The utility model discloses the test wire connects for the circular connector, can the lug connection by the end of being surveyed, the test end is direct to be connected relay protection tester through metal plug, and connected mode is simple and convenient, has improved the efficiency of relay protection test.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a relay protection test wire, includes aviation plug and metal plug, the metal plug is connected through the wire respectively aviation plug's contact is right, the quantity of metal plug with aviation plug's contact is right the figure equals. Therefore, when relay protection tests are carried out on automatic equipment control loops, power loops and signal loops such as automatic terminals on power grid distribution columns and feeder automation terminals of distribution stations, the relay protection test line can be adopted, aviation plugs are arranged on the tested terminals, and during the tests, aviation plugs in the relay protection test line are connected with the tested end, and then metal plugs are inserted into corresponding plug holes of a relay protection tester, so that the tests can be carried out; the terminal blocks at the terminal are not required to be connected one by one, and the efficiency of the relay protection test regular inspection is greatly improved.
Furthermore, a part of the conducting wire close to the aviation plug is jointly arranged in an insulating sleeve, and the insulating sleeve is connected with the aviation plug through a stainless steel waterproof connector. Therefore, the wires are wrapped into one bundle, the condition of wired racking cannot occur during testing, and a section of length is reserved at one end of the metal plug to enable the wires to be separated independently, so that the wires can be conveniently and separately inserted into corresponding plug holes of the relay protection tester; the stainless steel waterproof connector is additionally arranged at the joint of the insulating sleeve and the aviation plug, so that the connection is more stable, the corrosion is avoided, and the service life of the device is prolonged.
Furthermore, the aviation plug includes free end aviation plug and fixed aviation plug, the metal plug pass through the wire with the contact of free end aviation plug is to the one-to-one connection, simultaneously the metal plug pass through the wire with the contact of fixed aviation plug is to the one-to-one connection. Thus, a free-end aviation plug and a fixed aviation plug are preset, when the aviation plug of the equipment to be tested is the fixed aviation plug, the testing line is connected by adopting the free-end aviation plug, and when the aviation plug of the equipment to be tested is the free-end aviation plug, the testing line is connected by adopting the fixed aviation plug; different test requirements are met, and the use is more flexible; each pin or jack on the aviation plug corresponds to a metal plug, so that the test requirements can be met.
Preferably, the aviation plug is a pin type aviation plug. Therefore, the cylinder type aviation plug does not need to rotate and can realize the functions of connection, separation and locking only by linear motion; because the relay protection test line needs to be connected and separated frequently; the connection and the separation can be realized more quickly by adopting the pin type aviation plug, and the testing efficiency is improved.
Preferably, the wire is a fireproof insulated wire, and the wire is a single-core shielding wire. Like this, every contact pin or jack on the aviation plug correspond a metal plug, because the wire adopts single core shielding wire, makes the signal transmission of every wire more stable, can not mutual interference, serial number even.
Preferably, the aviation plug is a 4-core aviation plug, a 6-core aviation plug or a 10-core aviation plug. Thus, three test wires adopted in the current relay protection test wire comprise a power input and voltage loop test wire, a protection current loop test wire, a control and signal loop test wire, when the three conventional test wires are manufactured by adopting the utility model, the aviation plugs are 4-core aviation plugs, 6-core aviation plugs and 10-core aviation plugs, and the number of the corresponding metal plugs is not 4, 6 or 10; the conventional requirements can be met; of course, when the terminal aviation of the test is N cores, a corresponding N-core aviation plug relay protection test line can be adopted.
Compared with the prior art, the beneficial effects are:
1. the aviation plug in the relay protection test line is connected with a tested end, and then the metal plug is inserted into a corresponding plug hole of a relay protection tester, so that the test can be carried out; the terminal blocks at the terminal are not required to be connected one by one, and the efficiency of the relay protection test regular inspection is greatly improved.
2. The adoption of the pin type aviation plug can realize connection and separation more quickly and improve the testing efficiency.
