Abstract
The utility model discloses a hydraulic electromagnetic circuit breaker, which comprises an insulating base (8) and a total support (7) arranged on the insulating base (8). The total support (7) is connected with a coil rack (10) and a release device, and the coil rack (10) is provided with a hydraulic cylinder (9) with a pole shoe (11) at the upper end. The hydraulic electromagnetic circuit breaker is characterized in that the release device comprises a handle (1) and an armature (12), the handle (1) is arranged on the insulating base (8) via a pin (2) and is successively hinged with a tripping pin (3), a lock catch ( 5) and a movable contact (6), and one end of the armature (12) is close to one side of the lock catch (5) while the other end of the armature (12) is disposed above the pole shoe (11). The hydraulic electromagnetic circuit breaker not only can guarantee normal release, but also is simple in structure and convenient in installation, and reduces production cost.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of hydraulic electromagnetic circuit breaker.
Background technology
Existing circuit breaker generally has Thermomagnetic type circuit breaker and hydraulic pressure magnetoelectricity circuit breaker, the Thermomagnetic type circuit breaker is provided with a bimetal leaf of connecting with circuit, the heat that is generated by electric current during overload makes the bimetallic distortion, thereby make circuit breaker tripping, when in a cold environment, working, need bigger electric current to thread off, thereby jeopardize safety, and when in a thermal environment, working, can under less current, thread off.And cause the unnecessary disconnection of circuit; On the insulating base of hydraulic pressure magnetoelectricity circuit breaker a support is set all, fixedly is wound with the bobbin and the tripping mechanism of coil on the support, tripping mechanism comprises that an end is fixed on the armature of coil top, and the armature other end is near a side of snap close.When coil electricity, the pole shoe of coil is inhaled moving armature, make the snap close of stirring of armature, the effect that latches in spring drives the moving contact tripping operation down, moving contact is disconnected with fixed contact be connected, reach the purpose of cutting off circuit, the snap close of tripping mechanism need connect spring threads off, and the structure more complicated can make that installation is comparatively loaded down with trivial details, and the processing technology of part has relatively high expectations, and improved production cost.
The utility model content
The purpose of this utility model is, a kind of hydraulic electromagnetic circuit breaker is provided.The utility model can not only guarantee normal dropout, and simple in structure, and is easy for installation, reduced production cost.
The technical solution of the utility model: a kind of hydraulic electromagnetic circuit breaker, comprise insulating base and the total support that is arranged on the insulating base, on total support, be connected with the bobbin and the trip gear that can be wound with coil, bobbin is provided with the hydraulic cylinder of upper end band pole shoe, it is characterized in that: described trip gear comprises that via pins is arranged on handle and the armature on the insulating base, handle is hinged with tripping, snap close and moving contact successively, one end of armature is near a side of snap close, and the other end is arranged on the top of pole shoe.
In the aforesaid hydraulic electromagnetic circuit breaker, the central part of described snap close radially is provided with a through hole, and the through hole is provided with a roller bearing.
In the aforesaid hydraulic electromagnetic circuit breaker, described hydraulic cylinder lower end is provided with lubricating cup.
Compared with prior art, the utility model adopts handle, tripping, snap close and the moving contact composition trip gear that is articulated and connected successively, can be because of normal dropout of cold and hot situation influence of operational environment, and implement simple in structure, feasible installation is comparatively convenient, also have the manufacturing technique requirent of each parts lower, handling ease can reduce production costs; Central part at snap close directly upwards is provided with a roller bearing, can make in the dropout process more along sliding.In addition, simple and effective trip gear can also guarantee the dropout rate, guarantees the safety of producing.The utlity model has easy to use and characteristic of simple structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-handle, 2-pin, 3-tripping, 4-roller bearing, 5-snap close, 6-moving contact, the total support of 7-, 8-insulating base, 9-hydraulic cylinder, 10-bobbin, 11-pole shoe, 12 armature, 13-lubricating cup.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of hydraulic electromagnetic circuit breaker, constitute as shown in Figure 1, comprise insulating base 8 and the total support 7 that is arranged on the insulating base 8, on total support 7, be connected with the bobbin 10 and the trip gear that can be wound with coil, bobbin 10 is provided with the hydraulic cylinder 9 of upper end band pole shoe 11, characteristics are: described trip gear comprises that via pins 2 is arranged on handle 1 and the armature 12 on the insulating base 8, handle 1 is hinged with tripping 3 successively, snap close 5 and moving contact 6, one end of armature 12 is near a side of snap close 5, the other end is arranged on the top of pole shoe 11, and described hydraulic cylinder 9 lower ends are provided with lubricating cup 13.
Reasonablely be, radially be provided with a through hole at the central part of described snap close 5, the through hole is provided with a roller bearing 4, can make snap close 5 activities more along sliding.
Use principle of the present utility model is: with handle 1, tripping 3, snap close 5 and the moving contact 6 composition tripping mechanism that is articulated and connected successively; when load current overcurrent or short circuit current occur through coil; coil produces electromagnetic force; movable core in the hydraulic cylinder 9 attracts armature to move; the other end of armature 12 impacts snap close aside because of lever principle, thereby snap close 5 rotations are threaded off tripping mechanism; thereby moving contact 6 is separated with fixed contact, reach the purpose of protection.
