Specific embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
The present invention provides a kind of power supply fast switching device maintenance analog switch, can simulate work electricity by analog switch
Source and the position signalling of Backup Power Switch, carry out inspection functionally to power supply fast switching device.In checkout procedure, two are used
Platform two-position relay simulates the switch of working power and stand-by power supply, need not carry out actual conjunction to working power and stand-by power supply
Lock and trip operation, do not affect normal production, it is ensured that the production process of steady safety.
As shown in drawings, the present invention is connected with power supply fast switching device to be measured during use for overhauling power supply fast switching device
Connect, the present invention includes No. 1 two-position relay, No. 2 two-position relay, No. 1 two-position relay cuts dress soon with power supply
The working power put is closed a floodgate, trip switch connection, and No. 2 two-position relay are closed a floodgate, jumped with the stand-by power supply of power supply fast switching device
Lock switch connection.No. 1 two-position relay normally-closed contact K1:The switching signal of 1 simulation working power switch, No. 1 dibit
Put relay normally open contact K1:The trip signal of 2 simulation working powers, No. 2 two-position relay normally-closed contact K2:1 simulation is standby
With the switching signal of on and off switch, No. 2 two-position relay normally opened contact K2:The trip signal of 2 simulation Backup Power Switch.Institute
State No. 1 two-position relay normally-closed contact K1:1 is in parallel with the working power closing switch K1 of power supply fast switching device, No. 1 two-position
Relay normally open contact K1:2 is in parallel with working power trip switch K2, No. 2 two-position relay normally-closed contact K2:1 with it is standby
Power supply closing switch K3 is in parallel, No. 2 two-position relay normally opened contact K2:2 is in parallel with stand-by power supply trip switch K4.Work as work
When power supply closing switch K1 is closed, working power trip switch K2 is opened, No. 1 two-position relay normally-closed contact K1:1 closure, 1
Number two-position relay normally opened contact K1:2 open, simulation working power switch switching signal, now, Backup Power Switch simulation
Trip signal.When working power closing switch K1 is opened, and working power trip switch K2 is closed, according to selected switching mould
Formula, determines that power supply fast switching device carries out corresponding operation to stand-by power supply closing switch K3 and stand-by power supply trip switch K4.
When overhauling to power supply fast switching device, the present invention is connected with power supply fast switching device to be measured.
The present invention can be used for maintenance most of power supply fast switching devices on the market, not limited by model.By this device and electricity
After the fast switching device connection of source, carrying out switching examination when various running statuses and switching mode can be simulated when fast switching device is tested
Test (such as：Switching, the switching of bus low-voltage during switching, switching in parallel, protection startup switching, the switch jump of connecting etc.), while
Can be with the fault alarm of fast switching device during analog switch position signalling mistake and blocking function.
Maintenance series connection switching mode：Working power of closing first trip switch K2, if power supply fast switching device can quickly certainly
Stand-by power supply closing switch K3 in dynamic circuit connector, then the series connection switching mode fault-free of the power supply fast switching device, normally can use.
Maintenance switching mode in parallel：Close stand-by power supply closing switch K3 first, if power supply fast switching device quickly can be closed
Upper working power trip switch K2, then the switching mode fault-free in parallel of the power supply fast switching device, normally can use.The switching side
Formula requires that working power and stand-by power supply are in parallel relationship, i.e., No. 1 two-position relay and No. 2 two-position relay parallel connections.
Maintenance protection starts switching：Electromotor, transformator break down or shut down, and after implementing protection act, start electricity
Source fast switching device is operated power supply and stand-by power supply is carried out while the switching that switches or connect.
Switch jump switching：When working power switch breaks down tripping operation, if power supply fast switching device can be by standby electricity
Source closing switch K3 automatic closings, then the switch jump switching mode fault-free of the power supply fast switching device, normally can use.
Bus low-voltage switches：When system jam causes service power busbar voltage to be reduced to threat electrical equipment fortune
During row, if power supply fast switching device switches or connect switching while being operated power supply and stand-by power supply, ensured with this
The normal operation of station-service subsidiary engine, then the power supply fast switching device bus low-voltage switching mode fault-free, normally can use.
Under the switching mode selected, if power supply fast switching device is no quickly and accurately switched and standby in working power
Switch between on and off switch, you can think that the power supply fast switching device has failure.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, some improvements and modifications can also be made, these improvements and modifications
Should be regarded as protection scope of the present invention.
