Description
Technical field
The utility model relates to power supply system testing tool, is specifically related to a kind of integrated capacitor group test device for insulation resistance.
Background technology
The megger test of integrated capacitor group is an important process in power supply system upkeep operation.At present, the on-the-spot test of integrated capacitor group insulation resistance, adopt traditional wiring method of testing, because integrated capacitor group test wiring position is higher, need to change wiring with ladder or stool ascend operation and complete test and the electric discharge to every phase insulation resistance, therefore workload is larger, and test needs the time longer, the measurement phase that possibility false touch is not simultaneously discharged, causes personal injury.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of integrated capacitor group test device for insulation resistance is provided, and uses this device can effectively reduce test job amount, improves test job efficiency, guarantees test job safety.
The technical scheme that realizes above-mentioned purpose is: a kind of integrated capacitor group test device for insulation resistance, it comprises an insulation lever, the front end coaxial cable of this insulation lever connects a discharge metal head, this discharge metal head connects a ground wire, the other end of this ground wire connects an earthing clamp, three axial through holes are set on described insulation lever and discharge metal head, in each through hole, penetrate respectively an insulating sleeve, in each insulating sleeve, penetrate respectively a p-wire, the conductor wire core of each p-wire is connected with the test ferrule that coaxial cable is respectively connected to described each insulating sleeve front end, the conductor wire core other end of each p-wire connects respectively a pair of measurement wire clamp.
Described insulation lever and discharge metal head are cylindrical.
The utility model is compared with traditional integrated capacitor group megger test method, and tool has the following advantages:
1, two test clamps that test wiring is drawn with a p-wire have replaced traditional wire and have been wound around short circuit, make easy-to-connect quick;
2, while test, only need primary connection just can, by the operation of device being completed to the megger test of three-phase, avoid repeatedly ascending a height wiring, reduced test job amount, improved test job efficiency;
3, while test, operating personnel and insulating megger, all on ground, have been avoided the possibility of people and thing falling from high altitude, and commutation test operation in test process, all hold corresponding insulating element, avoided the personal injury occurring because of error shock container group current-carrying part.
Accompanying drawing explanation
Fig. 1 is this integrated capacitor group test device for insulation resistance structural representation.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described:
As accompanying drawing, this integrated capacitor group test device for insulation resistance, comprises an insulation lever 1 and the discharge metal head 2 that is connected to this insulation lever 1 front end, and this insulation lever 1 and discharge metal head 2 are applicable to being designed to cylindrical, connect by bonding coaxial cable.Discharge metal head 2 connects a ground wire 3 by binding post, and the other end of this ground wire 3 connects an earthing clamp 4.Three axial manholes distribute on the insulation lever 1 being combined into one and discharge metal head 2, in each through hole, penetrate respectively an insulating sleeve 5, each insulating sleeve 5 coordinates with three axial circular via clearance that arrange on insulation lever 1 and discharge metal head 2, and insulating sleeve 5 can be slided in described manhole.Each insulating sleeve 5 is interior penetrates respectively a p-wire 6, and this p-wire 6 is made up of insulation sheath and two strands of conductor wire cores.The conductor wire core of each p-wire 6 is electrically connected with the test ferrule 7 that coaxial cable is respectively connected to described each insulating sleeve 5 front ends, the test ferrule 7 of accompanying drawing embodiment is right cylinder, this cylindrical diameter is less than the manhole on discharge metal head 2, makes to test ferrule 7 and can enter in the manhole on discharge metal head 2.Test ferrule 7 and can adopt bonding or threaded engagement connection being connected of insulating sleeve 5.The conductor wire core other end of each p-wire 6 connects respectively a pair of measurement wire clamp 8.
This device is as follows for the survey formula step of integrated capacitor group megger test: 1, by earthing clamp good earth; 2, three test ferrule are all moved in the through hole of discharge metal head; 3, six measurement wire clamps of three measuring units are distinguished to corresponding clips on capacitor three-phase electrode, realize interpolar short circuit; 4, hold the insulating sleeve of measuring unit, the test ferrule of this measuring unit is pushed into test position, and measures insulation resistance, other two-phase test ferrule is still retained in the through hole of discharge metal head; 5,, after a phase Insulation test, hold ground connection electric discharge in the through hole that insulating sleeve is withdrawn into the test ferrule of this phase measuring unit on discharge metal head; 6, after fully discharging, repeating step 4,5, completes the test of all the other two-phase insulation resistances.
