[0068] Alternatively, if Figure 1 and Figure 2 As shown, the debugging cabinet further includes an interface module 50 , which is disposed between the connection unit 10 and the controlled loop 20 , and the connection unit 10 is connected to the controlled loop 20 via the interface module 50 .

[0069] For example, Figure 2 Only schematic diagrams of the circuit breaker closing circuit and the circuit breaker opening circuit are given, and schematic diagrams of the closing circuit and the opening circuit of the disconnector and the earthing switch are not given.

[0070] Specifically, see Figure 2 After the control cabinet 40 to be tested and the debugging cabinet are connected to the power supply respectively, first adjust the action time of the time relay KDM to be equal to the spring energy storage time of the actual circuit breaker, wherein the spring energy storage time of the actual circuit breaker is determined by the GIS device body correspondingly controlled by the control cabinet 40 to be tested, and then close the miniature circuit breakers of the control cabinet 40 to be tested and the debugging cabinet respectively ( Figure 2 The schematic diagram of the miniature circuit breaker is not given in the figure) to power it on.

[0071] When the control cabinet 40 to be tested and the debugging cabinet are just powered on, the coil K4 of the first relay KDCK, the coil K5 of the second relay KDDL1, and the coil K6 of the third relay KDDL2 in the display circuit 30 are all de-energized, the contacts 41-42 of the first relay KDCK are closed, the contacts 11-12 of the third relay KDDL2 are closed, the contacts X2-X0 of the first indicator light DW1 are connected, and the first color is displayed, and the contacts X2-X0 of the second indicator light DWCK are connected, and the first color is displayed. Usually, the first color can be set to green, which is used to indicate that each mechanism is open and the circuit breaker closing spring has not stored energy. At the same time, in the controlled circuit 20, the contacts 21-22 of the first relay KDCK are closed, and the "no energy storage" signal is fed back to the control cabinet 40 to be tested, so that the circuit breaker energy storage control circuit in the control cabinet 40 to be tested is connected, and the circuit breaker mechanism motor of the debugging cabinet is started to replace the coil K3 of the time relay KDM of the controlled circuit 20, which is equivalent to the closing spring storing energy.

[0072] When the time relay KDM reaches the set spring energy storage time, the contacts 15-18 of the time relay KDM are closed, the coil K4 of the first relay KDCK is energized, and in the third contact group of the first relay KDCK, the contacts 31-32 are closed and then 31-34 are closed, and the first relay KDCK realizes energized self-holding, and the contacts 41-44 of the first relay KDCK are closed, so that the contacts X1-X0 of the second indicator light DWCK are turned on, and the color of the second indicator light DWCK is changed from the first color to the second color, and the second color is usually set to red. The display unit 302 displays "energy stored" and feeds back the "energy stored" signal to the control cabinet 40 to be detected, and the contacts 21-22 of the first relay KDCK in the controlled loop 20 are disconnected, and the contacts 21-24 are closed, and the relay energy storage control loop is disconnected.

[0073] Subsequently, the contacts of the first relay KDCK change from 11-12 closed to 11-14 closed, and the closing sub-circuit L1 meets the closing conditions. At this time, if the control cabinet 40 to be detected sends a closing command to the closing sub-circuit L1, the coil K1 of the first contactor KDHQ is energized, and the contacts 01-02 of the first contactor KDHQ are closed, so that the coil K5 of the second relay KDDL1 on the first branch is energized, and the coil K6 of the third relay KDDL2 is energized. In the fourth contact group of the second relay KDDL1, the contacts 41-42 are closed and changed to 41-44. Closed, the second relay KDDL1 and the third relay KDDL2 are energized and self-holding, the contacts 11-14 of the third relay KDDL2 are closed, the contacts X1-X0 of the first indicator light DW are turned on, the color of the first indicator light DW changes from the first color to the second color, usually the second color is set to red, the display unit 302 displays the "circuit breaker closing" signal, the contacts 31-34 of the second relay KDDL1 in the controlled loop 20 are closed, and the "circuit breaker closing" signal is fed back to the control cabinet 40 to be tested, which is equivalent to the GIS equipment body completing the circuit breaker closing operation.

[0074] At this time, in the second contact group of the second relay KDDL1, contacts 21-22 are closed and contacts 21-24 are closed, and the opening sub-circuit L2 meets the opening condition. At this time, if the control cabinet 40 to be detected sends an opening command to the opening sub-circuit L2, the coil K2 of the second contactor KDTQ is energized, and the contacts 21-22 of the second contactor KDTQ are opened, so that the coil K5 of the second relay KDDL1 on the first branch is de-energized and the coil K6 of the third relay KDDL2 is de-energized, and the contacts 11-12 of the third relay KDDL2 are closed, and the contacts X2-X0 of the first indicator light DW are turned on, and the color of the first indicator light DW changes from the second color to the first color, and the first color is usually set to green. The display unit 302 displays the "circuit breaker opening" signal, and the contacts 31-32 of the second relay KDDL1 in the controlled loop 20 are closed, and the "circuit breaker opening" signal is fed back to the control cabinet 40 to be detected, which is equivalent to the GIS equipment body completing the circuit breaker opening operation.

[0075] It should be noted that if after closing the miniature circuit breaker, sending the closing command, and sending the opening command, the debugging cabinet and the control cabinet 40 to be tested have no response or have an abnormal response (for example, the display color of the indicator lights is incorrect or no color is displayed), it means that there is a quality problem with the control circuit in the control cabinet 40 to be tested, and power must be cut off for inspection and repair.

[0076] Alternatively, if Figure 2 As shown, the display circuit 30 also includes a first power supply that forms a loop with the first contact group (21, 22) of the first contactor KDHQ, the contact group (15, 16, 18) of the time relay KDM, and the coil K4 of the first relay KDCK.

[0077] The following is a specific example to illustrate the working process of the debugging cabinet of the GIS control system. Specifically, the debugging cabinet of the GIS control system works using the following control method:

[0078] S1, setting the parameters of the time relay in the debugging cabinet to the preset value, wherein the preset value is determined by the spring energy storage time of the GIS equipment body matched with the control cabinet to be tested;

[0079] S2, controlling the control cabinet to be tested and the debugging cabinet to be powered on, and detecting that the first indicator light and the second indicator light in the display unit of the debugging cabinet both display the first color;

[0080] S3, when the spring energy storage time is reached, detecting whether the second indicator light in the display unit of the debugging cabinet changes from the first color to the second color;

[0081] S4, if yes, the energy storage circuit of the circuit breaker of the control cabinet to be tested is normal, otherwise, S105, the energy storage circuit of the circuit breaker is abnormal;

[0083] S6, based on the operation instruction, detecting whether the color change of the indicator light in the display unit of the debugging cabinet is correct;

[0084] S7, if yes, the circuit corresponding to the operation instruction is normal, otherwise, the circuit corresponding to the operation instruction is abnormal.

[0089] S64, if yes, the circuit corresponding to the opening operation instruction is normal, otherwise, the circuit corresponding to the opening operation instruction is abnormal.
