Description
Technical field
The utility model relates to a kind of additional alarm contact, and particularly a kind of low-voltage circuit breaker additional alarm contact belongs to low-voltage electrical apparatus attachment technique field.
Background technology
Low-voltage circuit breaker is suitable for exchanging 50Hz, insulation voltage is in the following distribution network of 800V, rated operational voltage 690V; be used to distribute electric energy and protection circuit, power supply and power consumption equipment; circuit breaker has overload, short circuit, under voltage protection function, and energy protection circuit and power-supply device are not damaged.The low-voltage circuit breaker contents mainly includes shunt release, under-voltage release, auxiliary, Alarm contactor.Auxiliary, Alarm contactor provides position signalling and alarm signal when combined floodgate, separating brake, the fault dropout position for circuit breaker, wherein auxiliary contact is mainly used in provides circuit breaker to be in the index signal of on off operating mode, at circuit breaker during from "on" position to gate-dividing state, the push rod that rotation by breaker rotating axis promotes on the auxiliary contact is done motion vertically upward, promote auxiliary sensitive switch with this, different signals is exported in conversion by auxiliary sensitive switch upper contact, reaches the purpose of indication circuit breaker on off operating mode; Alarm contactor is mainly used in provides circuit breaker to hinder the index signal of trip status for some reason, when circuit breaker tripping, be fixed on revolving meber on the tripping gyroaxis and leave the fork of Alarm contactor, different signals is exported in conversion by warning sensitive switch upper contact, reaches the purpose that the indication circuit breaker is in trip status.
In the prior art, auxiliary, the Alarm contactor (being called for short auxilliary newspaper contact) of circuit breaker is split production normally, when circuit breaker needs miscellaneous function, auxiliary contact can be installed separately; When circuit breaker needs warning function, Alarm contactor can be installed separately; And during, warning function auxiliary when needs, can with assist, Alarm contactor is installed in the circuit breaker simultaneously.The defective that this split-type structural exists is: at first, complex structure, parts are many; Secondly, load and unload loaded down with trivial details; Again, because auxiliary, the warning sensitive switch that are located in auxiliary, the Alarm contactor respectively have only one, its function is comparatively single.Therefore, in order to satisfy user's needs, realize the additional alarm multifunction, the technical staff continually develops research, for example: a pair of auxiliary sensitive switch is set on the contact base, and adopts stacked mode up and down, dispose two pieces of auxiliary push-rods simultaneously, to realize many miscellaneous functions.One of problem that this stacked mode exists, because the position of a pair of auxiliary sensitive switch by the sampling point of two pieces of push rods on breaker rotating axis is different, cause the stressed position of corresponding contact on a pair of auxiliary sensitive switch inconsistent, can not realize synchronous conversion; Two, complex structure; Three, reliable in action is poor.Again for example: on the contact base, be provided with many to auxiliary sensitive switch, and adopt stacked mode up and down, only dispose simultaneously one piece of auxiliary push-rod, to realize many miscellaneous functions, this frame mode, although each is identical to assisting sensitive switch by the position of the sampling point of one piece of push rod on breaker rotating axis, but because each is inconsistent to the stressed position of corresponding contact on push rod on the auxiliary sensitive switch, cause each and can not realize synchronous conversion equally, and reliable in action is relatively poor assisting between sensitive switch.
In sum, auxiliary, Alarm contactor of the prior art can not satisfy the desired multifunctional modular of modern Electrical Appliances Designing.
Summary of the invention
