Abstract
The utility model discloses a J-1 type special rod for 10kV switch cabinet arrester test, comprising a hollow insulating rod, a testing core wire and a testing shielding wire. The hollow insulating rod is equipped with a metal hook in the top, a first shielding ring in the upper, and a first circular hole in the middle; one end of the testing core wire is connected with the bottom of the metal hook, and the other end of the testing core wire is led out from the hollow insulating rod via the first circular hole; a second shielding circular ring and a second circular hole are arranged below the first circular hole; and one end of the testing shielding wire is connected with the first shielding ring, and the other end of the testing shielding wire is led out from the second shielding circular ring via the second circular hole. During use of the J-1 type special rod, a contact in an instrument end of the testing core wire is connected with an instrument, the other end of the testing shielding wire is connected with a housing of a high-voltage microammeter, the metal hook is connected with the lightning arrester, and the instrument is powered on to carry out insulation test. The J-1 type special rod for 10kV switch cabinet arrester test is highly accurate, avoids misjudgment of equipment, and eliminates hidden safety troubles.
Description
Technical field:
The utility model relates to a kind of high-voltage test of electrical equipment equipment, particularly relates to a kind of J-1 type 10kV switch cabinet lightning arrester test special pole.
Background technology:
Finite volume due to the 10KV switch cubicle, consider the safe distance of the normal operation of equipment, the installation site of lightning arrester is generally all near the cabinet inboard, while making like this lightning arrester be tested, dismounting is very difficult, and experimental test line and cable can not keep enough safe distances, and old test special pole has following shortcoming: 1. measure inaccurately, equipment is produced to erroneous judgement disconnected, have potential safety hazard; 2. there is tip easily to cause electric discharge phenomena, cable insulation is produced to the undesirable elements such as build-up effect and External Insulation destruction.
The utility model content:
Technical problem to be solved in the utility model is: a kind of J-1 type 10kV switch cabinet lightning arrester test special pole that lightning arrester just can accurately be measured test that do not need to remove is provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of J-1 type 10kV switch cabinet lightning arrester test special pole, comprise hollow insulating bar, test heart yearn and test shielding line, described hollow insulating bar top is provided with metal hook, top is provided with the first shading ring, middle part arranges the first circular hole, described test heart yearn one end is connected with the metal hook bottom, and the other end extracts from the hollow insulating bar by the first circular hole; Described the first circular hole lower end is provided with secondary shielding annulus and the second circular hole, and described test shielding line one end is connected with the first shading ring, and the other end extracts from the second circular hole by the secondary shielding annulus.
Described the first circular hole and the second circular hole are at a distance of 5～8 centimeters.
Described secondary shielding annulus is positioned at hollow insulating bar inside.
The beneficial effect that the utility model can reach is:
In use, the instrument end connector that at first will test heart yearn connects instrument to the utility model, then the other end that will test shielding line receives on the shell of high voltage microammeter, finally metal hook is connected with lightning arrester, opens instrument power source and carries out Insulation Test.The utility model accuracy of measurement is higher, has avoided the false judgment to equipment, has eliminated potential safety hazard.
The utility model is by arranging shading ring on hollow insulating bar top and middle part, the test shielding line extracts on the shell of directly receiving high voltage microammeter from the second circular hole by the first shading ring and secondary shielding annulus, has reduced the build-up effect to cable insulation.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state reference map of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1 and Fig. 2, wherein, the represented parts of each sequence number are as follows: 1---hollow insulating bar, 2---metal hook, 3---the first circular hole, 4---secondary shielding annulus, 5---tests heart yearn, and 6---tests shielding line, 7---the first shading ring, 8---the second circular hole, 9---high voltage microammeter, 10-detecting instrument.
A kind of J-1 type 10kV switch cabinet lightning arrester test special pole, comprise hollow insulating bar 1, test heart yearn 5 and test shielding line 6, hollow insulating bar 1 top is provided with metal hook 2, top is provided with the first shading ring 7, middle part arranges the first circular hole 3, described test heart yearn 5 one ends are connected with metal hook 2 bottoms, and the other end extracts from hollow insulating bar 1 by the first circular hole 3; The first circular hole 3 lower ends are provided with secondary shielding annulus 4 and the second circular hole 8, the first circular hole 3 and the second circular hole 8 are at a distance of 5～8 centimeters, secondary shielding annulus 4 is positioned at hollow insulating bar 1 inside, one end of test shielding line 6 is connected with the first shading ring 7, and the other end extracts from the second circular hole 8 by secondary shielding annulus 4.
In use, at first the instrument end connector that will test heart yearn 5 connects detecting instrument 10, to test the other end of shielding line 6 again and receive on the shell of high voltage microammeter 9, and finally metal hook 2 will be connected with lightning arrester, the power supply of opening detecting instrument 10 carries out Insulation Test.The utility model accuracy of measurement is higher, has avoided the false judgment to equipment, has eliminated potential safety hazard.
