Utility model content
For addressing the above problem, the purpose of this utility model is: provide a kind of VEP type 10kV wheelbarrow switch transmission test special secondary aviation plug, while guaranteeing to do transmission test, can not occur because switch vibrates the wire clamp causing and comes off, is shifted, thereby produce the danger on direct-current short circuit, string road, ensure the safety of the person and equipment.。
The utility model for the technical scheme that its technical matters of solution adopts is:
The special secondary aviation plug of described VEP type 10kV wheelbarrow switch transmission test, comprise the secondary aviation public plug carrying on VEP type 10kV wheelbarrow switch, to should secondary aviation female being set public plug, it is characterized in that, on secondary aviation female, find out four four pairs of pin holes that loop is corresponding when carrying out wheelbarrow switch transmission test, be respectively: motor tank circuit: negative 25, positive 35 a pair of pin holes; Closing locking circuit: negative 20, positive 49 a pair of pin holes; Sub-gate circuit: negative 30, positive 31 a pair of pin holes; Closing circuit: negative 4, positive 14 a pair of pin holes, arrange and above-mentioned four pairs of holes that pin hole is corresponding at the secondary aviation female back side, 8 insulated conductor one end and 8 eyelet weldings are connected together, weld exposed metal/bare metal part is carried out insulation-encapsulated, the attachment plug of the insulated conductor other end, plug and transmission test case jack adapt.
Wherein, 3 meters of described insulated conductor length, 2 millimeters of diameters.
Doing before transmission test, Connection Step of the present utility model is as follows:
1. the secondary aviation public plug of secondary aviation female and 10kV wheelbarrow switch is plugged in together;
2. 2 insulated conductors that are connected with a pair of pin hole of motor tank circuit are plugged into a pair of 220V DC output end mouth of transmission test case;
3. another that 2 insulated conductors that are connected with a pair of pin hole of closing locking circuit is plugged into transmission test case is to 220V DC output end mouth;
4. in the time doing point brake test, 2 insulated conductors that are connected with a pair of pin hole of sub-gate circuit are plugged into the adjustable output port of transmission test case 0-220V direct current;
5. in the time doing combined floodgate test, 2 insulated conductors that are connected with a pair of pin hole of closing circuit are plugged into the adjustable output port of transmission test case 0-220V direct current;
After having connected, can carry out transmission test to 10kV wheelbarrow switch.Utilize the utility model just can not occur in the time doing transmission test because switch vibrate the direct-current short circuit that the wire clamp that causes comes off, be shifted and cause, the danger on string road, the safety of the personal and equipment of guarantee.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is transformed secondary aviation female corresponding the secondary aviation public plug carrying on VEP type 10kV wheelbarrow switch, on female, find out the loop of respectively corresponding 4 the test use of 4 pairs of pin holes, it is motor tank circuit, closing locking circuit, sub-gate circuit and closing circuit, get out at the secondary aviation female back side and 4 pairs of holes that pin hole is corresponding above, insulated conductor is connected with respective aperture, wire opposite side can be connected on transmission test case, in transmission test process, just can not occur because switch vibrates the wire clamp causing and comes off, the direct-current short circuit being shifted and cause, string road danger, ensure the safety of the person and equipment.
