Three i.e. load side of line that the static contact of device main contact KM-1 connects are connected on three display lamps respectively, and between three display lamps
Be combined through series connection switch two groups of auxiliary contact SA5,6 and SA9 of SA, 10, from the display lamp other end return to transformator constitute constitute 24V
Loop；Vacuum contactor combined floodgate circuit is Circuit Fault on Secondary Transformer 36V circuit, one end connect stop button TA, stop button TA with
Start button QA connects, and start button QA is connected with vacuum contactor KM coil, and is drawn by vacuum contactor coil and be connected to instrument
The i.e. winding wiring of panel presss from both sides, and the self-insurance point KM-2 of vacuum contactor is attempted by start button QA two ends, is drawn by self-insurance line simultaneously
It is connected in board i.e. self-insurance ramp, then returns to the 36V other end from contactor coil and constitute 36V loop.
Normally opened some SA3 of auxiliary from cubicle switch SA, 4 piece L lines of extraction, from two groups of auxiliary contact of cubicle switch SA
SA5,6 and SA9,10 piece G lines of extraction.
The exchange 12V power supply that transformator TC secondary side exports is exported direct current 12 V power supply after bridge rectifier, one
End connects a scram button TA2, and then a three-phase display lamp in parallel, constitutes silicon controlled thyristor detecting circuit.
Good effect of the present utility model is: simple to operate, easily debugs, and a people is the most operable；Carrying out vacuum tube regulation
Time, only circuit need to be connected on request and switch on power, because phase vacuum tube has the display lamp of correspondence, so operator exist
When carrying out a phase operation, judged the make and break situation of this phase vacuum tube by viewing lamp, moreover it is possible to by observing another biphase finger
Show the change of lamp, it is judged that the make and break of vacuum tube, to reach quickly to regulate；When shaking survey, only the line of megameter need to be connected to
Just the insulation of vacuum tube can be shaken survey on terminal, it is not necessary to just can judge the insulating properties of vacuum tube by carrying out mutually shaking surveying
Energy；This device obtains good result through test of many times and actual application.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model electrical schematic diagram.
Detailed description of the invention
As shown in Figure 1, it includes transformator TC, vacuum contactor vacuum tube testing circuit 1, silicon controlled thyristor detecting circuit 2
With vacuum contactor combined floodgate circuit 3, Circuit Fault on Secondary Transformer 36V, one end connects stop button TA, stop button TA and start button
QA connects, and start button QA is connected with vacuum contactor KM coil, and is drawn by vacuum contactor coil and be connected to board i.e. line
Circle ramp, is attempted by start button QA two ends by the self-insurance point KM-2 of vacuum contactor, is drawn by self-insurance line simultaneously and be connected to instrument
It it is self-insurance ramp on panel.Then return to the 36V other end from contactor coil and constitute 36V loop；Circuit Fault on Secondary Transformer 24V,
One end connect normally opened some SA3 of auxiliary of cubicle switch SA, 4, when cubicle switch SA is in zero-bit, SA3,4 be in disconnection shape all the time
State；Clip to board i.e. mains side and a L line from SA3,4 three line wiring of extraction, three electrical wire clips are added in very respectively
The moving contact end of empty main noddle on contactor KM-1, three ramps then vacuum contactor main contact KM-1 static contact connected
I.e. load side is connected on three display lamps respectively, and two groups of auxiliary contact SA5 of the switch SA that is combined through series connection between three display lamps,
6 and SA9,10 and draw a G line, return to transformator from the display lamp other end and constitute 24V loop.Test illumination integrated protection for convenience
The controllable silicon of switch, exports direct current 12 V electricity after bridge rectifier by the exchange 12V power supply that transformator TC secondary side exports
Source, one end connects a scram button TA2, and then a three-phase display lamp in parallel, constitutes silicon controlled thyristor detecting circuit.
Operation principle of the present utility model:
Close air-break, and transformator TC primary side input 220V power supply, power supply indicator is bright simultaneously, and secondary side exports
36V、24V、12V.First power clip is connected on respectively the coil power of tested vacuum contactor, self-insurance point and vacuum contactor
The both sides of main contact.Before reparation, the cubicle switch SA in board is rotated to " 1 " file location, makes contact SA3,4 Guan Bis,
This state is reparation state.When pressing start button QA, vacuum contactor KM adhesive, main contact flows into 24V power supply simultaneously, connects
The three-phase display lamp entering main contact is bright.If vacuum contactor would indicate that when not having adhesive lamp bright explanation vacuum contactor master touches
Head adhesion, if vacuum contactor adhesive rear indicator light does not works or not all light, illustrates that main contact does not has adhesive or has disconnected phase situation.
Just can be by regulating stroke and the synchronization degree of vacuum tube manually when adhesion or phase shortage occur；Press stop button TA, very
Empty catalyst adhesive debugging process terminates.
L, G both threads folder drawn shakes survey in order to vacuum contactor is carried out insulation, solves by the trouble shaking survey mutually.Will
In board, cubicle switch SA rotation (has also cut off vacuum contactor debugging measure loop, in case shaking survey to " 2 " shelves simultaneously
Display lamp is punctured during insulation), the auxiliary contact SA5 of cubicle switch SA, 6, SA9,10 Guan Bis, vacuum tube one end is carried out short circuit.
At this moment 5000V megameter indicator is accommodated respectively on two terminals of L, G, it is possible to same to the three-phase vacuum tube of vacuum contactor
Survey is shaken in Shi Jinhang insulation.
For convenience of the controllable silicon of test illumination integrated protection switch, the exchange 12V power supply exported by transformator TC secondary side is through bridge
Direct current 12 V power supply is exported after formula rectification circuit.During detection, DC12 V power supply is connected on silicon controlled power end, respectively by power supply
The three-phase terminal of side and load side is connected on silicon controlled power supply and load side, and outward winding after having connected scram button TA2, if three-phase
Display lamp bright explanation controlled silicon conducting, on the contrary controllable silicon damages.
