Description
Technical field
The present invention relates to Low Voltage Electrical Apparatus, more particularly to a kind of auxiliary switchgear of permutator.
Background technology
Automatic transfer switching electric appliance needs auxiliary switchgear to reflect the opening and closing state of main contact, and main contact is double
Divide, main power source is closed, stand-by power source closes three kinds of states or main power source is closed, stand-by power source is closed under two states, auxiliary switch needs are given
Corresponding signal, for controller using realizing being automatically brought into operation permutator；Separately wiring can connect display lamp simultaneously, use
In the opening and closing state for showing permutator.
There is three below in general auxiliary switchgear：1) Contact Breaking/Making Operations of automatic change-over can not truly be reflected
Lock state.If auxiliary switchgear is triggered by operating mechanism, rather than by contact directly triggering, then once behaviour
Making mechanism can not be synchronous with contact, and such as contact melting welding or mechanism are damaged, then may result in auxiliary switch status and contact
State it is inconsistent, cause permutator cannot normal work, or even the personal safety that operator can be threatened.2) auxiliary is opened
It is unreliable to close.Microswitch in auxiliary switch is not secured on same part with the part of triggering microswitch, they
Between dimension chain it is long, so due to the accumulation of error, cause to trigger relative between part and the trigger head of microswitch
There is larger error in distance, if microswitch trigger head can be caused too to be extruded apart from too small, may normal bullet
Go out or even cause microswitch to damage, cause microswitch trigger head be triggered as normal if distance crosses conference, cause auxiliary
Help on off state mistake.3) permutator to different frame sizes, auxiliary switch can not be general.The switch of every kind of frame size
The different auxiliary switch of assembling, increased cost.
The content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of auxiliary switchgear of permutator, can direct reaction
The division situation of moving contact, reliability are high, simple structure, it is easy to accomplish.
