Description

TECHNICAL FIELD

[0002] The voltage and current are injected into the power distribution automation terminal for debugging test, mainly to verify the collection accuracy of the terminal measurement circuit under controllable conditions, verify the action reliability of the protection and control logic, detect the integrity and time delay of communication and data uploading, find and eliminate secondary circuit or wiring hidden dangers, so as to ensure that the terminal can accurately monitor, quickly respond and safely operate after being put into operation.

[0003] The pole-mounted circuit breaker and its matching terminal widely used in power distribution network of power system must be subjected to workshop debugging test before being put into network. During the debugging test, the power distribution terminal needs to be disassembled and the protective cover is removed, and then the debugging and test are carried out by connecting the terminal circuit with a relay protection instrument and other devices through a connecting line. After the debugging and test are completed, the power distribution terminal is reassembled and the protective cover is put back.

[0004] Publication No. CN115684803A discloses a convenient debugging device for a power distribution terminal, which comprises a terminal block for connecting a relay protection instrument and other devices for debugging test, an aviation plug connected to the terminal block through a multi-core cable harness at one end, and the other end of the aviation plug being used for being plugged into an aviation socket of the power distribution terminal. The convenient debugging device for the power distribution terminal is simple and easy to use. The voltage and current can be injected and the debugging and test can be carried out on the terminal block only by plugging the aviation plug into the aviation socket of the power distribution terminal, which saves time, reduces the time for disassembling and assembling the protective cover of the power distribution terminal, reduces the disassembly and assembly steps, especially reduces the disconnection step on the line board of the power distribution terminal, thereby avoiding the problems of poor contact and the like, improving the work efficiency of the debugging test of the power distribution terminal, and greatly saving the time for debugging and test.

[0005] The technical scheme avoids the problem of long time consumption for connecting the line after disassembling the power distribution terminal by installing the aviation plug on the aviation socket of the power distribution terminal and connecting the terminal block with the voltage injection device and the current injection device. However, during the debugging process after the power distribution terminal is put into operation, the aviation plug originally installed on the aviation socket of the power distribution terminal still needs to be disassembled for debugging. Since the terminal block and the aviation socket are connected through the multi-core cable harness, it is inconvenient to place the terminal block in the indoor power distribution terminal, and the terminal block needs to be held or falls in the state of its own gravity, which easily affects the connection stability of the multi-core cable harness.

The first component 1 can be connected with the second component 2.

[0060] The first component 1 comprises a conversion plug 11 installed on the power distribution terminal aviation socket and used for connecting the power distribution terminal aviation socket and the aviation plug, one end of the conversion plug 11 is connected with the aviation socket, and the other end is connected with the aviation plug, one end of the corresponding conversion plug 11 is configured as a wire insertion rod 1110, and the other end is configured as a wire insertion hole 1111, so as to facilitate the connection of the aviation plug and the aviation socket.

[0061] The first component 1 further comprises a wire head 12 arranged outside the conversion plug 11, the wire head 12 is electrically connected with the wire insertion hole 1111 through a first cable harness 13, and the first cable harness 13 can be used to inject current or voltage into the power distribution terminal during current injection and voltage injection.

[0062] The wire head 12 is provided with a plurality of sockets 119 corresponding to the wire insertion hole 1111, and each socket 119 is marked corresponding to the wire insertion hole 1111, so as to facilitate the identification during current injection or voltage injection.

[0065] The mounting head 21 is provided with a second cable harness 22 on one side and connected with the second cable harness 22, and one end of the second cable harness 22 away from the mounting head 21 is provided with a connecting structure 23 connected with the voltage injection equipment or the current injection equipment, which is not limited in the embodiment, and the connecting structure 23 can be adjusted according to the output state of the equipment. For example, the connecting structure 23 is a plug, a clamp, etc.

[0066] In order to avoid the problem that the stability is reduced due to the pulling of the second cable harness 22 by gravity, a fixing member 24 is arranged outside the second cable harness 22, and the fixing member 24 fixes the second cable harness 22 outside the power distribution terminal.

[0067] In the fixing member 24, the second cable harness 22 is threaded through the magnetic structure, and the magnetic structure is arranged to be connected to the surface of the second cable harness 22 so as to change the position of the magnetic structure, because the height and other parameters of the power distribution terminal of different structures are different.
