can meet the standardized management requirement by device; In practical work process, can save production cost, turn waste into wealth, farthest realize the Work tool recycling; Can increase work efficiency economic benefit.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
