[0014] Figure 1 A schematic diagram of the debugging tooling connection structure provided in an embodiment of the present application. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] like Figure 1 As shown, this embodiment provides a debugging tool for three-remote transmission suitable for a standardized station terminal (DTU), which realizes the transmission of three-remote signals during the transmission process between the terminal and the master station, and consists of a 26+1-core rectangular connector (female), an operation panel and a banana lantern head socket.

[0017] Among them, the 26+1 core rectangular connector (female) complies with the new State Grid standard Q / GDW 11815-2023 Distribution Automation System Terminal Technical Specification D.2.

[0018] Among them, the pin definition of the rectangular connector complies with the new State Grid standard Q / GDW 11815-2023 Distribution Automation System Terminal Technical Specification D.1.2. According to the pin definition, the operation panel can be divided into two parts: remote signaling and remote control.

[0019] The remote signaling signals are brought out from pins 17 to 24. The upload of seven remote signaling signals, including isolating switch position, grounding switch position, control circuit alarm, no energy storage position, remote / local, closed position, and open position, is realized through the toggle switches SB1 to SB6 respectively, and the signal upload status is indicated by LED1 to LED7 indicator lights.

[0020] The remote control part signal is led out from pin 11 to pin 13. The master station remote control signal is sent down, and the corresponding switch KH and switch KF are closed through the control-on relay KH and the control-off relay KF, and the open-close position signal circuit is turned on, which cooperates with the remote control signal circuit to realize the control-open and control-close signal simulation and transmission. The indicator light HLED and the indicator light FLED indicate the remote closing and control-opening status respectively.

[0021] The control-close holding relay KHBC cooperates with its corresponding KHBC normally open contact to achieve self-locking of the closing signal circuit after the main station control-close signal pulse disappears, and keep the closing signal sent up.

[0022] The control-part holding relay KFBC cooperates with its corresponding KFBC normally open contact to realize self-locking of the position signal circuit after the control-part signal pulse of the main station disappears, and keep the position signal sent up.

[0023] The normally closed contact of KFBC is connected in series in the closing signal circuit. When the control and opening command is issued, the switch is opened and the closing signal disappears, preventing the opening and closing signals from appearing at the same time.

[0024] The KHBC normally closed contact is connected in series in the open position signal circuit. When the control closing command is issued, the switch is opened and the open position signal disappears, preventing the open and closed position signals from appearing at the same time.

[0025] Button SB7 and button SB8 are connected in series in the closed position signal circuit and the open position signal circuit respectively. When the remote signal circuit is self-locked after the remote control is issued, the switch position signal is sent up through the button contact.

[0026] Among them, the banana lantern head socket is composed of five colors: yellow, green, red, blue and black, realizing the telemetry part.

[0027] The signal part of the telemetry part is led out from pin 3 to pin 10. The negative pole of current of pin 4, pin 6, pin 8 and pin 10 is short-circuited. Pin 3, pin 5, pin 7, pin 9 and pin 10 are respectively led out to five 4mm banana lantern head sockets of yellow, green, red, blue and black. They are connected to the relay protection instrument through the test line to realize the current signal transmission and complete the telemetry signal matching.

[0028] The optional implementation modes of the embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details in the above implementation modes. Within the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical scheme of the embodiments of the present invention, and these simple modifications all belong to the protection scope of the embodiments of the present invention.
