Description
Technical field
The utility model belongs to the high voltage electric equipment technical field, is specifically related to a kind of switching mechanism.
Background technology
In electric power networks, there are many users to require very high to power supply reliability, for example colliery and oil plant, in a single day power outage takes place in these units, will bring great economic loss even cause casualties to unit, so in the electric power system of these units, all need to have main power source and stand-by power supply, when power outage appears in main power source, stand-by power supply must drop into immediately and restore electricity, in order to achieve this end, need between main power source and stand-by power supply, automatically switch by the duplicate supply switching mechanism.
Traditional duplicate supply switching mechanism is to adopt two high-tension switch cabinets to add the extremely complicated electric interlocking installation of a cover, is strictly on guard against two loop paired runnings.This duplicate supply device has following three big defectives: (1) locking is unreliable: at present, the electrical interlocks reliability is too low, forbids to use, and mechanical interlocking device country does not have unified design specification standard again, can only be designed voluntarily, be transformed by various places.(2) complicated operation, and easy jam cause electric power accident; (3) investment is big, need purchase two switch cubicles, designs locking device then, is retrofitted on the switch cubicle again.
Domestic duplicate supply switching mechanism generally is to adopt two primary cut-outs at present, the end of incoming cables of every primary cut-out is connect one road power supply, leading-out terminal with two primary cut-outs connects together then, and realizes main power source and stand-by power supply are switched rapidly by electric interlocking installation.The shortcoming of this duplicate supply switching mechanism is that functional reliability is relatively poor, and may cause serious accident; For example be when regular maintenance is carried out in the power failure of main power source power supply circuits, coil burnout in the primary cut-out that main power source may be connected falls, but the circuit in this primary cut-out still keeps channel status, at this moment, another primary cut-out in this kind duplicate supply switching mechanism can connect stand-by power supply at once and continue power supply, the main power source power supply circuits that will cause script should cut off the power supply like this are also charged, are easy to cause the maintenance personal who overhauls main power circuit that electric shock accidents takes place.In addition, owing to need purchase two primary cut-outs, invest also bigger.
At present, the switching mechanism that is used for common primary cut-out comprises isolation knife, and described isolation knife is connected with rotating shaft on being fixed on housing by insulated tension pole; Its switching operation generally is the handle by the hand rotation rotating shaft, thereby drive isolation knife and tool rest switch on and off.This pure manual operations can not have been satisfied the requirement of highly intelligent dual-power automatic switching device needs automatic switchover main power source and stand-by power supply.
