Description

Handle apparatus, breaker and switch cubicle

Technical field

The utility model is related to switch cubicle technical field, more particularly to handle apparatus, breaker and switch cubicle.

Background technology

In technical field of electricity, breaker can by the separating brake of dynamic/static contact, close a floodgate and cut off, connect electric current, and oneself Dynamic disengagement failure circuit.

In some applications it is desirable to using circuit breaker handle, such as by being referred to as the transmission device that hand is grasped, operation open circuit The operating mechanism of device, to realize the separating brake of breaker, close a floodgate.

The operational torque of the breaker of high current is larger, in order to improve user's operation comfort, typically can be using lengthening hand The mode of handle length is come the operating physical force needed for reducing.But, used if handle will be placed in switch cubicle, decreased food by The limitation of floor space.

In the case where decreased food is limited, in order to ensure the comfortableness of user's operation, some products employ dual-handle Design, i.e. handle both sides are all lengthened.But when user operates this handle every time, it is necessary to while using both hands, still causing not Just.

Product also uses the design of one extension handle of additional.Extend handle as extra and install accessory additional, It will not be attached on handle, but in user's operated products, extension handle is connected on handle under normal circumstances.So need Want user frequently to install/pull down extension handle, still operation comfort is impacted, and extension handle is used as independent accessory It is easily lost.

Handle is located at production by product also using the space of product in order to extend the length of handle with the binding site of body One side of product.During normal mounting, handle can be placed in switch cubicle not over the appearance and size of whole product.But, it is this Mounting means lacks flexibility.For example, much requiring that product is rotated by 90 ° in the environment of installation, this design can cause handle Beyond switch cubicle size, it is impossible to be placed in switch cubicle.

Therefore, there is opponent's handle in industry to be improved in order to user security simple operations and without prejudice to switch cubicle folding Demand.
